Ileal pouch-anal anastomosis in elderly patients: is there a difference in morbidity compared with younger patients?

Segmental Colectomy in Ulcerative Colitis

BACKGROUND

Segmental colectomy in ulcerative colitis is performed in select patients who may be at increased risk for postoperative morbidity.

OBJECTIVE

To identify patients with ulcerative colitis who underwent segmental colectomy and assess their postoperative and long-term outcomes.

DESIGN

Retrospective case series.

SETTING

A tertiary care IBD center.

PATIENTS

Patients with ulcerative colitis who underwent surgery between 1995 and 2022.

INTERVENTION

Segmental colectomy.

MAIN OUTCOME MEASURES

Postoperative complications, early and late colitis, metachronous cancer development, completion proctocolectomy-free survival rates, and stoma at follow-up.

RESULTS

Fifty-five patients were included (20 [36.4%] women; age 67.8 (57.4-77.1) years at surgery; BMI 27.7 (24.2-31.1) kg/m 2 ; median follow-up 37.3 months). Thirty-two patients (58.2%) had ASA score of 3, 48 (87.3%) had at least 1 comorbidity, and 48 (87.3%) had Mayo endoscopic subscores of 0 to 1. Patients underwent right hemicolectomy (n = 28; 50.9%), sigmoidectomy (n = 17; 30.9%), left hemicolectomy (6; 10.9%), low anterior resection (n = 2; 3.6%), or a nonanatomic resection (n = 2; 3.6%) for endoscopically unresectable polyps (n = 21; 38.2%), colorectal cancer (n = 15; 27.3%), symptomatic diverticular disease (n = 13; 23.6%), and stricture (n = 6; 10.9%). Postoperative complications occurred in 16 patients (29.1%; n = 7 [12.7%] Clavien-Dindo class III-V). Early and late postoperative colitis rates were 9.1% and 14.5%, respectively. Metachronous cancer developed in 1 patient. Four patients (7.3%) underwent subsequent completion proctocolectomy with ileostomy. Six patients (10.9%) had a stoma at follow-up. Two- and 5-year completion proctocolectomy-free survival rates were 91% and 88%, respectively.

LIMITATIONS

Retrospective study and small sample size.

CONCLUSIONS

Segmental colectomy in ulcerative colitis is associated with low postoperative complication rates, symptomatic early colitis and late colitis rates, metachronous cancer development, and the need for subsequent completion proctocolectomy. Therefore, it can be safe to consider select patients, such as the elderly with quiescent colitis and other indications, for colectomy. See Video Abstract .

Ileal Pouch-Anal Anastomosis in the Older Adult: a Review of Postoperative Outcomes and Pouchitis Treatment

PURPOSE OF REVIEW

Ileal pouch-anal anastomosis (IPAA) has become the preferred surgical treatment for patients with medically refractive ulcerative colitis (UC). Previous studies have suggested that outcomes of this procedure may be worse in older patients; however, more recent reports have suggested that IPAA in select patients is safe, feasible, and results in good quality of life. In this review, we discuss the recent literature surrounding clinical considerations and treatment management of IPAA in older adults.

RECENT FINDINGS

IPAA complication rates and adverse events are similar in the older adult population, as compared to the younger adult patient population. Although fecal urgency and incontinence may be more common among older adults, chronological age alone is not a contraindication for IPAA surgery, as good quality of life can still be achieved. In this review, we will also discuss the development of pouchitis after IPAA, particularly among older adults, as the emergence of newer biologic drugs has shifted the treatment landscape.

SUMMARY

IPAA can be a safe and effective treatment modality for older adults with UC, with high self-reported patient satisfaction. Patient optimization and careful case selection are vital to achieving these outcomes, and specialized preoperative assessments and counseling can help facilitate the proper treatment.

Restorative proctocolectomy with ileal pouch-anal anastomosis in elderly patients - is advanced age a contraindication?

Aim

We aimed to determine pouch function and retention rate for restorative proctocolectomy with ileal pouch‐anal anastomosis (IPAA) for ulcerative colitis (UC) in elderly patients.

