Between 1977 and 1987, 519 patients underwent operation for rectal carcinoma. Sixty-three patients underwent intersphincteric resection with direct coloanal anastomosis (CAA), and 77 had an abdominoperineal resection (APR). Curative surgery was achieved in 57 and 65 patients, respectively. Both groups were comparable regarding age, stage of tumors, and localization of tumors. During the mean period of 6.7 years (range: 3 to 13.6 years), all patients were examined according to a predefined follow-up plan. From those patients with curative surgery, 11% presented with pelvic recurrence and 33% with distant metastases after coloanal anastomosis; the rates of recurrence and distant metastases after APR were 17% and 35%, respectively. The corrected 5-year survival rates were 62% following CAA and 53% following APR. Eighty-five percent of the patients with CAA reported good functional results regarding anal continence. Our study demonstrates that the intersphincteric resection with CAA is a valuable surgical technique for rectal carcinoma with the benefit of preservation of continence. It is suitable for neoplasms with high- and medium-grade differentiation (G1 to G2) and a localization that allows a minimum distal clearence of 3 cm. 相似文献

OBJECTIVE: The authors' aim was to determine survival and recurrence rates in patients undergoing resection of rectal cancer achieved by abdominoperineal resection (APR), coloanal anastomosis (CAA), and anterior resection (AR) without adjuvant therapy. SUMMARY BACKGROUND DATA: The surgery of rectal cancer is controversial; so, too, is its adjuvant management. Questions such as preoperative versus postoperative radiation versus no radiation are key. An approach in which the entire mesorectum is excised has been proposed as yielding low recurrence rates. METHODS: Of 1423 patients with resected rectal cancers, 491 patients were excluded, leaving 932 with a primary adenocarcinoma of the rectum treated at Mayo. Eighty-six percent were resected for cure. Surgery plus adjuvant treatment was performed in 418, surgery alone in 514. These 514 patients are the subject of this review. Among the 514 patients who underwent surgery alone, APR was performed in 169, CAA in 19, AR in 272, and other procedures in 54. Eighty-seven percent of patients were operated on with curative intent. The mean follow-up was 5.6 years; follow-up was complete in 92%. APR and CAA were performed excising the envelope of rectal mesentery posteriorly and the supporting tissues laterally from the sacral promontory to the pelvic floor. AR was performed using an appropriately wide rectal mesentery resection technique if the tumor was high; if the tumor was in the middle or low rectum, all mesentery was resected. The mean distal margin achieved by AR was 3 +/- 2 cm. RESULTS: Mortality was 2% (12 of 514). Anastomotic leaks after AR occurred in 5% (16 of 291) and overall transient urinary retention in 15%. Eleven percent of patients had a wound infection (abdominal and perineal wound, 30-day, purulence, or cellulitis). The local recurrence and 5-year disease-free survival rates were 7% and 78%, respectively, after AR; 6% and 83%, respectively, after CAA; and 4% and 80%, respectively, after APR. Patients with stage III disease, had a 60% disease-free survival rate. CONCLUSIONS: Complete resection of the envelope of supporting tissues about the rectum during APR, CAA, and AR when tumors were low in the rectum is associated with low mortality, low morbidity, low local recurrence, and good 5-year survival rates. Appropriate "tumor-specific" mesorectal excision during AR when the tumor is high in the rectum is likewise consistent with a low rate of local recurrence and good long-term survival. However, the overall failure rate of 40% in stage III disease (which is independent of surgical technique) means that surgical approaches alone are not sufficient to achieve better long-term survival rates. 相似文献

Surgical treatment of lower rectal cancer with sphincter preservation using handsewn coloanal anastomosis 总被引:1,自引:0,他引:1

