One-stage restorative proctocolectomy without temporary ileostomy for ulcerative colitis: a note of caution

Routine diversion following delayed IPAA construction does not reduce the incidence of pouch-related sepsis or failure in patients with ulcerative colitis

AIM

The aim of this study was to compare modified 2-stage and 3-stage IPAA construction techniques to evaluate the effect of diverting loop ileostomy following completion proctectomy and IPAA for ulcerative colitis. In addition, our overall institutional experience was reviewed to describe long-term outcomes and changes in staging trends over time.

METHODS

Our institutional database was searched to identify all cases of IPAA for ulcerative colitis between 1981 and 2018. Patient, pouch and outcome characteristics were abstracted. Primary study outcomes were the incidence of primary pouch failure and pouch-related sepsis. Failure was evaluated by Kaplan-Meier estimates of survival over time. The adjusted effect of pouch stage was evaluated using multivariable Cox and logistic regression models. Exploratory analysis evaluated the effect of stage on failure in the pouch related sepsis subgroup.

RESULTS

A total of 2105 patients underwent primary IPAA over the study period. The 5, 10 and 20-year pouch survival probabilities were 95.2%, 92.7% and 86.6%. The incidence of pouch related sepsis was 12.3%. Adjusted analysis demonstrated no difference in pouch failure (HR = 0.64: 95% 0.39-1.07, p = 0.09) or post-operative sepsis (aOR = 0.79: 95% CI 0.53-1.17, p = 0.24) by stage of construction. Among patients experiencing pouch sepsis, there was no difference in Kaplan-Meier estimates of pouch survival by stage (p = 0.90).

CONCLUSIONS

Pouch related sepsis and IPAA failure did not differ between modified 2-stage and 3-stage construction techniques. Among the sub-group of patients experiencing pouch related sepsis, there was no difference in failure between groups. The results suggest diverting ileostomy may be safely avoided following delayed pouch reconstruction in appropriately selected patients.

Staged Approaches to Restorative Proctocolectomy with Ileoanal Pouch-When and Why?

Restorative proctocolectomy (RPC) with ileal pouch anal-anastomosis (IPAA) is commonly performed for patients with ulcerative colitis, familial adenomatous polyposis, and selected phenotypes of Crohn's disease (CD). Due to concerns about the effects of surgical complications on pouch functional outcomes, debate remains surrounding when and whether RPC with IPAA should be performed in a staged manner. Particularly debated are the timings of the IPAA, whether it is constructed at time of the proctocolectomy and whether to utilize temporary fecal diversion with a loop ileostomy. RPC with IPAA can be performed in one, two, or three stages, with each stage typically separated by 3-6 months. Proponents of a staged approach argue that poor pouch function, which is often a result of IPAA complications, including leak and infection, can be difficult to overcome and mandate additional, major surgeries, and that staging pouch creation and pairing with a protective ileostomy reduce those complications. However, subjecting patients to multiple surgeries and prolonging their time with an ileostomy present unique risks as well. Surgeons' experience and preference and patient characteristics need to be considered when determining operative planning. Highly selected patients with CD can be considered for RPC with IPAA, although with an acknowledgment of inherently higher pouch failure rates. Understanding the short- and long-term consequences of RPC with IPAA construction can help surgeons determine the appropriate approach.

Is diversion free ileal pouch-anal anastomosis a safe procedure? A meta-analysis of 4973 cases

PURPOSE

Ileal pouch-anal anastomosis (IPAA) has been established as the procedure of choice for patients who require excision of the colon and rectum for familial adenomatous polyposis and ulcerative colitis. The requirement for proximal stomal diversion in IPAA is controversial.

OBJECTIVES

To compare post-operative outcomes following IPAA with and without proximal diversion.

METHODS

Computerised literature search, of Ovid MEDLINE and EMBASE. Full-text comparative studies published between 1992 and 2019, in English language and on adult patients. Ileal pouch-anal anastomosis with or without proximal stomal diversion following proctocolectomy. Outcome measures were anastomotic leak, anastomosis strictures, re-operations, pouch failure, intra-abdominal sepsis, small bowel obstruction/ileus and mortality.

RESULTS

Five hundred and forty-six studies were screened. Fourteen relevant studies included 4973 cases (1832 patients with no stomas vs 3141 with stomas). Anastomotic strictures (p ≤ 0.0001 OR 0.40; 95% CI (0.26-0.62)) and pouch failures (p = 0.003 OR 0.54; 95% CI (0.36-0.82)) were higher in diverted than non-diverted patients. Re-operation was more frequently required in non-diverted patients (p = 0.02 OR 2.51; 95% CI (1.12-5.59)). Heterogeneity was low in 5 out of 7 variables.

CONCLUSION

In selected patients, diversion-free IPAA is a safe procedure associated with lower anastomotic stricture and pouch failure rates than diverted IPAA. This appears to occur at the expense of a higher re-operation rate. An RCT is required to help define the selection criteria.

Current trends regarding protective ileostomy after restorative proctocolectomy

The decision to perform a protective ileostomy after ileoanal-pouch anastomosis is con- troversial, and most of the discussion is based on its advantages and disadvantages. Al- though a temporary intestinal diversion has been routinely indicated in most patients, this choice is also associated with complications. The present work aims to review the outcomes after restorative proctocolectomy with or without a protective ileostomy in the treatment of ulcerative colitis and polyposis syndromes. Most papers emphasize that di- version protects against anastomosis leaks; consequently, it may prevent pelvic sepsis and pouch failure. Otherwise, a defunctioning ileostomy may cause morbidity such as dehydra- tion, electrolyte imbalance, psychological problems, skin irritation, anastomosis strictures and intestinal obstruction, among others. There are those who believe that the omission of an ileostomy after the confection of ileal pouches should be reserved for selected patients, with quite acceptable results. The selection criteria should include surgeon, patient and procedure features to ensure a good outcome.

Fecal continence outcomes are associated with the type, height, and stage procedure of ileal pouch-anal anastomosis

PURPOSE

This study aims to analyze the quality of life in patients with an ileal pouch-anal anastomosis (IPAA) and to investigate the association between height and type of the anastomosis, the number of stage procedures and age, and the fecal continence outcomes.

METHODS

This is a cross-sectional retrospective study in patients who had undergone IPAA between 1992 and 2016 (N = 133). We sent questionnaires to 102 eligible patients (64% response rate). We used the Wexner score to assess fecal incontinence: 0 = no incontinence to 20 = complete incontinence. We used RAND-36 to measure quality of life.

