In order to reduce the morbidity and mortality risk for the donor in living donor liver transplantation (LDLT), we previously identified 20% left portal vein (LPV) stenosis as the effective preconditioning to induce cell proliferation in the contralateral lobe without the downstream ipsilateral atrophy. We report, here, the pathways involved in the first hours after the preconditioning and investigate the changes in liver volume and function. Fourteen pigs entered this study. Five of them were used to study the genetic, cellular and molecular mechanisms set up in the early hours after the establishment of our preconditioning...

BACKGROUND: Liver regeneration involves hyperplasia and hypertrophy of hepatic cells. The capacity of macroscopic liver tissue to regenerate in ectopic sites is unknown. We aim to develop a novel in vivo model of ectopic liver survivability and regeneration and assess its functionality. METHODS: Adult male Sprague-Dawley rats (n = 23) were divided into four groups: (1) single-stage (SS) group, wedge liver resection was performed, and the parenchyma was directly implanted into the omentum; (2) double-stage (DS) group, omentum pedicle was transposed over the left hepatic lobe followed by wedge liver resection along with omental flap; (3) Biogel + DS group, rats received intraperitoneal injection of inert polymer particles prior to DS; (4) Biogel + DS + portal vein ligation (PVL) group, Biogel + DS rats underwent subsequent PVL...

Intestinal malrotation displays classic pattern of the small bowel activity on hepatobiliary scintigraphy that could lead to the diagnosis, but only if an interpreting physician looks for it. Presented are 2 cases, one demonstrates diagnostic findings during the first 60-minute phase, whereas the other reveals the diagnosis only on the later sincalide stimulation phase. The currently recommended structured reporting for hepatobiliary scintigraphy does not include examination of bowel activity pattern, which could result in a missed diagnosis...

AIM: Perihilar cholangiocarcinoma (PHC) is a challenging disease and requires aggressive surgical treatment in order to achieve curation. The assessment and work-up of patients with presumed PHC is multidisciplinary, complex and requires extensive experience. The aim of this paper is to review current aspects of diagnosis, preoperative work-up and extended resection in patients with PHC from the perspective of our own institutional experience with this complex tumor. METHODS: We provided a review of applied modalities in the diagnosis and work-up of PHC according to current literature...

While imaging studies such as computed tomography or magnetic resonance imaging allow the volumetric assessment of the liver segments, only indirect information is provided concerning the quality of the liver parenchyma and its actual functional capacity. Assessment of liver function is therefore crucial in the preoperative workup of patients who require extensive liver resection and in whom portal vein embolization is considered. This review deals with the modalities currently available for the measurement of liver function...

Background: ALPPS (associating liver partition and portal vein ligation for staged hepatectomy) was introduced with the promise to reduce posthepatectomy liver failure (PHLF) in extended hepatectomies but has higher morbidity and mortality rates compared to conventional methods of volume enhancement. There are few studies of the incidence of PHLF after ALPPS and little information on how to avoid PHLF by functional testing. It remains unclear what causes the compromise in liver function despite rapid volume gain and if any of the modifications proposed reduce the incidence of PHLF...

Portal vein embolization (PVE) was first adapted for patients undergoing major hepatectomy for hepatocellular carcinoma (HCC). In these patients, PVE caused hypertrophy of the unaffected liver and increased the volumetric ratio of future liver remnant (FLR) to total liver volume.99m Technetium-galactosyl human serum albumin (99m Tc-GSA) scintigraphy revealed that PVE also induced a shift in hepatic function from the embolized part to the nonembolized part of the liver. Various hepatobiliary malignancies can be treated using PVE, and PVE is increasingly being used to expand the indication for major hepatectomy in patients with initially insufficient FLR volume or function...

The biodistribution of dendronized iron oxides, NPs10@D1_DOTAGA and melanin-targeting NPs10@D1_ICF_DOTAGA, was studied in vivo using MRI and planar scintigraphy through [177Lu]Lu-radiolabeling. MRI experiments showed high contrast power of both dendronized nanoparticles (DPs) and hepatobiliary and urinary excretions. Little tumor uptake could be highlighted after intravenous injection probably as a consequence of the negatively charged DOTAGA-derivatized shell which reduces the diffusion across the cells' membrane...

