AIM: To investigate the feasibility of a single-use endoscopy as an alternative procedure to nasogastric lavage in patients with acute gastrointestinal (GI) bleeding. METHODS: Patients who presented with hematemesis, melena or hematochezia were enrolled in this study. EG scan™ and conventional esophagogastroduodenoscopy (EGD) were subsequently performed. Active bleeding was defined as blood in the stomach, and inactive bleeding was defined as coffee ground clots and clear fluid in the stomach. The findings were recorded and compared. RESULTS: Between January and March, 2011, 13 patients that presented with hematemesis (n = 4), melena (n = 6), or bleeding from a previous nasogastric feeding tube (n = 3), were enrolled in this study. In 12 patients with upper GI bleeding, the EG scan device revealed that 7 patients had active bleeding and 5 patients had inactive bleeding, whereas conventional EGD revealed that 8 patients had active bleeding and 4 patients had inactive bleeding. The sensitivity and specificity of the EG scan device was 87.5% and 100% for active bleeding, with conventional EGD serving as a reference. No complication were reported during the EG scan procedures. CONCLUSION: The EG scan is a feasible device for screening acute upper GI bleeding. It may replace nasogastric lavage for the evaluation of acute upper GI bleeding.
