BACKGROUND: BACKGROUND:The aim of the present study was to analyze changes regarding the indications for and results of laparoscopic treatment of sigmoid diverticulitis.
METHODS: METHODS:The data were collected within the framework of an ongoing prospective multicenter study carried out by the Laparoscopic Colorectal Surgery Study Group and were submitted to a statistical subgroup analysis. The institutions participating in the study were divided into three groups by experience (Group I, >100 procedures; Group II, 30-100 procedures; Group III, <30 procedures).
RESULTS: RESULTS:Among the 3,868 recruited patients, sigmoid diverticulitis (n = 1,545, 40 percent) was by far the most common indication for surgery, and sigmoid resection (n = 2,160, 55.9 percent) was by far the most common laparoscopic procedure. A total of 1,353 patients (87.6 percent) had uncomplicated diverticulitis, whereas 192 (12.4 percent) had a complicated form of diverticular disease (Hinchey I-IV, diverticular bleeding, fistula formation). Cases of complicated diverticulitis were significantly more frequently operated on at institutions with greater experience (Group I, 20.8 percent; Group II, 8.7 percent; Group III, 7.9 percent). Despite this fact, these institutions still had better intraoperative complication rates (Group I, 5.0 percent; Group II, 5.8 percent; Group III, 6.9 percent), conversion rates (Group I, 4.4 percent; Group II, 6.7 percent; Group III, 7.7 percent), and postoperative morbidity (Group I, 15.9 percent; Group II, 16.6 percent; Group III, 18.6 percent) and mortality (Group I, 0.2 percent; Group II, 0.5 percent; Group III, 0.4 percent) rates.
CONCLUSION: CONCLUSION:An increase in experience is associated with an expansion of laparoscopic indications to include complicated forms of diverticulitis, with comparable intraoperative and postoperative complication rates, operating time, and mortality rates.
