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.
