Achalasia cardia dilatation using polyethylene balloon (Rigiflex) dilators.

OBJECTIVE: Results of 20 dilatation sessions in 15 patients with achalasia cardia were assessed to determine the safety and efficacy of polyethylene balloon achalasia dilators (Rigiflex). METHODS: All patients underwent an initial dilatation by inflating a 30 mm balloon to 9 psi for one minute. Need for subsequent dilatations was assessed on symptom assessment; 35 mm balloon was used for repeat procedure. RESULTS: Overall success rate was 93.3%. The 30 mm balloon achieved a satisfactory result in 73.3% and the 35 mm balloon in 75% of the remainder. Only one patient needed surgery. No short-term complications were observed. The only late complication encountered over an average follow-up period of 16.2 months was gastroesophageal reflux in two patients. CONCLUSIONS: Dilatation using Rigiflex dilators is a safe, effective and simple procedure for treating patients with achalasia.
