在30例成人的标本上,对十二指肠第1环状襞、十二指肠纵襞、十二指肠大乳头、肝胰壶腹及其间隔等进行解剖观测.十二指肠第1环状襞高4.86±0.36mm,厚2.85±0.17 mm,距幽门45.80±2.93mm;十二指肠纵襞出现率为76.7%;十二指肠大乳头距幽门、第1环状襞的距离分别为81.14±2.71和41.76±2.11mm,其开口处上下径和横径分别为2.88±0.17mm和2.31±0.19mm.在20例肝胰壶腹切开的标本上见肝胰壶腹间隔部分分隔(16例)和完全分隔(4例)胰胆管,间隔长度 9.30±0.46mm,共同管长度5.53±0.29mm.结果为临床内镜下顺利进行胰、胆总管造影术寻找十二指肠大乳头和插管提供了形态学依据.
In 30 adult specimens, the first ring of the duodenum 襞, longitudinal duodenum, duodenal papilla, hepatobiliary amputation and interval anatomical observation of the duodenum 1 ring 襞 height 4.86 ± 0.36mm, thickness 2.85 ± 0.17 mm, from the pylorus 45.80 ± 2.93mm; duodenal longitudinal 襞 incidence was 76.7%; duodenal large papillary from the pylorus, the first ring 襞The distance was 81.14 ± 2.71 and 41.76 ± 2.11mm, the diameter of the opening and the diameter of the opening were 2.88 ± 0.17mm and 2.31 ± 0.19mm respectively. Part of the separation (16 cases) and completely separated (4 cases) of the pancreaticobiliary duct, the interval length of 9.30 ± 0.46mm, the common tube length of 5.53 ± 0.29mm.Results For clinical endoscopic pancreas, common bile duct angiography to find the duodenum Big nipple and intubation provide a morphological basis.
