Redo pouches: salvaging of failed ileal pouch-anal anastomoses.

From October 1, 1984 to December 31, 1991 at the Clinica Chirurgica II of the University of Bologna, 140 patients submitted to ileal pouch-anal anastomosis for ulcerative colitis (UC) and familial adenomatous polyposis (FAP). Nineteen patients (13.5 percent) developed septic complications. Of these, 11 patients (7.8 percent) had pelvic sepsis. Eight patients required further surgical intervention. Five patients underwent the redo pouch procedure. Another redo pouch was performed in a patient who had previously, in another hospital, had an ileal pouch-anal anastomosis placed and then removed because of ischemic necrosis of the reservoir. No deaths are reported in the reoperated patients. Currently, five of the six patients who underwent the redo pouch procedure have a well-functioning ileoanal anastomosis. The redo pouch procedure should always be attempted prior to the establishment of pelvic fibrosis.

Supralevator pelvic exenteration with colonic J-pouch-anal anastomosis and Mainz pouch operation with anastomosis to the urethra. Report of a case.

This is the first documented case report in which construction of double pouches, a colonic J-pouch and a Mainz pouch with anastomosis to the urethra, was performed in a patient who underwent supralevator pelvic exenteration. We have shown that the operation is feasible; the patient was continent, except for nightly urinary leakage, and was able to defecate and urinate spontaneously without any catheterization. Based on the experience of this case, we believe that this combined operation results in a better quality of life for the patient because of the avoidance of both urinary and fecal stomas. If justified pathologically, this operation may represent an improvement for those patients with extensive cancer of the rectum, which invades the adjacent anterior viscera, or that of the bladder, which invades the posterior viscera.

Development of invasive adenocarcinoma following colectomy with ileoanal anastomosis for familial polyposis coli. Report of a case.

PURPOSE: Proctocolectomy with ileoanal anastomosis has gained increasing acceptance for the prophylactic treatment of patients with familial polyposis coli. Long-term surveillance of the ileal pouch and the pouch-anal anastomosis has not been emphasized despite concern regarding retained rectal mucosa following the procedure. METHODS: A 34-year-old patient with a strong family history of familial polyposis coli was treated at 14 years of age by single-stage proctocolectomy with straight ileoanal anastomosis. Follow-up proctoscopic examinations revealed development of adenomatous changes at the ileoanal anastomosis. RESULTS: This report presents a patient with familial polyposis coli who developed invasive adenocarcinoma at the ileoanal anastomosis 20 years after proctocolectomy with ileoanal anastomosis. CONCLUSIONS: We stress the need for lifelong proctoscopic surveillance in patients with familial polyposis coli treated by proctocolectomy with ileoanal anastomosis.

Factors predictive of persistent or recurrent Crohn's disease in excluded rectal segments.

The fate of the excluded rectal segment after surgery for Crohn's colitis remains poorly defined. To determine prognostic factors relating to the fate of the rectal segment, records of 47 patients who underwent creation of an excluded rectal segment were studied. Disease developed in 33 patients (70 percent) in the excluded rectal segment by five years; 24 patients (51 percent) had completion proctectomy by 2.4 years; and 9 patients (19 percent) retained a rectum with disease at a median follow-up period of five years (range, 2-13 years). At a median follow-up time of six years (range, 2-21 years), 14 patients were without clinical disease. The three groups were equivalent with respect to sex, duration of preoperative disease, indication for operation, distribution of disease, and histologic involvement of the proximal rectal margin. The median age of patients in the proctectomy group at diagnosis tended to be younger than that of patients with a retained excluded rectal segment (22, 30, and 31 years for patients having proctectomy, patients with a diseased excluded rectal segment, and patients with a normal excluded rectal segment, respectively). Neither initial involvement of the terminal ileum nor endoscopic inflammatory changes seen in the rectum predicted eventual disease of the excluded rectal segment. However, initial perianal disease complicating Crohn's colitis was predictive of persistent excluded rectal segment disease and often required proctectomy. Therefore, because the presence of perianal disease and Crohn's colitis predicts persistent or recurrent excluded rectal segment disease, primary total proctocolectomy or early completion proctectomy may be indicated in this subgroup of patients.

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.

Evolutionary changes in the pathologic diagnosis after the ileoanal pouch procedure.

