A Study On Reserve Intact Oddi Sphincter And Minimally Invasive Treatment Of Choledocholithiasis Patients

Objective To research in reserve intact Oddi Sphincter and minimally invasive treatment of choledocholithiasis patients.Methods A analysis of clinical data of 60 cases of laparoscopic cholecystectomy combined endoscopic sphincterotomy,laparoscopic common bile duct exploration (T tube drainage) and laparoscopic common bile duct exploration (preoperative insertion of nasobiliary tube and primary suture of common bile duct) due to choledocholithiasis choledocholithiasis,were randomly divided into three groups, the clinical effects of three treatment methods were compared with 20 cases of preoperative insertion of nasobiliary tube and primary suture of common bile duct(Nasobiliary group) and 20 cases of T-tube drainage (T-tube group) and 20 cases of laparoscopic cholecystectomy combined with endoscopic sphincterotomy (EST group). Results three of the groups successfully completed operation, The extubation time of nasobiliary group was (8.25±1.21) d. The postoperative hospitalization(8.50±4.05) d, which were all shorter than those of T-tube group(31.60±5.38d, and 13.6±3.97d, respectively), choledocholithiasis recurrence rate and long-term reflux cholangitis less than there are EST group, with significant differences(P<0.05); Comparison of postoperative complications in the three groups, no significant difference(P>0.05)。Conclusions Preoperative insertion of nasobiliary tube and primary suture of common bile duct can prevent not only bile leakage caused by increased biliary pressure after primary suture, Patients avoid the pain of along time with a tube, And shorten the hospital stay, retain the structural integrity of Oddi sphincter, Maintain the normal function of Oddi sphincter, Avoid the result of postoperative reflux cholangitis and stone recurrence rate was caused by Oddi sphincter structural damage.
