Endoscopic Mechanical Dilation for Cardia Achalasia:Roport of 62 Cases / 中国微创外科杂志

ABSTRACT

Objective To evaluate the effect of mechanical dilation on cardia achalasia under an endoscope.Methods A total of 62 patients with cardia achalasia were treated with mechanical dilation by using a self-designed dilator under a gastroscope.Of the cases,one had experienced a failure of heller surgery,and four had received ballon dilation before the gastroscopy.Results Among the cases,2 were convered to open thoracic surgery becaues of rupture of the esophagus,1 patient could not tolerate the operation,1 received a second dilation because of unsatisfied outcome of the first attempt.In the other 58 patients,the surgery was completed in the first attempt.The mean dilation time was 3.5 minutes(ranged from 2 to 5 minutes).Slight mucosal hemorrhage was observed during the operation,while no continuous bleeding occurred.Cold liquid diet was given to the patients 2 hours after the dilation,and then semiliquid diet was prescribed in 6 hours,after that the patients began to take normal diet gradually.The patients were followed up for 2 to 11 years with a mean of 7.5.All of them were cured without recurrence.Conclusions Endoscopic mechanical dilation is microinvasive,safe,and effective for cardia achalasia.It is worth being widely used because of a low cost and reliable long-term outcomes.