PURPOSE: Inadequate initial differentiation between ulcerative colitis and Crohn's disease may lead to a diagnosis of indeterminate colitis. Construction of an ileoanal pouch in these patients may result in significant morbidity and pouch failure when the ultimate diagnosis is Crohn's disease. METHOD: We prospectively studied 543 patients with idiopathic inflammatory bowel disease to determine whether a patient's pathologic diagnosis changed with time and how it affected outcome. RESULTS: Preoperative diagnosis was ulcerative colitis in 499 patients, indeterminate colitis in 42 patients, and Crohn's disease in 2 patients. Prior colectomy was performed in 58 percent of patients with ulcerative colitis and in all patients with indeterminate colitis and Crohn's disease. Postoperatively, the diagnosis changed in 20 patients with ulcerative colitis (13 to indeterminate colitis, 7 to Crohn's disease). Another two patients with indeterminate colitis showed evidence of Crohn's disease in the resected rectal specimen. As patients were followed up, an additional 13 patients were found to have Crohn's disease (5 indeterminate colitis, 8 ulcerative colitis). With the current diagnosis, perineal complications and pouch failure occurred, respectively, in 23 and in 2 percent of patients with ulcerative colitis, in 44 and in 12 percent of patients with indeterminate colitis, and in 63 and in 37 percent of patients with Crohn's disease. Pathologic diagnosis was altered in 35 patients (6 percent) overall, with a 12-fold increase in the diagnosis of Crohn's disease. Only 3 percent of patients with ulcerative colitis compared with 13 percent of patients with indeterminate colitis had a change in diagnosis to Crohn's disease (P = 0.006; Fisher's exact test). CONCLUSION: Pouch-related complications, eventual pouch failure, and discovery of underlying Crohn's disease occurred in a significant number of patients with a diagnosis of indeterminate colitis. Until more accurate diagnostic differentiation is available, caution is advised in recommending the ileoanal pouch procedure to patients with indeterminate colitis.

Pouchogram: predictor of clinical outcome following ileal pouch-anal anastomosis.

UNLABELLED: Among 914 patients undergoing ileal pouch-anal anastomosis (IPAA) between January 1981 and June 1989, 463 (51 percent) had a pouchogram (meglumine diatrizoate [Gastrografin; E.R. Squibb & Sons, Inc., Princeton, NJ] enema) to assess anastomosis and ileal pouch integrity before closure of the ileostomy. The aim was to determine whether a pouchogram was useful in predicting clinical outcome. RESULTS: Abnormal findings were present in 74 patients (16 percent). These included anastomotic and pouch leaks and anstomotic strictures. Pouchograms were normal in the remaining 389 patients (84 percent). The incidence of significant anastomotic stricturing requiring dilatation under anesthesia was much higher in the abnormal than in the normal pouchogram group (33 percent vs. 4 percent, respectively; P less than 0.001). More significantly, an abnormal pouchogram was associated with an overall long-term failure rate of 23 percent, compared with 6 percent for a normal pouchogram (P less than 0.001). CONCLUSION: Abnormal findings in a pouchogram prior to ileostomy closure indicated those patients at high risk of long-term complications following IPAA.

Predicting the functional result of anastomoses to the anus: the paradox of preoperative anal resting pressure.

UNLABELLED: This article examines the effect of ileal pouch-anal (n = 134) and coloanal (n = 16) anastomoses on resting anal canal pressures in 150 patients. METHODS: Patients underwent anal manometry before ileal pouch-anal anastomosis (IPAA) and coloanal anastomosis (CAA) and again six weeks after ileostomy closure following these procedures. A water-perfused catheter system with four radial ports was used for manometry, pressures being recorded during both station and continuous pull through. RESULTS: Patients with IPAA were younger than those with CAA (34 years vs. 50 years) and had a different ratio of hand-to-stapled anastomosis (1:2.6 vs. 1.3:1). All CAA patients had had rectal cancer while IPAA patients suffered mainly from ulcerative colitis (n = 114) or familial polyposis (n = 10). The mean preoperative resting pressure for all patients was 79 mmHg (75-87, 95 percent confidence limit) and the mean fall in this pressure after surgery was 25 mmHg (-21 to -29, 95 percent confidence limit). There was no difference in preoperative pressure or fall between handsewn and stapled anastomoses, or between IPAA and CAA. CONCLUSION: There was a significant relationship between preoperative pressure and change in pressure that held true for all subgroups (change = -0.7 x preoperative pressure + 31, r = 0.69). Analysis of the functional results confirmed that patients with high preoperative pressure are at risk for severe falls after surgery and are not guaranteed a good result. Conversely, patients with low preoperative pressures may actually have an increase with surgery and are not always incontinent. Patients with low preoperative anal resting pressures should not be denied anastomosis to the anus if they are continent.

