A lower anterior resection, formally known as anterior resection of the rectum and colon and anterior excision of the rectum or simply anterior resection (less precise), is a common surgery for rectal cancer and occasionally is performed to remove a diseased or ruptured portion of the intestine in cases of diverticulitis.
Low anterior resection syndrome is a complication of lower anterior resection, a type of surgery performed to remove the rectum, typically for rectal cancer.It is characterized by changes to bowel function that affect quality of life, and includes symptoms such as fecal incontinence, incomplete defecation or the sensation of incomplete defecation (rectal tenesmus), changes in stool frequency ...
The symptoms collectively are referred to as low anterior resection syndrome (LARS) and adversely affect quality of life, sometimes so much so that some patients even prefer to have their stoma-reversal itself reversed, and to live with a permanent colonostomy or iliostomy. [11]
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.).
To reduce the incidence of death and suffering of the patients associated with the APR procedure, Henri Albert Hartmann introduced the anterior resection of the rectum by preserving the distal rectum and anal sphincters, while producing end-sigmoid colostomy. There were attempts to restore bowel continuity by joining the proximal colon with the ...
A resection margin or surgical margin is the margin of apparently non-tumorous tissue around a tumor that has been surgically removed, called "resected", in surgical oncology. The resection is an attempt to remove a cancer tumor so that no portion of the malignant growth extends past the edges or margin of the removed tumor and surrounding tissue.
The size of the ulcers is usually 0.5–4 cm. [5] The lesion is most often located on the anterior (front) or lateral (side) rectal wall, centered on a rectal fold, [1] usually 10 cm from the anal verge. [8] Less commonly there may be ulcers in the anal canal or even in the sigmoid colon. [5]
