[The effect of two different methods of jejunal feeding on pancreatic function].
Pancreatic juice was continuously diverted from the Wirsungial duct by nasopancreatic drainage of the remnant of the gland after pylorus preserving partial pancreato-duodenectomy in 14 patients. On the 7th postoperative day with stabilized pancreatic secretion the juice was collected in 10 min fractions, while interdigestive secretory phases of the parenchyma were established by volume changes. At the beginning of a phase 100 ml slightly hyperosmolar (400 mosmol/L) oligopeptide diet with 90 kcal was given as a bolus injection for 7 patients or 60 min infusion into the second jejunal loop by fine needle catheter jejunostomy for 7 patients also. Pancreatic water, bicarbonate, protein, chymotrypsin, amylase levels peak, and integrated secretory responses were measured. It was observed, that infusion of the diet did not disturb cycling interdigestive phases and did not increase peak and integrated outputs. Bolus administration interrupted interdigestive phases and stimulated pancreatic water, bicarbonate, protein, chymotrypsin and amylase outputs nonparallelly. On the basis of their data authors concluded, that pancreatic secretion seems to be well preserved without duodenalregulatory mechanisms; and continuous jejunal infusion feeding seems to be useful in pancreatic disease and in other postoperative states when pancreas has to be put into rest.
