Acute abdomen due to J-pouch outlet obstruction: A case report and review of literature

IntroductionIleal pouch–anal anastomosis is the procedure of choice for re-establishing intestinal continuity for patients undergoing total proctocolectomy. Despite growing experience with this procedure, it is still associated with considerable morbidity rates.Presentation of caseHerein, we report the case of a 14-year-old boy with familial adenomatous polyposis who underwent total proctocolectomy, ileal pouch–anal anastomosis, and diverting ileostomy. The patient developed early postoperative complications; on postoperative day 1, he developed bleeding from the pouch staple line, which was managed endoscopically. On postoperative day 15, he developed intestinal obstruction due to adhesions. One year after proctocolectomy, ileostomy closure was performed uneventfully. From postoperative day 3, the patient presented with obstructive signs such as abdominal distention, bloating, abdominal pain, and fever. Computed tomography identified diffuse intense intestinal distension with pouch dilatation. Digital rectal examination identified the pouch filled with liquid stool and no signs of anal canal anastomosis stenosis. The patient was considered to have pouch outlet obstruction and was successfully managed using bedside evacuation anoscopy. After 3 days, oral nutrition was re-established, and appropriate stool evacuation and fecal continence were achieved.DiscussionProctocolectomy with ileal pouch–anal anastomosis still carries a considerable complication rate. Proper identification of causative factors is mandatory for appropriate treatment. Pouch outlet obstruction can present as acute abdomen after diverting ileostomy closure. In this case, outlet obstruction was identified and treated by pouch evacuation, avoiding morbidity of a new surgical procedure.ConclusionWe presented an unusual case of acute intestinal obstruction due to pouch outlet obstruction that was managed nonoperatively with bedside pouch evacuation.     

Anorectal manometry and ileo-anal anastomosis]

Seventeen patients (12 ulcerative colitis, 5 familial adenomatous polyposis) underwent proctocolectomy and ileal J pouch anastomosis. Anal manometry with determination of maximum tolerable volume and a liquid continence test were perform before ileo-anal anastomosis, before closure of the loop ileostomy and 12 months after closure of the loop ileostomy. All patients were continent during the daytime less 12 months after proctocolectomy. The mean stool frequency was 5 stools per day in our 17 patients. A significant increase in maximum tolerable volume and in the liquid continence test was observed during the first year after closure of the ileostomy. Anal manometry is unnecessary after ileoanal anastomosis, but preoperatively, this test is able to exclude some patients with low anal pressure.     

Restorative proctocolectomy with and without protective ileostomy in a pediatric population

Purpose

This study aim was to review outcomes of pediatric patients after restorative proctocolectomy with or without a protective ileostomy in the treatment of ulcerative colitis and polyposis syndromes.

Methods

All patients who underwent rectal mucosectomy with ileal pouch reservoir and hand-sewn ileal pouch anal anastomosis (IPAA) during 19-year period were reviewed retrospectively.

Results

Eighty-three patients with ulcerative colitis and 7 patients with polyposis syndromes (ages 2.0-21.8 years) were reviewed. Sixty-eight patients underwent IPAA without diverting ileostomy. Fifty-six patients underwent restorative proctocolectomy as single-stage procedures, and 12 had abdominal colectomy and subsequent definitive IPAA without diverting ileostomy. Nineteen patients had IPAA with diverting ileostomy and subsequent closure of ileostomy. Three-stage procedures were performed in 3 cases. An ileal pouch leak or pelvic abscess occurred in 2 patients. Surgical pouch revision for retraction, efferent limb syndrome, prolapse, pouchitis, or perirectal infections occurred in 19 (6/62 J-pouch, 13/28 S-pouch). Fourteen patients (5/22 with diversion, 9/68 without diversion) developed small bowel obstruction. Overall, daytime and nighttime continence was excellent with rare nocturnal evacuations.

Conclusions

Restorative proctocolectomy without protective ileostomy is not associated with an increased morbidity, even in patients with active colitis, and may be appropriate most patients.     

