食管长度的研究,在临床应用上頗为重要。內經上記载:“由咽门至胃一尺六寸”,但我們手里現有的文献,未见近世国人食管长度的研究資料。在一般教科书的記载,完全是用公分或英时計算,而所記載的数字极不一致,且最长与最短之間距离頗大。張岩記载成年人由门齿到賁门为40——45公分,Boyd,Brash及Tohnston,D.whillis等記载由門齿到賁門为15——16英时,Rawber-Kopsch記載由环状軟骨至胃28——30公分。Morris記載食管长23——30公分。乳儿食管长11——16公分,2岁儿童食管长20公分,年长儿童食管长25——32公分。上述記载,均有一定事实根据。但因人体高低不
Esophageal length of the study, in clinical application is quite important. The Book of Merit reads: “From the pharynx to the stomach a foot six inches”, but the existing literature in our hands, no esophageal length of the study data. In the general textbook records, the total is calculated using centimeters or English hours. The figures recorded are extremely inconsistent and the distance between the longest and the shortest is quite large. Zhang Yan recorded from the incisors to the cardia for adults 40--45 cm, Boyd, Brash and Tohnston, D. Whillis and other records from the incisors to the cardia for 15-16 mouth, Rawber-Kopsch records by the ring Cartilage to the stomach 28 - 30 cm. Morris records esophagus length 23--30 cm. Esophageal long 11--16 cm, esophageal 20-year-old children 20 cm, 25-32 cm of elderly children with esophageal length. The above records, all have some factual basis. But because of the human body is not high or low
