A retrospective study was performed to asses risk factors in patients with esophageal achalasia undergoing pneumatic dilatation. Of 140 patients who underwent 159 dilatations, 7 sustained esophageal perforation (4.4%). They were matched with a group of 52 non perforated, dilated achalasia patients. History of prior pneumatic dilatation and small esophageal diameter were found to be risk factors by chi square and ANOVA.
进行了一项回顾性研究，以评估接受气囊扩张术的贲门失弛缓症患者的危险因素。在140例接受了159次扩张术的患者中，7例发生食管穿孔（4.4%）。将他们与一组52例未发生穿孔的贲门失弛缓症扩张术患者进行匹配。通过卡方检验和方差分析发现，既往气囊扩张术史和食管直径较小是危险因素。
1）贲门失弛缓症的气囊扩张术穿孔风险为4.4%，死亡率为0.6%。2）既往气囊扩张术和食管直径较小会增加发生食管穿孔的风险。提示存在另一个危险因素，如穿孔部位食管壁可能存在的解剖学薄弱点（以及通过超声检查对其进行评估的可能性）。
