Summary
Total pancreatectomy using a Nd:YAG laser was faster and safer in pigs than dogs. Pig pancreatic anatomy closely resembles human anatomy, suggesting pigs as a suitable model for pancreatic research.
Area of Science:
- Veterinary Surgery
- Surgical Technology
- Comparative Anatomy
Background:
- Total pancreatectomy is a complex surgical procedure.
- Evaluating novel surgical techniques and animal models is crucial for advancing surgical practice.
Purpose of the Study:
- To compare the feasibility and outcomes of total pancreatectomy using a contact Nd:YAG laser in dogs and pigs.
- To assess the anatomical similarities between pig and human pancreatic structures.
Main Methods:
- Total pancreatectomy was performed in dogs (n=5) and pigs (n=6) utilizing a contact Nd:YAG laser (1060 nm wavelength) with a sapphire tip.
- Surgical parameters included 10-12 W power and a 9.9 s pulse time.
- Animals were monitored for one week postoperatively for complications.
Main Results:
- Total pancreatectomy was significantly faster in pigs than in dogs (P < 0.001).
- Pigs exhibited significantly fewer ligatures (P < 0.05) and less bleeding (P < 0.05) compared to dogs.
- No mortality, infection, or other complications were observed in either group during the follow-up period.
Conclusions:
- Total pancreatectomy with a contact Nd:YAG laser is more efficient and safer in pigs than in dogs.
- The anatomical resemblance of the pig pancreas to human anatomy makes it a valuable model for studying pancreatic diseases and surgical procedures.
