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 ...
An anastomotic leak is a fault in the surgical connection between the two remaining sections of bowel after a resection is performed. This allows the bowel contents to leak into the abdomen. Anastomotic leaks may cause infection, abscess development, and organ failure if untreated. Surgical steps are taken to prevent leaks when possible.
Diagrammatically, the Roux-en-Y anastomosis looks a little like the letter Y. [ citation needed ] Typically, the two upper limbs of the Y represent (1) the proximal segment of stomach and the distal small bowel it joins with and (2) the blind end that is surgically divided off, and the lower part of the Y is formed by the distal small bowel ...
An anastomosis carries the risk of dehiscence or breakdown of the surgical connection. Contamination of the peritoneal cavity with fecal matter as a result of the anastomotic leak can lead to peritonitis, sepsis or death. In patients who underwent colectomy as a treatment for colorectal cancer, an anastomotic leak increases the risk of ...
Symptoms include abdominal pain which may come and go, vomiting, abdominal bloating, and bloody stool. [1] It often results in a small bowel obstruction. [1] Other complications may include peritonitis or bowel perforation. [1] The cause in children is typically unknown; in adults a lead point is sometimes present. [1]
The signs and symptoms are variable, and in up to 25% of patients there may be no symptoms. [3] The most common signs and symptoms are bleeding, which can vary from minor to severe, rectal prolapse and incomplete evacuation (35%-76% of cases). [4]
Anorectal varices are collateral submucosal blood vessels dilated by backflow in the veins of the rectum. [1] Typically this occurs due to portal hypertension which shunts venous blood from the portal system through the portosystemic anastomosis present at this site into the systemic venous system.
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 .
