Effectiveness of Elective Laparoscopic Treatment for Colonic Diverticulitis

Background and Objectives: To analyze the short-and long-term outcomes of laparoscopic sigmoid colectomy for the elective treatment of diverticular disease. Methods: A consecutive unselected series of 94 patients undergoing elective laparoscopic sigmoid colectomy for diverticular disease from 2008 to 2012 was analyzed. We collected patients-, surgery- and hospital stay-related data, as well as the short- and long-term outcomes. Operative steps, instrumentation, and postoperative cares were standardized. Comorbidity was assessed by Charlson comorbidity index. Complications were classified using the Clavien-Dindo classification system. The qualitative long-term assessment was carried out by subjecting patients to the validated gastrointestinal quality of life index questionnaire before and after surgery. Results: The mean age of our cohort was 61.3 +/- 11.0 years with a Charlson comorbidity index of 1.2 +/- 1.5. Mean operative time was 213.5 +/- 60.8 minutes and estimated blood loss was 67.2 +/- 94.3 mL. We had 3 cases (3.2%) of conversion to open laparotomy. The rates of postoperative complications were 35.1%, 6.3%, 2.1%, and 1.06%, respectively, for grades 1, 2, 3b, and 5 according to the Clavien-Dindo system. Length of hospital stay was 8.1 +/- 1.9 days, and we have not recorded readmissions in patients discharged within 60 days after surgery. Median follow-up was of 9.6 +/- 2.7 months. We observed no recurrence of diverticular disease, but there was evidence of 3 cases of incisional hernia (3.19%). The difference between preoperative and late gastrointestinal quality of life index score was statistically significant (97.1 +/- 5.8 vs 129.6 +/- 8.0). Conclusions: Elective laparoscopic treatment of colonic diverticular disease represents an effective option that produces adequate postoperative results and ensures a satisfactory functional outcome.
