Is surgery necessary to confirm diagnosis of right-sided diverticulitis in spite of relevant clinical and radiological findings?

BACKGROUND: Diverticulosis of the right colon is an uncommon entity. Aim of the present study was to report outcome in patients with right-sided diverticulitis diagnosed using computed tomography (CT) and treated conservatively. METHODS: Twelve patients with clinical and radiological diagnosis of cecal or right-sided diverticulitis who were treated conservatively between February 2013 and December 2014 were included. Demographic and clinical data were retrospectively analyzed. RESULTS: Female to male ratio was 1: 1 with mean age of 45.08 +/- 14.4 years. Mean length of symptom history before admission was 2.08 +/- 1.3 days. Most common presenting symptom was right lower abdominal pain, seen in 72.7% of the patients. Abdominal ultrasound alone was performed for 10 patients, and 2 also had abdominal CT. Mean duration of hospitalization was 2.8 +/- 1.5 days. All patients were successfully treated with medical therapy. There was no recurrence during mean follow-up period of 8.2 +/- 5.6 months. CONCLUSION: If uncomplicated diverticulitis of the right colon is correctly diagnosed with radiological evaluation, antibiotic therapy and bowel rest should be considered as treatment modality, as there was no recurrence observed in short-term follow-up period and this option presents advantage of avoiding surgical intervention.
