Luminal neutrophil migration in ileoanal pouches studied by whole gut lavage.

OBJECTIVE: White cell scintigraphy has shown that neutrophils migrate into the gut wall and lumen in ileoanal pouches. We aimed to establish whether whole gut lavage fluid can be used to investigate intestinal neutrophil migration in ileoanal pouches. DESIGN: A prospective single centre study recruiting consecutive patients. METHODS: Whole gut lavage with polyethylene glycol electrolyte solution was performed in 56 (32 men, 24 women) ileoanal pouch patients who had undergone colectomy for ulcerative colitis; the first clear effluent was collected, processed and stored at -70 degrees C. The fluid was assayed for neutrophil granulocyte elastase using a specific colorimetric assay, IgG, albumin, alpha1-antitrypsin, haemoglobin and cytokines IL-1beta and IL-8 using previously described techniques. Patients' disease activity was characterized following pouchoscopy and biopsy. RESULTS: Patients with pouchitis had significantly higher levels of granulocyte elastase in whole gut lavage fluid compared with those without pouchitis. Patients with detectable granulocyte elastase had higher pouchoscopy score, more severe mucosal neutrophil infiltration and protein loss and bleeding. These patients had significantly higher levels of cytokines IL-1beta and IL-8 in the whole gut lavage fluid, compared with patients with undetectable granulocyte elastase. CONCLUSION: Whole gut lavage fluid samples may provide a useful investigative tool to study mucosal inflammation and luminal neutrophil migration in ileoanal pouches.

A characterization of anaerobic colonization and associated mucosal adaptations in the undiseased ileal pouch.

INTRODUCTION: The resolution of pouchitis with metronidazole points to an anaerobic aetiology. Pouchitis is mainly seen in patients with ulcerative colitis pouches (UCP). We have recently found that sulphate reducing bacteria (SRB), a species of strict anaerobe, colonize UCP exclusively. Herein, we aimed to correlate levels of different bacterial species (including SRB) with mucosal inflammation and morphology. METHODS: Following ethical approval, fresh faecal samples and mucosal biopsies were taken from 9 patients with UCP and 5 patients with familial adenomatous polyposis pouches (FAPP). For the purposes of comparison, faecal samples and mucosal biopsies were also taken from the stomas of 7 of the 9 patients with UC (UCS). Colonization by four types of strict anaerobes (SRB, Clostridium perfringens, Bifidobacteria and Bacteroides) as well as by three types of facultative anaerobes (Enterococci, Coliforms and Lactobacilli) was evaluated. Inflammatory scores and mucosal morphology were assessed histologically in a blinded fashion by a pathologist. RESULTS: In general, strict anaerobes predominated over facultative in the UCP (P = 0.041). SRB were present in UCP exclusively. Even after exclusion of SRB from total bacterial counts, strict anaerobes still predominated. In the UCS, facultative anaerobes predominated. Strict and facultative anaerobes were present at similar levels in the FAPP. Enterococci were present at significantly reduced levels in the UCP when compared with the UCS (P = 0.031). When levels of SRB and other anaerobic species were individually correlated with mucosal inflammation and morphology, no trends were observed. CONCLUSION: We have previously identified that SRB exclusively colonize UCP. In addition we have now identified a novel increase in the strict/facultative anaerobic ratio within the UCP compared to UCS. These stark differences in bacterial colonization, however, appear to have limited impact on mucosal inflammation or morphology.

Endoscopic balloon dilation of ileal pouch strictures.