Changes in Intestinal Transit Time after Proctocolectomy Assessed by the Lactulose Breath Test

After proctocolectomy with ileal pouch-anal anastomosis (IPAA) patients have increased stool frequency and intermittently use antidiarrheal medication. In addition to other factors, gastrointestinal transit time (MTT) could influence stool frequency. The aim of this study was to investigate how MTT changes after IPAA and to study whether MTT has an influence on daily stool frequency. In a prospective trial MTT was investigated with the lactulose breath test in 12 patients undergoing surgery for chronic ulcerative colitis (CUC) or familial adenomatous polyposis coli (FAPC) at different stages: before proctocolectomy, after IPAA with loop ileostomy, and 3 months and 1 year after ileostomy closure. MTT was also measured in 12 patients with IPAA, 12 patients with subtotal colectomy and ileorectal anastomosis (IRA), and 8 patients with conventional proctocolectomy and Brooke ileostomy (CPC) several years after surgery. Twelve healthy volunteers served as controls. Before IPAA, MTT was prolonged in CUC versus FAPC and controls. After restoration of gut continuity MTT was markedly accelerated. After 1 year MTT was slowed again, though values before proctocolectomy and those in controls were not reached. Several years after surgery MTT was significantly prolonged in IPAA and IRA versus controls. In CPC, MTT could not be determined by lactulose breath test. Stool frequency showed an inverse correlation to MTT in IPAA. In conclusion, this study shows that orocecal and oropouch transit are accelerated in the early postoperative period after (procto)colectomy but prolonged in the long-term course. Adaptation of the small bowel takes longer than 1 year. Impairment of stool frequency may be partly due to this adaptation.     

Quadruple-loop (W) ileal pouch reconstruction after proctocolectomy: analysis and functional results

This report analyzes experience with a modified four-limb W-shaped ileal pouch that has a larger initial capacity than do J- or S-shaped pouch designs. Fifteen patients (median age: 35 years) underwent W pouch reconstruction after proctocolectomy for ulcerative colitis and familial adenomatous polyposis. Follow-up on each patient averaged 14 months (range: 6 to 24 months). All procedures were performed without death and with minimal morbidity. Assessment of functional results showed 24-hour stool frequency (mean +/- SEM) decreasing from 6.0 +/- 0.39 initially to 4.8 +/- 0.43 at 1 year (p less than 0.005). Night evacuation decreased from 1.1 +/- 0.2 at 1 month after surgery to 0.25 +/- 0.12 at 1 year (p less than 0.025), with 10 of 15 patients having no nocturnal pouch evacuation. Continence was excellent in all patients with the exception of three of 15 patients who had occasional minimal nighttime seepage. Pouch volume determined at surgery by saline solution infusion was 200 +/- 21 ml. Pouch volume and compliance (pressure/volume) were measured before ileostomy closure and at 6 months after surgery via a special pressure-monitored balloon catheter. Maximal pouch volume increased from 190 +/- 21 ml (at time of ileostomy takedown) to 470 +/- 85 ml at 6 months. Ileal reservoir construction with a W pouch design resulted in a low 24-hour and nighttime stool frequency and excellent compliance and evacuation characteristics.     

Filling Sensations after Restorative Proctocolectomy

Objective : in order to improve insights in rectal filling sensation, we studied pouch filling sensations after ileal J pouch-anal anastomosis (IPAA) before and after re-establishment of bowel continuity.

Methods : anal manometry and a pouch filling sensation test were performed before as well as 1 and 6 weeks after closure of the loop ileostomy in 17 patients who had undergone restorative proctocolectomy with stapled (8 patients) or manual pouch-anal anastomosis (9 patients). The results were compared with those of 12 control subjects. Results : before ileostomy closure, pouch pressure necessary for inducing the respective sensation thresholds was higher than in controls; the difference was significant for constant and urge sensation. The volumes for urge and maximum tolerable sensation level were significantly lower, with reduced pouch compliance. After stoma closure, pressure and volume thresholds at all sensation levels became completely comparable with control data. No relevant differences were observed between stapled and manual ileal pouch-anal anastomoses.

