Fluorescence-Guided Laparoscopic Regional Anatomical Subsegmental Liver Resection Combined with Cholecystectomy...

Area of Science:

• Hepatobiliary Surgery
• Minimally Invasive Surgery
• Surgical Oncology

Background:

• Laparoscopic hepatectomy is crucial for liver disease treatment.
• Achieving precise tumor resection with negative margins and parenchyma preservation is challenging.
• The Laennec's capsule approach aids dissection and anatomical hepatectomy.

Purpose of the Study:

• To evaluate a combined technique for laparoscopic hepatectomy.
• To improve precision and safety in liver tumor resection.
• To assess the efficacy of Laennec's capsule dissection with ICG fluorescence guidance.

Main Methods:

• A novel approach combining Laennec's capsule dissection and indocyanine green (ICG) fluorescence guidance was employed.
• Gallbladder removal via Laennec capsule, followed by pedicle dissection (segments 5 and 6).
• Hepatectomy performed using fluorescence imaging and ischemic demarcation lines.

Main Results:

• The combined technique facilitated precise hepatectomy.
• The patient experienced an uneventful recovery, discharged on postoperative day five.
• The method demonstrated safety and effectiveness for tumor resection.

Conclusions:

• The combination of ICG fluorescence and Laennec's capsule approach is a safe and effective strategy.
• This technique enhances precision in laparoscopic hepatectomy.
• It offers a valuable solution for challenging liver resections.
