mucosectomy
Pronunciation: mew-ko-SEK-toh-mee
Surgical removal of intestinal mucosa while preserving underlying muscular layers, used in specific reconstructive procedures.
Full Definition
Mucosectomy is a specialized surgical technique involving the precise removal of the intestinal mucosal layer while preserving the underlying submucosa and muscular layers. This procedure is commonly employed in ileal pouch-anal anastomosis construction, where rectal mucosa is stripped from the anal canal to allow pouch advancement while maintaining sphincter function. The technique requires careful dissection to avoid perforation of the muscular wall and to ensure complete mucosal removal. Mucosectomy is also used in endoscopic procedures for removing large polyps or early malignancies.
Usage
Usage note: Specify approach (transanal, endoscopic) when documenting procedure.
