An intraluminal diverticulum of the jejunum in a 19-year-old man is reported. A congenital diaphragm was bypassed by jejunojejunostomy when the patient was 2 days old. A "ballooning" mechanism of this diaphragm can explain the pathogenesis of the diverticulum.
Study of 100 cases of duodenal ulcer has revealed disagreement between radiologic and endoscopic findings. In 20 percent of cases the disagreement was minor (e.g. deformed duodenum - ulcer, deformed duodenum - scar, etc.). In 5 percent of cases they were major (e.g. normal - ulcer). The percentage of discrepancies, which were to the advantage of endoscopy, was lower than in the reports of JENNI and KAWAI, probably because our heterogeneous radiologic material was reviewed beforehand by two radiologists. The specific merit of endoscopy is that it makes it possible to observe superficial and sub-radiologic lesions of the mucosa, localize the ulcer with greater precision and detect deformation of the pylorus. Radiology affords better evidence of certain deformations.
