The term "ectopic varices" is used to describe dilated portosystemic collateral veins in unusual locations other than the gastroesophageal region. We recently experienced a rare case of ectopic varices that developed in the gastroduodenal anastomosis after subtotal gastrectomy. A 70-year-old male with liver cirrhosis due to hepatitis C virus infection was admitted for hematemesis and tarry stool. He had received a subtotal gastrectomy with the Billroth-I method for gastric ulcer at 46 years of age. Although emergency endoscopy revealed esophageal and gastric fundal varices, there were no obvious bleeding points. After removal of the coagula, ectopic varices and a fibrin plug were observed on the gastroduodenal anastomosis. During the observation, blood began to spurt from the fibrin plug. N-butyl-2-cyanoacrylate with lipiodol injection succeeded in hemostasis. Splenic angiography showed gastric varices feeding from a short gastric vein and the posterior gastric vein. The blood flow around the bleeding point, as indicated by lipiodol deposition, had decreased, and no feeding vein was observed. Endoscopic and angiographic findings are shown and the treatment for such lesions is discussed.
术语“异位静脉曲张”用于描述在胃食管区域以外的异常位置出现的扩张的门体侧支静脉。我们最近遇到了一例罕见的异位静脉曲张病例,其发生在胃大部切除术后的胃十二指肠吻合处。一名因丙型肝炎病毒感染导致肝硬化的70岁男性因呕血和柏油样便入院。他在46岁时因胃溃疡接受了毕罗一式胃大部切除术。尽管急诊内镜检查发现食管和胃底静脉曲张,但没有明显的出血点。清除血凝块后,在胃十二指肠吻合处观察到异位静脉曲张和一个纤维蛋白栓。观察期间,血液开始从纤维蛋白栓处喷射而出。注射碘化油的氰基丙烯酸正丁酯成功止血。脾血管造影显示胃静脉曲张由胃短静脉和胃后静脉供血。如碘化油沉积所示,出血点周围的血流减少,未观察到供血静脉。展示了内镜和血管造影的结果,并讨论了此类病变的治疗方法。
