We performed intraoperative ultrasonography with a miniature probe to explore the biliary anatomy, especially the cystic duct, during laparoscopic cholecystectomy. By using this radial-type probe introduced into a hard metal sheath with a balloon at the end, the plane containing Calot's triangle can be scanned easily when the gallbladder is extracted to the right side, thereby facilitating the identification of the cystic duct as well as the common ducts. In 30 cases, no common duct stone was found and the cystic duct was clearly identified. This radial-type miniature probe can be used to locate the cystic duct and avoid inadvertant incision or division of the common ducts.
在腹腔镜胆囊切除术中，我们使用微型探头进行术中超声检查，以探查胆道解剖结构，尤其是胆囊管。通过将这种径向型探头插入末端带有球囊的硬金属鞘内，当胆囊被牵向右侧时，可轻松扫描包含胆囊三角的平面，从而便于识别胆囊管和胆总管。在30例病例中，未发现胆总管结石，且胆囊管被清晰识别。这种径向型微型探头可用于定位胆囊管，避免无意中切开或切断胆总管。
