ERCP and MRCP--when and why.
2002
Since the introduction of endoscopic retrograde cholangiopancreatography (ERCP) in the 1970s, gastroenterologists have a wide spectrum of diagnostic and therapeutic options in the biliopancreatic ductal system at their disposal. With its arrival in the 1990s, magnetic resonance cholangiopancreatography (MRCP) developed as a potent diagnostic tool in biliopancreatic pathology. Currently, MRCP is widely replacing diagnostic ERCP and thereby avoiding complications related to endoscopic technique.We summarize evidence-based data and demonstrate indications and differential indications for MRCP and ERCP in pancreatic disease. Complications related to the procedures and possible medical preventio…
The hippocampus and remote autobiographical memory.
2005
In Newsdesk (August, 2005),1 new evidence for the neuroanatomy of remote memory was reported. On the basis of the findings of the US team lead by Larry Squire,2 remote autobiographical memory was suggested to be independent of the medial temporal lobe but dependent on the neocortex. By contrast with previous hypotheses, this new proposal predicts that after damage to the medial temporal lobe only recent autobiographical memories should be impaired in neurological patients, whereas loss of both recent and old autobiographical memories implies additional damage in the neocortex. However, there is evidence not included in the Newsdesk article, that is problematic for this new prediction. Two p…
Choledochocele imaged with magnetic resonance cholangiography.
2000
Choledochal cysts are rare developmental malformations of the biliary tree. Percutaneous and endoscopic ultrasound, as well as endoscopic retrograde cholangiopancreatography, are recommended diagnostic tools. Magnetic resonance cholangiography may also contribute to the workup and treatment plan of patients with choledochal cysts. We report a 25-yr-old white woman with episodic nausea and moderate epigastric dyscomfort. Magnetic resonance cholangiography showed a rather spherical, cyst-like, fluid-filled structure in continuity with the prepapillary segment of the common bile duct, thus making a choledochocele (type III choledochal cyst) likely. The patient was treated by endoscopic sphinct…
Biliopancreatic Endoscopy in Altered Anatomy
2021
Background and Objectives: Anatomical post-surgical alterations of the upper gastrointestinal (GI) tract have always been challenging for performing diagnostic and therapeutic endoscopy, especially when biliopancreatic diseases are involved. Esophagectomy, gastrectomy with various reconstructions and pancreaticoduodenectomy are among the most common surgeries causing upper GI tract alterations. Technological improvements and new methods have increased the endoscopic success rate in these patients, and the literature has been rapidly increasing over the past few years. The aim of this systematic review is to identify evidence on the available biliopancreatic endoscopic techniques performed i…
Magnetic Resonance Imaging in Gastroenterology: Time to Say Good-bye to All That Endoscopy?
2000
Magnetic resonance imaging (MRI) has been described as the most important development in medical diagnosis since the discovery of the roentgen ray more than 100 years ago. The effectiveness of MRI has been extended to make it applicable in a wide variety of gastrointestinal disorders. The attention of gastroenterologists is currently focusing on pancreaticobiliary and bowel diseases. Magnetic resonance cholangiopancreatography (MRCP) has become a competitive alternative to diagnostic endoscopic retrograde cholangiopancreatography in a variety of hepatobiliary and pancreatic diseases. Magnetic resonance enteroscopy has the potential to become the preferable method for evaluating the entire s…
Fascioliasis: A worldwide parasitic disease of importance in travel medicine
2014
Fascioliasis is a foodborne zoonotic disease caused by the two parasite species Fasciola hepatica and Fasciola gigantica. This trematodiasis has never been claimed special relevance for travellers and migrants. However, the situation has drastically changed in the last two decades, in a way that fascioliasis should today be included in the list of diseases to be enhanced in Travel Medicine. Different kind of travellers have been involved in human infection reports: business travellers, tourists, migrants, expatriated workers, military personnel, religious missionaries, and refugees. Europe is the continent where more imported cases have been reported in many countries. More cases would have…
Human bile microbiota: A retrospective study focusing on age and gender
2021
Aims: The emerging biliary colonization of microorganisms in patients with biliary diseases may be devastating. Recent evidence suggests that age and gender may influence changes in the microbial composition of gut microbiota. To study the relationship between these parameters on bile microbiota, we retrospectively reviewed positive bile cultures following an endoscopic retrograde cholangiopancreatography (ERCP) in a QA-certified academic surgical unit of a single institution. Methods: 449 positive bile cultures from 172 Italian patients with diseases of the biliopancreatic system hospitalized from 2006 through 2017 were investigated for aerobic, anaerobic, and fungal organisms. The patient…
Endoscopic cytology in biliary strictures. Personal experience
2008
The differential diagnosis between malignant and benign biliary strictures is the cornerstone of the management of jaundiced patients. The aim of our study is to define the role of cytology of the bile withdrawn during endoscopic retrograde cholangiopancreatography (ERCP), to reach a diagnosis of the nature of biliary stricture.This retrospective study was conducted on 67 consecutive patients affected of ingravescent obstructive jaundice who underwent ERCP+/-PTE (percutaneous transhepatic endoscopic)+bile withdrawn+stenting. We founded hilar stricture in 21 patients (31.3%), middle third the common duct stricture in 17 (25.3%), and lower third stricture in 28 patients (41.4%). In one patien…
Diagnosis of sclerosing cholangitis in children: blinded, comparative study of magnetic resonance versus endoscopic cholangiography.
2013
Summary Background Magnetic resonance cholangiography (MRC) has been validated as comparable to endoscopic retrograde cholangiography (ERC) for the diagnosis of sclerosing cholangitis (SC) in adult patients. In children, MRC is widely used based mainly on non-comparative studies. Patients and methods ERCs and MRCs of seven children (median age 9, range: 7–20 years) with SC and 17 controls (median age 6, range: 2 months–20 years) with other chronic liver diseases were reviewed in a blinded, random and independent way. All patients underwent both examinations within a 6-months slot. All ERCs and 17 MRCs were performed under general anesthesia. One radiologist evaluated both ERCs and MRCs and …