BACKGROUND: Restorative proctocolectomy with ileal pouch-anal anastomosis is the surgical treatment of choice in patients with ulcerative colitis. Strictures can occur at the inlet and outlet of the pouch. Endoscopic balloon dilation has been successfully used in patients with Crohn's strictures at the small intestine and colon. There are no published trials on endoscopic balloon therapy of ileal pouch strictures. AIM: To evaluate outpatient endoscopic balloon dilation of strictures in ileal pouches. METHODS: Patients underwent nonfluoroscopy-guided, nonsedated, outpatient endoscopic dilations with an 8.6-mm upper endoscope and through-the-scope balloons (size: 11-18 mm). Pre- and posttreatment Pouchitis Disease Activity Index symptom scores (range: 0-6), endoscopic stricture scores based on resistance in passing the endoscope (range: 0-4), and Cleveland Global Quality of Life were compared. RESULTS: Nineteen patients with pouch strictures who had concurrent Crohn's disease of the pouch (n = 11), cuffitis (n = 5), and pouchitis (n = 3), including 14 inlet and 14 outlet strictures, were enrolled. The mean number of strictures for each patient was 1.61 +/- 0.78. All strictures were successfully dilated with the through-the-scope balloon, with a mean of 1.74 +/- 1.19 (range: 1-5) sessions for each patient. Nine patients had a second endoscopy at 8 wk and five patients had a third pouch endoscopy at 16 wk after the initial endoscopic dilation. Endoscopic stricture scores immediately (0.30 +/- 0.47), 8 wk (0.40 +/- 0.51), and 16 wk (0.44 +/- 0.76) after the dilation were significantly improved compared to the predilation stricture scores (2.67 +/- 0.78). The symptom scores and quality-of-life (QOL) scores improved at week 8 and 16 following dilation, with a mean follow-up of 6.10 +/- 5.83 months (2-25 months). No complications were experienced with the procedure. One patient with CD who failed endoscopic and medical therapy underwent pouch resection. CONCLUSION: In conjunction with medical therapy, outpatient endoscopic balloon dilation appears safe and effective in treating pouch inlet and outlet strictures, by relieving symptoms, restoring pouch patency, and improving QOL in the majority of patients.

Pouch-sacral fistula three years after restorative proctocolectomy for ulcerative colitis.

Fistula formation after restorative proctocolectomy poses a challenge to the surgeon and sometimes can lead to the excision of the pouch. A 21-year-old female patient developed an ileal J-pouch-sacral fistula with abscess and osteomyelitis of the sacrum, more than three years after the pouch construction for ulcerative colitis. Two months prior to this event, the patient had a single and transient episode of pouchitis. The role of pouchitis in the aetiopathogenesis of the fistula is unclear. To our knowledge, the late development of such a fistula has not been reported previously.

Immunodulation with tacrolimus (FK506): results of a prospective, open-label, non-controlled trial in patients with inflammatory bowel disease.

UNLABELLED: Tacrolimus (FK506) is widely used in the organ transplant setting, but not in the treatment of IBD. OBJECTIVE: the aim of this study was to analyse the effectiveness of tacrolimus in specific clinical presentations of inflammatory bowel disease (IBD) in which recurrence is likely. PATIENTS AND METHODS: inclusion criteria were: perianal Crohn's disease (PCD), CD in rectal stump, pouchitis and cuffitis with severely impaired function of the ileoanal pouch (IPAA), and proven refractoriness to other therapies. Clinical assessment: Hughes' classification (PCD); Oresland index (OI) in IPAA, endoscopy-biopsy and Quality of life (QoL) using the Spanish version of the IBDQ. Response was determined as complete (CP), partial (PR) or non-existent (NR). Tacrolimus was administered orally at a dose of 0.1 mg/kg/day (levels 5-15 .g/L). RESULTS: nineteen patients entered the study. Mean duration of treatment was 9.6 +/- 6.3 months. In PCD, CR was reported in 66% of cases and PR in 33%, with disappearance of inflammation, stenosis and ulcers. In patients with pouchitis and cuffitis,77% presented either CR or PR. The OI scores and QoL improved significantly after treatment (p<0.006 and p<0.002, respectively). Adverse effects were minor and controlled by regulating the dose. CONCLUSION: oral administration of tacrolimus is easy to per-form and has few adverse effects when used to treat IBD in certain clinical presentations with a high likelihood of recurrence.

[Probiotics in chronic inflammatory bowel disease].

