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 ...
They described the total removal of the colon and rectum with restoration of intestinal continuity by means of an ileo-anal anastomosis without any formation of an ileal pouch or reservoir. They procedure resulted in high frequency and urgency of defaecation day and night which made life difficult for many patients.
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 ...
[1] [11] If the rectum is also removed, it is a total proctocolectomy. Sir William Arbuthnot-Lane was one of the early proponents of the usefulness of total colectomies and was considered a pioneer of colon surgery for routinely performing this procedure. However, his overuse of the procedure called the wisdom of the surgery into question.
This is a two- or three-step procedure. In a three-step procedure, the first surgery is a sub-total colectomy, in which the large bowel is removed, but the rectum remains in situ, and a temporary ileostomy is made. The second step is a proctectomy and formation of the ileal pouch (commonly known as a "j-pouch"). This involves removing the large ...
People with ileostomies typically use an open-ended (referred to as a "drainable") one- or two-piece pouch that is secured at the lower end with a leakproof clip, or velcro fastener. The alternative is the closed-end pouch that must be thrown away when full. Ordinarily, the pouch must be emptied five to eight times a day.
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.
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.
