[Enteral resorption in the immediate postoperative phase following selective proximal vagotomy].
The postoperative absorption of the small intestine after selective proximal vagotomy was found out by means of the modified D-xylose absorption test in 23 patients on operating day, and on 1st, 5th, 8th, 9th and, 10th postoperative day. The constant of the adsorption speed was reduced on the operating day and decreased further to the 4th postoperative day. Afterwards the preoperative value was obtained approximately. The temporal state of the relative maximum of the curve of serum concentration (the moment tm) occurred in the same time interval. The tm-value obtained the preoperative value approximately. The dimensions of the absorption in the small intestine was reduced by 36% on the operating day, by 20,5% on the 1st postoperative day, and by 10% on the 4th postoperative day on the arithmetical average. The influence of the gastric emptying after SPV and of gastro-intestinal hormones on the process of absorption was discussed.
