Summary
Vascular staplers offer a safe and rapid method for transecting hepatic veins and Glisson
Area of Science:
- Hepatobiliary Surgery
- Surgical Oncology
- Vascular Anastomosis
Background:
- Anatomical liver resection necessitates the transection of critical vascular and biliary structures.
- Precise and safe transection of hepatic veins and Glisson's pedicle is crucial for minimizing intraoperative complications.
Purpose of the Study:
- To evaluate the safety and efficacy of endovascular staplers for transecting hepatic veins and Glisson's pedicle during anatomical liver resection.
- To assess the outcomes and complication rates associated with using endovascular staplers in hepatectomy procedures.
Main Methods:
- Retrospective analysis of surgical records from 25 patients undergoing hepatectomy.
- Utilization of endovascular staplers (35 and 60 mm) for transecting hepatic veins (n=25) and Glisson's pedicle (n=8).
- Inclusion of various hepatectomy types: left lateral sectorectomy, right lateral sectorectomy, right hepatectomy, left hepatectomy, and trisegmentectomy.
Main Results:
- Endovascular stapling was successfully employed in all hepatic vein transections and 8 Glisson's pedicle transections.
- No stapler firing failures were observed during the cutting process.
- One case of aberrant bile duct injury occurred; however, no instances of bleeding or bile leakage from transected sites were reported.
Conclusions:
- Endovascular stapling provides a safe and rapid technique for vascular and pedicle transection in anatomical liver resections.
- This method demonstrates a low complication rate, facilitating efficient hepatectomy procedures.
