Treatment of outflow tract problems associated with continent ileostomy (Kock pouch). Report of six cases.

The Kock pouch procedure has undergone a number of revisions since its conception, including creation of a valve and fascial stabilization. Nevertheless, complications which defeat the goal of continence are not unheard of. Naturally, when such complications arise, the patients are disadvantaged. Major examples include pouchitis and valve leakage. Lesser complications of strictures of the outflow tract, valve prolapse, and tissue loss in the outflow tract are also identified and are surgically remediable. Problems may be successfully addressed by minor corrections under local anesthesia or may mandate more extensive procedures. Examples are provided of such successful cases, which allow patients to derive the benefits of continent ileostomy.

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.

Assessment of peripouch inflammation after ileoanal anastomosis using endoluminal ultrasonography.

PURPOSE: This study was designed to assess the impact of endoluminal transpouch ultrasonography in the investigation and management of inflammatory complications of pelvic pouches and to compare endoluminal transpouch ultrasonography to pouchography and computerized axial tomograph scanning. METHODS: A prospective evaluation was made of the presentation, investigation, treatment, and clinical outcome of 16 patients referred for endoluminal transpouch ultrasonography with dysfunctional pelvic pouches and no evidence of pouchitis on endoscopy. RESULTS: There were 5 normal and 11 abnormal examinations. Six patients had peripouch inflammatory phlegmons, four patients had peripouch abscesses, and one patient had a rectovaginal fistula. A total of nine patients had anastomotic leaks detected. Two patients had abscesses drained under ultrasound guidance and a pigtail catheter left in situ. Pouchography detected only 3 of 8 (38 percent) anastomotic leaks detected by endoluminal transpouch ultrasonography. Computerized axial tomograph scan detected 2 of 5 (40 percent) peripouch abscesses or phlegmon detected by endoluminal transpouch ultrasonography. Patients with peripouch sepsis had significantly thicker anal wall thickness (23.8 vs. 16.8 mm; P < 0.02) and external sphincter thickness (9.1 vs. 7.3 mm; P < 0.05) than pouches with no sepsis. CONCLUSIONS: Endoluminal transpouch ultrasonography appears to detect anastomotic leaks and peripouch sepsis and may guide the initial management of patients with dysfunctional pelvic pouches and an inconclusive clinical and endoscopic examination.

Risk of residual rectal mucosa after proctocolectomy and ileal pouch-anal reconstruction with the double-stapling technique. Postoperative endoscopic follow-up study.

PURPOSE: This study was designed to assess the risk of retained rectal mucosa after proctocolectomy and ileal pouch-anal anastomosis with the double-stapling technique. METHODS: A total of 113 patients underwent proctocolectomy with an ileal pouch-anal reconstruction. In 57 patients the anastomosis between pouch and proximal anal canal was performed using the double-stapling technique. In 26 patients the procedure was carried out without a protecting ileostomy. Of the remaining 31 patients with a proximal ileostomy, 15 underwent endoscopy six weeks postoperatively. Circular biopsies were taken just distal from the pouch-anal anastomosis. RESULTS: Histologic examination revealed rectal mucosa in at least one biopsy in 7 of 15 patients. At follow-up (mean 18 months) no (distal) pouchitis was clinically noticed. In one patient with familial polyposis, a few polyps, distal of the anastomosis, had to be endoscopically removed. CONCLUSIONS: Double-stapled ileal pouch-anal anastomosis has a considerable risk of residual rectal mucosa, because of combined linear transection and circular stapling with bilateral dog-ear formation of rectal mucosa. Residual rectal mucosa did not seem to influence clinical results at follow-up.

Familial adenomatous polyposis: results following ileal pouch-anal anastomosis and ileorectostomy.

