Severe diffuse abdominal pain, fever, tachycardia, leukocytosis or other signs of sepsis and diffuse peritonitis indicative of free perforation requires emergent surgery. Urgent surgery should be considered when your patient fails to improve (eg, abdominal pain or the inability to tolerate enteral nutrition, bowel obstruction, or infection-related ileus) despite medical therapy or percutaneous drainage. 1,2
Lower threshold for surgical intervention is also needed in transplant patients, patients on chronic corticosteroid therapy, other immunosuppressed patients and those with chronic renal failure or collagen-vascular disease because these patients have a significantly greater risk of recurrent, complicated diverticulitis requiring emergency surgery. Overall, up to 20% of patients with acute diverticulitis undergo surgery during the same hospitalization.2
For patients with recurrent uncomplicated diverticulitis, decision regarding future elective surgery should be individualized. Although older guidelines recommended surgery after 2 attacks of uncomplicated diverticulitis, more recent guidelines place less emphasis on the number of episodes and stress the importance of considering the severity of the attacks, chronic or lingering symptoms, inability to exclude carcinoma, overall medical condition of the patient, risks of surgery, and the impact of diverticulitis on the patient’s lifestyle.1,2
Of interest, a decision analysis model suggests that elective resection after a fourth episode may be as safe as earlier resection.3
