Long-Term Functional Outcomes After Laparoscopic and Open Rectopexy for the Treatment of Rectal Prolapse

Purpose  Laparoscopic rectopexy to treat full-thickness rectal prolapse has proven short-term benefits, but there is little long-term follow-up and functional outcome data available. Methods  Patients who had abdominal surgery for prolapse during a ten-year period were identified and interviewed to ascertain details of prolapse recurrence, constipation, incontinence, cosmesis, and satisfaction. Additional details on recurrences that required surgery and mortality were obtained from chart review and the State Death Registry. Results  Of 321 prolapse operations, laparoscopic rectopexy was performed in 126 patients, open rectopexy in 46, and resection rectopexy in 21 patients. At a median follow-up of five years after laparoscopic rectopexy, there were five (4 percent) confirmed full-thickness recurrences that required surgery. Actuarial recurrence rates of laparoscopic rectopexy were 6.9 percent at five years (95 percent confidence interval, 0.1–13.8 percent) and 10.8 percent at ten years (95 percent confidence interval, 0.9–20.1 percent). Seven patients underwent rubber band ligation for mucosal prolapse and seven required other surgical procedures. There was one recurrence after open rectopexy (2.4 percent) and one after resection rectopexy (4.7 percent), and there was no significant difference between groups. Overall constipation scores were not increased after laparoscopic rectopexy, with no significant difference to open rectopexy or resection rectopexy. Conclusions  This study has demonstrated that laparoscopic rectopexy has reliable long-term results for treating rectal prolapse, including low recurrence rates and no overall change in functional outcomes.

Ripstein procedure is an effective treatment for rectal prolapse without constipation

The operation of choice for complete rectal prolapse is controversial. We reviewed 169 patients undergoing 185 surgical procedures for rectal prolapse over a 27-year period. The most common surgical procedure employed was the Ripstein procedure (n=142) and is the focus of this report. Other surgical procedures used included resection rectopexy (n=18), anterior resection (n=7), Altemeier's (n=9), Delorme's (n=2), and anal encirclement (n=7). The median age was 59 years (range, 12–94 years), and the female-to-male ratio was 51. The incidence of fecal incontinence, solitary rectal ulcer syndrome, and prior surgery elsewhere for rectal prolapse was 40 percent, 12 percent, and 19 percent, respectively. Operative mortality was 0.6 percent; morbidity was 16 percent. Median follow-up was 4.2 years (range, 1–15 years). Complete recurrence of prolapse after the Ripstein procedure was 8 percent; one-third of these patients recurred 3 to 14 years after surgery. Fecal incontinence improved after the Ripstein procedure or resection rectopexy in about half the patients. Persistence of prior constipation was more common after the Ripstein procedure than after resection rectopexy (57 percent vs. 17 percent;P=0.03, chi-squared). Fifteen patients developed constipation for the first time after the Ripstein procedure. About one in three patients, irrespective of surgical procedures, remained dissatisfied with the final outcome despite anatomic correction of the prolapse. The Ripstein procedure has proven to be a safe procedure with good anatomic repair of the prolapse and may improve continence. In the presence of constipation, procedures other than the Ripstein procedure may be preferable.Read in part at the meeting of The American Society of Colon and Rectal Surgeons, San Francisco, California, June 7 to 12, 1992.     

Laparoscopic suture rectopexy without resection is effective treatment for full-thickness rectal prolapse

