Function and quality of life results after ileal pouch surgery for chronic ulcerative colitis and familial polyposis

A Systematic Review: The Management and Outcomes of Ileal Pouch Strictures

BACKGROUND

Restorative proctocolectomy with ileal pouch-anal anastomosis removes the diseased tissue in ulcerative colitis but also allows gastrointestinal continuity and stoma-free living. Pouch strictures are a complication with a reported incidence of 5-38%. The three areas where pouch strictures occur are in the pouch inlet, mid-pouch and pouch-anal anastomosis.

AIM

To undertake a systematic review of the literature and to identify management strategies available for pouch-anal, mid-pouch and pre-pouch ileal strictures and their outcomes.

METHODS

A computer-assisted search of the online bibliographic databases MEDLINE and EMBASE limited to 1966 to February 2016 was performed. Randomized controlled trials, cohort studies, observational studies and case reports were considered. Those where data could not be extracted were excluded.

RESULTS

Twenty-two articles were considered eligible. Pouch-anal strictures have been initially managed using predominately dilators which include bougie and Hegar dilators with various surgical procedures advocated when initial dilatation fails. Mid-pouch strictures are relatively unstudied with both medical, endoscopic and surgical management reported as successful. Pouch inlet strictures can be safely managed using a combined medical and endoscopic approach.

CONCLUSION

The limited evidence available suggests that pouch-anal strictures are best treated in a stepwise fashion with initial treatment to include digital or instrumental dilatation followed by surgical revision or resection. Management of mid-pouch strictures requires a combination of medical, endoscopic and surgical management. Pouch inlet strictures are best managed using a combined medical and endoscopic approach. Future studies should compare different treatment modalities on separate stricture locations to enable an evidenced-based treatment algorithm.

Emergency total proctocolectomy in an uninsured patient with Familial Adenomatous Polyposis Syndrome and acute lower gastrointestinal hemorrhage in a community hospital: A case report

•

FAP is initially managed with genetic testing, followed by yearly colonoscopy from 10 to 40 years of age.

•

Once diagnosed, total proctocolectomy with ileal-J pouch to anal anastomosis is recommended.

•

The ultimate treatment for FAP patients presenting with acute lower GI hemorrhage and hemodynamic compromise is unclear.

•

This is the first literature report of an emergency total proctocolectomy for lower GI hemorrhage in an uninsured patient with FAP in a community hospital.

•

It is essential to monitor the ileo-anal anastomosis with anoscopy.

Introduction

Rectal bleeding is the most common symptom of Familial Adenomatous Polyposis (FAP). This case investigates the efficacy of emergency surgery for FAP with total proctocolectomy end ileostomy for recurrent lower gastrointestinal (GI) hemorrhage in an uninsured patient in a 266-bed community hospital. The optimal treatment for FAP with acute lower GI hemorrhage and hemodynamic compromise unresponsive to conservative management is unclear.

Presentation of case

A 41-year-old uninsured African American man with no past medical or family history presented to the emergency department with hematochezia lasting three days. A clinical diagnosis of FAP made on colonoscopy with biopsies revealed villous and tubulovillous adenomas without dysplasia. After blood products resuscitation, an emergency total proctocolectomy with end ileostomy was performed. A staged ileal J pouch to anal anastomosis and creation of protective loop ileostomy was performed months later after securing state funding. A final loop ileostomy reversal occurred six weeks later. His self reported quality of life is improved.

Discussion

Lower GI hemorrhage from FAP unresponsive to blood products may require emergency total proctocolectomy and end ileostomy with a staged ileal J pouch to anal anastomosis, which can be done in a community acute care hospital for an uninsured patient.

Conclusion

A total proctocolectomy is feasible in the emergency setting in an uninsured patient with lower GI bleeding and FAP. A staged ileal J pouch-anal anastomosis is easier to justify to the hospital compared to a staged completion colectomy with proctectomy. It is essential to monitor the ileo-anal anastomosis with anoscopy.

Functional and manometric outcomes after redo-ileal pouch anal anastomosis in patients with ulcerative colitis

AIM

To retrospectively analyze manometric findings in patients with ulcerative colitis who underwent redo-ileo anal anastomosis for pouch-related complications.

METHODS

Functional and anal manometric parameters were analyzed before, immediately after, and 6 months after the procedure in 17 patients who underwent redo-ileo anal anastomosis between 2001 and 2012.

RESULTS

Of the 17 patients, 13 showed stoma closure and 9 have maintained gastrointestinal continuity with functional pouches. Manometric findings were similar before and immediately after redo-ileo anal anastomosis, including length of high-pressure zone (p = 0.11) and maximum resting and (p = 0.060) squeezing (p = 0.69) pressures, but maximum resting pressure improved significantly 6 months later (p = 0.021). Univariate analysis showed that ulcerative colitis duration <3 years before ileo anal anastomosis (p = 0.0073), interval between pouch-related complications and ileo anal anastomosis <2 years (p = 0.040), and persistent abscess before diversion ileostomy (p = 0.0024) were significant risk factors for pouch failure after redo-ileo anal anastomosis.

CONCLUSIONS

Although maximum resting pressure was significantly reduced 3 months after redo-ileo anal anastomosis, it returned to preoperative levels after 6 months. The length of the high-pressure zone and the maximum squeezing pressure were not affected by this procedure.

Prevention of postoperative peritoneal adhesions: a review of the literature

BACKGROUND

postoperative adhesions are a significant health problem with major implications on quality of life and health care expenses. The purpose of this review was to investigate the efficacy of preventative techniques and adhesion barriers and identify those patients who are most likely to benefit from these strategies.

METHODS

the National Library of Medicine, Medline, Embase, and Cochrane databases were used to identify articles related to postoperative adhesions.

RESULTS

ileal pouch-anal anastomosis, open colectomy, and open gynecologic procedures are associated with the highest risk of adhesive small-bowel obstruction (class I evidence). Based on expert opinion (class III evidence) intraoperative preventative principles, such as meticulous hemostasis, avoiding excessive tissue dissection and ischemia, and reducing remaining surgical material have been published. Laparoscopic techniques, with the exception of appendicitis, result in fewer adhesions than open techniques (class I evidence). Available bioabsorbable barriers, such as hyaluronic acid/carboxymethylcellulose and icodextrin 4% solution, have been shown to reduce adhesions (class I evidence).

CONCLUSIONS

postoperative adhesions are a significant health problem with major implications on quality of life and health care. General intraoperative preventative techniques, laparoscopic techniques, and the use of bioabsorbable mechanical barriers in the appropriate cases reduce the incidence and severity of peritoneal adhesions.

The incidence and risk factors of post-laparotomy adhesive small bowel obstruction

INTRODUCTION

The purpose of this review was to assess the incidence and risk factors for adhesive small bowel obstruction (SBO) following laparotomy.

METHODS

The PubMed database was systematically reviewed to identify studies in the English literature delineating the incidence of adhesive SBO and reporting risk factors for the development of this morbidity.

RESULTS

A total of 446,331 abdominal operations were eligible for inclusion in this analysis. The overall incidence of SBO was 4.6%. The risk of SBO was highly influenced by the type of procedure, with ileal pouch-anal anastomosis being associated with the highest incidence of SBO (1,018 out of 5,268 cases or 19.3%), followed by open colectomy (11,491 out of 121,085 cases or 9.5%). Gynecological procedures were associated with an overall incidence of 11.1% (4,297 out of 38,751 cases) and ranged from 23.9% in open adnexal surgery, to 0.1% after cesarean section. The technique of the procedure (open vs. laparoscopic) also played a major role in the development of adhesive SBO. The incidence was 7.1% in open cholecystectomies vs. 0.2% in laparoscopic; 15.6% in open total abdominal hysterectomies vs. 0.0% in laparoscopic; and 23.9% in open adnexal operations vs. 0.0% in laparoscopic. There was no difference in SBO following laparoscopic or open appendectomies (1.4% vs. 1.3%). Separate closure of the peritoneum, spillage and retention of gallstones during cholecystectomy, and the use of starched gloves all increase the risk for adhesion formation. There is not enough evidence regarding the role of age, gender, and presence of cancer in adhesion formation.

CONCLUSION

Adhesion-related morbidity comprises a significant burden on healthcare resources and prevention is of major importance, especially in high-risk patients. Preventive techniques and special barriers should be considered in high-risk cases.

