A pig model for advanced laparoscopic biliary procedures.
Advanced laparoscopic biliary procedures can be undertaken in a pig model, but the small size of the normal common bile duct makes learning difficult. We have developed a prepared pig model of common bile duct ligation on which to practice advanced laparoscopic biliary surgery. The pig's distal common bile duct was occluded using several different methods via a minilaparotomy. Laparoscopic biliary procedures were undertaken 6-21 days later. The common bile duct became dilated to between 2 and 3 cm in diameter in all cases, and this was well tolerated by the animals. All advanced laparoscopic biliary procedures were possible, including choledochoscopy, exploration of the bile duct, and cholecystojejunostomy. Short-term common bile duct ligation is well tolerated in pigs and can be used to create a model for practicing advanced laparoscopic biliary procedures.