The present study was designed to evaluate the technical feasibility and oncologic results of performing handsewn coloanal
anastomosis (CAA). A total of 46 patients treated for lower rectal cancer using CAA were retrospectively studied, and the
oncologic results were compared with those of 105 patients treated with abdominoperineal resection (APR). CAA was performed
in patients who had both good mobility of the tumor and a distal clearance margin of more than 1.0 cm. No significant difference
was noted in the mortality rates following the two operations (CAA 2.2% vs APR 1.9%). Pelvic recurrence was detected in two
patients (4.5%) after CAA and in six patients (7.2%) after APR. The 5-year survival rate after CAA was 79.2% and that after
APR was 72.6%. No significant difference was noted in the incidence of pelvic recurrence or the survival rates between the
two operations. These results show that CAA could be an excellent reconstructive option in the treatment of lower rectal carcinoma
for selected patients. 相似文献

One hundred one patients with villous adenoma or invasive carcinoma of the distal rectum treated with local excision or coloanal anastomosis were studied. Twenty-three (45%) of the 51 patients with villous adenomas had transanal excision, another 23 (45%) had a posterior proctotomy, and five (10%) had a coloanal anastomosis. Only two patients with a villous adenoma developed a recurrence requiring repeat local excision. Fifteen (30%) of the 50 patients with invasive cancer were treated by transanal excision. All had tumors confined to the submucosa or superficial muscularis. Eighteen (85%) of 21 patients having posterior proctotomy also had tumors with similar depth of invasion. Six (43%) of the 14 patients having coloanal anastomosis had Dukes' B tumors, six (43%) were Dukes' C, and another two (14%) underwent palliative resection. The overall actuarial 5-year survival was 77%. Only four patients treated by transanal excision or posterior proctotomy died of metastatic disease. In the coloanal group, two of 12 patients undergoing curative resection died of recurrent cancer, and another has a pelvic recurrence. Villous adenomas of the distal rectum and selected carcinomas may be treated with local excision and coloanal anastomosis with preservation of sphincter function with good results. 相似文献

Background
Treatment of distal rectal cancer remains clinically challenging and includes proctectomy and coloanal anastomosis (CAA) or abdominoperineal resection (APR). The purpose of this study is to evaluate operative and pathologic factors associated with long-term survival and local recurrence outcomes in patients treated for distal rectal cancer.Methods
A retrospective consecutive cohort study of 304 patients treated for distal rectal cancer with radical resection from 1993 to 2003 was performed. Patients were grouped by procedure (CAA or APR). Demographic, pathologic, recurrence, and survival data were analyzed utilizing chi-square analysis for comparison of proportions. Survival analysis was performed using Kaplan–Meier method and log-rank test for univariate and Cox regression for multivariate comparison.Results
The median tumor distance from the anal verge was 2 cm [interquartile range (IQR) 0.5–4 cm]. Margins were negative in all but four patients (one distal, 0.3%; three radial, 1%). The 5-year overall survival rate was 82% (88.6% stage pI, 80.5% stage pII, 67.9% stage pIII). Older age, advanced pathologic stage, presence of lymphovascular or perineural invasion, earlier treatment period, and APR surgery type were associated with worse survival on multivariate analysis. The 5-year local recurrence rate was 5.3% after CAA and 7.9% after APR (p = 0.33).Conclusions
Low rates of local recurrence and good overall survival can be achieved after treatment of distal rectal cancer with stage-appropriate chemoradiation and proctectomy with CAA or APR. Sphincter preservation can be achieved even with distal margins less than 2 cm. 相似文献6.
The EEA-stapling device in anterior resection for carcinoma of the rectum. Technique and early recurrences 总被引:1,自引:0,他引:1
The EEA-autostapling device was used for the anastomosis in 34 patients operated upon with anterior resection for carcinoma of the rectum. The lower border of the tumours was located between 6 and 20 cm from the anal verge and the distal margin free of tumour in the resected specimen was 4 cm (1-8 cm). The anastomoses were within 10 cm from the anal verge in 27 patients. Technical problems occurred in two patients. Eight cases showed incomplete tissue rings but anastomotic leakage was noted merely in four patients (12%). Wound infections were rare (6%). According to Dukes' classification the material comprised 15% Dukes' A, 32% Dukes' B. 38% Dukes' C and 15% Dukes' D. The patients were followed with clinical examinations, rectal palpation and sigmoidoscopy every 3-6 months after the operation. Early local recurrence (median value 5 months) was diagnosed in seven patients (21%). They had in common tumour in the lower part of the rectum, extramural spread and a short distal margin free of tumour. Three of these were classified as Dukes' D, three as Dukes' C and one as Dukes' B. It is concluded that early local recurrence after anterior resection may be due to local tumour spread but a decreased circular radicality may be another reason. The results demonstrate the need to define patients who might be treated by an abdomino-perineal excision even if the EEA-stapler makes a low rectal anastomosis possible. 相似文献

