Abstract
We used endoscopic ultrasonography to observe the esophageal wall and paraesophageal collateral vessels in a case of esophageal varices, before after the two-staged combined procedure of thransthoracic esophageal transection with paraesophageal devascularization and transabdominal splenectomy with paragastric devascularization. Before the operation, esophageal varices were observed as groups of hypoechoic round vessels, and anastomosis of esophageal varices and paraesophageal veins was also observed by endoscopic ultrasonography. In the transgastric wall, short gastric veins and dilated winding splenic veins were observed. After esophageal transection, only esophageal wall thickness was observed. After an abdominal operation the short gastric veins were diminished, the splenic vein became narrow and a wall thrombus was observed. Endoscopic ultrasonography is useful for observation of the pathophysiology of esophageal varices.
