目的：探讨成人Ｏｄｄｉ括约肌环的长度，以便提高Ｏｄｄｉ括约肌切开或成形术的疗效。方法：用Ｈａｎｄ法测定２６具成人尸体标本括约肌长度；用胆道造影法测定５４例手术病人括约肌长度。结果：２６具尸体胆管括约肌为１２．１±３．５ｍｍ，胰管括约肌为９．５±３．３ｍｍ，壶腹括约肌为４．９±１．６ｍｍ；５４例患者胆管下段括约肌为２５．３±４．２ｍｍ，２０例胰管括约肌为６．５±２．４ｍｍ。结论：成人Ｏｄｄｉ括约肌环长度个体间差异较大，不宜按照固定长度作为括约肌切开的标准。
Objective: To investigate the length of adult Oddi sphincter ring in order to improve the efficacy of sphincterotomy Oddi or angioplasty. Methods: The sphincter length of 26 adult cadaver specimens was determined by Hand method. The sphincter length of 54 surgically treated patients was determined by cholangiography. RESULTS: Twenty-six cadaveric sphincters were 12.1 ± 3.5 mm, pancreatic duct sphincter was 9.5 ± 3.3 mm, ampullary sphincter was 4.9 ± 1.6 mm, while in 54 cases, biliary sphincter was 25.3 ± 4.2mm, 20 cases of pancreatic sphincter 6.5 ± 2.4mm. Conclusion: Oddi sphincter adult adult ring length differences between individuals larger, not in accordance with the fixed length as the sphincterotomy standards.
