Right-sided acute diverticulitis in a North African country: Presentation and management in one surgical center

Right-sided diverticulitis is a rare entity in North Africa. Therefore, it is usually misdiagnosed, and the management of cecal diverticulitis is aggressive in most cases, whereas nowadays, most studies recommend a conservative approach with promising results. This study aims to describe the presentation, management, and outcomes of right-sided diverticulitis (RSD) and to present the experience of one surgical center in Tunisia.

This is a retrospective study including all patients presented with RSD, in the Department of Surgery "A" of the Charles Nicolle Hospital between 2007 and 2021.

Forty patients were included in our study. The mean age was 42 years with a standard deviation of 14. The sex ratio was 1.1. Only 2 patients had chronic constipation. All patients presented right-sided abdominal pain, and only 3 patients had diarrhea. Twenty one patients were diagnosed during surgery. Fourteen patients were treated successfully by conservative management. An operative procedure was performed in 26 cases: 21 had a diverticulectomy (80%), two had an ileal resection (8%), and three had a right colectomy (11.5%). No postoperative events occurred with a short hospital stay (5 ± 3 days). Follow-up showed no recurrences.

Right-sided diverticulitis has a lower incidence and complication rate compared to left-sided diverticulitis. Conservative treatment has demonstrated favorable outcomes in managing RSD, although the available evidence remains limited.
