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.