Conclusions : all levels of filling sensation levels are preserved after restorative proctocolectomy and their parameters are comparable with those of normal rectal filling sensation. Diversion of an ileal J pouch results in resetting of filling sensation thresholds towards lower volume and higher pressure values, but all sensation thresholds normalize within 6 weeks after stoma closure. These data document that neither the rectum, nor the mucosa of the anorectal junction and upper part of the anal canal are involved in filling and urge sensation.     

The use of an ileostomy connector to diminish the frequency of defecation prior to ileostomy closure in patients with a pelvic pouch

A new method for allowing stool passage into the pelvic pouch before ileostomy closure to verify the defecation state and diminish stool frequency is reported herein. This was accomplished by fitting an ileostomy connector connecting the proximal and distal openings of the diverting loop stoma. The ileostomy connector was initially in place for 6 h a day, the length of time being gradually increased until it was able to be left in for 24 h a day over a 3-month period. The calculated daily frequency of stools decreased from 24 to 6 or 7 times, and the mean daily frequency immediately after ileostomy closure was 6.5 times. Physiological study also showed an improvement, with squeeze pressure increasing from 35 cmH₂O to 116 cmH₂O and the maximum tolerated volume increasing from 35 ml before, to 90 ml 3 months following the use of an ileostomy connector. Thus, we conclude that an ileostomy connector may be useful to predict postoperative functional outcome and its complications, and to diminish the frequency of defecation before ileostomy closure in patients with a covering loop stoma.This study was submitted as a poster presentation at the meeting of the XIVth Biennial Congress of the University of Colon and Rectal Surgeons in Creta, Greece, October 25–29, 1992.     

Anal and ileal pouch manometric measurements before ileostomy closure are related to functional outcome after ileal pouch-anal anastomosis

Anal canal length, and canal resting and squeeze pressures, ileal pouch capacity and pouch compliance were measured in 104 patients after ileal pouch-anal anastomosis but before ileostomy closure. The intention was to determine if such parameters were associated with late functional outcome after re-establishment of intestinal continuity. Functional outcome in terms of stool frequency (day and night), incontinence (day and night), perianal pad use, perianal skin irritation, and the use of constipating agents was assessed for all 104 patients 1 year or more (median 438 days) after ileostomy closure. A low mean anal sphincter resting pressure before ileostomy closure was associated with subsequent nocturnal incontinence (P less than 0.05) and, to a lesser extent, the need to use constipating agents (P = 0.08). Pouch compliance if low before ileostomy closure was associated with an increased frequency of nocturnal stool frequency after 1 year (P less than 0.05). Anal canal length, and sphincter squeeze pressure and pouch capacity before ileostomy closure were not related to subsequent functional outcome in these patients.     

Stapled ileoanal anastomosis for ulcerative colitis and familial polyposis without a temporary diverting ileostomy.

Between March 1989 and August 1990, we performed 21 stapled J pouch ileonal procedures (20 ulcerative colitis [UC], 1 familial polyposis [FP]) without an ileostomy in 19, of whom 13 were taking prednisone and eight underwent semi-emergent surgery for uncontrollable bleeding. During the same time, an additional four patients required a standard ileonal procedure. The results of anal manometry and clinical function were compared to 25 patients who had previously undergone mucosal stripping and a sutured J pouch ileoanal anastomoses with a temporary diverting ileostomy between October 1982 and August 1990. During this same time period, an additional 19 patients underwent an anti-peristaltic reversed J pouch and 18 an S pouch, for a total of 83 ileoanal procedures. The reversed J pouch had a lower stool frequency than a standard J pouch but had an unacceptable incidence of complications and problems with pouch emptying. The S pouch had a stool frequency similar to the standard J pouch but provided greater length in patients with a short mesentery. Stapled J pouch ileoanal patients had a better (p less than 0.02) maximum and sphincter resting pressure (46 +/- 11 versus 34 +/- 12 mmHg), fewer (p less than 0.05) night-time accidents (22% versus 68%), daytime (17% versus 55%) or night-time (28 versus 61%) spotting, or use of a protective pad at night (11% versus 42%) than nonstapled J pouch ileoanal patients. Stool frequency was similar in the two groups. All but one UC patient had residual disease at the anastomosis. Anal mucosa between the dentate line and stapled anastomosis was 1.8 +/- 1.3 cm (range, 0 to 3.5 cm). Complications in the nonstapled J pouch group included 4 pouches excised (2 for complications, 2 for excessive stool frequency), 1 pelvic abscess, 2 stenosis requiring dilation under anesthesia, 1 enterocutaneous fistula after ileostomy closure, 1 ileostomy site hernia, and 2 small bowel obstructions. Of the 65 patients who underwent ileostomy closure in the entire series, 8 (12%) developed a complication requiring surgical intervention. Complications in the stapled group included 1 anastomotic leak, 1 pouch leak, and 1 pelvic abscess. Patients were managed successfully with drainage (all 3) and diverting ileostomy (1). One patient developed stenosis requiring dilation under anesthesia. The stapled J pouch ileoanal anastomosis is a simpler, safer procedure with less tension than a standard handsewn J pouch but leaves a very small cuff of residual disease. It provides significantly better stool control and may obviate the need for an ileostomy with its complications.     

