OBJECTIVES: To determine the value of a raw data-based metal artifact reduction (SEMAR) algorithm for image quality improvement in abdominal CT for patients with small metal implants. METHODS: Fifty-eight patients with small metal implants (3-15 mm in size) who underwent treatment for hepatocellular carcinoma were imaged with CT. CT data were reconstructed by filtered back projection with and without SEMAR algorithm in axial and coronal planes. To evaluate metal artefact reduction, mean CT number (HU and SD) and artefact index (AI) values within the liver were calculated...

BACKGROUND: Imaging has a critical impact on surgical decision making and three-dimensional (3D) digital models of patient pathology can now be made commercially. We developed a 3D digital model of a cancer of the head of the pancreas by integrating actual CT data with 3D modeling process. After this process, the virtual pancreatic model was also produced using a high-quality 3D printer. PATIENTS AND METHODS: A 56-year-old female with pancreatic head adenocarcinoma presented with biliary obstruction and jaundice...

BACKGROUND: The complex anatomy of the pancreaticobiliary duct was crucial in management of pancreatic and biliary tract disease. MATERIALS AND METHODS: Fresh specimens of pancreas, common bile duct (CBD), and duodenum were obtained en bloc from autopsies of 160 patients. RESULTS: Ninety-three male and 67 female patients were included. The length of the pancreas ranged from 9.8-20 cm (mean, 16.20 +/- 1.70 cm). The intrapancreatic portion of the CBD showed patterns of three types: most common (85...

The vertebrate pancreas is comprised of a highly branched tubular epithelium, which is intimately associated with an extensive and specialized vasculature. While we know a great deal about basic vascular anatomy of the adult pancreas, as well as islet capillaries, surprisingly little is known about the ontogeny of its blood vessels. Here, we analyze development of the pancreatic vasculature in the mouse embryo. We show that pancreatic epithelial branches intercalate with the fine capillary plexus of the surrounding pancreatic mesenchyme...

Considering the physiological importance of the pancreas as an endocrine and exocrine organ, this study described the characteristics of the gross and microscopic morphology of this organ using 16 Myrmecophaga tridactyla individuals. The pancreas was located in the left antimere of the body, was pale in colour and exhibited an elongated shape with a central body and lobulated surface. It was positioned in the abdomen, following the curvatura ventriculi major of the stomach, and was attached to the initial portion of the duodenum...

BACKGROUND: Knowledge about anatomic variations in intrahepatic biliary ducts (IHBD) is relevant for performing biliary drainage and for avoiding bile duct injury during cholecystectomy and liver resections. Low insertion of cystic duct (LICD) is a common anatomic variant. Pancreas divisum is the commonest congenital anomaly of pancreas; it has been causally linked with recurrent acute pancreatitis (RAP). METHODS: Magnetic resonance cholangiopancreaticography (MRCP) images of 500 consecutive patients were reviewed for anatomic variants of IHBD, cystic duct, and pancreatic duct...

BACKGROUND: After an acute attack of pancreatitis, walled-off pancreatic fluid collections (PFC) occur in approximately 10 % of cases. Drainage of the cavity is recommended when specific indications are met. Endoscopic drainage has been adopted as the main intervention for symptomatic walled-off PFC. Altered gastric anatomy in these patients poses an interesting challenge. We present the first case of a patient with sleeve gastrectomy who underwent successful endoscopic transduodenal necrosectomy (TDN)...

In the seventeenth century, opportunities to discover chyle came about through the revival of vivisection. Gaspare Aselli discovered chyle vessels in a living well-fed dog in 1622. He introduced the term 'lacteals' or milky veins. According to Aselli, the lacteals passed through a mesenteric gland which he called 'pancreas'. The 1627 edition of Aselli's booklet was the start of a 'lymphomania', which led to the dissection and vivisection of hundreds of animals, with the University of Leiden being the clear leader in this field...

As basic knowledge for evaluation of pancreatic toxicity, anatomical structures were compared among experimental animal species, including rats, dogs, monkeys, and minipigs. In terms of gross anatomy, the pancreases of dogs, monkeys, and minipigs are compact and similar to that of humans. The rat pancreas is relatively compact at the splenic segment, but the duodenal segment is dispersed within the mesentery. In terms of histology, the islet of each animal is characterized by a topographic distribution pattern of α- versus β-cells...

AIM: Organ procurement errors account for almost 20% of discarded pancreatic allografts. For this reason, the anatomical significance of the dorsal pancreatic artery (DPA) was reviewed. METHODS: A strategy on dealing with an often overlooked DPA is evaluated. RESULTS: The DPA provides together with the splenic artery the main blood supply to the pancreatic tail. Three different arterial variations have been described. In the rare instances when the DPA arises from the common hepatic artery or the celiac trunk, instead of the splenic origin, the DPA can easily be overlooked by surgeons not familiar with this artery...

