Summary
Laennec's approach is a safe and effective method for laparoscopic anatomical hepatectomy (LAH). Utilizing Laennec's capsule aids in standardizing surgical techniques for this complex liver procedure.
Area of Science:
- Hepatobiliary Surgery
- Minimally Invasive Surgery
- Surgical Anatomy
Background:
- Laennec's capsule has been known for approximately 200 years.
- Laparoscopic anatomical right and left hemihepatectomy (LARH and LALH) using Laennec's approach are infrequently documented.
Purpose of the Study:
- To evaluate the safety and feasibility of Laennec's approach for laparoscopic anatomical hepatectomy (LAH).
- To assess the utility of Laennec's capsule in standardizing LAH procedures.
Main Methods:
- Retrospective analysis of 15 patients undergoing LAH via Laennec's approach (May 2017 - July 2020).
- Detailed recording and analysis of operative time, blood loss, postoperative complications, and hospital stay.
- Histological confirmation of Laennec's capsule presence.
Main Results:
- Laennec's approach was successfully used for LAH in all 15 patients without conversion to open surgery.
- Indications included hepatic hemangioma (4), hepatolithiasis (2), and primary liver cancer (9).
- Mean operative time: 193 min, blood loss: 247 mL, hospital stay: 8.7 days; no mortality, bile leakage, or bleeding.
Conclusions:
- Laennec's approach is a safe and feasible technique for laparoscopic anatomical hepatectomy.
- Accurate identification of Laennec's approach, guided by Laennec's capsule, can standardize surgical techniques for LAH.
