Duhamel Operation


Duhamel Operation is performed to treat Hirschsprung’s Disease (a condition in which nerve cells in the intestine don’t develop properly). In this procedure, the ganglionic bowel is pulled down behind the lower aganglionic segment, however, within the puborectalis muscle. The surgeon divides the rectum near the peritoneal reflection, opening the retrorectal space to below the pelvic floor. The surgeon makes an incision in the posterior side of the anal canal at the level of the dentate line to pull through the proximal ganglionic bowel and sutures it to the posterior half of the opening of the anal canal.
