本文对32具成人尸体的十二指肠形态、位置、长度和管径的观测结果:十二指肠的基本形态呈“C”形,但按其下曲、下部的明显程度,又可将十二指肠分为三种形态,即:四部均显型;下曲下部不显型;有下曲而下部不显型。十二指肠的总长度为(X± S)24.83±4.83cm;十二指肠各部的长度为(X±S):上部5.28± 1.71cm;降部8.55± 1.40cm;下部6.08± 0.79cm;升部4.46± 0.70cm。十二指肠的管径为(X±S) 2.95±0.63cm。
In this paper, 32 adult cadaver duodenum morphology, location, length and diameter of the observation results: the basic form of the duodenum was “C” shape, but according to the next song, the lower the extent of the obvious, but also The duodenum is divided into three forms, namely: four are obvious type; the lower part of the song is not obvious type; the lower song and the lower part is not significant. The total length of the duodenum was (X ± S) 24.83 ± 4.83 cm; the length of each part of the duodenum was (X ± S): 5.28 ± 1.71 cm in the upper part; 8.55 ± 1.40 cm in the lower part; 6.08 ± 0.79 cm in the lower part ; Ascending 4.46 ± 0.70cm. Duodenal diameter (X ± S) 2.95 ± 0.63cm.
