Summary
Stapler hepatectomy (SH) in laparoscopic liver resections offers reduced operative times, blood loss, and hospital stays compared to electrosurgical resections (ER). Survival and recurrence rates remain equivalent, making SH a beneficial technique.
Area of Science:
- Hepatobiliary Surgery
- Minimally Invasive Surgery
- Surgical Oncology
Background:
- Laparoscopic liver resections are increasingly performed.
- Choosing the optimal parenchymal transection technique is crucial for patient outcomes.
Purpose of the Study:
- To compare stapler hepatectomy (SH) with electrosurgical resection (ER) in laparoscopic liver surgery.
- To evaluate the impact of SH on operative outcomes, complications, and oncologic results.
Main Methods:
- Analysis of an international database of 1499 laparoscopic liver resections.
- Comparison of 764 stapler hepatectomies (SH) with 735 electrosurgical resections (ER).
- Multivariate and Kaplan-Meier survival analyses were performed.
Main Results:
- SH was associated with larger tumors, but decreased operative times, blood loss, and length of stay compared to ER.
- SH showed a trend towards higher complications, but similar bile leak rates.
- Kaplan-Meier analysis demonstrated equivalent patient survival and disease-free survival for both techniques.
- Multivariate analysis confirmed SH did not increase cancer recurrence risk.
Conclusions:
- Stapler hepatectomy offers significant advantages in reducing blood loss, transfusion needs, and operative duration.
- Despite potentially smaller margins, SH achieves comparable recurrence and survival rates to ER when adjusted for resection extent.
