Two cases of ectopic openings of the common bile duct are reported. In one case there was a congenital short duct opening into DI, the presence of a spontaneous duodenobiliary reflux due to absence of the papilla being demonstrated by clinical and radiological examinations. The other patient had a long duct opening into D3 and no duodenobiliary reflux, but with an intact sphincter of Oddi explored in detail by means of combined choledochoduodenal manometry. These two cases demonstrate that the duodenal wall has only a moderate effect in preventing duodenobiliary reflux. The essential element is the sphincter of Oddi: if present, there is no reflux, if absent, reflux occurs.
报告了两例胆总管异位开口的病例。一例为先天性短导管开口于十二指肠第一段（D1），临床和放射学检查证实由于乳头缺如存在自发性十二指肠胆管反流。另一例患者有一长导管开口于十二指肠第三段（D3）且无十二指肠胆管反流，但通过联合胆总管十二指肠测压法详细探查了Oddi括约肌功能完整。这两例病例表明十二指肠壁在预防十二指肠胆管反流方面仅有中等作用。关键因素是Oddi括约肌：若存在，则无反流；若缺如，则发生反流。
