Passive drainage after elective cholecystectomy was studied in six patients. Their erythrocytes were labeled in vitro with technetium-99mTc and injected via the drain after operation. After one hour, we were able to recover labeled erythrocytes and free pertechnetate from peripheral blood. After 24 hours, a large part of the injected erythrocytes had been evacuated via the drain. In eight patients subjected to cholecystectomy, 99mTc-HIDA was injected intravenously after the operation. In four cases, in which the gallbladder bed was raw, the activity ratio discharge/blood rapidly reached extremely high values. In the other four cases, in which the liver surface had not been denuded, the ratio was much lower. Passive drainage is a useful device for evacuation intra-abdominal bile or hemolysed blood after cholecystectomy, especially when the gallbladder bed has been denuded.
对6例择期胆囊切除术后的患者进行了被动引流研究。将他们的红细胞在体外标记上锝-99mTc，并在术后通过引流管注入。1小时后，我们能够从外周血中回收标记的红细胞和游离高锝酸盐。24小时后，大部分注入的红细胞已通过引流管排出。对8例接受胆囊切除术的患者，术后静脉注射99mTc-HIDA。在4例胆囊床有创面的病例中，引流/血液的活性比迅速达到极高值。在另外4例肝脏表面未被剥脱的病例中，该比值则低得多。被动引流是胆囊切除术后排出腹腔内胆汁或溶血血液的一种有用方法，尤其是当胆囊床已被剥脱时。