PURPOSE: The study was undertaken to evaluate the role of laparoscopic suture rectopexy without resection as a safe and effective treatment for full-thickness rectal prolapse. METHOD: Data were prospectively collected and analyzed on 25 patients who underwent laparoscopic rectopexy without resection for full-thickness rectal prolapse between October 1994 and July 1998. Four patients had conversions from laparoscopic to open surgery. Two patients had recurrent prolapse previously managed by Delorme's procedure. Another two patients had solitary rectal ulcer syndrome associated with their full-thickness rectal prolapse. There were a total of three males. Mean age was 72 (range, 37–89) years. The preoperative and postoperative course of each patient was followed up, with attention paid to first bowel movement, hospital stay, duration of surgery, fecal incontinence, constipation, recurrent prolapse, morbidity, and mortality. Follow-up was made by clinic appointments and, if necessary, by telephone review. RESULTS: Median follow-up period was 26 (range, 1–41) months. Mean duration of surgery was 96 (range, 50–150) minutes. Postoperatively, the median time for first bowel movement was four (range, 2–10) days. Median hospital stay was seven (range, 3–23) days. Overall, 15 patients (60 percent) either improved or remained unchanged with respect to continence. There was an improvement in 10 of 20 patients (50 percent) among those with continence Grade 2 or more (P<0.05). Seven patients (28 percent) remained incontinent. No patient became more incontinent after surgery. Constipation, which was present in 9 patients (36 percent) preoperatively, affected 11 patients (44 percent) after rectopexy (P>0.05; not significant). Postoperative morbidity included a port site hernia and deep venous thrombosis in one patient, a repaired rectal perforation, a retroperitoneal hematoma with prolonged ileus (1 case), and a superficial wound infection (1 case). One patient with solitary rectal ulcer syndrome in the laparoscopic surgery group remained unhealed despite resolution of the rectal prolapse after rectopexy and required abdominoperineal resection. Two patients (laparoscopic surgery = 1 and open surgery = 1) had severe constipation after surgery and both required loop colostomies. There were no cases of operative mortality or recurrent prolapse. CONCLUSION: Laparoscopic suture rectopexy without resection is both safe and effective in this frequently frail population and offers a minimally invasive approach that may have potential advantages for selected groups of patients with full-thickness rectal prolapse.Mr. Hartley was supported by an education grant from Autosuture UK.Presented in part to the Association of Surgeons of Great Britain and Ireland, Brighton, United Kingdom, May 4 to 7 1999.     

Complete rectal prolapse

Optional treatment for complete rectal prolapse remains controversial. PURPOSE: We reviewed our experience over a 19-year period to assess trends in choice of operation, recurrence rates, and functional results. METHODS: We identified 372 patients who underwent surgery for complete rectal prolapse between 1976 and 1994. Charts were reviewed and follow-up (median, 64; range, 12–231 months) was obtained by mailed questionnaire (149 patients; 40 percent) and telephone interview (35 patients; 9 percent). Functional results were obtained from 184 responders (49 percent). RESULTS: Median age of patients was 64 (11–100) years, and females outnumbered males by nine to one. One-hundred and eighty-eight patients (51 percent) were lost to follow-up; 183 patients (49 percent) underwent perineal rectosigmoidectomy, and 161 patients (43 percent) underwent abdominal rectopexy with bowel resection. The percentage of patients who underwent perineal rectosigmoidectomy increased from 22 percent in the first five years of the study to 79 percent in the most recent five years. Patients undergoing perineal rectosigmoidectomy were more likely to have associated medical problems as compared with patients undergoing abdominal rectopexy (61vs. 30 percent,P=0.00001). There was no significant difference in morbidity, with 14 percent for perineal rectosigmoidectomyvs. 20 percent for abdominal rectopexy. Abdominal procedures were associated with a longer length of stay as compared with perineal rectosigmoidectomy (8vs. 5 days,P=0.001). Perineal procedures, however, had a higher recurrence rate (16vs. 5 percent,P=0.002). Functional improvement was not significantly different, and most patients were satisfied with treatment and outcome. CONCLUSIONS: We conclude that abdominal rectopexy with bowel resection is associated with low recurrence rates. Perineal rectosigmoidectomy provides lower morbidity and shorter length of stay, but recurrence rates are much higher. Despite this, perineal rectosigmoidectomy has appeal as a lesser procedure for elderly patients or those patients in the high surgical risk category. For younger patients, the benefits of perineal rectosigmoidectomy being a lesser procedure must be weighed against a higher recurrence rate.Read at the meeting of The American Society of Colon and Rectal Surgeons, Seattle, Washington, June 9 to 14, 1996, and at the Tripartite Meeting, London, United Kingdom, July 8 to 10, 1996.     

