Right-side diverticulitis (RSD) is an uncommon disease in Western countries. We conducted a case-matched comparison of surgically managed right-side and left-side diverticulitis (LSD) from the Southern California Kaiser Permanente database (2007-2014). Of 995 patients undergoing emergent surgery for diverticulitis, 33 RSD (3.3%) met our inclusion criteria and were matched (1:1) to LSD based on age, gender, year of diagnosis, and Hinchey class. Mean age of the RSD group was 56 6 13.9 years, and 24.2 per cent were Asian. RSD was classified as Hinchey class III or IV in 28.1 per cent and 9.4 per cent of cases, respectively. Right hemicolectomy was performed in 87.9 per cent and laparoscopy was used in 24.2 per cent of the cases. Surgically managed RSD patients were more likely to be Asian (25% vs 3.1%, P 5 0.03) and have body mass index < 25 (31.3% vs 6.3%, P 5 0.02) compared with LSD patients. Diverting stoma was less common in the RSD (6.3% vs 62.5%) (P < 0.001). Hospital stay was shorter in RSD (7.6 6 4.2 vs 12.8 6 9.4 days, P 5 0.006) and more common in the RSD group (P < 0.01). Open surgery (90.6% vs 71.9%) and postoperative complications (37.5% vs 25%) were more common in the LSD group, but that was not statistically significant (P > 0.05). Surgery for complicated RSD was associated with shorter hospital stay and decreased likelihood of diverting ostomy.