BACKGROUND: No survival data have yet been published from the Kingdom of Saudi Arabia for patients with rectal cancer. The present paper reports experience with these patients over an 8-year period. METHODS: All patients referred to the King Faisal Specialist Hospital (KFSH) between March 1990 and February 1998 for the primary management of rectal cancer were entered into a computerized database. Prior to 1993 patients did not receive adjuvant therapy. Kaplan-Meier survival curves and the log-rank test were used to compare outcome data. RESULTS: There were 70 men (average age: 55.6 years) and 75 women (average age: 52.8 years). Twelve per cent of patients admitted a family history of colorectal carcinoma (CRC). Twenty-seven per cent of tumours were circumferential. Most tumours were larger than 4 cm and the lowest edge of the majority of tumours was less than 6 cm from the anal verge. Fifty-four per cent of tumours were fixed; 69% of patients received either pre-operative or postoperative radiotherapy. A total of 106 patients underwent 'curative' surgery. Equal numbers of patients had abdomino-perineal resection (APR) and anterior resection (AR) of the rectum. Thirty-five patients received blood peri-operatively (APR, 34%; AR, 12%). Major anastomotic leakage following AR occurred in two patients. Two patients died within 30 days of surgery. Ten patients were lost to follow-up. Following curative AR, eight patients had a distal resection margin of < 2 cm and two patients (Dukes' C) developed local recurrence (25%); 37 patients had a margin > 2 cm and seven developed local recurrence (18.9%). A total of 48 patients underwent curative APR, and four patients developed local recurrence (8.3%). Overall local recurrence was tumour stage-dependent (Dukes' B, 8.8%; Dukes' C, 29.3%). Recurrence was local in 13 patients. Pre-operative radiotherapy seemed to reduce average tumour size (3.6 vs 4.3 cm). The crude overall 5-year survival rate was 39%. The 5-year survival rate for patients with Dukes' stage C cancers following 'curative' surgery was 25%. CONCLUSION: Curative surgery can be performed with a relatively low requirement for blood transfusion, a low mortality and morbidity, and comparable outcomes to Western studies in spite of the large, low and often advanced stage of the tumours managed. Local recurrence rates following curative resection and re-anastomosis for low rectal cancers may be reduced by resisting patient pressure to avoid stomata. 相似文献

The aim of this study was to determine the efficacy and long term results of straight colo-anal anastomosis (CAA) after resection for rectal carcinoma as described by Parks. From January 1986 to June 1989, 40 patients underwent this operation: 27 men and 13 women with a mean age of 63.5 years (range 37-81). In 36 cases, the indication was for carcinoma of mid and low rectum and in 4 cases for carcinoma of the upper rectum associated with a low rectal benign tumour (3 Dukes A, 19 Dukes B, 13 Dukes C, and 5 Dukes D). A diverting colostomy was constructed in all cases. Operative mortality was one patient (2.5 per cent) by pulmonary embolism. Anastomotic dehiscence occurred in four patients. None of these patients required reoperation and all colostomies have been closed. 6 patients presented a local recurrence (15.4 per cent) 6 to 34 months after CAA, of whom two were treated by abdomino-perineal resection. 5 patients died 6 to 34 months after CAA from local recurrence (2 cases) or distant metastasis (3 cases) and one patient has liver disease. All others patients are alive free of disease with a mean follow-up of 21.7 months (range 3-46 months). Actuarial survival is 77 per cent at 40 months. Functional results were assessed in the 26 patients followed up more than one year. The mean stool frequency was 2.4 per day (range 0, 3-6). All patients are continent, with a good discrimination gas-stool. 4 patients (15.4 per cent) suffer from soiling, 5 (19 per cent) from stool frequency, and 2 (7.7 per cent) from urgency. In conclusion, CAA is a good alternative of abdominoperineal resection for some mid and low rectal carcinomas. Functional results might be improved by the construction of a colonic reservoir. 相似文献

