Gastro‐oesophageal varices are the major clinical manifestations of cirrhosis and portal hypertension. Although less frequent than oesophageal varices (EV), bleeding from gastric varices (GV) is generally more severe and associated with higher mortality and a greater risk to rebleed. According to Sarin's classification, GVs are categorized into four types based on their location within the stomach and relationship with EV. Currently, treatment options for the management of GV include beta‐blockers, endoscopic band ligation, endoscopic cyanoacrylate injection, EUS‐guided coil/cyanoacrylate injection, transjugular intrahepatic portosystemic shunts and balloon‐occluded retrograde transvenous obliteration. The best treatment strategy of GV remains controversial because of the heterogeneity of GV, lack of high‐quality data and suboptimal trial design of the studies available. The proper treatment algorithm may require adequate endoscopic and imaging evaluation by a multidisciplinary team with multiple treatment options available. This review describes the hemodynamic features of GV, pharmacological, endoscopic and interventional radiological treatment options for GV.

Background Some studies have shown that transjugular intrahepatic portosystemic shunt (TIPS) placement within 72 hours of admission improves survival in patients at high risk who present with acute variceal bleeding. However, the role of small-diameter covered TIPS in the secondary prophylaxis of variceal bleeding is still debatable. Purpose To compare the efficacy of 8-mm TIPS and endoscopic variceal ligation (EVL) plus propranolol in the prevention of variceal rebleeding among participants with advanced cirrhosis. Materials and Methods Between June 2015 and December 2018, participants admitted to the hospital for variceal bleeding were considered for enrollment in this randomized controlled trial (ClinicalTrials.gov). Participants with Child-Pugh class B or C cirrhosis were randomly assigned to receive an 8-mm covered TIPS or EVL and propranolol. The primary end point was recurrent variceal bleeding assessed using Kaplan-Meier curve analysis. Secondary end points included survival and overt hepatic encephalopathy (HE) assessed using Kaplan-Meier curve analysis. Results A total of 100 participants were enrolled, with 50 randomly assigned to the EVL plus propranolol group (median age, 54 years; IQR, 45-60 years; 29 male, 21 female) and 50 randomly assigned to the TIPS group (median age, 49 years; IQR, 43-56 years; 32 male, 18 female). The median follow-up period was 43.4 months. In the TIPS group, variceal rebleeding risk was reduced compared with variceal rebleeding risk in the EVL plus propranolol group (hazard ratio [HR], 0.31; 95% CI: 0.14, 0.69; P = .008), but the incidence of overt HE was higher in the TIPS group (30.0% vs 16.0%, P = .03). No differences in survival were observed between the two groups (1-year survival: TIPS, 98.0%; EVL plus propranolol, 92.0%; 3-year survival: TIPS, 94.0%; EVL plus propranolol, 85.7%; HR, 0.52; 95% CI: 0.19, 1.42; P = .22). Conclusion When compared with EVL plus propranolol, 8-mm TIPS led to reduced variceal rebleeding but did not impact overall survival in participants with Child-Pugh class B or C cirrhosis.

Total glucosides of paeony (TGP), an active mixture extracted from paeony root, has anti-inflammatory and immunoregulatory effects and is widely used for the treatment of autoimmune diseases such as rheumatoid arthritis. However, the role of TGP in autoimmune hepatitis (AIH) is still unknown. In this study, we aimed to investigate the effect of TGP in autoimmune liver disease (AILD) patients and in concanavalin A (Con A)-induced experimental autoimmune hepatitis (EAH). Changes in biochemical parameters of AILD patients showed that treatment with TGP exerts significant protective effects on liver function, as reflected by decreased levels of serum alanine transaminase, aspartate transaminase, γ-glutamyl transpeptidase and total bilirubin. In EAH mice, we found that pretreatment with TGP reduced the levels of serum liver enzyme levels, histopathological damage and hepatocyte apoptosis. Importantly, flow cytometry analysis showed that pretreatment with TGP reduced the infiltration of mature dendritic cells in the liver. In vitro, TGP pretreatment ameliorated the Con A-induced mitochondrial membrane potential decline, reactive oxygen species increase, and apoptosis increase in hepatocytes. In addition, the levels of Bax, Cleaved Caspase-3 and cytoplasmic Cytochrome C decreased during this process, whereas those of Bcl-2 and mitochondrial Cytochrome C increased. Therefore, TGP might decrease hepatocyte apoptosis through the mitochondrial apoptotic pathway. Moreover, the maturation of bone marrow dendritic cells was also inhibited by TGP treatment. In conclusion, TGP treatment ameliorates AIH by regulating hepatocyte apoptosis and DC maturation. TGP is a potential compound for AIH treatment.
