Ascending colon resection is indicated for surgical resection of ascending colon cancer, ulcerative colitis, and intestinal obstruction. After resection, the small intestine can be connected to the end of transverse colon, end-side anastomosis, rectum-anal tube, intestinal anastomosis according to the etiology. 1. Colorectal cancer: the resection scope includes the right companion transverse colon and the end section of ileum and the corresponding mesentery, the lymph nodes of group 6 of stomach, ileum and transverse colon with end-to-end or end-to-side anastomosis. 2. Ulcerative colitis: Surgical treatment of ulcerative colitis includes upper and middle rectal resection, transabdominal colectomy, mucosal stripping of the lower rectum, and anastomosis of the ileum with the anal canal through the rectal muscle sheath. 3. Intestinal obstruction: for the obstruction part of the resection is difficult, in order to lift the obstruction, can be separated from the obstruction part of the near and far intestinal tube for short-circuit anastomosis, open the obstruction part. It is also possible to perform enterostomy or intestinal exenteration. If you need to perform resection of the ascending colon, you need to go to a regular medical institution to receive treatment to avoid delaying your condition.