Current data show that probiotics are more effective in preventing the recrudescence of an inflammatory process than in suppressing active disease. This is reflected in the solid evidence for the effect of E. coli Nissle 1917 (Mutaflor) in the maintenance of remission of ulcerative colitis, and of VSL#3 in preventing the recurrence of pouchitis. These indications have since been incorporated in valid guidelines. Initial clinical studies have also provided promising results regarding the efficacy of VSL#3 in preventing pouchitis immediately following proctocolectomy.

Restorative proctocolectomy: histological assessment and cytometric DNA analysis of ileal pouch biopsies.

BACKGROUND/AIMS: The pathological changes and the risk of developing cancer in the ileal pouch mucosa of patients who received restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) were studied. The presence or absence of remaining rectal mucosa below the IPAA in both patients with stapled and handsewn IPAA was also examined. MATERIALS AND METHODS: Endoscopy of the ileal pouch was performed on 38 patients at 4, 12, 18 and 36 months after restorative proctocolectomy with ileal pouch. Mucosal biopsy specimens were taken from the ileal reservoir in order to assess the histological incidence of inflammation. In 23 patients, biopsies were taken to perform cytometric DNA analysis. Clinical symptoms of pouchitis (over six evacuations in 24 hours, night-time evacuations, leakage of feces, bloody diarrhea, abdominal pain and fever) were recorded and correlated with the histological findings. Biopsies were also sampled below the ileo-anal anastomosis (IPAA) in order to identify residual rectal mucosa. RESULTS: Results of histological assessment showed various degrees of chronic inflammation increasing over time (from 42 to 60%) while the presence of both acute and chronic inflammation of the reservoir was less frequent (from 18 to 30%). Villous atrophy was present in 39-68% of patients and the grade of villous atrophy was correlated to the grade of inflammation. Clinical pouchitis was present in 3 to 8% of cases at the different controls and it was always associated with the highest grade of histological inflammation and severe villous atrophy. No significant alteration of the DNA cellular content was observed. Very low incidence of aneuploidy (0.7-1% Ex.R.) has been reported in three cases. However, we found dysplasia in only one patient who underwent surgical treatment for familial polyposis coli. IPAA evaluation showed no residual rectal mucosa in 40% of cases with stapled IPAA; in the remaining 60%, we found a small amount of rectal mucosa (maximum 1 cm). We did not find rectal mucosa after handsewn IPAA with mucosectomy. CONCLUSIONS: Patients treated with restorative proctocolectomy with IPAA showed a higher and increased incidence of inflammation during follow-up. No significant alteration of DNA cellular content nor dysplasia of the pouch mucosa were observed. In this study the chance of leaving rectal mucosa after stapled IPAA was about 60%.

Ileoanal reservoir dysfunction: a problem-solving approach.

BACKGROUND: Many technical difficulties of the ileoanal reservoir operation have been overcome, allowing acceptable morbidity in the hands of both the frequent and less frequent operator. However, a minority of patients have persistently unsatisfactory pouch function, which can be a difficult problem to manage. METHODS: A Medline search was carried out to identify relevant papers published from November 1996 to January 1978. For clinical information more emphasis was given to recent publications with larger numbers. Where appropriate, information from other sources and some local data were included. RESULTS: Most patients empty the pouch four to eight times a day with perfect continence and no urgency, and are considered to have acceptable function with which they are satisfied. Patients who have poor function beyond an easily treated episode of pouchitis require the expertise of a multidisciplinary team offering some understanding of the anatomy, physiology and pathology of the gastrointestinal tract in general and of the ileal reservoir in particular. A thorough and persistent approach to difficult cases is often rewarded with a good outcome, with the exception of problems arising from postoperative sepsis. The temptation to use pouchitis as a waste-basket diagnosis for poorly understood dysfunction should be avoided. Problems causing poor function may originate in the pouch (including pelvic sepsis), the pouch outlet, or the small bowel above the pouch, and these areas need to be considered in each case. CONCLUSION: To optimize the benefits of restorative pouch surgery, both patients and physicians need to understand aspects of fine tuning of pouch function, including diet, medication and lifestyle. In managing ileoanal reservoir dysfunction the temptation to procrastinate should be resisted; an approach that is systematic and sympathetic should be adopted.

