Abstract：Objective Discussing the clinical application value of laparoscopic ultrasound-guided partial hepatectomy in treating recurrent hepatolithiasis with hilar and intrahepatic bile duct stenosis.Methods A retrospective analysis of clinical data was conducted on 29 patients with hepatobiliary duct stones who underwent laparoscopic hepatectomy at North Sichuan Medical College Affiliated Hospital from January 2021 to January 2023.All patients had a history of previous biliary surgery,According to whether laparoscopic ultrasound was used,the patients were divided into an observation group(13 cases)and a control group(16 cases).During the surgery,laparoscopic ultrasound was used to precisely locate intrahepatic biliary stones,identify areas of bile duct stenosis,and determine the course of intrahepatic bile ducts and blood vessels.Simultaneously,while resecting liver tissue or exposing the hepatic hilum,we employed real-time laparoscopic ultrasound to monitor bile duct stenosis and dilations,complemented by cholangioscopy for exploration and stone retrieval within the remaining liver lobes.Results There was no significant difference in operation time[(333.3±62.11)min vs.(332.9±82.0)min,P=0.989],intraoperative blood loss[(241.5±151.3)mL vs.(341.9± 232.9)mL,P=0.192],postoperative complications(30.8％)vs.(43.8％),P=0.702,postoperative residual stones 7.7％vs.31.3％,P=0.183,stone recurrence 0 vs.18.8％,P=0.232 between the two groups.There was a significant difference in the number of previous operations between the two groups(P＜0.05).Conclusion Laparoscopic ultrasound is helpful in clarifying the location and scope of hepatolithiasis the location of bile duct stenosis,and the course of important blood vessels.It can provide real-time guidance and assistance for patients with multiple histories of biliary tract surgery.