RESULTS

Patients who underwent mucosectomy with hand-sewn anastomoses (n = 11, 17%) had significantly higher median Wexner scores than patients with stapled anastomoses (10 versus 3, P = 0.003). Lower anastomoses correlated significantly with increasing Wexner scores (r = - 0.468, P < 0.001). Quality of life of incontinent patients was diminished. Patients who were older at the time of IPAA surgery had higher Wexner scores (P = 0.004), while the time between surgery and questionnaire did not influence their Wexner scores (P = 0.810). Considering the stage procedures, multiple linear regression showed that the two-stage procedure without diverting ileostomy was significantly associated with higher Wexner scores (B = 0.815, P = 0.02), adjusted for sex (P = 0.008) and anastomosis type (P = 0.002). The three-stage procedure showed equally low complications and anastomotic leakage rates.

CONCLUSION

Mucosectomy with more distal, hand-sewn anastomosis and increasing age at IPAA surgery was associated with poorer fecal continence outcomes. The three-stage procedure appears to give the best fecal continence results without increasing complications. Furthermore, incontinence reduced patient's quality of life.

Morbidity related to diverting ileostomy after restorative proctocolectomy in patients with ulcerative colitis

AIM

Restorative proctocolectomy with ileal pouch-anal anastomosis is considered by many surgeons to be the standard procedure for surgical management of ulcerative colitis. There is controversy about whether or not a covering ileostomy should be constructed. The aim of this study was to evaluate the outcomes and morbidity for patients with ulcerative colitis who underwent restorative proctocolectomy with or without a diverting ileostomy.

METHOD

This is a retrospective study of a consecutive series of 510 patients with ulcerative colitis who were operated on in Helsinki University Hospital between January 2005 and June 2016. A diverting ileostomy was performed in 119 patients (the stoma group) compared with 391 patients with no stoma.

RESULTS

Dehydration and intestinal obstruction occurred more often in the stoma group (P < 0.0001). Clinical anastomotic leakage was more common among patients without an ileostomy (6.6% vs 1.7%, P = 0.04). However, the need for re-laparotomy because of any early complication did not differ between the groups (P = 0.58). Within 3 months, 50 patients with ileostomy (42.0%) and 51 patients without (13.0%) were readmitted (P < 0.0001). In total, 35 patients (29.3%) had a complication relating to ileostomy closure and four of them required surgery. There was no difference in the rate of fistulas, pouchitis or pouch failure between the groups.

CONCLUSION

Our study shows that a diverting ileostomy is associated with considerable morbidity but it does not seem to prevent later failure of the pouch. We suggest that a diverting ileostomy should only be constructed for high-risk patients.

Diverted versus undiverted restorative proctocolectomy for chronic ulcerative colitis: an analysis of long-term outcomes after pouch leak short title: outcomes after pouch leak

BACKGROUND

The safety of undiverted restorative proctocolectomy (RPC) is debated. This study compares long-term outcomes after pouch leak in diverted and undiverted RPC patients.

METHODS

Data were obtained from a prospectively maintained registry from a single surgical practice. One-stage and staged procedures with an undiverted pouch were considered undiverted pouches; all others were considered diverted pouches. The outcomes measured were pouch excision and long-term diversion defined as the need for loop ileostomy at 200 weeks after pouch creation. Regression models were used to compare outcomes.

RESULTS

There were 317 diverted and 670 undiverted pouches, of which 378 were one-stage procedures. Pouch leaks occurred in 135 patients, 92 (13.7%) after undiverted, and 43 (13.6%) after diverted pouches. Eighty-six (64%) leaks were diagnosed within 6 months of pouch creation. Undiverted patients underwent more emergent procedures within 30 days of pouch creation (p < 0.01). Pouch excision occurred in 14 (33%) diverted patients and 13 (14%) undiverted patients (p = 0.01). Thirteen (32%) diverted patients and 18 (21%) undiverted patients (p = 0.17) had ileostomies at 200 weeks after surgery. In multivariable analyses, diverted patients had a higher risk of pouch excision (HR 3.67 p < 0.01), but similar rates of ileostomy at 200 weeks (HR 1.8, p = 0.19) compared to undiverted patients.

CONCLUSIONS

Despite a likely selection bias in which "healthier" patients undergo an undiverted pouch, our data suggest that diversion does not prevent pouch excision and the need for long-term diversion after pouch leak. These findings suggest that undiverted RPC is a safe procedure in appropriately selected patients.

Outcome of restorative proctocolectomy with an ileo-anal pouch for ulcerative colitis: effect of changes in clinical practice

AIM

Surgery for ileal pouch-anal anastomosis (IPAA) has evolved over time, especially since the introduction of laparoscopy. The aim of this retrospective study was to report the impact of surgical evolution on outcome over a period of 25 years.

METHOD

All patients who had IPAA surgery for ulcerative colitis from 1990 to 2015 at the University Hospitals of Leuven were included. Patients were divided into three period arms (period A 1990-1999; period B 2000-2009; period C 2010-2015). The main outcome measure was anastomotic leakage.

RESULTS

A total of 335 patients (58.8% male) with a median age of 39 years (interquartile range 32-49 years) at surgery were included. Median follow-up was 5 years (interquartile range 2-10 years). Overall anastomotic leakage (grades A-C) was 14.9%. A significant decrease in leakage rate was observed over time (from 21.4% in period A to 12.1% in period B to 10.0% in period C; P = 0.04). The defunctioning ileostomy rate at the time of pouch construction decreased from 91.7% (period A) to 40.3% (period B) to 11.1% (period C) (P < 0.001). We observed an increase in the use of laparoscopy (23.9% in period A vs 72.6% in period B, vs 84.4% in period C; P = 0.001) and a shift to a modified two-stage procedure (4.1% in period A, vs 66.7% in period C; P < 0.0001). In a monocentric study with some of the data retrieved retrospectively it was not possible to account for the impact of preoperative nutritional status (weight loss, serum albumin level) or disease burden. Other outcome factors were not measured, for example sexual function and fecundity.

CONCLUSION

A higher rate of laparoscopic IPAA surgery, together with a shift towards modified two-stage procedures, was associated with a lower leakage rate despite a reduction in the use of defunctioning ileostomy.

Management of ulcerative colitis in Taiwan: consensus guideline of the Taiwan Society of Inflammatory Bowel Disease

Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic mucosal inflammation of the colon, and the prevalence and incidence of UC have been steadily increasing in Taiwan. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of UC taking into account currently available evidence and the expert opinion of the committee. Accurate diagnosis of UC requires thorough clinical, endoscopic, and histological assessment and careful exclusion of differential diagnoses, particularly infectious colitis. The goals of UC therapy are to induce and maintain remission, reduce the risk of complications, and improve quality of life. As outlined in the recommended treatment algorithm, choice of treatment is dictated by severity, extent, and course of disease. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to immunosuppressive treatment, especially with steroids and biologic agents, and should be regularly monitored for reactivation of latent infection. These consensus statements are also based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of UC in Taiwan.

