给“内镜肝胰壶腹括约肌切开术”、“内镜逆行胆胰管造影”和临床诊断、治疗提供解剖学基础。方法:对70例人尸体的胆总管和胰管汇合部进行了解剖、测量并统计。结果:胆总管肠壁内段长度:成人1.04±0.42cm,儿童0.89±0.35cm。胆总管人十二指肠角成人41.1±1.75°,儿童40.1±1.72°。十二指肠大乳头至胃幽门间距成人为9.84±1.58cm,儿童为8.26±1.64cm。十二指肠大乳头至上颌中切牙间距成人为74.58±1.77cm,儿童为8.26±1.64cm。胆总管和胰管汇合后共同开口有41例,占分型数50例(82％),其余为分别开口。开口处位于十二指肠降部中1/3为44例,占总例数70例(67％),其余开口于降部的上1/3或下1/3。结论:胆总管人角越小,其壁内段长度越长。胆总管和胰管汇合共同开口者占多数,十二指肠大乳头位于其降部中1/3后内侧壁者为多数,并对其临床意义展开了讨论。
To provide “Endoscopic Hepatic Ampullary Sphincterotomy”, “endoscopic retrograde cholangiopancreatography” and clinical diagnosis and treatment to provide anatomical basis. Methods: The biliary and pancreatic duct confluence of 70 human cadavers were dissected, measured and statistically analyzed. Results: The length of the common bile duct wall segment was 1.04 ± 0.42 cm in adults and 0.89 ± 0.35 cm in children. Dilator duodenum angle adult 41.1 ± 1.75 °, children 40.1 ± 1.72 °. Large duodenum to stomach pylorus spacing 9.84 ± 1.58cm adults, children 8.26 ± 1.64cm. Large duodenal to maxillary central incisor spacing was 74.58 ± 1.77 cm in adults and 8.26 ± 1.64 cm in children. Common bile duct and pancreatic duct after the merger of 41 cases, accounting for 50 cases (82%), the rest were open. In the middle of the descending part of the duodenum, there are 44 cases in the middle part of the duodenum, accounting for 70 cases (67%) in the total number of cases. The rest are open on the upper 1/3 or lower 1/3 of the descending part. Conclusion: The smaller the common bile duct angle, the longer the length of the wall segment. Common bile duct and pancreatic duct common openings accounted for the majority of large duodenal papilla in the lower part of the middle 1/3 of the wall after the majority, and its clinical significance are discussed.
