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

PURPOSE: 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.

METHODS: 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.

RESULTS: 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.

CONCLUSION: 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.
