This randomized, prospective study evaluates drainage of the subhepatic space in patients undergoing simple, uncomplicated cholecystectomy. One hundred twenty-two patients were divided into open (Penrose) drainage, closed sump drainage and no drainage groups. Open drainage resulted in increased morbidity and a longer postoperative hospital stay. The best results were in patients without drains. Subhepatic drainage is unnecessary in simple, uncomplicated cholecystectomy.
