ACASE OF CORROSIVE INJURY OF UPPER GASTROINTESTINAL TRACT EVALUATED BY ENDOSCOPIC ULTRASONOGRAPHY WITH INTRADUCTALI CATHETER PROBE

Abstract

We experienced a case of corrosive injuries of gastrointestinal tract by HCI ingetion.A21 year-old man was admitted to the hospital because of an ingestion of 9.5% HCI.Thegastrointestinal endoscopy showed acute gastric mucosal lesion(AGML)on his firsthospital day. Endoscopic ultrasonogaphy(EUS)with intraductal catheter probe (20MHz)revealed marked thickening of the gastric 3rd layer with heterogenous hypoechoic internal echoes.The lesions encompassed the entire circumference of the gastric wall. These findingsnormalized after 11 days. EUS with intraductal catheter probe was thought to be usefull for the diagnosis of theextent of the corrosive lesions.