Restorative proctectomy with ileal pouch-anal anastomosis in obese patients

PURPOSE

The aim of this study was to assess outcomes of ileal pouch-anal anastomosis in obese patients compared with a matched cohort of nonobese patients.

METHODS

A review of all obese patients who underwent ileal pouch-anal anastomosis from 1998 to 2008 was performed. Obesity was defined as body mass index >or=30 kg/m. A matched control group of patients with body mass index within 18.5 to 25 kg/m was created. Primary end points included operative time, length of hospital stay, operative blood loss, and early (<or=6 wk) and long-term (>6 wk) postoperative complications.

RESULTS

Sixty-five obese patients (mean body mass index, 34.3 +/- 0.51 kg/m) underwent proctectomy with ileal pouch-anal anastomosis or proctocolectomy with ileal pouch-anal anastomosis. Mean body mass index of the control group was 22.45 +/- 0.2 kg/m (P < .0001). The most common diagnosis was mucosal ulcerative colitis (84.6%), followed by familial adenomatous polyposis (13.9%) and Crohn's disease (1.5%). The obese population had a higher incidence of cardiorespiratory comorbidities (P = .044), and a trend for steroid and immunosuppressive therapy (P = .06) preoperatively. Obese patients required longer operative time (P = .001) and longer hospital stay (P = .009). Early postoperative complications were comparable (P > .05). Long-term outcomes were also similar, except for a higher incidence of incisional hernia in the obese group (P = .01).

CONCLUSIONS

The overall postoperative complication rate in obese patients undergoing ileal pouch-anal anastomosis was similar to a matched nonobese cohort of patients. However, longer operative time, longer length of stay, and a higher rate of incisional hernia were noted in the obese population. Obese patients should be appropriately consulted about these issues before undergoing ileal pouch-anal anastomosis.

Abdominal Surgery Impact Scale (ASIS) is responsive in assessing outcome following IPAA

PURPOSE

Various generic and disease-specific quality of life instruments are available to assess outcome following surgery. However, they may not be sensitive to changes in outcome in the early postoperative period, which is important when assessing changes in surgical technique and perioperative care. The Abdominal Surgery Impact Scale (ASIS) is a validated instrument designed to assess short-term outcome following surgery. Thus, the aims of this study were to assess the impact of surgery on patients undergoing ileal pouch anal anastomosis (IPAA), assess factors which might impact on outcome, and lastly, further evaluate the reliability and internal consistency of the ASIS.

METHODS

Patients over the age of 18 who had an IPAA between March 2005 and October 2007 completed the ASIS on postoperative day 3 and at the time of discharge. The ASIS contains 18 items within six domains with possible scores ranging from 18 to 126. Demographic, clinical and surgical data, postoperative complications, and length of stay were also recorded. Internal reliability of the ASIS was measured using Cronbach's alpha coefficient.

RESULTS

Ninety-two patients (36 female, 56 male, mean age = 36.8 +/- 10.8) completed the ASIS at two time intervals (mean 3 days and mean 7 days postoperatively). Forty-seven patients had an IPAA performed with an ileostomy; 11 patients had the IPAA performed laparoscopically. The mean hospital stay was 10.8 days. The overall mean ASIS score significantly increased over the two time periods (mean 56.9 +/- 18.3 vs. 81.8 +/- 17.3, p < 0.001). Patients who had an ileostomy had a significantly lower mean score at discharge (77.32 vs. 86.82), secondary to lower scores on the physical limitations, functional impairment, and visceral function domains. Seven (7.8%) patients had ileo-anal anastomotic leaks, and seven (7.8%) patients had small bowel obstructions. These patients had an increased length of stay, whereas patients having laparoscopic surgery had a significantly shorter length of stay (8.8 days vs. 11.1 days), but there was no significant difference in mean ASIS scores. Cronbach's alpha coefficient was 0.94 overall and ranged from 0.69 to 0.91 for subscales indicating internal reliability.

CONCLUSIONS

ASIS is a valid instrument for measuring quality of life in the postoperative period and is responsive to changes over time. Although quality of life increases postoperatively during hospital stay, at discharge, patients with IPAA still have decreased quality of life. Patients with ileostomies have further decreased scores.

Quality of life in the late follow-up of ulcerative colitis patients submitted to restorative proctocolectomy with sphincter preservation over ten years ago

OBJECTIVE

To evaluate, by means of the Inflammatory Bowel Disease Questionnaire (IBDQ), the quality of life of ulcerative colitis patients submitted to proctocolectomy with sphincter preservation using J-pouch reconstruction over ten years ago.

METHODS

The study consisted of 36 patients interviewed using the Inflammatory Bowel Disease Questionnaire. The score scale, resulting from the addition of each answer, ranged from 32 to 224, where the highest score indicates the best quality of life. The chi square test was used to verify the existence of meaningful differences between the results of the questionnaire and age, and gender proportion. For each section, as well as for all of them combined, the Kruskal-Wallis test was used to verify if there were differences in the Inflammatory Bowel Disease Questionnaire scores among the groups in relation to the proportions.

RESULTS

After applying the Inflammatory Bowel Disease Questionnaire, it was determined that quality of life was considered excellent for 9 (25%), good for 11 (30.6%), regular for 13 (36.1%), and bad for 3 (8.3%) patients. In our study, we determined that 85% of the patients were pleased with and thankful for the surgery that they underwent.

CONCLUSION

We can conclude that the possibility of sphincter preservation should always be taken into account, since patients remain clinically stable and have a high quality of life even after long periods.

Hospital readmission rates after ileal pouch-anal anastomosis

PURPOSE

The goal of this study was to determine the unplanned hospital readmission rate following ileal pouch-anal anastomosis, prior to loop ileostomy closure.

METHODS

Patients undergoing ileal pouch-anal anastomosis over a five-year period were included in this retrospective study. Unplanned readmissions and readmission diagnoses were compiled. Gender, age, type of disease, duration of illness, elective vs. urgent surgical indication, operative method, steroid use, American Society of Anesthesiologists score, and regional anesthesia use at initial ileal pouch-anal anastomosis were evaluated as potential factors for readmission. Total length of stay was compared between patients readmitted and not readmitted.

RESULTS

One hundred and ninety-five patients underwent ileal pouch-anal anastomosis with diverting ileostomy. Fifty-nine patients (30 percent) required readmission. Forty-one patients had a single readmission, and 18 patients had at least 2 readmissions. Small bowel obstruction (28/86) and pelvic sepsis/ anastomotic leak (28/86) were the most common diagnoses upon readmission. Seventeen of 59 patients (28.8 percent) required surgical intervention following readmission and 42 patients were managed nonoperatively. Patients using systemic steroids at the time of surgery were more likely to be readmitted [47/116 (41 percent) vs. 12/79 (15 percent), P = 0.001). Length of stay (including initial admission for ileal pouch-anal anastomosis) for patients requiring readmission averaged 19.6 days vs. 9.6 days for patients not readmitted.

CONCLUSIONS

Hospital readmission after ileal pouch-anal anastomosis is common. We plan to institute a more intensive follow-up in an effort to prevent readmission of selected high-risk patients who might be effectively managed as outpatients.

Adhesions are common and costly after open pouch surgery

PURPOSE

Open ileal pouch surgery leads to high rates of adhesive small-bowel obstruction (SBO). A laparoscopic approach may reduce these complications. We aimed to review the incidence of adhesive SBO-related complications after open pouch surgery and to model the potential financial impact of a laparoscopic approach purely as an adhesion prevention strategy.

MATERIALS AND METHODS

We reviewed cases of open ileal pouch patients kept on a database and examined annually. Case notes were studied for episodes of adhesive SBO requiring admission or reoperation. Similar parameters were studied in a small series undergoing laparoscopic pouch surgery. The financial burden of the open access complications was estimated and potential financial impact of a laparoscopic approach modeled.

RESULTS

Two hundred seventy-six patients were followed up after open surgery (median, 6.3; range, 0.2-20.1 years). There were 76 (28%) readmissions (median length of stay, 7.4 days) in 53 patients (19%) and 28 (10%) reoperations (43% within 1 year). Laparoscopic patients required less adhesiolysis at second-stage surgery (0% vs 36%, p < 0.0001) and had less SBO episodes within 12 months of surgery (0% vs 14%, p < 0.0001) than open patients. Modeling a laparoscopic approach cost $1,450 and saved $3,282, thus netting $1,832 per pouch constructed.

