Summary
Monopolar electrosurgery is superior to neodymium:YAG laser for gallbladder dissection during laparoscopic cholecystectomy, offering reduced blood loss and dissection time. This study provides key comparative data for surgical instrument selection.
Area of Science:
- Minimally Invasive Surgery
- Surgical Technology
- Gastrointestinal Surgery
Background:
- Optimal surgical instruments for gallbladder dissection during laparoscopic cholecystectomy remain debated.
- Limited prospective comparative data exists for evaluating different dissection techniques.
Purpose of the Study:
- To prospectively compare the efficacy and safety of contact neodymium:YAG laser versus monopolar electrosurgical dissection for gallbladder removal.
- To provide comparative data to guide the selection of surgical instruments in laparoscopic cholecystectomy.
Main Methods:
- A prospective randomized trial involving 100 patients undergoing laparoscopic cholecystectomy.
- Comparison between contact neodymium:YAG laser (15 W) and monopolar electrosurgery (25 W coagulation) for gallbladder dissection.
- Data collection included dissection time and estimated blood loss.
Main Results:
- Mean gallbladder dissection time was shorter with electrosurgery (19.2 min) compared to laser (23.6 min).
- Estimated blood loss was significantly lower in the electrosurgery group.
- Laser malfunction or fiber fragmentation occurred in six cases, requiring conversion to electrosurgery.
Conclusions:
- Monopolar electrosurgery demonstrates significant advantages over the neodymium:YAG laser for gallbladder dissection in laparoscopic cholecystectomy.
- Electrosurgery offers improved efficiency and reduced blood loss, enhancing patient safety during the procedure.
