Background: Blood supply to a reconstructed gastric tube after esophagectomy is mainly through the right gastroepiploic artery (RGEA); therefore, a recurrent lesion involving the RGEA is thought to be unresectable, or if possible, resectable combined with a whole gastric tube.
Methods: We developed a new method of right gastroepiploic artery occlusion test for evaluation of the blood circulation of a reconstructed gastric tube in a patient who has a recurrent lesion involving the RGEA. A balloon occlusion catheter is inserted into the RGEA through the celiac trunk through a 7 Fr angiographic catheter, and the balloon is inflated. Celiac angiography and color Doppler endoscopic ultrasonography can evaluate intragastric blood flow from the right gastric artery during occlusion of the RGEA.
Results: We present a case of successful resection of celiac lymph node metastasis invading the RGEA and the celiac trunk after esophageal reconstruction using a gastric tube.
Conclusions: When ligation of the right gastroepiploic artery is needed, the test is safe and simple to perform; and findings can be reliably evaluated by angiography and color Doppler endoscopic ultrasonography.
