Common bile duct (CBD) stones are present in approximately 3 % to 16 % patients with symptomatic gallstones [1] [2] [3]. Laparoscopic common bile duct exploration (LCBDE) and laparoscopic cholecystectomy (LC) could treat cholecysto-choledocholithiasis in one session. However, some drawbacks including the unsatisfactory controllability of the surgical choledochoscope, postoperative bile leak, and the use of the T-tube have hindered the further development of LCBDE + LC. To solve these problems, we introduced LCBDE through the cystic duct using a more flexible cholangioscope combined with cholecystectomy for cholecysto-choledocholithiasis.

A 59-year-old man with abdominal pain underwent computed tomography (CT) examination and the result showed cholecysto-choledocholithiasis. He chose LCBDE + LC to treat the gallstones and CBD stones in one session. During this procedure, we used a novel cholangioscope with flexible controllability, which was initially designed as a single-operator peroral cholangioscopy system [4].

First the gallbladder, cystic duct, and cystic artery were dissociated under laparoscopy, and the cystic artery was cut off using the electrocoagulation function. Then a 5-mm incision was created on the cystic duct ([Fig. 1 a]). The cholangioscope was inserted into the cystic duct through the trocar with the help of the laparoscope ([Fig. 1 b]). Multiple CBD stones were found and extracted using a basket under cholangioscopy in multiple sessions ([Fig. 2], [Fig. 3]). No residual stones were found under cholangioscopy and cholangiography ([Fig. 4]). Finally, the cystic duct was clamped, and the gallbladder was removed ([Fig. 5], [Video 1]). The patient’s recovery was smooth without any adverse events.

Quality:

Of note, this is the first experience of this technique in our team, and we hope that patients with cholecysto-choledocholithiasis can benefit from this procedure if conditions allow.

The advantages of this technique over traditional LCBDE + LC include better controllability, enabling complete clearance of CBD stones, and a smaller incision in the cystic duct instead of the CBD, avoiding the placement of a T-tube and postoperative bile leak.