Methods

We identified patients over 50 years old subjected to IPAA for confirmed pathological UC from 1980 until 2016. Patients were grouped according to age: 50–59, 60–69 and 70+ years. Short and long‐term outcomes and quality of life (QOL) were compared among the groups.

Results

Six hundred and one patients were identified (399 (66.4%) between 50–59 181 (30.1%) between 60–69, and 21 (3.5%) over 70 years of age). More males were in the 70+ arm, and more two‐stage procedures were performed in this group. Wound infection increased with age (P = 0.023). There was a trend of more fistula and pouchitis in the 70+ patients (P = 0.052 and P = 0.055, respectively). Pouch failure rate increased with age, and it was statistically significant in the 70+ cohort (P = 0.015). Multivariate stepwise logistic regression showed that pelvic sepsis (HR 4.8 (95% CI 1.5–15.4), P = 0.009), fistula (HR 6.0 (95% CI 1.7–21.5), and mucosectomy with handsewn anastomosis (HR 4.5 (95% CI 1.4–14.7)), were independently associated with pouch failure. No difference was observed in the QOL among the groups, but pouch function was better for patients younger than 60 years.

Conclusion

In elderly patients with UC, IPAA may be offered with reasonable functional outcomes, and ileal pouch retention rates, as an alternative to the permanent stoma. Stapled anastomosis increases the chance of pouch retention and should be recommended as long as the distal rectum does not carry dysplasia.

Ileal pouch-anal anastomosis in the elderly: A systematic review and meta-analysis

AIM

Despite good overall outcomes in most patients undergoing ileal pouch-anal anastomosis (IPAA), there is still hesitation about performing an IPAA in older patients due to the comorbidity burden and concern about incontinence. The aim of this work was to identify short- and long-term outcomes in older patinets undergoing IPAA to determine the perioperative safety and long-term functional success of IPAA in older patients.

METHOD

A literature search was performed for all publications on IPAA in adults aged ≥50 years that reported short- and long-term outcomes. Data extraction included demographics, 30-day outcomes, long-term functional outcomes and pouch failure. Data were further separated by age group (50-65 and ≥65 years). Outcomes were compared between age groups. Study quality and risk of bias was assessed using the Newcastle-Ottawa Scale.

RESULTS

Of 1053 publications reviewed, 13 full papers were included in the analysis. The overall 30-day morbidity and mortality rates were 47.3% and 1.3%, respectively. Thirty-day postoperative rates of small bowel obstruction and pelvic sepsis were 7.6% and 9.9%, respectively. After a median follow-up time of 62 months, rates of pouchitis, incontinence and pouch failure were 13.9%, 17.5% and 7.5%, respectively. There was no statically significant difference in rates of short- or long-term functional outcomes based on age 50-65 versus ≥65 years.

CONCLUSION

Increasing age did not increase the rate of short- or long-term outcomes, including pouch failure. These data suggest that the decision for IPAA construction should not be based on age alone.

Restorative surgery for ulcerative colitis in the elderly: an analysis of ileal pouch-anal anastomosis procedures from the American College of Surgeons National Surgical Quality Improvement Program

BACKGROUND

Ileal pouch-anal anastomosis (IPAA) for ulcerative colitis(UC) can be performed as either 2- or 3-stage procedure. IPAA in the elderly has been reported as safe and feasible, but little work to date has assessed outcomes by procedure. The aim of our study was to assess use and short-term outcomes of 2- and 3-stage IPAA in older adults.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was searched for ≥ 65-year-old patients who underwent IPAA for UC in 2- or 3-stage from 2012 to 2016. The primary endpoint was the rate and trends of the two approaches over time. Secondary endpoints included 30-day adverse events and complication-associated costs.