Laparoscopic surgery for rectal prolapse and outlet obstruction

PURPOSE: The aim of this study was to assess the outcome of both laparoscopic suture rectopexy and resection-rectopexy in the treatment of complete and incomplete rectal prolapse, outlet obstruction, or both. METHODS: Data from surgery were collected prospectively. Semiannual follow-up was performed by assessment of recurrence, continence, and constipation using patients' history, physical examination, continence score, and anorectal manometry. Statistical analysis was performed by chi-squared test and Student'st-test (P<0.05 was accepted as statistically significant). RESULTS: Between September 1992 and February 1997, 72 patients (68 females) with a mean age of 62 (range, 23–88) years were treated laparoscopically. Indications for surgery were rectal prolapse in 21 patients, rectal prolapse combined with outlet obstruction in 36 patients, and outlet obstruction alone in 15 patients. Standard procedure was a laparoscopic suture rectopexy. A sigmoid resection was added in 40 patients. Mean duration of surgery was 227 (range, 125–360) minutes for rectopexy and 258 (range, 150–380) minutes for resection-rectopexy. Conversion was necessary in 1.4 percent (n=1). Overall complication rate was 9.7 percent (n=7) and mortality rate was 0 percent. Mean postoperative hospitalization was 15 (range, 6–47) days. All patients with a minimal follow-up of two years (n=53) could be enrolled in a prospective follow-up study (mean follow-up, 30 months). No recurrence of rectal prolapse had to be recognized. Sixty-four percent of patients with incontinence before surgery were continent or had improved continence. In patients experiencing constipation preoperatively, constipation was improved or completely removed in 76 percent. No additional symptoms of constipation occurred after surgery. CONCLUSION: Laparoscopic procedures in the treatment of pelvic floor disorders,e.g., rectal prolapse or outlet obstruction, lead to acceptable functional results. However, follow-up has to be extended and long-term results of recurrence, continence, and constipation have to be evaluated.     

Long-Term Results of Delorme’s Procedure and Orr–Loygue Rectopexy to Treat Complete Rectal Prolapse

PURPOSE The aim of this study was to assess long-term outcome of Orr–Loygue rectopexy and Delorme’s procedures in total rectal prolapse management.METHODS Data were collected retrospectively from 1978 to 2001. Statistical analysis was performed by chi-squared test and Student’s t -test.RESULTS One hundred nine patients underwent either a Orr–Loygue rectopexy (49 patients) or a Delorme’s procedure (60 patients). Mean follow-up was 88 (range, 1–300) months. In the rectopexy group, the overall complication rate and the recurrence rate were 33 percent and 4 percent, respectively. In patients with preoperative constipation, this symptom was improved or completely resolved in 33 percent and worsened in 58 percent postoperatively. Seventy-three percent of patients with preoperative incontinence were continent or had continence improvement postoperatively. In Delorme’s group, overall complication and recurrence rates were 15 percent and 23 percent, respectively. Mortality was 7 percent. In patients with preoperative constipation, this symtom was improved or completely resolved in 54 percent and worsened in 12.5 percent of patients postoperatively. Forty-two percent of patients with preoperative incontinence were continent or had continence improvement postoperatively.CONCLUSIONS In this study, Orr–Loygue rectopexy had a lower long-term recurrence rate. However, this surgical procedure is associated with a higher complication rate. We believe that Delorme’s procedure is still a valuable option in selected patients with postoperative minimal morbidity but higher recurrence rate.     

Functional results of operative treatment of rectal prolapse over an 11-year period

PURPOSE: A variety of surgical procedures have been developed to treat rectal prolapse, but there is still no consensus on the operation of choice. The aim of this study was to evaluate the functional results of operative treatment of rectal prolapse during an 11-year period in our department. METHODS: All patients treated for complete rectal prolapse during an 11-year period, from 1985 to 1995, in a single university hospital were included. Of the 123 patients, 22 were men, and the mean age was 59 (range, 15–88) years. The medical records of all patients were reviewed retrospectively, and a questionnaire on bowel symptoms before and after surgery was sent to all 95 living patients. RESULTS: The majority of the procedures (91 percent) were performed by abdominal approach, and the most frequently used open technique was posterior rectopexy with mesh (78 percent). Of the incontinent patients, 35 (63 percent), all those less than 40 years of age and 64 percent of those 40 years or older, were continent postoperatively (P=0.0001) after a median follow-up of five (range, 1–72) months. According to the questionnaire, after a median follow-up of 85 (range, 16–144) months, only 38 percent of the incontinent patients in the mesh or suture group, 78 percent of patients less than 40 years of age (n=18), and 52 percent of those 40 years or older (n=47) claimed to be continent postoperatively. The proportion of patients with constipation was greater after the operation than preoperatively (P=0.02) and more patients used medication for constipation after than before the operation (P=0.0001). The overall complication rate was 15 percent, and the mortality rate was 1 percent (1/123). In the mesh or suture group there were 6 (6 percent) recurrent complete prolapses and 11 (12 percent) mucous prolapses. CONCLUSION: Posterior rectopexy with mesh gave good results in our hands. Older age and longer follow-up seem to have a negative effect on the functional outcome of the operation and on the recurrence rate.Supported by a grant from the Medical Research Fund of the Tampere University Hospital.     

