摘　　要：目的研究成人尸体阑尾的大体表现及变异,为阑尾影像研究提供依据。方法应用大体解剖学测量方法研究31例尸体阑尾的形态、位置、大小、及走行。结果31具标本均见阑尾,表现为管状或蚓状盲管,18例(18/31,58%)粗细均匀,13例(13/31,42%)远段增粗。阑尾根部27例(27/31,87.1%)位于盲肠后内,4例(4/31,12.9%)位于盲肠尖端,至盲肠尖端的距离为0.1～5.9 cm,距回盲瓣距离为0.7～3.5 cm,17例(17/31,54.8%)阑尾位于回肠末端前,14例(14/31,45.2%)位于回肠末端后。阑尾长度为1.5～8.9 cm,直径为4～7 mm。结论多数成人阑尾形态、位置比较固定,其长度、管径变异小,走形方向虽存在一定的变异,但多数阑尾可通过规范的影像学检查得以显示。Objective To study the appearance and variation of the vermiform appendix and to provide anatomical basis for clinical imageology. Methods The morphology, location, size and direction variation of appendix were observed in 31 corpses by gross anatomy . Results The appendix was present in all 31 corpses with a short caecus or a earthworm-like caecus, even diameter in 18 （18/31, 58%） corpses, the distal segment hypertrophied in 13 （13/31, 42%） corpses. The root of the appendix located at the posterior wall of the caecum in 27 （27/31, 87.1%） corpses, at the top of the caecum in 4 （4/31,12.9%） corpses. The distance between the appendix and the top of caecum was 0.1-5.9 cm, between the appendix and ileoceal valve was 0.7-3.5 cm. The direction variation of appendix was ante-terminal ileum in 17 （17/31, 54.8%） corpses, poster- terminal ileum in 14 （14/31, 45.2%） corpses. The length and diameter of the appendix were 1.5-8.9 cm, 4-7 mm. Conclusions The majority appendix has invariable morphous, fixed location, mild diversitary length and diameter, although has some extent direction variation, the majority appendix could be present clearly by normative imageology examination.
