LIVE INVESTIGATION OF THE INTESTINAL LYMPHATIC SYSTEM FOLLOWING GASTRIC RESECTION
Main Article Content
Abstract
This study explores the impact of gastric resection on the lymphatic system of the small intestine with respect to fat absorption. The authors conducted a vital investigation of intestinal lymphatic vessels in 34 dogs using a biological injection method. It was found that under normal conditions, fat absorption occurs predominantly in the duodenum and proximal small intestine. However, after gastric resection, this process is disrupted and shifts to the terminal sections of the small intestine and, in some cases, even to the large intestine.
This displacement was particularly pronounced after gastroenterostomy procedures performed using the Polya–Reichel method. Under such conditions, the lymphatic system of the large intestine acquired the ability to absorb fats—an uncharacteristic function under normal physiological conditions. These findings highlight the high compensatory and adaptive capacity of the intestinal lymphatic system during the postoperative period.
