It was the aim of this prospective study to evaluate the outcome of laparoscopic surgery for diverticular disease.
All patients who underwent elective laparoscopic colectomy for diverticular disease within a 10-year period were prospectively entered into a PC database registry. Indications for laparoscopic surgery were acute complicated diverticulitis (Hinchey stages I and IIa), chronically recurrent diverticulitis, sigmoid stenosis or outlet obstruction caused by chronic diverticulitis. Surgical procedures (sigmoid and anterior resection, left colectomy and resection rectopexy) included intracorporeal dissection and colorectal anastomosis. Parameters studied included age, gender, stage of disease, procedure, duration of surgery, intraoperative technical variables, transfusion requirements, conversion rate, total complication rate including major (requiring re-operation), minor (conservative treatment) and late-onset (post-discharge) complication rates, stay on ICU, hospitalisation, mortality, and recurrence. For objective evaluation, only laparoscopically completed procedures were analysed. Comparative outcome analysis was performed with respect to stage of disease and experience.
A total of 396 patients underwent laparoscopic colectomy. Conversion rate was 6.8% (n=27), so that laparoscopic completion rate was 93.2% (n=369). Most common reasons for conversion were directly related to the inflammatory process, abscess or fistulas. The most common procedure was sigmoid resection (n=279), followed by anterior resection (n=36) and left colectomy (n=29). Total complication rate was 18.4% (n=68). Major complication rate was 7.6% (n=28), whereas the most common complication requiring re-operation was haemorrhage in 3.3% (n=12). Anastomotic leakage occurred in 1.6% (n=6). Minor complications were noted in 10.7% (n=40), late-onset complications occurred in 2.7% (n=10). Mortality was 0.5% (n=2). Mean duration of surgery was 193 (range 75–400) min, return to normal diet was completed after 6.8 (range 3–19) days. Mean hospital stay was 11.8 (range 4–71) days. No recurrence of diverticulitis occurred.
Laparoscopic surgery for diverticular disease is safe, feasible and effective. Therefore, laparoscopic colectomy has replaced open resection as standard surgery for recurrent and complicated diverticulitis at our institution.
