A roentgenological study of duodenal diverticula in Korean


Duodenal divertculum is a pouch like protrusion of the mucous membrane through a weak area or defect of the muscle layer of the duodenal wall. 206 cases of the duodenal diverticula out of the consecutive 4030 cases on upper G-I series during the period from Feb. 1977 to Aug. 1978 in the Dep. of Radiology, College of Medicine, Hanyang University were studied. The results were as follows; 1. Overall incidence of duodenal diverticula was 5.1 per-cent (5.0 per-cent in male, and 5.3 per-cent in female). 2. The incidence of duodenal diverticula were 1.4per-cent in the age group below 19, 1.4 per-cent in the second decade. 0.8 per-cent in the third decade, 2.4 per-cent in the fourth decade, 5.3 % in the fifth decade. 10.2% cent in the sixth decade, 9.2% in the seventh decade, and 17.0% in the age group over 70. The incidence of duodenal diverticula is higher in the older individuals. 3. Male was more frequently affected in the age group below 40, but more in females in the age group over 40. 4. 76.3% of duodenal diverticula were found in the concave side of the second portion of the duodenum. 5. Multiplicity of duodenal diverticula was 5.8% of cases. Triple duodenal diverticula were found in 1 case. 6. The size of duodenal diverticula was variable form 3 to 70mm in diameter. More than half of duodenal diverticula wesmaller than 9mm in diameter. Large diverticula of more than 30mm in diameter were 13.6 % of cases. The sized of the duodenal diverticula were relatively large in older age group.
