Forty patients with bleeding oesophageal varices were studied during treatment by endoscopic sclerotherapy to discover what factors determine successful outcome. Large varices required more injections than small varices for obliteration, and rebleeding during treatment occurred only in patients with large varices. Radiological studies with sclerosant contrast mixture showed that in two groups of varices of comparable size, intravenous sclerosant was significantly more effective, leading to thrombosis in 8/10 as opposed to only 3/10 after paravasal injection (p less than 0.05). Intravenous contrast was rapidly cleared upwards, whereas paravasal contrast formed a rounded opacity alongside the vein that persisted for approximately 90 minutes, responsible for the complications of oesophageal ulceration and stenosis.
对40例食管静脉曲张出血患者进行内镜硬化治疗,以探究决定治疗成功的因素。大静脉曲张比小静脉曲张闭塞所需的注射次数更多,且治疗期间再出血仅发生在大静脉曲张患者中。用硬化剂造影剂进行的放射学研究表明,在两组大小相当的静脉曲张中,静脉内注射硬化剂明显更有效,导致10例中有8例发生血栓形成,而旁静脉注射后仅10例中有3例发生血栓形成(p<0.05)。静脉内造影剂迅速向上清除,而旁静脉造影剂在静脉旁形成一个圆形不透明区,持续约90分钟,这是食管溃疡和狭窄并发症的原因。
