Evaluating histone H3.1 as a biomarker for acute ischemic stroke: insights into NETs and stroke pathophysiology.

The diagnosis of acute ischemic stroke (AIS) can be challenging when neuroimaging findings are normal or equivocal. Neutrophil extracellular traps (NETs), particularly histone H3.1, have potential as biomarkers for AIS.

The Pancreas After Kidney Transplant is a Competitive Option, Comparable to the Simultaneous Pancreas and Kidney Transplant.

Background: Simultaneous pancreas and kidney transplant (SPK) is the most common type of pancreas transplant performed worldwide. In contrast, there are a few drawbacks to pancreas after kidney transplant (PAK), such as the requirement for an additional operation, the immunologic risk, etc. SPK is the best option, but because of a lack of deceased donors and a lengthy waiting period, it is not always possible to use it.

Modification of Venous Outflow to Avoid Thrombotic Graft Failure in Pancreas Transplantation.

BACKGROUND Even with recent data, 5-10% of pancreas transplants experience early technical failure. Graft thrombosis is the primary cause of early technical failure, even when only optimal grafts are used, as is the case in Korea. The purpose of this study was to determine whether we can avoid thrombotic graft failure by modifying venous outflow.

Technical factors that minimize the occurrence of early graft failure in pancreas transplantation.

Pancreatic transplantation is the only treatment for insulin-dependent diabetes resulting in long-term euglycemia without exogenous insulin. However, pancreatic transplantation has become debatable following the improvements in the results of islet transplantation and artificial pancreas. Therefore, surgeons who perform pancreas transplants require the best surgical technique that can minimize technical failure.

ABO-Incompatible Living Donor Liver Transplantation With a Simplified Desensitization and Immunosuppression Protocol: A Single-Center Retrospective Study.

Objectives: New desensitization strategies have made ABO-incompatible living donor liver transplant an attractive option for patients with end-stage liver disease. We aimed to report our experience with 20 consecutive patients who underwent ABO-incompatible living donor liver transplant using a simplified desensitization and immunosuppression regimen.

Materials And Methods: We retrospectively analyzed 20 ABO-incompatible living donor liver transplant cases (August 2015 to July 2019).

Successful defibrotide treatment of a patient with veno-occlusive disease after living-donor liver transplantation: A case report.

Rationale: Veno-occlusive disease (VOD) is characterized by painful hepatomegaly, ascites, weight gain, and jaundice with nonthrombotic, fibrous obliteration of the centrilobular hepatic veins. VOD after liver transplantation is a rare complication, with an incidence of approximately 2%; however, it can be life-threatening in severe cases. The precise etiology and mechanism of VOD after liver transplantation remains unclear.

Usefulness of Preoperative Magnetic Resonance Spectroscopy to Improve the Safety of a Living Liver Donor.

Objectives: The steatosis of graft liver is an important factor in liver transplant that determines the graft function in the recipient and the recovery of the remnant liver in the living donor. We analyzed the data of living donors from our center to evaluate whether magnetic resonance imaging and magnetic resonance spectroscopy can replace liver biopsy.

Materials And Methods: From May 2010 to May 2019, data from a total of 239 living donors was collected.

Epidermoid cyst in an intrapancreatic accessory spleen in the pancreas head: a case report.

Background: An epidermoid cyst in an intrapancreatic accessory spleen (ECIPAS) in the pancreas head is an extremely rare condition. The natural course of this condition is not well known, and it is difficult to diagnose before surgery due to the lack of specific imaging findings.

Case Presentation: A tumor was found in the head of the pancreas in a 68-year-old man with abdominal distension and discomfort.

Efficacy and Safety of Weight Reduction of the Donor in Hepatic Steatosis for Living Donor Liver Transplantation.

BACKGROUND Use of steatotic livers is a known risk factor for increased primary nonfunction after liver transplantation. This study investigated the efficacy and clinical outcome of simple weight reduction of steatosis for donors undergoing living-donor liver transplantation (LDLT). MATERIAL AND METHODS We defined two groups: the reduction group, which included donors with >30% macrovesicular steatosis and body mass index (BMI) >25 kg/m², and the conventional group, which included donors with.

Liver Transplant Patients with High Preoperative Serum Bilirubin Levels Are at Increased Risk of Postoperative Delirium: A Retrospective Study.

Postoperative delirium is a common complication after liver transplantation (LT). A high model for end-stage liver disease (MELD) score is an independent risk factor for postoperative delirium, but it is unclear which of the components of this score are risk indicators. The aim of this study was to analyze the incidence of postoperative delirium according to the preoperative serum bilirubin level, a component of the MELD score, in patients who underwent LT.

Eosinophil-to-monocyte ratio is an excellent predictor of acute cellular rejection in pancreas transplant alone recipients.

Serum pancreatic enzymes (serum amylase and lipase) are sensitive markers for monitoring acute rejection in pancreatic transplant recipients. However, those enzymes are not specific, as their levels are elevated in other conditions. We evaluated the eosinophil-to-monocyte ratio (EMR) in peripheral blood as a biomarker of acute rejection in the clinical setting in recipients of pancreatic transplant alone.

