Of all cases of cirrhosis-related ascites, only 0.5%-1% is chylous[112]. The underlying mechanism is believed to be excessive hepatic and gastrointestinal lymph flow and pressure secondary to PH, which may lead to spontaneous rupture of ser...

PHG is characterized by vascular ectasia, which appears as a mosaic-like pattern of gastric mucosa on endoscopy[58,59]. PHG的特点是血管扩张，在内镜[58,59]上呈胃黏膜马赛克样模式。 The reported prevalence of PHG ranges from 20%-98% in patien...

The term ectopic varices are used to describe portosystemic collaterals located at sites other than the gastroesophageal region. 异位静脉曲张一词被用来描述位于胃食管区域以外部位的门体侧支。 Stomal varices are the most common, followed by s...

已知孤立性胃静脉曲张存在于门静脉高压患者100多年【1】，然而只在过去20年才开始研究。很多问题依然未知。 1. 门静脉高压患者胃静脉曲张精确发生率 2. 几乎没有关于胃静脉曲张的自然病史信息。 3. 胃静脉曲张出血来自有或没有食道静脉曲张的确切情况不清 胃...

Other explanations proposed for the suboptimal efficacy of TIPS in controlling GVH are the proximity, throughput, and recruitment theories[35-37]. 对于TIPS在控制GVH方面的次优疗效的其他解释是贴近度、通过量和招募理论[35-37]。 The proximity t...

Variceal bleeding is one of the major complications of portal hypertension. 静脉曲张出血是门脉高压症的主要并发症之一。 Gastric variceal bleeding is less common than esophageal variceal bleeding; however, it is associated with a high morbid...

经颈静脉肝内门体分流术（TIPS） 经颈内静脉门体分流术（ TIPS ） 是指经颈静脉插管至肝静脉后，穿刺肝实质至肝内门静脉分支，将可扩张的金属支架植入后建立肝内门静脉与下腔静脉之间的分流道，以使整个肝外门静脉系区域的压力显著降低， 从而达到治疗胃食管...

前言 在最初将适应症定义为顽固性静脉曲张出血患者的拯救性治疗（ rescue therapy ）50多年后，经颈静脉门腔静脉分流 (TIPS)仍然是密集的临床和生物医学研究的焦点。 通过这种干预措施显著降低了门脉压力，再加上其微创性，TIPS在治疗门脉高压并发症方面获得...

第二阶段：在单个或多个机构进行的大型的、前瞻性试验。...