Management of Rectal Prolapse in Children

PURPOSE Rectal prolapse in children is not uncommon and usually is a self-limiting condition in infancy. Most cases respond to conservative management; however, surgery is occasionally required in cases that are intractable to conservative treatment. This study was designed to analyze the outcomes of rectal prolapse in children and to propose a pathway for the management of these cases in children.METHODS A retrospective analysis of all cases of rectal prolapse referred to our surgical unit during a period of five years was performed. End point was recurrence of prolapse requiring manual reduction under sedation or an anesthetic. Results are presented as median (range) and statistical analysis was performed using chi-squared test; P < 0.05 was considered significant.RESULTS A total of 49 children (25 males) presented with symptoms of rectal prolapse at a median age of 2.6 years (range, 4 months –10.6 years). All children received an initial period of conservative treatment with watchful expectancy and/or laxatives. Twenty-five patients were managed conservatively without any additional procedures (Group A), and 24 patients had one or more interventions, such as injection sclerotherapy, Thiersch procedure, anal stretch, banding of prolapse, and rectopexy (Group B). Management of rectal prolapse was successful with no recurrences in 24 patients (96 percent) in Group A vs. 15 patients (63 percent) in Group B at a median follow-up period of 14 (range, 2–96) months. An underlying condition was found in 84 percent of patients in Group A vs. 54 percent in Group B (P = 0.024). The age at presentation was younger than four years in 88 percent of patients in Group A vs. 58 percent in Group B (P = 0.019).CONCLUSIONS Rectal prolapse in children does respond to conservative management. A decision to operate is based on age of patient, duration of conservative management, and frequency of recurrent prolapse (>2 episodes requiring manual reduction) along with symptoms of pain, rectal bleeding, and perianal excoriation because of recurrent prolapse. Those cases presenting younger than four years of age and with an associated condition have a better prognosis. The authors propose an algorithm for the management of rectal prolapse in children.     

Laparoscopic-assisted resection-rectopexy for rectal prolapse

PURPOSE: Objectives of this study were to describe the technique of laparoscopic-assisted resection rectopexy and audit the clinical outcomes, including review of functional results. METHODS: Data were prospectively collected for duration of operation, time to passage of flatus and feces postoperatively, hospital stay, morbidity, and mortality. Follow-up was performed by an independent assessor using a standardized questionnaire. Patients were also assessed by clinical review or telephone interview. RESULTS: During a four-year period, 34 patients underwent laparoscopic repair for rectal prolapse, of which 30 patients underwent laparoscopic-assisted resection rectopexy. Median duration of the operations was 185 minutes, median time for passage of flatus was two days postoperatively, and median length of hospital stay was five days. Morbidity was 13 percent and mortality rate was 3 percent. Comparison between the first ten patients who underwent laparoscopic-assisted resection rectopexy and the last ten revealed a significant reduction in both median duration of operating time (224vs. 163 minutes;P<0.005) and length of stay (6vs. 4 days;P<0.015). Follow-up study conducted at a median time of 18 months revealed that most patients (92 percent) felt that the operation had improved their symptoms, that incontinence was improved in 14 of 20 patients with impaired continence (70 percent), and that constipation was improved in 64 percent. Symptoms of incomplete emptying and the need to strain at stool were both improved in 62 and 59 percent of patients, respectively. No full-thickness recurrences have occurred, but two patients have had mucosal prolapse detected (7 percent) and treated. CONCLUSION: Laparoscopic-assisted resection rectopexy is feasible and safe, with acceptable recurrence rates and functional results compared with the open procedure in the surgical literature. There is rapid return of intestinal function associated with an early discharge from hospital.Read at the meeting of The Royal Australasian College of Surgeons, Brisbane, Australia, May 11 to 15, 1997.     

