PROGNOSTIC PARAMETERS AFTER SURGICAL-TREA TMENT OF ACHALASIA

For operative treatment of achalasia transabdominal myotomy combined w ith a semifundoplication was performed in 37 patients. 35 patients cou ld be followed up during an average period of 41 months. 19 patients ( 54 %) were completely and 12 (34 %) almost symptom-free. In one case a peptic esophageal stenosis developed. The results of operation were e specially in the group of young patients under 40 years favourable and there was no influence on results of preoperative duration of symptom s or number of dilatations before surgery. Transabdominal myotomy with semifundoplication has shown as a procedure with low complication rat es and good long-time results for the symptomatically therapy of achal asia.
