[Surgery of esophageal achalasia--possible complications]

The authors demonstrate on a group of patients operated by a miniinvasive method possible complications of treatment of achalasia of the oesophagus. On a group of 61 patients they analyze all complications and try to detect their causes. They divide complications into peroperative, early and late postoperative ones. The most frequent peroperative complications are perforation of the oesophagus which are as a rule treated by the laparoscopic route. After surgery the most frequent problem is a relapse of achalasia. The latter is sometimes due to inadequate myotomy. This can be prevented by careful surgical technique along with peroperative endoscopic control.
