Intraoperative Normal Saline Administration and Acute Kidney Injury in Patients Undergoing Liver...
End Stage Liver DIseaseLiver Transplant; Complications1 moreThe investigators attempted to investigate the association of the type of crystalloid administered during liver transplantation with postoperative clinical outcomes. The investigators hypothesized that the greater amount of normal saline or half-saline administered during liver transplantation might be associated with the increased risk of acute kidney injury compared to the balanced crystalloids.
Totally Extraperitoneal Repair of Groin Hernia in Liver Transplanted Patients
Liver Transplant DisorderLiver Cirrhosis1 moreLiver transplant recipients share the risk with cirrhotic patients for the development of inguinal hernias, but their liver failure pathophysiology has reversed following transplantation. Despite immunosuppression alters wound healing and infections, inguinal hernia repair in transplanted patients has shown better outcome compared to cirrhotic patients. Endoscopic inguinal hernia techniques have proved to be superior to open repair, due to lower incidence of postoperative complications and short-term convalescence, but there is no evidence of the use of this approach in liver transplanted patients. This prospective consecutive case series study will be the first study to describe the postoperative results of groin hernia repair in ambulatory surgery regimen in liver transplanted patients using totally extraperitoneal approach. The included patients will be prospectively registered in a standardized database. Rate of completion of surgery by totally extraperitoneal approach without the needing of conversion to anterior open approach or transabdominal preperitoneal approach due technical difficulties will be evaluated. Postoperative complications all along with quality standards criteria of ambulatory surgery will be reported for descriptive purposes.
Mechanisms of Malnutrition in Cirrhosis With Portosystemic Shunting
CirrhosisCirrhosis is characterized by loss of muscle as well as fat mass, which increases morbidity and mortality before, during, and after liver transplantation. A common mechanism for the reduced muscle and fat mass in cirrhosis is an increased expression of the TGF (transforming growth factor)beta superfamily member, myostatin, in the muscle and adipose tissue. The present study will examine the expression of myostatin, its receptor and intracellular signaling pathways in the skeletal muscle and mesenteric adipose tissue in cirrhotic patients undergoing liver transplantation as compared to healthy controls undergoing planned abdominal surgery. 16 cirrhotic patients will be identified from the transplant list, and 16 healthy controls from outpatient surgery lists. Nutritional assessment will be performed, including anthropometry (triceps skinfold thickness, mid arm circumference), dual energy x-ray absorptiometry (DEXA), and bioelectrical impedance analysis (BIA). Rectus abdominis muscle tissue and omental fat tissue will be harvested in the operating room, and the expression of signaling proteins involved in skeletal muscle protein synthesis will be quantified. The investigator will also quantify the expression of genes involved in lipolysis and lipid synthesis. The investigator anticipates that the expression of myostatin will be higher in the skeletal muscle and adipose tissue of cirrhotics as compared to controls. There will be a reduction in the expression of the signaling proteins that regulate skeletal muscle protein synthesis, as well as the expression of genes regulating lipogenesis. The increased expression of myostatin will also correlate with reduced anthropometric and DEXA measurements of lean body mass and fat mass.

Magnetic Resonance Elastography as a Method to Estimate Stiffness of Soft Tissues
Heart FailureLiver Fibrosis2 moreMagnetic resonance elastography is a novel non-invasive MRI technique to obtain stiffness of soft tissues such as liver, heart, kidneys, etc. In this imaging technique a person is laid in an MR scanner and a paddle (plastic drum) is put on the area of interest to send sound vibration via a speaker placed outside the scan room which is connecting plastic drum via a plastic tube. These vibrations are scanned using MRI to estimate the stiffness of soft tissues such as liver, heart, kidneys, breast etc.
Endoscopic Ruler for the Assessment of Variceal Bleeding Risks (CHESS2005)
Liver CirrhosisPortal Hypertension1 moreThe presence of varices is a serious complication of portal hypertension in liver disease. To prevent variceal haemorrhage, screening and surveillance aims to detect high-risk varices related to varices size and determine the need for primary prophylaxis. Varices size evaluated by endoscopists might not be perfect reference, influenced by experience and machine. Endoscopic ruler is a novel tool to measure the varices size under the endoscopy. The investigators aim to evaluate the bias of varices size between endoscopists and endoscopic ruler as the reference.
Skeletal Muscle Parameters of Liver Cirrhosis in Non-invasive Imaging and Outcome
Liver CirrhosisThe principal aim of this study is to analyse L3-SMI (skeletal muscle index) in a cohort of patients with decompensated liver cirrhosis and TIPS (transjugular intrahepatic portosystemic shunt), and compare the prognostic power with TPMT (transverse psoas muscle thickness). Furthermore, the role of myosteatosis, determined in CT by L3-SMI, MRI and ultrasound will be studied.
