Pouch Function Over Time and With Advancing Age.

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Inflammatory Bowel Disease (IBD) Management

Background:

• Limited long-term data exists for ileal pouch-anal anastomosis (IPAA) function beyond 30 years or in patients over 80.
• Previous studies have not comprehensively analyzed pouch function and failure rates in these specific patient cohorts.

Purpose of the Study:

• To investigate pouch function and pouch failure rates in patients with an IPAA in situ for over 30 years.
• To evaluate pouch outcomes in patients aged 80 years and older who have undergone IPAA.

Main Methods:

• Retrospective review of adult ulcerative colitis patients who underwent IPAA between 1983 and 1990.
• Data collection included diagnosis, age at IPAA, surgical approach, postoperative outcomes, and long-term functional data retrieved via survey in April 2020.

Main Results:

• Of 145 patients with IPAA in situ for ≥30 years or aged ≥80 years, 75 had pouches ≥30 years and 14 were ≥80 years old.
• Patients ≥80 years experienced significantly higher rates of urgency (71.5%) and daytime seepage (71.4%).
• Nearly 50% of patients ≥80 years with pouches ≥30 years reported occasional urgency/incontinence; one-third experienced pouch failure. Overall pouch failure rate was 19.4% (n=110) at median 15-year follow-up, with risk factors including female sex, 3-stage approach, and pelvic sepsis.

Conclusions:

• IPAA patients demonstrate sustained pouch function even after 30 years and into advanced age (≥80 years).
• Pouch function naturally declines over extended periods, correlating with increased rates of pouch failure.
• These findings support the long-term viability of IPAA in select patient populations, while highlighting the need for ongoing monitoring.