Recurrent rectal prolapse

PURPOSE: The aim of this study was to assess the clinical and functional outcome of surgery for recurrent rectal prolapse and compare it with the outcome of patients who underwent primary operation for rectal prolapse. METHODS: All patients who underwent surgery for rectal prolapse were evaluated for age, gender, procedure, anorectal manometry and electromyography findings, and morbidity. The results for patients who underwent surgery for recurrent rectal prolapse were compared with a group of patients matched for age, gender, surgeon, and procedure who underwent primary operations for rectal prolapse. RESULTS: A total of 115 patients underwent surgery for rectal prolapse. Twenty-seven patients, 10 initially operated on at this institution and 17 operated on elsewhere, underwent surgery for recurrent rectal prolapse. These 27 patients were compared with 27 patients with primary rectal prolapse operated on in our department. In the recurrent rectal prolapse group, prior surgery included rectopexy in 7 patients, Delorme's procedure in 7 patients, perineal rectosigmoidectomy in 7 patients, anal encirclement procedure in 4 patients, and resection rectopexy in 2 patients. Operations performed for recurrence were perineal rectosigmoidectomy in 14 patients, resection rectopexy in 8 patients, rectopexy in 2 patients, pelvic floor repair in 2 patients, and Delorme's procedure in 1 patient. There were no statistically significant differences between the groups in preoperative incontinence score (recurrent rectal prolapse, 13.6±7.8vs. rectal prolapse, 12.7±7.2; range, 0–20) or manometric or electromyography findings, and there were no significant differences in mortality (0vs. 3.7 percent), mean hospital stay (5.4±2.5vs. 6.9±2.8 days), anastomotic complications (anastomotic stricture (0vs. 7.4 percent), anastomotic leak (3.7vs. 3.7 percent) and wound infection (3.7vs. 0 percent)), postoperative incontinence score (2.8±4.8vs. 1.5±2.7), or recurrence rate (14.8vs. 11.1 percent) between the two groups at a mean follow-up of 23.9 (range, 6–68) and 22 (range, 5–55) months, respectively. The overall success rate for recurrent rectal prolapse was 85.2 percent. CONCLUSION: The outcome of surgery for rectal prolapse is similar in cases of primary or recurrent prolapse. The same surgical options are valid in both scenarios.Funded in part by a generous grant from the Eleanor Naylor Dana Charitable Trust Fund and the Caporella Family.Poster presentation at the meeting of The American Society of Colon and Rectal Surgeons, Philadelphia, Pennsylvania, June 22 to 26, 1997.     

Laparoscopically-Assisted Resection Rectopexy for Rectal Prolapse: Ten Years’ Experience

PURPOSE This study has been undertaken to audit a single-center experience with laparoscopically-assisted resection rectopexy for full-thickness rectal prolapse. The clinical outcomes and long-term results were evaluated.METHODS The data were prospectively collected for the duration of the operation, time to passage of flatus postoperatively, hospital stay, morbidity, and mortality. For follow-up, patients received a questionnaire or were contacted. The data were divided into quartiles over the study period, and the differences in operating time and length of hospital stay were tested using the Kruskal-Wallis test.RESULTS Between March 1992 and October 2003, a total of 117 patients underwent laparoscopic resection rectopexy for rectal prolapse. The median operating time during the first quartile (representing the early experience) was 180 minutes compared with 110 minutes for the fourth quartile (Kruskal-Wallis test for operating time = 35.523, 3 df, P < 0.0001). Overall morbidity was 9 percent (ten patients), with one death (<1 percent). One patient had a ureteric injury requiring conversion. One minor anastomotic leak occurred, necessitating laparoscopic evacuation of a pelvic abscess. Altogether, 77 patients were available for follow-up. The median follow-up was 62 months. Eighty percent of the patients reported alleviation of their symptoms after the operation. Sixty-nine percent of the constipated patients experienced an improvement in bowel frequency. No patient had new or worsening symptoms of constipation after surgery. Two (2.5 percent) patients had full-thickness rectal prolapse recurrence. Mucosal prolapse recurred in 14 (18 percent) patients. Anastomotic dilation was performed for stricture in five (4 percent) patients.CONCLUSIONS Laparoscopically-assisted resection rectopexy for rectal prolapse provides a favorable functional outcome and low recurrence rate. Shorter operating time is achieved with experience. The minimally invasive technique benefits should be considered when offering rectal prolapse patients a transabdominal approach for repair, and emphasis should now be on advanced training in the laparoscopic approach.Reprints are not available.Presented at the meeting of The American Society of Colon and Rectal Surgeons, Dallas, Texas, May 8 to 13, 2004     

Surgery for Rectal Prolapse: Orr-Loygue Ventral Rectopexy With Limited Dissection Prevents Postoperative-Induced Constipation Without Increasing Recurrence

Purpose Abdominal rectopexy is the preferred surgical technique for the treatment of total rectal prolapse. In many reported series, its results are impaired by induced constipation. Lateral rectal ligaments preservation could prevent constipation but increase recurrence rates. We report anatomic and functional results of abdominal Orr-Loygue ventral rectopexy with dissection limited to anterior and posterior rectal wall. Methods Consecutive patients with total rectal prolapse or intra-anal rectal prolapse associated to fecal incontinence or outlet obstruction were treated by abdominal rectopexy. Recurrences, correction of symptoms, and induced constipation were prospectively analyzed. Results Seventy-three patients were treated between 1993 and 2004. Recurrence was observed in 3 of 73 patients (4.1 percent) after a mean follow-up period of 28.6 (range, 6–84) months. Overall patient satisfaction (correction of prolapse, incontinence, and/or outlet obstruction) after the procedure was classified in three categories: Cured: n = 45 (61.6 percent); Improved: n = 24 (32.9 percent); Failure: n = 4 (5.5 percent). Postoperative constipation appeared in 2 of 36 (5.5 percent) preoperatively nonconstipated patients and worsened in 2 of 37 (5.4 percent) preoperatively constipated patients. Conclusions Orr-Loygue abdominal ventral rectopexy with limited dissection and preservation of rectal lateral ligaments is a safe and effective procedure for the treatment of complete rectal prolapse, or internal prolapse associated with fecal incontinence or outlet obstruction. Preservation of lateral ligaments seems to prevent postoperative constipation without increasing the risk of prolapse recurrence.     

