MiR-124 and miR-506 are involved in the decline of protein C in children with extra-hepatic portal vein obstruction.

Sci Rep 2021 Jun 10;11(1):12320. Epub 2021 Jun 10.

Department of General Surgery, Capital Institute of Pediatrics, No. 2 Yabaolu Rd., Beijing, 100020, People's Republic of China.

The deficiency of protein C (PROC) can be partly rescued by Rex shunt through restoring portal blood flow in children with extra-hepatic portal venous obstruction (EHPVO). However, the decline of PROC is still found in some patients with a normal portal blood flow after Rex shunt. The aim of this study was to identify the candidate miRNAs involving in the decline of PROC and their mechanism. Read More

Predictors and risk factors for intestinal necrosis in patients with mesenteric ischemia.

Ann Transl Med 2021 Feb;9(4):337

Department of Gastrointestinal Surgery, Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua University, Beijing, China.

Background: Mesenteric ischemia results in blood flow that is insufficient to meet metabolic demands and subsequent dysfunction of visceral organs, including arterial obstruction and venous thrombosis. Sustained mesenteric ischemia exhausts the ability of capillaries to provide oxygen and initiate an inflammatory reaction, and eventually leads to intestinal mucosal necrosis, a serious and potentially life-threatening condition. Therefore, it is essential that the predictors and risk factors for intestinal necrosis in patients with mesenteric thrombus are explored. Read More

Am J Case Rep 2021 Mar 1;22:e928801. Epub 2021 Mar 1.

Department of Surgery, Iwate Medical University, Morioka, Iwate, Japan.

BACKGROUND Extrahepatic portal vein obstruction (EHPVO) is one of the most important diseases that causes pre-hepatic portal hypertension, and EHPVO sometimes develops cavernous transformation to maintain hepatopetal flow. In this report, we describe the first case of hepatocellular carcinoma (HCC) with EHPVO having underwent pure laparoscopic left hepatectomy with middle hepatic vein (MHV) resection. CASE REPORT A 70-year-old woman with a diagnosis of mixed-type HCC or cholangiocarcinoma located in segment 4b was referred to our hospital, and computed tomography revealed EHPVO with cavernous transformation.

Influence of portal vein occlusion on portal flow and liver elasticity in an animal model.

NMR Biomed 2021 Jun 25;34(6):e4498. Epub 2021 Feb 25.

ICube, CNRS UMR 7357, University of Strasbourg, Strasbourg, France.

Hepatic fibrosis causes an increase in liver stiffness, a parameter measured by elastography and widely used as a diagnosis method. The concomitant presence of portal vein thrombosis (PVT) implies a change in hepatic portal inflow that could also affect liver elasticity. The main objective of this study is to determine the extent to which the presence of portal occlusion can affect the mechanical properties of the liver and potentially lead to misdiagnosis of fibrosis and hepatic cirrhosis by elastography.

Ischemic jejunal stricture in patients with extrahepatic portal vein obstruction.

Indian J Gastroenterol 2021 Feb 6;40(1):82-87. Epub 2021 Jan 6.

Department of Radio-Diagnosis, All India Institute of Medical Sciences, Patna 801 507, India.

Ischemic jejunal stricture due to mesenteric vein thrombosis (MVT) rarely occurs in patients with extrahepatic portal vein obstruction (EHPVO). This is because the thrombus often occludes only a short segment of superior mesenteric vein adjacent to splenoportal confluence, facilitating development of collateral veins that protect bowel from ischemia. However, ischemic strictures can develop when the thrombus involves jejunal veins, venous arcades or vasa recta. Read More

Urgent intraoperative endovascular stent placement to resolve acute hepatic or portal venous obstruction during liver surgery: a case series.

Surg Case Rep 2021 Jan 6;7(1). Epub 2021 Jan 6.

Department of Surgery, Fujita Health University, 1-98, Dengakugakubo, Kutsukake-cho, Toyoake, Aichi, 470-1192, Japan.

Background: Acute obstruction of the hepatic vein (HV) or the portal vein (PV), particularly when it occurs during liver surgery, is potentially fatal unless repaired swiftly. As surgical interventions for this problem are technically demanding and potentially unsuccessful, other treatment options are needed.

Case Presentation: We report two cases of acute, surgically uncorrectable HV or PV obstruction during liver resection or living donor liver transplantation (LDLT), which was successfully treated with urgent intraoperative placement of endovascular stents using interventional radiology (IVR).

Reliability of an ultrasonographical scoring system for diagnosis of sinusoidal obstruction syndrome/veno-occlusive disease in patients with hematopoietic stem cell transplantation.

J Med Ultrason (2001) 2021 Jan 4;48(1):45-52. Epub 2021 Jan 4.

Division of Laboratory and Transfusion Medicine, Hokkaido University Hospital, Sapporo, Japan.

Purpose: Sinusoidal obstruction syndrome (SOS)/hepatic veno-occlusive disease (VOD) is a fatal complication after hematopoietic stem cell transplantation. We previously reported the usefulness of an ultrasonographical (US) scoring system, the Hokkaido US-based scoring system consisting of ten parameters (HokUS-10): (1) hepatomegaly in the left lobe and (2) right lobe, (3) dilatation of the main portal vein (PV), (4) hepatofugal flow in the main PV, (5) decreased velocity of the PV, (6) dilatation of the para-umbilical vein (PUV), (7) appearance of blood flow signal in the PUV, (8) gallbladder (GB) wall thickening, (9) ascites, and (10) increased resistive index of the hepatic artery, for the diagnosis of SOS/VOD. However, the reliability of this system among operators remains elusive. Read More

Department of Surgery, University of Southern California, 1510 San Pablo Street, Suite 200, Los Angeles, CA 90033, USA; Pediatric Liver Transplant Program, Children's Hospital of Los Angeles, 4650 Sunset Boulevard, MS #147, Los Angeles, CA 90027, USA; Keck School of Medicine, University of Southern California, 1975 Zonal Avenue, Los Angeles, CA 90033, USA.

Background: Extrahepatic portal vein obstruction (EHPVO) causes portal hypertension in noncirrhotic children. Among surgical treatments, it is unclear whether the meso-Rex shunt (MRS) or portosystemic shunt (PSS) offers lower post-operative morbidity and superior patency over time. Our objective was to evaluate long-term outcomes comparing MRS and PSS for pediatric patients with EHPVO. Read More
