Malignancy
NO
The purpose of this study is to prospectively evaluate the safety and feasibility of fluorescence-guided biliary navigation using direct intrabiliary or intracholecystic injection of indocyanine green (ICG). In particular, this study aims to assess the utility of this technique for intraoperative visualization of biliary anatomy, identification of bile leakage sites, and surgical navigation during hepatobiliary procedures.
Safety,Efficacy
1. Incidence of adverse events related to direct intrabiliary or intracholecystic injection of indocyanine green
2. Successful intraoperative biliary visualization rate
3. Visibility assessment of biliary anatomy during fluorescence navigation
Interventional
Single arm
Non-randomized
Open -no one is blinded

Treatment
| Medicine |
Diluted indocyanine green (ICG) solution will be directly injected into the bile duct or gallbladder during surgery, followed by near-infrared fluorescence imaging for biliary visualization. Injection will be performed through an ENBD tube, gallbladder puncture, or biliary tube as appropriate.
