Eversion technique for distal mucosal proctectomy in ulcerative colitis: a preliminary report

Area of Science:

• Colorectal Surgery
• Gastroenterology
• Surgical Innovation

Background:

• Ulcerative colitis requires surgical intervention, often involving rectal mucosectomy.
• Traditional endocavitary techniques for rectal mucosectomy can be challenging.
• Improved surgical methods are needed to enhance outcomes in ulcerative colitis treatment.

Purpose of the Study:

• To describe and evaluate a new peranal eversion technique for distal rectal mucosal proctectomy.
• To assess the ease, accuracy, and expedition of this novel surgical approach.
• To compare functional results with the established endocavitary technique in patients undergoing ileo-anal anastomosis.

Main Methods:

• A peranal eversion technique was developed to facilitate distal rectal mucosal proctectomy.
• The procedure was performed as part of an ileo-anal anastomosis with a pelvic ileal reservoir.
• Functional outcomes were assessed in patients who underwent this technique and compared to those who had an endocavitary mucosectomy.

Main Results:

• The peranal eversion technique demonstrated impressive ease, accuracy, and expedition in mucosal excision.
• In 9 of 16 patients, functional results using the peranal eversion method were similar to 14 patients who had the endocavitary technique.
• The novel technique appears to yield comparable functional outcomes to the standard procedure.

Conclusions:

• Peranal eversion of the lower rectum is a viable and effective technique for distal mucosal proctectomy in ulcerative colitis.
• This method offers potential advantages in terms of surgical performance and patient outcomes.
• Further research may validate this technique as an alternative to endocavitary mucosectomy for ileo-anal anastomosis.
