ABSTRACT
Objective To explore the feasibility of establishing porcine model for training of endoscopic ultrasound (EUS) guided celiac plexus paracentesis.Methods A total of 6 healthy pigs were sedated with an intramuscular injection of Ketamin at 10 mg/kg,followed by intravenous injection of 3% pentobarbital at 0.8 ml/kg.EUS was then performed and empty seeds were implanted into celiac plexus.Enhanced CT scan was performed to confirm the location of the implanted seeds.Results No animal died after the procedure.All seeds were accurately distributed on both sides of the celiac trunk except in one pig the seed was found in stomach by CT scan and was re-implanted another day.Conclusion Pigs are similar to human in anatomic structure and they can be excellent models for beginner endoscopy physicians to acquire the skill of EUS guided celiac plexus paracentesis.