The Role of Temporary Fecal Diversion

The use of temporary fecal diversion is of great importance to tenuous anastomosis, immunosuppressed patient, or actively infected patient. Its use protects newly constructed intestinal anastomoses from being the culprit of pelvic sepsis or systemic illness. Thus, potential morbidity and mortality can be averted. However, its appropriate or optimal use is often debated. We herein discuss the evidence for when to best use a diverting stoma for colorectal, coloanal, and ileoanal anastomoses. We also discuss the importance of considering a temporary diverting stoma in the setting of high-dose immunosuppression (e.g., transplant patients or inflammatory bowel disease), active infection, or upon creation of ileal pouch-anal anastomosis. Lastly, we discuss the advantages and disadvantages of a loop ileostomy versus colostomy for temporary diversion of fecal contents.

Clinical Aspects of Idiopathic Inflammatory Bowel Disease: A Review for Pathologists

CONTEXT

-Idiopathic inflammatory bowel disease manifests with different clinical phenotypes showing varying behavior and risk for neoplasia. The clinical questions that are posed to pathologists differ depending on phase of the disease and the clinical circumstances. Understanding the clinical aspects of the dynamic disease process will enhance the role of pathology in optimizing the care of patients with inflammatory bowel disease.

OBJECTIVE

-To review clinical and surgical aspects of inflammatory bowel disease that are relevant to practicing pathologists.

DATA SOURCES

-The literature was reviewed.

CONCLUSIONS

-Diagnosis and management of inflammatory bowel disease require an integrated evaluation of clinical, endoscopic, radiologic, and pathologic features. Therefore, close interaction between clinicians and pathologists is crucial. Having this team approach improves understanding of the pertinent clinical and surgical aspects of the disease and assists in the recognition of unusual presentation of variants, as well as mimics of idiopathic inflammatory bowel disease, by pathologists.

Second Korean guidelines for the management of ulcerative colitis

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by a relapsing and remitting course. The direct and indirect costs of the treatment of UC are high, and the quality of life of patients is reduced, especially during exacerbation of the disease. The incidence and prevalence of UC in Korea are still lower than those of Western countries, but have been rapidly increasing during the past decades. Various medical and surgical therapies, including biologics, are currently used for the management of UC. However, many challenging issues exist, which sometimes lead to differences in practice between clinicians. Therefore, the IBD study group of the Korean Association for the Study of Intestinal Diseases established the first Korean guidelines for the management of UC in 2012. This is an update of the first guidelines. It was generally made by the adaptation of several foreign guidelines as was the first edition, and encompasses treatment of active colitis, maintenance of remission, and indication of surgery for UC. The specific recommendations are presented with the quality of evidence and classification of recommendations.

Restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis: A narrative review

Restorative proctocolectomy with ileal pouch-anal anastomosis (RP-IPAA) is the gold standard surgical treatment for ulcerative colitis. However, despite the widespread use of RP-IPAA, many aspects of this treatment still remain controversial, such as the approach (open or laparoscopic), number of stages in the surgery, type of pouch, and construction type (hand-sewn or stapled ileal pouch-anal anastomosis). The present narrative review aims to discuss current evidence on the short-, mid-, and long-term results of each of these technical alternatives as well as their benefits and disadvantages. A review of the MEDLINE, EMBASE, and Ovid databases was performed to identify studies published through March 2016. Few large, randomized, controlled studies have been conducted, which limits the conclusions that can be drawn regarding controversial issues. The available data from retrospective studies suggest that laparoscopic surgery has no clear advantages compared with open surgery and that one-stage RP-IPAA may be indicated in selected cases. Regarding 2- and 3-stage RP-IPAA, patients who underwent these surgeries differed significantly with respect to clinical and laboratory variables, making any comparisons extremely difficult. The long-term results regarding the pouch type show that the W- and J-reservoirs do not differ significantly, although the J pouch is generally preferred by surgeons. Hand-sewn and stapled ileal pouch-anal anastomoses have their own advantages, and there is no clear benefit of one technique over the other.

Defunctioning Ileostomy is not Associated with Reduced Leakage in Proctocolectomy and Ileal Pouch Anastomosis Surgeries for IBD

BACKGROUND

Anastomotic leakage is a serious complication after restorative proctocolectomy with ileal pouch-anal anastomosis. Previous studies have shown significantly decreased leak rates in diverted patients with less severe clinical consequences. The aim of this study was to evaluate short- and long-term outcome of selective ileostomy formation in a multicentre cohort of patients undergoing pouch surgery.

METHODS

In a retrospective study, 621 patients undergoing pouch surgery for inflammatory bowel disease [IBD] were identified from three large centres. Anastomotic leakage was defined as any leak confirmed by either contrast extravasation on imaging or during surgical re-intervention.

RESULTS

In 305 patients [49.1%], primary defunctioning ileostomy was created during pouch surgery and 41 [6.6%] patients received a secondary ileostomy because of a leaking non-diverted pouch. Primary ileostomy formation was associated with male sex, weight loss, American Society of Anesthesiologists score [ASA] > 2, steroid use, one-stage surgery, hand-sewn anastomosis, and blood transfusion. Leak rates were comparable between diverted and non-diverted patients [16.7% vs 17.1%, p = 0.92], which remained unchanged in subgroups with immunosuppressive medication. Having had an ileostomy was demonstrated to be an independent predictor of small bowel obstruction (odds ratio [OR] 2.58, 95% confidence interval [CI] 1.45 - 4.67) and pouch fistulas [OR 3.05, 95%CI 1.06 - 8.73]. The 10-year pouch survival was comparable for patients with and without ileostomy [89% versus 88%, p = 0.718].

CONCLUSIONS

Leakage rates of diverted and non-diverted pouches in IBD patients were similar and relatively high. Defunctioning was independently associated with long-term complications. A staged approach without defunctioning might be the best strategy.

Early and late surgical outcomes of ileal pouch-anal anastomosis within a defined population in Sweden

OBJECTIVE

Ileal pouch-anal anastomosis (IPAA), has become the procedure of choice in patients requiring reconstructive surgery for ulcerative colitis or familial adenomatous polyposis. The aim of this population-based study was to present data prospectively registered and retrospectively evaluated on the short-term and the long-term results of 124 consecutive IPAA performed chronologically by three surgeons in a single referral centre.

MATERIALS AND METHODS

All patients who underwent IPAA from 1993 to 2012 were included. Early and late morbidity and mortality were evaluated.

RESULTS

Early complications were observed in 25 patients. There was one death from cardiac failure, high output stoma occurred in six patients and wound infection occurred in four patients. Complications were associated with higher BMI (P=0.032). Four patients had to be reoperated. Peroperative bleeding was reduced when using an ultrasonically activated scalpel for the perimuscular dissection (P<0.00001). Clavien-Dindo grade III-V affected five patients. Only one patient developed anastomotic leak and septic complications.Late complications occurred in 61 patients. There was no procedure-related mortality. Pouchitis was the most common complication (n=37). Primary sclerosing cholangitis and age younger than 40 years were associated significantly with a three- and two-fold increased risk of pouchitis, respectively. Small bowel obstruction was the second most common complication (n=16), more common in women (P=0.031). The pouch failure rate was low: 2.4%. Clavien-Dindo grade III-V affected 13 patients.

