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.
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 ...
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. A surgical anastomosis can be created using suture sewn by hand, mechanical staplers and biological glues , depending on the circumstances.
Total mesorectal excision (TME) is a standard surgical technique for treatment of rectal cancer, first described in 1982 by Professor Bill Heald at the UK's Basingstoke District Hospital. [ 1 ] [ 2 ] It is a precise dissection of the mesorectal envelope comprising rectum containing the tumour together with all the surrounding fatty tissue and ...
Vein skeleton of a Hydrangea leaf showing anastomoses of veins. An anastomosis (/ ə ˌ n æ s t ə ˈ m oʊ s ɪ s /, pl.: anastomoses) is a connection or opening between two things (especially cavities or passages) that are normally diverging or branching, such as between blood vessels, leaf veins, or streams.
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.
After the mesenteric vessels are dissected, the colon is divided with special surgical staplers that close off the bowel while cutting between the staple lines. After resection of the affected bowel segment, an anvil and spike are used to anastomose the remaining segments of the bowel.
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.
