RATIONALE: With refinements in the operative technique, laparoscopic surgery has become the standard practice for liver resection. In the field of living donor liver transplantation, a few centers adopted laparoscopic surgery as an alternative to conventional open donor hepatectomy, and the application of pure laparoscopic donor right hepatectomy has been limited to the donors with simple, favorable biliary anatomy. PATIENT CONCERNS: The candidate donor was a 19-year-old woman with type 3a bile duct variation...

INTRODUCTION: Living donor liver transplantation (LDLT) is a technically demanding endeavor, requiring command of the complex anatomy of partial liver grafts. We examined the influence of anatomic variation and reconstruction technique on surgical outcomes and graft survival in the nine-center A2ALL Study. METHODS: Data from 272 adult LDLT recipients (2011-2015) included details on anatomic characteristics and types of intraoperative biliary reconstruction. Associations were tested between reconstruction technique and complications, which included first biliary complication ([BC]; leak, stricture, or biloma) and first vascular complication (hepatic artery thrombosis [HAT] or portal vein thrombosis [PVT])...

BACKGROUND: Near-infrared (NIR) fluorescence cholangiography by systemic administration of indocyanine green (ICG) enhances the visualization of the biliary tree anatomy. However, the simultaneous enhancement of liver parenchyma can disturb the visualization of critical details. We herein proposed a new technique of NIR cholecystocholangiography by intragallbladder ICG injection to increase the safety during laparoscopic cholecystectomy. METHODS: A total of 46 patients scheduled for laparoscopic cholecystectomy for symptomatic lithiasis (n = 21) or cholecystitis (n = 25) were enrolled...

PURPOSE: Portal vein embolization (PVE) is applied in patients with extended oncologic liver disease to induce hyperplasia of the future liver remnant and make resection feasible. Ultrasound (US) guidance is the gold standard for percutaneous portal vein access. This study evaluated feasibility and safety of C-arm cone beam computed tomography (CBCT) for needle guidance. MATERIALS AND METHODS: In 10 patients, puncture was performed under 3D needle guidance in a CBCT data set...

PURPOSE: Understanding anatomic and functional changes in the liver resulting from radiation therapy is fundamental to the improvement of normal tissue complication probability models needed to advance personalized medicine. The ability to link pretreatment and posttreatment imaging is often compromised by significant dose-dependent volumetric changes within the liver that are currently not accounted for in deformable image registration (DIR) techniques. This study investigated using delivered dose, in combination with other patient factors, to biomechanically model longitudinal changes in liver anatomy for follow-up care and re-treatment planning...

BACKGROUND: A 61-year-old man presented with upper abdominal pain and jaundice. Abdominal computed tomography imaging revealed stones in the gallbladder and the common bile duct, with a thickening of the gallbladder wall and an obvious increase in the volume of the gallbladder. Initial treatment using endoscopic retrograde cholangiopancreatography failed due to the presence of surgically altered gastrointestinal anatomy. Stones in the gallbladder and common bile duct were subsequently removed concurrently via percutaneous transhepatic papilla balloon dilatation combined with a percutaneous transcystic approach...

The liver is a vital organ with distinctive anatomy, histology and heterogeneous cell populations. These characteristics are of particular importance in maintaining immune homeostasis within the liver microenvironments, notably the biliary tree. Cholangiocytes are the first line of defense of the biliary tree against foreign substances, and are equipped to participate through various immunological pathways. Indeed, cholangiocytes protect against pathogens by TLRs-related signaling; maintain tolerance by expression of IRAK-M and PPARγ; limit immune response by inducing apoptosis of leukocytes; present antigen by expressing human leukocyte antigen molecules and costimulatory molecules; recruit leukocytes to the target site by expressing cytokines and chemokines...

When there is an anatomic anomaly in the biliary tract of the donor for living-donor liver transplantation, the risk of postoperative biliary tract complications increases in both the donor and the recipient. We studied a case of living-donor liver transplantation with a left hepatic lobe graft that had anatomic anomalies, in which the medial segmental branch (B4) joined the anterior segmental branch and the posterior segmental branch formed a common trunk with the lateral segmental branch. A 40-year-old man visited our institution as a candidate organ donor for his mother, who had end-stage liver failure...

OBJECTIVE: A fundamental aspect of surgical planning in liver resections is the identification of key vessel tributaries to preserve healthy liver tissue while fully resecting the tumor(s). Current surgical planning relies primarily on the surgeon's ability to mentally reconstruct 2D computed tomography/magnetic resonance (CT/MR) images into 3D and plan resection margins. This creates significant cognitive load, especially for trainees, as it relies on image interpretation, anatomical and surgical knowledge, experience, and spatial sense...

In the context of medical three-dimensional (3D) printing, in addition to 3D reconstruction from cross-sectional imaging, graphic design plays a role in developing and/or enhancing 3D-printed models. A custom prototype modular 3D model of the liver was graphically designed depicting segmental anatomy of the parenchyma containing color-coded hepatic vasculature and biliary tree. Subsequently, 3D printing was performed using transparent resin for the surface of the liver and polyamide material to develop hollow internal structures that allow for passage of catheters and wires...

INTRODUCTION: Liver is the largest abdominal organ located in right hypochondrium, epigastrium and left hypochondrium in upper abdominal cavity. Although the segmental anatomy of the liver has been extensively researched, very few studies have dealt with surface variations of the liver. The major fissures are important landmarks for interpreting the lobar anatomy and locating the liver lesions. AIM: To determine gross anatomical variations of liver and their clinical and surgical implications...

BACKGROUND: The evaluation of the hepatic vascular anatomy in living liver donors is increasingly being performed by three-dimensional (3D) computed tomography (CT) angiography. However, details of hepatic artery anatomy obtained by 3D CT angiography are not always superior to those obtained by angiography. Here, we report a case in which the 3D image navigation system helped to detect segment II, III, and IV arteries (A2, A3, and A4, respectively) that individually originated from the proper hepatic artery (PHA); this could not be detected by 3D CT angiography...

BACKGROUND: Intraoperative assessment of biliary tract anatomy is relevant for a number of benign and malignant hepatobiliary diseases. During biliary reconstruction, drainage of all relevant bile ducts is imperative to prevent atrophy of undrained segment, cholangitis and secondary biliary cirrhosis. Intraoperative cholangiography, though widely used for intraoperative imaging of the biliary tract, involves heavy equipment use, radiation risk and has a limited role in the evaluation of isolated segmental bile ducts...

BACKGROUND: Intestinal failure-associated liver disease (IFALD) causes significant morbidity in neonates with short bowel syndrome (SBS) dependent on parenteral nutrition (PN). Resected ileum, with loss of the ileocecal valve (ICV), is the most common anatomy in SBS, yet its impact on IFALD has not been adequately studied. METHODS: Neonatal piglets were randomized to 75% intestinal resection with jejunocolic anastomosis (JC, n = 12), 75% resection with jejunoileal anastomosis and intact ICV (JI, n = 13), PN-fed sham (sham, n = 14), or sow-fed control (SF, n = 8)...

BACKGROUND: Minimally invasive surgery has been validated to be a new standard in living donor hepatectomy for adult-to-pediatric transplantation with less morbidity [1]. Laparoscopic donor hepatectomy can reduce the major concerns about pain and morbidity associated with open surgery and a slow return to daily activities of donors [2]. Herein, we present one case of totally laparoscopic living donor left hepatectomy including the middle hepatic vein (MHV). DONOR AND METHOD: A 37-year-old mother volunteered to donate to her 3-year-old son with biliary atresia (PELD score 7)...
