Abstract
Background. Portal vein (PV) thrombosis (PVT) is a common complication of liver cirrhosis and can refer to thrombosis within the PV that can extend to its left or right branches and in some cases to the superior mesenteric vein or the splenic vein (Chawla and Bodh, 2015). For severe PVT patients, there are possibilities of increasing PV resistance and reduction of the blood flow though PV towards liver, which exacerbate liver function damage meanwhile elevating the gastrointestinal variceal bleeding risk. Endoscopic Variceal band ligation (EVL) is often used to prevent esophageal variceal bleeding; postoperative complications such as severe gastrointestinal bleeding and bleeding-related death, fever, retrosternal pain, and esophageal stenosis may appear. There was absence of the research which evaluated the impact of PVT in liver cirrhosis on the complication of endoscopic Variceal band ligation for now. We herein aimed to compare cirrhosis patients with and without PVT of recent complications after EVL. Method. We established the retrospective investigation on 144 consecutive cirrhosis patients (excluding patients with hepatocellular carcinoma and who received portal vein-systemic circulation devascularization or shunt surgery, splenectomy, hepatectomy, liver transplantation, transjugular intrahepatic portal vein stent shunt (TIPS), endoscopic varices Variceal ligation, or sclerotherapy before) who have received first endoscopic esophageal varices band ligation in Gastrointestinal Endoscopy Center of the First Affiliated Hospital, College of Medicine, ZheJiang University, between January 2014 and December 2017. Portal vein Doppler ultrasonography, liver computerized tomography (CT), and angiography or liver-enhanced magnetic resonance imaging (MRI) were applied to evaluate the portal vein thrombosis of each patient before EVL. There were 18 patients confirmed with portal vein thrombosis while the other 126 patients without PVT. The primary end point for this research is the upper gastrointestinal hemorrhage and related death occurred from the date of ligation until leaving hospital, and the secondary end point is the appearance of postoperative fever and retrosternal pain. Results. There are no significant differences of gastrointestinal bleeding, bleeding-related death, fever, or retrosternal pain after EVL and the length of hospital stays between cirrhotic patients with or without PVT ( P = 0.34 , 0.51 , 0.58 , 0.61 , 0.88 ). Conclusion. Liver cirrhosis with portal vein thrombosis did not increase incidence of recent complications of the endoscopic Variceal band ligation.
