ACUTE GASTRIC MUCOSAL LESIONS DEVELOPING AFTER ENDOSCOPIC EXAMINATION

-COMPARISON BETWEEN EARLY AND LATE ONSET CASES-

Abstract

Approximately 49, 200 endoscopic examinations have been perfomed for last 5 years. After these endoscopic examinations, 15 cases (0.03%) with acute gastric mucosal lesion (AGML) or acute gastroduodenal mucosal lesion (AGDML) were detected without any other causes. Age of the cases ranged from 30 to 61 with an average of 49.7. A male to female ratio was 11 to 4. The lesions were almost seen in the antrum. Most lesions occurred after the first endoscopic examination. The endoscopic examination prior to the onset often revealed erosive gastitis. The period from the day of the initial endoscopic examination to the onset of symptom ranged from 1 to 8 days with an average of 5.0 days. Two of 15 cases developed within 24 hours and had mild symptoms. In these cases, the lesions were found in the body to the f ornix of the stomach. On the other hand, other 11 cases occurred after 3 to 8 days with severe epigastric pain and vomiting and endoscopically lesions developed mainly in the antrum and the duodenal bulb. From the results, it is suggested that there could be two different clinical features among AG (D) ML after endoscopic examination.
