Su1516 The Residual Fraction of Radionuclide Is a Significant Marker for Prediction After Balloon Dilatation in Patients With Primary Achalasia

included elderly patients ( 60 years) with achalasia. The diagnosis was made based on clinic, endoscopic, radiologic and manometric parameters. Characteristics of the patients before, during and after BS placement were documented. Mellow score was used to evaluate dysphagia (0 no dysphagia/1 normal solids/2 dysphagia to soft solids/3 to solids and liquids/4 inability to swallow saliva), we measure the LES pressure and the barium column height at 1 min after swallow. The patients were followed weekly during the first three months after placement then each 15 days until the sixth month and then monthly P 0.05 was considered statically significant. Results: 10 patients with achalasia were included (7men and 3 women). Mean age was 76 7.8 years. Main symptoms were dysphagia and weight loss. Endoprostheses were successfully placed in all cases without complications however all presented chest pain during the first 72hours that was controlled with oral medication. 6 months (3-10) was the mean following period none of the stent was removed. The mean placement time was 35 8.3min. Migration occurred in 2 patients after 7 and 15days but none presented intestinal obstruction or other complication and both then received BTI. The mean degradation time was 80 20 days. Dysphagia score improved in all patients and 2 were able to eat normal diet at the end of the treatment. The mean basal LES pressure decreased 11.7 2.1mmHg (p 0.01) after treatment. Barium column height decreased 4.2 2.5cms after treatment (p 0.022). Final mean weight gain after treatment was 25 8% (p 0.017). Table 1 Conclusion: BS represents a safe and effective treatment in elderly patients with achalasia
