Abstract
Two new cases of patients with so called muscular pyloric band (“double pylorus”) are reported. Both possible genetic mechanisms of this malformation are discussed in detail: primary or congenital, and secondary or acquired by inflammation. After analysis of the hitherto related cases, the opinion is expressed that the so called pyloric band represents a congenital malformation. According to the authors, the striking frequency of simultaneous ocurrence of pyloric band and ulcers does not necessarily favour the theory of inflammatory genesis. The accompanying ulcer seems rather to be a “second disease” in the sense of Rössle (1913), manifesting itself at a locus minoris resistentiae. Es wird von 2 eigenen Beobachtungen eines sog. muskulären Pylorusbandes („double pylorus”) berichtet. Die beiden möglichen Entstehungsmechanismen dieser Mißbildung, nämlich primär, angeboren oder aber sekundär, entzündlich erworben, werden ausführlich diskutiert. Nach genauer Analyse der bisher beschriebenen Fälle wird die Meinung vertreten, daß das sog. Pylorusband eine angeborene Mißbildung darstellt. Das auffallend häufige gemeinsame Vorkommen von Pylorusband und Ulcus spricht nach Meinung der Verfasser nicht notwendigerweise für die entzündliche Genese. Das begleitende Ulcus scheint uns vielmehr eine „Zweitkrankheit” im Sinne von Rössle (1913) zu sein, die sich an einem locus minoris resistentiae manifestiert.Keywords
