Dr Scheidbach and colleagues from Germany undertook a study to analyze changes regarding the indications for and results of laparoscopic treatment of sigmoid diverticulitis.
The researchers collected data within the framework of an ongoing prospective multicenter study carried out by the Laparoscopic Colorectal Surgery Study Group.
The research team divided the institutions participating in the study into 3 groups by experience (Group I, >100 procedures; Group II, 30–100 procedures; Group III, <30 procedures).
The researchers noted that among the 3,868 recruited patients, sigmoid diverticulitis (40 %) was by far the most common indication for surgery.
Sigmoid resection (55.9 %) was by far the most common laparoscopic procedure.

The researchers found that a total of 1,353 patients (87.6 %) had uncomplicated diverticulitis, whereas 192 (12.4 %) had a complicated form of diverticular disease (Hinchey I–IV, diverticular bleeding, fistula formation).
In addition, they found that cases of complicated diverticulitis were significantly more frequently operated on at institutions with greater experience (Group I, 20.8 %; Group II, 8.7%; Group III, 7.9%).
Despite this fact, these institutions still had better intraoperative complication rates, conversion rates, and postoperative morbidity and mortality rates.
Dr Scheidbach concluded, "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."