RESULTS

Overall, 123 patients were included: 77.5% (n = 83) 2-stage and 40 (32.5%) 3-stage IPAA. Mean age was 68.7 ± 3.9 years, with 43 (34.9%) women. The use of the 3-stage IPAA increased over time (18.8% in 2012 vs. 33.3% in 2016), with decreasing use of 2-stage IPAA(81.3% vs. 66.7%, p < 0.001). The morbidity associated with the procedures decreased over time, overall (81.3% in 2012 and 51.5% in 2016, p < 0.001) and in each group individually. No differences were observed in postoperative complications across groups (45.8% 2-stage, 32.5% 3-stage). The overall mean costs of care when no postoperative complications occurred was $25,910, vs. $38,577 when any complication occurred (p < 0.001), but no differences were observed between groups.

CONCLUSIONS

In a national analysis, there was a trend of increasing 3-stage vs. 2-stage IPAA for UC in older Americans. Complications and complication-associated costs were comparable across approaches, suggesting that the choice of procedure type should be based on the specific patient comorbidities and surgeon preferences.

Elderly patients with inflammatory bowel disease: Updated review of the therapeutic landscape

High-quality data remains scarce in terms of optimal management strategies in the elderly inflammatory bowel disease (IBD) population. Indeed, available trials have been mostly retrospective, of small sample size, likely owing to under-representation of such a population in the major randomized controlled trials. However, in the last five years, there has been a steady increase in the number of published trials, helping clarify the estimated benefits and toxicity of the existing IBD armamentarium. In the Everhov trial, prescription strategies were recorded over an average follow-up of 4.2 years. A minority of elderly IBD patients (1%-3%) were treated with biologics within the five years following diagnosis, whilst almost a quarter of these patients were receiving corticosteroid therapy at year five of follow-up, despite its multiple toxicities. The low use of biologic agents in real-life settings likely stems from limited data suggesting lower efficacy and higher toxicity. This minireview will aim to highlight current outcome measurements as it portends the elderly IBD patient, as well as summarize the available therapeutic strategies in view of a growing body of evidence.

Outcomes and Management of the Ileal Pouch-Anal Anastomosis in the Elderly

PURPOSE OF REVIEW

Ileal pouch-anal anastomosis (IPAA) is the preferred surgical treatment for patients undergoing colectomy to maintain intestinal continuity. Earlier studies have suggested that outcomes are worse in elderly patients who underwent IPAA. However, more recent reports have shown that IPAA outcomes in the elderly are comparable to younger patients. We review the recent medical literature regarding outcomes and treatments for common complications in elderly IPAA patients.

RECENT FINDINGS

Compared to younger patients, IPAA in the elderly is not associated with increased major surgical complications, but is associated with increased length of stay and re-admission rate for dehydration in older patients. Rates of fecal incontinence after IPAA were similar between younger and older patients. Sacral nerve stimulation has shown early promise as a possible treatment for fecal incontinence after IPAA, but more research is needed. Pouchitis is a common complication, and antibiotics remain first-line treatment options. Other treatment options include mesalamines, steroids, immunomodulators, and biologics. The efficacy of newer biologics such as vedolizumab and ustekinumab has been reported, but more data is needed. IPAA is safe in the elderly with high self-reported patient satisfaction. However, the elderly IPAA patient warrants special consideration regarding outcomes and management.

The Impact of Age at Time of Ileal Pouch Anal Anastomosis on Short and Long-Term Outcomes in Adults

BACKGROUND

There is limited knowledge on ileal pouch anal anastomosis (IPAA) function when performed on patients older than age 50 years. The aim of this study was to determine if surgery on those older than age 50 years impacts short-term complications or long-term function.

METHODS

A retrospective review of all patients undergoing IPAA for chronic ulcerative colitis at a single tertiary referral center between 2002 and 2013 was conducted. Short-term postoperative complications and long-term function and quality of life were analyzed according to age at pouch formation (age >50 vs age ≤50 years).