A Comparison of Open vs. Laparoscopic Abdominal Rectopexy for Full-Thickness Rectal Prolapse: A Meta-Analysis

PURPOSE Using meta-analytical techniques, this study was designed to compare open and laparoscopic abdominal procedures used to treat full-thickness rectal prolapse in adults. METHODS Comparative studies published between 1995 and 2003, cited in the literature of open abdominal rectopexy vs. laparoscopic abdominal rectopexy, were used. The primary end points were recurrence and morbidity, and the secondary end points assessed were operative time and length of hospital stay. A random effect model was used to aggregate the studies reporting these outcomes, and heterogeneity was assessed. RESULTS Six studies, consisting of a total of 195 patients (98 open and 97 laparoscopic) were included. Analysis of the data suggested that there is no significant difference in recurrence and morbidity between laparoscopic abdominal rectopexy and open abdominal rectopexy. Length of stay was significantly reduced in the laparoscopic group by 3.5 days (95 percent confidence interval, 3.1–4; P < 0.01), whereas the operative time was significantly longer in this group, by approximately 60 minutes (60.38 minutes; 95 percent confidence interval, 49–71.8). CONCLUSIONS Laparoscopic abdominal rectopexy is a safe and feasible procedure, which may compare equally with the open technique with regards to recurrence and morbidity and favorably with length of stay. However large-scale randomized trials, with comparative, sound methodology are still needed to ascertain detailed outcome measures accurately.     

Results of Delorme's procedure for rectal prolapse

PURPOSE: A retrospective study was undertaken to assess the results of Delorme's procedure for rectal prolapse and to determine the advantages of an innovative extended transrectal repair, which aims at performing a total pelvic floor repair. METHODS: A total of 85 patients, ranging in age from 21 to 97 years, were operated on. Sixty-five (82 percent) patients had varying degrees of fecal incontinence. Similar groups of patients were compared with regard to control of the prolapse and restoration of continence according to 1) age and medical condition and 2) operative technique: original vs.extended operation. RESULTS: Twelve patients (14 percent) developed postoperative complications. There was one perioperative death (1.2 percent). Eighty patients were followed for 6 to 136 (median, 33) months. Eleven (13.5 percent) developed recurrent full-thickness prolapse. The recurrence rate was significantly different 1) between 44 elderly and poor operative risk patients not suitable for abdominal surgery (22.5 percent) and 41 younger patients without concurrent medical conditions, electively submitted to perineal repair (5 percent) (P <0.05), and 2) between the original procedure (21 percent of 44 patients) and the modified technique (5 percent of 41 patients) (P <0.05). Forty five patients (69 percent) improved or regained full continence. No patient worsened. No residual dysfunction was induced. Restoration of continence was not influenced by selection of patients or surgical technique. CONCLUSIONS: Despite increased morbidity (22 percent; P <0.05), advantages of the modified technique were 1) over the original procedure, a reduced recurrence rate, 2) over perineal proctectomy, the absence of coloanal anastomosis and better functional outcome, and 3) over abdominal rectopexy, a less aggressive approach without disturbing effects on bowel habits.     