CONCLUSION

Open ileal pouch surgery results in significant cumulative long-term access-related complications, particularly adhesions. These impose a large medical burden on patients and financial burden on health-care systems, all of which may be recouped by a laparoscopic approach, despite higher theater costs.

Complicações imediatas e tardias após cirurgia de reservatório ileal na polipose adenomatosa familiar

RACIONAL: A retocolectomia total com confecção de reservatório ileal é cirurgia ideal para o tratamento do cólon e reto dos doentes com polipose adenomatosa familiar, no entanto pode estar associada a complicações no pós-operatório imediato e tardio. OBJETIVO: Estudar as complicações pós-operatórias da cirurgia do reservatório ileal na polipose adenomatosa familiar. MÉTODOS: Estudo retrospectivo de 69 doentes com polipose adenomatosa familiar submetidos a cirurgia de reservatório ileal no período de 1984 a 2006, pelo Grupo de Coloproctologia da Faculdade de Ciências Médicas da Universidade Estadual de Campinas, SP. O seguimento médio pós-operatório foi de 82 (2-280) meses. Dados de interesse: ocorrência de complicações no pós-operatório. RESULTADOS: A morbidade e mortalidade foram de 63,8% e 2,9%, respectivamente. As complicações mais freqüentes foram obstrução intestinal (17,4%), estenose da anastomose (15,9%) e sepse pélvica (10,1%). Outras complicações foram isquemia aguda do reservatório ileal (4,3%), ileíte do reservatório (" pouchitis" ) (2,9%) e fístulas relacionadas ao reservatório (2,9%). CONCLUSÕES: A morbimortalidade foi semelhante à da literatura e aceitável para uma cirurgia complexa como é a do reservatório ileal, realizada em dois tempos operatórios. A obstrução intestinal foi a complicação mais freqüente. Entretanto, isquemia do reservatório, " pouchitis" e sepse pélvica constituíram importantes complicações relacionadas à perda do reservatório ileal.

Quality of life after indefinite diversion/pouch excision in ileal pouch failure patients

OBJECTIVE

Pouch failure occurs in up to 10% of patients over a 10-year period for a variety of reasons. One surgical option is pouch excision (PE) and form a permanent ileostomy. This is a major procedure with potential serious complications. An alternative is indefinite diversion (ID) of the pouch without excision. The aim of this study was to examine the quality of life and functional outcome in these two groups of patients.

METHOD

Ninety-seven patients were identified from the database to have either PE or ID. Fifty-three patients (17 men) responded; comprising 31 patients after PE and 22 patients with ID in a case-control study and completed the SF-36 general health survey and the Cleveland Clinic Foundation (CCF) functional outcomes questionnaire.

RESULTS

There was no significant difference in the domains of SF-36 between the two groups (P > 0.18). All patients with PE had an end ileostomy whereas most patients with ID had a loop ileostomy (18 loop vs 4 end). There was no difference in stoma related complications except for stoma retraction in ID (7%vs 47%; P = 0.003). There was no significant difference in urinary symptoms between PE and ID groups (weak stream 26%vs 14%; P = 0.49, nocturia 22%vs 4%; P = 0.12, urgency 22%vs 9%; P = 0.28, urinary incontinence 22%vs 14%; P = 0.72 respectively). There was no difference in sexually active patients (73%vs 94%; P = 0.11). Of the seven male PE patients, five (71%) could achieve an erection and four (57%) could maintain an erection, compared with all 10 male patients in the ID group (P = 0.151 and 0.05 respectively). Thirty-three per cent of patients with PE and 62% of patients with ID reported that they would have pouch surgery again if indicated (P = 0.052) and 58% of patients with PE and 81% of patients with ID reported that they would recommend pouch surgery to others (P = 0.129). No case of dysplasia was seen in 18 of 22 ID patients in whom histology was available.

CONCLUSION

Quality of life after PE or ID was no different and male sexual function was significantly better after ID. Retraction of the stoma was more common in this group.

Implications of pouchitis on the functional results following stapled restorative proctocolectomy

PURPOSE

Pouchitis is the most frequent long-term complication of restorative proctocolectomy; its long-term consequences are inadequately described. This prospective study evaluates the effect of pouchitis on the functional results, general health perception, and patient satisfaction.

METHODS

A total of 100 consecutive patients who underwent stapled restorative proctocolectomy for ulcerative colitis were divided into three groups: no pouchitis, acute pouch-itis and chronic pouchitis. Functional results, general health perception, and satisfaction of each group at the latest review were compared only when patients were not symptomatic of active pouchitis.

RESULTS

Pouchitis occurred in 33 patients (17 acute and 16 chronic). There were no significant differences in the long-term functional results between the no pouchitis and acute pouchitis groups. Patients who experienced chronic pouchitis had a significant increase in bowel movements, looseness of stools, urgency, nocturnal seepage, perianal excoriation, and dietary restrictions (P < 0.05). They also had a worse perception of their general health (P < 0.05). Previous chronic pouchitis had no effect on continence, daytime soilage, or gas-feces discrimination. Most patients were satisfied, despite pouchitis, and would recommend the operation to someone else with ulcerative colitis.

CONCLUSIONS

Acute pouchitis is easily treated and results in minimal functional consequences. Even in the absence of clinically active pouchitis, patients who had suffered from chronic pouchitis had poorer functional results and general health perception. This may overshadow the benefits of restorative proctocolectomy. This finding suggests that acute and chronic pouchitis are distinct disease entities and chronic pouchitis may represent a persistent condition that displays episodic symptomatic exacerbation.

Pediatric ileal pouch-anal anastomosis: functional outcomes and quality of life

BACKGROUND/PURPOSE

The aim of this study was to assess and correlate functional outcomes and surgical results with health-related quality of life after ileal pouch-anal anastomosis (IPAA) in pediatric patients.

METHODS

Functional outcome was determined by questionnaire and telephone interview. Surgical results were determined by retrospective chart review.

RESULTS

Data were gathered from 26 patients (mean age at IPAA, 12 years; mean follow-up, 3.7 years). Diagnoses were ulcerative colitis in 18, indeterminate colitis in 4, and familial polyposis in 4. Indications for IPAA included intractability, medication toxicity, growth delay, and cancer prophylaxis. Short-term complications (5 patients; 19%) included partial small bowel obstruction, stomal revision, pouch abscess, and negative exploration. Long-term complications (8 patients; 31%) were chronic pouchitis and anal stricture. The average number of stools per 24 hours was 3.9. No incontinence was reported; dietary restrictions were negligible. Although there were minimal differences from population norms, parental anxiety remained high. Chronic pouchitis correlated negatively with physical summary score. Nocturnal stooling negatively affected psychosocial quality of life.

CONCLUSIONS

Pediatric IPAA resulted in excellent bowel health. Quality of life, physical function, mental health, and self-esteem were equivalent to those of healthy children. These data may help families and physicians make informed surgical decisions.

Reconstructive surgery for failed ileal pouch-anal anastomosis: a viable surgical option with acceptable results

PURPOSE

Salvage procedures for failed ileal pouch-anal anastomoses frequently require total reconstruction with a combined abdominal and perineal approach. The aim of this study was to determine the indications for surgery and the outcomes in this group of patients.

METHODS

All patients who underwent combined abdominal and perineal ileal pouch-anal anastomosis reconstruction at the Mount Sinai Hospital between 1982 and 2000 were reviewed. Data were collected prospectively in the inflammatory bowel disease database.

RESULTS

Sixty-three reconstructive procedures were performed in 57 patients, with a mean age of 33.9 (+/-10.4) years at the time of reconstruction. There were 14 males. The mean follow-up was 69.1 months. The initial indication for ileal pouch-anal anastomosis was ulcerative colitis in 98 percent. The primary indication for reconstruction was pouch-vaginal fistula in 21 patients, long outlet in 14, pelvic sepsis in 14, ileoanal anastomotic stricture in 5, pouch-perineal fistula in 2, and chronic pouchitis in 1. The mean operative time was four hours (+/-1.1), the average blood loss was 500 mL (+/-400), and the average length of stay was 10.3 days (+/-4.6). All patients had a diverting ileostomy. Forty-two (73.6 percent) of the patients have a functioning pouch. Seven (12.3 percent) patients have had their pouch excised. The ileostomy has not yet been closed in 8 (14 percent) patients; 3 of these patients are awaiting closure, whereas the remaining 5 have a permanently defunctioning ileostomy. Eighty-nine percent have ten or fewer bowel movements per day. No patients are incontinent of stool during the day, whereas two patients are incontinent at night. Seventeen percent complain of frequent urgency. Despite this, more than 80 percent rate their physical and psychological health as good to excellent.

