This study is comprised of analysis of 107 cases of bezoars, proved by upper G-Ⅰ series, endoscopic examination and surgical exploration, in Kyungpook National University Hospital, from January 1965 to May 1974. Results were as follows: 1) Male was more affected than female, as 64.5%(69 cases). 2) The peak age incidence was 5-19 year-old(43.8% : 47 cases). 3) Winter was peak seasonal incidence, 62.5% : 67 cases, which suggested a relationship between seasonal incidence and the time of harvest and ingest of persimmon and Diospyros lotus. 4) All 107 cases were phytobezoars and there was history of ingestion of persimmon and Diospyros lotus. 5) Bezoars after certain gastric operation(involving total or subtotal reasection) were 5 cases(4.7%) and within 2-3 years after the operation. 6) Gastric ulcerations associated with gastric bezoars were found in 10 cases. 7) Sites of bezoars were ileum (47 cases: 39.1%), stomach(35 cases: 30.0%) and jejunum (20 cases: 20.0%) as frequency. A d only 2 cases were found in the site as colon, but also found in small bowel loops in those cases. The latter suggested difficulty of passage of the bezoar beyond the ileocecal junction. 8) Single bezoar was more than multiple, as 87 cases to 20 cases. 9) Chief complaints or symptoms were abdominal pain (in epigastrium, whole addomen or periumbilical area), vomiting, palpable mass and melena, as frequency.
