Objective To summarize the effect of treatment for common bile duct stones by laparoscope combined with choledocho-scope, and to assess the feasibility in judgment the patency of common bile duct by stone basket. Methods To review and analyze the clini-cal data of 32 patients who were given choledocholithiasis operation through laparoscope combined with choledochoscope,and the operation method,effect and complications were compared. Results In this research,32 choledocholithiasis operations were carried out using laparo-scope combined with choledochoscope from January 2013 to January 2014. The stones of 31 patients were taken out completely,and there were no stone in the other patient. All 32 patients recovered without any complication. After operation,all 32 patients showed unrestricted inferior bile common duct and no residual stone by T-tube cholangiography. Conclusion It showed satisfactory effect in treatment of choledocholithi-asis by laparoscope combined with choledochoscope. Compared to traditional laparotomy,which showed less injure and faster recovery. It is a simple and feasible method to judge the patency of common bile duct using large size stone basket combined with methylene blue injection.

【Objective】 To explore the safety and effectiveness of catheter aspiration combined with catheterization thrombolysis in the treatment of acute renal infarction (ARI), so as to provide reference for the treatment of this disease. 【Methods】 A retrospective analysis was conducted on the clinical and follow-up data of 11 ARI patients treated with catheter aspiration combined with catheter thrombolysis at our hospital during Jan.2019 and Jun.2023. 【Results】 Among the 11 patients, upon admission, 7 manifested with abdominal pain, 5 with lumbar pain, 5 with nausea, and 1 with fever.All patients were successfully treated with catheter aspiration combined with catheterization and thrombolysis.After thrombolysis, computed tomography angiography (CTA) showed the renal artery trunk and branch vessels.In 11 patients, the renal artery, branch artery and splenic artery branch vessels were patent.D2 aggregates returned to the normal level 1 month after surgery(<0.5 mg/L).During the follow-up of 3, 6, 12 months, no previous symptoms were observed.Ultrasound or CTA showed that the renal artery remained unobstructed. 【Conclusion】 The use of catheter aspiration combined with catheter thrombolysis for the treatment of ARI caused by renal artery thrombosis is effective, minimally invasive, and worth clinical promotion.