To compare the clinical and functional results of ileorectostomy (IR) and ileal pouch-anal anastomosis (IPAA) in patients with familial adenomatous polyposis (FAP), we reviewed the results of 94 IPAA patients and 21 IR patients who were operated upon between 1978 and 1988. The groups were similar with respect to age and sex. None of the patients died postoperatively. Postoperative complications occurred in 28 percent of the IPAA group and in 17 percent of the IR group (P greater than 0.1). Seven percent of IPAA patients described symptoms compatible with pouchitis. Sixty-one percent of IR patients required subsequent fulguration of rectal polyps at least once. IR patients had a mean (+/- SD) of 4 (+/- 2) stools per day, while IPAA patients had 5 (+/- 2) stools per day (P greater than 0.05). No significant difference in daytime soiling was present between IR (6 percent) and IPAA (4 percent). Nighttime spotting was also similar between the two groups. Nighttime soiling, however, was reported by 4 percent of IPAA patients but not by IR patients (P less than 0.05). One IPAA patient (1 percent) required pouch excision for a desmoid tumor, while two IR patients (11 percent) required proctectomy and ileostomy for recurrent dysplastic polyps (P less than 0.05). Adhesions and a shortened ileal mesentery prevented the construction of an ileoanal procedure in these latter patients. In conclusion, the postoperative complication rate and functional results are similar after IR and IPAA in patients with FAP; however, IR does not eradicate rectal polyps and may indeed preclude IPAA for those requiring subsequent proctectomy.

Indeterminate colitis. Long-term outcome in patients after ileal pouch-anal anastomosis.

UNLABELLED: Uncertainty persists concerning the long-term results of ileal pouch-anal anastomosis performed for indeterminate colitis. PURPOSE: This study was designed to compare functional outcomes of ileal pouch-anal anastomosis in patients with typical chronic ulcerative colitis and indeterminate colitis. METHOD: Seventy-one ileoanal pouch patients were identified with a diagnosis of indeterminate colitis. Mean follow-up was 56 months. Outcomes were compared with 1,232 chronic ulcerative colitis patients after ileal pouch-anal anastomosis. Mean follow-up was 60 months. RESULTS: (mean +/- SD) There was no difference in the frequency of daily bowel movements (indeterminate colitis, 7 +/- 3, vs. chronic ulcerative colitis, 7 +/- 2). Daytime and nighttime incontinence rates were likewise similar. Prevalence of pouchitis was identical (33 percent). However, failure rate was higher in the indeterminate colitis group (indeterminate colitis, 19 percent, vs. chronic ulcerative colitis, 8 percent; (P = 0.03)). CONCLUSIONS: At a mean of nearly five years after surgery, failure appears to occur more frequently in patients with indeterminate colitis than in patients with chronic ulcerative colitis. However, the great majority of indeterminate colitis patients (> 80 percent) have long-term functional results identical to those of patients with chronic ulcerative colitis.

Harry E. Bacon Oration. Comparison of the functional results of restorative proctocolectomy for ulcerative colitis between the J and W configuration ileal pouches with sutured ileoanal anastomosis.

PURPOSE: This study was designed to compare function of patients who had undergone reconstruction following proctocolectomy for ulcerative colitis using the J or W configuration ileoanal pouch. METHODS: Of 126 patients who underwent restorative proctocolectomy between January 1981 and March 1993, 101 had surgery for ulcerative colitis. Eighty-seven of these patients were available for review by personal or postal interview. All operative procedures were performed by one surgeon. The group comprised 35 W-pouches and 52 J-pouches. RESULTS: More patients with a J-pouch had a stool frequency of greater than 8 per 24 hours (P = 0.044), and they were also more likely to use a perineal pad (P = 0.019). No difference in the rates of nocturnal stool frequency, fecal incontinence, or use of constipating agents between the two pouch designs was found. Significantly more patients with a J-pouch have had episodes of pouchitis (P = 0.001). Of the total patient group 91.9 percent felt that restorative proctocolectomy had improved their quality of life. CONCLUSION: Minor differences in the function of the W configuration ileoanal pouch and the J configuration ileoanal pouch are demonstrated in this study.

Pull-through procedures performed months to years after permanent proctectomy.

