Instead of the dissection via the abdomen TaTME combines an abdominal and transanal endoscopic approach ...
Rectopexy is a surgery for rectal prolapse. [3] A newer version of the procedure is termed ventral mesh rectopexy, which has also been used for SRUS. [14] It may be performed with or without anterior resection (removal of a portion of the front wall of the rectum). [9] A mesh may be used to reinforce the anterior rectal wall. [8]
The mesh is placed directly onto the anterior (ventral) surface of the rectum. [1] This procedure aims to suspend the middle and lower sections of the rectum. This modified procedure is now known as the anterior rectopexy or ventral rectopexy. [1] D'Hoore also used a laparoscopic approach (laparoscopic ventral mesh rectopexy, LVMR). [15]
A proctosigmoidectomy, Hartmann's operation or Hartmann's procedure is the surgical resection of the rectosigmoid colon with closure of the anorectal stump and formation of an end colostomy. It was used to treat colon cancer or inflammation (proctosigmoiditis, proctitis, diverticulitis, volvulus, etc.).
Lateral internal sphincterotomy is the preferred method of surgery for persons with chronic anal fissures, and is generally used when medical therapy has failed. [1] It is associated with a lower rate of side effects than older techniques such as posterior internal sphincterotomy and anoplasty, [3] and has also been shown to be superior to topical glyceryl trinitrate (GTN 0.2% ointment) in ...
