“…[1][2][3][4][5][6][7][8][9][10][11][12] MR cholangiopancreatography is noninvasive and capable of providing an anatomic map of the biliary tree and pancreatic duct without the use of ionizing radiation or contrast medium. 2 MR cholangiopancreatography is based on the principle that slow moving fluids are hyperintense on heavily T2weighted images, so bile and pancreatic fluids in the pancreaticobiliary system will be hyperintense resulting in increased duct to background contrast, particularly when postprocessed as maximum intensity projections (MIP). 3,4 MR cholangiopancreatography has been compared with endoscopic retrograde cholangiopancreatography, which is the gold standard for evaluating pancreaticobiliary disorders in people.…”

“…MR cholangiopancreatography was as accurate as endoscopic cholangiopancreatography, but without the associated risks, such as acute pancreatitis, cholangitis, perforation, and hemorrhage. [1][2][3]5,9,13 The advantages to MR cholangiopancreatography include its noninvasive nature, decreased operator dependence, compared with endoscopic cholangiopancreatography, better demonstration of ducts proximal to an obstruction/stenosis, and, when combined with conventional T1 and T2 imaging, anatomic imaging of extraductal disease within the liver and pancreas. 4,14 Cholangitis/cholangiohepatitis is second only to hepatic lipidosis as the most common liver disease in cats and is either lymphocytic or neutrophilic.…”

Magnetic resonance (MR) cholangiopancreatography is useful in humans to diagnose biliary and pancreatic diseases. Some of these protocols incorporate the use of secretin, which stimulates the exocrine pancreas to release bicarbonate with secondary dilation of the pancreatic duct. We compared the utility and quality of multiple hepatic-pancreaticobiliary MR imaging sequences before and after secretin stimulation of the pancreatic duct in five healthy cats. Multiple MR sequences were evaluated, including fast Spoiled Gradient Recalled in- and out-of-phase, Single Shot Fast Spin Echo (SSFSE), T2 Fast Spin Echo, MR cholangiopancreatography (pre- and postsecretin administration), and Fast Acquisition with Multiphase Efgre (FAME) (postsecretin and before and after gadolinium administration). The MR cholangiopancreatography protocol with secretin stimulation was feasible and yielded high-contrast maps of the biliary ductal anatomy but the pancreactic duct was seen inconsistently. The FAME series most consistently provided visualization of biliary and postsecretin pancreatic ductal anatomy, combined with very good depiction of the liver and pancreas. The remaining sequences each had satisfactory utility and diagnostic quality, with the exception of the SSFSE sequences. Secretin improved the conspicuity of the pancreatic duct.

“…Leakage was spontaneously closed after ERCP without any additional intervention in nine patients, all with the low-output leakage. The period for the spontaneous closure after ERCP was average seven (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) days. Spontaneous closure was achieved in 14 patients who underwent sphincterotomy during ERCP and in 56 patients who underwent plastic stent placement additionally to sphincterotomy.…”

BACKGROUND: Iatrogenic biliary tract injury (BTI) is a rare complication but has high risks of morbidity and mortality when it is not early noticed. Although the treatment varies depending on the size of injury and the time until the injury is noticed, endoscopic and percutaneous interventions are usually sufficient. However, it should be remembered that these interventions may cause major complications in the following years, such as biliary stricture, recurrent episodes of cholangitis and even cirrhosis. In this paper, we aimed to present our approach to BTI following cholecystectomy and our treatment management in the light of the literature. METHODS:The medical records of 105 patients who were treated for BTI between January 2015 and July 2019 were evaluated retrospectively. The majority of the patients consisted of the patients who underwent cholecystectomy at an external medical center and were referred to our clinic due to biliary leakage (BL). Patients were grouped according to Strasberg classification determined by the place of leakage. RESULTS:Among 105 patients included in this study, 55 were male, and 50 were female. Mean age was 55.2 ±16.26 years (range, 21-93 years). According to Strasberg classification, type A, B, C, D and E injuries were detected in 57, 1, 3, 29 and 15 patients, respectively. Eighty-five patients were successfully treated with endoscopic and percutaneous interventions, while 20 patients underwent surgery. CONCLUSION:In all patients with suspected BTI, a detailed screening and appropriate treatment provide a significant decline in morbidity and mortality. Therefore, early diagnosis is very important for both early and late outcomes.

Intraductal papillary mucinous neoplasms (IPMNs) represent a group of cystic pancreatic neoplasms with large range of clinical behaviours, ranging from low-grade dysplasia or borderline lesions to invasive carcinomas. They can be grouped into lesions originating from the main pancreatic duct, main duct IPMNs (MD-IPMNs), and lesions which arise from secondary branches of parenchyma, denominated branch-duct IPMNs (BD-IPMNs). Management of these cystic lesions is essentially based on clinical and radiological features. The latter have been very well described in the last fifteen years, with many studies published in literature showing the main radiological features of IPMNs. Currently, the goal of imaging modalities is to identify “high-risk stigmata” or “worrisome feature” in the evaluation of pancreatic cysts. Marked dilatation of the main duct (>1 cm), large size (3–5 cm), and intramural nodules have been associated with increased risk of degeneration. BD-IPMNs could be observed as microcystic or macrocystic in appearance, with or without communication with main duct. Their imaging features are frequently overlapped with cystic neoplasms. The risk of progression for secondary IPMNs is lower, and subsequently an imaging based follow-up is very often proposed for these lesions.

Magnetic resonance cholangiopancreatography and contrast-enhanced magnetic resonance cholangiopancreatography versus endoscopic ultrasonography in the diagnosis of extrahepatic biliary pathology

Abstract: MRCP and EUS do not show significant statistical differences in diagnostic accuracy. MRCP is an accurate, noninvasive modality in the study of extrahepatic biliary pathology. EUS is especially reliable in patients with extrahepatic biliary obstruction caused by endoluminal sludge.