Holmium: yttrium aluminium garnet laser lithotripsy for symptomatic Kock pouch calculi

Kock first described continent ileostomy for fecal diversion in 1969 as an alternative procedure to conventional ileostomy. Later, this procedure was replaced by restorative proctocolectomy with ileal pouch anal anastomosis as the procedure of choice. The main reasons for its virtual abandonment include technical difficulty, high morbidity, and the need for a stoma. To our knowledge, this report is the first published case of successful enterolith destruction and retrieval from a Kock pouch, using a Holmium: yttrium aluminium garnet laser. This outpatient procedure can avoid the morbidity and cost of a laparotomy.     

HIGH DOSE LOPERAMIDE SUPPOSITORIES: A NOVEL APPROACH FOR IMPROVING CLINICAL FUNCTION AFTER RESTORATIVE PROCTOCOLECTOMY

The effect of loperamide suppositories on patients following restorative proctocolectomy was studied by means of a randomized, double-blind, crossover trial comparing active suppositories (20 mg b. d. X 1 week) with placebo. Ten patients (8 male, 2 female; 7 J pouch, 3 W pouch; 8 ulcerative colitis, 2 familial adenomatous polyposis) were studied 3–60 months (median, 31.5) after ileostomy closure. Ages ranged from 24 to 63 years (median, 41.5). All patients kept a diary of their bowel habits and eight underwent a standardized test of pouch compliance. Urgency volume (UV) and maximum tolerable volumes (MTV) and the volume at onset of large isolated pouch contractions (LIC) were recorded. Statistical analysis was by the Wilcoxon test for paired data. Mean daily stool frequency during the placebo phase ranged from 3.7 to 7.8. It was reduced during the active phase in only seven patients (P > 0.1) but was reduced in all six patients whose placebo phase stool frequency was five or more. Urgency volume was increased by use of active suppositories in six of the eight patients tested (P > 0.1). There was no consistent effect on MTV. Large isolated pouch contractions were not seen in either test in one patient. In all of the remaining seven patients LIC were recorded after the placebo phase. After the active phase LIC first appeared at higher volumes in three but were not seen at all in four patients. High dose loperamide suppositories suppress pouch contractions and tend to lower stool frequency especially when high initially. They represent a novel therapeutic approach to high stool frequency in pouch patients.     

Ileal pouch-anal anastomosis. The Emory University experience.

