微探头超声在食管静脉曲张腔内外联合断流术中的应用

目的运用微探头超声观察门脉高压症食管静脉曲张患者食管下段壁内外静脉结构治疗前后的变化以及对腔内外联合断流术的疗效、预后进行评价。方法对23例门脉高压食管静脉曲张患者，在接受腔内外联合断流术前后应用微探头超声对食管下段静脉结构情况进行对比观察。随访追踪食管静脉曲张的复发率、再出血率。结果治疗后食管黏膜下曲张静脉消失，食管周围静脉丛曲张程度也明显减轻或消失。短期追踪随访静脉曲张的再发率和出血率分别为5．0％和0。结论腔内外联合断流能有效闭塞食管下段壁内外的静脉，阻断门奇分流，防治食管静脉曲张出血与复发，而且操作简便，值得推广应用。微探头超声检查食管下段静脉的变化在食管静脉曲张治疗的评价中具有重要意义。

Clinical value of miniature ultrasonic probe on a combination of endoscopic varices ligation and Hassab′s procedure in the treatment of esophageal varices

Objective To assess the efficacy and prognosis of a combination of endoscopic varices ligation(EVL) and Hassab procedure in patients with portal hypertension by miniature ultrasonic probe. Methods Twenty-three patients with esophageal varices received a combination of EVL and Hassab procedure for variceal eradication. The esophagus vascular structures were examined with endoscopy and miniature ultrasonic probe. Change of vascular structure was evaluated,recurrence and rebleeding of esophageal varices were investigated.Results After treatment,the esophageal varices were obliterated and collateral veins were diminished in size or obliterated. During a short-term follow-up,the recurrence and rebleeding rate of esophageal varices were 5.0 % and 0,respectively.Conclusions The combination of EVL and Hassab procedure can effectively shut off the portoazygous shunt,prevent esophageal varices bleeding. It is a simple and less cost procedure. The miniature ultrasonic probe plays a more important role in evaluating the treatments of esophageal varices.
