Multicentric Italian survey on daily practice for autoimmune pancreatitis: Clinical data, diagnosis, treatment, and evolution toward pancreatic insuf…

2020

BACKGROUND: Autoimmune pancreatitis (AIP) is a rare, and relatively new, form of chronic pancreatitis. The management of AIP can vary considerably among different centres in daily clinical practice. OBJECTIVES: The aim of this study is to present a picture of epidemiological, clinical characteristics, outcomes, and the real-life practice in terms of management in several academic and non-academic centres in Italy. METHODS: Data on the clinical presentation, diagnostic work-up, treatments, frequency of relapses, and long-term outcomes were retrospectively collected in a cohort of AIP patients diagnosed at 14 centres in Italy. RESULTS: One hundred and six patients were classified as type 1 AI…

Endoscopic papillary large balloon dilation in patients with large biliary stones and periampullary diverticula: Results of a multicentric series.

2018

Abstract Introduction Stone extraction represents the most frequent indication for endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic papillary large balloon dilation (EPLBD) is a recent introduced approach consisting of an endoscopic papillary large balloon dilation following limited endoscopic sphyncterotomy (ES), which has been proven to be safe and effective for extraction of large common bile duct (CBD) stones. Peri-ampullary diverticula (PAD) are described in 10–20% of patients undergoing ERCP. Aim of our study is to evaluate efficacy and safety of EPLBD for the extraction of large biliary stones in patients with PAD. Methods The prospectively collected endoscopy databa…

Permanent stenting in “unextractable” common bile duct stones in high risk patients. A prospective randomized study comparing two different stents

2007

BACKGROUND: Endoscopic sphincterotomy (ES) and stone extraction is the treatment of choice for bile duct stones. Therefore, if ES and conventional stone extraction fail, further treatment is mandatory. Insertion of a biliary endoprosthesis is an effective option. MATERIALS AND METHODS: We treated 30 high-risk patients (17 women and 13 men, mean age 82 years) affected by difficult common bile duct stones. The patients were randomly assigned preoperatively using closed envelopes (blind randomization) into two groups to receive insertion of polyethylene or hydrophilic hydromer-coated polyurethane stent, respectively. Follow-up was achieved by contacting referring physicians and patient's relat…

Value of magnetic-resonance cholangio-pancreatography (MRCP) after unsuccessful endoscopic-retrograde cholangio-pancreatography (ERCP).

1997

Background and Study Aims: The present study tries to evaluate the success rate of MRCP when two attempts by experts to perform ERCP in a center failed. Patients and Methods: From March 1996 to December 1996 thirteen patients fulfilled the inclusion criteria. The MR cholangiopancreatograms were acquired using commercially available software in a clinical MR scanner (Magnetom Expert 1T-Scanner, Siemens, Erlangen, Germany). MRCP utilized heavily T2-weighted turbo-spin echo sequences with fat supression (HASTE). Maximum intensity projection (MIP) of the pancreatic duct and biliary tree was then carried out. Additionally, T1-weighted sequences were obtained using the breath-hold technique. Resu…

Endoscopic treatment of the "sump syndrome" after choledochoduodenostomy: a new technique using an amplatzer septal occluder.

2006

A 58-year-old male patient had been suffering for 35 years from recurrent cholangitis, biliary sludge and infection-induced stone formation after open cholecystectomy because of empyema of the gallbladder and severe acute and delayed postoperative complications. The pathophysiological origin of this chronic "sump syndrome" was a choledochoduodenostomy which had been performed prophylactically at the time of the initial operation. The patient agreed to an experimental treatment option with use of an Amplatzer atrial-septal defect (ASD) occluder for closure of the symptomatic choledochoduodenal fistula. The double-disc occluder was introduced through a 9 French diameter and 90 cm long sheath …

ERCP and MRCP in the Differentiation of Pancreatic Tumors

2004

The introduction of endoscopic retrograde cholangiopancreatography (ERCP) in the early 1970s provided gastroenterologists with a number of diagnostic as well as therapeutic possibilities for examining biliopancreatic systems. In the meantime, magnetic resonance cholangiopancreatography presents a non-invasive alternative to diagnostic ECRP providing the advantage of a lower rate of possible complications. This article addresses the two methods presently available for differentiating pancreatic tumors. The objective of this article is to describe the advantages and disadvantages as well as the possibilities inherent in both methods.

Prospective, randomized, single-center trial comparing 3 different 10F plastic stents in malignant mid and distal bile duct strictures.

2003

Abstract Background: The aim of this study was to determine whether patency rates differ with respect to the material, design, and surface texture of 3 different plastic stents. Methods: A total of 120 patients (median age 70.5 years; interquartile range 62-78 years) with malignant mid or distal bile duct strictures, seen between March 1996 and May 1999, were prospectively randomized to receive a 10F polyurethane stent, a Teflon Tannenbaum stent, or a hydrophilic hydromer-coated polyurethane stent. The primary study outcome measure was the interval between stent insertion and the first episode of clogging (or the presence of jaundice at death without stent exchange). All 3 types of stent we…

Redox signaling in acute pancreatitis

2015

Acute pancreatitis is an inflammatory process of the pancreatic gland that eventually may lead to a severe systemic inflammatory response. A key event in pancreatic damage is the intracellular activation of NF-κB and zymogens, involving also calcium, cathepsins, pH disorders, autophagy, and cell death, particularly necrosis. This review focuses on the new role of redox signaling in acute pancreatitis. Oxidative stress and redox status are involved in the onset of acute pancreatitis and also in the development of the systemic inflammatory response, being glutathione depletion, xanthine oxidase activation, and thiol oxidation in proteins critical features of the disease in the pancreas. On th…

Intraductal aspiration: a promising new tissue-sampling technique for the diagnosis of suspected malignant biliary strictures

2012

Brushing is the most commonly used technique for biliary sampling at ERCP, despite its limited sensitivity. To evaluate intraductal aspiration (IDA) as a new combined endoscopic technique for cytodiagnosis, its cellular adequacy, diagnostic accuracy for cancer detection, feasibility, and safety. Prospective, observational study. Single tertiary referral center. IDA cellular adequacy, diagnostic accuracy for cancer detection, feasibility, and safety. From April 2009 to September 2010, 42 consecutive patients with suspected malignant biliary stricture underwent ERCP, with tissue sampling obtained with IDA. IDA included performance of standard brushing in all patients. After standard brushing,…

Chronic Total Coronary Artery Occlusion Recanalisation with Percutaneous Coronary Intervention — Single Centre 10-Year Experience

2018

Abstract Coronary artery chronic total occlusions (CTO) are common — approximately one-third of patients with significant coronary artery disease on angiography have at least 1 CTO. Invasive treatment of these lesions still remain a major challenge for interventional cardiology due to their complexity. Historically, success rates have improved to about 60–70% by using only the traditional antegrade approach. The results have dramatically improved during the last decade after more widespread application of new retrograde techniques. The aim of our study was to review and analyse single hospital experience in CTO invasive treatment and to evaluate the long-term results. A total of 519 patient…
