We used modified and dynamic intraoperative cholangiography (IOC) navigation during laparoscopic subtotal cholecystectomy for difficult gallbladders. We have defined an IOC that does not open the cystic duct as a modified IOC. Modified IOC methods include the percutaneous transhepatic gallbladder drainage (PTGBD) tube method, the infundibulum puncture method, and the infundibulum cannulation method. Case 1 was chronic cholecystitis after PTGBD for acute cholecystitis with pericholecystic abscess. In this case, modified IOC was performed via PTGBD, and biliary anatomy and incarcerated stone were confirmed. Case 2 was chronic cholecystitis after endoscopic sphincterotomy for cholecystocholedocholithiasis. In this case, modified IOC was performed via gallbladder puncture needle, and biliary anatomy and incision line were confirmed. The target point on the laparoscopic image was determined by moving the tip of the grasping forceps under modified IOC, which we call modified and dynamic IOC. We conclude that the navigation by the modified and dynamic IOC via PTGBD tube or puncture needle is useful to identify biliary anatomy, incarcerated gallbladder stone, and safe incision line during laparoscopic subtotal cholecystectomy .