From 1966 to 1981, 646 patients underwent resection for primary adenocarcinoma of the rectum by one surgeon (S.A.L.) in one hospital. The operation, selected by preoperative sigmoidoscopic measurement, was anterior resection (ASR) in 320 patients, abdominosacral resection (ASR) in 175 patients, and abdominoperineal resection (APR) in 151 patients. The operative mortality rate was 2% following each of the operations. Anastomotic complications occurred in less than 2% after AR and in 9.7% after ASR. All patients were completely continent of stool and flatus after AR and ASR. Follow-up is complete in 419 of 427 patients treated from 1966 to 1976. Five-year survival for curative resection (no distant metastases) was 66.2% after AR (129/195), 62.9% after ASR (56/89), and 43.4% after APR (33/76). For patients with no tumor in lymph nodes, survival rates were 73.9% in AR, 75% for ASR, and 59.5% for APR. With involvement of regional lymph nodes, survival fell to 45.2% in AR, 37.9% for ASR, and 17.7% for APR. Pelvic recurrence was detected in 13.3% after AR, 14.6% after ASR, and 13.2% after APR. The authors believe that for midrectal cancer, ASR is the most reliable sphincter-saving procedure. It affords maximum exposure for wide resection of the tumor and safe anastomosis without disrupting the anal sphincters and their innervation. Sphincter preservation can be consistently preserved with no apparent increase in the risk of local recurrence or death from cancer. 相似文献

Comparison of colonic J-pouch reconstruction and straight coloanal anastomosis after intersphincteric rectal resection 总被引:7,自引:1,他引:7

The tendency towards sphincter-preserving resection for distal rectal cancers has led to the technique of straight coloanal anastomosis (CAA) and colonic J-pouch anal anastomosis (CPA) after low anterior resection. The aim of the present study was to compare complication rate, anorectal physiology and functional results after both types of reconstruction after ultra-low intersphincteric resection. A total of 31 patients who had undergone CPA were followed up prospectively using anorectal manometry and a standardised questionnaire and were compared with 63 patients who had undergone CAA and were followed up in the same way. The complication rate after CPA did not differ significantly from that after CAA. One year postoperatively, the median stool frequency and urgency were reduced after CPA (1.7+/-2.2/day; 7% vs. 2.4+/-3.6/day; 14%; P<0.05). Three months after colostomy/ileostomy closure, the maximum tolerable volume, threshold volume and compliance were decreased after CAA when compared with CPA (55+/-12, 34+/-12, and 3.9+/-0.3 ml/mmHg vs. 85+/-21, 53+/-11 and 6.2 ml/mmHg, respectively; P<0.05). Anal manometry revealed no significant differences in the anal resting and squeeze pressure. One year postoperatively, continence also did not differ significantly between CPA and CAA. Colonic J-pouch reconstruction seems to be superior to the straight coloanal anastomosis, especially during the first postoperative year. In view of the often poor prognosis of the patients, it is the reconstruction of choice after ultra-low resections of the rectum. 相似文献

Aim A permanent colostomy is considered to have an adverse impact on quality of life (QOL). However, functional outcomes following sphincter preservation also affect QOL. Our aim was to determine differences in QOL of patients undergoing coloanal anastomosis (CAA) or abdominoperineal resection (APR) for distal rectal cancer. Method Eighty‐five patients underwent CAA (72 with intestinal continuity and 13 with a stoma because of complications) and 83 patients underwent APR for a distal rectal cancer between 1995 and 2001 at a single institution and responded to our survey. QOL was evaluated using the EORTC QLQ‐C30 and QLQ‐CR38. Results Patients with CAA were younger than APR patients (mean age 57 vs 62 years, P < 0.001), but gender distribution, tumour stage and proportion of subjects receiving radiotherapy was not significantly different. Patients undergoing CAA had higher scores (better QOL) for physical functioning; lower scores (fewer symptoms) for fatigue, pain, financial difficulties, weight loss and chemotherapy side effects; and higher scores (more symptoms) for constipation and gastrointestinal symptoms compared with APR patients. CAA patients had higher scores (better QOL) for body image in men but not in women. Sexual functioning scores in men and women were lower (worse QOL) in CAA patients compared with APR patients. Conclusions QOL after APR is comparable to sphincter preservation, although there are some differences that need to be considered. QOL and functional results should be taken into account with the oncological outcome when devising management strategy for distal rectal cancer. 相似文献