The ileal pouch-anal anastomosis has become a practical alternative to proctocolectomy for the treatment of ulcerative colitis and polyposis coli. To evaluate its success, the Emory University Affiliated Hospital experience from February 1984 to March 1989 was retrospectively reviewed. There were a total of 50 patients identified; 84 per cent had ulcerative colitis, and 16 per cent had polyposis coli (familial polyposis and Gardner's syndrome). The majority of these patients underwent a two-stage operation, but one-third required a three-stage procedure due to difficulty in mucosal proctectomy or toxic megacolon. J-pouch construction was performed in 72 per cent of patients, S-pouch construction in 14 per cent, straight ileo-anal anastomosis in 8 per cent, and lateral isoperistaltic ileo-anal anastomosis in 6 per cent. Of the 50 patients, 36 (72%) have had closure of the temporary ileostomy. Fourteen patients have not had ileostomy closure due to change in diagnosis to Crohn's disease, operative complications, or ileostomy closure pending. The combined operative morbidity per patient for the ileal pouch-anal anastomosis and the closure of the ileostomy was 32 per cent. This included bowel obstruction, 16 per cent; pelvic abscess, 6 per cent; and ileo-anal separation, 4 per cent. Follow-up on patients with ileostomy closure ranged from 6 months to 4 years (mean, 1.3 years). Stool frequency was 5.9 stools per 24 hours at 6 months and improved with time. During the follow-up period, all patients were eventually completely continent of stool during the day, and most became completely continent of stool at night.(ABSTRACT TRUNCATED AT 250 WORDS)     

Influence of ileal pouch capacity and anal sphincteric function on the clinical outcome after ileal pouch-anal anastomosis

This study was designed to determine the influence of ileal pouch capacity and anal sphincteric function on the clinical outcome after ileal pouch-anal anastomosis. A total of 24 patients who had undergone ileal pouch-anal anastomosis (J pouch) for ulcerative colitis were studied. The 24-hour stool frequency was found to be inversely correlated with the sensitivity threshold volume (STV), maximal tolerance volume (MTV), and distensibility, but was independent of the maximal resting pressure and maximal squeeze pressure. Patients experiencing nocturnal fecal incontinence had maximal resting pressures that were significantly lower than those of nocturnally continent patients. Among the patients with fecal incontinence, those with frequent soiling had lower resting pressures, STV, and distensibility than the patients with intermittent spotting. In addition, the STV in patients needing nocturnal evacuation were lower than those of patients who did not evacuate after falling asleep. The conclusions are as follows. Both stool frequency and the need for nocturnal pouch evacuation correlated directly with pouch volume. Anal incontinence was more common in patients with low internal sphincteric function. In addition, frequent and gross nocturnal incontinent patients demonstrate a worse function in both the anal sphincter and reservoir than those with intermittent spotting.     

Relationship between gastrointestinal transit time and daily stool frequency in patients after Ileal J pouch-anal anastomosis for ulcerative colitis

BACKGROUND: To investigate how the gastrointestinal transit function changes after ileal J pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) and to study whether gastrointestinal transit time (GTT) has an influence on daily stool frequency, we investigated the relationship between GTT and stool frequency per day. METHODS: Forty patients with UC who had undergone restorative proctocolectomy, with ileostomy closure at least 48 to 120 months (mean 96.3) previously, and who had no preoperative and postoperative complications were recruited. They were divided into two groups on the basis of their stool frequency: 26 patients had a stool frequency of less than 6 times per day (group A: 16 men, 10 women; aged 15 to 59 years old, average 36.6) and 14 patients had a stool frequency of 7 or more times per day (group B: 10 men, 4 women; 24 to 56 years old, average 40.9). The GTTs using a radiopaque marker were studied. Interviews concerning the defecation states were performed at the examination. RESULTS: High nocturnal stool frequency was significantly noted more in group B than in group A (P <0.001). All cases in group A and 12 cases in group B could discriminate flatus from feces, and there were significant differences between groups A and B (P <0.05). Feeling of stool remaining was significantly noted more in group B than in group A (P <0.01). Stool consistency in group A was harder than that in group B (P <0.001). Patients with soiling were significantly noted more in group B compared with those in group A (P <0.001). Incontinence was detected in only 2 cases in group B. Group A showed a better defecation state than group B. In the GTT study, the GTT was almost the same in groups A and B. The small bowel transit, pouch transit, and whole gut transit times in group B were faster than those of group A (P <0.001). Removal length of the terminal ileum in patients after IPAA: patients in group B (13.8 +/- 3.9 cm) had significantly more ileum removed compared with patients in group A (6.3 +/- 2.4 cm; P <0.001). Regression lines in the relationship between removal length of the terminal ileum and individual stool frequency showed there was a correlation between removal length of the terminal ileum and individual stool frequency per day in direct proportion (r = 0.79, P <0.001). A resection of more ileum, up to 15 cm, plays a role in increased stool frequency. CONCLUSIONS: The present results suggested that rapid transit of both the small bowel and pouch may lead to a high stool frequency of 7 or more times per day with a poor defecation state after IPAA. It was also pointed out in this study that an important point is a resection of more ileum, up to 15 cm, plays a role in increased stool frequency.     