Rectal cancer

PURPOSE: This study was designed to assess the local recurrence rate and prognostic factors for local recurrence in patients undergoing curative anterior or abdominoperineal resections without radiotherapy. METHODS: From January 1980 to December 1996, 514 consecutive patients underwent curative resections for rectal cancer. We excluded those with preoperative radiotherapy (n=23), postoperative radiotherapy (n=27), local resection (n=36), and 11 (2.1 percent) patients who died postoperatively. The remaining 417 patients (249 males) with a median age of 64 (range, 21–90) years were analyzed. For upper third lesions, mesorectal tissue was excised down to at least 5 cm below the tumor. Total mesorectal excision was performed for lower and middle tumors. Postoperative chemotherapy was limited to patients with Stage III lesions. Median follow-up (and 95 percent confidence interval) was (5.2 4.3–5.9) years, with 87.7 percent of patients followed up longer than 24 months. Local recurrence was defined as any recurrence within the field of resection, regardless of the presence or absence of distant metastasis. RESULTS: Five-year local recurrence rate(and 95 percent confidence interval) was 9.7 (6.4–13) percent, with a median time to diagnosis of 15 (10–23) months. Local recurrence rates in Stages I, II, and III were: 3.1, 4.1, and 24.1 percent, respectively (P < 0.0001). In relation to node status, local recurrence rates were N0, 4.1 (1.7–6.5) percent; N1, 12.6 (4.6–20.6) percent; N2, 32.1 (12.1–52.1) percent; and N3, 59.3 (22.5–96.1) percent; (P < 0.00001). Lower third tumors had a higher local recurrence rate than middle and upper third tumors: 17.9, 7.1, and 5.1 percent, respectively (P=0.002). Adjusted by stage, this difference was maintained only in Stage III tumors. Among lower tumors, those at 6 and 7 cm from the anal verge had a lower local recurrence rate than those below 6 cm (6.7vs. 26.2 percent, respectively;P=0.02). Accidental rectal perforation at or near the tumor site occurred in 12 cases (2.9 percent), showing a strong correlation with local recurrence (P < 0.0001). Multivariate analysis showed significant higher risk for lower third tumors (hazard ratio, 2.98) and positive nodes (hazard ratio, 4.78). CONCLUSIONS: Appropriate surgery without irradiation achieves excellent local control in N0 rectal cancers. Node metastasis, lower third localization (especially below 6 cm), and accidental rectal perforation at or near the tumor site are significantly associated with a higher local recurrence rate.     

Results of Delorme's procedure for rectal prolapse

PURPOSE: This study was designed to examine the results of Delorme's procedure. METHODS: Thirty-two patients (24 males and 8 females, mean age, 70 years) underwent Delorme's procedure between 1978 and 1990 following symptoms lasting between two weeks and ten years. Thirteen patients had had 21 previous operations for prolapse. RESULTS: The mean operation time was 65 minutes. No blood transfusions were needed, there was no operative mortality, and only two patients had complications (one chest infection and one anastomotic dehiscence). No patients were lost to follow-up. Over a mean follow-up of 24 months (4 months to 4 years), 9 patients died of unrelated conditions. There were four recurrences (12.5 percent), two in patients who had each had two previous procedures. Incontinence improved in 46 percent. No patient became constipated and 50 percent of those constipated preoperatively improved. CONCLUSION: Although abdominal rectopexy is safe and has a low recurrence rate (<5 percent), it involves the hazards of a laparotomy. In addition, up to 40 percent of patients become constipated after rectopexy which may be debilitating. Delorme's procedure has a low morbidity, results in good bowel function, and has a low recurrence rate. It can be performed on unfit patients with possible advantages over rectopexy and perhaps should be used more readily.     

Management of Recurrent Rectal Prolapse: Surgical Approach Influences Outcome

Introduction Recurrent rectal prolapse is an unresolved problem and the optimal treatment is debated. This study was designed to review patterns of care and outcomes in a large cohort of patients after surgery for recurrent prolapse. Methods From 685 patients who underwent operative repair for full-thickness external rectal prolapse, we identified 78 patients (70 females; mean age, 66.9 years) who underwent surgery for recurrence. We reviewed the subsequent management and outcomes for these 78 patients. Results Mean interval to their first recurrence was 33 (range, 1–168) months. There were significantly more re-recurrences after reoperation using a perineal procedure (19/51) compared with an abdominal procedure (4/27) for their recurrent rectal prolapse (P = 0.03) at a mean follow-up of nine (range, 1–82) months. Patients undergoing abdominal repair of recurrence were significantly younger than those who underwent perineal repair (mean age, 58.5 vs. 71.5 years; P < 0.01); however, there was nosignificant difference between the two groups with regard to the American Society of Anesthesiologists classification (P = 0.89). Eighteen patients had surgery for a second recurrence, with perineal repairs associated with higher failure rates (50 vs. 8 percent; P = 0.07). Finally, when combining all repairs, the abdominal approach continued to have significantly lower recurrence rates (39 vs. 13 percent; P < 0.01). Conclusions The re-recurrence rate after surgery for recurrent rectal prolapse is high, even at a relatively short follow-up interval. Our data suggest that abdominal repair of recurrent rectal prolapse should be undertaken if the patient's risk profile permits this approach.