PURPOSE: Patients who have undergone proctectomy without concomitant rectal reconstruction or coloanal anastomosis were not normally considered candidates for re-establishment of anal continuity until a case report published in 1985. With the addition of nine patients, reported herein is a series of ten patients who have undergone delayed pull-through procedures months to years after permanent proctectomy. PATIENTS: Ten patients (including the single case reported in 1985) have undergone delayed pull-through procedures up to 24 years after permanent proctectomy and ostomy formation. Delayed ileal pouch-anal anastomoses were performed in nine patients, and delayed coloanal anastomosis was performed in one patient. There were four males and six females, each of whom had evidence of external sphincter contraction on physical examination. Average age was 33 (range, 24-51) years at the time of reconstruction. Average duration of follow-up is 32 (range, 1-96) months. RESULTS: One patient is awaiting ileostomy closure. Five of nine patients use constipating agents. Two patients are constipated and use enemas to aid in evacuation. None are wearing protective undergarments. One patient had his ileostomy reconstructed eight years after delayed pull-through for uncontrollable diarrhea associated with chemotherapy for multiple myeloma and recently died. Postoperative complications included wound infection (3), enterocutaneous anastomotic stricture requiring anoplasty (2), small bowel obstruction (1), pneumonia (1), presacral abscess (1), and pouchitis (1). CONCLUSIONS: Delayed pull-through procedures performed months to years after permanent proctectomy can be performed in selected patients, with results comparable to rectal reconstruction done at the time of proctectomy.

Double-stapled vs. handsewn ileal pouch-anal anastomosis in patients with chronic ulcerative colitis.

UNLABELLED: Proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the treatment of choice for most patients with chronic ulcerative colitis. Whether or not a double-stapled technique, which should preserve the anal transition zone and avoid prolonged and dilation, facilitates superior fecal continence compared with conventional mucosal resection and handsewn anastomosis is unknown. PURPOSE: The aim of this study was to compare functional results after double-stapled and handsewn IPAA. METHODS: Twenty-seven consecutive patients (13 females, 14 males; mean age, 37 years) who had proctocolectomy and double-stapled IPAA (J) for chronic ulcerative colitis were identified. Each was matched by sex, age, and surgeon to a control who had undergone a conventional handsewn anastomosis. Functional results at six months after ileostomy closure were compared. RESULTS: Median stool frequency in each group was seven. The prevalence of pouchitis was 22 percent in both groups. One pouch failure occurred in each group. The percentage of patients from the double-stapled group with daytime spotting was similar to that of the handsewn group (18 percent vs. 26 percent, P > 0.5). Nighttime soiling rates were similar as well (41 percent vs. 48 percent, P > 0.5). CONCLUSIONS: Double-stapled IPAA appears to convey no early functional advantage over handsewn IPAA for chronic ulcerative colitis.

Crohn's disease-associated genetic marker is seen in medically unresponsive ulcerative colitis patients and may be associated with pouch-specific complications.

PURPOSE: Genetic markers have been used to define subgroups of patients within the broad categories of Crohn's disease and ulcerative colitis that may differ in clinical course and response to medical therapy. The tumor necrosis factor microsatellite haplotype a2blc2d4e1 has been found previously to be present in 24 percent of patients with Crohn's disease and only 5 percent of patients with ulcerative colitis. This study examined associations between this microsatellite haplotype and the postoperative clinical course of patients with ulcerative colitis undergoing ileal pouch-anal anastomosis. METHODS: As part of a large, controlled, prospective study to correlate genetic markers with clinical phenotypes, tumor necrosis factor microsatellite alleles at five loci (a, b, c, d, and e) were determined from genomic DNA by polymerase chain reaction in 32 patients with a clinical and histopathologic diagnosis of ulcerative colitis who underwent ileal pouch-anal anastomosis for medically unresponsive disease. All patients with ileal pouch-anal anastomosis were also studied prospectively for pouch-specific complications. RESULTS: The tumor necrosis factor haplotype a2blc2d4e1 was present in 11 patients. Median follow-up was 19 months. Thirteen patients had a pouch-specific complication (12 pouchitis and 1 pouch-perineal fistula). Six of 11 patients (55 percent) with the haplotype had a pouch-specific complication compared with 7 of the 21 patients (33 percent) who did not possess this haplotype (P = 0.22). Median time from surgery to pouch-specific complication was eight months. Patients with the haplotype had a median time to pouch-specific complication of three months, whereas patients without the haplotype had a median time of 11 months (P = 0.04). In addition, 36 percent of patients with the haplotype had chronic pouch complications vs. only 10 percent of patients without the haplotype (P = 0.05). CONCLUSION: The Crohn's disease-associated tumor necrosis factor haplotype a2blc2d4e1 may define a subgroup of medically unresponsive patients with ulcerative colitis who are predisposed to a higher incidence of pouch-specific complications after ileal pouch-anal anastomosis.

