The total removal of the colon, called a colectomy or resection of affected parts of the colon may be needed if part of the gut dies (for instance toxic megacolon), or if there is a localized area of dysmotility. Gastric and colonic pacemakers have been tried. These are strips placed along the colon or stomach which create an electric discharge ...
Colectomy (col-+ -ectomy) is the surgical removal of any extent of the colon, the longest portion of the large bowel. Colectomy may be performed for prophylactic, curative, or palliative reasons. Colectomy may be performed for prophylactic, curative, or palliative reasons.
Distal intestinal obstruction syndrome Small intestine(at center) DIOS was previously known as meconium ileus equivalent , a name which highlights its similarity to the intestinal obstruction seen in newborn infants with cystic fibrosis. [ 2 ]
The signs and symptoms of colorectal cancer depend on the location of the tumor in the bowel, and whether it has spread elsewhere in the body ().The classic warning signs include: worsening constipation, blood in the stool, decrease in stool caliber (thickness), loss of appetite, loss of weight, and nausea or vomiting in someone over 50 years old.

Only the proximal stoma is functioning. Most often, double-barrel colostomy is a temporary colostomy with two openings into the colon (distal and proximal). The elimination occurs through the proximal stoma. Colostomy surgery that is planned usually has a higher rate of long-term success than surgery performed in an emergency situation.
Azoxymethane (AOM) is a genotoxic colonic carcinogen and is routinely used to induce colon tumours in mice. [30] The AOM-induced tumours form in the last three centimeters of the distal colon but a p21 knock out mouse treated with AOM shows tumour distribution throughout the colon. [31]
The colon cut-off sign is a radiographic finding seen on abdominal radiographs and computed tomography scans. It is characterized by a marked dilatation of the transverse colon, with an abrupt transition to collapsed distal colon, particularly the splenic flexure. [1] This sign is indicative of underlying pathology, most commonly acute ...
William Ernest Miles (1869–1947), an English surgeon first performed the surgery of removing the rectum in 1907. He assumed that the rectal cancer can spread in both upwards and downward directions, thus necessitating the removal of the entire rectum together with the anal sphincters, resulting in a permanent stoma by connecting the proximal end of the descending colon to the skin.
