RESUMEN
Objective To investigate the value of endoscopic papillary incision combined with balloon di-lation in the treatment of choledocholithiasis with periampullary diverticula(PAD). Methods A total of 118 pa-tients with choledocholithiasis and PAD admitted to our hospital from January 2015 to January 2017 were retrospec-tively analyzed.According to the operation method,all patients were divided into two groups:sEST+EPBD group (60 cases)and EST group(58 cases).The success rate of ERCP and the success rate of one-step stone removal, the changes of serum TBil and DBil before and after operation,and the incidence of postoperative complications were compared between the two groups. Results The successful rates of ERCP and stone removal in sEST+EPBD group were significantly higher than those in EST group(P < 0.05). The levels of serum TBil and DBil in both groups were significantly lower than those before operation(P<0.05).The overall incidence of postoperative com-plications in sEST + EPBD group was significantly lower than that in EST group(P < 0.05). Conclusions The treatment of choledocholithiasis with PAD in patients with endoscopic papillary small incision and balloon dilation treatment effect is significant,which can significantly improve the success rate of ERCP and success rate of one-time stone,benefitting the prognosis of patients.
