Incidence of superficial left hepatic vein and its usability for graft hepatic vein venoplasty in pediatric liver transplantation.

Backgrounds: The anatomy of the left hepatic vein (LHV) is variable; thus, it should be considered for graft hepatic vein (GHV) venoplasty for left lateral section (LLS) and left liver grafts. This study assessed the incidence of superficial LHV (sLHV) branches according to LHV anatomy and its usability for GHV venoplasty in pediatric liver transplantation (LT).

Methods: This study consisted of three parts: (1) anatomical classification of LHV variations and the incidence of sLHV branches; (2) morphometric simulative analysis of GHV reconstruction and (3) clinical application based on LHV anatomy.

Effects of Virtual Reality-Based Cognitive Training in the Elderly with and without Mild Cognitive Impairment.

Objective: This study aimed to introduce a 4-week long fully immersive virtual reality-based cognitive training (VRCT) program that could be applied for both a cognitively normal elderly population and patients with mild cognitive impairment (MCI). In addition, we attempted to investigate the neuropsychological effects of the VRCT program in each group.

Methods: A total of 56 participants, 31 in the MCI group and 25 in the cognitively normal elderly group, underwent eight sessions of VRCT for 4 weeks.

Cognitive reserve and the effects of virtual reality-based cognitive training on elderly individuals with mild cognitive impairment and normal cognition.

Background: Cognitive reserve (CR) is a concept proposed to account for discrepancies between the extent of brain pathology and clinical manifestations of that pathology. This study aimed to explore the associations between CR and the effects of cognitive training using fully immersive virtual reality (VR).

Methods: A total of 44 older adults (22 cognitively normal, 22 with mild cognitive impairment) underwent eight cognitive training sessions using VR for a period of 4 weeks.

Outflow vein venoplasty of left lateral section graft for living donor liver transplantation in infant recipients.

The orifice size of the LHV trunk in LLS grafts is often too small for direct anastomosis. Several methods were developed to enlarge the graft and recipient hepatic vein orifices. This study described our surgical techniques to secure hepatic vein reconstruction in infant recipients and analyzed the patency outcomes.

Portal vein reconstruction using side-to-side unification technique for infant-to-infant deceased donor whole liver transplantation.

Backgrounds/aims: Infant-to-infant whole liver transplantation (I2I-WLT) has been rarely performed in Korea. We analyze clinical sequences of our 7 cases of I2I-WLT and present evolution of surgical techniques to prevent PV stenosis.

Methods: A total of 7 cases of I2I-WLT were performed at our institution during last 13 years, which represented 0.

Risk Estimation for Biliary Atresia in Patients with Neonatal Cholestasis: Development and Validation of a Risk Score.

Purpose To develop and validate a scoring system based on clinical and imaging features to predict the risk for biliary atresia in patients with neonatal cholestasis. Materials and Methods Patients with neonatal cholestasis who underwent both ultrasonography (US) and hepatobiliary scintigraphy (n = 480) were retrospectively identified from two tertiary referral hospitals from January 2000 to February 2017. Patients from one hospital were classified as the derivation cohort (n = 371), and those from the other hospital were classified as the validation cohort (n = 109).
