Pneumatic dilation of the esophagus is an effective form of therapy to be available to achalasia. To evaluate the criteria predicting the therapeutic effects of pneumatic dilation, the manometric and radiographic appearances of the esophagus with achalasia were analyzed in 32 achalasia patients immediately following pneumatic dilation. A comparison of dysphagia grading and the parameters of the manometric and radiographic studies was made. 1) The pretreatment manometric findings of vigorous achalasia were associated with the significant irriprovement of dysphagia grading score and with high rate of reappearance of peristalsis after pneumatic dilatation. 2) The fall of LES pressure or intraesophageal pressure compare with pretreatment values noted no close relationship to the dysphagia grade after 6 months postdilation. 3) The level of barium fleck (no more than 1 cm) showed a close relationship to the dysphagia grade after pneumatic dilation. 4) The caliber of the esophagogastric channel (more than 8 mm) after dilation showed a close relationship to the dysphagia grade after pneumatic dilation. 5) Reduction of the diameter of the esophageal body was not well correlated with the dysphagia grade after pneumatic dilation. In conclusion, in predicting the clinical response of pneumatic dilation, the esophagogastric diameter or the level of barium fleck in the distal esophagus is the useful criteria to evaluate the effects of pneumatic dilation in achalasia.
