目的 :探讨贲门失弛缓症患者食管动力学及气囊扩张的疗效。方法 :在内镜及X线监视下 ,用OTW气囊对 1 6例患者进行扩张 ,压力为 80～ 1 5 5kPa,维持 30s～1min ,反复 3～ 5次。对 7例患者在扩张前后使用瑞典产C—TD、PCPolyral压力测定仪作了下食管括约肌 (LES)压力、上食管括约肌 (UES)压力检测。结果 :1 6例患者临床症状显著改善 ,可进半流食和普食。 7例患者治疗前LES压力 (7 4± 1 4)kPa,扩张治疗LES压力 (3 4± 0 5 2 )kPa ,扩张治疗后LES压力较治疗前明显下降 (P <0 0 1 )。结论 :贲门失弛缓症存在明显食管动力障碍 ,气囊扩张疗效显著 ,采用渐进式气囊扩张方法 ,可避免食管穿孔的发生。
Objective: To investigate the effects of esophageal motility and balloon dilation in patients with achalasia. Methods: Endoscopic and X-ray monitoring, the use of OTW balloon expansion of 16 patients, the pressure of 80 ~ 155kPa, maintaining 30s ~ 1min, repeated 3 ~ 5 times. Seven patients underwent esophageal sphincter (LES) pressure and upper esophageal sphincter (UES) pressure measurements before and after dilatation using Swedish C-TD and PCPolyral pressure gauge. Results: The clinical symptoms of 16 patients were significantly improved, can be fed into the semi-liquid food and general diet. LES pressure (7 4 ± 1 4) kPa and dilatation LES pressure (3 4 ± 0 5 2) kPa in 7 patients before treatment were significantly lower than those before treatment (P 0 01). Conclusion: There is obvious esophageal motility disorder in achalasia of cardia, and the effect of balloon dilatation is remarkable. The progressive balloon dilatation method can avoid the occurrence of esophageal perforation.
