To the Editor The Scandinavian Diverticulitis (SCANDIV) Study Group1 investigated the safety and efficacy of laparoscopic peritoneal lavage compared with primary resection for acute perforated diverticulitis. To date, this trial represents the largest randomized clinical trial on this subject and confirmed that safety issues are serious in patients undergoing laparoscopic lavage. We would like to point out some aspects of the SCANDIV trial that, in our opinion, need to be clarified.
