Decades of experience supports LDLT as a favorable strategy to reduce waitlist mortality. The multiple regenerative pathways of hepatocytes and other hepatic cells justify the rationale behind it. Nonetheless, living liver donation is still underused and its broader implementation is challenging, mostly due to variability in practices leading to concerns related to donor safety. A non-systematic literature search was conducted for peer-reviewed original articles related to pre-operative evaluation of living liver donor candidates...

Rat orthotopic liver transplantation (ROLT) serves as an ideal animal model and has gained popularity in addressing complications and perioperative treatments related to clinical liver transplantation. Through extensive research on ROLT model construction, the conventional "two-cuff" method has gradually become established. However, traditional methods still present challenges including limited visual field during vascular suturing, vascular torsion, biliary tract injuries, and prolonged anhepatic periods. Consequently, this paper aims to review the latest advancements and various techniques in this field, providing a valuable reference for individuals interested in constructing ROLT models...

Liver surgery is the cornerstone of the curative treatment of malignant liver tumors. However, the liver anatomy is very complex, and liver surgery is still associated with relevant morbidity despite many technical advances. The Brisbane nomenclature is used worldwide to classify liver resection. However, this nomenclature has several limitations as multiple terms are used for the same type of resection. Non-anatomical resections, multiple resections, and combined bilio-vascular resections were not mentioned...

BACKGROUND AND AIMS: Both nonalcoholic fatty liver disease (NAFLD) and cholelithiasis are highly prevalent hepatobiliary diseases with risk of progression into severe outcomes. Considering the close relationship between liver and gallbladder in anatomy and physiology, a potential causal relationship between NAFLD and cholelithiasis has been speculated. METHODS: Mendelian randomization (MR) was employed using genome-wide association study (GWAS) summary statistics in Million Veteran Program (MVP) for NAFLD, and statistics in UK biobank for cholelithiasis...

Surface electroenterography is a potential non-invasive alternative to current diagnostics of colonic motility disorders. However, electrode positioning in electroenterography is often based on general anatomy and may lack generalizability. Furthermore, the repeatability of electroenterography measurements is unknown. This study aimed to evaluate ultrasound-guided electrode positioning for electroenterography measurements and to determine the repeatability of those measurements. In ten healthy adults, two electroenterography procedures were performed, consisting of fasting, ultrasound-guided electrode localization and two 20-minute electroenterography recordings separated by a meal...

Most infections take place within three-dimensional host tissues with intricate anatomy and locally varying host physiology. The positioning of pathogen cells within this diverse environment significantly affects their stress levels, responses, fate, and contribution to the overall progression of the disease and treatment failure. However, due to the technical difficulties in locating µm-sized pathogen cells within cm-sized host organs, this area of research has been relatively unexplored. Here, we present a method for addressing this challenge...

Riedel's lobe of the liver is a rare anatomical variant often incidentally found on imaging or through the presence of hepatomegaly on physical examination. While patients are usually asymptomatic, the presentation of this condition can vary, ranging from nonspecific symptoms to more severe issues such as torsion, obstruction, rupture, and bleeding. We present a case of a patient with asymptomatic hepatomegaly who was incidentally found to have Riedel's lobe of the liver, accompanied by an elevated IgG mitochondrial antibody...

Endoscopic ultrasound (EUS)-guided liver biopsy is gaining popularity for liver parenchymal sampling due to its detailed visualization of liver anatomy, precision in sampling, and the ability to combine liver biopsy with other endoscopic goals. In this study, we present a case involving an anatomically complex, immunocompromised patient who underwent EUS-guided liver biopsy. While the samples were sufficient and progressed the management of her autoimmune hepatitis, her course was complicated by a multiloculated liver abscess...

Introduction The liver is the largest gland in the body and shows wide variation in surface features. Knowledge of external features is essential for radiological investigations and during abdominal surgeries. Morphological variation of the liver should be considered for better patient outcomes. Segmental anatomy has received more attention for segmental resection and transplant surgery. The present study aimed to determine variations in external features of the liver and indicate its clinical importance...

During the fetal period, oxygenated blood from the placenta flows through the umbilical vein (UV), portal sinus, ductus venosus (DV), and inferior vena cava (IVC) to the heart. This venous route varies regionally in many aspects. Herein, we sought to characterize the venous route's morphological features and regional differences during embryonic and early-fetal periods. Twenty-nine specimens were selected for high-resolution digitized imaging; 18 embryos were chosen for histological analysis. The venous route showed a primitive, large, S-shaped curved morphology with regional narrowing and dilation at Carnegie stage (CS) 15...

OBJECTIVE: Evaluation of the benefits of a virtual reality (VR) environment with a head-mounted display (HMD) for decision-making in liver surgery. BACKGROUND: Training in liver surgery involves appraising radiologic images and considering the patient's clinical information. Accurate assessment of 2D-tomography images is complex and requires considerable experience, and often the images are divorced from the clinical information. We present a comprehensive and interactive tool for visualizing operation planning data in a VR environment using a head-mounted-display and compare it to 3D visualization and 2D-tomography...

Due to the unique location and aggressive tumor biology,hilar cholangiocarcinoma,intrahepatic cholangiocarcinoma,and gallbladder cancer often present with obstructive jaundice and require extensive liver resection,also exhibit high rates of recurrence and metastasis after radical excision. Therefore,surgeons should make treatment decisions based on the biliary anatomy of patients and the biological characteristics of tumors as it significantly affects patient's prognosis. Treatment strategy should be made to ensure the successful implementation of radical resection for biliary tract malignant tumors while maximizing the survival benefits of patients...

This study aimed to improve the effectiveness of SEFS, a fixing solution composed of soap and ethanol. This was achieved by modifying the formulation of SEFS. Additionally, this study aimed to preserve the consistency of organs by perfusing cadavers with mixtures of gelatine-glycerin (gelatine-Gls) and gelatine-polyvinyl alcohol (gelatine-PVA) through vascular access. The modified SEFS embalmed cadavers were divided into two groups: Group I was treated with gelatine-glycerin, and Group II was treated with gelatine-polyvinyl alcohol and each group comprised of two goats and three rabbits...

Haemobilia, or bleeding within the biliary tree, is rare. It can cause biliary obstruction secondary to blood clots. A comorbid 87-year-old was admitted to hospital with acute cholecystitis, choledocholithiasis, and an Escherichia coli bacteremia. He had a partial pancreatectomy and gastrojejunostomy 35 years prior for severe pancreatitis. He was treated with antibiotics and a percutaneous cholecystostomy. He developed atrial fibrillation and was subsequently commenced on warfarin. He re-presented 5 days after discharge with abdominal pain and fevers...
