肝外胆道腔镜手术中胆道造影术的临床意义

通过腹腔镜微创技术不断的发展及完善，腹腔镜胆道外科技术体系已进入精准时代，朝着更安全、高效、微创的方向发展。随着腹腔镜技术的推广，胆道术后并发症发生率有所上升，如何预防其发生是关键所在。目前，常应用术中胆道造影及吲哚菁绿荧光胆道造影技术于腹腔镜胆道术中以预防胆管损伤，明确术中有无结石遗漏及胰胆管变异，了解术中胆总管通畅程度及Oddis括约肌的功能状态。

The clinical significance of cholangiography in extrahepatic cholangioscopy

With the continuous development and improvement of laparoscopic minimally invasive technology, the technical system of laparoscopic biliary tract surgery has entered the era of precision medicine and is developing towards a safer, more efficient and minimally invasive direction. However, how to prevent its occurrence is the key. At present, intraoperative cholangiography and indocyanine green fluorescence cholangiography are often used in laparoscopic biliary surgery to prevent bile duct injury; to determine whether there is stone omission and bile duct variation during surgery and to understand the intraoperative patency of the common bile duct and the functional status of Oddis sphincter.
