An audit of pneumatic dilatation and oesophagomyotomy in patients with achalasia cardia.

ABSTRACT

The role of pneumatic dilatation and oesophagomyotomy in the management of achalasia cardia was evaluated. Twenty patients with achalasia cardia managed either by pneumatic dilatation (n = 10) and oesophagomyotomy (n = 10) were studied. Patients undergoing dilatation were followed up for a mean of 20 months (12-30 months) and those undergoing myotomy for 17 months (6-48 months). The patients were evaluated clinically, radiologically and endoscopically. Relief of dysphagia was excellent in 20%, good in 50% and fair in 30% of those who underwent dilatation. In the myotomy group, 60% had an excellent result, 30% had a good result and fair results was observed in 10%. Oesophagitis on endoscopic evaluation, was found in two patients in myotomy group. The diameter of the gastro-oesophageal junction increased from a mean of 2 mm (range 1 to 4 mm) to a mean of 11 mm (range 4 to 15 mm) in dilatation group while in myotomy group it changed from a mean of 2 mm (range 0.5 to 8 mm) to a mean of 9 mm (range 5 to 15 mm). Symptomatic improvement was better after myotomy than after pneumatic dilatation and correlated poorly with radiological features.