Alteration in intestinal permeability after ileal pouch-anal anastomosis.

PURPOSE: The physiologic changes that occur when the small bowel is used as a reservoir, as in the ileal pouch-anal anastomosis, are poorly understood. Alterations in bowel permeability, which may lead to bacterial translocation that could result in illness or dysfunction of the pouch, may be one such consequence of the pouch procedure. METHODS: Whole-bowel permeability was evaluated in patients with and without the pouch through the use of an orally consumed nonmetabolizable sugar clearance technique. Patients in whom the ileal pouch-anal anastomosis was performed for ulcerative colitis (17 patients) and patients with familial polyposis (7 patients) were compared with normal healthy volunteers (10 patients) and patients with ulcerative colitis with and without curative colectomy and ileostomy (6 and 5 patients, respectively). RESULTS: Measured by this technique, no differences were noted in bowel permeability between the volunteers and patients with ulcerative colitis, even after colectomy and ileostomy (1.7 +/- 0.4 in normal healthy volunteers, 1.8 +/- 0.5 in patients with ulcerative colitis without stoma, and 1.4 +/- 0.2 in patients with ulcerative colitis with ileostomy). The group of patients with an ileal reservoir, however, had a significantly increased index of measured bowel permeability (3.5 +/- 0.5 in patients with ulcerative colitis and 5.1 +/- 0.7 in patients with familial polyposis; P < 0.05 by analysis of variance compared with normal healthy volunteers and patients with ulcerative colitis with or without ileostomy). CONCLUSION: The exact site, cause, and consequence of this possible alteration of bowel permeability are unclear but appear to be related to the presence of the pouch and are not caused by the underlying pathologic diagnosis.

Influence of sleep on anal sphincteric pressure in health and after ileal pouch-anal anastomosis.

Fecal incontinence at night may be a disturbing consequence of ileal pouch-anal anastomosis (IPAA). The hypothesis was that decreases in anal canal resting pressure occur as sleep deepens and that the decreases are more profound in pouch patients with incontinence than in controls. Using a sleeve catheter assembly for recording intraluminal and canal pressure and polysomnographic recordings of sleep stages, progressive decreases in anal canal resting pressure with deepening sleep occurred in 11 healthy controls (mean +/- SEM: 57 +/- 3 mm Hg to 43 +/- 3 mm Hg: P less than 0.05) and in 11 patients after IPAA (55 +/- 3 mm Hg to 42 +/- 4 mm Hg; P less than 0.05). Minute-to-minute variations in mean pressure were also found in both controls and IPAA patients, and they were greater at night in patients (P less than 0.05), except during rapid eye movement (REM) sleep. In three patients, resting pressure during REM sleep decreased markedly to 31 +/- 8 mm Hg. This decrease plus the variations in pressure during REM sleep led to incontinence. In conclusion, decreases in anal resting pressure coupled with marked minute-to-minute variations in pressure during sleep occurred in controls and in patients after IPAA and, when profound, led to nocturnal fecal incontinence in some patients.

Influence of myectomy, ileal valve, and ileal reservoir on the ecology of the ileum.

Fecal bacteriology, fecal volatile fatty acids, and ileal mucosal morphology were studied in dogs after ileoanal anastomosis alone, ileoanal anastomosis and myectomy, ileoanal anastomosis and myectomy with ileoileal valve, and ileoanal anastomosis with duplicated (J) ileal reservoir. The ratio of anaerobes to aerobes was significantly less in stool from dogs which had undergone ileoanal anastomosis compared with each of the other three groups (P less than 0.01). The numbers of streptococci and clostridia both were significantly less in stool from dogs with ileoanal anastomosis alone than in any other group. The concentrations of fecal acetic and propionic acids were significantly less in dogs with ileoanal anastomosis alone than in any other group (P less than 0.05), but there were no significant differences in the concentrations of fecal butyric or valeric acids. The severity of mucosal inflammation and degree of villous atrophy were more marked in the ileum of J reservoirs (P less than 0.01), and the percentage of stool retained after defecation was greater (P less than 0.05) in dogs with J reservoirs than in any other group. Therefore, the use of myectomy resulted in significant changes in the ecology of the distal ileum although changes typical of pouchitis were seen only in dogs with J reservoirs.

Cytomegalic colitis after total colectomy in ulcerative colitis: report of a case.