Selective portal vein ligation (PVL) allows the two-stage surgical resection of primarily unresectable liver tumours by generating the atrophy and hypertrophy of portally ligated (LL) and non-ligated lobes (NLL), respectively. To evaluate critically important underlying functional alterations, present study characterised in vitro and vivo liver function in male Wistar rats (n = 106; 210-250 g) before, and 24/48/72/168/336 h after PVL. Lobe weights and volumes by magnetic resonance imaging confirmed the atrophy-hypertrophy complex...

Duodeno-gastro-esophageal reflux, or bile reflux, is a condition for which there is no diagnostic gold standard, and it remains controversial in terms of carcinoma risk. This is pertinent in the context of an increasingly overweight population who are undergoing weight-loss operations that theoretically further increase the risk of bile reflux. This article reviews investigations for bile reflux based on efficacy, patient tolerability, cost, and infrastructure requirements. At this time, whilst no gold standard exists, hepatobiliary scintigraphy is the least invasive investigation with good-patient tolerability, sensitivity, and reproducibility to be considered first-line for diagnosis of bile reflux...

Spontaneous perforation of extrahepatic biliary system is a rare and potentially fatal cause of acute abdomen. Clinical presentation is as biliary peritonitis. This condition is rarely suspected as a cause of peritonitis preoperatively and correct diagnosis is made during surgery. If suspected, diagnosis can be made by various imaging techniques like hepatobiliary scintigraphy, magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiopancreatography (ERCP). As these imaging techniques are not readily available, especially in low socioeconomic countries, we hereby report a case of spontaneous common bile duct (CBD) perforation, which was diagnosed preoperatively by estimation of ascitic fluid-to-serum bilirubin ratio, a simple, quick, and cost-effective test...

BACKGROUND: Twenty percent of cholecystectomies in the US are performed for a diagnosis of biliary dyskinesia. Diagnosis is made by measuring gallbladder ejection fraction (GbEF) using hepatobiliary scintigraphy. Our purpose was to evaluate the reproducibility of GbEF measurements. STUDY DESIGN: This is a retrospective review of patients referred for cholecystectomy, from 2010 to 2016, with a diagnosis of biliary dyskinesia based on a GbEF test, who then underwent a repeat GbEF test...

Bronchobiliary fistula (BBF), a rare complication of liver disease, is an abnormal communication between the biliary tract and bronchial tree. BBF may occur as a consequence of local liver infections such as hydatid or amebic disease, pyogenic liver abscess or trauma to the liver, obstruction of biliary tract, and tumor. As such management of liver disease with BBF is very difficult and often associated with a high rate of morbidity and mortality. Therefore, timely diagnosis of BBF is imperative. Hepatobiliary scintigraphy along with hybrid single photon emission computed tomography/computed tomography using Tc99m-mebrofenin is a very useful noninvasive imaging modality, in the diagnosis of BBF...

INTRODUCTION: Recently, there has been increasing interest in the preoperative prediction and prevention of post-hepatectomy liver failure (PHLF). This is a particular concern in colorectal liver metastases (CRLM), when surgery follows potentially hepatotoxic chemotherapy. Platelet-based liver scores (PBLS) such as APRI and FIB-4 are predictive of chemotherapy-associated liver injury (CALI) and PHLF. Estimation of the future liver remnant function (eFLRF) by combining99m Tc-Mebrofenin Hepatobiliary Scintigraphy (HBSBSA ) with future liver remnant volume ratio (FLRV%), is predictive of PHLF and related mortality...

OBJECTIVE: Suspected sphincter of Oddi dysfunction (SOD) is a well-known risk factor for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). The indication of ERCP for suspected SOD patients was very low in Japan compared to other countries. Therefore, the risk of PEP may be different in Japanese SOD patients. The objective of this study was to evaluate the risk of PEP in suspected biliary type SOD in Japan. METHODS: From December 1996 to January 2017, 72 patients were suspected as having biliary type SOD, by questionnaire, liver function tests, hepatobiliary scintigraphy, abdominal ultrasonography, upper gastrointestinal endoscopy, endoscopic ultrasonography and magnetic resonance cholangiopancreatography...

PURPOSE: Hepatobiliary scintigraphy (HBS) is used to aid in the diagnosis of Biliary Atresia in full-term infants with conjugated hyperbilirubinemia. There is little information on the utility of the HBS in premature infants with conjugated hyperbilirubinemia and infants with parenteral nutrition associated cholestasis (PNAC). The purpose of this study is to assess the utility of HBS in differentiating Biliary Atresia and PNAC in premature neonates and full-term infants who received parenteral nutrition (PN)...
