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 ...
CT scan showing extensive diverticulosis of the sigmoid colon Diverticular disease Whole slide of a transverse section of the left colon with diverticulosis. Diverticulosis is defined by the presence of multiple pouches (diverticula) in the colon. [22] In people without symptoms, these are usually found incidentally during other investigations.
Bowel obstruction, also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion. [2] [5] Either the small bowel or large bowel may be affected. [1] Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. [1]
Section of the large bowel (sigmoid colon) showing multiple pouches (diverticula). The diverticula appear on either side of the longitudinal muscle bundle (taenium), which runs horizontally across the specimen in an arc. Specialty: General surgery: Symptoms: Abdominal pain, fever, nausea, diarrhea, constipation, blood in the stool [1] Complications
Endoscopic image of severe Crohn's colitis showing diffuse loss of mucosal architecture, friability of mucosa in sigmoid colon and exudate on wall. Specialty: Gastroenterology: Symptoms: Diarrhea, abdominal pain, fatigue, weight loss, fever [1] Complications: Anemia, bowel cancer, bowel obstruction, strictures, fistulas, abscesses, anal fissure ...
In patients with sigmoid volvulus, although abdominal pain may be present, symptoms of constipation may be more prominent. Volvulus causes severe pain and progressive injury to the intestinal wall, with accumulation of gas and fluid in the portion of the bowel obstructed. [ 11 ]
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 ...
Those with severe ischemia who develop complications such as sepsis, intestinal gangrene, or bowel perforation may require more aggressive interventions, such as surgery and intensive care. Most patients make a full recovery; occasionally, after severe ischemia, patients may develop long-term complications such as a stricture [ 49 ] or chronic ...
