Effects of age at disease onset and at treatment on serology in inflammatory bowel diseases

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.

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.
