Possible overuse of 3-stage procedures for active ulcerative colitis

Area of Science:

• Gastroenterology
• Surgical Oncology
• Inflammatory Bowel Disease Research

Background:

• The assumption that 3-stage procedures for ulcerative colitis are safer than 2-stage procedures lacks robust data.
• Optimal surgical staging for high-risk patients with ulcerative colitis remains unclear, particularly regarding anastomotic leak.
• This study investigates the validity of the 3-stage approach assumption and its impact on surgical outcomes.

Purpose of the Study:

• To identify factors influencing the choice between 2-stage and 3-stage ileal pouch-anal anastomosis (IPAA) procedures for ulcerative colitis.
• To compare surgical outcomes, including complications and long-term results, between 2-stage and 3-stage IPAA.
• To determine the impact of procedure staging on anastomotic leak risk and other postoperative complications.

Main Methods:

• Retrospective analysis of 144 patients with active ulcerative colitis undergoing 2-stage or 3-stage IPAA surgery.
• Data collected over a 10.5-year period at a single academic medical center.
• Analysis of factors influencing procedure choice and comparison of postoperative outcomes, including anastomotic leak, stricture, fistula, abscess, and pouch failure.

Main Results:

• The decision for a 3-stage procedure was influenced by emergent status and hemodynamic instability, not patient demographics or medication use.
• While univariate analysis suggested more complications with 2-stage procedures, multivariate analysis attributed this to surgeon experience, not the procedure itself.
• Importantly, 2-stage IPAA did not increase the risk of anastomotic leak (OR=1.09, P=.94).
• Long-term follow-up revealed a lower risk of anal stricture with 2-stage procedures (OR=8.21, P=.01) without differences in fistula, abscess, or pouch failure.

Conclusions:

• The use of steroids and anti-tumor necrosis factor agents alone does not necessitate avoiding IPAA creation in the first operation.
• A 2-stage IPAA is a safe and effective approach for ulcerative colitis, especially when performed by experienced inflammatory bowel disease surgeons.
• The perceived safety advantage of 3-stage procedures may be overstated, and 2-stage approaches offer comparable or better outcomes regarding specific complications like anal stricture.
