Objective To comparatively analyze the effects of laparoscopic and open left hepatectomy on intrahepatic bile duct stones. Methods Ninety-one patients with intrahepatic bile duct stones were divided into observation group (48 cases) and control group (43 cases) according to different surgical methods. The patients in observation group underwent laparoscopic left hepatectomy and the patients in control group underwent traditional open left hepatectomy. The intraoperative conditions (operation time, intraoperative blood loss), postoperative conditions (postoperative exhaust time, postoperative time of leaving bed, postoperative hospitalization time), postoperative complications (pneumonia, incision infection, bile leakage, abdominal bleeding), residual stones and recurrence of stones of two groups were compared. Results The operation time of patients in observation group was significantly longer than control group (P<0.05); While the postoperative exhaust time, postoperative time of leaving bed and postoperative hospital stay of were significantly shorter (P<0.05). There was no significant difference in intraoperative blood loss, the incidence of postoperative complications, the residual stone rate, and the recurrence rate between two groups (P>0.05). Conclusion Treating intrahepatic bile duct stones with laparoscopic left hepatectomy has the advantages of less trauma and rapid postoperative recovery, and is worthy of popularization and application in hospitals with conditions.

Objective: To investigate the diagnostic value of procalcitonin (PCT) and interleukin 6 (IL-6) in acute cholecystitis combined with bacterial infection. Methods: 82 acute cholecystitis patients were divided into bacterial infection group (n=25) and non bacterial infection group (n=57) according to whether had bacterial infection. The blood PCT and IL-6 level of all the patients were detected and ROC curve was established to evaluate the diagnostic value of PCT and IL-6 in acute cholecystitis combined with bacterial infection. Results: The PCT and IL-6 level of acute cholecystitis patients in bacterial infection group were obviously higher than non bacterial infection group (P<0.05). The AUC of PCT was 0.904, 95% confidence interval was 0.819~0.989; the AUC of IL-6 was 0.855, 95% confidence interval was 0.738~0.972. Conclusions: The PCT and IL-6 level of acute cholecystitis combined with bacterial infection patients significantly increase, and both of them have high diagnostic value in judging acute cholecystitis combined with bacterial infection.
