Summary
This study introduces a new, minimally invasive approach for liver surgery using single-incision laparoscopy combined with radiofrequency pre-coagulation. The technique proved safe and effective for minor hepatectomy, achieving good outcomes with minimal complications.
Area of Science:
- Hepatobiliary Surgery
- Minimally Invasive Surgery
- Surgical Oncology
Background:
- Single-incision laparoscopy (SIL) aims to reduce surgical trauma but faces challenges in bleeding control for hepatectomy.
- A novel strategy combining inline radiofrequency pre-coagulation with transumbilical SIL is proposed for liver resection.
Purpose of the Study:
- To evaluate the safety and efficacy of a novel transumbilical single-incision laparoscopy (SIL) hepatectomy technique.
- To assess bleeding control, postoperative complications, and resection margin status in patients undergoing SIL hepatectomy.
Main Methods:
- A cohort of 21 patients underwent transumbilical SIL hepatectomies (segments II-VI) using inline radiofrequency pre-coagulation (Habib 4X) for hepatic transection.
- Outcomes measured included bleeding control, complications, and resection margins in malignant cases.
Main Results:
- SIL hepatectomy was successfully completed in all patients, with a mean resection time of 66 minutes.
- No substantial blood loss occurred, and no additional instruments were needed for bleeding or bile control.
- One postoperative complication (pleural effusion) was noted. Resection margins were free in 92.31% of malignant cases, with zero 90-day mortality.
Conclusions:
- The combination of SIL and inline radiofrequency pre-coagulation is a simple, effective, and safe method for minor hepatectomy.
- This technique offers a promising solution for reducing surgical trauma in liver resections while maintaining oncological safety.
