PURPOSE: We studied the prevalence of the transpancreatic common hepatic artery (tp-CHA) and coexisting variant anatomy. MATERIALS AND METHODS: The study group comprised 788 consecutive liver transplant donor candidates who had undergone thin-section multidetector-row computed tomography (MDCT) studies to investigate vascular anatomy. Multiplanar reformatted (MPR) images obtained from the arterial phase were retrospectively reviewed to assess the presence/absence of the tp-CHA...

Pancreatic allograft thrombosis (PAT) remains the leading cause of non-immunological graft failure. Herein we propose a new CT grading system of PAT to identify risk factors for allograft loss and outline a management algorithm by retrospective review of consecutive pancreatic transplants between 2009-2014. Triple-phase CT scans were graded independently by two radiologists as; Grade 0 - no thrombosis, Grade 1 - peripheral thrombosis, Grade 2 - intermediate non-occlusive thrombosis and Grade 3 - central occlusive thrombosis...

Prophylaxis for graft portal/splenic venous thrombosis following pancreas transplant varies between institutions. Similarly, treatment of venous thrombosis ranges from early re-exploration to conservative management with anticoagulation. We wished to determine the prevalence of graft splenic vein (SV) thrombosis, as well as the clinical significance of non-occlusive thrombus observed on routine imaging. Records of 112 pancreas transplant recipients over a five-year period at a single center were reviewed. Venous thrombosis was defined as absence of flow or presence of thrombus identified in any part of the graft SV on ultrasound...

BACKGROUND: In radical operations for gastric cancer, a balance between the quality of lymph node dissection and safety of surgery must be ensured. During suprapancreatic lymphadenectomy in laparoscopic gastrectomy (LG), an adequate operative field should be safely and effectively established to reduce pancreas-related complications. We present a novel approach that avoids direct compression of the pancreas in LG and describe the surgical outcomes of this method. METHODS: We historically compressed the pancreas during suprapancreatic lymph node dissection in LG to obtain an adequate operative field but have since modified our operative technique...

INTRODUCTION: In the 50 years since the first pancreas transplant performed at the University of Minnesota, the surgical techniques employed have undergone many modifications. Techniques such as retroperitoneal graft placement have further improved the ability to reproduce the physiology of the «native» pancreas. We herein present our experience of a modified technique for pancreatic transplant, with the organ placed into a fully retroperitoneal position with systemic venous and enteric drainage of the graft by duodeno-duodenostomy...

PURPOSE: Bolus-tracked multiphasic contrast computed tomography (CT) is often used in diagnostic radiology to enhance the visibility of pancreas tumors, but is uncommon in radiation therapy pancreas CT simulation, and its impact on gross tumor volume (GTV) delineation is unknown. This study evaluates the lesion conspicuity and consistency of pancreas stereotactic body radiation therapy (SBRT) GTVs contoured in the different contrast phases of triphasic CT simulation scans. METHODS AND MATERIALS: Triphasic, bolus-tracked planning CT simulation scans of 10 consecutive pancreas SBRT patients were acquired, yielding images of the pancreas during the late arterial (LA), portal venous (PV), and either the early arterial or delayed phase...

BACKGROUND: The guidelines for the classification of the resectability of pancreatic cancer established by the National Comprehensive Cancer Network can be difficult to utilize in clinical practice. We evaluated novel criteria proposed by the Japan Pancreas Society. METHODS: We analyzed 382 patients with pancreatic cancer between 2001 and 2015 for survival differences among subgroups classified according to the Japan Pancreas Society classification. Overall survival and disease-free survival were expressed as median values and compared with data based on the National Comprehensive Cancer Network classification, and differences in initial patterns of recurrence were analyzed...

REVIEW
R Vera, L Díez, E Martín Pérez, J C Plaza, A Sanjuanbenito, A Carrato
Surgical resection is the only potentially curative option in the treatment of pancreatic ductal adenocarcinoma. Preoperative radiological imaging allows to rule out the presence of metastases. Three resectability categories are established based on the radiological findings depending on the degree of contact between the tumor and the blood vessels. Histological confirmation of malignancy is only required in cases of borderline or non-resectable tumors, prior to neoadjuvant treatment initiation. Diagnostic laparoscopy is recommended in the presence of large tumors of the body or tail and in borderline tumors to explore the possibility of resection and to apply treatment with curative intent, as well as in those cases with high level of biomarkers to rule out peritoneal involvement...