CONCLUSION

Reconstructive pouch surgery has a high success rate in experienced hands. The functional results in those whose pouch is in use are good.

Risk of small bowel obstruction after the ileal pouch-anal anastomosis

OBJECTIVE

To determine the incidence of small bowel obstruction (SBO), to identify risk factors for its development, and to determine the most common sites of adhesions causing SBO in patients undergoing ileal pouch-anal anastomosis (IPAA).

METHODS

All patients undergoing IPAA at Mount Sinai Hospital were included. Data were obtained from the institution's database, patient charts, and a mailed questionnaire. SBO was based on clinical, radiologic, and surgical findings. Early SBO was defined as a hospital stay greater than 10 or 14 days because of delayed bowel function, or need for reoperation or readmission for SBO within 30 days. All patients readmitted after 30 days with a discharge diagnosis of SBO were considered to have late SBO.

RESULTS

Between 1981 and 1999, 1,178 patients underwent IPAA (664 men, 514 women; mean age 40.7 years). A total of 351 episodes of SBO were documented in 272 (23%) patients during a mean follow-up of 8.7 years (mean 1.29 episodes/patient). Fifty-four patients had more than one SBO. One hundred fifty-four (44%) of the SBOs occurred in the first 30 days; 197 (56%) were late SBOs. The cumulative risk of SBO was 8.7% at 30 days, 18.1% at 1 year, 26.7% at 5 years, and 31.4% at 10 years. The need for surgery for SBO was 0.8% at 30 days, 2.7% at 1 year, 6.7% at 5 years, and 7.5% at 10 years. In patients requiring laparotomy, the obstruction was most commonly due to pelvic adhesions (32%), followed by adhesions at the ileostomy closure site (21%). A multivariate analysis showed that when only late SBOs were considered, performance of a diverting ileostomy and pouch reconstruction both led to a significantly higher risk of SBO.

CONCLUSIONS

The risk of SBO after IPAA is high, although most do not require surgical intervention. Thus, strategies that reduce the risk of adhesions are warranted in this group of patients to improve patient outcome and decrease healthcare costs.

Impotence after mesorectal and close rectal dissection for inflammatory bowel disease

PURPOSE

Close rectal dissection is a surgical technique used by some surgeons in inflammatory bowel disease. It is performed within the mesorectum, close to the rectal muscle wall, with the aim of minimizing damage to the pelvic sexual nerves. Other surgeons dissect in the more anatomical mesorectal plane. Our aim was to determine whether close rectal dissection is more protective of the pelvic sexual nerves than mesorectal dissection.

METHOD

Patients undergoing surgery for inflammatory bowel disease were entered prospectively into a database. Male patients were mailed a standardized, validated, urologic impotence questionnaire: the International Index of Erectile Function.

RESULTS

There was an 81 percent response rate. Six of 156 assessable patients were totally impotent (3.8 percent). They were all in the 50-year-old to 70-year-old age group, with no impotence in patients younger than 50 years old. Twenty-one patients complained of minor diminution of erectile function (13.5 percent), where sexual activity was still possible. There was no statistical difference in the rate of complete (2.2 percent vs. 4.5 percent, P = 0.67) or partial (13.5 percent vs. 13.3 percent, P = 0.99) impotence between close rectal and mesorectal dissection (Fisher's exact test). There were no ejaculatory difficulties. The time elapsed since surgery ranged from 2.7 months to 192.7 months, with a median of 74.5 months.

CONCLUSION

Rectal excision for inflammatory bowel disease can be conducted with low rates of impotence. Minor degrees of erectile dysfunction may be more common than currently recognized. We could not demonstrate that close rectal dissection significantly protects the patient from impotence compared with operating in the anatomical mesorectal plane. Age appears to be the most important risk factor for postoperative impotence.

Anatomy of Denonvilliers' fascia and pelvic nerves, impotence, and implications for the colorectal surgeon

BACKGROUND

The development and anatomy of Denonvilliers' fascia have been controversial for many years and confusion exists about its operative appearance. Better appreciation of this poorly understood anatomy, and its significance for impotence after rectal dissection, may lead to further functional improvements in pelvic surgery.

METHOD

A literature review of the embryology and anatomy of Denonvilliers' fascia and impotence after pelvic rectal surgery was undertaken.

RESULTS

Denonvilliers' fascia has no macroscopically discernible layers. The so-called posterior layer refers to the fascia propria of the rectum. The incidence of erectile and ejaculatory dysfunction after rectal excision is high in older patients, and when performed for rectal cancer. There is no consensus about the relationship of Denonvilliers' fascia to the plane of anterior dissection for rectal cancer.

CONCLUSION

Colorectal surgeons should focus on the important anatomy between the rectum and the prostate to improve functional outcomes after rectal excision. A classification of the available anterior dissection planes is proposed. Surgeons should be encouraged to document the plane used as well as outcome in terms of sexual function.

Ileal pouch anal anastomosis without ileal diversion

OBJECTIVE

To evaluate continued experience with a one-stage stapled ileoanal pouch procedure without temporary ileostomy diversion.

SUMMARY BACKGROUND DATA

Most centers perform colectomy, proctectomy, and ileal pouch anal anastomoses (IPAA) with a protective ileostomy. Following a previous report, the authors performed 126 additional stapled IPAA procedures for ulcerative colitis and familial adenomatous polyposis, of which all but 2 were without an ileostomy. Outcomes in these patients question the need for temporary ileal diversion, with its complications and need for subsequent surgical closure.

METHODS

Two hundred one patients underwent a stapled IPAA since May 1989, 192 as a one-stage procedure without ileostomy, and 1 with a concurrent Whipple procedure for duodenal adenocarcinoma. Patient charts were reviewed or patients were contacted by phone to evaluate their clinical status at least 1 year after their surgery.

RESULTS

Among the patients who underwent the one-stage procedure, 178 had ulcerative colitis (38 fulminant), 5 had Crohn's disease (diagnosed after IPAA), 1 had indeterminate colitis, and 8 had familial adenomatous polyposis. The mean age was 38 +/- 7 (range 7--70) years; there were 98 male patients and 94 female patients. The average amount of diseased tissue between the dentate line and the anastomosis was 0.9 +/- 0.1 cm, with 35% of the anastomoses at the dentate line. With 89% follow-up at 1 year or more (mean 5.1 +/- 2.4 years) after surgery, the average 24-hour stool frequency was 7.1 +/- 3.3, of which 0.9 +/- 1.4 were at night. Daytime stool control was 95% and night-time control was 90%. Only 2.3% needed to wear a perineal pad. Average length of hospital stay was 10 +/- 0.3 days, with 1.5 +/- 0.5 days readmission for complications. Abscesses or enteric leaks occurred in 23 patients; IPAA function was excellent in 19 of these patients (2 have permanent ileostomies). In patients taking steroids, there was no significant difference in leak rate with duration of use (29 +/- 8 with vs. 22 +/- 2 months without leak) or dose (32 +/- 13 mg with vs. 35 +/- 3 mg without leak). Two (1%) patients died (myocardial infarction, mesenteric infarction).

CONCLUSIONS

The triple-stapled IPAA without temporary ileal diversion has a relatively low complication rate and a low rate of small bowel obstruction, provides excellent fecal control, permits an early return to a functional life, and can be performed in morbidly obese and older patients.

Functional outcome after restorative panproctocolectomy for ulcerative colitis decreases an otherwise enhanced quality of life

BACKGROUND

Restorative panproctocolectomy is a favoured operation for ulcerative colitis, but altered bowel habit may adversely affect overall quality of life.

METHODS

Specific and generic quality of life questionnaires and an instrument to award money for continuing disability based on government guidelines were sent to 103 patients who had curative surgery for ulcerative colitis between 1995 and 1997. Seventy-one patients returned completed questionnaires: 30 with an ileostomy (representing incontinence and abnormal body image), 11 with a Koch pouch (representing continence and abnormal body image) and 30 with a pelvic pouch (representing continence and normal body image).

RESULTS

Patients valued the disability of having an ileostomy similar to that for a Koch pouch or a pelvic pouch: pound 40 000, pound 30 000 and pound 40 000 respectively (P = 0. 97). There was no sex difference. Body image measured with a visual analogue scale (least = 1, worst = 10) was worst with the ileostomy and Koch pouch (8 each) and best with a pelvic pouch (5) (P = 0.06). However, pelvic pouches scored significantly worse than an ileostomy with regard to altered bowel emptying (pelvic pouch, 8; Koch pouch, 7; ileostomy, 5) (P = 0.01).

