Colectomy (col-+ -ectomy) is the surgical removal of any extent of the colon, the longest portion of the large bowel. Colectomy may be performed for prophylactic, curative, or palliative reasons. Indications include cancer, infection, infarction, perforation, and impaired function of the colon.
Then bowel is then dissected away from the mesentery. Following this the remaining bowel is observed to verify continued blood flow. After resection the surgeon will create an anastomosis between the two ends of the bowel. Following this the hole in the mesentery created by removing the section of bowel is closed with sutures to prevent ...
Currently, its use is limited to emergency surgery when immediate anastomosis is not possible, or more rarely it is used palliatively in patients with colorectal tumours. [ 1 ] The Hartmann's procedure with a proximal end colostomy or ileostomy is the most common operation carried out by general surgeons for management of malignant obstruction ...
In medicine, the ileal pouch–anal anastomosis (IPAA), also known as restorative proctocolectomy (RPC), ileal-anal reservoir (IAR), an ileo-anal pouch, ileal-anal pullthrough, or sometimes referred to as a J-pouch, S-pouch, W-pouch, or a pelvic pouch, is an anastomosis of a reservoir pouch made from ileum (small intestine) to the anus, bypassing the former site of the colon in cases where the ...
A surgical anastomosis is a surgical technique used to make a new connection between two body structures that carry fluid, such as blood vessels or bowel. For example, an arterial anastomosis is used in vascular bypass and a colonic anastomosis is used to restore colonic continuity after the resection of colon cancer .
Proctocolectomy is the surgical removal of the entire colon and rectum from the human body, leaving the patients small intestine disconnected from their anus. [1] It is a major surgery that is performed by colorectal surgeons, however some portions of the surgery, specifically the colectomy (removal of the colon) may be performed by general surgeons. [2]
Colostomy or ileostomy is now rarely performed for rectal cancer, with surgeons usually preferring primary resection and internal anastomosis, [3] e.g. an ileo-anal pouch. In place of an external appliance , an internal ileo-anal pouch is constructed using a portion of the patient's lower intestine, to act as a new rectum to replace the removed ...
Coloanal anastomosis (also known as coloanal pull-through) is a surgical procedure in which the colon is attached to the anus after the rectum has been removed.
