This is a case report of gastroduodenal ulcer complicated with sapovirus gastroenteritis in a 2-year-old girl. The patient turned pale after suffering from abdominal pain, vomiting and diarrhea as well as bloody diarrhea. She was referred and admitted to this hospital. She received a red blood cell transfusion for anemia. Upper gastrointestinal endoscopy revealed a gastroduodenal ulcer. Active bleeding was not detected. Sapovirus was detected in a stool specimen by polymerase chain reaction (PCR). She was treated conservatively and prescribed famotidine for the ulcer. After six weeks of famotidine treatment, the ulcer improved.
Sapovirus is a virus that causes acute gastroenteritis in adults and children. The symptoms are not usually as severe as rotavirus and norovirus gastroenteritis. Gastroduodenal ulcer in children is not reported in acute gastroenteritis associated with sapovirus, while norovirus and rotavirus sometimes induce gastroduodenal ulcer.
Gastroduodenal ulcer is one cause of abdominal pain in children. Upper gastrointestinal endoscopy should be considered for children with acute gastroenteritis complicated by anemia, hematemesis, and bloody diarrhea. Upper gastrointestinal endoscopy can be useful in such cases for determining appropriate treatment.
