Before removal, the portion of the bowel to be resected must be freed or mobilized. This is done by dissection and removal of the mesentery and other peritoneal attachments. Resection of any part of the colon entails mobilization and the cutting and sealing, or ligation, of the blood vessels supplying the portion of the colon to be removed. [8]

The right and left colon sit in the retroperitoneum. To access this space an incision is made along the line of Toldt. 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.
Proctocolectomy is the surgical removal of the entire colon and rectum from the human body, leaving the patients small intestine disconnected from their anus. [1] It is a major surgery that is performed by colorectal surgeons, however some portions of the surgery, specifically the colectomy (removal of the colon) may be performed by general surgeons. [2]

The stools gradually solidify as they move along into the descending ...
Gross pathology of a tubulovillous adenoma resected by minimally invasive colorectal surgery.. Surgical forms of treatment for these conditions include: colectomy, ileo/colostomy, polypectomy, strictureplasty, hemorrhoidectomy (in severe cases of hemorrhoids), minimally invasive surgery, anoplasty, and more depending on the condition the patient has.
Treatment consists of intravenous fluids, antibiotics, and avoiding oral intake of food, water, etc. until symptoms improve. Risk factors include right colon polypectomy, large polyp size (>2 cm), non-polypoid lesions (laterally spreading lesions), and hypertension. [47] Although rare, infections of the colon are a potential colonoscopy risk.
There are several surgical options that involve the removal of either the colon or both the colon and rectum. Rectum involved: the rectum and part or all of the colon are removed.
