Previous endoscopic treatment does not affect complication rate and outcome of laparoscopic Heller myotomy and anterior fundoplication for oesophageal achalasia.

Abstract

There was only a trend, although not statistically significant, towards an increased risk of complications and adverse effects in patients previously treated by pneumatic dilation or botulinum toxin. The higher incidence of mucosal tears during the first 30 operations suggests the effect of the learning curve.
