SOME PATTERNS OF CHANGES IN THE LYMPHOCIRCULATORY SYSTEM OF THE INTESTINE AFTER GASTRIC RESECTION
Abstract
The present study investigates morphological and histochemical changes in the lymphocirculatory system of the small intestine following various types of gastric resection in dogs. A total of 122 dogs were examined, including 104 that underwent gastric resection using different methods (Billroth I, Kupriyanov-Zakharov, Hofmeister-Finsterer, and Polna-Reichel) and 18 in the control group. Structural transformations of lymphatic capillaries and vessels were analyzed over different postoperative periods ranging from 3 days to 1 year. Significant alterations were observed in the mucosal lymphatic network, including capillary dilation, new anastomoses, and wall protrusions. Pathohistological examinations revealed edema, infiltration by lymphocytes and plasma cells, deformation of villi and crypts, and epithelial atrophy. These changes were most prominent in the early postoperative period, with partial recovery and adaptation over time. The findings highlight compensatory remodeling of intestinal lymphatic vessels aimed at restoring microcirculation and lymphatic drainage under conditions of venous stasis and interstitial edema caused by surgical trauma.
