A study of patients who had a cholecystectomy compared the use of sump drains and Penrose drains. Sump drains were removed as soon as the indication for the presence of the drain no longer existed. Penrose drains were managed in the traditional way. The safety of early drain removal in selected patients was demonstrated. This technique offers most of the advantage and little of the risk of omitting drains entirely. The length of hospital stay for those patients who underwent a cholecystectomy can be significantly shortened by this technique;
一项针对接受胆囊切除术患者的研究比较了负压引流管和橡皮引流管的使用情况。一旦引流指征不再存在，负压引流管即被拔除。橡皮引流管则采用传统方式处理。研究证明了在特定患者中早期拔除引流管的安全性。该技术具有大部分保留引流管的优点，且几乎没有完全省略引流管的风险。采用此技术可显著缩短接受胆囊切除术患者的住院时间。