OBJECTIVES: An increasing number of children are being diagnosed with pancreatitis and other pancreatic abnormalities. Dissemination of the information regarding existing imaging techniques and endoscopic modalities to diagnose and manage pancreatic disorders in children is sorely needed. METHODS: We conducted a review of the medical literature on the use of the following imaging and procedural modalities in pediatric pancreatology: transabdominal ultrasonography (TUS), computed tomography (CT), magnetic resonance imaging (MRI)- magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasonography (EUS), endoscopic retrograde cholangiopancreatography (ERCP)...

Aberrant hepatic arterial anatomy poses a challenge for the surgeon during Whipple procedure. Intraoperative injury to the aberrant vasculature results in hemorrhagic or ischemic complications involving the liver and biliary tree. We report a case of replaced right hepatic artery arising from the superior mesenteric artery in a patient with periampullary carcinoma of the pancreas, undergoing pancreaticoduodenectomy. The aberrant artery was found to be coursing through the pancreatic parenchyma. This is a rare vascular anomaly...

BACKGROUND: The conventional radical resection of proximal gastric cancer is even more risky when performed laparoscopically, though this technique is widely used in gastrointestinal surgery and is accepted as the superior method. This paper explores the feasibility of laparoscopic spleen-preserving hilar lymph node dissection using a retro-pancreatic approach for the treatment of proximal gastric cancer. METHODS: Two cadavers were dissected for examination of and the pre-pancreatic and retro-pancreatic spaces...

BACKGROUND: Low-dose ionizing radiation from medical imaging has been indirectly linked with subsequent cancer and increased costs. Computed tomography (CT) is the gold standard for defining pancreatic anatomy and complications. Our primary goal was to identify the temporal trends associated with diagnostic imaging for inpatients with pancreatic diseases.

Culinary terms have been used to describe anatomy (bean-shaped kidneys), pathology (strawberry gall bladder), clinical signs (café-au-lait spots), radiological images (sausage-shaped pancreas), etc. While Indian cuisine is popular all over the world, no Indian dish finds mention in medical terminology. In intra-abdominal adhesions, sometimes, the intestinal loops are so densely adherent that it is difficult to make out proximal from distal and it is impossible to separate them without injuring the bowel resulting in spill of contents-resection is the only option (Fig...

The complex anatomy of the retroperitoneum is reflected in the spectrum of neoplastic and nonneoplastic conditions that can occur in the retroperitoneum and appear as soft-tissue masses. The presence of fat within a retroperitoneal lesion is helpful in refining the differential diagnosis. Fat is easily recognized because of its characteristic imaging appearance. It typically is hyperechoic at ultrasonography and demonstrates low attenuation at computed tomography (-10 to -100 HU). Magnetic resonance imaging is a more ideal imaging modality because it has better soft-tissue image contrast and higher sensitivity for depicting (a) microscopic fat by using chemical shift imaging and (b) macroscopic fat by using fat-suppression techniques...

Deficient function in the anion channel cystic fibrosis (CF) transmembrane conductance regulator is the fundamental cause for CF. This is a monogenic condition that causes lesions in several organs including the respiratory tract, pancreas, liver, intestines, and reproductive tract. Lung disease is most notable, given it is the leading cause of morbidity and mortality in people with CF. Shortly after the identification of CF transmembrane conductance regulator, CF mouse models were developed that did not show spontaneous lung disease as seen in humans, and this spurred development of additional CF animal models...

On May 16, 2015 at the invitation of the American Gastroenterological Association Institute Council E.P.D. presented a state-of-the-art lecture at Digestive Disease Week 2015. The aims were to discuss a selection of landmark papers in chronic pancreatitis (CP) that influence modern management and to conclude by suggesting some future directions. This is based on that presentation. We will specifically review the following: duct anatomy and pancreas divisum, description of chronic relapsing pancreatitis and its differentiation from recurrent acute pancreatitis and established CP (ECP), natural histories and gene discoveries of alcoholic, idiopathic and hereditary pancreatitis, development of pancreatic cancer in CP, exocrine pancreatic insufficiency and calculation of dose and delivery of enzymes, endoscopic ultrasonography, and autoimmune pancreatitis...

Successful surgical resection offers the only chance for cure in patients with pancreatic cancer. However, pancreatic resection is feasible in less than 20% of the patients. In this review, the current state of surgical management of pancreatic cancer is discussed. The definition of resectability based on cross-sectional imaging and the technical aspects of surgery, including vascular resection and/or reconstruction, management of aberrant vascular anatomy and extent of lymphadenectomy, are appraised. Furthermore, common pancreatic resection-specific postoperative complications and their management are reviewed...