CONCLUSION

Poor function after pelvic pouch surgery offsets any advantage in body image over an ileostomy. Thus, overall quality of life and perceived monetary damage were the same for the two operations. Improved pelvic pouch function is likely to be reflected in better quality of life after restorative panproctocolectomy.

Health-related quality of life after ileal J-pouch-anal anastomosis for ulcerative colitis: long-term results

BACKGROUND

This questionnaire study examined associations between health-related quality of life and long-term follow-up results with J-pouch anal anastomosis for ulcerative colitis.

METHODS

A two-part questionnaire was sent to patients treated for ulcerative colitis by handsewn J-pouch-anal anastomosis at our institute in the period 1985-95. The health-related quality of life measurement was based on a RAND SF-36 Finnish version of the questionnaire. Scores were compared with the normal Finnish population. The functional status was analysed with a 34-item questionnaire on pouch function and incontinence.

RESULTS

The response rate was 62%. The median follow-up time was 8 years (3 to 13 years). Functional results were acceptable: median number of bowel movements per 24 h was six. Soiling at night occurred in 32%, and inability to differentiate pouch contents in 24% cases. Twenty-four per cent used a pad occasionally, and 9% every day. The functional score and the health-related quality of life score correlated strongly. Poor functional status and a history of chronic pouchitis were associated with lower score. The limiting value after which the score was lower was 10 bowel movements per 24 h in 16%. A compromised anal continence proved to decrease the health-related quality of life as well.

CONCLUSIONS

RAND SF-36 scores seem to provide a useful tool to evaluate the health-related quality of life after pelvic pouch operation for ulcerative colitis. Frequent bowel movements, impaired anal continence, and pouchitis are common in long-term follow-up after ileal pouch operation. The scores were, however, comparable to those in the normal population in terms of adaptation to daily life with a pelvic pouch.

Cumulative risk of developing polyps or malignancy at the ileal pouch-anal anastomosis in patients with familial adenomatous polyposis

Restorative proctocolectomy with an ileal pouch-anal anastomosis is performed in an increasing number of patients with familial adenomatous polyposis (FAP). Two techniques are currently used to construct an ileal pouch-anal anastomosis: (1) a double-stapled anastomosis between the pouch and the anal canal and (2) mucosectomy with a hand-sewn ileoanal anastomosis at the dentate line. Although this procedure is thought to abolish the risk of colorectal adenoma, an increasing number of case reports have been published concerning the development of adenoma at the anastomotic site. The purpose of this study was to evaluate the overall cumulative risk of developing adenomatous polyps after ileal pouch-anal anastomosis and to compare the cumulative risk after either anastomotic technique. A total of 126 consecutive FAP patients undergoing a restorative proctocolectomy were identified from polyposis registries in The Netherlands, Denmark, Italy, Germany, and New York. Life-table analysis was used to calculate the cumulative risk of developing polyps in 97 patients with at least 1 year of endoscopic follow-up (median 66 months, range 12 to 188 months). A double-stapled anastomosis was used in 35 patients, whereas in 62 patients a hand-sewn anastomosis with a mucosectomy was performed. In 13 patients polyps developed at the anastomotic site, four with severe and four with moderate dysplasia. None of the patients developed a carcinoma at the anastomotic site. The cumulative risk of developing a polyp at the anastomotic site was 8% (95% confidence interval 2% to 14%) at 3.5 years and 18% (95% confidence interval 8% to 28%) at 7 years, respectively. The risk of developing a polyp at the anastomotic site within 7 years was 31% for patients with a double-stapled vs. 10% for patients with a hand-sewn anastomosis with mucosectomy (P = 0.03 [log-rank test]). Because FAP patients undergoing a restorative proctocolectomy with either a double-stapled or hand-sewn anastomosis have a substantial risk of developing adenomatous polyps at the anastomotic site, lifelong endoscopic surveillance is mandatory in both groups.

Quality-of-life assessment after ileoanal pull-through for ulcerative colitis and familial adenomatous polyposis

BACKGROUND/PURPOSE

The ileoanal pull-through procedure (IAP) is gaining increasing favor and use in the surgical treatment of children with ulcerative colitis (UC) and familial adenomatous polyposis (FP). Although physiological studies have been performed to assess the outcome of these children, no long-term quality-of-life assessment after the procedure has been performed.

METHODS

Forty-three patients were identified who had an IAP at our institution in the last 10 years and were at least 6 months postsurgery. Thirty-four were contacted, and 32 agreed to participate in the survey, which was approved by the Human Studies Committee. Participants completed the standardized Medical Outcome Study Short Form-36 (SF-36), which has well-established normative values. Several supplemental questions were prepared in a similar format dealing with issues specific to the ileoanal pull-through procedure.

RESULTS

Of the 32 participants, 19 (59%) were girls and 26 (81%) had ulcerative colitis. Mean age at the time of survey was 18.1 years with 12 less than 18 years and 20 > or =18 years. Data from the latter group could be compared with national normative values for this age. The study group was not statistically different from age-appropriate US population normal values on all assessable scales of physical and mental health in the SF-36 survey including physical functioning, role limitations-physical, bodily pain, general health, vitality, social functioning, role limitations-emotional, and mental health (all P>.05 or mean difference SD units <0.8). The supplemental questionaire demonstrated little adverse effect of the surgery. There was limited consumption of medications to control bowel frequency and little restriction of activity because of the frequency of bowel movements or fear of incontinence. The surgical scar was the sole negative factor of significance.

CONCLUSIONS

The ileoanal pull-through procedure is an excellent surgical option for children with ulcerative colitis or familial adenomatous polyposis, and it produced minimal, if any, adverse effects on their long-term quality of life.

Quality of life in patients with benign anorectal disorders

BACKGROUND

Benign proctological conditions are very common in Western civilization. However, to date quality of life in these patients has not been evaluated comprehensively. The aim of this study was to investigate whether the Gastrointestinal Quality of Life Index (GIQLI) is a useful instrument for measuring quality of life in these patients, and subsequently to establish baseline values for different anorectal disorders.

METHODS

The questionnaire was completed by 325 consecutive patients (182 men; mean age 49 years) seen at the proctology outpatient clinic. For further analysis patients were classified into nine subgroups according to the primary diagnosis: group 1, haemorrhoids (n=96); group 2, anal fissure (n=38); group 3, fistula in ano (n=22); group 4, severe constipation (n=14); group 5, faecal incontinence (n=35); group 6, symptomatic anterior rectocele (n=12); group 7, perianal abscess (n=7); group 8, perianal thrombosis (n=7); and group 9, miscellaneous conditions (e.g. skin tags, anal papillomas, mild constipation, rectal polyps) (n=94). The GIQLI scores were compared between the subgroups. In addition the GIQLI scores of age-matched healthy controls, derived from data in the literature, were compared with the patients' scores.

RESULTS

The mean GIQLI score for all patients was 113 (78.5 per cent of the maximum score of 144). Mean scores for the nine diagnostic subgroups were: group 1, 120; group 2, 104; group 3, 119; group 4, 94; group 5, 93; group 6, 112; group 7, 115; group 8, 129; and group 9, 117. Age-matched controls from a series published previously had a significantly higher GIQLI score compared with all patients (P < 0.0001). However, only the subgroups of patients with miscellaneous conditions, fissures, severe constipation and faecal incontinence had a significantly poorer quality of life than age-matched healthy individuals.

CONCLUSION

The GIQLI is a valuable instrument for measuring quality of life in patients with benign anorectal disorders. Although certain diseases do not seem to affect quality of life profoundly, certain subgroups of patients, most notably those with incontinence and severe constipation, are extremely compromised. Severely constipated individuals exhibit the same poor quality of life as patients with faecal incontinence.

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.

Functional results after perineal complications of ileal pouch-anal anastomosis

PURPOSE

This study investigated the functional significance of perineal complications after ileal pouch-anal anastomosis.

METHODS

Review of a prospective registry of 628 patients was undertaken. Bowel function was assessed by detailed functional questionnaire. Statistical analyses were performed using chi-squared and Fisher's exact probability tests.

