Endoscopic pneumatic balloon dilation in primary achalasia: predictive factors, complications, and long-term follow-up

SUMMARY Pneumatic dilation (PD) has been widely used in the treatment of idiopathic achalasia with a 70–90% response. The aim of this study was to evaluate the effectiveness of PD and its predictive factors by means of clinical assessment. In addition, we evaluated its safety and the need for subseq...

Zusammenfassung:SUMMARY Pneumatic dilation (PD) has been widely used in the treatment of idiopathic achalasia with a 70–90% response. The aim of this study was to evaluate the effectiveness of PD and its predictive factors by means of clinical assessment. In addition, we evaluated its safety and the need for subsequent surgical intervention. Fifty‐six patients were treated with a Witzel dilator. The response was evaluated at medium (1–5 years) and long term (>5 years). Diverse possible predictive factors to response were analyzed. After the first PD, 85.7% of the 56 patients improved and passed from clinical stage II‐III to clinical stage 0–I (P
