["Perforated diverticulitis often requires surgery with a colon resection such as Hartmann's procedure, with inherent morbidity. Recent studies suggest that laparoscopic lavage may be an alternative surgical treatment. The aim of this study was to compare re-operations, morbidity, and mortality as well as health economic outcomes between laparoscopic lavage and colon resection for perforated purulent diverticulitis.", 'PubMed, Cochrane, Centre for Reviews and Dissemination, and Embase were searched. Published randomized controlled trials and prospective and retrospective cohorts with laparoscopic lavage and colon resection as interventions were identified. Trial limitations were assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. Re-operations, complications at 90\xa0days classified according to Clavien-Dindo and mortality were extracted.', 'Three randomized trials published between 2005 and 2015 were included in the analysis. The studies included a total of 358 patients with 185 patients undergoing laparoscopic lavage. At 12\xa0months, the relative risk of having a re-operation was lower for laparoscopic lavage compared to colon resection in the two trials that had a 12\xa0month follow-up. We found no significant differences in Clavien-Dindo complications classified more than level IIIB or mortality at 90\xa0days.'] Is laparoscopic lavage superior to colon resection for perforated purulent diverticulitis-a meta-analysis?
