Non Invasive diagnosis of esophageal�varices in liver cirrhosis
proposed that patients with liver cirrhosis with a lower liver stiffness measurement (LSM) (< 20 kPa) and a higher platelet count (> 150,000/μl) can avoid unnecessary endoscopy for the surveillance of VNT
the LSM (< 25 kPa) and platelet count value (> 110,000/μl)
Baveno VI guidelines
expanded Baveno VI criteria
sensitivity for high-risk varices was 97%, specificity was low 41%
sensitivity and specificity of the Expanded Baveno VI criteria for high-risk varices was 90% and 51%,
sensitivity and specificity were for oesophageal varices and %86 and %59’
Liver stiffness
Artificial intelligence is a general term includes several domains of advanced computer programs that can achieve human like cognitive abilities. Machine-learning is a subdomain of artificial intelligence that learns from the data and the problem without needing to be programmed so. These approaches are increasingly being used in virtually every field of medicine as well as hepatology to tackle
long-standing problems with their inherent abilities to and integrate a bigger dimensions and extent of data into their solution.

Endoscopic therapies
EIS
endoscopic injection sclerotherapy
By using a standard endoscope with a 6-cm oral side and a 23- or 25-gauge injection. Under fluoroscopic guidance, intravariceal injections of 5% ethanolamine oleate (EO) were administered that filled the varices and the supplying vessels. The injections were repeated for multiple varices until the maximum amount of EO (0.4 mL/kg) was injected Usually, sclerotherapy alone was performed weekly until the injectable varices had almost disappeared, then band ligation was undertaken at the injection sites during the final EIS session.
EVL
Esophageal varices ligament
using a standard endoscope attached to a pneumoactivat-ed EVL device, which was introduced along a flexible overtube. The varices were ligated sequentially from the most distallesion EVL was repeated weekly until the varices were completely eradicated; this usually requi-red two or three sessions.

Is it the end ? What's about re-bleeding?
interventional radiology (IVR) therapies
IVR procedures for EVs uncontrollable by endoscopic treatment (ET) alone include two methods: embolization of the collateral vessels and varices, such as via percutaneous transhepatic obliteration (PTO) , and decompression of the portal venous pressure, such as via partial splenic embolization (PSE) and transjugular intrahepatic portosystemic shunt .
partial splenic embolization (PSE)
PSE reduced the hepatic venous pressure gradient and markedly lowered the ChildPugh score.
PSE is recommended for these high-risk patients with splenomegaly when platelet counts of < 50000/μL persist in three consecutive blood samples.
percutaneous transhepatic obliteration (PTO)
(A) Percutaneus transhepatic portography shows from the left gastric vein to the collateral veins including paraesophageal vein, which caused esophageal varices hemorrhage. (B) The feeding veins were embolized with microcoils and a sclerosing agent. (C) Percutaneous transhepatic portography after treatment showing that the varix and its feeder were embolized.

(A, B) Dynamic contrast-enhanced computed tomography (CT) showing a large paraesophageal vein (arrows). (C, D) Follow-up CT after 12 months showing the diminished paraesophageal vein.
transileocolic obliteration (TIO)
(A) Catheterization of the ileocolic vein through the catheter introducer under laparotomy.
(B) Portography showing a large paraesophageal vein before embolization. (C) Portography showing an improved portal vein blood flow in the left lobe of the liver after embolization.
transileocolic obliteration (TIO)
(A) Esophagogastroduodenoscopy showing esophageal varices before the transileocolic obliteration (TIO) procedure. (B) Esophagogastroduodenoscopy six months after TIO showing the shrunken esophageal varices.
Transjugular intrahepatic portosystemic shunt (TIPS)
CONCLUSION
ET is the first therapeutic line for patients with EVs; however, for those with refractory diseases that are resistant to ET, broad knowledge and advanced technology with alternative treatment options, namely IVR therapies, may lead not only to prevention of variceal hemorrhaging but also improvement in the hepatic function and prognosis.
