Urine sugar reagent tablet ingestion causing gastric and duodenal ulceration
Abstract:
The accidental or intentional ingestion of urine sugar reagent (Clinitest) tablets, a potent caustic, has been reported to cause severe esophageal mucosal damage and stricture formation. Gastric mucosal damage was reported once before in a man who intentionally ingested 26 Clinitest tablets. We encountered a case of accidental Clinitest tablet ingestion causing gastric and duodenal ulceration without esophageal damage, a previously undescribed complication of inadvertent Clinitest tablet ingestion. Our case reemphasizes the role of early fiberoptic endoscopy in the evaluation of caustic ingestions.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
