Abstract
We reported on our operation techniques for esophageal achalasia and hiatal hernia. At the same time, we outlined the practice of intraesophageal pressure, pH determination and endoscopic ultrasonography (EUS), and further, the relation between the results of these determinations and postoperative follow-up in this diseases. The results of EUS for esophageal achalasia showed a thick hypoechoic fourth layer. We classified the degree of muscular hypertrophy in achalasia into three levels.
Hiatal hernia was represented as a hypoechoic mass in the third and fourth layers of the esophageal wall, and it was classified into three types.
Therefore, we concluded that EUS is a useful examination method in patients with esophageal achalasia and hiatal hernia.