RESULTS

A total of 911 patients who underwent IPAA (542 male) were included, with 178 patients (20%) age >50 years and 733 (80%) ≤50 years. Patients >50 years had higher American Society of Anesthesiology score (ASA) scores and increased rates of obesity and dysplasia or cancer at the time of colectomy, and were less often on steroids (all P < 0.01). Over a median follow-up of 5 years, older patients reported increased daytime incontinence (60% vs 37%, P < 0.01) and pad usage (34% vs 11%, P < 0.01) at up to 1.5 years post-IPAA, after which time the groups became similar. Other functional outcomes, including pouch failure and quality of life, were similar between the 2 groups across the follow-up periods.

CONCLUSION

Performing an IPAA on carefully selected patients older than age 50 years has minor, transient differences in pouch function compared with patients younger than age 50 years. Assuming appropriate patient selection, IPAA should continue to be offered to older patients without increased risk of compromised function or of pouch failure.

Surgery in ulcerative colitis: When? How?

Ulcerative Colitis (UC) is an idiopathic chronically-remitting inflammatory bowel disorder characterized by a contiguous inflammation of the colonic mucosa affecting the rectum that generally extends proximally in a continuous manner through the entire colon. Patients typically experience intermittent exacerbations, with symptoms characterized by bloody diarrhea associated with urgency and tenesmus. The anatomical extent of mucosal involvement is the most important factor determining disease course and is an important predictor of colectomy. The precise etiology of UC is unknown. However, a combination of genetic predisposition and environmental factors seems to have a key role in the development of the disease. UC usually is mildly active but it can be a life-threatening condition because of colonic and systemic complications, and later in the disease course due to the development of colorectal cancer. Interestingly, even if pathogenetic features detected in patients with sporadic CRC can be also found in UC-related colorectal cancer (UC-CRC), this latter is, usually, driven by an inflammation-driven pathway rising from a non-neoplastic inflammatory epithelium to dysplasia to cancer. Thus, a long-term follow-up with colonoscopy surveillance has been recommended. Approximately 15% of UC patients develop an acute attack of severe colitis, and 30% of these patients require colectomy. The initial treatment strategy in UC typically follows the traditional step-up approach. One third of the patients will not respond to steroid therapy and cyclosporine and infliximab are the most common salvage agents employed in these cases in order to avoid emergent surgery. Unfortunately, although a significant short-term benefit have been observed after infliximab treatment, the colectomy rate have remained stable. Surgery in UC depends on the stage of the disease as well as patient's status and is divided into the following settings: urgent, emergent and elective. Despite many efforts the surgical management of UC remains a significant challenge. A multidisciplinary management of UC is key in order to define the best timing and the best procedure for each patient in an individualized basis.

Preoperative optimization of patients with inflammatory bowel disease undergoing gastrointestinal surgery: a systematic review

PURPOSE

Surgical management of inflammatory bowel disease (IBD) is a challenging task. The aim of preoperative optimization (PO) is to decrease the risk of complications and reduce the length of postoperative stay. The aim of this study was to review and grade the available evidence, attain clear recommendations, and point out potential future research.

METHODS

Studies were identified from electronic databases (PubMed, Embase, and Cochrane Library) and scanning reference lists in relevant papers. English-written studies examining PO in adult patients with IBD were included. Eight PO factors were investigated.

RESULTS

Management of IBD is a multidisciplinary task. Steroid withdrawal is recommended while steroid stress dose is not recommended. Thiopurines appear to be safe, but it may be prudent to plan the procedure remotely from the last dose of an anti-TNF agent. Nutritional risk screening is recommended to unveil and correct any malnutrition. Thrombosis prophylaxis prior to surgery is well supported by evidence while extended 4-week prophylaxis needs further research. Percutaneous ultrasound or CT-guided drainage for intra-abdominal abscesses is recommended, but it is unclear for how long supplementary antibiotics (ABs) should be used. Oral AB 24 h prior to open surgery might improve outcome if given as complementary to IV perioperative AB. Mechanical bowel preparation is not supported by evidence. Comorbidities must be treated accordingly prior to surgical intervention. Smoking cessation can be beneficial for wound healing.

CONCLUSION

Multimodel PO intervention in IBD patients is recommended.

