Combined Endoscopic and Radiographic Evaluation of the Esophagus Immediately After Pneumatic Dilatation for Achalasia

“…However, the literature supporting this stems from case series of esophageal perforations from all aetiologies that have seldom included pneumatic dilation. Miss rates of esophageal perforation with water soluble contrast esophagrams have been reported to range from0-50% [8][9][10][11]. The "gold standard" in these series varied from barium esophagrams, computed tomography (CT) and esophagogastroscopy.Nonetheless, barium esophagram have also been reported to miss rates of up to 10% [12].…”
