Cascade stomach was first described by Rieder in 1910. At fluoroscopy, barium first fills the dependent,posterior fundus to the highest level of the ridge which produces a radiologically evident demarcation between thefundus and body of the stomach, and then spills or "cascades" into the body and antrum. Many cascade stomachs arethe results of intrinsic gastric lesion. In a total of 1595 upper gastrointestinal series, we had a change to get300 cascade stomach in the Department of Radiolocy, Jeonbug National University Hospital from January 1, 1974 toAngust 31, 1976. The cases were reviewed and the results were analized as follows ; 1. In a total of 1595 cases ofupper gastrointestinal examination cascade stomachs were 300 cases (18.8%) and among them borderline cascadestomachs were 74 cases (24.7%), nonpersistent 45 case (15%), persistent 181 cases (60.3%) 2. In erect lateralview, all the cascade sac was located posteriorly and in erect P-A or A-P view, 238 cases (79.3%) were locatedmedially to the maingastric axis, 36 cases(12%) on the main gastric axis and 26 cases (8.7%) laterally. 3. Amongthe 300 cases of cascade stomachs, 69 cases (23%) were combined with duodenal ulcer, 11 cases (3.7%) gastriculcer, 7 cases(2.3%) gastric malignancy, 114 cases (38%) gastritis, 10 cases (3.3%) ptosis, 2 cases (0.7%) gastricdiverticulum, 4 cases (1.3%) duodenal diverticulum, 3 cases (1%) esophageal varices, 1 case (0.3%) pancreatic headcarcinoma, 1 case gastrectomy, 1 case adhesion after abdominal surgery, 1 case choledochoduodenal fistula. 4.Chief complains of the cascade stomach patients were indigestion, epigastric pain and distress, hunger pain,distention, belching, and weight loss. About 40% of cascade stomach patient had one or more of the above describedsymptoms. 5. Cascade stomach has been considered physiologic or normal deformity but we found that many cascadestomachs were the results of intrinsic or extrinsic gastric lesions. Therefore, when the deformity appearsradiologist should be careful examination of the stomach.
