INTRODUCTION: Balloon dilation therapy is considered treatment of choice for achalasia. Assessment of success after balloon dilation is traditionally according to patient self report of symptom improvement but recently objective assessment showed to be more reliable. We are going to propose a visual scale used endoscopic findings to estimate prognosis of treatment in achalasia patients. AIMES:In order to propose a simple, cheap and reliable method for evaluation of success and outcome in achalasia patients, endoscopic visual scale (EVS) was composed. MATERIALS AND METHODS:It was a quasi-experimental (observational- experimental) study in which data was collected prospectively by convenience sampling (because of rarity of the disease). Patients' characteristics and symptom scores were collected through a questionnaire filled out by a physician. Endoscopic data -consist of mucosal tearing and lower esophageal sphincter opening-were gathered immediately after endoscopy by investigator. All patients who underwent pneumatic dilation for achalasia in Poursina Hakim GI clinic -as the sole center for balloon dilation therapy in Isfahan province- from September 2002 to September 2004, were potential participants in this study (n=39). The diagnosis of achalasia was based on the results of radiographic and endoscopic studies. RESULTS: The degree of patient symptoms improvement one month post therapy was correlated with endoscopic visual score. Roc curve was used to determine the cut-of point of EVS which reveals widest area (0.84, Std. error: 0.08, p-value: 0.009) at the point 3. Patients were then categorized into two groups: (A) those with EVS 3 (n=28) and (B) those with EVS<4(n=9). Statistical analysis shows significant reduction in scores of group A (p=0.001). On the other hand remission of group B is not considerable. (p>> 0.05). CONCLUSION: Usiong endoscopic visual scale, practitioners could predict sufficiency of pneumatic dilation easily and need of repeated endoscoy would be subsided..