Clinical and functional results after restorative proctocolectomy

Of 84 patients who underwent restorative proctocolectomy with an ileoanal reservoir in 21 Italian departments of surgery, 51 had ulcerative colitis, 32 familial polyposis and 1 intractable constipation. Follow-up information is available for all 58 patients who had their ileostomy closed, the length of follow-up ranging between 2 and 78 months. There were no operative deaths. A failure rate (i.e. excision of the pouch) of 3 per cent was observed. Sepsis was the most common postoperative complication, and was most often related to ileoanal anastomosis dehiscence (15 per cent), followed by small-bowel obstruction requiring laparotomy (10 per cent). Clinical 'pouchitis' occurred in 14 per cent of patients after ileostomy closure. The average frequency of defaecation was four motions per 24 h; evacuation was spontaneous in all patients and only 5 per cent complained of troublesome faecal soiling while 34 per cent had occasional incontinence to flatus and mucus. Patients with a short or absent rectal cuff had a lower rate of incontinence (30 versus 48 per cent, difference not statistically significant) without any increase in the frequency of genito-urinary disorders. None of the two most used reservoirs, the J (n = 40) and S pouch (n = 17) showed significant superiority in terms of bowel frequency and continence. Incontinence was more likely in patients whose ileostomy closure had been delayed for more than one year.     

Comparison of loop versus end ileostomy for fecal diversion after restorative proctocolectomy for ulcerative colitis

BACKGROUND: The goal of this study was to compare the benefits versus complications of temporary loop ileostomies and end ileostomies in a consecutive series of patients undergoing colectomy and ileal pouch-anal anastomosis for ulcerative colitis. STUDY DESIGN: A retrospective review was performed of all patients undergoing restorative proctocolectomy with diverting ileostomy for ulcerative colitis at the UCLA Medical Center during a 4-year period. An end ileostomy (EI) was used for 38 patients and a loop ileostomy (LI) for 39. All patients had a J pouch, with all EI patients having a hand-sewn ileoanal anastomosis, and 33 LI patients having a double-stapled anal anastomosis. EI closure was performed through a laparotomy, and LI closure was performed through a periileostomy incision. RESULTS: The mean operative time for EI closure was 157 minutes, and for LI closure was 103 minutes. The wound infection rate after EI closure was 5.3% and after LI was 10.3%. For EI patients, 2 of 38 patients required reoperation, compared with 5 of 39 for LI. The mean hospital stay after EI closure was 6.7 days, and after LI closure was 7.1 days. Peristomal skin irritation was more severe, more prolonged, and occurred in more than twice as many LI as EI patients. Home ostomy nurse care was necessary for a mean of two visits for EI patients and five visits for LI patients. The cost ofostomy supplies and care was more than double for LI patients compared with those with EI. Patient satisfaction and ability to resume physical and social activities early after ileostomy construction were much more favorable for EI than LI patients. CONCLUSIONS: The benefit of shorter operating time for LI closure compared with EI closure is often outweighed by the complications and costs of LI stomal care and patient dissatisfaction. EI should be considered more frequently for temporary ileal diversion after restorative proctocolectomy.     