Ileoanal pouch operation: long-term outcome with or without diverting ileostomy.

HYPOTHESIS: Avoiding a diverting ileostomy does not influence the long-term overall morbidity and functional outcome of patients after ileoanal pouch operation (IAP). DESIGN: All patients undergoing IAP were prospectively entered into a database, and those undergoing operation from October 1, 1989, through January 31, 1996, were contacted by mail questionnaire. SETTING: Tertiary referral center. PATIENTS: One hundred thirty unselected sequential patients. INTERVENTIONS: The IAP was completed by a stapled method without diverting ileostomy, provided the patient agreed, and there were no other complicating factors. MAIN OUTCOME MEASURES: Need for reoperation, fecal leakage, pouch frequency, ability to defer evacuation, pouchitis, and overall quality of life. RESULTS: Of 102 patients (78.5%) who initially underwent IAP without diverting ileostomy, 10 (9.8%) developed an anastomotic leak and required a diverting ileostomy. Additional surgery was required in 12 (9.2%) of the 130 patients for bowel obstruction and in 3 (2.3%) for pouch excision. Two patients died of unrelated causes, leaving 125 functioning pouches (96.2%). Questionnaires were completed in 111 (88.8%) of the 125; 75 patients (67.6%) reported perfect continence for gas and stool, 10 patients (9.0%), regular nighttime leakage, and 24 patients (21.6%), occasional fecal leakage. Pouch evacuation frequency (+/-SD) per 24 hours was 7.8+/-2.4 (range, 4-12), and 95.5% of patients could defer pouch evacuation. Of the 111 patients, 42.3% reported pouchitis, with 7.2% receiving long-term antibiotic therapy. Of the patients, 74.8% reported total satisfaction, and 84.7% regarded themselves as being in perfect health. CONCLUSION: Long-term outcome after IAP remains favorable with or without diverting ileostomy.

Significance of reservoir length in the endorectal ileal pullthrough with ileal reservoir.

Ileal reservoirs have been used almost routinely in conjunction with total colectomy and the endorectal ileal pullthrough procedure for ulcerative colitis and familial polyposis. Of 153 patients who underwent surgery at UCLA Medical Center during the past seven years, a comparison was made between 14 patients with an initial reservoir length of greater than 30 cm (large) and 54 patients with a short reservoir (14 to 20 cm). Although patients with long reservoirs had a low stool frequency in the first postoperative year, there was a subsequent increase. During the first two postoperative years, six (43%) of 14 patients developed reservoir enlargement with secondary pouchitis and diarrhea, which severely limited their activities, finally requiring partial resection. Only one of the 14 patients with short reservoirs who underwent surgery more than two years previously had a resection. Complications requiring operative treatment were more than five times greater in patients with long reservoirs. All patients with shortened reservoirs experienced dramatic improvement in their clinical course within one month. Ileal reservoirs of 14 to 16 cm in length appear to provide long-term, excellent clinical function, with an incidence of pouchitis of less than 5%. Symptoms in patients with large reservoirs may be greatly improved by reservoir shortening.

Long-term function and manovolumetric characteristics after ileal pouch-anal anastomosis for ulcerative colitis.