Restorative Proctocolectomy in Elderly IBD Patients: A Multicentre Comparative Study on Safety and Efficacy

BACKGROUND AND AIMS

Restorative proctocolectomy in elderly inflammatory bowel disease [ IBD] patients is controversial and limited data are available on the outcomes of surgery. The aim of this study was to evaluate the safety, efficacy, and long-term results of ileal-pouch-anal anastomosis in elderly patients, in a multicentre survey from European referral centres.

METHODS

The International Pouch Database [IPD] combined 101 variables. Patients aged ≥ 65 years were matched on the basis of open versus laparoscopic surgery with a control group of consecutive younger unselected patients with a ratio of 1:2. Statistical analysis was performed using two-tailed t test, chi square and Fisher's exact tests, Kaplan-Meier function, and log-rank tests where appropriate.

RESULTS

In the IPD, 77 patients aged ≥ 65 years [Group A] and 154 control patients [Group B] were identified. Elderly patients had more comorbidities [p = 0.0001], longer disease duration [p = 0.001], less extensive disease [p = 0.006], more previous abdominal operations [p = 0.0006], surgery for cancer or dysplasia more frequently [p = 0.0001], fewer single-stage procedures [p = 0.03], more diversions after ileal pouch-anal anastomosis [IPAA] [p = 0.05], and a higher laparoscopic conversion rate [p = 0.04]. Postoperative complications and pouch failure were similar between the groups, but Group A had more Clavien-Dindo IV-V complications [p = 0.04], and longer length of stay [p = 0.007]. Laparoscopy was associated with a shorter duration of surgery [p = 0.0001], and length of stay [p = 0.0001], and the same complication rate as open surgery.

CONCLUSIONS

Restorative proctocolectomy can be performed in selected elderly patients, but there is a higher risk of postoperative complications and longer length of stay in this group. Laparoscopy is associated with shorter operating time and length of stay.

Pharmacological- and non-pharmacological therapeutic approaches in inflammatory bowel disease in adults

Inflammatory bowel diseases (IBDs) are a group of chronic inflammatory conditions mainly of the colon and small intestine. Crohn's disease (CD) and ulcerative colitis (UC) are the most frequent types of IBD. IBD is a complex disease which arises as a result of the interaction of environmental, genetic and immunological factors. It is increasingly thought that alterations of immunological reactions of the patients to their own enterable bacteria (microfilm) may contribute to inflammation. It is characterized by mucosal and sub mucosal inflammation, perpetuated by infiltration of activated leukocytes. CD may affect the whole gastrointestinal tract while UC only attacks the large intestine. The therapeutic goal is to achieve a steroid-free long lasting remission in both entities. UC has the possibility to be cured by a total colectomy, while CD never can be cured by any operation. A lifelong intake of drugs is mostly necessary and essential. Medical treatment of IBD has to be individualized to each patient and usually starts with anti-inflammatory drugs. The choice what kind of drugs and what route administered (oral, rectal, intravenous) depends on factors including the type, the localization, and severity of the patient's disease. IBD may require immune-suppression to control symptoms such as prednisolone, thiopurines, calcineurin or sometimes folic acid inhibitors or biologics like TNF-α inhibitors or anti-integrin antibodies. For both types of disease (CD, UC) the same drugs are available but they differ in their preference in efficacy between CD and UC as 5-aminosalicylic acid for UC or budesonide for ileocecal CD. As therapeutic alternative the main mediators of the disease, namely the activated pro-inflammatory cytokine producing leukocytes can be selectively removed via two apheresis systems (Adacolumn and Cellsorba) in steroid-refractory or dependent cases. Extracorporeal photopheresis results in an increase of regulatory B cells, regulatory CD8(+) T cells and T-regs Type 1. Both types of apheresis were able to induce clinical remission and mucosal healing accompanied by tapering of steroids.