Physiologic evaluation and surgical management of failed ileoanal pouch.

BACKGROUND: Following proctocolectomy and ileal pouch-anal anastomosis, a small percentage of patients will have poor functional results attributable to pouchitis or anastomotic or septic complications. Additionally, functional failures can occur secondary to limited pouch capacity and compliance. We present five such patients managed with operative conversion to W-ileal pouch-anal anastomosis and examined physiologic parameters important for improving functional results. METHODS: Five female patients (mean age, 30 (range, 24-39) years) with poorly functioning J-ileal pouch-anal anastomoses were referred for evaluation with symptoms of high stool frequency and incontinence problems. Three had severe nocturnal incontinence, and the remaining two patients experienced minor nocturnal incontinence. Preoperative and postoperative evaluation included barium pouch studies, flexible sigmoidoscopy, anal manometry, evacuation volume, and pouch compliance. Pouch-to-anal pressure gradients were calculated. To improve reservoir capacity and compliance, all five patients underwent conversion to W-ileal pouch-anal anastomoses. RESULTS: Twenty-four hour and nocturnal stool frequencies decreased from 13.8+/-1.7 and 3+/-1.3 to 5.8+/-0.3 and 0.3+/-0.2 postconversion (P < 0.05). Mean pouch evacuation volume increased from 83+/-27 to 290+/-29 ml postoperatively (P < 0.05). Pouch compliance increased from 2.7+/-0.5 mmHg/ml to 7.7+/-0.6 mmHg/ml postconversion (P < 0.05). Improvement in postconversion stool frequency correlated with an increase in pouch evacuation volume (r=-0.87). All patients reported improved day and nocturnal continence, despite no significant change between preoperative and postoperative anal manometric pressures. Improved continence correlated with a significant widening of the pouch-to-anal pressure gradients, which increased from 5 to 25 mmHg at 150 ml following pouch conversion. CONCLUSIONS: Poorly functioning ileal reservoirs secondary to limited capacity and compliance can be successfully managed with conversion to W-ileal pouch-anal anastomosis. The increased pouch capacity is associated with improvement in compliance and widening of the pouch-to-anal pressure gradients, providing excellent functional results.

Mesenteric lengthening in ileoanal pouch anastomosis for ulcerative colitis: Is high division of the superior mesenteric pedicle a safe procedure?

PURPOSE: Lengthening of the mesentery is the technical key point of the ileoanal pouch procedure. Division of the superior mesenteric pedicle high in the mesentery is an original artifice that regularly provides sufficient descent of the pouch to reach the dentate line without any tension. A retrospective study compares two groups of patients with ulcerative colitis. METHODS: Group 1 consisted of 21 patients with superior mesenteric pedicle division (mean lengthening, 6.1 cm), and Group 2 consisted of 44 patients without superior mesenteric pedicle division. Mortality and postoperative and late morbidity were studied along with functional outcome. RESULTS: One patient died in Group 2 (postoperative pelvic sepsis); one patient died in Group 1 at six months from late liver transplant complications. Postoperative morbidity was insignificantly less important in Group 1 (P=0.02). Five patients in Group 2 had the pouch removed; none in Group 1 did. Pouchitis episodes developed in both groups, with no significant difference (P=0.5). Three patients in Group 1 developed anastomotic stenosis vs. 8 in Group 2 (P=0.5). Functional results at one-month, one-year, and two-year follow-ups are not significantly different, except that nighttime stool frequency increased in Group 2. CONCLUSIONS: On the whole, morbidity and functional outcome appear similar. This suggests that high superior mesenteric pedicle division has no adverse effect and can be proposed routinely as an effective lengthening technique.

