Elemental diet and bile induced pancreatitis.
The effectiveness of an elemental diet was investigated as both a prophylactic and therapeutic agent in experimental canine pancreatitis. Pancreatitis was induced by operative injection of a bile -saline solution mixture under pressure retrograde into the main pancreatic duct. In addition to a preinjection control sample, serial biopsies were obtained at 30 minute intervals for 90 minutes after injection and fixed for light and electron microscopic examinations. In addition, preoperative and postoperative blood samples were drawn and analyzed for amylase. After operation, half of the dogs from each original group were fed Vivonex-100, the other half from each group, regular laboratory chow, yielding four ultimate groups based on preoperative and postoperative diets. Successful induction of pancreatitis was evaluated by the difference between preoperative and postoperative amylase values, all of which were significant by group at the p less than 0.01 level. No ultrastructural evidence was found for the modification of zymogen granules with the pretreatment elemental diet nor were differences evident, histologically or ultrastructurally, in the severity of pancreatitis between the pretreated and nonpretreated groups. Finally, gross mortality figures demonstrated no efficacy of elemental diet for pretreatment prophylaxis of acute pancreatitis.
