Pouchitis--a poorly understood entity.

Pouchitis is an increasing drawback to patients who undergo ileal pouch-anal anastomosis for ulcerative colitis; complication overshadows the overall good functional results of this sphincter-saving operation. There is a need for cooperative, multicenter, and longitudinal studies of patients undergoing ileal pouch-anal anastomosis, to unravel the etiology and pathophysiology of pouchitis. Because of the absence of a mucosal inflammation before pouch construction, patients operated on for familial adenomatous polyposis are the perfect control group. Thus, it may be possible to elucidate and define the sequence that leads to pouchitis, including overgrowth of a colonic type flora, transformation of the histology to an epithelium with colonic features, an altered biochemical milieu in the lumen (volatile fatty acids, secondary bile acids), and changes in mucosal defense mechanisms.

Previous subtotal colectomy with ileostomy and sigmoidostomy improves the morbidity and early functional results after ileal pouch-anal anastomosis in ulcerative colitis.

The aim of this work was to study the effects of previous subtotal colectomy (STC) with ileostomy and sigmoidostomy on the outcome of ileal J-pouch-anal anastomosis (IPAA) in patients with acute ulcerative colitis. Between 1983 and 1991, we conducted a prospective, nonrandomized study of 156 patients who underwent IPAA in our center. Fifty-five patients (34.3 percent) had undergone STC with ileostomy and sigmoidostomy for either severe acute colitis (36.5 percent of cases) or nonresolving acute colitis (63.5 percent) up to six months before IPAA with covering ileostomy. There were no perioperative deaths; six patients (11 percent) developed complications requiring reoperation (three cases of pelvic sepsis, two occlusions, and one stenosis of the ileostomy). IPAA was successfully carried out at a later stage in all cases. The results of IPAA in these patients were compared with those in 78 patients who underwent the classical two-stage IPAA procedure. The rates of pelvic sepsis and postoperative occlusion were lower in the subgroup of patients who underwent the three-step procedure. Three months after closure of the ileostomy, the mean number of daily stools was significantly lower in the patients who had undergone prior STC (5.09 vs. 5.9), but there was no significant difference between the two groups with regard to diurnal and nocturnal continence, the need to wear a pad, discrimination between gas and stools, or the use of antidiarrheal medication. In addition, there was no significant difference at one year in terms of functional parameters. We conclude that STC is a simple and safe procedure for the treatment of a severe attack of colitis and that it does not compromise the results of later IPAA. Because it does not increase the morbidity of subsequent IPAA and is associated with more rapid functional recovery, STC appears to be suitable for the treatment of patients with nonresolving acute colitis before the onset of malnutrition or steroid dependency.

Loop ileostomy is a safe option for fecal diversion.

This study was undertaken to prospectively assess all morbidity and mortality associated with temporary loop ileostomy. Eighty-three consecutive patients of a median age of 45 years required temporary fecal diversion after either ileoanal or low colorectal anastomosis (n = 72), for perianal Crohn's disease (n = 5), or for other reasons (n = 6). All loop ileostomies were supported with a rod, and fecal diversion was maintained for a mean of 10 weeks. To date, 67 patients have had re-establishment of intestinal continuity. Stoma closure was affected through a parastomal incision in 64 patients; in three, a laparotomy was required. The closure was stapled side to side in 49 patients, while a hand-sewn anastomosis was done in the other 18 patients; all skin wounds were left open. The mean length of surgery for ileostomy closure was 56 minutes, and the mean hospital stay was five days. Nine patients (10.8 percent) developed 10 complications, nine of which required hospitalization. Specifically, four patients developed dehydration and electrolyte abnormalities secondary to high stoma output, and two had anastomotic leaks that spontaneously healed following conservative management. One patient developed a superficial wound infection that spontaneously drained itself. One patient developed a partial small bowel obstruction that resolved without surgery after a four-day hospitalization. One stoma retracted after supporting rod removal and prompted premature closure. There was no stomal ischemia, hemorrhage, prolapse, or mortality in this series. Thus, loop ileostomy is a safe way to achieve fecal diversion.

The two-chamber ileal pelvic reservoir--an alternative design.

A new ileal pouch design, combining an upper triplicate ileum with a lower duplicate ileum, is described. The physical characteristics of this two-chamber reservoir would lead to better functional results by delaying the filling time of the reservoir.

