RESUMEN
Objective To evaluate the effect of treating achalasia of cardia by transabdominally HellerDor operation.Methods Thirty-five cases with achalasia of cardia who were treated by transabdominally Heller-Dor procedure were recruited in this study from January 2006 to December 2011.Twenty patients received preand post-operative manometry and 24-hour-pH monitoring.Recorded parameters included pre-and post-operative lower esophageal sphincter pressure (LESP),reflux frequency in 24 hours,the longest duration of reflux,the total time (min) of pH ＜ 4.0 and the percentage (％) of time of pH ＜ 4.0.Statistical analyses were conducted.Results Symptom was significantly improved in 34 patients after surgery,while 1 patient remained dysphasia.Recheck the manometry and 24-hour-pH post-operation at 1 month,the LESP was significantly lower than pre-operation ((10.22 ±8.91)mm Hg vs.(30.81 ±6.63) mm Hg,and the reflux frequency,the longest duration of reflux,the total time (min) of pH ＜ 4.0 and the percentage (％) of time of pH ＜ 4.0 significantly declined at one month after operations (t =2.740,2.335,2.829 and 2.139;P =0.022,0.019,0.036 and 0.040 respectively).Thirty-two patients (91.4％,32/35) were followed up,among whom 24 patients (75.0％,24/32) were cured and 8 patients(25.0％,8/32) improved.Reflux did not detected after surgery in the 4 cases (20.0％,4/20) with preoperative reflux.Conclusion Transabdomianlly Heller-Dor operation could dramatically alleviate the symptoms of patients with achalasia of cardia.Moreover,it could especially prevent pestoperative-reflux,with the advantages of simple operations,little traumas and few complications.
