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.
这项随机前瞻性研究评估了接受简单、无并发症胆囊切除术患者的肝下间隙引流情况。122例患者被分为开放（彭罗斯）引流组、闭式负压引流组和不引流组。开放引流导致发病率增加和术后住院时间延长。不放置引流管的患者效果最佳。在简单、无并发症的胆囊切除术中，肝下引流并无必要。
