Surgery for diverticulitis: a re-evaluation of the changing trends.

The surgical management of diverticulitis continues to evolve but recent literature has not qualified just how different current practice is compared with the previous era. This study aims to update the seminal paper by Rodkey and Welch regarding indications and operation types performed for diverticulitis by comparing their findings with present practice at a community based institution. The charts of 407 patients admitted with "diverticular disease" between 2005 and 2010 were identified. For each admission, patients' demographics, presentations and management were recorded. Direct comparisons were made with results from the study by Rodkey and Welch. Of the 407 admissions studied, the distribution was 335 emergency and 72 elective. Medical management alone treated 90% of emergency admissions, while 4% required additional radiologic intervention. Emergency surgery was necessary in only 6% of cases with Hartmann's procedure being the most common procedure. Recurrent diverticulitis was a prime indication for elective surgery with 96% of cases undergoing a 1-staged procedure. Compared with the previous era, the nonoperative approach to managing acute diverticulitis is now applied for the vast majority of admissions. Improved success in medically temporizing patients in the present era has allowed for a higher percentage of successful single-staged elective surgeries.
