The time of balloon dilatation under endoscope for cardia achaladia

Objective To evaluate the time of balloon dilation under endoscope for cardia achalasia . Methods 20 cardia achalasia patients were treated individually by using 3-min dilatating time (DT)、3-min interval time (IT) and 1-min DT、1-min IT. Then the max width of esophagus (MWE) and LESP were detected before and after treatment for 1 week, 6 months. Results The difficulty in deglutition in both groups disappeared and MWE、LESP were not significantly different . Conclusion The 1 min DT, 1 min IT dilatiny treatment is effective for achalasia. It may shorten the time of treatment and relieve patients' sufferings.