Local recurrence after radical surgery for colorectal cancer 总被引:1,自引:0,他引:1

Local recurrence of colorectal cancer after curative surgery is a major clinical problem. The aim of our study was to present our experience in this field. Between January 1990 and December 2000, 572 patients underwent resection for colorectal cancer in our department; 66 of them had local recurrence within the first 2 years. Most of those patients had Dukes' stage B (n = 24) or stage C (n = 37) tumors, which were located mainly in the rectum (n = 40) and sigmoid colon (n = 18). The incidence of local recurrence was 11% and 15.9% for tumors that were Dukes' stages B and C, respectively. Thirty-five of 66 patients received palliative treatment, and 28 of them died within 9 months. The remaining 31 patients underwent radical excision of the recurrent tumor: 11 of these patients died within 2 years, and 20 were still alive after 30 months. The only hope for long-term survival for patients presenting with local recurrence from colorectal cancer after primary radical treatment is to identify local recurrence at an early stage and treat it in a radical manner. 相似文献

OBJECTIVE: Our institution's experience with low anterior resection in combination with coloanal anastomosis (LAR/CAA) for primary rectal cancer was reviewed (1) to determine cancer treatment results, 2) to identify risk factors for pelvic recurrence, and 3) to assess the long-term success of sphincter preservation. SUMMARY BACKGROUND DATA: Use of sphincter-preserving resection for mid-rectal and selected distal-rectal cancers continues to increase. As surgical techniques and adjuvant therapy evolve, treatment results must be carefully assessed. METHODS: One hundred thirty-four patients treated for primary rectal cancer by LAR/CAA between 1977 and 1990 were studied retrospectively. All pathologic slides were reviewed. Median follow-up was 4 years. RESULTS: Actuarial 5-year survival for all patients was 73%. Among 36 patients who relapsed, distant metastatic disease had developed at the time of first clinical relapse in most (86%). Pelvic recurrence was detected in 13 patients, an actuarial rate of 11% at 5 years. Mesenteric implants, positive microscopic resection margin, T3 tumor, perineural invasion, blood vessel invasion, and high tumor grade were associated with increased risk for pelvic recurrence. Eleven patients ultimately required permanent colostomy, and in eight instances the cause was pelvic recurrence. CONCLUSIONS: Low anterior resection combined with coloanal anastomosis provides good treatment for mid-rectal cancers and for some distal rectal cancers. Pelvic recurrence is not associated with short distal resection margins but is correlated with the presence of histopathologic markers of aggressive disease in the primary tumor. Long-term preservation of anal sphincter function depends primarily on control of pelvic tumor and can be achieved in more than 90% of patients. 相似文献

Anastomotic leakage after curative anterior resection results in a higher prevalence of local recurrence 总被引:17,自引:0,他引:17

BACKGROUND: The aim of this study was to determine whether leakage from a colorectal anastomosis following potentially curative anterior resection for rectal cancer is an independent risk factor for local recurrence. METHODS: The study included all patients who had a potentially curative anterior resection with anastomosis for adenocarcinoma of the rectum between 1971 and 1991 at Concord Hospital. The data were collected prospectively, with complete follow-up for at least 5 years. The Kaplan-Meier method was used to compare time to recurrence between strata of categorical variables. Proportional hazards regression was used in multivariate modelling. RESULTS: There were 403 patients in the study. After adjustment for lymph node metastases, the distal resection margin of resection, non-total anatomical dissection of the rectum and the level of anastomosis, multivariate analysis identified a significant association between anastomotic leakage and local recurrence (hazard ratio 3.8, 95 per cent confidence interval 1.8 to 7.9). CONCLUSION: Leakage following a colorectal anastomosis after potentially curative resection for adenocarcinoma of the rectum is an independent predictor of local recurrence. 相似文献