Long-term results of ileal pouch-anal anastomosis in patients with Crohn's disease.

PURPOSE: Ileal pouch-anal anastomosis (IPAA) is the surgical treatment of choice for most patients with chronic ulcerative colitis. Crohn's disease is, however, a contraindication. Because distinction between UC and Crohn's disease can be difficult, some patients with Crohn's disease inadvertently undergo IPAA. The aim of this study was to determine the long-term outcome of patients with Crohn's disease who have undergone IPAA. METHODS: A total of 37 patients (20 men) were studied. Each had undergone mucosectomy with handsewn IPAA (J-pouch, n = 35; S-pouch, n = 1; W-pouch, n = 1). Histologic examination of the resected specimen at time of IPAA showed features of ulcerative colitiis (n = 22), indeterminate colitis (n = 9), or Crohn's disease (n = 6). The stoma was closed in all patients. RESULTS: A total of 11 of 37 patients developed complex fistulas (pouch-cutaneous (n = 6), pouch-vaginal (n = 4), or pouch-vesical (n = 1). Crohn's disease has recurred in the pouch (n = 20), anal canal (n = 4), pouch and anal canal (n = 10), and elsewhere (n = 3). After ten years (range, 3-14), the pouch remains in situ in 20 patients in whom frequency of bowel movement is seven times (3-10)/24 hours, in situ but defunctioned in seven patients, and excised in ten patients (failure rate, 45 percent). CONCLUSIONS: Inadvertent IPAA for Crohn's disease is associated with a high rate of failure (45 percent) but an acceptable long-term functional result if the pouch can be kept in situ.

Electrophysiologic assessments in pudendal and sacral motor nerves after ileal J-pouch-anal anastomosis for patients with ulcerative colitis and adenomatosis coli.

PURPOSE: To clarify neurologic function with respect to external anal sphincter and puborectalis muscles after J configuration ileal J-pouch-anal anastomosis for patients with ulcerative colitis and adenomatosis coli, we examined the terminal motor latency in the pudendal and sacral motor nerve (S2-4). METHODS: Latency of the response in the external anal sphincter muscle following digitally directed transrectal pudendal nerve stimulation (PNTML) and in the puborectalis muscle following transcutaneous magnetic stimulation of the cauda equina at the levels S2-4 (SMNLTSS) were measured in 12 patients with ileal J-pouch-anal anastomosis; they were divided into a group with continence (7 cases) and a group with soiling (5 cases). Results were compared with data obtained from 12 patients before operation and 15 controls. RESULTS: Conduction delay of PNTML and SMNLTSS in patients with soiling was longest, followed by delay in those without any soiling, then delay in patients before operation, and then controls. In addition, significant differences were also noted between conduction delay of PNTML in controls and those who are incontinent and experience soiling (P < 0.05 and P < 0.01, respectively), and there were significant differences also noted between conduction delay of PNTML in patients before operation and those who are incontinent and experiencing soiling (P < 0.05 and P < 0.01, respectively). Conduction delay of PNTML and SMNLTSS were found in patients before operation rather than in controls. No significant differences were noted between conduction delay of PNTML and SMNLTSS in patients before operation and controls. Significant differences were also noted between conduction delay of PNTML and SMNLTSS in patients who are incontinent and experiencing soiling (P < 0.01, respectively). CONCLUSION: These findings support the hypothesis that soiling after this procedure may be partially caused by damage to pudendal and sacral motor nerves (S2-4).

Surgery for constipation: a review.

