Summary
Rigiflex balloon dilatation is a safe and effective treatment for achalasia cardia. This procedure achieved a 93.3% success rate with minimal complications in patients with esophageal motility disorders.
Area of Science:
- Gastroenterology
- Endoscopy
- Medical Devices
Background:
- Achalasia cardia is a rare esophageal motility disorder characterized by impaired peristalsis and LES relaxation.
- Traditional treatments for achalasia include pneumatic dilatation, Heller myotomy, and medications, each with varying efficacy and risks.
Purpose of the Study:
- To evaluate the safety and efficacy of polyethylene balloon achalasia dilators (Rigiflex) for treating achalasia cardia.
- To assess the success rate and complication profile of Rigiflex dilators in a cohort of achalasia patients.
Main Methods:
- A total of 20 dilatation sessions were performed in 15 patients diagnosed with achalasia cardia.
- Initial dilatation involved a 30 mm Rigiflex balloon inflated to 9 psi for one minute.
- Repeat dilatations, if necessary, utilized a 35 mm balloon, with decisions based on symptom assessment.
Main Results:
- The overall success rate of Rigiflex balloon dilatation was 93.3%.
- The 30 mm balloon provided satisfactory results in 73.3% of patients, while the 35 mm balloon achieved a 75% success rate in subsequent procedures.
- Only one patient required surgery, and no short-term complications were observed. Late complications included gastroesophageal reflux in two patients over a mean follow-up of 16.2 months.
Conclusions:
- Rigiflex balloon dilatation is a safe, effective, and straightforward procedure for managing achalasia cardia.
- The use of polyethylene dilators offers a favorable risk-benefit profile for achalasia treatment.
