Perforations of acute and chronic duodenal ulcers were compared in 70 patients by analysis of the age and racial incidence, the acid output and the histology of the ulcer edge at the time of perforation. There was no significant difference between the ulcer types when these variables were considered. It is suggested that the only difference is the perseverance of symptoms and likelihood of relapse in the chronic group, and that in pathological terms the only true acute ulcer is the rare stress ulcer.
通过对70例患者的年龄、种族发病率、胃酸分泌量以及穿孔时溃疡边缘的组织学分析，对急性和慢性十二指肠溃疡穿孔进行了比较。当考虑这些变量时，溃疡类型之间没有显著差异。研究表明，唯一的区别在于慢性组症状的持续时间和复发的可能性，从病理学角度来看，唯一真正的急性溃疡是罕见的应激性溃疡。
