目的 探讨黄斑马导丝引导下置入三腔喂养管对上消化道狭窄患者的应用效果。方法 选取43例上消化道狭窄患者,随机分为A组( n =21,经胃镜活检孔插入鼠齿钳置入三腔喂养管)和B组( n =22,经黄斑马导丝引导下置入三腔喂养管),比较两组置管成功率、置管时间及相关并发症。结果 A组置管时间为( 27.43± 6.68)min,高于B组置管时间[(8.95±2.54) min],差异有统计学意义( t =11.879, P <0.05)。A组一次置管成功率为57.1%(12/21),低于B组的置管成功率[95.5%(21/22)],差异有统计学意义(χ^2= 6.820 , P < 0.05 )。A组并发症发生率为42.9%(9/21),明显高于B组并发症发生率[13.6%(3/22)],差异有统计学意义(χ^2= 4.560 , P <0.05)。结论 经胃镜黄斑马导丝引导三腔喂养管应用于上消化道狭窄患者置管时间短、成功率高、并发症少,值得临床推广使用。
食管胃底静脉曲张是肝硬化门脉高压患者常见的并发症之一,严重时可导致上消化道大出血,甚至引起患者死亡。增强CT扫描可以评估肝硬化的严重程度及其相关并发症,在肝硬化食管胃底静脉曲张诊断方面有很重要的价值。本文就增强CT在食管胃底静脉曲张中应用的研究进展进行综述。Esophagogastric varices are one of the common complications in cirrhotic patients with portal hypertension, which can lead to massive upper gastrointestinal bleeding and even death. Enhanced CT scan can evaluate the severity of liver cirrhosis and its related complications, which is of great value in the diagnosis of esophagogastric varices in liver cirrhosis. This article reviews the research progress in the application of enhanced CT in esophageal and gastric varices.
