Due to the shortage of liver allografts and the rising prevalence of fatty liver disease in the general population, steatotic liver grafts are considered for transplantation. This condition is an important risk factor for the outcome after transplantation. We here analyze the characteristics of the donor pool offered to the Charité - Universitätsmedizin Berlin from 2010 to 2016 with respect to liver allograft nonacceptance and steatosis hepatis. Of the 2653 organs offered to our center, 19.9% (n=527) were accepted for transplantation, 58...

BACKGROUND: One-third of 5-year survivors after liver resection for colorectal liver metastases (CLM) develop recurrence or tumor-related death. Therefore 10-year survival appears more adequate in defining permanent cure. The aim of this study was to develop prognostic models for the prediction of 10-year survival after liver resection for colorectal liver metastases. METHODS: N=965 cases of liver resection for CLM were retrospectively analyzed using univariable and multivariable regression analyses...

BACKGROUND: Since local tumor infiltration to the mesenteric-portal axis might represent a challenging assignment for curative intended resectability during pancreatic surgery, appropriate techniques for venous reconstruction are essential. In this study, we acknowledge the falciform ligament as a feasible and convenient substitute for mesenteric and portal vein reconstruction with high reliability and patency for local advanced pancreatic tumor. METHODS: A retrospective single-center analysis...

OBJECTIVE: We are trying to investigate the possibility, safety, and benefits of replacing the role of T-tube by another more safe and effective procedure for biliary decompression in the case of common bile duct (CBD) exploration. METHODS: Our present study includes fifty consecutive patients who underwent a traditional CBD exploration due to choledocholithiasis. Patients were divided into 2 equal groups. In the 1st group, a spontaneously expelled Nelaton tube is placed in the CBD to aid in bile drainage to the duodenum, while in the 2nd group, a conventional T-tube is placed to decompress the CBD in the early postoperative (PO) days to a drainage bag...

INTRODUCTION: The success of liver transplantation has been limited by the unavailability of suitable donor livers. The current organ preservation technique, i.e., static cold storage (SCS), is not suitable for marginal organs. Alternatively, normothermic machine perfusion (NMP) promises to recreate the physiological environment and hence holds promise for the better organ preservation. The objective of this systematic review is to provide an overview of the safety, benefits, and insight into the other potential useful parameters of NMP in the liver preservation...

Background: Plexiform neurofibroma (PNF) in the porta hepatis (PH) is an unusual manifestation of neurofibromatosis-1 (NF-1). Resection is often recommended given the risk of malignant transformation. We encountered a challenging case in clinical practice which prompted us to report our findings and perform a systematic review on the management of these tumors. Methods: We reported the case of a 31-year-old woman with NF-1 and PNF of the PH. PRISMA 2009 guidelines were followed for systematic review...

As a result of donation after circulatory death liver grafts' poor tolerance to cold storage, there has been increasing research interest in normothermic machine perfusion. This study aims to systematically review the current literature comparing normothermic perfusion to cold storage in donation after circulatory death liver grafts and complete a meta-analysis of published large animal and human studies. A total of nine porcine studies comparing cold storage to normothermic machine perfusion for donation after circulatory death grafts were included for analysis...

OBJECTIVE: To study the correlations and discrepancies between Child-Pugh system and indocyanine green (ICG) clearance test in assessing liver function reserve and explore the possibility of combining two systems to gain an overall liver function assessment. DESIGN: Retrospective analysis of 2832 hepatocellular carcinoma (HCC) patients graded as Child-Pugh A and Child-Pugh B with ICG clearance test being performed was conducted. RESULTS: ICG retention rate at 15 minutes (ICG15) correlates with Child-Pugh score, however, with a large variance...

INTRODUCTION: Gallbladder carcinoma (GBC) is the most common malignancy of the biliary tract and the third most common gastrointestinal tract malignancy. This study examines a large cohort of GBC patients in the United States in an effort to define demographics, clinical, and pathologic features impacting clinical outcomes. METHODS: Demographic and clinical data on 22,343 GBC patients was abstracted from the SEER database (1973-2013). RESULTS: GBC was presented most often among Caucasian (63...

Pseudocysts are a recognised complication following acute or chronic pancreatitis. Usually located in peripancreatic areas, they have also been reported to occur in atypical regions like liver, pelvis, spleen, and mediastinum. Mediastinal pseudocysts are a rare entity and present with myriad of symptoms due to their unique location. They are a clinical challenge to diagnose and manage. In this paper, we describe the clinical and radiological characteristics of mediastinal pseudocysts in 7 of our patients, as well as our experience in managing these patients along with their clinical outcome...

