Cost structure of laparoscopic and open sigmoid colectomy for diverticular disease: similarities and differences.

Purpose: Although laparoscopic colectomy has demonstrated a variety of advantages, it remains unclear whether the reductions in length of stay and faster return of bowel function will offset potential increases in cost caused by operating time and instrumentation. The purpose of this study was to compare the direct cost structure of elective open and laparoscopic resection for sigmoid diverticulitis.

Methods: We compared consecutive elective open and laparoscopic sigmoid colectomies (n = 71 and n = 61, respectively) performed from March 1, 1999, through December 31, 2000.
