In this prospective randomized study, the influence of an intraperitoneal drain on the incidence and clinical significance of subhepatic collections occurring in patients after acute or elective cholecystectomy was assessed by ultrasound examination. A total of 112 patients entered the study, of whom 54 received a drain. There was no significant difference between the drainage and the non-drainage groups with respect to mean age or sex distribution, the number of patients in whom the gallbladder bed was formally closed (27 versus 21) nor in the number of acute cholecystectomies performed in either group (12 versus 13). Ultrasound detected 10 (18 per cent) collections in the drainage group and only one (1.8 per cent) in the non-drainage group (P less than 0.01, chi 2 test). None of the collections required any further treatment and no morbidity occurred that was directly attributable to the presence of the retained fluid. These results suggest that rather than preventing fluid collections, suction drains may predispose to the development of subhepatic collections after cholecystectomy.
在这项前瞻性随机研究中，通过超声检查评估了腹腔引流管对急性或择期胆囊切除术后患者肝下积液发生率及临床意义的影响。共有112例患者进入研究，其中54例放置了引流管。引流组和非引流组在平均年龄、性别分布、胆囊床正式闭合的患者数量（27例对21例）以及两组中进行急性胆囊切除术的患者数量（12例对13例）方面均无显著差异。超声检查发现引流组有10例（18%）积液，而非引流组仅有1例（1.8%）（P<0.01，卡方检验）。所有积液均无需进一步治疗，也未发生直接归因于残留液体的并发症。这些结果表明，胆囊切除术后，吸引引流管可能不是预防积液，而是易引发肝下积液。