BACKGROUND: Long-term pouch function and physiological characteristics after ileal pouch-anal anastomosis (IPAA) are poorly described. The aim of this study was to undertake a prospective investigation of long-term pouch function and manovolumetric characteristics. METHODS: Forty-two patients with a median follow-up of 16 years after IPAA were included. Function was assessed using a questionnaire and a score was calculated ranging from 0 to 15 (15 being the worst). Manovolumetry was performed and pouchitis recorded. A paired analysis was conducted, as the results were compared with previous data for each patient. RESULTS: The median functional score was 3.5 (range 0-10) at 2 years and 5 (range 1-11) at 16 years (P = 0.013). Resting anal canal pressures were higher (P < 0.001) and squeeze pressures lower (P = 0.008) at long-term follow-up. Ileal pouch volumes at distension pressures of 10, 20 and 40 cm H(2)O were diminished at 16 years (P < 0.001, P = 0.005 and P = 0.058 respectively). The volume and pressure for first sensation and urge to defaecate were reduced. Increased age correlated positively with a poor functional score. A history of pouchitis did not affect functional or physiological characteristics. CONCLUSION: Ileal pouch function declines in the long term. The reasons are unclear, but the ageing process may have an impact.

Laparoscopic management of urolithiasis in a continent urostomy.

BACKGROUND: Urinary calculi formation is an infrequent but challenging late complication of continent urostomy. Percutaneous endoscopic management of two patients with symptomatic pouch urolithiasis is described. CASES: A 48-year-old woman with a history of cervical squamous cell carcinoma (SCC) treated with primary chemoradiotherapy presented with recurrent pain and urinary tract infections (pouchitis). She had undergone continent urostomy 4 years previously for management of a vesicovaginal fistula. A 59-year-old woman following exenteration with continent diversion for recurrent cervix SCC had a 6-month history of refractory pouchitis. In both women, multiple pouch urinary calculi were identified. Their continent reservoirs were, in part, created using titanium staplers. Percutaneous CO(2) endoscopy afforded identification and removal of their stones and staples without complication. CONCLUSION: Successful treatment of continent urostomy urolithiasis is accomplished by percutaneous endoscopy.

Factors affecting anal continence after restorative proctocolectomy.

The aim of this multicentre study was to define the incidence of disordered continence after restorative proctocolectomy and ileoanal reservoir with respect to some factors which may influence the postoperative soiling rate. Two hundred and seven patients underwent the operation, 156 had their ileostomy closed and were all available for a functional assessment. Minor leakage was observed in 26.9% of cases, whereas 1.9% complained of troublesome faecal soiling. None had gross faecal incontinence. Patients over 45 years had significantly more soiling than those younger (45% vs 24%, p less than 0.05). Soiling was more prevalent in those with ulcerative colitis than with other diseases (35% vs 18% p less than 0.05). The soiling rate decreased after the first postoperative year from 34% to 21% (p less than 0.05). A bowel frequency higher than 5 evacuations/24 hours increased soiling from 20% to 48% (p less than 0.01). Pouchitis doubled the soiling rate from 26% to 50% (p less than 0.05) without there being any difference in sphincter function. Soiling was not significantly related to staged procedure, J-pouch, perineal complications or a long rectal cuff. Careful preoperative evaluation of the anal sphincter should be performed in older patients operated on for colitis as they are likely to leak during the first year following restorative proctocolectomy, especially in cases with diarrhoea or pouchitis.

Risk factors for pelvic pouch failure.

PURPOSE: This study was designed to identify factors associated with pelvic pouch failure. METHOD: A retrospective review of patients undergoing the pelvic pouch procedure with a minimum of 30 months follow-up was conducted. RESULTS: A total of 551 patients had pelvic pouch procedures from 1981 to 1992. Forty-nine patients (8.8 percent) have undergone pouch excision, and 9 (1.6 percent) have been defunctioned, for 58 (10.5 percent) patients with pouch failure. Cause of failure was leakage from the ileoanal anastomosis (IAA) in 21 (39 percent) patients, poor functional results in 13 (23 percent), pouchitis in 7 (12 percent), pouch leakage in 7 (12 percent), perianal disease in 7 (12 percent), and miscellaneous in 3 (5.2 percent). Nine of 22 patients (41 percent) had pouch failure during the first two years, with 2 of 147 patients (1 percent) having failure during the last two years of the study. The 58 patients whose pouches failed (Group 1) were compared with the 493 patients whose pouches did not fail (Group 2). Handsewn IAA (P < 0.001), tension on the IAA (P < 0.001), use of a defunctioning ileostomy (P < 0.01), a diagnosis of Crohn's disease (P < 0.001), and a leak from the pouch (P < 0.001) or the IAA (P < 0.001) were associated with pouch failure. Pouchitis was not a risk factor. CONCLUSION: The majority of pouch failures were caused by leaks at the IAA. Although the leak rate remained stable, leaks following a stapled anastomosis seemed to have a better prognosis than leaks following a handsewn anastomosis. Experience with the pouch procedure and the management of complications likely plays an important role in decreasing the risk of pouch failure.

