Right hepatectomy: mishaps of extra-hepatic portal vein division.

Published: October 2022

En-bloc clamping of the hepatic pedicle is commonly performed during liver resection in order to reduce bleeding during parenchymal transection. Selective vascular clamping of the ipsilateral portal vein branch and artery is considered preferable to avoid ischemia-reperfusion injury to the future liver remnant and there has as yet been no reports of serious morbidity related to this technique. Herein we report three adverse incidents associated with attempts at extrahepatic control and division of the right portal vein during hepatectomy. Although extrahepatic control of the right portal vein is simple in a majority of patients caution is advised in the presence of anatomical variations of the right portal vein, liver dysmorphia, preoperative portal vein embolization and during the learning curve of laparoscopic liver resection. A Pringle maneuver may be preferable to hemihepatic inflow occlusion for repeat hepatectomies.

Background: Liver cirrhosis accounts for more than 90 % of portal hypertension cases, and the other cases are due to noncirrhotic portal hypertension (NCPH). Variceal bleeding is the most life-threatening complication of portal hypertension and its primary treatment is medical according to the Baveno VII guidelines. This review discusses the evidence on surgical portal decompression for adult patients with NCPH secondary to chronic extrahepatic portal vein obstruction (EHPVO).

A conceptual mechanistic model of amino acid fluxes in the small intestine, taking the example of pig.

PEGASE, INRAE, Institut Agro, 35590 Saint Gilles, France. Electronic address:

During digestion, almost 50% of absorbed essential amino acids (AAs) are metabolised by intestinal tissue, thus not appearing directly in the portal vein. This value, which is referred to as first-pass metabolism, seems high in relation to the overall efficiency of AA use considered in growth models. Experimental studies of first-pass metabolism are complicated due to the presence of numerous metabolic fluxes in the intestine and to the dynamics of digestion and absorption.

This in vivo study introduces a newly developed spirooxindole derivative that is deemed safe and effective as a potential targeted therapy for various cancers. Extensive in vivo investigations, including histopathology, immunohistochemistry, and molecular biology, validated its potential for further preclinical and clinical exploration, necessitating comprehensive examinations of its bioavailability, pharmacodynamics, and pharmacokinetics. Additionally, this study involves the development of a commercially viable proniosomal drug delivery system for the compound, facilitating controlled drug release.

Background: Portal vein thrombosis (PVT) leads to portal hypertension (PH) with its sequelae. Computed tomography spleno-mesenterico-portography (CT-SMPG) combines sequential CT spleno-portography and CT mesenterico-portography. CT-SMPG comprehensively illustrates the venous hemodynamic changes due to PH.

Hepatic encephalopathy (HE) in dogs is a metabolic disorder of the central nervous system that occurs secondarily to liver dysfunctions, whether due to acquired or congenital causes. A portosystemic shunt is the presence of abnormal communications between the hepatic vessels (portal and suprahepatic veins). As a result of this, the blood brought from the digestive tract through the portal vein bypasses the liver, and the unmetabolized components of the portal bloodstream enter directly into systemic circulation, causing clinical symptoms of metabolic encephalopathy (HE).
