Abstract:Objective To explore the safety and value of retained guide wire in patients with large bile duct stones.Method Clinical data of 308 patients with large bile duct stones (1.2 ~ 1.5 cm in diameter) from January 2017 to December 2019 were analyzed retrospectively. Among of them, 152 cases in net basket group, 42 cases in balloon group, 38 cases in net basket combined with balloon group and 76 cases in wire-guide group. The effect of various methods of stone extraction is analyzed.Result The success rate of stone removal in the wire-guide group was higher than that in the other groups, but there was no statistical difference (P > 0.05); The incidence of stone incarceration in the wire-guide group was significantly lower than that in the other groups (P < 0.05); The total incidence of complications after endoscopic retrograde cholangiopancreatography (ERCP) in the wire-guide group was 10.5% (8/76), lower than that in the other groups, but there was no significant difference (P > 0.05). In the wire-guide group, post-ERCP pancreatitis and hyperamylasemia were lower than those in the other groups, but there were no significant differences (P > 0.05). There was no significant difference in postoperative cholangitis among four groups (P > 0.05). There were 1 case of delayed bleeding in the basket group and 1 case in the combined group, which was improved after endoscopic hemostasis, no perforation or death occurred in all four groups. The operation time of the wire-guide group was significantly shorter than that of the other groups (P < 0.05), and the hospitalization time of the wire-guide group was shorter than that of the other groups, but not statistically significant (P > 0.05).Conclusion The retention of biliary guide wire can improve the success rate of one-time stone extraction, reduce the probability of stone nipple incarceration, shorten the ERCP operation time .