CONCLUSION

In the hands of experienced high-volume surgeons, IPAA is a safe procedure associated with a relatively low early morbidity as well as an acceptable late morbidity.

Ileo-anal pouch excision: A review of indications and outcomes

Restorative proctocolectomy (RP) is the surgical treatment of choice for ulcerative colitis (UC) and patients with familial adenomatous polyposis (FAP). A devastating complication for both patient and surgeon is failure of the pouch that requires excision. There is currently no single paper in the literature that consolidates the indications for ileo-anal pouch excision and the subsequent outcomes following this procedure. A literature search was carried out to identify articles on RP and ileal pouch-anal anastomosis. The main search terms used were “RP”; “ileal pouch-anal anastomosis” or “ileal reservoir” or “ileal pouch”; “failure of ileal pouch-anal anastomosis” and “excision of ileal pouch-anal anastomosis”. The search was completed using electronic databases MEDLINE, PubMed and EMBASE from 1975 to June 2014. Characteristics of patients with pouch failure differ between institutions. Reported overall excision rates of the pouches vary and in this review ranged from 0.93% to 12.8%. Age and lower institutional volume (less than 3.3 cases) were independent predictors of pouch failure; however surgeon case load was not. The main reasons identified for excision are sepsis (early cause), Crohn’s disease and poor functional outcomes (both late causes). Pouch cancers in UC and FAP are still rare but 135 cases exist in the literature. The most common complication following excision is persistent perineal sinus. The decision to excise a pouch should not be taken lightly and an awareness of the technical pitfalls and complications that can occur should be fully appreciated.

Characterizing readmission in ulcerative colitis patients undergoing restorative proctocolectomy

BACKGROUND

Postoperative readmissions increase costs and affect patient quality of life. Ulcerative colitis (UC) patients are at a high risk for hospital readmission following restorative proctocolectomy (RP).

OBJECTIVE

The objective of this study is to characterize UC patients undergoing RP and identify causes and risk factors for readmission.

DESIGN

A retrospective review of a prospectively maintained institutional database was performed. Postoperative readmission rates and reasons for readmission were examined following RP. Univariate and multivariate analyses were performed to evaluate for risk factors associated with readmission.

RESULTS

Of 533 patients who met our inclusion criteria, 18.2 % (n = 97) were readmitted within 30 days while 22.7 % (n = 121) were readmitted within 90 days of stage I of RP. Younger patient age (OR 1.825, 95 % CI 1.139-2.957), laparoscopic approach (OR 1.943, 95 % CI 1.217-3.104), and increased length of initial stay (OR 1.155, 95 % CI 1.090-1.225) were all associated with 30-day readmission. The most common reason for readmission was dehydration/ileus/partial bowel obstruction, with 10 % of patients readmitted for this reason within 30 days.

CONCLUSIONS

Patients undergoing restorative proctocolectomy are at high risk for readmission, particularly following the first stage of the operation. Novel treatment pathways to prevent ileus and dehydration as an outpatient may decrease the rates of readmission following RP.

Initial surgical management of ulcerative colitis in the biologic era

BACKGROUND

The initial minimum operation for ulcerative colitis is a total abdominal colectomy. Healthy patients may undergo proctectomy at the same time; however, for ill patients, proctectomy is delayed. Since the introduction of biologic medications in 2005, ulcerative colitis medical management has changed dramatically.

OBJECTIVE

We examined how operative management for ulcerative colitis has changed from the prebiologic to biologic eras.

DESIGN

We conducted a retrospective review of data on patients with ulcerative colitis who were included in the Nationwide Inpatient Sample database.

SETTINGS

This study was conducted at a single university.

PATIENTS

A total of 1,547,852 patients with ulcerative colitis who were admitted to a US hospital from 1991 to 2011 were included in the study.

MAIN OUTCOME MEASURES

We examined patients whose initial operation consisted of total abdominal colectomy without proctectomy versus a total proctocolectomy with or without a pouch. We also examined which operation was done at the time of the construction of an ileoanal pouch. Patients who underwent colectomy and pouch construction in the same hospitalization were compared with those who received pouch formation at a subsequent hospitalization.

RESULTS

Ulcerative colitis-related admissions rose by 170% during the years examined, and the number of patients who required total abdominal colectomy increased by 44%. Total abdominal colectomy increased by 15%, as opposed to total proctocolectomy (p < 0.001). Pouch construction at a subsequent operation increased by 16% (p = 0.002). Since 2008, total abdominal colectomy has surpassed total proctocolectomy as the most common initial surgical intervention for ulcerative colitis.

LIMITATIONS

The Nationwide Inpatient Sample is a retrospective database, and we were limited to examining the variables within it.

CONCLUSIONS

Total abdominal colectomy is currently the most common initial operation for patients with ulcerative colitis, and an ileoanal pouch is more frequently constructed at a subsequent hospitalization. These trends coincide with the initiation of biologic treatments and may imply that patients are acutely ill at the time of initial operation. Alternately, there may be surgeon-perceived bias of increased surgical risk or a shift in care to specialized surgeons for pouch construction.

Morbidity of loop ileostomy closure after restorative proctocolectomy for ulcerative colitis and familial adenomatous polyposis: a systematic review

BACKGROUND

Temporary loop ileostomy is a routine procedure to reduce the morbidity of restorative proctocolectomy. However, morbidity of ileostomy closure could reduce the benefit of this concept. The objective of this systematic review was to assess the risks of ileostomy closure after restorative proctocolectomy for ulcerative colitis or familial adenomatous polyposis.

MATERIALS AND METHODS

Publications in English or German language reporting morbidity of ileostomy closure after restorative proctocolectomy were identified by Medline search. Two hundred thirty-two publications were screened, 143 were assessed in full-text, and finally 26 studies (reporting 2146 ileostomy closures) fulfilled the eligibility criteria. Weighted means for overall morbidity and mortality of ileostomy closure, rate of redo operations, anastomotic dehiscence, bowel obstruction, wound infection, and late complications were calculated.

RESULTS

Overall morbidity of ileostomy closure was 16.5 %, there was no mortality. Redo operations for complications were necessary in 3.0 %. Anastomotic dehiscence occurred in 2.0 %. Postoperative bowel obstruction developed in 7.6 %, with 2.9 % of patients requiring laparotomy for this complication. Wound infection rate was 4.0 %. Hernia or bowel obstruction as late complications developed in 1.9 and 9.4 %, respectively.

CONCLUSION

The considerable morbidity of ileostomy reversal reduces the overall benefit of temporary fecal diversion. However, ileostomy creation is still recommended, as it effectively reduces the risk of pouch-related septic complications.

