Objective:the purpose of this study is to investigate the efficacy,feasibility,reliability,and safety of laparoscope combined air-pressure ballistic lithotripsy in the treatment of patients with bile duct stones. Methods:We are going to select 60 patients diagnosed with hepatolithiasis who carry on the treatment in our hospital from April 2014 to April 2015.According to the unified inclusion and exclusion criteria,the patients are divided into the experimental group and the control group.The experimental group use the treatment of laparoscope combine with air-pressure ballistic lithotripsy to treat hepatolithiasis,while the control group treat the patients with hepatolithiasis with the method of lobectomy and segmental resection of liver.Contrastive analyzed two group of patients' clinical care effects. Research hypothesis:according to compare two groups' duration of surgery,blood loss,postoperative complication rate,hospital stay,the stone clearance rate,,the residual stone rate,reoperation rate etc.We suppose that the clinical results of the experimental group are superior to the control group,difference is statistically significant(P\<0.05).So we can draw the conclusion that the method of laparoscope combined air-pressure ballistic lithotripsy is useful in treatment of patients with hepatolithiasis.
