BACKGROUND/AIMS: Bleeding from esophageal varices (EV) is a major cause of death in patients with liver cirrhosis. Endoscopic screening is recommended for diagnosing EV, but various noninvasive parameters can also be used to predict EV. The liver stiffness measurement (LSM), a noninvasive technique for estimating liver fibrosis, was recently reported to be strongly correlated with the hepatic venous pressure gradient. This study evaluated the usefulness of LSM for predicting the presence and size of EV in patients with cirrhosis. METHODS: The relationships of LSM with the presence and size of EV were analyzed in 112 patients with liver cirrhosis. Liver cirrhosis was diagnosed histologically or clinically. The presence and size of EV were assessed by endoscopy, and LSM was determined by the Fibroscan(R) technique. RESULTS: LSM was strongly correlated with the presence of EV (P<0.0001): the LSM value was 42.7+/-21.9 kPa (mean+/-standard deviation) in patients with EV (n=82) and 19.1+/-12.6 kPa in patients without EV (n=30). The area under the receiver operating characteristic curve was 0.818 (95% CI, 0.732-0.904) for predicting the presence of EV, and an LSM value of 19.7 kPa was predictive of the presence of EV with a sensitivity of 87%, a specificity of 70%, a PPV of 89%, and a NPV of 66%. However, there was a weak correlation between LSM and the size of EV. CONCLUSIONS: LSM is useful for predicting the presence of EV in patients with cirrhosis but not their size.

OBJECTIVE: To evaluate the feasibility of percutaneous access via the recanalized paraumbilical vein for varix embolization. MATERIALS AND METHODS: Between July 2008 and Jan 2014, percutaneous access via the recanalized paraumbilical vein for varix embolization was attempted in seven patients with variceal bleeding. Paraumbilical vein puncture was performed under ultrasonographic guidance, followed by introduction of a 5-Fr sheath. We retrospectively evaluated the technical feasibility, procedure-related complications, and clinical outcomes of each patient. RESULTS: Recanalized paraumbilical vein catheterization was performed successfully in all patients. Gastroesophageal varix embolization was performed in six patients, and umbilical varix embolization was performed in one patient. Embolic materials used are N-butyl cyanoacrylate (n = 6) and coil with N-butyl cyanoacrylate (n = 1). There were no procedure-related complications. One patient underwent repeated variceal embolization 6 hours after initial procedure via recanalized paraumbilical vein, due to rebleeding from gastric varix. CONCLUSION: Percutaneous access via the paraumbilical vein for varix embolization is a simple alternative in patients with portal hypertension.

OBJECTIVETo assess the effects of different treatment complex on esophageal vascular structures in patients with portal hypertension.

METHODSPatients (142 cases) with esophageal varices received either endoscopic variceal ligation (EVL) alone (54 cases), pericardial devascularization procedure (PDP) alone (23 cases), a combination of EVL and partial splenic embolization (PSE) (34 cases), or a combination of EVL and PDP (31 cases) for variceal eradication. Esophageal vascular structures were examined with miniature ultrasonic probe. The recurrence and rebleeding of esophageal varices were investigated.

RESULTSEsophageal submucous varices were obliterated and collateral veins remained unchanged in patients treated by EVL or EVL combined with PSE; esophageal submucous varices were diminished in size and collateral veins were obliterated by PDP, and both esophageal submucous varices and collateral veins were obliterated by the combination of EVL and PDP.

CONCLUSIONSThe combination of EVL and Hassab's procedure can effectively shut off the portoazygous shunt, prevent esophageal varices from bleeding and recurrence. It's a simply and less cost procedure.

Recent studies suggest that liver cirrhosis is reversible after administering oral nucleos(t)ide analogue therapy to patients with hepatitis B virus (HBV) infection. However, few studies have addressed whether esophageal varices can regress after such therapy. We report a case of complete regression of esophageal varices during entecavir therapy in patients with HBV-related liver cirrhosis, suggesting that complications of liver cirrhosis such as esophageal varices can regress after the long-term suppression of HBV replication.

Some recent studies have found regression of liver cirrhosis after antiviral therapy in patients with hepatitis C virus (HCV)-related liver cirrhosis, but there have been no reports of complete regression of esophageal varices after interferon/peg-interferon and ribavirin combination therapy. We describe two cases of complete regression of esophageal varices and splenomegaly after interferon-alpha and ribavirin combination therapy in patients with HCV-related liver cirrhosis. Esophageal varices and splenomegaly regressed after 3 and 8 years of sustained virologic responses in cases 1 and 2, respectively. To our knowledge, this is the first study demonstrating that complications of liver cirrhosis, such as esophageal varices and splenomegaly, can regress after antiviral therapy in patients with HCV-related liver cirrhosis.