Oncological outcome of ultra-low coloanal anastomosis with and without intersphincteric resection for low rectal adenocarcinoma 总被引:5,自引:0,他引:5

BACKGROUND: The value of ultra-low coloanal anastomosis (CAA) for rectal cancer is dependent on the oncological and functional results. The aim of this comparative study was to evaluate the long-term oncological outcome of CAA with or without intersphincteric resection (ISR) for low-lying rectal tumours. METHODS: The study population comprised consecutive patients with low rectal cancer who underwent CAA in a single institution between 1977 and 2004. Patients were divided into two groups according to whether or not a partial ISR had been performed. Cox multivariate models were used for survival analysis. RESULTS: Some 278 patients underwent CAA with curative intent; 173 had ISR and 105 had CAA without ISR. Mean follow-up was 66.8 months. The 5-year actuarial rate for local recurrence, regardless of tumour stage, was 10.6 per cent in the ISR group versus 6.7 per cent for CAA alone (P = 0.405), and the 5-year actuarial overall survival rate was 86.1 and 80.0 per cent respectively (P = 0.318). Cox multivariable analysis revealed that resection of the anal canal was not a prognostic factor for local or metastatic recurrence. CONCLUSION: Sphincter-preserving surgery appears to be oncologically adequate for very low-lying rectal tumours. 相似文献

One hundred patients with rectal cancer treated by one surgeon over a 7 year period are reviewed. Fifty-five patients were treated by stapled anterior resection (SAR) and 45 by abdominoperineal resection (APR). Dukes' classification, degree of differentiation and local spread were similar in both groups. Operative mortality was 7.2 per cent for SAR and 2.2 per cent for APR. Anastomotic leakage following SAR occurred clinically in two patients (3.6 per cent), one of which proved fatal, and radiologically in five patients. Morbidity after SAR and APR was otherwise similar. There was no significant difference in local recurrence rates after SAR (14.7 per cent) and APR groups (25.0 per cent). The results of this study suggest that for patients with rectal cancer radical excision with sphincter presentation using the circular stapler has a mortality, morbidity and risk of local recurrence comparable with radical excision with a permanent colostomy. 相似文献

Carcinoma of the rectum: a 10-year experience 总被引:19,自引:0,他引:19
A consecutive series of 303 patients with carcinoma of the rectum and distal sigmoid colon treated by a single surgeon over a 10-year period are reported. Of these, 202 underwent an anterior resection, 85 an abdominoperineal excision of the rectum and 16 a coloanal anastomosis. Surgery was considered palliative in 52 patients undergoing anterior resection and 24 undergoing abdominoperineal resection. The 30-day hospital mortality rate was six patients (3 per cent) for anterior resection and two patients (2 per cent) for abdominoperineal resection. Peroperative anastomotic testing demonstrated leakage in five stapled anastomoses; these were rectified and no clinical sequelae occurred. Two patients (1 per cent) developed a clinical anastomotic leak, one of which proved fatal; in each case the intraoperative test was negative. The overall 5-year survival rate was 64 per cent after anterior resection and 52 per cent after abdominoperineal resection; the median follow-up was 64 months. The incidence of local pelvic recurrence was 6.4 per cent after anterior resection and 14 per cent after abdominoperineal (not significant). These results confirm the success of sphincter-saving anterior resection combined with total mesorectal excision, routine full mobilization of the splenic flexure and cancercidal lavage of the distal rectum in the treatment of low rectal carcinomas; morbidity, local recurrence and survival are not compromised. 相似文献

