How to manage diverticular stenosis in 2026?—an updated clinical practice review
Year: 2026
Type: article
Abstract: Diverticular stenosis and diverticulitis correspond to a fibrous narrowing of the colon secondary to chronic inflammation of diverticular origin. Its prevalence is rare, accounting for less than 1% of patients with sigmoid diverticulitis. Although surgery is usually recommended in symptomatic patients, the main issue remains the etiology of this stenosis. This updated clinical practice review aims to clarify the appropriate management of diverticular stenosis and to describe advantages and disadvantages of their management options. A clinical practice review was performed focusing on management of diverticular stenosis in both emergency and elective situations. Relevant clinical studies were analyzed, whether in diagnostic or therapeutic approaches. Very few studies have been published in the literature regarding the management of diverticular stricture. The primary objective, both in emergency and elective settings, is to rule out colorectal cancer. To this end, contrast-enhanced abdominal and pelvic computed tomography (CT) scans, colonoscopy, and even CT colonography are available. In emergency situations, a colostomy without resection allows for further investigation at a later date, as endoscopic stenting is not recommended. In elective situations, colorectal resection with anastomosis is recommended in symptomatic patients. In summary, diverticular stenosis, a complicated form of chronic diverticulitis, still represents a diagnostic and strategic challenge today.
