研究概览

简要总结

To analyze the differences between treatment groups [standard dose of 2.5 mg administered >3 hours preoperatively vs. reduced dose (0.25 mg) administered immediately preoperatively (15 minutes)], during laparoscopic cholecystectomy (LC), in terms of:

Visualization of extrahepatic biliary structures. Degree of visualization of these structures. Degree of background hepatic fluorescence disturbance. Perceived utility of the technique across treatment groups.

入选标准

  • Adult patient (≥18 years old) who is able to understand and sign the informed consent form.
  • Indication for: a) Elective laparoscopic cholecystectomy (LC) due to: Symptomatic cholelithiasis (history of biliary colic, acute calculous cholecystitis, choledocholithiasis, ascending acute lithiasic cholangitis, or acute biliary pancreatitis); Gallbladder polyps with indication for laparoscopic surgery. b) Early LC indication (<72 hours from hospital admission) for: Acute calculous cholecystitis; Acute acalculous cholecystitis; Complicated biliary colic. c) Indication for delayed emergency LC.

排除标准

  • Pregnancy or breastfeeding.
  • Chronic kidney disease (Stage > IIIb).
  • History of adverse reactions or allergies to indocyanine green (ICG).
  • Confirmed adverse reactions or allergies to iodinated contrast agents.
  • Functional thyroid disorders (e.g., hyperthyroidism, thyroiditis, toxic multinodular goiter, functioning thyroid adenoma).
  • Non-deferrable/emergency gallbladder surgery.
  • Primary open (laparotomic) cholecystectomy.
  • Preoperative suspicion of gallbladder carcinoma.
