Abstract:
Objective To investigate the local anatomical characteristics of the cyctic duct and the feasibility of bile duct exploration through the cystic duct for stone removal and primary suture.Methods From February to September 2023,100 cases of secondary choledocholithiasis(SCL)were treated with laparoscopic transcystic common bile duct exploration(LTCBDE).During the operation,6 indicators were measured,including the direction of the gallbladder duct joining the common bile duct,the inner diameter of the gallbladder duct,the length of the gallbladder duct incision,the length of the gallbladder duct parallel to the common bile duct,the distance between the incised gallbladder duct or common bile duct and the upper edge of the duodenum,and the diameter of the stone taken by the cholangioscopy.Results The direction of the gallbladder duct joining into the common bile duct:92 cases at 9-12 o'clock,of which 76 cases at 10 and 11 o'clock,accounting for 76%;1 case each at 1 and 2 o'clock,accounting for 2%;2 and 4 cases at7 and 8 o'clock respectively,accounting for6%.The inner diameter of the cystic duct ranged from 3 mm to13 mm,with a median of 5.0 mm.The length of the common bile duct opened:21 cases(21%)had the common bile duct cut open,with an incision of 1-5 mm and a median of 3.0 mm.The parallel length of gallbladder duct and common bile duct:there was a parallel length of 2-40 mm and a median of 10.0 mm in36 cases.The distance between the incised gallbladder duct or common bile duct and the upper edge of the duodenum was5-20 mm,with a median of 15.0 mm.Intraoperative choledochoscope was used in 90 cases to remove stones,with a total of 128 stones removed.The diameter of the stones ranged from 1.5 mm to 22.0 mm,with a median of 5.0 mm.All the100 cases of LTCBDE were successful.A total of 83 cases(83%)were followed up for 3 months after surgery.After discharge,their appetite returned to normal,and they resumed normal life and work.There were no symptoms of bile duct stones such as abdominal pain,jaundice,or fever,and their liver function was normal.B-ultrasound showed a diameter of 5-10 mm for the common bile duct,with a median of 7 mm,and no postoperative stenosis.Conclusions Exploring the common bile duct through the cystic duct is feasible,with no or minimal damage to the common bile duct and no damage to the Oddi sphincter.It is the best way and surgical technique for laparoscopic exploration and stone removal via choledochoscope in SCL.
