Improvized pneumatic dilator for achalasia cardia.
The indigenous pneumatic dilator for achalasia cardia reported previously by the authors was being placed alongside the endoscope to perform dilatation under direct vision. It has now been improvised to make the procedure wire-guided and fluoroscopy-assisted as well. The improvization includes insertion of a central Teflon tube for passage of a guidewire and presence of three radio-opaque markers, which define the proximal, central and distal ends of the dilator and help in precise positioning under fluoroscopy. Dilatation for achalasia cardia using the improvized pneumatic dilator with fluoroscopic guidance was performed successfully on 10 patients at our center. All patients had clinical response with greater than 50% improvement in total symptom score. Barium swallow examination after dilatation showed improvement in esophageal transit in all patients. None of the patients developed any complication. Cost of the dilator is approximately 50 times less than that of commercially available dilators. The dilator can be re-used by sterilizing it, which further reduces the cost.
