Summary
Combining ultrasonic dissector (UD) and harmonic scalpel (HS) for liver resection safely reduces blood loss and complications. This method, while increasing operative time, offers significant patient benefits compared to traditional techniques.
Area of Science:
- Hepatobiliary Surgery
- Surgical Technology
- Minimally Invasive Procedures
Background:
- Hepatic resection traditionally involves significant blood loss and potential complications.
- Evaluating novel energy devices for improved surgical outcomes is crucial in liver surgery.
Purpose of the Study:
- To assess the feasibility and effectiveness of combining ultrasonic dissector (UD) and harmonic scalpel (HS) in hepatic resection.
- To compare surgical outcomes of UD + HS technique with the clamp crushing method.
Main Methods:
- A prospective study involving 100 patients undergoing liver resection with UD + HS (January-December 2004).
- UD used for parenchyma dissection; HS for vessel sealing.
- Comparison with 100 patients using the clamp crushing method.
Main Results:
- The UD + HS group showed significantly reduced blood loss (500 vs 700 ml), fewer transfusions (22 vs 39), less tumor exposure (4 vs 12), and shorter hospital stay (7 vs 8.5 days).
- Major complications, including fluid collection and biliary fistula, were less frequent (2 vs 9).
- Operative time was longer in the UD + HS group (385 vs 330 minutes).
Conclusions:
- Combined use of UD and HS is a safe and effective technique for hepatic resection.
- This approach offers advantages in reducing blood loss and surgery-related complications.
- A potential drawback is the increased operative time.