A 58-year-old man with ulcerative colitis underwent total colectomy and ileorectal anastomosis. Steroid suppositories were administered postoperatively, and he had had no exacerbation in the residual rectum for 12 years. He suddenly presented with frequent bloody stools and anal pain. An intensive intravenous regimen of prednisolone was ineffective. Cytomegalic inclusion bodies were identified in biopsy specimens. Administration of ganciclovir reduced the ulcers remarkably. The clinical course suggested that this deterioration was caused by cytomegalovirus infection from the beginning. Cytomegalovirus colitis should be recognized as an exacerbating factor, even in ulcerative colitis patients who have undergone surgery, especially when the residual bowel inflammation is resistant to steroid therapy.

Delayed ileal pouch-anal anastomosis. Complications and functional results.

In patients with chronic ulcerative colitis (CUC), ileal pouch-anal anastomosis (IPAA) can be performed either at the time of colectomy or as a delayed procedure after total abdominal colectomy and ileostomy. There has been debate as to whether delayed IPAA results in superior functional results, since patients are frequently steroid-free and have little evidence of active disease. To assess this, we analyzed 95 patients who had undergone total abdominal colectomy, either with ileostomy and Hartmann's procedure or with ileorectostomy, 2-183 months prior to IPAA. Postoperative complications and functional results were compared with those of 776 CUC patients who underwent IPAA at the time of abdominal colectomy. Indications for prior colectomy included toxic megacolon (40 percent), failed medical therapy (36 percent), other reasons (e.g., iatrogenic perforation, cancer) (6 percent), and reasons unclear (18 percent). Nineteen percent of delayed-IPAA patients were taking steroids at the time of pouch construction. Follow-ups were similar in the two groups. The incidence of septic and obstructive complications after delayed IPAA vs. IPAA at the time of colectomy were 10.5 percent vs. 5.4 percent and 6.5 percent vs. 14.5 percent, respectively. There were no significant differences in postoperative functional results between the two groups. Delayed IPAA confers no advantage over IPAA performed at the time of colectomy in terms of functional outcome. Delayed IPAA was associated with a significantly higher rate of septic complications but a lower incidence of postoperative obstruction.

Carcinoma and the ileal pouch-anal anastomosis.

Of 362 patients undergoing ileal pouch-anal anastomosis, 12 (five with chronic ulcerative colitis and seven with familial adenomatous polyposis) had 16 associated carcinomas. Incidental carcinoma was found in four patients who had undergone ileal pouch-anal anastomosis, six patients had known carcinoma, and carcinoma was suspected in two patients with high-grade dysplasia. No tumor was Stage C or D. After a median observation period of 24 months, no evidence of recurrence was documented. Data suggest that patients with carcinoma complicating chronic ulcerative colitis and familial adenomatous polyposis can safely undergo ileal pouch-anal anastomosis; however, it may be prudent to perform resection and later ileal pouch-anal anastomosis after a period of observation and appropriate adjuvant therapy because of the difficulty in intraoperative staging.

Colectomy with ileorectal anastomosis lowers rectal mucosal cell proliferation in familial adenomatous polyposis.

Rectal polyp regression has been observed in familial adenomatous polyposis (FAP) after colectomy and ileorectal anastomosis (IRA). In view of the association between risk of neoplasia and epithelial cell turnover rates, a study was conducted to determine the effect of colectomy and IRA on rectal mucosal proliferation in FAP. Endoscopic biopsies of flat rectal mucosa were taken from 12 FAP patients with an established IRA and 10 FAP patients prior to colectomy. Mucosal proliferation was assessed by flash-labeling S-phase cells with bromodeoxyuridine. Labeled cells were visualized on paraffin sections with an immunohistochemical stain using a monoclonal antibody to bromodeoxyuridine. Twenty crypt columns were analyzed. The mean labeling index (percent labeled cells/crypt) of the FAP patients with established IRAs (7.0 +/- 1.4 percent) was significantly less than that of the precolectomy patients (12.8 +/- 3.0 percent) (Mann-Whitney U test, P = 0.0004). Comparison of labeled distribution curves shows a contraction of the crypt proliferative zone in the IRA group. Colectomy with IRA in FAP is associated with a significant reduction in rectal mucosal cell proliferation. These findings support the claim of reduced risk of rectal cancer following this procedure in FAP and are of relevance to the study of environmental vs. genetic control of cell proliferation.

Lymphoma of the pouch after ileal pouch-anal anastomosis: report of a case.

The most common cause of pouch dysfunction after ileal pouch-anal anastomosis is pouchitis. Although low-grade dysplasia in the mucosa of the pouch has been recently described in the presence of pouchitis, there has been no report of carcinoma arising in the pouch itself. We describe a patient who developed a large-cell lymphoma of the ileal pouch after ileal pouch-anal anastomosis.
