Summary
In rabbit laparoscopic cholecystectomy, both electrothermal bipolar vessel sealing (EBVS) and bipolar Maryland dissection are equally safe and effective for gallbladder removal. Further research is needed for gallbladder pathologies.
Area of Science:
- Veterinary Surgery
- Minimally Invasive Procedures
- Comparative Surgical Techniques
Background:
- Laparoscopic cholecystectomy (LC) is the standard surgical treatment for gallbladder disease in small animals.
- Evaluating different dissection tools is crucial for optimizing LC outcomes.
Purpose of the Study:
- To compare the efficacy of electrothermal bipolar vessel sealing (EBVS-LigaSure) versus standard bipolar Maryland dissection for gallbladder dissection during LC in rabbits.
- To assess the impact of these dissection methods on liver function tests, macroscopic findings, histopathology, and bacteriology.
Main Methods:
- Twenty rabbits underwent LC, divided into two groups (n=10 each).
- Group 1 (GLL) used EBVS for gallbladder dissection and cystic duct sealing.
- Group 2 (GLE) used bipolar dissecting forceps for dissection and EBVS for cystic duct sealing.
Main Results:
- Group GLL showed higher alkaline phosphatase levels 15 days post-surgery compared to Group GLE.
- Group GLE exhibited higher alanine aminotransferase levels at day 3 compared to Group GLL.
- No significant statistical differences were found in overall safety and efficacy between the two dissection methods.
Conclusions:
- Both EBVS and bipolar Maryland dissection are equally safe and effective for laparoscopic cholecystectomy in rabbits.
- Further clinical studies are warranted to evaluate these devices in animals with gallbladder pathologies.