PURPOSE: Constipation is related to intestinal motility disorders (colonic inertia (CI)), pelvic floor disturbances (pelvic outlet obstruction), or a combination of both problems. This review summarizes the physiologic and pathophysiologic changes in patients with intractable constipation and gives an overview of surgical treatment options. RESULTS: Although subtotal colectomy with ileorectal anastomosis is the best surgery for CI, there are still approximately 10 percent of patients who will complain of pain and constipation. A completion proctectomy and an ileoanal pouch procedure may be a viable option in a highly select group of patients. In patients with megabowel, reported results are mixed. Subtotal colectomy, partial colectomy for megacolon, and the Duhamel procedure for megarectum have all been reported with variable results. In patients with an isolated distended sigmoid colon, sigmoid colectomy has achieved good results. Anorectal myectomy has not been proven to be successful in the long term. However, in patients with adult short segment Hirschsprung's disease, myectomy can be successful. Patients with pelvic outlet obstruction can be successfully treated with biofeedback. In a small group of patients with a rectocele or a third degree sigmoidocele, surgical intervention yields a high success rate. Division or resection of the puborectalis muscle is not recommended. In patients with a mixed pattern of CI and pelvic outlet obstruction, surgical intervention alone is often not successful. These patients achieve better results by conservative treatment of pelvic outlet obstruction, followed by a colectomy. CONCLUSION: Surgical intervention for patients with intractable constipation is rarely necessary. However, thorough preoperative physiologic testing is mandatory for a successful outcome.

Barnett continent intestinal reservoir. Multicenter experience with an alternative to the Brooke ileostomy.

PURPOSE: Since 1988, surgeons at five hospitals have been performing the Barnett continent intestinal reservoir (BCIR). The BCIR includes modifications to the original Kock pouch, designed to reduce the incidence of valve slippage and fistula formation. Principle modifications include an intestinal collar, an isoperistaltic valve, and a lateral pouch design. METHOD: This unique collaborative study includes 510 ulcerative colitis or familial polyposis patients, with a follow-up time from one to five years postoperatively. RESULTS: Ninety-two percent still have functioning reservoirs. Six and one-half percent have had their pouches removed and replaced with conventional Brooke ileostomies. Reoperation rate for major pouch-related complications (other than pouch removal) was 12.8 percent. These complications included slipped valve (6.3 percent), valve fistulas (4.5 percent), and pouch fistulas (6.3 percent). Several questions were administered to patients whose responses revealed a significant improvement in general quality of life, state of mind, and overall health. CONCLUSIONS: The BCIR represents a successful alternative to patients with a conventional Brooke ileostomy or those who are not candidates for the ileal pouch-anal anastomosis.

Coloanal anastomosis: are functional results better with a pouch?

PURPOSE: Different studies have shown that low colorectal and coloanal anastomosis often yield poor functional results. The aim of the present study was to investigate whether a colonic reservoir is able to improve functional results. METHODS: Thirty-eight consecutive patients subjected to low anterior resection were randomized following rectal excision in two groups. One (n = 19) had a stapled straight coloanal anastomosis, and the other (n = 19) had a 10-cm stapled colonic pouch low rectal anastomosis. Median anastomotic distance above the anal verge was 3.38 +/- 0.56 cm and 2.14 +/- 0.36 cm in both groups, respectively. Continence alterations, urgency, tenesmus, defecatory frequency, anal resting and maximum voluntary squeezing pressures, and maximum tolerable volume were evaluated one year later. RESULTS: One patient died of pulmonary embolism, and seven presented with a recurrence and were excluded from the study. Stool frequency was greater than three movements per day in 33.3 percent of cases with a reservoir and in 73.3 percent of those with a straight coloanal anastomosis (P < 0.05). Maximum tolerable volume was significantly greater in patients with a reservoir (335 +/- 195) than in those without (148 +/- 38) (P < 0.05). There were no significant differences in other variables studied. CONCLUSIONS: This study shows that some aspects of defecatory function after rectal excision could improve with a colonic reservoir.

Endosonography of the anal sphincter after ileal pouch-anal anastomosis. Relation with anal manometry and fecal continence.

