Pneumatic balloon dilatation of the lower esophageal sphincter is commonly utilized as primary therapy for achalasia. Perforation related to pneumatic dilatation is uncommon (2-6%) but may result in severe morbidity. Factors associated with risk of perforation are not well defined. We noted perforation in three patients undergoing forceful balloon dilatation. All these patients had clinical evidence of significant malnutrition (recent marked weight loss and severe hypoalbuminemia). Malnutrition may be a causal factor for perforation in patients with achalasia undergoing dilatation.
食管下括约肌气囊扩张术通常被用作贲门失弛缓症的主要治疗方法。与气囊扩张相关的穿孔并不常见（2%-6%），但可能导致严重的发病情况。与穿孔风险相关的因素尚未明确界定。我们注意到3例接受强力气囊扩张的患者发生了穿孔。所有这些患者都有明显营养不良的临床证据（近期体重显著减轻和严重低白蛋白血症）。营养不良可能是贲门失弛缓症患者扩张时发生穿孔的一个致病因素。
