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 ...
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
Segmental colitis associated with diverticulosis (SCAD) is a condition characterized by localized inflammation of the colon between diverticula (interdiverticular mucosa) while sparing the diverticular orifices. SCAD may lead to abdominal pain, especially in the left lower quadrant, intermittent rectal bleeding, and chronic diarrhea.
Diverticulitis occurs when small pouches in the wall of your colon, called diverticula, get inflamed or infected, Dr. Boxer explains. “It usually causes pain on the lower left side of your belly ...

It is thought to be multi-factorial, including colonic ischemia secondary to old age and other cardiovascular risk factors, diverticulosis causing mucosal prolapse, fecal stasis and subsequent microbiome disturbance, eventually leading to ...
Ischemic colitis must be differentiated from the many other causes of abdominal pain and rectal bleeding (for example, infection, inflammatory bowel disease, diverticulosis, or colon cancer). It is also important to differentiate ischemic colitis, which often resolves on its own, from the more immediately life-threatening condition of acute ...