Progression of diabetic nephropathy after successful pancreas transplantation alone: a case report.

Pancreas transplantation is the only method that can nearly cure insulin-dependent diabetes mellitus. However, the effect of pancreas transplantation on patients with diabetic nephropathy has recently been considered controversial. In this report, we present a case of abrupt aggravation of proteinuria after successful pancreas transplantation alone without evidence of calcineurin inhibitor (CNI) toxicity.

Outcomes of liver resection in patients with colorectal liver metastases by laparoscopic or open surgery.

Backgrounds/aims: Colorectal cancer is found with liver metastases about 20-25% due to characteristics of cancer itself. Approximately 20% of liver metastases are found to be resectable. The objective of this study was to evaluate short-term outcomes of patients who received liver resection with colorectal cancer operation in our center by laparoscopic surgery or open surgery.

Two cases of bronchobiliary fistula: Case report.

A bronchobiliary fistula, or a biliobronchial fistula (BBF), is a rare condition. It results from an abnormal connection between the biliary and bronchial trees, and is characterized by pathognomonic bilious sputum with suspicious pneumonia. Traditionally, an infectious disease, such as a hydatid infection, has been known to cause a BBF, but BBFs have recently become associated with tumors.

A comparison of desensitization methods: Rituximab with/without plasmapheresis in ABO-incompatible living donor liver transplantation.

Background: Plasmapheresis is a desensitization method used prior to ABO-incompatible (ABO-I) living donor liver transplantation. However, studies on its usefulness in the rituximab era are lacking.

Methods: Fifty-six adult patients underwent ABO-I living donor liver transplantation between January 2012 and October 2015.

Prognostic significance of F-FDG PET/CT in patients with colorectal cancer liver metastases after hepatectomy.

Introduction: Colorectal cancer liver metastasis (CRLM) can be cured with surgery. To improve survival, optimal selection of CRLM patients should be done cautiously, which may be facilitated by preoperative [F-18] fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT).

Methods: A total of 245 patients with CRLM between February 2007 and January 2015 were retrospectively studied.

Are you prepared for pancreas bifidum? A case report.

Pancreas divisum-failure of fusion of the dorsal and ventral pancreatic ducts-is relatively well known as the most common congenital anomaly of the pancreatic duct, of with an incidence approximately 10% of all embryos. And there is a rare anomaly similar to pancreas divisum in which doubled ducts are formed. This condition is a rare developmental anomaly called pancreas bifidum or bifid pancreas or fish tail pancreas.

Perioperative transfusion in pancreatoduodenectomy: The double-edged sword of pancreatic surgeons.

We designed the study to clarify the prognostic significance of perioperative (preoperative, intraoperative, and postoperative) red blood cell (RBC) transfusion following pancreaticoduodenectomy (PD) for periampullary cancers.This study retrospectively analyzed 244 periampullary cancer patients (pancreatic cancer, 124 patients; bile duct cancer, 63 patients; and ampullary cancer, 57 patients) treated by PD from June 2001 to June 2010 at the National Cancer Center, Korea (NCC2017-0106).A total of 112 (46%) of 244 patients had received transfusion (preoperative, 5%; intraoperative, 17%; and postoperative, 37%).

A simplified protocol using rituximab and immunoglobulin for ABO-incompatible low-titre living donor liver transplantation.

Background & Aims: No consensus has been reached regarding optimal treatment strategies for ABO-incompatible (ABO-I) living donor liver transplantation (LDLT). We introduce a simplified protocol using rituximab and intravenous immunoglobulin (IVIG).

Methods: Data were analysed on adult patients who underwent ABO-I LDLT of which protocol added rituximab (300 mg/m ) before surgery and IVIG (0.

Small-for-size grafts increase recurrence of hepatocellular carcinoma in liver transplantation beyond milan criteria.

Living donor liver transplantation (LDLT) has been reported to have high rates of hepatocellular carcinoma (HCC) recurrence compared with deceased donor liver transplantation (DDLT). This has been assumed to be due to the frequent use of small-for-size grafts (SFSGs) in LDLT rather than DDLT, but the relationship between graft size and prognosis remains controversial. This study aimed to clarify the effect of SFSGs on the oncologic outcomes of patients with HCC who underwent LDLT.

Risk prediction of post-hepatectomy liver failure in patients with perihilar cholangiocarcinoma.

Background And Aim: In most patients with perihilar cholangiocarcinoma (PHCC), major hepatectomy and extrahepatic bile duct resection are needed for surgical radicality, and a high risk of hepatic insufficiency exists. This study aims to develop a prediction model for post-hepatectomy liver failure (PHLF) in patients with PHCC.

Methods: A total of 143 patients who underwent major liver resection and extrahepatic bile duct resection for PHCC between October 2001 and December 2013 were included.