PURPOSE: The aim of the present study was to visualize supposed defects of the internal anal sphincter after ileal pouch-anal anastomosis (IPAA) by anal endosonography and to relate these findings with anal manometry and fecal continence. METHODS: We investigated 23 patients, visualized the sphincter complex by anal endosonography, and quantified the anatomic changes of the sphincter. Anal resting and squeezing pressures as well as length of the anal canal were determined by anal manometry. Continence was objectively scored by an observer not involved in treatment of patients and subjectively by patients themselves. RESULTS: At anal endosonography, the mean thickness of the internal anal sphincter was 1.16 mm (95 percent confidence interval, 0.98-1.33), which is significantly less than in normal volunteers. Tapering of the internal anal sphincter only occurred in six patients (of whom two had a gap in the internal sphincter). In 17 patients endosonography showed a thin internal anal sphincter without essential variation in thickness over the complete circumference. Approximately eight weeks after ileostomy closure following IPAA, maximum resting pressure (MRP) and length of the anal canal appeared to be significantly decreased compared with values before IPAA (P = 0.001 and 0.002, respectively). These differences were less striking (P = 0.05 and 0.04, respectively) when measured six or more months after ileostomy closure. The extent of reduction of the MRP and thickness of the internal anal sphincter were not correlated with grade of continence or with subjectively scored continence. CONCLUSIONS: IPAA leads to a reduction of thickness of the internal anal sphincter and reduction of the MRP. Tapering or gaps in the internal anal sphincter are probably caused by direct trauma to this sphincter because of mucosectomy, whereas in cases of circular reduction of thickness of the internal anal sphincter without tapering or gaps, direct trauma is an unlikely explanation; this reduction is probably caused by denervation. IPAA compromises continence to a variable degree in 18 of 23 patients. No correlations were found between the extent of reduction of the MRP and the extent of reduction in internal anal sphincter thickness or between these two parameters and objectively or subjectively scored continence. Difficulties in obtaining reliable information on continence may be a causal factor. A striking discrepancy was noticed among objective, scored disturbances in continence, and overall satisfaction concerning level of continence by patients themselves.

Twenty-year review of the surgical management of perianal Crohn's disease.

PURPOSE: A retrospective analysis of 48 patients treated over a 20-year period (March 1973-April 1993) was undertaken to assess the results of our practice of early surgical intervention in suppurative complications of perianal Crohn's disease. METHODS: All patients were either seen in the office within the last six months or contacted by phone. RESULTS: The average age of our patients was 30 years at initial diagnosis. Thirty-four patients (71 percent) initially presented with intestinal disease and four (8 percent) with only perianal disease. Thirteen patients (27 percent) initially presented with simultaneous intestinal and perianal disease. The various fistulas at initial presentation included 8 intersphincteric (17 percent), 14 transphincteric (29 percent), 11 complex or multiple (23 percent), 5 rectovaginal (10 percent), and 2 unclassified, for a total of 40 patients. Eight patients (17 percent) presented with only an abscess. Eighty five percent of our patients healed after their first procedure, with an average time to heal of 2.8 months. Thirteen (27 percent) patients had recurrences after initial healing of their wounds. The mean time to recurrence after healing was 5.25 years. Fifty-four percent of our recurrences (7 patients) were treated by incision and drainage of an abscess only. Seven of 13 recurrences healed after the second procedure (54 percent), and 5 of 6 healed after a third procedure (83 percent). Only seven (14 percent) of our patients underwent a proctocolectomy during the study period, through September, 1993. Our overall probability of avoiding proctectomy and healing perineal wounds of 86 percent is consistent with published literature. CONCLUSIONS: Early aggressive surgical management of suppurative complications of perianal Crohn's disease before complex management problems ensue results in a high incidence of healing and a low risk of subsequent proctectomy.

Conversion of the failing ileoanal pouch to reservoir-ileostomy rather than to ileostomy alone.

PURPOSE: We report the indications, technique, and results of conversion of the ileoanal pouch to the Kock's pouch in five patients. The indication was functional disturbance that could not be corrected by operation. Aim of the conversion operation was re-establishment of fecal control and complete preservation of existing ileal surface. METHODS: The ileal pouch was used again, and in one case an augmentation was made. The continence valve was made three times from the afferent loop and in two cases from a higher ileal segment. RESULTS: Following conversion, function was excellent in three patients with ulcerative colitis and in one patient with familial adenomatous polyposis. One woman who underwent proctocolectomy for slow-transit constipation needed a Brooke ileostomy for continuous abdominal distention pain. CONCLUSION: We conclude that conversion to a continent ileostomy is a rewarding method of safely eliminating dysfunction of the ileoanal pouch that cannot be corrected by operation. Presumption is, however, that the surgeon is familiar with both methods and that the primary disease is suitable for pouch surgery.

Functional outcome after low anterior resection with low anastomosis for rectal cancer using the colonic J-pouch. Prospective randomized study for determination of optimum pouch size.

