Thirty-three patients treated at the Karolinska Hospital for achalasia of the esophagus during the period 1968--78 have been reexamined. Twenty-eight of these patients underwent pneumatic dilatation. Excellent and good results were obtained in 79% of cases; in 21% the result was considered poor. In 2 cases the esophagus was perforated during dilatation--a perforation rate of 5% of the total number of dilatations. In 6 cases the lower sphincteric pressure was calculated before and after dilatation. It was found to be higher than normal, preoperatively, but reduced to a near-normal value postoperatively.
1968年至1978年期间在卡罗林斯卡医院接受治疗的33例食管贲门失弛缓症患者接受了复查。其中28例患者接受了气囊扩张术。79%的病例取得了优异和良好的效果；21%的病例效果被认为较差。2例患者在扩张过程中食管穿孔——穿孔率占扩张总数的5%。6例患者在扩张前后计算了下括约肌压力。术前发现其高于正常水平，但术后降至接近正常的值。
