Complete clearance of intrahepatic stones has long been a major surgical challenge. To reduce the incidence of residual stones, we used intraoperative ultrasonography (IOUS) to localize them and guide lithectomy in 38 patients with hepatolithiasis between July 1988 and December 1993. All patients had multiple intrahepatic stones; 24 had accompanying extrahepatic calculi. Hepatic stones were confined to the left intrahepatic biliary tract in 13 patients, to the right in 9, and in both lobes in 16. Twenty-three patients underwent common bile duct exploration followed by T-tube drainage, 8 had transhepatic lithotomy with or without choledocholithotomy, 3 had choledocolithotomy and Roux-en-Y side-to-side choledochojejunostomy, and 2 had hepaticojejunostomy, left lobectomy was performed in the remainder. In 35 patients cholecystectomy was performed at the same time. Complete clearance of the stones was achieved in 36 patients (94.7%). The incidence of retained stone was decreased to 5.3%. No associated complications occurred. IOUS can accurately localize intrahepatic calculi, directly orient lithotomy instruments to approach the stones, demonstrate the spatial relation between stone and intrahepatic critical structure, and thereby choose an optical route for transhepatic lithotomy. Imaging can be repeated at any time with no radiation exposure to the patient or the medical staff. : 1996 by the Société Internationale de Chir, ugie Zhang Wei Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut Niu Hai-Ou Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut Zhao Guang-Wu Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut Su Ke-Jun Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut Wei Hong-Chen Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut Su Zi-Xia Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut Huai Jian-Cun Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut https://doi.org/10.1007/s002689900009 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/s002689900009 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Zhang Wei Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut NATIONALLICENCE 700 1- Niu Hai-Ou Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut NATIONALLICENCE 700 1- Zhao Guang-Wu Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut NATIONALLICENCE 700 1- Su Ke-Jun Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut NATIONALLICENCE 700 1- Wei Hong-Chen Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut NATIONALLICENCE 700 1- Su Zi-Xia Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut NATIONALLICENCE 700 1- Huai Jian-Cun Department of Surgery, Second Affiliated Hospital, Henan Medical University, 2 Jingba Road, Zhengzhou, Henan 450003, People's Republic of China, CN aut Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
