Summary

This study tests whether a dye called indocyanine green (ICG), which makes bile ducts glow under special cameras, can reduce bile duct injuries and leaks during emergency gallbladder removal. About 296 adults with acute cholecystitis (inflamed gallbladder) will be randomly assigned to have surgery with or without the dye. The goal is to see if the dye helps surgeons avoid complications, leading to safer outcomes.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥ 18 years. * Diagnosis of acute cholecystitis according to Tokyo Guidelines (TG18) criteria. * Planned urgent/emergency laparoscopic cholecystectomy during the index admission, as determined by the treating surgical team. * Ability to provide written informed consent prior to surgery. Exclusion Criteria: * Known hypersensitivity or contraindication to indocyanine green (ICG) or its excipients. * Pregnancy or breastfeeding. * Clinical situation preventing protocol implementation or informed consent (e.g., life-threatening emergency requiring immediate surgery without time for study procedures). * Primary open cholecystectomy planned (i.e., not intended laparoscopic approach). * Any condition that, in the investigator's opinion, makes participation unsafe or not feasible.