Outcomes and cost of diverted versus undiverted restorative proctocolectomy

BACKGROUND

Some observational studies suggest that diversion during restorative proctocolectomy mitigates the risk of anastomotic complications. However, diversion has its own costs and complications. The aim of this study was to compare the cost and outcomes of diverted to undiverted restorative proctocolectomy.

METHODS

This study took advantage of a natural experiment within one surgical department to understand the clinical and financial implications of diversion during restorative proctocolectomy. For the last 10 years, two surgeons routinely diverted all patients undergoing restorative proctocolectomy, and two other surgeons routinely did not. The medical records of 288 consecutive restorative proctocolectomy patients were reviewed. Minimum follow-up time was 1 year, with an average of 4.7 years. Complications rates and costs of care were collected.

RESULTS

There were no significant differences between rates of anastomotic leak, fistula, or hernias in diverted versus undiverted patients. The odds of having stricture (odds ratio (OR) = 17.08, P < 0.001) and small bowel obstruction (OR = 5.05, P = 0.02) were both significantly higher in diverted patients. The average cost per patient was $43,000 more in the routinely diverted patients.

CONCLUSION

Undiverted restorative proctocolectomy may be the highest value procedure with the most favorable outcomes at the lowest cost.

Previous infliximab therapy and postoperative complications after proctocolectomy with ileum pouch anal anastomosis

BACKGROUND AND AIMS

It is unclear whether infliximab treatment induces increased complication rates after surgery for ulcerative colitis. Aim was to compare complication rates after pouch surgery in refractory ulcerative colitis patients with versus without previous infliximab therapy.

METHODS

We performed a retrospective study evaluating all patients who underwent an ileoanal J-pouch for refractory ulcerative colitis over a four-year period. Postoperative complications, infliximab use and time between last infliximab administration and restorative surgery were assessed. 1-stage procedures (proctocolectomy with pouch, with or without temporary diversion) and 2-stage procedures (emergency colectomy and subsequent completion proctectomy with pouch, with or without temporary diversion) were analyzed separately.

RESULTS

Seventy-two patients were included; 33 underwent 1-stage procedure and 39 had 2-stage surgery. In the 1-stage group, 21 patients (64%) had previous infliximab therapy (median time between last infusion and surgery: 7.1 months (IQR 2.6-8.3)). Infliximab-treated patients had higher incidence of pelvic sepsis (5/21 vs. 0/12; risk difference 24%; 95% CI: 6 to 42, p=0.067) and non-infectious complications (8/21 vs. 1/12; risk difference 30%; 95% CI: 4 to 56, p=0.065). In the 2-stage group, 17 (44%) had previous infliximab therapy (median time between last infusion and surgery: 11.8 months (IQR 7.3-15.5)). Total, infectious, non-infectious complication rates and pelvic sepsis rates were similar for infliximab and non-infliximab patients in the 2-stage group.

CONCLUSIONS

This small study suggests that infliximab use prior to 1-stage restorative proctocolectomy in patients with UC is associated with increased incidence of pelvic sepsis. A 2-stage procedure in these patients should be considered.

The pediatric pouch in inflammatory bowel disease: a primer for the gastroenterologist

Pediatric severe ulcerative colitis that is resistant to current medical treatment can successfully be managed surgically with a colectomy, ileal pouch creation and pouch-anal anastomosis. Key issues that should be considered and discussed before the pouch option can be offered include alternative surgical procedures, pouch function expectations, risk of surgical leak, pelvic sepsis, anastomotic strictures, acute and chronic pouch inflammation, Crohn's disease of the pouch and risk of reduced fertility for females. A long-term risk is malignancy of the residual colonic tissue. The decision to proceed with a pouch or not poses a substantial emotional burden to the child and family. Despite the risk of surgical complications and pouch inflammatory and functional challenges, the overwhelming majority of children and their families are satisfied with their pouch surgery outcomes. Further study is needed to assess preoperative risk predictors, prevention and treatment of complications.

Ulcerative colitis

Ulcerative colitis is an idiopathic, chronic inflammatory disorder of the colonic mucosa, which starts in the rectum and generally extends proximally in a continuous manner through part of, or the entire, colon; however, some patients with proctitis or left-sided colitis might have a caecal patch of inflammation. Bloody diarrhoea is the characteristic symptom of the disease. The clinical course is unpredictable, marked by alternating periods of exacerbation and remission. In this Seminar we discuss the epidemiology, pathophysiology, diagnostic approach, natural history, medical and surgical management, and main disease-related complications of ulcerative colitis, and briefly outline novel treatment options. Enhanced understanding of how the interaction between environmental factors, genetics, and the immune system results in mucosal inflammation has increased knowledge of disease pathophysiology. We provide practical therapeutic algorithms that are easily applicable in daily clinical practice, emphasising present controversies in treatment management and novel therapies.

[Current status of elective surgical treatment of ulcerative colitis. A systematic review]

Despite recent advances in the medical treatment of ulcerative colitis (UC), approximately 25-40% of patients will need surgery during their disease. The aim of elective surgical treatment of UC is to remove the colon/and rectum with minimal postoperative morbidity, and to offer a good long-term quality of life. There are several technical options for the surgical treatment of UC; at present, the most frequently offered is restorative proctocolectomy and ileal pouch-anal anastomosis. Both the surgeon and patient should be aware of the risks associated with a technically demanding procedure and possible postoperative complications, including the possibility of infertility, permanent stoma, or several surgical procedures for pouch-related complications. A precise knowledge of each surgical technique, and its indications, complications, long-term risks and benefits is useful to offer the best surgical option tailored to each patient. We searched in PubMed, MEDLINE, and EMBASE for all kinds of articles (all the publications until April 2012). Papers on Crohn's disease, indeterminate colitis, or other forms of colitis were excluded from the review. We reviewed the abstracts and identified potentially relevant articles. MeSH words were used as search, "ulcerative colitis", "surgery", "indications", "elective surgery", "colectomy," "proctocolectomy," "laparoscopy", "Complications," "outcome", "results" "quality of life". One hundred and four articles were included in this review.

A comprehensive review of inflammatory bowel disease focusing on surgical management

The two main diseases of inflammatory bowel disease are Crohn's disease and ulcerative colitis. The pathogenesis of inflammatory disease is that abnormal intestinal inflammations occur in genetically susceptible individuals according to various environmental factors. The consequent process results in inflammatory bowel disease. Medical treatment consists of the induction of remission in the acute phase of the disease and the maintenance of remission. Patients with Crohn's disease finally need surgical treatment in 70% of the cases. The main surgical options for Crohn's disease are divided into two surgical procedures. The first is strictureplasty, which can prevent short bowel syndrome. The second is resection of the involved intestinal segment. Simultaneous medico-surgical treatment can be a good treatment strategy. Ulcerative colitis is a diffuse nonspecific inflammatory disease that involves the colon and the rectum. Patients with ulcerative colitis need surgical treatment in 30% of the cases despite proper medical treatment. The reasons for surgical treatment are various, from life-threatening complications to growth retardation. The total proctocolectomy (TPC) with an ileal pouch anal anastomosis (IPAA) is the most common procedure for the surgical treatment of ulcerative colitis. Medical treatment for ulcerative colitis after a TPC with an IPAA is usually not necessary.