PURPOSE: Functional outcome after low anterior resection with ultralow coloanal anastomosis for rectal cancer is improved by construction of a colonic J-pouch vs. straight anastomosis. Optimum size of this pouch has yet to be determined. Therefore, we initiated a prospective, randomized trial using 5-cm and 10-cm pouches to determine this size. METHODS: Patients with tumors 5 to 10 cm from the anal verge were included in the study. Before a low anterior resection anastomosis was performed, patients were randomized to either a 5-cm J-pouch group (5-J group) or a 10-cm J-pouch group (10-J group). Functional assessments were performed one year postoperatively. Clinical functions were evaluated using a functional scoring system. Physiologic functions, such as sphincter and reservoir function, were evaluated by anorectal manometry and evacuation function by the balloon expulsion and saline evacuation tests. RESULTS: Forty patients among 43 randomized patients were assessed for functional outcome one year postoperatively (5-J group, n = 20; 10-J group, n = 20). The functional score was similar for the two groups, although reservoir function in the 5-J group was significantly less than in the 10-J group. Sphincter function was similar between the two groups. Evacuation function in the 5-J group was significantly superior to that in the 10-J group. CONCLUSIONS: The 5-cm J-pouch conferred adequate reservoir function without compromising evacuation.

Analysis of regional lymph node metastases from rectal carcinoma by the clearing method. Justification of the use of sigmoid in J-pouch construction after low anterior resection.

PURPOSE: It has been reported that functional outcome following low anterior resection of resection of rectal cancer is improved by construction of a colonic J-pouch compared with straight anastomosis. Hence, we tried to justify use of the sigmoid colon in the construction of a J-pouch by the analysis of regional lymph node metastases. METHODS: A total of 182 patients underwent resection for rectal cancer. Node metastases were examined by the clearing method. According to Japanese General Rules for Clinical and Pathological Studies on Cancer of the Colon, Rectum and Anus (JGR), nodes were classified into the perirectal nodes (PR-N), pericolic nodes (PC-N), central intermediate nodes (C-IM-N), central main nodes (C-M-N), lateral intermediate nodes (L-IM-N), and lateral main nodes (L-M-N). RESULTS: Metastatic rate (number of patients with node metastases/total number of patients) of PR-N was 57.1 percent. Metastatic rate of C-IM-N was 18.7 percent and that of C-M-N was 7.1 percent. Metastatic rates of L-IM-N and L-M-N were 8.8 and 3.3 percent, respectively, and both were highest in the case of lower rectal cancer. Metastatic rate of PC-N was only 1.1 percent. The number of cases without node metastases (n(-) cases) was 78, that with only PR-N metastases (PR-N cases) was 63, that with intermediate but not main node metastases (IM-N cases) was 29, and that with main node metastases (M-N cases) was 12. Five-year survival rate after curative resection was 88.5 percent for n(-) cases, 70.9 percent for PR-N cases, 65.9 percent for IM-N cases, and 41.7 percent for M-N cases. CONCLUSIONS: In low anterior resection, high ligation of the inferior mesenteric artery and dissection of C-M-N, C-IM-N and PR-N are necessary, with the addition of the L-IM-N and L-M-N in the case of lower rectal cancer. Resection of sigmoid colon is not required, and therefore, a J-pouch can be constructed using the sigmoid colon. Nodal classification according to the JGR was predictive of case distribution and five-year survival rate.

Colonic J-pouch rectal reconstruction--is it really a neorectum?

PURPOSE: The aim of this study was to determine whether a colonic J-pouch has similar properties to that of a normal rectum, including recovery of rectoanal coordination. METHODS: Ten patients with colonic J-pouch-anal anastomosis (anastomotic distance from anal verge, 3.5 (range, 2.0-4.5) cm for low rectal cancer (7 men; mean age, 64.7 (range, 44-76) years) were studied clinically and in the anorectal physiology laboratory at least one year after operation. Results were compared with a series of ten matched patients who underwent high anterior resection for upper rectal carcinoma (anastomotic height, 12.7 (range, 9.5-16) cm). RESULTS: Although results seemed to be slightly better in the group with the rectum preserved, no statistical differences could be found either in functional outcome or anorectal physiology. One-half of the patients with colonic J-pouch (neorectum) had a positive rectoanal inhibitory reflex. CONCLUSION: Addition of a colon pouch neorectum would appear to improve function to the level of those patients with a high anastomosis and "normal" rectum.

