Placement of the stoma on the abdomen can occur at any location along the colon, but the most common placement is on the lower left side near the sigmoid where a majority of colon cancers occur. Other locations include the ascending , transverse , and descending sections of the colon.
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. It was used to treat colon cancer or inflammation (proctosigmoiditis, proctitis, diverticulitis, volvulus, etc.).
A single-use rotatable endoclip in packaging. An endoclip is a metallic mechanical device used in endoscopy in order to close two mucosal surfaces without the need for surgery and suturing.
A large volume enema [12] to inject liquid into the colon either to cleanse feces from as much of the colon as possible [13] or to deliver a drug solution. A specialized catheter designed for rectal administration of medications and liquids, that can be placed safely and remain comfortably in the rectum for repeated use.
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 colon (progressing from the ascending colon to the transverse, the descending and finally the sigmoid colon) is the longest portion of the large intestine, and the terms "large intestine" and "colon" are often used interchangeably, but most sources define the large intestine as the combination of the cecum, colon, rectum, and anal canal.
[2] [18] In an isolated intestinal transplant, the colon will be detached from the small intestine. The cecum and ascending colon are devascularized, while care is taken to preserve major vasculature in the ileum. The jejunum will be separated from the duodenum while preserving the vasculature of the jejunum, ileum, mesentery, and the pancreas.
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.