RESULTS

Of 628 patients, 153 (24.4 percent) had 171 perineal complications. The 277 control patients had no complications. Complications included 66 (10.5 percent) anastomotic strictures, 28 (4.5 percent) anastomotic separations, 36 (5.7 percent) pouch fistulas, 41 (6.5 percent) episodes of pelvic sepsis, and 18 (2.9 percent) patients with multiple complications. After these complications were addressed, the pouch failure rate was low (10 percent); in 90 percent of patients, the pouch could be salvaged. Most pouch failures were the result of pouch fistulas, and most occurred in patients ultimately diagnosed with Crohn's disease. Functional results after cure of these perineal complications revealed no significant functional differences between control patients and those cured of anastomotic separations, anastomotic strictures, and pouch fistulas. Only a few minor differences were demonstrated in function after an episode of pelvic sepsis. The major deterioration in function occurred after treatment for multiple perineal complications.

CONCLUSIONS

An appreciable number of perineal complications occur after ileal pouch-anal anastomosis. Pouch-perineal fistulas are associated with the highest pouch failure rate. The majority of these fistulas occur in patients ultimately diagnosed with Crohn's disease or indeterminate colitis. Although there is no substitute for good technique and sound clinical judgment in the success of ileal pouch-anal anastomosis, if perineal complications are successfully treated, functional outcome is equivalent to that in patients without perineal complications.

Functional results after restorative proctocolectomy complicated by pouchitis

This study aimed to examine the incidence and cumulative risk of pouchitis after restorative proctocolectomy for ulcerative colitis and to evaluate the clinical and functional results in patients with pouchitis.

METHODS

A total of 291 patients had proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis between January 1985 and January 1996. During follow-up, 65 patients had one or more episodes of pouchitis based on clinical, histologic, and endoscopic criteria. Functional results and patient satisfaction in these patients were compared with those of 65 matched control patients who had experienced no episodes of pouchitis.

RESULTS

Pouchitis developed in 65 patients (22 percent), giving rise to a cumulative frequency of 28 percent at 11 years after the operation. Only 13 patients (4.5 percent) had chronic pouchitis that required long-lasting treatment. A permanent ileostomy had to be constructed in one patient (0.3 percent) because of pouchitis. During the last year (1995), 60 percent of patients with pouchitis had medication, most often metronidazole and/or corticosteroids. Defecation frequency per 24 hours was 6.7 for all patients with pouchitis, 8.2 for those with chronic pouchitis (P < 0.05), and 6.3 for patients without pouchitis. Nighttime defecation occurred in 44 (80 percent) patients with pouchitis, compared with 37 (67 percent) of those without pouchitis (P > 0.05). Frequencies of soiling or flatus incontinence did not differ between the two groups. During the last year, 43 (80 percent) of the pouchitis patients, who answered the questionnaire, were working all the year or were on sick-leave less than one month.

CONCLUSIONS

Episodic pouchitis is easily treated and causes minimum functional consequences, whereas chronic pouchitis increases defecation frequency and needs prolonged medication. Pouchitis seems not to be a major threat to preventing the use of restorative proctocolectomy in ulcerative colitis, but still the small group of chronic pouchitis patients remains a problem.

Ileoanal pouch in the active duty population: effect on military career

Patients undergoing proctocolectomy with an ileal pouch-anal anastomosis (IPAA) are reported to have an improvement in lifestyle and are able to return to their previous occupation. We questioned whether this was also true of active duty military personnel who require this operation. The rigors of military service are unlike that of most civilian occupations. Soldiers must maintain a physical fitness regimen and remain eligible to deploy overseas. We reviewed our experience with IPAA to determine whether our active duty patients could return to full duty.

METHODS

The charts of all patients undergoing IPAA since October 1990 were reviewed, and each patient was interviewed by telephone to elicit late complications not noted in their medical records and to inquire about their present bowel function. Patients were classified as active duty or nonactive duty. Active duty patients were queried as to whether they have remained on active duty, have required a permanent profile, have been promoted, or have been deployed overseas. If a military medical evaluation board had determined whether they were fit for duty, the findings of the board were reviewed.

RESULTS

Thirty-four patients underwent an IPAA; 15 were active duty. Mean follow-up was 24 months. Indication for IPAA was ulcerative colitis in 76 percent of patients and familial adenomatous polyposis in 24 percent. J-Pouch was created in 88 percent of patients. Mean bowel movement frequency was seven per day, and 84 percent could defer a bowel movement for more than one hour. Leakage requiring a pad was reported by three patients (9 percent). Seven of 15 active duty patients (47 percent) remained on active duty, and 3 have been promoted. Of the eight patients who were evaluated by a medical evaluation board and were retired, only four were found unfit because of poor bowel function. Therefore, if it were not for other physical limitations, 11 of 15 (73 percent) active duty patients could have continued to serve.

CONCLUSIONS

Barring other disqualifying illnesses, active duty soldiers can anticipate continuation of their military career following IPAA. Active duty soldiers, if motivated, can excel and maintain their status in the military.

Effect of intervention in inflammatory bowel disease on health-related quality of life: a critical review

Health-related quality of life (HRQOL) is a quantitative measurement of subjective perception of health state, including emotional and social aspects. It can be reliably measured with several valid instruments. Previous reviews of the literature suggested inadequate attention to HRQOL in studies of interventions in inflammatory bowel disease.

PURPOSE

This study was undertaken to assess the current status of the quality of measurement of HRQOL in studies of inflammatory bowel disease and to review the clinical conclusions warranted by the literature.

METHOD

Medicine was searched for articles relating to ulcerative colitis, Crohn's disease, or inflammatory bowel disease and quality of life since 1981. The articles found were reviewed for citations of further articles. The adequacy of HRQOL measure was assessed and graded, and the study design was categorized to assess the strength of the literature on the whole.

RESULTS

A trend was found toward higher quality of HRQOL measurement in the period 1988 to 1994 compared with 1981 to 1987. Most of the improvement was because of increased use of standardized and multidomain but unvalidated and unpublished questionnaires for measurement.

CONCLUSIONS

Confidence in the following clinical conclusions in studies of surgical interventions in inflammatory bowel disease is limited by study design: that pelvic pouch is not inferior to ileostomy, that specific domains of HRQOL are differentially affected by different surgical procedures, and (with less confidence) that surgery is helpful in Crohn's disease. Medical studies have demonstrated that high quality HRQOL measures can be integrated into randomized, prospective trials. Clinically equivalent treatments have shown differential effects or HRQOL: 9 mg daily of budesonide is superior to 15 mg, and hydrocortisone foam enemas are superior to prednisolone. Home parenteral nutrition has received modest support, limited again by study design. It is recommended that standard tests of HRQOL be used to increase comparability of studies and to increase the quality of this literature in general. In particular the Inflammatory Bowel Disease Questionnaire, Rating Form of Inflammatory Bowel Disease Concerns, and Direct Questioning of Objectives are recommended.

Intraoperative reasons for abandoning ileal pouch-anal anastomosis procedures

PURPOSE

Ileal pouch-anal anastomosis (IPAA) has become the operation of choice for most patients with chronic ulcerative colitis and familial adenomatous polyposis. However, because of technical or disease factors at the time of pouch construction, IPAA must sometimes be abandoned. A retrospective review was conducted to find reasons for IPAA failure or abandonment.

METHODS

Since 1981, 103 patients have had to have an IPAA procedure at the George Washington University Medical Center in Washington, DC. All charts were reviewed and data retrospectively collected.

RESULTS

Six of 103 patients (six percent) were unable to have IPAA constructed. Five patients ultimately received a standard end ileostomy, and one had an ileorectal anastomosis. The reasons for abandoning the IPAA procedure were an ischemic pouch, failure to reach the anus, poorly controlled presacral hemorrhage, desmoid of the mesentery, and finding incurable colon carcinoma.

CONCLUSIONS

Information regarding the risk of failure or abandonment during the IPAA procedure should be discussed with the patient during preoperative counseling and must be included as an element of informed consent.

Psychosocial adaptation to stoma surgery: a review

During the last decade strong improvements have been made in the medical care of patients with a digestive tract stoma, particularly with regard to nursing skills and to the quality of collecting material for faecal products. Scientific investigation into the psychosocial adjustment of patients after stoma surgery has intensified as well, giving us indications for quality of life. These developments induced a review of the actual state of affairs in psychological issues. After evaluating the results of psychosocial stoma research, it can be concluded that the technical improvements in stoma care during the past decade did not result in a decline in psychosocial problems after stoma surgery. However, there are some serious problems when interpreting the results of studies in this field of investigation. Stoma surgery is not per se solely responsible for the reported psychosocial problems, first, because many conclusions are based on research studies with poor design and, second, because these studies lack a theoretical framework within which the process of psychosocial adjustment has been measured and explained. This review assesses the most current developments and controversies in this field.