Rectal compliance as a routine measurement: extreme volumes have direct clinical impact and normal volumes exclude rectum as a problem.

PURPOSE: The clinical impact of rectal compliance and sensitivity measurement is not clear. The aim of this study was to measure the rectal compliance in different patient groups compared with controls and to establish the clinical effect of rectal compliance. METHODS: Anorectal function tests were performed in 974 consecutive patients (284 men). Normal values were obtained from 24 controls. Rectal compliance measurement was performed by filling a latex rectal balloon with water at a rate of 60 ml per minute. Volume and intraballoon pressure were measured. Volume and pressure at three sensitivity thresholds were recorded for analysis: first sensation, urge, and maximal toleration. At maximal toleration, the rectal compliance (volume/pressure) was calculated. Proctoscopy, anal manometry, anal mucosal sensitivity, and anal endosonography were also performed as part of our anorectal function tests. RESULTS: No effect of age or gender was observed in either controls or patients. Patients with fecal incontinence had a higher volume at first sensation and a higher pressure at maximal toleration (P = 0.03), the presence of a sphincter defect or low or normal anal pressures made no difference. Patients with constipation had a larger volume at first sensation and urge (P < 0.0001 and P < 0.01). Patients with a rectocele had a larger volume at first sensation (P = 0.004). Patients with rectal prolapse did not differ from controls; after rectopexy, rectal compliance decreased (P < 0.0003). Patients with inflammatory bowel disease had a lower rectal compliance, most pronounced in active proctitis (P = 0.003). Patients with ileoanal pouches also had a lower compliance (P < 0.0001). In the 17 patients where a maximal toleration volume < 60 ml was found, 11 had complaints of fecal incontinence, and 6 had a stoma. In 31 patients a maximal toleration volume between 60 and 100 ml was found; 12 patients had complaints of fecal incontinence, and 6 had a stoma. Proctitis or pouchitis was the main cause for a small compliance. All 29 patients who had a maximal toleration volume > 500 ml had complaints of constipation. No correlation between rectal and anal mucosal sensitivity was found. CONCLUSION: Rectal compliance measurement with a latex balloon is easily feasible. In this series of 974 patients, some patient groups showed an abnormal rectal visceral sensitivity and compliance, but there was an overlap with controls. Rectal compliance measurement gave a good clinical impression about the contribution of the rectum to the anorectal problem. Patients with proctitis and pouchitis had the smallest rectal compliance. A maximal toleration volume < 60 ml always led to fecal incontinence, and stomas should be considered for such patients. A maximal toleration volume > 500 ml was only seen in constipated patients, and therapy should be given to prevent further damage to the pelvic floor. Values close to or within the normal range rule out the rectum as an important factor in the anorectal problem of the patient.

Is ileal pouch-anal anastomosis really the procedure of choice for patients with ulcerative colitis?

