目的 探讨白试验在肝切除手术中检测漏胆的价值。方法 笔者所在医院2008年1月至2013年1月期间在肝切除手术中采用白试验联合干纱布擦拭法检测漏胆56例。即在肝切除手术操作末期，用干纱布擦拭法确认无漏胆后，经胆囊管或左右肝管插管注入5%无菌脂肪乳剂10～30mL，同时用手阻断远端胆总管。观察肝切除手术创面的白色液体渗出情况，对渗出白色液体处予以间断缝合。重复操作，至断面无白色液体渗出为止。结果 56例患者经术中检测，发现漏胆17例（漏胆检出率为30.4%），每例发现漏胆1～6处（平均2.9处），术中均予以确切缝合以关闭漏胆处，且重复试验操作，证实均再无漏胆。术后发生漏胆2例（3.6%），经相应治疗后痊愈出院。全部患者出院后均随访3～6个月（平均3.8个月），无膈下积液或膈下感染病例发生。结论 术中白试验能够发现漏胆的精确部位，不会污染肝切除手术创面，并能够无限次地重复试验，值得临床推广。
ObjectiveTo summarize the clinical experience on primary suture after common bile duct exploration and to investigate its clinical indications and curative effects. MethodsThe clinical data of 137 patients underwent primary closure of common bile duct between February 2006 and June 2010 were analyzed retrospectively. ResultsAll operations were successful. The operative time ranged from 65-213 min (mean 129 min) and the blood loss ranged from 50-350 ml with an average of 148 ml. One hundred and twenty-four patients (90.5%) were discharged from hospital without complications within 7 d after operation. Postoperative bile leakage occurred in 13 patients (9.5%) consisted of 10 early stage cases (18.5%, 10/54) and 3 later stage cases (3.6%, 3/83), which were discharged with improvement by conservative treatment within 3 weeks after operation. Totally 113 patients (82.5%) were followed up for 2-54 months with a median time of 14 months, no residual or retained stone and biliary duct stricture occurred. ConclusionOnly with the strict indication and proficient surgical technology, primary suture after common bile duct exploration is a safe and effective way to choledocholithiasis.
