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.
William Ernest Miles (1869–1947), an English surgeon first performed the surgery of removing the rectum in 1907. He assumed that the rectal cancer can spread in both upwards and downward directions, thus necessitating the removal of the entire rectum together with the anal sphincters, resulting in a permanent stoma by connecting the proximal end of the descending colon to the skin.
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.
Resection of any part of the colon entails mobilization and the cutting and sealing, or ligation, of the blood vessels supplying the portion of the colon to be removed. [8] A stapler is typically used to cut across the colon to prevent spillage of intestinal contents into the peritoneal cavity. [10]
Colorectal surgery is a field in medicine dealing with disorders of the rectum, anus, and colon. [1] The field is also known as proctology , but this term is now used infrequently within medicine and is most often employed to identify practices relating to the anus and rectum in particular.
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 colon is then mobilized from the retroperitoneum. Care is taken to avoid injury to the ureters and duodenum. The surgery then follows the same steps as small bowel resection. However, due to the colon's placement in the retroperitoneum, more dissection is often required to allow for tension free anastomosis. [5] [6]
The original pull-through procedure was designed by Orvar Swenson and his colleague Alexander Bill. The abnormal aganglionic part of the bowel is resected down to the sigmoid colon and rectum, and the normal colon and the low rectum are subsequently joined.