Severe steroid-unresponsive ulcerative colitis: outcomes of restorative proctocolectomy in patients undergoing cyclosporin treatment.

PURPOSE: The recent introduction of the immune suppressor cyclosporin for treatment of steroid-refractory ulcerative colitis has required surgeons to perform a colectomy in those patients who eventually fail this rescue treatment, thus raising questions as to the safety of surgery as performed in patients with a heavily manipulated immune system. To assess the rates of mortality and morbidity in this setting, we studied a cohort of consecutive patients who had surgery after failing cyclosporin for refractory ulcerative colitis at our center. METHODS: Between January 1991 and December 1996, 25 patients with ulcerative colitis underwent restorative proctocolectomy performed in three steps (21 patients) and in two steps (4 patients). Seventeen of the 25 patients (68 percent) were initial nonresponders to a dose of 2 mg/kg/day of intravenous cyclosporin and underwent surgery immediately, the remaining 8 (32 percent) relapsed as outpatients on oral cyclosporin and were readmitted for surgery. RESULTS: There was no operative mortality. Nine patients of the 25 developed postoperative (early) complications (36 percent). The three-step operation subset had a 28 percent complication rate, the two-step 75 percent. Three patients needed reoperation. A total of 11 patients (44 percent) reported with late complications: two patients required surgical treatment, one for obstruction and one for pouch-perianal fistula. Three cases of pouchitis were recorded. No patient required pouch removal. CONCLUSION: Given the absence of postoperative mortality and a low overall complication rate, restorative proctocolectomy can safely be performed in patients who fail rescue treatment with a dose of 2 mg/kg of cyclosporin for steroid-refractory ulcerative colitis. Corollary evidence in this article hints but does not prove that the three-step procedure is safer than the two-step operation.

Long-term functional evaluation of straight coloanal anastomosis and colonic J-pouch: is the functional superiority of colonic J-pouch sustained?