PURPOSE: Ileal pouch-anal anastomosis is widely claimed to have replaced total proctocolectomy with ileostomy as the "procedure of choice" for ulcerative colitis, largely on the basis of a perceived improved quality of life. There exists relatively little support for this assertion in the literature. Our aim was to determine if educated patients choosing total proctocolectomy with ileostomy have a similar quality of life as with ileal pouch-anal anastomosis. METHODS: All patients with ulcerative colitis referred to a single surgeon and deemed an appropriate surgical candidate were educated and then offered ileal pouch-anal anastomosis or total proctocolectomy with ileostomy. Age, gender, and complications (including pouchitis) were recorded prospectively, and all patients were questioned regarding functional outcome and level of satisfaction. They were then asked to complete a slightly modified Inflammatory Bowel Disease Questionnaire, which was analyzed by categoric and overall scores. RESULTS: Sixty-seven patients underwent elective surgery for ulcerative colitis during the study period. Fifty-five patients chose ileal pouch-anal anastomosis, and 12 had total proctocolectomy with ileostomy. The groups were similar except for younger age and longer follow-up in the ileal pouch-anal anastomosis group. Patients undergoing ileal pouch-anal anastomosis had significantly more short-term or long-term complications (49 vs. 8 percent), with pouchitis being the most frequent complication. There was no difference in level of satisfaction between the two groups, and no patient in either group wishes they had undergone the other procedure. There was no difference in the overall or any categoric Inflammatory Bowel Disease Questionnaire score. CONCLUSION: Patient satisfaction with both procedures was similarly high. Patients who undergo ileal pouch-anal anastomosis can expect a high level of satisfaction, with a good quality of life. However, educated patients choosing an ileostomy can achieve the same quality of life, without the higher complication rate associated with a pelvic pouch.

The ileal reservoir and ileoanal anastomosis procedure. Factors affecting technical and functional outcome.

A retrospective review was undertaken to determine factors important in predicting functional results following the ileal reservoir and ileoanal anastomosis procedure. One hundred seventy-nine patients underwent ileal reservoir and ileoanal anastomosis at the University of Toronto between December 1981 and January 1987. One hundred sixty-three patients had ulcerative colitis, 11 had familial adenomatous polyposis, and five had Crohn's disease. A J-reservoir was constructed in 72 patients and an S-reservoir in 107 patients. Functional results were assessed in 102 patients who had their loop ileostomies closed for more than one year. The most significant technical complications were anal anastomotic leaks (10 percent), reservoir anastomotic leaks (3.9 percent), anal anastomotic stricture (7.8 percent), late fistula-inano (2.8 percent), small-bowel obstruction (19 percent), and loop ileostomy complications (23 percent). Overweight males and patients with operative blood loss greater than 1000 cc developed anal stricture more frequently (P less than .005). Patients who had a stapled J-reservoir had a higher rate of reservoir leak. The average number of bowel movements reported by patients for 24 hours was 6.2 +/- 3.1. Only ten (9.8 percent) patients had to intubate their reservoir to empty it. Urgency was experienced by 24 patients and soilage at night by 23 (22.5 percent) and during the day by 18 (17.6 percent). Seven patients (6.8 percent) were incontinent during the night and only one during the day. Pouchitis was reported in 16 patients (15.7 percent). Patients with anal anastomotic stricture had more urgency and pouchitis, and had to intubate their reservoir more frequently (P less than .05). No other factors analyzed affected technical or functional results.

Fecal bacteriology and reservoir ileitis in patients operated on for ulcerative colitis.

To investigate the etiology of ileal reservoir inflammation, fecal bacteriology and ileal wall morphology were compared in three groups of 15 patients operated on for ulcerative colitis: 1) conventional ileostomy, 2) Kock ileostomy; and 3) pelvic ileal pouch. Total bacterial counts showed overgrowth of fecal bacteria in each group, but the anaerobic bacterial counts were significantly higher (P less than .05) in the two pouch groups than in the conventional ileostomy group. Mucosal morphology did not differ among the three groups showing either normal mucosa or mild chronic inflammatory changes in most patients. In contrast, five of the six patients with clinical pouchitis had acute inflammatory changes in histologic specimens. Fecal bacteriologic findings in these patients did not differ quantitatively or qualitatively from others. It is concluded that proctocolectomy for ulcerative colitis predisposes to ileal bacterial overgrowth, and after pouch operations especially, anaerobic overgrowth may be one factor in the development of pouch inflammation. Acute clinical pouchitis with clear histologic changes was, however, not connected with specific changes in fecal bacteriology.