Surgical treatment of ulcerative colitis in the biologic therapy era

Recently introduced in the treatment algorithms and guidelines for the treatment of ulcerative colitis, biological therapy is an effective treatment option for patients with an acute severe flare not responsive to conventional treatments and for patients with steroid dependent disease. The reduction in hospitalization and surgical intervention for patients affected by ulcerative colitis after the introduction of biologic treatment remains to be proven. Furthermore, these agents seem to be associated with increase in cost of treatment and risk for serious postoperative complications. Restorative proctocolectomy with ileal pouch-anal anastomosis is the surgical treatment of choice in ulcerative colitis patients. Surgery is traditionally recommended as salvage therapy when medical management fails, and, despite advances in medical therapy, colectomy rates remain unchanged between 20% and 30%. To overcome the reported increase in postoperative complications in patients on biologic therapies, several surgical strategies have been developed to maintain long-term pouch failure rate around 10%, as previously reported. Surgical staging along with the development of minimally invasive surgery are among the most promising advances in this field.

Role of ileostomy in restorative proctocolectomy

Restorative proctocolectomy (RP) is the treatment of choice in patients affected with refractory ulcerative colitis or familial adenomatous polyposis. Surgery in elective settings is often performed in 2 stages, fashioning an ileostomy which is closed 2-3-mo later. It is still debated whether omitting ileostomy could offer advantages in the management of patients undergoing RP.

Intraoperative, postoperative and reoperative problems with ileoanal pouches

BACKGROUND

Proctocolectomy with ileal pouch-anal anastomosis (IPAA) has been developed and refined since its introduction in the late 1970s. Nonetheless, it is a procedure associated with significant morbidity. The aim of this review was to provide a structured approach to the challenges that surgeons and physicians encounter in the management of intraoperative, postoperative and reoperative problems associated with ileoanal pouches.

METHODS

The review was based on relevant studies identified from an electronic search of MEDLINE, Embase and PubMed databases from 1975 to April 2011. There were no language or publication year restrictions. Original references in published articles were reviewed.

RESULTS

Although the majority of patients experience long-term success with an ileoanal pouch, significant morbidity surrounds IPAA. Surgical intervention is often critical to achieve optimal control of the situation.

CONCLUSION

A structured management plan will minimize the adverse consequences of the problems associated with pouches.

Restorative proctocolectomy without diverting ileostomy in children with ulcerative colitis

PURPOSE

The safety of performing a restorative proctocolectomy (RP) and J-pouch ileoanal anastomosis (IPAA) without diverting ileostomy for children with ulcerative colitis (UC) is a subject of extensive debate. Our goal was to examine pediatric outcomes of RP and IPAA without ileostomy.

METHODS

We performed a single-institution review of UC patients who had RP and IPAA with (+Ostomy) or without (-Ostomy) diverting ileostomy from 2002 to 2010. Surgeon and patient preference determined ileostomy decision. The study included 50 patients (28 +Ostomy, 22 -Ostomy).

RESULTS

Preoperative demographics were similar between 2 groups in age (13.5 ± 3.5 years -Ostomy, 14.3 ± 3 years +Ostomy), serum albumin (3.6 ± 0.7 -Ostomy, 3.6 ± 0.7 +Ostomy), body mass index (20.8 ± 6.9 -Ostomy, 21.3 ± 8.6 +Ostomy), and daily corticosteroid dose (22.4 ± 17.7 mg -Ostomy, 23.5 ± 13.7 mg +Ostomy). Operating time was less in -Ostomy with mean times of 6:22 ± 2:04 vs 9:07 ± 2:57. The -Ostomy group required fewer ileoanal anastomotic dilations per patient (0.4 ± 0.8 vs 1.4 ± 1.9). Functional outcomes were not significantly different regarding pouchitis episodes per patient (0.6 ± 1.1 -Ostomy, 0.6 ± 1.1 +Ostomy), daily bowel movements (5.5 ± 1.9 -Ostomy, 6.7 ± 4.0 +Ostomy), and daily postoperative loperamide dose (8.4 ± 4.3 mg -Ostomy, 6.8 ± 4.0 mg +Ostomy).

CONCLUSION

Short- and long-term outcomes can be equivalent in patients with and without diverting ileostomy, but questions remain regarding patient selection and quality of life impact.

Surgical management of ulcerative colitis: a comparison of Canadian and American colorectal surgeons

BACKGROUND

Ileal pouch anal anastomosis (IPAA) to surgically manage ulcerative colitis may involve multiple separate surgical procedures, impacting treatment costs, length of stay in hospital, complication rates and patient outcomes, and there is currently no accepted standard of care regarding the number of stages that should be performed. The purpose of this study was to compare the practice patterns of Canadian and American colorectal surgeons regarding the surgical management of ulcerative colitis.

METHODS

A questionnaire was mailed to all practisng fellows of the American Society of Colon and Rectal Surgeons (ASCRS) in Canada and the United States. Surgeons were asked to describe their typical practices for 3 clinical scenarios.

RESULTS

Questionnaires were mailed to 40 Canadian and 873 American ASCRS fellows with response rates of 86% and 62%, respectively. In the case of a patient who has had a prior colectomy, who is not taking steroids and in whom a tension-free IPAA is possible, 44% of Canadian surgeons would perform IPAA alone and 56% would perform IPAA with a loop ileostomy. In contrast, only 26% of American surgeons would perform IPAA alone and 74% would perform IPAA with a loop ileostomy (p = 0.002). In the case of a patient who has not had previous surgery, who is taking 10 mg/day of prednisone and in whom a tension-free IPAA is possible, the majority of both Canadian and American surgeons would perform an IPAA with a loop ileostomy (93% and 89%, respectively, p = 0.06). In the case of a patient who has not had previous surgery, who is taking 40 mg/day of prednisone and in whom a tension-free IPAA is possible, 45% of Canadian surgeons would perform a subtotal colectomy with an end ileostomy compared with 14% of American surgeons (p < 0.001).

CONCLUSION

There are significant differences in the surgical management of ulcerative colitis between Canadian and American colorectal surgeons.

Impact of defunctioning loop ileostomy on outcome after restorative proctocolectomy for ulcerative colitis

PURPOSE

This study analyzes the impact of a temporary loop ileostomy on postoperative outcome after restorative proctocolectomy for ulcerative colitis in terms of complications and reoperations including ileostomy closure.