Modified quadruple-loop (W) ileal reservoir for restorative proctocolectomy

Reconstructive ileal pouch procedures are well-accepted alternatives to a permanent ileostomy in select patients requiring proctocolectomy for ulcerative colitis and familial polyposis. Double-, triple-, and quadruple-loop and lateral isoperistaltic designs have been described; however, the ideal pouch capacity and configuration are still debatable. Evidence has been reported that improved functional results and lower stool frequency with less antidiarrheal medication can be achieved with larger volume reservoirs. We describe a new modification of a quadruple-loop pouch that has been successfully performed in 10 patients. This new approach to pouch construction produced excellent functional results 6 to 12 months after ileostomy takedown and was easier to construct and engage into the muscular cuff of the distal rectum than quadruple-loop pouches of equal length loops.     

Ileal pouch in the treatment of ulcerative rectocolitis and familial polyposis. Analysis of morbidity in a series of 30 cases

Between 1984 and 1989, 30 patients underwent total coloproctectomy with J ileal pouch and ileo-anal anastomosis. They corresponded to 29 cases of ulcerative colitis and one case of familial polyposis. The authors report their own experience and the related morbidity and functional results. There were 23% fistulae, 6.6% pouchitis, 10% stenoses, 8.7% pelvic abscesses, 10% bowel obstructions, 6.6% fistulae after ileostomy closure. Only one pouch had to be removed for severe pouchitis. Functional results were partly related to post-operative complications: 50% of patients had normal continence, 57% at least 6 stools per day, 81% had one stool per night, 15% had soiling. Morbidity is discussed for the various types of complications.     

Ileal "J" pouch-anal anastomosis. Clinical outcome.

One hundred eighty-eight patients undergoing abdominal colectomy with distal mucosal proctectomy and endorectal ileal pouch-anal anastomosis were reviewed to assess long-term functional results and to identify factors that might influence them. There was no postoperative mortality, but 10 patients (5.3%) required permanent ileostomy because of postoperative complications or the development of unsuspected Crohn's disease. Immediate postoperative complications, including pelvic sepsis, small bowel obstruction requiring surgery, anastomotic stricture, and ileostomy dysfunction, were observed in 11%, 9%, 14% and 9% of patients, respectively. No males were impotent but nine (9%) developed retrograde ejaculation. Pouchitis occurred in 8% of patients. Among 157 patients assessed at least 60 days after ileostomy closure (mean +/- SD, 375 +/- 216 days), all evacuated their neorectum spontaneously, and stool frequency was 6.0 +/- 2.6 daily and 1.2 +/- 1.3 nightly. While continence was generally good, 2.5% of patients during waking hours and 4.5% during sleep had occasional frank soilage. Moreover, seepage was noted in 25 and 47% of patients during daytime and nighttime, respectively. Both stool frequency and degree of continence improved with time. Patients less than 50 years of age and those with polyposis coli had fewer stools and better continence than those older than 50 or those with ulcerative colitis. It is concluded that ileal "J" pouch-anal anastomosis can be performed safely and will provide acceptable anorectal function without late deterioration.     

Results of 50 ileoanal J pouch operations

Fifty ileo-anal J pouches were constructed in 26 males and 24 females for ulcerative colitis (n = 45) and familial adenomatous polyposis (n = 5). Two-thirds had proctocolectomy and pouch formation as a one-stage procedure. Thirty patients had a handsewn pouch and anastomosis and 20 were stapled. Forty-five patients had their defunctioning ileostomy closed for at least 2 months, of whom three have not been recently reviewed. One pouch was defunctioned for ischaemic stricture. The median time between pouch construction and ileostomy closure was 15 weeks and the time between closure and assessment ranged from 2 to 50 months (median 18 months). Median stool frequency was six per 24h in both the handsewn and stapled groups. Faecal incontinence occurred in 20% of patients with a handsewn anastomosis but in no patient with a stapled anastomosis (P less than 0.02). Soiling was also more common in the former group. Some 76% of patients noted an improvement in pouch function with time. In all, 67% of males and 78% of females reported unchanged or increased sexual activity since pouch surgery. Pouchitis has occurred in 20% of patients; 10% have had complications related to the pouch or anastomosis; 10% related to the ileostomy; and 6% have had small bowel obstruction. There have been no deaths. Overall, 88% of patients have had a good result, but none of the five patients with a poor result will revert to an ileostomy.