Functional outcomes following ileal pouch-anal anastomosis (IPAA) in older patients: a systematic review

AIM

Ileal pouch-anal anastomosis (IPAA) is performed in ulcerative colitis or familial adenomatous polyposis with a view to restoration of GI continuity and prevention of permanent faecal diversion. Debate exists as to its safety in older patients. This review aims to assess functional outcomes and safety of restorative proctocolectomy (RPC) in older compared to younger patients.

METHODS

Literature search was performed for age-stratified studies which assessed functional outcomes of IPAA. Twelve papers were included overall. Patients were categorized into 'older' and 'younger' groups. Analysis was split into three separate parts: 1. Age cut-off of 50 ± 5 years (with sensitivity analysis); 2. Age cut-off of 65 ± years; 3. Long-term outcomes (>10 years).

RESULTS

With an age cut-off of 50 years (4327 versus 513 patients), complication rates were comparable with the exception of an increased rate of small-bowel obstruction in the younger patients (p = 0.034). At 1 year, 24-h stool frequency was significantly higher in the older patient group (p < 0.0001). Daytime (p < 0.0001) and night-time (p < 0.0001) incontinence rates were also significantly higher in older patients. Overall, function deteriorated with time across all ages; however, after 10 years, there was no significant difference in incontinence rates between age groups. Dehydration and electrolyte loss was a significant problem in patients over 65 (p < 0.0001). Despite differences in postoperative function, quality of life was comparable between groups; however, only a few studies reported quality of life data.

CONCLUSION

IPAA is safe in older patients, although treating clinicians should bear in mind the increased risk of dehydration. Postoperative function is worse in older patients, but seems to level out with time and does not appear to significantly impact on overall quality of life and patient satisfaction. Assessment for suitability for RPC should not be based on chronological age in isolation. It is imperative that the correct support is given to older patients with worsened postoperative function in order to maintain patient satisfaction and adequate quality of life.

Total proctocolectomy for rectal cancer in Lynch syndrome: indications and considerations

SUMMARY 

Patients with Lynch syndrome and rectal cancer present a unique clinical challenge. Management of the primary rectal cancer and prophylactic removal of the colon should be considered. In patients requiring a mesorectal excision, a combined prophylactic colon removal can be considered. Although surveillance of the colon with frequent colonoscopies is an alternative, concerns of metachronous colon cancer development support prophylactic removal of the colon as an alternative. Since data are not available to confirm superiority of either approach, the final decision is greatly dependent upon a patient's wishes and preferences. Patients interested in pursuing simultaneous prophylactic colon removal can be offered total proctocolectomy with either ileal pouch anal-anastomosis as a sphincter-preserving alternative or a total proctocolectomy with end ileostomy.

Ileal pouch-anal anastomosis: Points of controversy

Restorative proctocolectomy with ileal pouch-anal anastomosis has become the most commonly used procedure for elective treatment of patients with ulcerative colitis and familial adenomatous polyposis. Since its original description, the procedure has been modified in order to obtain optimal functional results with low morbidity and mortality, and yet provide a cure for the disease. In this review of the literature of restorative proctocolectomy with ileal pouch-anal anastomosis, we discuss these technical modifications, limiting our discussion to the current points of controversy. The current "hot topics" for debate are: indications for ileal pouch-anal or ileo-rectal anastomosis, indications for pouch surgery in the elderly, indeterminate colitis and Crohn's disease, the place of the laparoscopic approach, transanal mucosectomy with hand-sewn anastomosis vs. the double-stapled technique, the use of diverting ileostomy and the issue of the best route for delivery of pregnant women. Longer follow-up of patients and increased knowledge and experience with pouch surgery, coupled with ongoing prospective evaluation of the procedure are required to settle these issues.

Systematic review with meta-analysis: inflammatory bowel disease in the elderly

BACKGROUND

Elderly patients represent an increasing proportion of the inflammatory bowel disease (IBD) population.

AIM

To critically review available data regarding the care of elderly IBD patients.

METHODS

Bibliographic searches (MEDLINE) up to June 2013.

