BACKGROUND Laparoscopic choledocholithotomy for a large impacted common bile duct(CBD)stone is a challenging procedure because of the technical difficulty and the possibility of postoperative complications,even in this era of minimally invasive surgery.Herein,we present a case of large impacted CBD stones.CASE SUMMARY A 71-year-old man showed a distal CBD stone(45 mm×20 mm)and a middle CBD stone(20 mm×15 mm)on computed tomography.Endoscopic retrograde cholangiopancreatography failed due to the large size of the impacted stone and the presence of a large duodenal diverticulum.Laparoscopic choledocholithotomy was decided,and we used a near-infrared indocyanine green fluorescence scope to detect and expose the supraduodenal CBD more accurately.Then,the location,size,and shape of the stones were detected using a laparoscopic intraoperative ultrasound.The CBD was opened with a 2-cm-sized vertical incision.After irrigating several times,two CBD stones were removed with the Endo BabcockTM.T-tube insertion was done for postoperative cholangiography and delayed the removal of remnant sludge.The patient had no postoperative complications.CONCLUSION Laparoscopic choledocholithotomy by transcholedochal approach and transductal T-tube insertion is a safe and feasible option for large-sized impacted CBD stones.
