Medical myotomy for achalasia cardia. Long term results.

: Pneumatic dilatation was effective in relieving dysphagia in 16/17 subjects with achalasia cardia. It was also effective and safe in those with sigmoid oesophagus, although dilatation persisted in them. Recurrences were noted in one quarter of cases which were managed satisfactorily with subsequent dilatations. There were no complications. Pneumatic dilatation appears very useful in the management of achalasia cardia.
