Summary
Laparoendoscopic single-site hepatectomy (LESH) is a safe and feasible minimally invasive liver surgery. It shows no significant difference in stress responses compared to traditional laparoscopic hepatectomy (LH).
Area of Science:
- Minimally Invasive Surgery
- Hepatobiliary Surgery
- Surgical Innovation
Background:
- Laparoendoscopic single-site hepatectomy (LESH) is an emerging technique.
- Laparoscopic hepatectomy (LH) is a standard minimally invasive approach.
- Comparative studies on LESH and LH stress responses are limited.
Purpose of the Study:
- To evaluate the technical feasibility of LESH.
- To compare the surgical outcomes and stress responses between LESH and LH.
- To assess LESH as a potential alternative in clinical practice.
Main Methods:
- A prospective controlled trial involving 30 female pigs.
- Random assignment to either LESH or LH groups.
- Measurement of operative time, blood loss, complications, and stress indicators (adrenaline, cortisol, IL-1, IL-6, WBC).
Main Results:
- LESH was technically feasible with one conversion to LH.
- No significant differences were observed in operative time, blood loss, or complication rates between LESH and LH.
- Both groups exhibited similar trends in stress indicators postoperatively.
Conclusions:
- LESH is a safe, feasible, and minimally invasive liver resection technique.
- LESH demonstrates comparable stress responses to conventional LH.
- LESH may be a viable option for experienced laparoscopic surgeons.
