The benefits of some ancillary techniques of cholecystectomy are exaggerated by retrospective study of selected patients. Therefore, the authors performed a prospective, randomized study of 100 consecutive patients who underwent simple elective cholecystectomy for chronic cholecystitis and cholelithiasis. No patient was excluded because of incomplete hemostasis or fear of bile leakage. The frequency of pulmonary complications and wound infections was independent of the type of incision--vertical or subcostal. Peritoneal drainage was found to be unnecessary. Short-term drainage may increase the frequency of postoperative fever, but did not increase pulmonary complications or wound infections. In these patients, intra-abdominal sepsis is rare; wound infections were uncommon and the gallbladder bile was usually sterile and not the cause of postoperative infection.
某些胆囊切除术辅助技术的益处通过对特定患者的回顾性研究被夸大了。因此，作者对100例因慢性胆囊炎和胆结石接受单纯择期胆囊切除术的连续患者进行了一项前瞻性、随机研究。没有患者因止血不完全或担心胆漏而被排除。肺部并发症和伤口感染的发生率与切口类型（垂直或肋下）无关。发现腹腔引流是不必要的。短期引流可能会增加术后发热的频率，但不会增加肺部并发症或伤口感染。在这些患者中，腹腔内脓毒症很少见；伤口感染不常见，胆囊胆汁通常无菌，不是术后感染的原因。
