  2. Ventral rectopexy - Wikipedia

    en.wikipedia.org/wiki/Ventral_rectopexy

    In men, mobilization of the rectum may risk the development of erectile dysfunction. [9] Another way of categorizing surgery for prolapse of pelvic organs is suspensive or resective (involving removal of sections of the bowel wall). Ventral rectopexy alone is a syspensive type surgery, a category which also includes colposacropexy. [10]

  3. Hartmann's operation - Wikipedia

    en.wikipedia.org/wiki/Hartmann's_operation

    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.).

  4. Colectomy - Wikipedia

    en.wikipedia.org/wiki/Colectomy

    Stapler anastomosis of sigmoid colon In modern times, surgical staplers are typically used to create colorectal anastomoses, although hand sewn, or sutured , anastomoses are still done today. Studies have shown that differences in rates of anastomotic leak and surgical site contamination for stapled vs. sutured anastomoses are not statistically ...

  5. Bowel resection - Wikipedia

    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]

  6. Surgical anastomosis - Wikipedia

    en.wikipedia.org/wiki/Surgical_anastomosis

    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 .

  7. Inferior mesenteric artery - Wikipedia

    en.wikipedia.org/wiki/Inferior_mesenteric_artery

    In human anatomy, the inferior mesenteric artery (IMA) is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal. The regions supplied by the IMA are the descending colon, the sigmoid colon, and part of the rectum. [1]

  8. Colostomy - Wikipedia

    en.wikipedia.org/wiki/Colostomy

    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 ...

  9. Superior rectal artery - Wikipedia

    It descends into the pelvis between the layers of the mesentery of the sigmoid colon, crossing the left common iliac artery and vein. It divides, opposite the third sacral vertebra into two branches, which descend one on either side of the rectum. About 10 or 12 cm from the anus, these branches break up into several small branches.
