Laser pancreatectomy. A comparison between dog and pig.
Total pancreatectomy was performed in dogs (n = 5) and pigs (n = 6) using a contact Nd:YAG laser with a wave length of 1060 nm. The fiber was connected to a laser scalpel, and a 1.0-mm-diameter sapphire tip was used. The power was set at 10-12 W with a pulse time of 9.9 s. The animals were followed postoperatively (p.o.) for 1 week, and no mortality, infection, or any other complication were observed. Total pancreatectomy was significantly faster to perform in pigs than in dogs (P less than 0.001). The number of ligatures (P less than 0.05) and the amount of bleeding (P less than 0.05) were significantly less in pigs than in dogs. The present paper describes the anatomy of the pancreas in dogs and pigs, and also the technical procedure of total pancreatectomy in both species is presented. In conclusion, total pancreatectomy is easier to perform in pigs than in dogs. Furthermore, the anatomy of the pancreas in the pig resembles much that in man.