METHODS

The records of 122 consecutive patients undergoing restorative proctocolectomy for ulcerative colitis during a 12-year period were reviewed. In 89 patients, a defunctioning ileostomy was created, while 33 patients had no ileostomy. Statistics were done with Chi-square test and Mann-Whitney U test, p < 0.05 considered significant.

RESULTS

Both study groups were comparable concerning age, colitis activity, previous diseases, previous surgery, use of steroids, and immunosuppressives. Pouch-related septic complications (anastomotic dehiscence, pouch leakage, pelvic abscess) were significantly lower in the ileostomy group (5.6% vs. 18.2%, p = 0.031), resulting in a lower rate of emergency laparotomies following restorative proctocolectomy (4.5% vs. 30.3%, p < 0.001). Including all complications associated with scheduled closure of ileostomy, the cumulative frequency of emergency laparotomies was significantly lower in the ileostomy group (13.5% vs. 30.3%, p = 0.032). The cumulative duration of hospitalization, including all hospital stays for complications or closure of the ileostomy, was significantly longer in the ileostomy group [median 22 days (11-92) vs. 14 days (9-109), p < 0.001]. During long-term follow-up, a stricture at the pouch-anal anastomosis was more common in the ileostomy group (24.7% vs. 6.1%, p = 0.021), whereas only one stricture necessitated surgical therapy.

CONCLUSIONS

Creation of a defunctioning loop ileostomy reduces pouch-related septic complications and the frequency of emergency second laparotomies after restorative proctocolectomy for ulcerative colitis.

Diverting loop ileostomy after restorative proctocolectomy: predictors of poor outcome and poor quality of life

AIM

Diverting loop ileostomy is used to minimize the impact of anastomotic complication after restorative proctocolectomy (RPC). However, the ileostomy itself may have complications and therefore affect quality of life (QOL). The aim of this study was to analyse the predictors of complications of the ileostomy formation and closure and of the QOL of these patients.

METHOD

Forty-four consecutive patients who underwent RPC were enrolled. Records of the ileostomy follow-up were retrieved from a prospectively collected database and QOL was assessed with the Stoma-QOL questionnaire. Ileostomy site coordinates were measured. Univariate and multivariate analysis were performed.

RESULTS

In this series, three patients experienced peristomal herniae, two ileostomy stenosis, seven ileostomy retraction and fourteen peristomal dermatitis. Emergency surgery was the only predictor of parastomal hernia (P = 0.017). Stenosis correlated with the distance from the umbilicus (tau = 0.24, P = 0.021). Use of standard rod and retraction were independent predictors of peristomal dermatitis (P = 0.049 and P = 0.001). Stoma-QOL was directly correlated to the age of the patients and to the occurrence of parastomal hernia (P = 0.001 and P = 0.021, respectively). After stoma closure, two patients reported wound sepsis and seven suffered obstructive episodes.

CONCLUSION

The predictors of negative outcome after construction of a diverting loop ileostomy after RPC were urgent surgery, use of standard rod, the distance of the stoma site from the umbilicus, parastomal herniae and the older age of patients.

Reoperative inflammatory bowel disease surgery

With the advent of restorative proctocolectomy or ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC), not only has there been potential for cure of UC but also patients have enjoyed marked improvements in bowel function, continence, and quality of life. However, IPAA can be complicated by postoperative small bowel obstruction, disease recurrence, and pouch failure secondary to pelvic sepsis, pouch dysfunction, mucosal inflammation, and neoplastic transformation. These may necessitate emergent or expeditious elective reoperation to salvage the pouch and preserve adequate function. Local, transanal, and transabdominal approaches to IPAA salvage are described, and their indications, outcomes, and the clinical parameters that affect the need for salvage are discussed. Pouch excision for failed salvage reoperation is reviewed as well. Relaparotomy is also frequently required for recurrent Crohn's disease (CD), especially given the nature of this as yet incurable illness. Risk factors for CD recurrence are examined, and the various surgical options and margins of resection are evaluated with a focus on bowel-sparing policy. Stricturoplasty, its outcomes, and its importance in recurrent disease are discussed, and segmental resection is compared with more extensive procedures such as total colectomy with ileorectal anastomosis. Lastly, laparoscopy is addressed with respect to its long-term outcomes, effect on surgical recurrence, and its application in the management of recurrent CD.

Technical aspects of ileoanal pouch surgery

Ileal pouch-anal anastomosis has become the surgical procedure of choice for chronic ulcerative colitis. Since the initial description of the technique, various modifications have facilitated its evolution into a safe operation with excellent long-term outcomes. However, some aspects of the operation remain contentious. Our aim is to describe the technical aspects of ileal pouch-anal anastomosis and review the current literature in the areas of controversy.

The effect of peri-stomal infiltration with bupivacaine/epinephrine on post-operative pain, nausea and ease of surgery in reversal of loop ileostomies

PURPOSE

Evidence to support the routine use of local anaesthetic in the reversal of loop ileostomy is equivocal. This randomized control study looked at the use of peri-operative infiltration of stoma with 0.25% bupivacaine with 1/200,000 epinephrine on the ease of surgery and its effect on post-operative pain and nausea.

METHODS

Sixty patients were randomized to receive peri-stomal infiltration with either 0.25% bupivacaine with 1/200,000 epinephrine or normal saline. The surgeon graded the surgery as straightforward, intermediate or difficult, and the time for the operation was also recorded. Post-operatively, analgesia was provided via PCA for 24 h. Post-operative pain and nausea scores and total morphine usage median (inter-quartile range) were compared using the Mann-Whitney U test with p < 0.05 considered significant.

RESULTS

There was no difference between the local anaesthetic groups and controls with respect to opiate consumption (p = 0.4), post-operative pain (p = 0.72) or nausea (p = 0.78). Shorter total anaesthetic and operative times were noted in study group, but this was not significant (p = 0.55). However, surgery was found to be easier in the local anaesthetic group (p = 0.0046).

CONCLUSION

Peri-stomal infiltration with 0.25% bupivacaine with 1/200,000 epinephrine does not impact on post-operative pain and nausea scores or opiate analgesia use. However, its use is recommended as an aid to dissection in surgery.

Laparoscopic versus open proctocolectomy with ileal pouch‐anal anastomosis

In recent years laparoscopic proctocolectomy with ileal pouch-anal anastomosis has been used as an alternative to conventional open techniques. Since many published series on proctectomy and ileal pouch-anal anastomosis are based on open experience, in this paper we compare our laparoscopic experience on 21 patients with ulcerative colitis (UC) or familial adenomatous polyposis (FAP) to 25 patients who had undergone open proctocolectomy with ileal pouch-anal anastomosis. The median operative time in the laparoscopic group was significantly longer than that in the open group (325 min vs. 220 min). However, blood loss was less (115 ml vs.240 ml), bowel function returned earlier (2 days vs.4 days), and hospitalization time was shorter (9 days vs.11 days) in the laparoscopic group (all p<0.05). Early postoperative complications were encountered in five patients of the laparoscopic group and in seven patients of the open group. The median follow-up time was 15 months (range 6-34) in both groups. Late postoperative complications were encountered in three patients of the laparoscopic group and in three patients of the open group. In conclusion, laparoscopic proctocolectomy with ileal pouch-anal anastomosis is technically feasible. The technique described in this study provides the advantages of less blood loss, shorter hospitalization, quicker return of bowel function and more favorable cosmetic results when compared to the open technique.

