[Basic studies of ultrasound surgery. VIII. Experimental animal studies of power ultrasound surgery of the swine pancreas].
The technique of the power ultrasound was tested in vitro and in vivo in 20 porcine pancreas. Simultaneous temperature measurements and laboratory tests do not produce any restriction. Enzymatic disorders were provable adequate to the clinical course. The ultrasonic effect guarantees a nearly riskless dissection in the layer. Joining processes, by adding Ligament-FIMOMED, produced a waterproof occlusion of parenchymal wounds. The cross-section of the pancreas with the pancreatic duct was sealed sufficiently. Also the jointed pancreato-jejunostomy remained sufficient. The reaction of the pancreatic parenchyma to the power ultrasound was small. A scarred metaplasia evolved immediately at the adhesive as a chronic atrophic interstitial pancreatitis. Only in case of occlusion of the pancreatic duct this alteration comprehended the whole pancreas.