AIM: This study was designed to analyze the functional and clinical outcomes of straight coloanal anastomosis compared with colonic J-pouch performed after low anterior resection. MATERIALS AND METHODS: Between September 1989 and June 1996, all patients who underwent low anterior resection with anastomosis less than 4 cm from the dentate line were classified into two groups based on the restoration of intestinal continuity: "straight" coloanal anastomosis (n = 39) or colonic J-pouch (n = 44). Both groups were assessed according to the level of anastomosis, anastomotic complications (stricture, leak, pelvic abscess), age, and gender. For comparison of functional outcome, daily bowel movements, tenesmus, urgency, incontinence score (range, 0-20), and anorectal manometric findings were evaluated preoperatively and at six months, and one and two years after surgery. RESULTS: There were no significant differences between the groups relative to age: (coloanal anastomosis, 66.3 +/- 10.1 (range, 46-86), vs. colonic J-pouch, 64.9 +/- 13.2 (range, 39-88) years); gender (females): (coloanal anastomosis, 46.2 percent vs. colonic J-pouch; 38.6 percent); diagnosis: (rectal carcinoma: coloanal anastomosis, 84.6 percent, vs. colonic J-pouch, 77.3 percent); preoperative incontinence score (coloanal anastomosis, 1.5 +/- 4.6, vs. colonic J-pouch, 1.1 +/- 4); bowel movements: (coloanal anastomosis, 2.1 +/- 2.3, vs. colonic J-pouch, 2.1 +/- 1.9/day); level of anastomosis: (coloanal anastomosis, 1.8 +/- 1.3, vs. colonic J-pouch, 1.5 +/- 1.3 cm from the dentate line); history of perioperative radiation therapy: (coloanal anastomosis, 15.4 percent, vs. colonic J-pouch, 20.5 percent); or manometric findings. There was also no significant difference in postoperative mortality: (coloanal anastomosis, 5.1 percent, vs. colonic J-pouch, 2.3 percent); or anastomotic complications: (coloanal anastomosis, 7/39 (17.9 percent), vs. colonic J-pouch, 2/44 (4.5 percent) P = 0.08); strictures: (10.3 vs. 0 percent); leaks: (5.1 vs. 2.3 percent); bleeding: (2.6 vs. 0 percent); rectovaginal fistula: (0 vs. 2.3 percent). Also, in the colonic J-pouch group, two patients developed pouchitis, and one patient experienced difficult evacuation one year after surgery. There was a statistically significant better function judged by less frequent bowel movements (4 +/- 2 vs. 2.4 +/- 1.3/day; P < 0.005) and urgency (36.7 vs. 7.7 percent; P < 0.05), incontinence score (2.2 +/- 3.7 vs. 0.8 +/- 1.6; P < 0.05) up to one year after surgery. At two years, the coloanal anastomosis group did not show statistical improvement in functional results compared with one year postoperatively. Rectal compliance in manometric findings was significantly increased in the coloanal anastomosis group at one year after surgery (12.4 +/- 12.6 vs. 4.2 +/- 1.5 ml/mmHg; P < 0.05). However, these differences were less profound after two years. CONCLUSION: The functional superiority of the colonic J-pouch was greatest at one year after surgery. By two years, adaptation of the "straight" coloanal anastomosis yielded similar functional results. However, the almost fourfold reduction in anastomotic complications in the colonic J-pouch group reveals a second potential advantage of this technique.

Enteral inulin does not affect epithelial gene expression and cell turnover within the ileoanal pouch.

PURPOSE: This study evaluates the effects of enteral inulin on ileoanal pouch functioning by studying epithelial gene expression, cell turnover, and mucosal morphology. METHODS: Twenty patients with an ileoanal pouch received 24 g of inulin daily for three weeks, then a four-week wash-out period, and a placebo for three weeks. In this randomized, double-blind, crossover study, biopsy specimens of pouch mucosa were taken after each test period. Mucosal morphology, inflammation, epithelial proliferation, and cell death were assessed histologically. Expressions of proapoptotic and antiapoptotic regulators, intestinal fatty acid-binding protein, and mucin were quantified by Western blotting or enzyme-linked immunosorbent assay. The number of intestinal fatty acid-binding protein expressing cells was histologically assessed and a high iron diamine/Alcian blue staining was performed to discriminate between sulfated and nonsulfated acidic mucins. RESULTS: Inulin supplementation neither altered mucosal morphology nor influenced inflammation, epithelial cell proliferation, or cell death. The ratio between the proapoptotic and antiapoptotic regulators did not change after inulin supplementation. The number of intestinal fatty acid-binding protein-producing enterocytes and the intestinal fatty acid-binding protein expression level increased after inulin treatment, but did not reach statistical significance. The intestinal fatty acidbinding protein expression level correlated with the Pouchitis Disease Activity Index, which was at the brink of significance (P = 0.06). Mucin expression and the ratio between sulfated and nonsulfated acidic mucins were not altered by inulin supplementation. CONCLUSION: In this prospective study, inulin supplementation did not significantly alter pouch mucosal functioning because neither epithelial homeostasis nor epithelial gene expression was significantly altered by enteral inulin.

Ileal pouch-anal anastomosis in patients with colorectal cancer: long-term functional and oncologic outcomes.