The surgical procedure is a crucial factor in preventing local recurrence in rectal cancer, and total mesorectal excision (TME) particularly is widely accepted as being associated with a decreased local recurrence rate. In this study, concerning 187 patients with rectal cancer, we compare conventional surgery, performed in 140 patients from 1979 to 1993, with a standardised TME procedure in 47 patients over the period from 1994 to 1998. The first group not treated by TME were operated on for 56 (40%) tumours of the upper rectum and 84 (60%) of the lower rectum; 35 (25%) were Dukes' A, 77 Dukes' B and 28 (20%) Dukes' C. 42 abdominoperineal amputations (30%) and 98 anterior resections (70%) were performed. The second group in which TME was performed comprised 17 (36%) tumours of the upper rectum and 30 (64%) of the lower rectum, 8 (17%) in stage I AJCC (Dukes' A), 16 (34%) in II (B) and 23 (49%) in III (C). 9 abdominoperineal amputations (19%) and 38 anterior resections (81%) were performed, 8 (21%) with an ultra-low anastomosis. In the first group of patients we observed 28 local recurrences (20%) and a 5-year disease-free survival in 50% of cases. In the second group we achieved a decreased rate of local recurrence (10.6%) which is about half that observed after conventional surgery, but there was no significant difference in survival. These data confirm the effectiveness of TME in reducing local recurrence rate, according to the literature; in future this procedure can get to reconsider the role of adjuvant therapy in the management of rectal cancer. 相似文献

Impact of total mesorectal excision on the results of surgery of distal rectal cancer. 总被引:18,自引:0,他引:18
BACKGROUND: This study reviewed the results of surgery for distal rectal cancer (tumours within 6 cm of the anal verge) following the introduction of total mesorectal excision for rectal cancer in one institution. METHODS: Two hundred and five patients who had undergone surgical resection of rectal cancer within 6 cm of the anal verge were included. The demographic, operative and follow-up data were collected prospectively. Comparisons were made between patients who had different surgical procedures. RESULTS: Abdominoperineal resection (APR) was performed in 27.8 per cent of patients, falling from 36.0 per cent in the first 3 years to 20.0 per cent in the last 3 years of the study. The overall operative mortality rate was 1.5 per cent and the morbidity rate 30.2 per cent. With a mean follow-up of 36 months, local recurrence occurred in 28 of the 185 patients who had curative resection. The 5-year actuarial local recurrence rates for double-stapled anastomosis, peranal coloanal anastomosis and APR were 11.2, 34.6 and 23.5 per cent respectively. The local recurrence rate was significantly lower for double-stapled low anterior resection than for the other types of operation. The overall 5-year survival rate in patients with low anterior resection and APR was 69.1 and 51.1 per cent respectively (P = 0.12). CONCLUSION: With the practice of total mesorectal excision, APR was necessary in only 27.8 per cent of patients with rectal cancer within 6 cm of the anal verge. The local recurrence rate was much lower in patients with double-stapled low anterior resection than in those treated with APR or peranal anastomosis. 相似文献

STUDY AIM: This retrospective study was designed to assess the operative, oncologic and functional results of total proctectomy with coloanal anastomosis (CAA). PATIENTS AND METHOD: Between 1990 and 1994, 81 patients (44 males/37 females: mean age: 59 years) were operated for a cancer (n = 67) or a benign lesion (n = 14) of the rectum. Sixty-four patients had a straight CAA and 17 patients had a colonic J-pouch. RESULTS: There was no operative mortality. Two patients were reoperated for colonic necrosis and underwent abdominoperineal resection. An anastomotic leak was observed in 11 patients and its severity was decreased by a diverting stoma. An anastomotic stricture was observed in 10 patients. Of the 67 patients with cancer, 19 (28%) developed metastases and 11 (16%) developed local recurrence. The 5-year survival rate was 69%. Twelve months after the operation, continence was similar with the two types of CAA, but the mean daily stool frequency was lower in patients with a reservoir. With a long follow-up (mean = 9 years), functional results were good with regard to continence and stool frequency, almost similar with the two types of CAA; functional disorders (noctumal stools, fragmentation, urgency) were reported by 25 to 40% of patients. CONCLUSION: Total proctectomy with coloanal anastomosis yields good oncologic results. With regard to functional results, the superiority of the colonic J-pouch, which is observed in the first postoperative year, was lost beyond this period; long-term results are good for continence and stool frequency, but some disorders persist in a significant proportion of patients. 相似文献
