Following cholecystectomy, 50 patients were randomly allocated for suction drainage by small (2.5 mm) Redivac or large calibre (6 mm) Redivac drains. There were 25 patients in each group. Subhepatic collection was detected by ultrasonic examination in 5 patients on the seventh postoperative day. The smaller drain was used in all of these patients. Of these 5 patients, one developed pulmonary infection, a second had internal bleeding requiring laparotomy, while the remaining 3 were asymptomatic. Subhepatic fluid was not detected in any patient who had the larger drain.
胆囊切除术后，50例患者被随机分为两组，分别使用小口径（2.5毫米）的Redivac引流管或大口径（6毫米）的Redivac引流管进行负压引流。每组25例患者。术后第七天，超声检查发现5例患者存在肝下积液。所有这5例患者均使用了较小的引流管。在这5例患者中，1例发生肺部感染，1例出现内出血需行剖腹手术，其余3例无症状。使用较大引流管的患者均未检测到肝下积液。