UNLABELLED: When colorectal cancer complicates chronic ulcerative colitis or familial adenomatous polyposis, the role of ileal pouch-anal anastomosis is uncertain because of concerns that the procedure may compromise oncologic therapy and that oncologic therapy may compromise ileal pouch-anal anastomosis function. AIM: This study was undertaken to investigate the impact both of ileal pouch-anal anastomosis on cancer outcomes and of cancer treatments on ileal pouch-anal anastomosis function. PATIENTS AND METHODS: Of 1,616 patients undergoing ileal pouch-anal anastomosis for chronic ulcerative colitis or familial adenomatous polyposis (1981-1994), 77 patients were identified with adenocarcinoma of the colon (56), rectum (17), or both (4). Data were obtained from an ileal pouch-anal anastomosis registry, case notes, and postal and telephone surveys. RESULTS: Mean age of the 77 index patients was 37 (range, 13-60) years. Stage distribution was as follows: Stage 0, 9; Stage I, 31; Stage II, 15; Stage III, 22 patients. Twelve patients died with systemic disease (6 with a local component) after a mean follow-up of 6 (range, 2-15) years. Twenty-two patients received adjuvant therapy (chemotherapy, 16; radiotherapy, 2; both, 4 patients). Chemotherapy complications requiring dose reduction or interruption occurred in three (15 percent) patients. One patient developed radiation enteritis (17 percent). Pouch failure occurred in 16 percent of cancer patients, compared with 7 percent for the overall registry. There were no differences between cancer and non-cancer groups in operative complications, median stool frequency, incontinence, pad usage, or pouchitis. CONCLUSIONS: Although pouch failure is more common, ileal pouch-anal anastomosis can be performed in the setting of colorectal cancer without significant impact on oncologic outcome or long-term ileal pouch-anal anastomosis function.

Status of the endorectal ileal pullthrough procedure for ulcerative colitis and polyposis.

Since 1977, 174 patients with ulcerative colitis and 16 with polyposis underwent colectomy with endorectal ileal pullthrough in two stages with a temporary ileostomy. Five had an S, three a J, and 15 had no reservoir (NR); 97 had a lateral reservoir (LR) constructed at the second, and 70 at the first operation. Ten patients with NR and one with JR were converted to LR because of unacceptable stool frequency. Three patients with SR and seven of 178 LR patients (3.9 per cent) returned to a permanent ileostomy or Kock pouch. More than 65 per cent of complications occurred in the first 50 patients. Late reservoir shortening was necessary in 36 patients. Of the last 115 patients, 112 are functioning well with a mean of six bowel movements per 24 hours. The endorectal ileal pullthrough with reservoir provides a good option to the standard proctocolectomy for patients with ulcerative colitis or polyposis. In our experience, a short rectal muscle cuff (less than 5 cm), removal of all rectal mucosa to the dentate line, and construction of a short LR (less than 15 cm) at the first operation produces the fewest complications and the best results. The majority of complications, including pouchitis, can be either avoided or corrected surgically.

Outcome of "indeterminant" colitis following ileal pouch-anal anastomosis.

To establish whether patients with indeterminant colitis (patients with ulcerative colitis whose surgical specimens also show features of Crohn's colitis) have an adverse outcome after ileal pouch-anal anastomosis (IPAA), the authors reviewed the pathologic reports and postoperative status of 514 consecutive patients who underwent IPAA for chronic ulcerative colitis (CUC). Twenty-five patients (5 percent) had features of indeterminant colitis (IC), including unusual distribution of inflammation, deep linear ulcers, neural proliferation, transmural inflammation, fissures, creeping fat, and retention of goblet-cell population. The clinical and functional outcome of these 25 IC patients was compared with that of the remaining 489 CUC patients. The mean follow-up was 38 +/- 18 months. No significant differences in complication rates, pouch function, incidence of "pouchitis," or requirement for pouch excision were detected in the two groups at follow-up. Although the authors are continuing to perform IPAA on patients with IC, a better definition of the IC patient and a more objective, prospective analysis of outcome of IC following IPAA is required before confident and specific treatment policies can be recommended.
