【摘要】 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。更多还原

【Abstract】 Objective To investigate the changes in the lumen diameter of pharyngeal esophageal segment during the aging process. Methods The pharyngeal esophageal lumen was dissected and examined in 60 cadareric specimens.Results Pharyngeal esophageal lumen appeared in a compact or a smooth shapes. The measurement pharyngeal esophageal lumen was performed at 4 planes: lateral cricopharyngeal triangle,inferior horn of thyroid cartilage,narrowest point and inferior margin of the cricoid cartilage. It was observed that the lumen from the lateral cricopharyngeal triangle to cricoid inferior plane became gradually narrowed( P < 0. 05). The diameter of the pharyngeal esophageal lumens was greater in the elderly group than that in the youth group and the young group( P < 0. 05). There were significant differences in the lumen diameter at different planes( P < 0. 05) and in the 3 age groups( P < 0. 05). Conclusion The diameter of the pharyngeal esophageal lumens is greater in the elderly group than that in the youth group,suggesting compensatory changes in the aging process.更多还原