Adjuvant interferon for anal condyloma

PURPOSE: The aim of this study was to determine whether interferon combined with surgical excision and fulguration could reduce the unacceptably high rate of recurrence of anal condyloma seen after surgical extirpation. METHODS: Forty-three patients with anal condyloma were prospectively randomized into two groups. Group I (n=25) patients underwent surgical excision and fulguration immediately followed by an injection of 500,000 IU (0.1 ml) of interferon alfa-n3 into each quadrant of the anal canal. Group II (n=18) patients underwent surgical excision and fulguration but then received four injections (0.1 ml) of saline into each quadrant of the anal canal. RESULTS: After a mean follow-up of 3.8 months, 10 of 43 (23 percent) patients developed recurrent anal condyloma. Only 3 of 25 (12 percent) interferon-treated patients had recurrences vs. 7 recurrences in 18 (39 percent) saline-treated patients (P=0.046). Interferon was particularly effective in reducing recurrences in patients whose condylomata were present for more than six months (P=0.04) and those condylomata that contained human papillomavirus DNA subtype 6/11 (P=0.05). CONCLUSION: Adjuvant interferon treatment can reduce the high recurrence rate of anal condyloma seen after surgical extirpation.Read at the meeting of The American Society of Colon and Rectal Surgeons, Chicago, Illinois, May 2 to 7, 1993.Winner of the Harry E.

Preoperative electrophysiologic assessment cannot predict continence after rectopexy

PURPOSE: The aim of this study was to evaluate preoperative electrophysiologic assessment for prediction of anal continence after rectopexy. METHODS: Forty-three patients with rectal prolapse (n=26) or internal rectal intussusception (n=17) underwent concentric-needle electromyography, fiber density determination by single-fiber electromyography of the external anal sphincter, and pudendal nerve terminal motor latency evaluation before Ripstein rectopexy. A detailed history was obtained from each patient preoperatively and postoperatively. RESULTS: Anal continence was improved after rectopexy, both in patients with rectal prolapse (P=0.06) and in those with internal rectal intussusception (P=0.003). Abnormal results were registered in one or several aspects of the electrophysiologic assessment in 31 (72 percent) of the patients. However, functional outcome with respect to continence was not predicted by preoperative electromyography or pudendal nerve terminal motor latency assessment results. CONCLUSION: Electrophysiologic examinations in the preoperative assessment of patients with rectal prolapse and internal rectal intussusception do not predict continence after the Ripstein rectopexy. The routine use of electrophysiologic assessment requires further definition.Supported by grants from the Kjell and Märta Beijer Foundation, the Marianne and Marcus Wallenberg Foundation, Karolinska Institute, and Bert von Kantzow's Research Foundation.Read at the XVII Biennial Congress of The International Society of University Colon and Rectal Surgeons, Malmö, Sweden, June 7 to 11, 1998.     

Delorme’s Procedure for Rectal Prolapse

PURPOSE: Clinical and physiological results of Delormes procedure were assessed retrospectively in patients undergoing this procedure for rectal prolapse. METHODS: A consecutive series of 31 patients (7 males, 24 females; age, 14–93, mean 70 years) with full-thickness, rectal prolapse were treated by Delormes procedure between 1994 and 2002. Median follow-up was 39 (range, 6–96) months. RESULTS: Good results were achieved in 27 patients (87 percent), prolapse recurrence was observed in 4 (13 percent), and mean recurrence time was 14 (range, 3–25) months. There were no postoperative deaths. Minor complications occurred in four patients. The median changes in preoperative and postoperative physiologic patterns in 16 patients were as follows: resting pressure from 21.0 (range, 5–48) to 23.5 (range, 12–76) cm H2O (P = 0.030), squeeze pressure from 64.0 (range, 27–248) to 108.0 (range, 32–264) cm H2O (P = 0.041), volume at first sensation from 100 (range, 70–180) to 70 (range, 40–130) ml (P = 0.002), maximum tolerated volume from 260 (range, 120–400) to 160 (range, 70–400) ml (P = 0.001). Incontinence improved in 63 percent. No patient became constipated, and 38 percent of those constipated preoperatively improved. The preoperative incontinence score improved from 11.5 (range, 1–20) to 6.0 (range, 0–20) after operation (P < 0.0001). CONCLUSION: Delormes procedure had a low morbidity, did not lead to constipation, improved anal continence, and had a reasonably low recurrence rate. Improved anal sphincter and rectal sensation were associated with a reduced incidence of defecatory problems after Delormes procedure.
