    • Abstract:
      Background: Intrahepatic bile duct stones, although common and benign, require varying therapeutic strategies due to their recurrent nature. Inadequate management can escalate to liver cirrhosis or cholangiocarcinoma. A surgical method merging indocyanine green fluorescence imaging (ICG-FI) with liver cone unit resection is optimal, ensuring complete lesion removal and healthy liver tissue conservation. Method: A retrospective descriptive study was conducted on 15 patients with intrahepatic bile duct stones who were admitted to Sichuan Provincial People's Hospital from January 2021 to December 2023. All patients underwent laparoscopic anatomical liver resection guided by ICG-FI. Results: Among the 15 patients included in the study, ten were male and five were female, with an average age of 52 years. All patients were free from underlying medical conditions. Intraoperatively, ICG-FI was good, with clear boundaries, and all patients successfully underwent surgery without any conversions to open surgery. The mean operative time was 236 ± 56 min, and the estimated blood loss was 320 ± 75 ml. Patients had a postoperative hospital stay of 5.5 ± 1.5 days. No severe complications occurred. Conclusions: Real-time ICG-FI with anatomical liver resection is a safe and effective approach for managing intrahepatic bile duct stones. [ABSTRACT FROM AUTHOR]
