Application of the Laennec approach in laparoscopic repeat liver resection

Laparoscopic repeat liver resection (LRLR) is widely recognized as an effective therapeutic option for recurrent liver disease but is challenged by extensive adhesions and altered anatomical structures resulting from previous surgeries. The Laennec approach, which leverages the unique intrahepatic membranous structure of Laennec's capsule, has emerged as a promising surgical strategy to address these technical issues. This literature review comprehensively summarizes the anatomical basis, technical evolution, clinical applications, advantages, limitations, and prospects of the Laennec approach in LRLR. By systematically organizing evidence from clinical studies, case reports, and anatomical research, this review aims to provide a comprehensive understanding of the value of the Laennec approach in overcoming the complexities of LRLR and to provide insights for its standardized application and further research.
