diverticulitis /dī′vurtik′yo͝olī″tis/ [L, diverticulare, to turn aside; Gk, itis, inflammation] , inflammation of one or more diverticula. The penetration of fecal matter through the thin-walled diverticula causes inflammation and abscess formation in the tissues surrounding the colon. With repeated inflammation the lumen of the colon narrows and may become obstructed. Compare diverticulosis. 
OBSERVATIONS: During periods of inflammation the patient experiences crampy pain, particularly over the sigmoid colon; fever; and leukocytosis. Barium enemas and proctoscopy are used to rule out carcinoma of the colon, which exhibits some of the same symptoms. INTERVENTIONS: Conservative treatment includes rest, IV fluids, antibiotics, and abstaining from eating and drinking. In acute cases bowel resection of the affected part greatly reduces mortality and morbidity rates. PATIENT CARE CONSIDERATIONS: A high-fiber diet and the avoidance of red meats can decrease the development of diverticula and inflammation leading to diverticulits.
