Intraoperative Cholangiography during Cholecystectomy Using a Biliary-nose Tube: Routinely Used in Patients with Main Bile Duct Stones

Background: Nowadays, the "gold standard" treatment for gallbladder stones is laparoscopic cholecystectomy but the risk of iatrogenic biliary duct injuries is increased compared to "open" surgery. Intraoperative cholangiography (IOC) can be useful to avoid biliary injuries but it can also be a no-safe procedure in center in which it is not routinely performed. Aim and objective: The aim of our study is to trust the efficacy of IOC in a patient with common bile duct (CBD) and gallbladder stones using a biliary-nose tube. Materials and methods: 135 patients with gallbladder and CBD stones were treated with sequential therapy and randomly divided into two groups. Laparoscopic cholecystectomy was performed within 24/48 h. During endoscopic retrograde cholangiopancreatography, a biliary-nose catheter was left to perform cholangiography during the following surgical procedure. Group A had also a cholangiography at the beginning of the surgical procedure in order to evidence biliary duct structure. Results: Cholangiography avoided a lesion of the biliary ducts in nine patients. Only a patient had a residual stone in the CBD. The dissection at Calot's triangle was faster in group A patients without differences between the surgeons involved.
