Transanal Ileal Pouch-Anal Anastomosis for Ulcerative Colitis has Comparable Long-Term Functional Outcomes to...

Area of Science:

• Colorectal Surgery
• Gastroenterology
• Surgical Outcomes

Background:

• Ulcerative colitis (UC) treatment often involves ileal pouch-anal anastomosis (IPAA).
• The transanal approach to IPAA (Ta-IPAA) may offer advantages in pelvic access and reduced short-term morbidity compared to the transabdominal approach (Abd-IPAA).

Purpose of the Study:

• To compare the long-term functional outcomes and quality of life between Ta-IPAA and Abd-IPAA in patients with UC.
• To evaluate the Cleveland Global Quality of Life (CGQL) score as a primary endpoint.

Main Methods:

• A multicenter cohort analysis was conducted from March 2002 to September 2017.
• Patient characteristics, surgical details, and postoperative outcomes were compared between Ta-IPAA and Abd-IPAA groups.
• The primary endpoint was the CGQL score at 12 months post-surgery in patients with a functioning pouch.

Main Results:

• A total of 374 patients (100 Ta-IPAA, 274 Abd-IPAA) were analyzed.
• Overall quality of life (CGQL score) was comparable between Ta-IPAA and Abd-IPAA (p=0.1).
• Specific quality of life (p=0.04) and energy-level items (p=0.03) were significantly better after Ta-IPAA. Stool frequency and incontinence rates were similar between groups. Short-term morbidity and anastomotic leak rates did not differ significantly.

Conclusions:

• Ta-IPAA demonstrates comparable long-term functional outcomes and quality of life to Abd-IPAA for ulcerative colitis.
• The transanal approach is a viable alternative for IPAA in UC patients, offering similar long-term results.
• Further research may explore the specific benefits of Ta-IPAA regarding short-term morbidity.
