In the case of 47-year-old patient who had been suffering for several months from a duodenal ulcer disease, a so called double pylorus was traced by applying fiberoptic gastroscopy. At the same time proof was found for the ulcera duodeni. Owing to the fiberoptic result of two regularly pyloric canals it was already doubted, that this was only a question of a secondary pyloro duodenal fistula caused by peptic ulcer. A particular and differentiating pathological anatomical examination of the surgical specimen showed as a result, that the patient was suffering from a congenital duplication of the pyloric canal by a pyloric ligament. The duodenal ulcers, proofed by x-ray examination and gastroscopy, were recognised as a secondary disease of a locus minoris resistentiae.
在一名患有十二指肠溃疡疾病数月的47岁患者中，通过纤维胃镜检查发现了所谓的双幽门。同时也证实了十二指肠溃疡的存在。由于纤维胃镜检查显示有两条规则的幽门管，当时就有人怀疑这不仅仅是消化性溃疡导致的继发性幽门十二指肠瘘的问题。对手术标本进行的特殊且具有鉴别意义的病理解剖检查结果表明，该患者患有先天性幽门管被幽门韧带重复的情况。经X线检查和胃镜检查证实的十二指肠溃疡，被认定为一个抵抗力较弱部位的继发性疾病。