Recovery of anal sphincter function after the ileoanal reservoir procedure in patients over the age of fifty

PURPOSE

This study was undertaken to postoperatively assess the progression of anal sphincter function and clinical outcome in patients > or = 50 years old (Group I) compared with those < 50 years old (Group II).

METHODS

Clinical data were assessed after ileostomy closure by a questionnaire. These data were compiled to obtain an incontinence score, which ranged from 0 (perfect continence) to 20 (total incontinence). Anorectal manometry was performed preoperatively (MN1) and postoperatively, before (MN2) and after (MN3) ileostomy closure. Wilcoxon and paired t-test were used to compare the clinical and functional results, respectively.

RESULTS

Group I consisted of 22 patients (mean age, 56 years) and Group II, 50 patients (mean age, 32 years). No differences were found relative to either preoperative pressures or clinical outcome. However, both the mean and high resting pressures were significantly lower in Group I at the MN2 examination.

CONCLUSION

The effect on anal sphincters of ileoanal reservoir in patients over the age of 50 years is similar to that noted in younger patients. Transient impairment of internal anal sphincter function observed after ileoanal reservoir is more severe in older patients (P = 0.01). However, as in younger patients, it does completely recover after ileostomy closure.

Water-soluble contrast pouchography--technique and findings in 85 patients

A simple and safe technique for examining the ileal pouch in the post-operative period is described, and the findings in 85 patients reviewed. Extravasation from the ileo-anal anastomosis was seen in 10/85 (11%). In 14/85 (16%) the lateral view of the filled pouch showed a presacral space > 4 cm, which in 10 (71%) was due to a significant abnormality: six having an anastomotic leak with presacral abscess, two a large presacral haematoma, and two an abscess without anastomotic leak. Pouchography is recommended as a routine examination prior to closure of the covering ileostomy.

Restorative proctocolectomy and indeterminate colitis

One hundred seventy-five patients underwent restorative proctocolectomy between November 1984 and December 1992. The pathologic results were reviewed by two pathologists, one being a gastrointestinal pathologist. One hundred fifty-eight patients had a confirmed diagnosis of ulcerative colitis, and 16 patients were diagnosed with indeterminate colitis. In addition, one patient was diagnosed with familial adenomatous polyposis. Eight of the 158 patients with ulcerative colitis required removal of their pouches, and 3 of the 16 patients with indeterminate colitis required pouch removal. By this definition, the success rate for restorative proctocolectomy in patients with ulcerative colitis was 95% and the success rate for restorative proctocolectomy in patients with indeterminate colitis was 81%. Of the 16 patients with indeterminate colitis, 8 have satisfactory pouch function and 5 have some ongoing problems. We recommend this pathology-review approach to more clearly define which patients have indeterminate colitis and, therefore, to more accurately present to the patient the likelihood of success or failure of restorative proctocolectomy with this diagnosis.

Topical metronidazole treatment in pouchitis

Patients with pouchitis usually respond to oral metronidazole treatment, but side effects of the treatment are common. Eleven patients with pouchitis were given local treatment by instillation of metronidazole in doses of 40-160 mg daily into the reservoir. The effects of the treatment on the bacterial flora and short-chain fatty acids in reservoir contents, morphology of the ileal mucosa, and serum concentrations of metronidazole were studied. All patients responded to local administration of metronidazole. Three patients with chronic pouchitis remained well for 6 months, 3 years, and 4 years, taking 40 mg metronidazole daily. Three patients had one single treatment course, and four had repeated courses when they had recurrences. In one patient a continent reservoir had to be removed owing to a persistent ulcer causing chronic blood loss. The bacterial flora of reservoir contents showed no significant differences between patients with and without pouchitis. The number of anaerobic microorganisms and the concentration of short-chain fatty acids were reduced after metronidazole treatment. Serum concentrations of metronidazole were very low, and no patients experienced any side effects of the treatment. In conclusion, topical application of small doses of metronidazole relieved symptoms in most cases of pouchitis and was well tolerated, even as long-term treatment.

Ileal pouch-anal anastomosis: is preoperative anal manometry predictive of postoperative functional outcome?

PURPOSE

The aim of this study was to determine the value of preoperative anal manometry in predicting post-operative continence.

METHODS

Anal manometry was performed in 73 consecutive patients before ileal pouch-anal anastomosis (IPAA) surgery (m1), before loop ileostomy closure (m2), and at a follow-up of one (m3) and two (m4) years. Mean and maximum resting and squeezing pressures were documented at each occasion. One year after surgery, pressures were correlated (r) with an incontinence score.

RESULTS

A significant (P < 0.05) decrease in mean resting pressures was observed after IPAA (m1 = 66 mmHg; m2 = 42.8 mmHg), followed by a significant (P < 0.05) improvement of mean resting pressure after loop ileostomy closure (m3 = 53.8 mmHg; m4 = 54.7 mmHg). Mean squeezing pressures did not change (P > 0.05) at any time during the study (m1 = 114 mmHg; m2 = 102.9 mmHg; m3 = 103.4 mmHg; m4 = 95.8 mmHg). There was no correlation between preoperative mean resting pressure and postoperative (mI) incontinence score.

CONCLUSION

Anal manometry showed a characteristic trend in internal anal sphincter injury after IPAA followed by recovery after ileostomy closure. However, it failed to prove helpful in the prediction of clinical outcome. Thus, although this study supports the continued use of manometry in a research setting, it challenges the value of routine manometry in a clinical context.

Pelvic ileal reservoirs: the options

Restorative proctocolectomy has become an established surgical option for patients with chronic ulcerative colitis and familial adenomatous polyposis. However, despite a large number of different reservoir designs there is so far no acknowledged ideal configuration. This paper reviews the advantages and disadvantages of the different types of pelvic ileal reservoir so far studied.

Stapled ileoanal anastomosis without a temporary ileostomy

Stapled J-pouch ileoanal operations were performed in 75 patients (35 men, 40 women; 72 with ulcerative colitis, 3 with familial polyposis) without an ileostomy in 68 (43 taking prednisone, 12 emergent surgery, 8 completion proctectomy with ileostomy takedown). The seven primary ileostomies were due to technical difficulties in two patients and toxic colitis in four patients. No patients were lost to follow-up. Of patients followed for more than 1 month, 96% had perfect daytime control, 86% had no nocturnal accidents, and 73% had no nocturnal spotting. Mucosa between the dentate line and the anastomosis averaged 1.1 +/- 1.0 cm, with the anastomosis at, or below, the dentate line in 16 patients, of whom 14 had excellent continence. Stools in 24 hours averaged 6.9 +/- 0.3, of which 1.8 +/- 0.2 were at night. Stool frequency was unrelated to gender, anastomotic distance from the dentate line, or age; however, patients 50 years of age or older had more problems with nocturnal fecal control than those younger than 50 years of age. Anastomotic leaks (four), cuff abscess (one), pouch leaks (two), and pelvic abscesses (three) were treated with drainage in all patients and ileostomy in five. Pouchitis occurred in 31% of patients and responded to oral antibiotic therapy. Acute complications were fewer, functional pouches greater, stool control better, and overall hospitalization shorter (all p < 0.01) than those in our 63 patients with a mucosectomy and handsewn ileoanal anastomosis.

Obstruction after ileal pouch-anal anastomosis: a preventable complication?

Small bowel obstruction is a common complication after ileal pouch-anal anastomosis. This review of 460 patients examines the frequency of small bowel obstruction and determines potential risk factors. The leading indication for ileal pouch-anal anastomosis was ulcerative colitis (83 percent). In 142 patients (31 percent), loop ileostomy was rotated 180 degrees to facilitate emptying of the ileostomy. Ninety-four patients (20 percent) had 109 episodes of obstruction. Obstruction occurred after creation of the pouch (40 episodes), closure of the ileostomy (29 episodes), or developed during the subsequent follow-up period (40 episodes). Operative intervention was required in 39 percent of the episodes (7 percent of all patients). At operation, the most common point of obstruction was at closure of the ileostomy (n = 22/42, 52 percent). In 16 of these patients, the ileostomy had been rotated. Multiple risk factors, including age, sex, primary diagnosis, surgeon incidence, pouch type, prior colectomy, steroid usage, stomal rotation, technique of closure of the ileostomy, and prior obstruction, were examined by univariate and multivariate analysis. Of all factors, only stomal rotation was statistically significant (P = 0.0005, chi-squared analysis). Rotation of the loop ileostomy during ileal pouch-anal anastomosis, although an apparent technical refinement, is unnecessary and predisposes to obstruction.

