BACKGROUND: Laparoscopic sigmoid resection is a feasible and frequent operation for patients who suffer from recurrent diverticulitis. There is still an ongoing debate about the optimal timing for surgery in patients who suffer from recurrent diverticulitis episodes. In elective situations the complication rate for this procedure is moderate, but there are patients at high risk for perioperative complications. The few identified risk factors so far refer to open surgery. Data for the elective laparoscopic approach is rare. The objective of this study was to identify potential predictive risk factors for intra- and postoperative complications in patients who underwent laparoscopic sigmoid resection due to diverticular disease. METHODS: Uni- and multivariate analyses of a prospectively gathered database (1993-2006) were performed on a consecutive series of 526 patients who underwent laparoscopic sigmoid resection due to recurrent diverticulitis in a single institution. Patients were assessed for demographic data, operative indications, and intra- and postoperative complications. Altogether, we analyzed 17 potential risk factors to identify significant influence on the intra- and postoperative outcome, including timing of surgery. RESULTS: Statistical analysis of specific medical and surgical complications revealed anemia, previous myocardial infarction, heart failure, experience of the surgeon, and male gender, as independent predictive risk factors for postoperative complications. Patients older than age 75 years was the only independent risk factor for intraoperative complications in a multiple logistic regression model. Early elective surgery led to increased conversion rate but did not influence the postoperative complication rate. CONCLUSIONS: This large, single-center study provides first evidence of the significance of specific predictive risk factors for intra- and postoperative complications in laparoscopic sigmoid resection for diverticular disease.
