Right-Sided Diverticulitis Requiring Colectomy: an Evolving Demographic? A Review of Surgical Outcomes from the National Inpatient Sample Database.
There remains a paucity of recent data on right-sided colonic diverticulitis, especially those undergoing colectomy. We sought to describe the clinical features of patients undergoing both a laparoscopic and open surgery for right-sided diverticulitis.



This study is a review of all cases of a right colectomy or ileocecectomy for diverticulitis from the National Inpatient Sample (NIS) from 2006 to 2012. Demographics, comorbidities, and postoperative outcomes were identified for all cases. A comparative analysis of a laparoscopic versus open approach was performed.



We identified 2233 admissions (laparoscopic = 592; open = 1641) in the NIS database. The majority of cases were Caucasian (67 %), with 6 % of NIS cases identified as Asian/Pacific Islander. The overall morbidity and in-hospital mortality rates were 24 and 2.7 %, respectively. The conversion rate from a laparoscopic to open procedure was 34 %. Postoperative complications were greater in the open versus laparoscopic cohorts (25 vs. 19 %, p < 0.01), with pulmonary complications as the highest (7.0 vs. 1.7 %; p < 0.01).



This investigation represents one of the largest cohorts of colon resections to treat right-sided diverticulitis in the USA. In this series, right-sided diverticulitis undergoing surgery occurred most commonly in the Caucasian population and is most often approached via an open surgical technique; however, laparoscopy is a safe and feasible option.
