Radiological and macroscopic evaluations of the pancreatic efferent ducts were performed in pigs. The examinations were conducted on 280 pancreas. Two hundred glands were collected from pigs in the slaughter-house and examined with the use of preparation and microscopic evaluation techniques. A contrast radiological examination by means of 60% Urapolium Polfa was conducted with 50 isolated glands, and in 30 cases in situ during operative procedure the evaluation of the efferent ducts was made. In the majority of the examined pancreas, one centrally situated duct of the right lobe and two ducts of the left lobe joined together were found. The efferent ducts of the right and the left lobe were joined in all examined pancreatic glands near the base of the pancreas corpus into one centrally situated pancreatic additional duct (ductus pancreaticus accesorius) which opens independently into the duodenum at the duodenal papilla minor.
The following paper deals with the results of a long-lasting cannulation of the porcine pancreas performed using new methods. One method is based on a direct cannulation of the pancreatic duct after its incision. The other (designed by the authors) consists of a cannulation of the pancreas through the minor duodenal papilla. During the 14-day experimental period the efficiency of both methods was evaluated based upon certain indexes of the pancreatic juice secretions, including the level and daily dynamics of the secretions, as well as individual differentiations within two experimental groups. The method of cannulation through the minor duodenal papilla gave better results and a higher efficiency of the secretion, thus it was found to be more advantageous than the cannulation of the pancreatic duct after its incision.
Laparocholecystectomy was done on 4 cross-breed Large-White pigs, males and females of 20 kg b.w. under halotan general anesthesia. Peritoneal emphysema was created by carbon dioxide at a pressure of 10-12 mm Hg. The operation was performed using trocars of different diameters in four accesses. Biliary ductule and artery were closed by titanic staplers Endoclip TM - Auto Suture and then ruptured. There were no complications during the operation and in the post-operation phase. After the operation pigs woke up in a few hours and after 24 h they were fed balanced nutritional doses which were increased as body weight increased. After 5 months pigs gained 110-115 kg b.w. Laparocholecystectomy reduces operation trauma and enables quick recovery. The four spot peritoneal access made by trocar eliminates the possibility of many postoperative complications that could develop after classical laparotomy with a long abdominal incision.
