Erythromycin prior to endoscopy in acute upper gastrointestinal bleeding: A meta-analysis

Abstract Objective. Upper gastrointestinal bleeding (UGIB) is a medical emergency requiring urgent endoscopy and diagnosis. However, adequate visualization is a necessity. Studies have been performed evaluating the efficacy of erythromycin infusion prior to endoscopy to improve visibility and therapeutic potential of esophagogastroduodenoscopy (EGD) with varied results. Therefore, a meta-analysis was performed comparing the efficacy of erythromycin infusion prior to endoscopy in acute UGIB. Materials and methods. Multiple databases were searched. Meta-analysis for the effect of erythromycin prior to endoscopy in UGIB was analyzed by calculating pooled estimates of visualization of gastric mucosa, need for second endoscopy, and units of blood transfused using odds ratio (OR) and weighted mean difference (WMD). Results. Four studies (N = 269) met the inclusion criteria. Erythromycin prior to endoscopy in UGIB demonstrated a statistically significant improvement in visualization of the gastric mucosa (OR 4.8...
