Papilla with Separate Bile and Pancreatic Duct Orifices
JOP. J Pancreas (Online) 2013 May 10; 14(3):302-303. MULTIMEDIA ARTICLE – Clinical Imaging Papilla with Separate Bile and Pancreatic Duct Orifices Surinder Singh Rana, Deepak Kumar Bhasin Department of Gastroenterology, Post Graduate Institute of Medical Education and Research (PGIMER). Chandigarh, India A 32-year-old male, a known case of alcohol related Conflict of interest The authors have no potential chronic non calcific pancreatitis, was referred to us for conflicts of interest pancreatic endotherapy for relief of intractable abdominal pain. The cross sectional imaging studies References had revealed an irregularly dilated main pancreatic duct. The examination of the major duodenal papilla 1. Silvis SE, Vennes JA, Dreyer M. Variation in the normal duodenal papilla. Gastrointest Endosc 1983; 29:132-133 [PMID; revealed the presence of two separate orifices at 6852473] endoscopic retrograde cholangiopancreatography (ERCP) (Image). The cranial orifice was located at 11- 12 clock position whereas the caudal orifice was located at 4-5 clock position. The caudal orifice was selectively cannulated and the injection of the contrast revealed presence of an irregularly dilated main pancreatic duct. The cannula and the guide wire introduced through the caudal orifice selectively entered the pancreatic duct and did not come out through the cranial orifice. During ERCP, bile could be seen coming out of the cranial orifice, confirming it to be the orifice of common bile duct. Following selective cannulation of the main pancreatic duct, a 5-Fr stent was placed into the pancreatic duct. Following this, the patient had complete pain relief and is planned for further sessions of pancreatic endotherapy along with pancreatic sphincterotomy. -
SAGES Clinical Spotlight Review: Intraoperative Cholangiography
SAGES Clinical Spotlight Review: Intraoperative cholangiography William W. Hope, MD, Robert Fanelli MD, Danielle S. Walsh MD, Ray Price MD, Dimitrios Stefanidis MD, William S. Richardson MD, and the SAGES Guidelines Committee Preamble The following clinical spotlight review regarding the intraoperative cholangiogram is intended for physicians who manage and treat gallbladder/biliary pathology and perform laparoscopic cholecystectomy. It is meant to critically review the technique of intraoperative cholangiography, alternatives for intraoperative biliary imaging, and the available evidence supporting their safety and efficacy. Based on the level of evidence, recommendations may or may not be given for their use in clinical practice. Disclaimer Guidelines for clinical practice and spotlight reviews are intended to indicate preferable approaches to medical problems as established by experts in the field. These recommendations will be based on existing data or a consensus of expert opinion when little or no data are available. Spotlight reviews are applicable to all physicians who address the clinical problem(s) without regard to specialty training or interests, and are intended to convey recommendations based on a focused topic; within the defined scope of review, they indicate the preferable, but not necessarily the only acceptable approaches due to the complexity of the healthcare environment. Guidelines and recommendations are intended to be flexible. Given the wide range of specifics in any health care problem, the surgeon must always choose the course best suited to the individual patient and the variables in existence at the moment of decision. Guidelines, spotlight reviews, and recommendations are developed under the auspices of the Society of American Gastrointestinal Endoscopic Surgeons and its various committees, and approved by the Board of Governors. -
Fact Sheet - Symptoms of Pancreatic Cancer
Fact Sheet - Symptoms of Pancreatic Cancer Diagnosis Pancreatic cancer is often difficult to diagnose, because the pancreas lies deep in the abdomen, behind the stomach, so tumors are not felt during a physical exam. Pancreatic cancer is often called the “silent” cancer because the tumor can grow for many years before it causes pressure, pain, or other signs of illness. When symptoms do appear, they can vary depending on the size of the tumor and where it is located on the pancreas. For these reasons, the symptoms of pancreatic cancer are seldom recognized until the cancer has progressed to an advanced stage and often spread to other areas of the body. General Symptoms Pain The first symptom of pancreatic cancer is often pain, because the tumors invade nerve clusters. Pain can be felt in the stomach area and/or in the back. The pain is generally worse after eating and when lying down, and is sometimes relieved by bending forward. Pain is more common in cancers of the body and tail of the pancreas. The abdomen may also be generally tender or painful if the liver, pancreas or gall bladder are inflamed or enlarged. It is important to keep in mind that there are many other causes of abdominal and back pain! Jaundice More than half of pancreatic cancer sufferers have jaundice, a yellowing of the skin and whites of the eyes. Jaundice is caused by a build-up bilirubin, a substance which is made in the liver and a component of bile. Bilirubin contains a lot of yellow pigment, and gives bile it’s color. -
Impact of Preoperative Endoscopic Ultrasound in Surgical Oncology
REVIEW Impact of preoperative endoscopic ultrasound in surgical oncology Endoscopic ultrasound (EUS) has a strong impact on the imaging and staging of solid tumors within or in close proximity of the upper GI tract. Technological developments during the last two decades have increased the image quality and allowed very detailed visualization of local tumor spread and lymph node affection. Current indications for EUS of the upper GI tract encompass the differentiation between benign and malignant lesions, the staging of esophageal, gastric and pancreatic cancer, and the procurement of a biopsy specimen through fine-needle aspiration. Various technical innovations during the past two decades have increased the diagnostic quality and have simultaneously strengthened the role of EUS in the clinical setting. This article will give a compressed summary on the current state of EUS and possible further technical developments. 1 KEYWORDS: 3D imaging elastosonography endoscopic ultrasound miniprobes Sascha S Chopra & oncologic surgery Michael Hünerbein† 1Department of General & Transplantation Surgery, Charité Campus Virchow-Clinic, Berlin, Conventional endoscopic ultrasound the so-called ‘miniprobes’ into the biliary system Germany Linear versus radial systems or the pancreatic duct in order to obtain high-res- †Author for correspondence: Department of Surgery & Surgical Endoscopic ultrasound (EUS) with flex- olution radial ultrasound images locally.

Bile Duct Risk Factors A risk factor is anything that affects your chance of getting a disease like cancer. Different cancers have different risk factors. Some risk factors, like smoking, can be changed. Others, like a person’s age or family history, can’t be changed. But having a risk factor, or even many risk factors, does not mean that a person will get 1 ____________________________________________________________________________________American Cancer Society cancer.org | 1.800.227.2345 the disease. And many people who get the disease have few or no known risk factors. Researchers have found some risk factors that make a person more likely to develop bile duct cancer. Certain diseases of the liver or bile ducts People who have chronic (long-standing) inflammation of the bile ducts have an increased risk of developing bile duct cancer. Certain conditions of the liver or bile ducts can cause this, these include: ● Primary sclerosing cholangitis (PSC), a condition in which inflammation of the bile ducts (cholangitis) leads to the formation of scar tissue (sclerosis). People with PSC have an increased risk of bile duct cancer. -

Under the auspices of the World Association of Veterinary Anatomists (W.A.V.A.), the International Committee on Veterinary Anatomical Nomenclature (I.C.V.A.N.) appointed in Giessen, 1965, a Subcommittee on Histology and Embryology which started a working relation with the Subcommittee on Histology of the former International Anatomical Nomenclature Committee. In Mexico City, 1971, this Subcommittee presented a document entitled Nomina Histologica Veterinaria: A Working Draft as a basis for the continued work of the newly-appointed Subcommittee on Histological Nomenclature. This resulted in the editing of the Nomina Histologica Veterinaria: A Working Draft II (Toulouse, 1974), followed by preparations for publication of a Nomina Histologica Veterinaria. -
