目的探讨增龄过程中咽食管(PES)管腔宽度的变化。方法运用局部解剖技术,对60例成人尸体咽食管段标本管腔进行观测。结果按形态将咽食管段管腔分紧缩型和平滑型,将咽食管段从上至下分为4个平面:环咽侧三角上缘平面、甲状软骨下角下缘平面、内腔最窄处平面和环状软骨下缘平面,从环咽侧三角上缘平面至内腔最窄处平面管腔逐渐缩窄(P<0.05),老年组管腔较中青年组及青少年组同平面管腔宽度增宽(P<0.05)。结论老年组咽食管段管腔比青少年组和中青年组均增宽,可能是老年化过程中的代偿性改变。
Objective To investigate the changes of lumen width of pharyngoesophageal (PES) during aging. Methods Local anatomy was used to observe the lumen of 60 pharyngopharyngeal specimens of adult cadaver. Results The pharyngeal esophageal segments were divided into four types according to the shape of the pharyngeal esophagus and the pharyngeal esophagus segments were divided into four planes: the upper triangular plane of the pharyngeal side, the lower flat surface of the lower thyroid cartilage, the narrowest segment The plane of the lower edge of the plane and the annular cartilage gradually narrowed from the upper triangular plane of the trochanter to the narrowest plane of the lumen (P <0.05). The lumen width of the elderly group was higher than that of the young group and the young group Wide (P <0.05). Conclusion The lumen of the pharyngoesophageal segment in the elderly group is wider than that of the young group and the middle-aged group, which may be a compensatory change in the process of aging.
