Abdominal radiographs are used to determine the location of the tip of a newly placed nasogastric tube. The precise location of the gastroesophageal junction has not been well described in the radiology literature.
To improve interpretation of radiographs taken to evaluate the location of the tip of a nasogastric tube. Using UGI barium studies, we determined the anatomical location and variability of the position of the gastroesophageal (GE) junction and the pylorus
We reviewed 200 upper gastrointestinal barium studies (50 in each of 4 age groups). We measured the vertebral levels and distance of the gastroesophageal junction and the pylorus from the spine, the vertical distance of the gastroesophageal junction from the dome of the diaphragm and the distance from the gastroesophageal junction to the pylorus.
There is a constant location of the GE junction with no significant variation between age groups. There is a moderately constant location of the pylorus. The other measurements were very variable.
The location of the GE junction is very constant, irrespective of age. Tube tips below the level of the vertebral disc between the 11th and 12th thoracic vertebra and/or more than 16 mm from the left side of the spine lie in the stomach and not the lower esophagus. Our results should help in accurate radiographic description of the location of the tip of an NG tube.
腹部 X 光片用于确定新插入的鼻胃管尖端的位置。胃食管交界处的准确位置在放射学文献中尚未得到很好的描述。
为了提高对评估鼻胃管尖端位置的 X 光片的解读。我们使用 UGI 钡研究，确定了胃食管（GE）交界处和幽门的解剖位置和位置变化。
我们回顾了 200 例上消化道钡剂研究（每组 50 例）。我们测量了胃食管交界处和幽门与脊柱的椎体水平和距离、胃食管交界处与膈肌穹顶的垂直距离以及胃食管交界处与幽门的距离。
GE 交界处的位置恒定，不同年龄组之间没有明显差异。幽门的位置相对恒定。其他测量值变化很大。
GE 交界处的位置非常稳定，与年龄无关。位于第 11 和第 12 胸椎之间的椎间盘水平以下的管尖和/或距脊柱左侧超过 16 毫米的管尖位于胃中，而不是下段食管。我们的结果应该有助于准确描述 NG 管尖端的位置的放射学描述。