Hepatobiliopancreatic surgery is challenging becouse of the complexity of resections and reconstructions and variability of vascular anatomy. The arterial vascularization of the liver is susteined by the common hepatic artery (CHA) that originates from the celiac trunk (CT). The CHA bifurcates into the gastroduodenal artery (GDA) and proper hepatic artery (PHA) 0.5-1 cm medial to the common bile duct (CBD), and the PHA bifurcates into a right and a left branch at hepatic hilum. The most frequent variants are the right hepatic artery (RHA) from the superior mesenteric artery (SMA), the left hepatic artery (LHA) from the left gastric artery (LGA) or a combination of these two variants...

INTRODUCTION: Endosonography guided celiac plexus neurolysis is efficacious in the management of severe pain due to advanced pancreatic cancer. Although endoscopic ultrasound (EUS) guided celiac neurolysis (CN) is mostly a safer procedure than the percutaneous posterior approach, severe complications such as paraplegia have been reported. CASE REPORT: We describe a patient with advanced adenocarcinoma of the pancreas and severe pain who developed irreversible paraplegia after EUS guided CN...

BACKGROUND: Organ dysfunction is common after neurologic determination of death (NDD) but before organ collection. Reliable markers for graft success following transplant of these organs would be useful. We sought to determine the relationship between the donor after neurologic determination of death (DNDD) pathophysiology and successful organ donation. METHODS: Donor information was obtained through the local organ procurement organization. Donor demographics and clinical data points for cardiovascular, renal, respiratory, hepatic, hematological and neuroendocrine systems were reviewed 12 h before and 12 h after neurologic determination of death was declared...

INTRODUCTION: We present a 51 year old, African American, female who presented with persistent hypoxemia. She had been taking dapsone for many years for prophylaxis against Pneumocystic Jiroveci with no symptoms but eventually developed methemoglobinemia only after a splenectomy. From our literature review there are no documented cases that have demonstrated this relationship between dapsone, splenic function and methemoglobin and we hope to share our perplexing case and shed light on the interaction...

Schwannomas are neurogenic tumors that arise from the neural sheaths of peripheral nerves. These tumors can be located in any area of the human body; the most common locations are the head, neck, trunk and extremities. Pancreatic schwannomas are very rare. Over the past 40 years, only 67 cases of pancreatic schwannomas have been reported in the English literature. Here we present a case of pancreatic schwannoma in a 62-year-old male. The tumor was revealed by ultrasound and computed tomography in the neck and body of the pancreas...

BACKGROUND/AIMS: Studies of human cadaveric pancreas specimens indicate that pancreas inflammation plays an important role in type 1 diabetes pathogenesis. Due to the inaccessibility of pancreas in living patients, imaging technology to visualize pancreas inflammation is much in need. In this study, we investigated the feasibility of utilizing ultrasound imaging to assess pancreas inflammation longitudinally in living rats during the progression leading to type 1 diabetes onset. METHODS: The virus-inducible BBDR type 1 diabetes rat model was used to systematically investigate pancreas changes that occur prior to and during development of autoimmunity...

BACKGROUND: To support a hypothesis that there is an intrinsic interplay between coronary artery disease (CAD) and type 2 diabetes (T2D), we used RNA-seq to identify unique gene expression signatures of CAD, T2D, and coexisting conditions. METHODS: After transcriptome sequencing, differential expression analysis was performed between each disordered state and normal control group. By comparing gene expression profiles of CAD, T2D, and coexisting conditions, common and specific patterns of each disordered state were displayed...

Pseudoaneurysm of peripancreatic vessel is a rare complication of pancreatitis. The splenic artery is the most commonly affected vessels close to the pancreas. Pseudoaneurysm of right gastroepiploic artery is rare. It can rupture into Gastro Intestinal (GI) tract, retroperitoneum, peritoneal cavity, biliopancreatic duct or pseudocyst. Clinical diagnosis of unruptured pseudoaneurysm is rarely possible because there are no specific signs and symptoms. We hereby report a case of pseudoaneurysm of aberrant right gastroepiploic artery in 30-year-old male which presented with history of epigastric pain and lump with episode of haematemesis and malena...