Prediction of optimum dimensions of colonic pouch reservoir.

PURPOSE: A mathematic model was developed to quantify colonic reservoir pouch capacity and to allow comparison with capacity of the parent colonic segment from which the pouch was fashioned. METHODS: Using geometry, pouch capacity was calculated and various capacities were enumerated. RESULTS: From this model, ideal pouch dimensions can be predicted, which are 6 to 7 cm of undistended bowel circumference with limb lengths of 8 to 10 cm. CONCLUSIONS: Such a pouch maximizes the pouch colon capacity ratio and has a calculated undistended capacity between 60 and 105 ml.

What happens to a pelvic pouch when a fistula develops?

PURPOSE: The aim of this article is to determine the outcome of the pelvic pouch after the occurrence of a fistula. MATERIALS AND METHODS: From 1983 to 1995, 1,040 pelvic pouch surgeries were done at our institution. We reviewed the records of all patients with pouch-related fistulas. Data were collected from chart reviews and our pouch registry. RESULTS: Among 59 patients (22 males) with fistulas, mean age was 33 (range, 19-57) years. Preoperative diagnosis was mucosal ulcerative colitis (n = 52), indeterminate colitis (n = 6), and familial polyposis (n = 1). Site of fistulas included pouch/vaginal (n = 24), pouch/ cutaneous (n = 11), pouch/perineal (n = 16), and pouch/ presacral (n = 8). Postoperative diagnosis was mucosal ulcerative colitis (n = 40), Crohn's disease (n = 14), indeterminate colitis (n = 4), and familial polyposis (n = 1). One hundred eleven (range, 1-7) surgeries for treatment were performed. At a mean follow-up of 26 (range, 1-121) months, 19 pouches (32 percent) had been excised, 34 patients had functioning pouches and no fistula, 5 patients had a closed fistula but refused ileostomy closure, and 1-patient had died of unrelated causes (but the fistula was closed). Pouch type and preoperative diagnosis did not statistically affect pouch failure rates (P = 0.43 and 0.10. respectively). CONCLUSION: Successful treatment of fistula from a pelvic pouch can be achieved in more than 60 percent of patients. However, multiple procedures may be needed for a successful outcome. Ultimately, 32 percent had their pouches excised.

Afferent limb obstruction complicating ileal pouch-anal anastomosis.

PURPOSE: Small-bowel obstruction is a common complication after ileal pouch-anal anastomosis (IPAA). Acute angulation of the afferent limb at the pouch inlet is the cause of obstruction in a subset of patients requiring laparotomy. METHODS: Patients were identified from the Lahey Clinic ileoanal pouch registry, a prospective computerized database of all patients who have undergone IPAA since 1980. Records of patients who were identified as having afferent limb obstruction as a cause of bowel obstruction after IPAA were reviewed. RESULTS: A total of 567 patients had undergone total proctocolectomy and ileoanal J-pouch at time of the study. Of 122 patients with one or more episodes of obstruction after IPAA, 48 required operative intervention. Afferent limb obstruction was identified as the cause of obstruction in six patients (12 percent). The most common presentation was recurrent partial obstruction (4 of 6 patients). Contrast small-bowel series and enemas were suggestive of obstruction in four of six patients, the most consistent radiographic finding being small-bowel dilation to the level of the pouch inlet. All patients underwent laparotomy for unresolved obstruction. Intraoperatively, the afferent limb was found to be adherent posterior to the pouch, causing acute angulation at the pouch inlet. Rather than risk injury to the pouch or its mesentery, the obstruction was bypassed by side-to-side anastomosis of the afferent limb to the pouch (enteroenterostomy) in five of six patients. One patient underwent ileostomy only because of technical considerations. Two patients required re-exploration and pexy of the afferent limb to the pelvic sidewall (pouchopexy) to relieve recurrent afferent limb obstruction. CONCLUSION: Afferent limb obstruction should be suspected in patients with recurrent obstruction after IPAA. Bypass of the obstructed segment from distal ileum to the pouch is safe and effective treatment. Because of the risk of recurrent afferent limb angulation, concurrent pouchopexy should be considered.
