A colonic stricture is a band of scar tissue which forms as a result of the ischemic injury and narrows the lumen of the colon. Strictures are often treated observantly; they may heal spontaneously over 12–24 months.
Sigmoid volvulus is the most-common form of volvulus of the gastrointestinal tract. [13] and is responsible for 8% of all intestinal obstructions. [citation needed] Sigmoid volvulus is particularly common in elderly persons and constipated patients. Patients experience abdominal pain, distension, and absolute constipation.
Sigmoid colon volvulus, also known as sigmoid volvulus, is volvulus affecting the sigmoid colon. It is a common cause of bowel obstruction [ 1 ] and constipation . It is common in Asia, India (7% of intestinal obstruction ) and especially South India because of the high fibre diet.
The sigmoid colon is completely surrounded by peritoneum (and thus is not retroperitoneal), which forms a mesentery (sigmoid mesocolon), which diminishes in length from the center toward the ends of the loop, where it disappears, so that the loop is fixed at its junctions with the iliac colon and rectum, but enjoys a considerable range of movement in its central portion.
The descending colon, medial deviation of the cecum, and "the whirl sign," which is produced by the twisted intestinal tract and sigmoid mesocolon in ileosigmoid knot, are findings in a CT scan that are suggestive of ileosigmoid knotting. Furthermore, some have observed the radial distribution of the mesenteric vasculature and the intestine and ...
During surgery anatomic defects in the sigmoid colon are sometimes observed in patients with ODS, such as acute bends which are stuck laterally (to one side of) or in front of the rectum. Many such defects may arise after hysterectomy because surgical adhesions in the pelvis may occur with scarring after the surgery.

Specialty: Gastroenterology: Symptoms: Diarrhea, abdominal pain, fatigue, weight loss, fever [1] Complications: Anemia, bowel cancer, bowel obstruction, strictures, fistulas, abscesses, anal fissure ...
Fecal calprotectin, a marker of colon inflammation, may be elevated. Computed tomography of the abdomen is not routinely necessary, but may show thickening or inflammation in the distal colon (sigmoid colon) with associated diverticulosis. Treatment may consist of antibiotics, aminosalicylates (mesalamine), or prednisone. In rare cases, surgery ...
