Occult ischemia of the mobilized stomach is usually related to the dehiscence of an esophagogastric anastomosis. The principle of ischemic conditioning was studied to verify its clinic use. This study aims to evaluate progressively the tissue perfusion of the stomach in ischemic conditioning, establishing the best moment for gastric transposition. Twenty-four male EPM-1 Wistar rats were used, which also underwent partial desvacularization of the stomach by ligature of the left gastric vessels. Tissue perfusion was measured through flowmetry by laser Doppler (tissue perfusion unit; TPU) in the antrum (10 mm distal from the cardiac region). This measurement was done before (baseline) and immediately after the ligature, and on different postoperative days (POD) (days 3, 7, 10, and 14). A statistical analysis was done with nonparametric tests (P
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
