Acute oesophageal necrosis (AON) is a rare condition characterised by the endoscopic finding of diffuse, circumferential, black mucosal pigmentation of the oesophagus, which typically stops at the gastro-oesophageal junction. This observational study aimed to assess the occurrence, clinical characteristics and outcomes of AON in a consecutive endoscopic cohort in a single tertiary university centre. A retrospective analysis of endoscopic data of upper gastrointestinal endoscopy (UGE) was carried out from 2008 to 2018.

Background: Massive gastrointestinal bleeding in children is uncommon. Dieulafoy lesion is an uncommon disease which may lead to massive and repeated upper gastrointestinal hemorrhage. We report two cases of gastric Dieulafoy lesion successfully treated with either band ligation or endoscopic hemoclipping. CASE PRESENTATION: First case report: A previously healthy 18-month-old female infant with E. coli sepsis, pneumonia and respiratory failure with bilateral pneumothorax requiring chest drainage.
