Surgical solutions for refractory J-pouch inlet obstruction.

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Surgical Innovation

Background:

• Total proctectomy with ileal pouch-anal anastomosis is a common treatment for ulcerative colitis.
• J-pouch inlet obstructions can be difficult to manage nonoperatively or endoscopically.
• Historically, refractory obstructions often necessitated pouch resection.

Purpose of the Study:

• To evaluate the feasibility and outcomes of pouch salvage surgery for J-pouch inlet obstructions.
• To assess the long-term functional results and complication rates of these salvage procedures.

Main Methods:

• Retrospective review of patients undergoing pouch salvage for J-pouch inlet obstructions (2000-2017).
• Data collection included demographics, workup, surgical intervention, and outcomes.
• Analysis of different surgical techniques for strictures, angulations, and internal hernias.

Main Results:

• Eight patients with J-pouch inlet obstructions underwent salvage surgery.
• Six patients had strictures/angulations treated by bypass or resection/re-anastomosis.
• Two patients with internal hernias/volvulus were treated; all pouches were retained at mean 36.5 months follow-up.
• Mean daily bowel movements were eight; two major and two minor complications occurred.

Conclusions:

• J-pouch inlet obstructions can develop over time and may become refractory to non-surgical management.
• Pouch salvage surgery offers good functional results for patients with refractory obstructions.
• Awareness of novel surgical techniques is crucial given the increasing number of J-pouches performed.
