Selection of Safe Donors for Living Donor Liver Transplant Using Extended Right Lobe Graft.

Extended right lobectomy (ERL) for living donor liver transplant (LDLT) is selectively performed in many transplant centers and has shown excellent recipient outcomes as reported in previous studies. Yet, there is no universally accepted indication for ERL in respect to donor safety. Current study was designed to stratify risk factors of adverse donor outcome after ERL.

Incidence, mortality, and survival of liver cancer using Korea central cancer registry database: 1999-2019.

Backgrounds/aims: Historically, incidence and survival analysis and annual traits for primary liver cancer (LC) has not been investigated in a population-based study in Korea. The purpose of the current study is to determine incidence, survival rate of patients with primary LC in Korea.

Methods: We conducted a retrospective cohort study using Korea Central Cancer Registry based on the Korea National Cancer Incidence Database.

A Complication of Diaphragm Repair Using a Gore-Tex (Expanded Polytetrafluorethylene) Membrane: A Case Report.

A 65-year-old man underwent right trisectionectomy of the liver and reconstruction of the chest wall and diaphragm with a 2-mm Gore-Tex membrane due to recurrent hepatocellular carcinoma. After 3 years, the Gore-Tex membrane in the diaphragm migrated to the abdominal cavity and perforated the colon. We report a rare complication of a Gore-Tex membrane after diaphragm repair.

Systemic Immune-Inflammatory Marker of High Meld Patients Is Associated With Early Mortality After Liver Transplantation.

The scarcity of deceased donor livers has led to allocation of grafts to only the most seriously ill patients with a high Model for End-Stage Liver Disease (MELD) score, which has resulted in a high mortality rate after deceased donor liver transplantation (DDLT). The aim of this study is to identify risk factors for posttransplant mortality and thereby reduce futile outcomes in DDLT. Between 2013 and 2019, 57 recipients with MELD scores ≥30 underwent DDLT in our center.

Strategy for Selective Middle Hepatic Vein Reconstruction in Living Donor Liver Transplantation Using Right Lobe Graft: A Retrospective Observational Study.

Background: The aim of this study was to verify the safety and feasibility of our selection criteria for middle hepatic vein (MHV) reconstruction in living donor liver transplantation (LDLT) using right lobe grafts.

Methods: A total of 153 LDLTs were performed using right lobe grafts in a tertiary hospital from 2006 to 2016. Among them, 52 cases without MHV reconstruction were compared with 101 recipients who underwent LDLT using right lobe graft with MHV reconstruction.

Risk Factors for Beyond Milan Recurrence After Hepatic Resection for Single Hepatocellular Carcinoma No Larger Than 5 Centimeters.

Hepatic resection (HR) is considered a treatment of choice for a single hepatocellular carcinoma (HCC) ≤5 cm in patients with preserved liver function. However, it is possible for these patients to develop a severe form of recurrence (beyond Milan recurrence [BMR] criteria). This recurrence could have been avoided if liver transplantation (LT) was performed primarily, as LT is believed to yield a more favorable oncological outcome compared with HR.

Prognostic value of advanced lung cancer inflammation index in patients with colorectal cancer liver metastases undergoing surgery.

Introduction: Recently, a new inflammatory marker, the advanced lung cancer inflammation index (ALI), was reported as a prognostic marker in patients with several cancers. We aimed to investigate the prognostic value of ALI in patients with colorectal cancer liver metastases (CLM) undergoing surgery.

Methods: From June 2009 to June 2018, 141 patients underwent a surgery for CLM at Ajou University Hospital, of whom 132 without extrahepatic metastases, systemic inflammatory diseases, or immune system diseases were enrolled in this study.

F-fluorodeoxyglucose PET/CT as an independent predictor for patients with hepatocellular carcinoma combined with major portal vein tumor thrombus.

Purpose: Hepatocellular carcinoma (HCC) patients with major portal vein tumor thrombosis (mPVTT) complications were generally characterized by extremely poor prognoses. The aim of this study was to explore the role of F-fluorodeoxyglucose (F-FDG) PET/CT imaging in predicting HCC complicated by mPVTT.