Quality of life after restorative proctocolectomy with a pelvic ileal reservoir compares favorably with that of patients with medically treated colitis

There remains some reluctance among physicians to refer patients for restorative proctocolectomy (RP). They argue that their patients would be worse off with a pouch because of the attendant problems of urgency and frequent bowel actions. The aim of this study was to compare quality of life in patients who had undergone RP with that of patients with ulcerative colitis on long-term medical treatment. A detailed questionnaire and the Hospital Anxiety and Depression (HAD) test were completed by 103 patients who had undergone RP and by 95 patients with ulcerative colitis on medical treatment and in remission attending a gastroenterology clinic. Patients with a pouch had a greater frequency of bowel action [five times per 24 hours (range, 4-7) vs. two times per 24 hours (range, 1-3); P < 0.001] but less urgency of defecation [12/103 (11.7 percent) vs. 69/95 (72.6 percent); P < 0.001] than patients with medically treated colitis. Efficiency of evacuation, discrimination between flatus and feces, use of perianal pads, and perianal soreness were similar. Use of antidiarrheal medication was more common in the pouch group [53 of 103 patients (51.5 percent) vs. 3 of 95 patients (3.2 percent); P < 0.05], whereas use of topical steroids was more common in medically treated patients [40 of 95 patients (47.1 percent) vs. 9 of 103 patients (8.7 percent); P < 0.05]. Limitation of social activity and HAD scores were significantly higher in medically treated patients. Quality of life for patients with a pouch appears to be as good as that for patients with medically treated colitis.

Quality of life after total proctocolectomy and ileal J-pouch-anal anastomosis

We investigated the daily life and opinions of patients after total proctocolectomy and ileal J-pouch-anal anastomosis. Eighty patients answered a questionnaire, completed Cattell's anxiety scale, and recorded bowel function for one month. Both colitis and polyposis patients defecated five times daily, had 1.6 episodes of nocturnal motions weekly, and soiled twice weekly. However, colitis patients were more satisfied with their bowel function and surgical outcome than were polyposis patients. This difference had a close relationship to the personality factors of ego strength and frustration. All patients with either disease who defecated less than three times daily, had no nocturnal motions, and had no soiling showed normal ego strength and frustration and were completely satisfied with their bowel status and operation. In contrast, patients defecating more than seven times daily or more than once per week nocturnally and soiling more than four times weekly had high frustration and were dissatisfied. Thus, satisfaction with surgery correlated not only with the objective outcome but also with personality and lifestyle.

Consequences of delayed ileostomy closure after ileal pouch-anal anastomosis

Temporary diverting loop ileostomy is a generally accepted component of the ileal pouch-anal anastomosis (IPAA) procedure. Ileostomy closure is usually performed within two to three months but may be delayed because of disruption of the ileonanal anastomosis, suspected leak from the ileal reservoir, concomitant medical problems, or patient convenience. Of 362 patients undergoing IPAA at The Cleveland Clinic Foundation for inflammatory bowel disease, 10 have had their ileostomy closures delayed for more than six months. Clinical and manometric parameters are examined in these patients and compared with those who had earlier closure. There appears to be no significant difference in the functional outcome of IPAA in these patients in terms of number of bowel movements and degree of continence. Reservoir compliance and maximum tolerated volumes are similar. We conclude that delaying ileostomy closure for more than six months after IPAA has no deleterious effect on pouch function.

The failing pelvic pouch conversion to continent ileostomy

Excision of a failing pelvic pouch is often a great disappointment for the patient. It is also an unfortunate decision considering that a significant length of terminal ileum is sacrificed. Transformation of the pouch to a continent ileostomy is an alternative. Five patients with a malfunctioning pelvic pouch have had their pouch converted to a continent ileostomy. The operative technique is described.

Management of familial adenomatous polyposis

The management of FAP involves treatment of affected individuals and their families. Such an approach is best coordinated by registrars working in dedicated registries, in close collaboration with nurses, physicians, surgeons, clinical geneticists and others who become involved in the care of these patients. The large bowel of patients with FAP should be removed (totally or subtotally) by the third decade of life. Screening of other areas at risk is recommended to document the natural history of extracolonic manifestations and to allow study of the effects of intervention. Despite these other, sometimes life-threatening manifestations, a near to normal life span is possible in the majority of patients with FAP. The aims of management of the individual and of the family are to ensure that their quality of life is optimal, that support is provided in times of emotional need, that anxiety is minimized and that relatives are adequately screened and treated.

Colectomy-proctomucosectomy with S-pouch: operative procedures, complications, and functional outcome in 69 consecutive patients

Sixty-nine patients were operated upon in a three-stage procedure. Early complications occurred in 29 percent after colectomy-ileostomy, in 25 percent after proctomucosectomy with ileoanal anastomosis and loop ileostomy, and in 9 percent after closure of loop ileostomy. Only three of these were considered serious. Seventy-one percent of the patients were readmitted into the hospital between the three operations or after the last one. Total hospital stay was 49 days (median); the range was 20 to 345 days. Reconstruction of the reservoir was performed in four patients owing to defecation problems, with satisfying functional results in two patients, while two emptied by catheter. There was no postoperative mortality or pelvic sepsis, and no pouches were excised. Ileostomy was re-established in two patients. At histopathologic re-evaluation of colectomy specimens, the diagnosis was changed from ulcerative colitis to Crohn's disease in three patients and to indeterminate colitis in five. Median follow-up was 4.3 years. Continent anal defecation without ileostomy was achieved in 67 patients (97 percent), with 4.1 bowel movements per day and 0.6 per night. Perfect continence was achieved in 55 percent in the daytime and in 43 percent at night. The low rate of reservoir-threatening complications is attributed to the three-stage procedure and the technical details in the surgical procedures.

Ileal pouch-anal anastomosis without ileostomy

Thirty-seven patients underwent construction of a J-ileal pouch-anal anastomosis (IPAA) without temporary diverting ileostomy for chronic ulcerative colitis (CUC) (20 patients), familial adenomatous polyposis (FAP) (15 patients), indeterminate colitis (1 patient) and nonhereditary polyposis coli (1 patient) between 1981 and 1990. Seven of 20 CUC patients (35 percent) were on steroids at the time of hospital admission. The postoperative course of these patients was compared with that of a group of patients undergoing IPAA with ileostomy during that same time period and matched for age, sex, diagnosis, date of surgery, and steroid use. Eight patients (22 percent) in the group without ileostomy and four patients (11 percent) with ileostomy experienced one or more postoperative pouch-related complications. Complications requiring reoperation in patients without ileostomy occurred more frequently in patients either taking steroids or having previous pelvic radiation therapy. Functional results in patients undergoing one-stage procedures after a mean of 28 postoperative months were comparable to those in patients having staged procedures. Surgeons' criteria for a one-stage procedure in these patients should include absolute lack of tension on the anastomosis, good blood supply to the terminal ileum, good general health, and absence of recent intake of steroids at the time of surgery. We conclude that J-pouch construction with IPAA can be safely performed without diverting ileostomy, provided that these selection factors are taken into account.

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.

Consequences of ileal pouch-anal anastomosis for Crohn's colitis

Patients with Crohn's colitis are generally not considered candidates for the ileal pouch-anal anastomosis (IPAA) procedure. We reviewed 362 consecutive patients undergoing IPAA and analyzed the outcome of this procedure on 25 patients with a preoperative diagnosis of mucosal ulcerative colitis who were subsequently proven to have Crohn's disease. The mean follow-up was 38.1 months. Sixteen patients have a functioning pouch, seven have required pouch excision, one is diverted, and one has died. Only one of nine patients in whom there was a preoperative clinical feature suggestive of Crohn's disease has a functioning pouch, with complications uniformly occurring within months of ileostomy closure. In contrast, 15 of 16 patients without preoperative features of Crohn's disease have maintained their pouch, generally with good results. These data suggest that patients in whom there is clinical and pathologic evidence of Crohn's disease do very poorly without meaningful symptom-free intervals. However, patients without any clinical features of Crohn's disease, despite a histopathologic diagnosis of Crohn's colitis, have had a good outcome with IPAA thus far.
