mucosectomy
Pronunciation: myoo-koh-SEK-toh-mee
Surgical removal of mucosa, particularly used in pull-through procedures for anorectal malformations.
Full Definition
Mucosectomy is a surgical technique involving the careful dissection and removal of the mucosal layer of the bowel wall while preserving the underlying muscle layers. In pediatric colorectal surgery, mucosectomy is commonly performed as part of endorectal pull-through procedures, such as the Soave procedure for Hirschsprung disease. The technique allows for preservation of the rectal muscle cuff while removing the aganglionic mucosa. Proper execution of mucosectomy is crucial for optimal functional outcomes and requires precise surgical technique to avoid perforation of the muscle wall.
Usage
Usage note: Distinguish from mucosal biopsy or other mucosal procedures.
