“…If anastomotic stricture can be caused by poor blood supply at the anastomosis site, then this result stands to reason and prostaglandin E 1 administration, which has been proven for the augmentation in the microcirculation of the gastric tube, might prevent minor anastomotic leakage or anastomotic stricture when the surface temperature of proximal gastric tube is relatively low. 24 Although this preliminary study was conducted in a small number of patients and therefore requires a larger number of cases to predict a minor anastomotic impairment, thermal imaging can at least predict gastric tube necrosis. Since the thermal imaging system is an easy, sensitive, rapid, and noninvasive method with a high reproducibility in detecting gastric viability after devascularization or gastric tube construction, the practical application of thermal imaging systems may therefore be become a valuable technique for the reliable determination of gastric tube viability.…”