Introduction . Postoperative pancreatic fistula formation remains the major complication after distal pancreatectomy. At our institution, we have recently developed a novel bovine serum albumin-glutaraldehyde sealed hand sutured fish-mouth closure technique of the pancreatic remnant during distal pancreatectomy. The aim of this study was to analyze the impact of this approach with regard to technical feasibility and overall postoperative outcome. Patients and Methods . 32 patients who underwent a bovine serum albumin-glutaraldehyde sealed hand sutured fish-mouth closure of the pancreatic remnant during distal pancreatectomy between 2012 and 2014 at our institution were analyzed for clinically relevant postoperative pancreatic fistula formation (Grades B and C according to ISGPF definition) and overall postoperative morbidity...

Objective . The incidence of pancreatic cancer is estimated to be 48,960 in 2015 in the US and projected to become the second and third leading causes of cancer-related deaths by 2030. The mean costs in 2015 may be assumed to be $79,800 per patient and for each resection $164,100. Attempt is made to evaluate the results over the last 80 years, the number of survivors, and the overall survival percentage. Methods . Altogether 1230 papers have been found which deal with resections and reveal survival information...

Objective . To evaluate if early cholecystectomy (EC) is the most appropriate treatment for acute cholecystitis compared to delayed cholecystectomy (DC). Patients and Methods . A retrospective cohort study of 1043 patients was carried out, with a group of 531 EC cases and a group of 512 DC patients. The following parameters were recorded: (1) postoperative hospital morbidity, (2) hospital mortality, (3) days of hospital stay, (4) readmissions, (5) admission to the Intensive Care Unit (ICU), (6) type of surgery, (7) operating time, and (8) reoperations...

Background . After pancreaticoduodenectomy (PD), pancreatic fistulas (PF) are a frequent complication. Infusions may compromise anastomotic integrity. This retrospective analysis evaluated associations between intraoperative fluid excess and PF. Methods . Data on perioperative parameters including age, sex, laboratory findings, histology, infusions, surgery time, and occurrence of grade B/C PF was collected from all PD with pancreaticojejunostomy (PJ) performed in our department from 12/2011 till 02/2015. The glomerular filtration rate (GFR), infusion rate, and the ratio of both and its association with PF were calculated...

Background. Hepatectomy, an important treatment modality for liver malignancies, has high perioperative morbidity and mortality rates. Safe, comprehensive criteria for selecting patients for hepatectomy are needed. Since June 2011, we have used a cut-off value of ≧ 0.05 for future liver remnant plasma clearance rate of indocyanine green as a criterion for hepatectomy. The aim of this study was to verify the validity of this criterion. Methods. From June 2011 to December 2015, 212 hepatectomies were performed in Tenri Yorozu Hospital...

Background. Bile contamination from the digestive tract is a well-known risk factor for postoperative complications. Despite the literature concerning prevalence of bacterobilia and fungobilia in patients with biliary pathologies, there are no specific recommendations for perioperative antimicrobial coverage for biliary/pancreatic procedures. We evaluated the effect of at least 72 hours of perioperative broad spectrum antibiotic coverage on outcomes of pancreaticoduodenectomy (PD). Materials and Methods. A retrospective review of all patients at Case Medical Center of Case Western Reserve University undergoing PD procedure, from 2006 to 2011, was performed (n = 122)...

Hepatocellular carcinoma (HCC) is one of the most commonly diagnosed cancers worldwide. Majority of patients with HCC are diagnosed in the advanced stages of disease and hence they are only suitable for palliative therapy. TACE (transarterial chemoembolization) is the most commonly used treatment for unresectable HCC. It is however unclear if TACE improves the quality of life (QoL) in patients with HCC. The aim of this review is to evaluate the impact of TACE on QoL of HCC patients.

Background. The reported incidence of noncurative laparotomies for pancreatic cancer using standard imaging (SI) techniques for staging remains high. The objectives of this study are to determine the diagnostic accuracy of diagnostic laparoscopy with ultrasound (DLUS) in assessing resectability of pancreatic tumors. Study Design. We systematically searched the literature for prospective studies investigating the accuracy of DLUS in determining resectability of pancreatic tumors. Results. 104 studies were initially identified and 19 prospective studies (1,573 patients) were included...

Aim. Acute pancreatitis is an inflammatory intra-abdominal disease, which takes a severe form in 15-20% of patients and can result in high mortality especially when complicated by acute renal failure. The aim of this study is to assess the possible reduction in the extent of acute kidney injury after administration of eugenol in an experimental model of acute pancreatitis. Materials and Methods. 106 male Wistar rats weighing 220-350 g were divided into 3 groups: (1) Sham, with sham surgery; (2) Control, with induction of acute pancreatitis, through ligation of the biliopancreatic duct; and (3) Eugenol, with induction of acute pancreatitis and eugenol administration at a dose of 15 mg/kg...

Introduction. Hepatocellular carcinoma (HCC) is a rare pediatric cancer accounting for 0.5% of all pediatric malignancies.
