This study aimed to demonstrate the distal end of the oesophagus using a transabdominal ultrasound technique (TUS) and to measure the normal oesophageal wall thickness in adults. 65 patients without oesophageal disease and 38 normal volunteers were examined by TUS. A left subcostal approach was used to demonstrate the oesophagus. The wall thickness and length were measured in both the supine and 45 degrees right side up oblique (RUO) positions. The abdominal oesophagus was visualized in 80% of patients in the supine position and 92% in the RUO position. Satisfactory demonstration was obtained in 67% of patients in the supine and 85% in the RUO position. The oesophageal wall thickness averaged 2.8 mm (range 2.0-4.0 mm, SD 0.7 mm). The visualized length in these subjects averaged 2.3 cm in the supine position and 3.0 cm in the RUO position, which included approximately 1.5 cm of the lowest portion of the thoracic oesophagus in addition to the abdominal oesophagus. TUS can demonstrate the abdominal oesophagus in the majority of patients and has the potential to provide information on disorders of structure and motility.
本研究旨在采用经腹超声技术（TUS）显示食管远端，并测量成人正常食管壁厚度。对65例无食管疾病的患者和38名正常志愿者进行了TUS检查。采用左肋下途径显示食管。在仰卧位和右侧45度斜卧位（RUO）测量食管壁厚度和长度。在仰卧位，80%的患者可观察到腹部食管，在RUO位为92%。在仰卧位，67%的患者显示满意，在RUO位为85%。食管壁厚度平均为2.8mm（范围2.0 - 4.0mm，标准差0.7mm）。这些受试者在仰卧位的可视长度平均为2.3cm，在RUO位为3.0cm，除腹部食管外，还包括约1.5cm的胸段食管最低部分。TUS可在大多数患者中显示腹部食管，并有潜力提供有关结构和动力障碍的信息。
