Summary
The Curettage and Aspiration Dissection Technique (CADT) using Peng's Multifunction Operative Dissector (PMOD) offers effective liver resection with zero intraoperative bleeding and mortality. This innovative method shows promise for hepatic surgery.
Area of Science:
- Hepatobiliary Surgery
- Surgical Innovation
- Electrosurgery
Background:
- A novel dissection technique, Curettage and Aspiration Dissection Technique (CADT), was developed for liver resection.
- This technique utilizes Peng's Multifunction Operative Dissector (PMOD), an electrosurgical device integrating cutting, coagulation, aspiration, and dissection.
Purpose of the Study:
- To evaluate the efficacy and safety of the CADT technique and the PMOD device in hepatic surgery.
- To assess the performance of CADT and PMOD in various liver resection procedures.
Main Methods:
- A consecutive series of 70 patients undergoing segmentectomy or major hepatectomy from June 2005 to December 2006 were included.
- The CADT technique was performed by a single surgeon using the PMOD device.
- Peri-operative data and technical aspects were summarized.
Main Results:
- Forty-nine patients had varying degrees of cirrhosis.
- Median blood loss was 470 ml (range: 100-2400 ml).
- Zero intraoperative bleeding and zero mortality within one month postoperatively were observed.
- Postoperative complications included bile leak (5 cases), pleural effusion (9 cases), and ascites (6 cases), with no CADT-related complications.
Conclusions:
- The CADT technique and PMOD device demonstrate superior dissection and hemostasis capabilities in liver surgery.
- CADT and PMOD represent a valuable alternative to existing devices for hepatic resections.
