Title: Effect of Intravenous Bolus Infusion of Erythromycin Prior to Endoscopy in Patients Presenting With Variceal Bleeding: A Prospective, Randomized, Double- Blind ,Placebo Controlled, Trial
Brief Summary: Objectives:

Blood in stomach \& oesophagus in patients with variceal bleeding often obscures the endoscopic view \& makes endoscopic intervention difficult to perform. Erythromycin, a motilin agonist induces gastric emptying. The aim of this study was to assess the effect of Erythromycin on endoscopic visibility and its outcome.
