To explore the effect of Laparoscopic Lithotomy and Open Laparotomy in the secondary bile duct operation of patients with choledocholithiasis.

Fifty cases with recurrent choledocholithiasis treated in our hospital from February 2014 to May 2017 were analyzed. They were randomly divided into laparoscopic group and open group with 25 cases in each group. SPSS21.0 statistical software was used for data analysis. Preoperative and postoperative measurement data were showed as (±s) deviation, compared with independent t test; Postoperative 24 h incidence of pain and postoperative complications were compared with χ² test, P<0.05 indicated the difference was statistically significant.

After surgery, The bleeding volume (P=0.004), gastrointestinal function recovery time (P=0.021), 24 h pain incidence (P=0.021) and hospitalization time (P=0.007) in laparoscopic group were significantly lower than those in laparotomy group. However, the operation time (P=0.028) and the total cost of patients (P= 0.046) in laparoscopic group were significantly higher than those in laparotomy group. After surgery, the incidence of complications in the laparotomy group was significantly higher than that in the laparoscopy group(36% vs. 12%, P=0.037). The clinical effective rate of the two groups was 100%.

The clinical efficacy of laparoscopic secondary biliary surgery and open secondary biliary surgery is similar, however, the incidence of postoperative complications of laparoscopic secondary biliary surgery is lower. Laparoscopic secondary biliary surgery is more safe and effective.
