Efficacy of laparoscopic choledochotomy and T tube drainage for the patients of extrahepatic bile duct stones

Abstract

Objective To observe the effect and quality of life score of laparoscopic choledochotomy and T tube drainage for the patients of extrahepatic bile duct stones. Methods A total of 80 patients with calculus of extrahepatic bile duct in Shandong Provincial Third Hospital from February 2016 to April 2017 were retrospectively analyzed, including 41 males and 39 females, among which, 40 patients were treated with laparoscopic choledocholithotomy and T tube drainage(the study group), and the other 40 cases were operated on laparotomy(the control group) by hierarchical randomization grouping. After operation, the time of operation, the amount of bleeding during the operation, the time of postoperative exhaust, the time of postoperative hospitalization and the difference of adverse reactions were observed in the two groups. Follow-up at the end of 1st and 3th month, quality of life score was compared between the two groups. The measurement data with normal distribution were expressed as mean±standard deviation (Mean±SD), comparison between groups were performed using t test. The count data were expressed as rate(%), comparison between groups were performed using chi-square test. Results Comparison of data between the study group and the control group: operation time respectively were (97.23±10.21) min, (117.52±10.01) min, the amount of bleeding respectively were(87.73±10.54) ml, (185.13±11.56) ml, postoperative exhaust time respectively were (17.57±2.96) h, (38.44±3.06) h and the postoperative hospitalization time were (7.75±1.21) d, (12.03±3.85) d. The data of each group in the study group were lower than those in the control group, and the difference was statistically significant(P 0.05). Conclusions Compared with open surgery, laparoscopic choledocholithotomy with T tube drainage has significant clinical effect in the treatment of extrahepatic bile duct stones. It can improve the quality of life and safety, and it is suitable for clinical application. Key words: Laparoscopes; Common bile duct; Cholelithiasis; Quality of life score; T tube drainage
