 To extend the application of ESD to superficial cancers of the esophagus, it is necessary to systematically examine the lymph nodes in the 3 fields of cervical, mediastinal, and abdominal cavities associated with a risk of metastasis. Linear endoscopic ultrasound(EUS)is superior to convex(EUS)in the depiction of the esophageal wall and its neighboring organs and is suitable for the detection of esophageal cancer. Because a longitudinal image is provided for the digestive tract, it is also effective for the retrieval of the cardiac part and the thoraco-cervical boundary. It is essential to understand the anatomical relationship of the esophagus with its surrounding organs and examine the surrounding area while confirming the index organs at each position. Because EUS can closely examine a form and internal echo pattern, it improves the quality of the diagnosis of lymph node metastasis. In addition, the systematic examination of the lymph nodes in these 3 fields leads to the early detection of metastasis and the recurrence of superficial esophageal cancer, thus extending the application of ESD.
