ABSTRACT
Background/Objective: Achalasia is a motility disorder of unknown etiology, characterized by absent esophageal peristalsis and loss of lower esophageal sphincter relaxation. Balloon dilatation is the most effective non-surgical treatment for patients with achalasia. Manometry, scintigraphy and radiology are three techniques that provide an objective measure of success after balloon dilatation. The objective of this study was to determine the best predictor of success after balloon dilatation in patients with achalasia. Patients and Methods: 17 patients with achalasia of cardia who referred to Taleghani Hospital in 2003, were evaluated, both symptomatically and objectively (esophageal manometry, timed barium esophagogram, and scintigraphic emptying index), before and after treating with pneumatic dilatation of esophagus. The degree of patient symptom improvements after treat-ment was recorded and correlated with improvement in some indices derived by the above-mentioned three methods. Results: 12 (70.6%) of 17 patients had score improvements of ≥80%. All the pre-treatment diagnostic indices were significantly (P