Proximal diversion at the time of ileal pouch-anal anastomosis for ulcerative colitis: current practices of North American colorectal surgeons

PURPOSE

Pelvic sepsis is a serious complication after ileal pouch-anal anastomosis for ulcerative colitis that may lead to pouch failure or poor function. Although a temporary loop ileostomy may be created at the time of ileal pouch-anal anastomosis to prevent or minimize the consequences of an anastomotic leak, research has suggested that an ileostomy can be safely omitted in selected patients. The purpose of this study was to examine the use of proximal diversion by colorectal surgeons at the time of ileal pouch-anal anastomosis for ulcerative colitis.

METHODS

A questionnaire was mailed to all practicing fellows of The American Society of Colon and Rectal Surgeons in North America. Surgeons were asked to describe their typical practice for a number of clinical scenarios.

RESULTS

Questionnaires were mailed to 913 American Society of Colon and Rectal Surgeons fellows, and 63 percent responded. For a patient who has had a prior colectomy and is not taking steroids, 27 percent of surgeons would perform ileal pouch-anal anastomosis alone, and 73 percent would perform ileal pouch-anal anastomosis with a loop ileostomy. For a patient who has not had previous surgery and is taking prednisone 40 mg/day, 16 percent of surgeons would perform a subtotal colectomy with an end ileostomy, 82 percent would perform a total proctocolectomy and ileal pouch-anal anastomosis with a loop ileostomy, and 2 percent would perform a total proctocolectomy and ileal pouch-anal anastomosis without an ileostomy. There was no relationship between practice setting, annual ileal pouch-anal anastomosis volume, or years in practice and surgeon response for either scenario.

CONCLUSIONS

The majority of surgeons create a temporary loop ileostomy at the time of ileal pouch-anal anastomosis for ulcerative colitis.

The ileal pouch anal anastomosis: to divert or not to divert? The case for diversion

The ileal pouch anal anastomosis is a high-risk anastomosis with a high rate of complications. Because of this proximal diversion has often been done when performing this operation. Recently the practice of proximal diversion has been questioned, noting the high rate of complications associated with the stoma and stomal reversal. However, the cumulative data does suggest that an undiverted ileal pouch anal anastomosis has a higher leak rate and is associated with increased pelvic sepsis. Because of the severity of this complication proximal diversion is still advocated in the majority of cases.

A selective approach to restorative proctocolectomy without ileostomy: a single centre experience

OBJECTIVE

A single surgeon series on complications and functional outcomes following restorative proctocolectomy (RPC) is presented.

METHOD

An ethically-approved database was used to collect data on all patients undergoing RPC at a single institution. Patient demographics, operative details, complications and functional outcomes were assessed. The impact of ileostomy omission on outcomes was also assessed.

RESULTS

Two hundred patients undergoing RPC between 1987 and 2006 were included. There were 122 (61.0%) males and the mean age at surgery was 37.6 years. A J pouch was constructed in 199 (99.5%) patients and an ileostomy omitted in 160 (80.0%). Since adopting a selective policy after the 36th consecutive patient in the series, only 9 (5.5%) patients have had an ileostomy constructed at the time of pouch construction. Complications occurred in 112 (56.3%) patients, with anastomotic stricture (20.6%) and pouchitis (28.6%) being the most common. Anastomotic stricture was more common in those patients receiving an ileostomy (43.6%vs 15.0%, P < 0.001), as were pouch-cutaneous fistulae (5.1%vs 0.6%, P = 0.039) and pelvic sepsis (15.4%vs 5.0%, P = 0.023). Functional outcomes were good, with median 24-h stool frequency of five motions at 1 year. There was increased urgency to defaecate which in part may be due to a significant decline in the use of antidiarrhoeal medication during follow up.

CONCLUSIONS

Selective omission of a covering ileostomy in most cases can produce good results following RPC with no increase in the risk of septic complications or pouch failure, and a decreased risk of anastomotic stricture, with maintenance of good function in the majority.

Surgery for inflammatory bowel disease

Despite the new and ever expanding array of medications for the treatment of inflammatory bowel disease (IBD), there are still clear indications for operative management of IBD and its complications. We present an overview of indications, procedures, considerations, and controversies in the surgical therapy of IBD.

Ten years experience of one-stage restorative proctocolectomy for ulcerative colitis

BACKGROUND

Ileal-pouch anal anastomosis has an established role in the treatment of ulcerative colitis. Controversy exists regarding the routine use of a diverting ileostomy. The aim of this study was to review the clinical and functional outcome of patients undergoing restorative proctocolectomy in the absence of a diverting ileostomy (one-stage).

MATERIALS AND METHODS

Between 1990 and 1999, 87 patients with ulcerative colitis underwent a one-stage restorative proctocolectomy. The median age at the time of operation was 34 years (range 12-64 years) and median follow-up was 36 months (range 24-144 months). The clinical notes were reviewed retrospectively.

RESULTS

The median in-patient stay was 15 days (range 9-36). There were no post-operative deaths. The complication rate within 30 days of surgery approximated to 40%. The median daytime pouch evacuation rate was 5. Only 13% of patients had to empty their pouch at night on a regular basis. Pelvic sepsis secondary to anastomotic leakage was the most commonly encountered problem, occurring in 15 patients. Small bowel obstruction was encountered in ten patients. One pouch required excision for a recurrent pouch-vaginal fistula.

CONCLUSION

Despite refinements in the surgical technique, restorative proctocolectomy is associated with significant morbidity. For a selected group of patients undergoing an ileo-anal anastomosis, a defunctioning ileostomy may be avoided.

Ileal pouch surgery for ulcerative colitis

Ulcerative colitis (UC) is a relapsing and remitting disease characterised by chronic mucosal and submucosal inflammation of the colon and rectum. Treatment may vary depending upon the extent and severity of inflammation. Broadly speaking medical treatments aim to induce and then maintain remission. Surgery is indicated for inflammatory disease that is refractory to medical treatment or in cases of neoplastic transformation. Approximately 25% of patients with UC ultimately require colectomy. Ileal pouch-anal anastomosis (IPAA) has become the standard of care for patients with ulcerative colitis who ultimately require colectomy. This review will examine indications for IPAA, patient selection, technical aspects of surgery, management of complications and long term outcome following this procedure.