Methods: Five hundred one HCC patients received surgery in our hospital during November 2008 to December 2014, among which 32 patients (6.

Can we delineate preoperatively the right and ventral margins of caudate lobe of the liver?

Purpose: Complete removal of the caudate lobe, which is sometimes necessary, is accomplished via isolated caudate lobectomy or hepatectomy that includes the caudate lobe. It is impossible, however, to confirm the right and ventral margins of the caudate lobe by preoperative imaging. This study was undertaken to determine whether we could identify the right and ventral margins of the caudate lobe preoperatively using Synapse 3D visualization software.

Molecular classification of hepatocellular adenoma: A single-center experience.

Backgrounds/aims: Hepatocellular adenoma (HCA) is a rare benign tumor that has a risk of malignant transformation into hepatocellular carcinoma (HCC) and bleeding. The aim of this study was to analyze the characteristics of HCA by performing molecular classification.

Methods: We retrospectively collected data from nine patients who were diagnosed with HCA from 1995 to 2016.

The 7th/8th American Joint Committee on Cancer and the Modified Union for International Cancer Control Staging System for Hepatocellular Carcinoma.

Purpose: Although many staging systems have been proposed for hepatocellular carcinoma (HCC), there is no globally accepted system due to the extreme heterogeneity of the disease. We aimed to compare the results of the 7th/8th American Joint Committee on Cancer (AJCC) and the modified Union for International Cancer Control (mUICC) staging systems in patients with HCC.

Materials And Methods: We collected data from 792 patients who underwent hepatic resection at our center.

Longterm Analysis of Biliary Complications After Duct-to-Duct Biliary Reconstruction in Living Donor Liver Transplantations.

Biliary complication (BC) is still regarded as the Achilles' heel of a living donor liver transplantation (LDLT). This study aims to evaluate the longterm outcomes of the duct-to-duct (DD) biliary reconstruction using 7-0 suture and to identify the risk factors of BCs after LDLTs. Data of 140 LDLTs between 2006 and 2015 were analyzed.

Surgical treatment for hepatocellular carcinoma with bile duct invasion.

Purpose: There is still some debate on surgical procedures for hepatocellular carcinoma (HCC) patients with bile duct tumor thrombi (BDTT, Ueda type 3 or 4). What is adequate extent of liver resection for curative treatment? Is extrahepatic bile duct resection mandatory for cure? The aim of this study is to answer these questions.

Methods: Between February 1994 and December 2012, 877 consecutive HCC patients underwent hepatic resection at Ajou University Hospital.

Risk factors for parastomal hernia: based on radiological definition.

Purpose: The aim of this study was to investigate the clinical and radiological incidence of parastomal hernia and to analyze the risk factors for parastomal hernia.

Methods: We reviewed retrospectively 108 patients with end colostomy from January 2003 to June 2010. Age, sex, surgical procedure type, body mass index (kg/m(2)), stoma size, and respiratory comorbidity were documented.

Routine barium enema prior to closure of defunctioning ileostomy is not necessary.

Purpose: The use of barium enemas to confirm the anastomotic integrity prior to ileostomy closure is still controversial. The purpose of the study was to determine the utility of routine contrast enema prior to ileostomy closure and its impact on patient management in patients with a low pelvic anastomosis.

Methods: One hundred forty-five patients had a temporary loop ileostomy constructed to protect a low colorectal or coloanal anastomosis following low anterior resection for rectal cancer.

Kidney transplantation from a donor following cardiac death supported with extracorporeal membrane oxygenation.

To expand the donor pool, organ donation after cardiac death (DCD) has emerged. However, kidneys from DCD donors have a period of long warm ischemia between cardiac arrest and the harvesting of the organs. Recently, we used extracorporeal membrane oxygenation (ECMO) to minimize ischemic injury during 'no touch' periods in a Maastricht category II DCD donor and performed two successful kidney transplantations.

Laparoscopic enucleation of a bladder leiomyoma.

Bladder leiomyomas account for less than 0.43% of all bladder tumors, and these comprise about 35% of mesenchymal tumors [1,2]. About 250 cases of bladder leiomyoma have been reported in the English literature to date [3].
