Recently, 115 cases of duodenal diverticulum were detected among 6787 cases which received radiological examination on upper gastrointestinal canal.
These cases indicated that detection of duodenal diverticulum might be increased by means of combination with several radiological method, especially so called “double contrast method”.
Probably, it might be caused by summation of weakness and addition of angiosklerotic changes in intestinal tissue that numbers of cases of duodenal diverticulum (maximal peak was in the generation from 50 to 60 years old) and size of diverticulum increased by progression of age.
Many cases were symptomless, but a few cases which had larger diverticulum were suffering from some symptoms (epigastralgia, hypochodralgia, etc.) on epigastrial region.
