Summary
This study demonstrates a novel laparoscopic approach for bilateral truncal vagotomy and gastric drainage in dogs. The safe and effective procedure shows promise for future endoscopic treatments of peptic ulcer disease.
Area of Science:
- Gastroenterology
- Minimally Invasive Surgery
- Surgical Technology
Background:
- Peptic ulcer disease (PUD) remains a significant gastrointestinal condition.
- Current treatments for PUD often involve medication or invasive surgery.
- There is a need for safer, more effective endoscopic treatment options for PUD.
Purpose of the Study:
- To evaluate the feasibility and safety of a combined thoracoscopic and laparoscopic technique for bilateral truncal vagotomy and gastric drainage.
- To assess the efficacy of a contact Nd:YAG laser fiber in performing the vagotomy.
- To determine the potential for this approach as a precursor to endoscopic PUD treatment.
Main Methods:
- Bilateral truncal vagotomy and gastric drainage were performed in five mongrel dogs.
- The procedure utilized standard laparoscopic instruments, including a transthoracic thoracoscopic approach for vagotomy and a transperitoneal laparoscopic approach for pyloromyotomy.
- A contact Nd:YAG laser fiber was employed for the vagotomy.
Main Results:
- The surgical procedure resulted in no mortality and minimal post-operative morbidity.
- Pathologic examination confirmed complete vagotomy in all subjects.
- Post-operative gastric emptying was assessed as satisfactory.
Conclusions:
- The described laparoscopic and thoracoscopic technique for bilateral truncal vagotomy and gastric drainage is safe and effective in a canine model.
- The use of a contact Nd:YAG laser fiber is viable for achieving complete vagotomy.
- This study represents a potential first step towards developing a simple, safe, and effective endoscopic procedure for peptic ulcer disease treatment.
