An 87-year old female with dementia unintentionally ingested the contents of a calcium oxide packet found in a cookie container. Upon initial consultation, she presented with epigastric pain and vomiting. After admission, gastrointestinal endoscopy revealed strong adherence of calcium oxide particles along the gastric mucosa, which was subsequently treated with endoscopic gastric lavage. On the second day, follow-up endoscopy revealed a gastric ulcer (stage Al) in the lesser curvature of the stomach. The patient was diagnosed as having a corrosive gastric ulcer based on the ingestion of calcium oxide and she was treated with a proton pump inhibitor. The patient was then discharged from the hospital. However, one month later, the patient suddenly complained of reoccurring abdominal pain. Abdominal computed tomography showed free air in the peri-hepatic area. Emergency endoscopy of the upper gastrointestinal tract revealed a perforation in the lesser gastric curvature. An emergency laparotomy (omental implantation) was performed. The patient was then discharged on the 68th day without any further events. This case report describes an accidental ingestion of desiccant material with subsequent development of a gastric ulcer and perforation, the first report of its kind in adults.