RESULTS

Approximately 10-15% of cases of IBD are diagnosed in patients aged >60 years, and 10-30% of the IBD population are aged >60 years. In the elderly, IBD is easily confused with other more common diseases, mainly diverticular disease and ischaemic colitis. The clinical features of IBD in older patients are generally similar to those in younger patients. Crohn's disease (CD) in elderly patients is characterised by its predominantly colonic localisation and uncomplicated course. Proctitis and left-sided ulcerative colitis are more common in patients aged >60 years. Infections are associated with age and account for significant mortality in IBD patients. The treatment of IBD in the elderly is generally similar. However, the therapeutic approach in the elderly should be 'start low-go slow'. The benefit of thiopurines in older CD patients remains debatable. Although the indications for anti-tumour necrosis factors in the elderly are generally similar to those for younger patients, lower response and higher adverse events have been reported in the elderly. Surgery in elderly patients does not generally differ. Ileal pouch-anal anastomosis can be successful, provided the patient retains good anal sphincter function.

CONCLUSIONS

Management of the older IBD patient differs from that of younger patients; therefore, conventional practice algorithms may have to be modified to account for advanced age.

The surgical treatment of inflammatory bowel disease-associated dysplasia

Surgical management of colonic dysplasia discovered in the inflammatory bowel disease patient is controversial. Total proctocolectomy (TPC) is the most definitive treatment for the eradication of undiagnosed synchronous dysplasias and/or carcinomas and the prevention of subsequent metachronous lesions in both Crohn's disease (CD) and ulcerative colitis (UC). However, TPC is not always an attractive option owing to patient comorbidities and patient preference. Historically, dysplasia has been most studied in patients with UC, where the option of reconstruction without a stoma makes TPC more acceptable. Due to a relative lack of research on CD-related dysplasia, surveillance and treatment of CD dysplasia has followed paradigms based on UC data. However, due to pathophysiological differences in CD versus UC, options for surgical management in CD may be more varied than simple TPC, particularly in the less healthy surgical candidate and those who refuse end ileostomy.

What we know now: pouch surgery 40 years on

For many patients, ileal pouch-anal anastomosis (also called ileo-anal pouch surgery) not only eradicates disease but also preserves the anal sphincter, enabling the patient to defecate in the normal way. Pouch surgery is approaching 40 years and within this time has become the 'gold standard' in surgical management for ulcerative colitis and familial adeomatous polyposis. Much of the research over the years has explored surgical techniques and pouch function, failure and satisfaction, as well as long-term follow-up; however, some pouch problems continue to be a mystery. This short article aims to bring us up to date with what we know now that might have been beneficial to know then.

Update of complications and functional outcome of the ileo-pouch anal anastomosis: overview of evidence and meta-analysis of 96 observational studies

OBJECTIVE

The objective of this study is to provide a comprehensive update of the outcome of the ileo-pouch anal anastomosis (IPAA).

DATA SOURCES

An extensive search in PubMed, EMBASE, and The Cochrane Library was conducted.

STUDY SELECTION AND DATA EXTRACTION

All studies published after 2000 reporting on complications or functional outcome after a primary open IPAA procedure for UC or FAP were selected. Study characteristics, functional outcome, and complications were extracted.

DATA SYNTHESIS

A review with similar methodology conducted 10 years earlier was used to evaluate developments in outcome over time. Pooled estimates were compared using a random-effects logistic meta-analyzing technique. Analyses focusing on the effect of time of study conductance, centralization, and variation in surgical techniques were performed.

RESULTS

Fifty-three studies including 14,966 patients were included. Pooled rates of pouch failure and pelvic sepsis were 4.3% (95% CI, 3.5-6.3) and 7.5% (95% CI 6.1-9.1), respectively. Compared to studies published before 2000, a reduction of 2.5% was observed in the pouch failure rate (p = 0.0038). Analysis on the effect of the time of study conductance confirmed a decline in pouch failure. Functional outcome remained stable over time, with a 24-h defecation frequency of 5.9 (95% CI, 5.0-6.9). Technical surgery aspects did not have an important effect on outcome.

CONCLUSION
