Pitfalls of MRCP in the diagnosis of pancreaticobiliary maljunction. (1/217)

CONTEXT: Magnetic resonance cholangiopancreatography (MRCP) is useful for examining the pancreatic duct system in patients with acute pancreatitis instead of using endoscopic retrograde cholangiopancreatography (ERCP), as ERCP-induced pancreatitis represents a serious problem. However, we present here a case of idiopathic acute pancreatitis in which MRCP suggested pancreaticobiliary maljunction, but ERCP indicated normal pancreaticobiliary union. CASE REPORT: A 22-year-old male was urgently admitted complaining of upper abdominal and back pain. He had no history of alcohol or drug intake. Serum amylase levels were elevated to 880 U/mL (reference value: less than 158 U/mL). Abdominal ultrasound demonstrated only a slight swelling of the pancreas, but no abnormal findings for the bile duct or gallbladder. Symptoms and hyperamylasemia improved with supportive therapy. Coronal heavily T2-weighted single-shot rapid acquisition with relaxation enhancement MRCP indicated a markedly long common channel, and pancreaticobiliary maljunction without biliary dilatation was diagnosed. Under the diagnosis of idiopathic acute pancreatitis associated with pancreaticobiliary maljunction without biliary dilatation, prophylactic laparoscopic cholecystectomy was planned. However, ERCP demonstrated a narrow main pancreatic duct and a normal common bile duct without the formation of a common channel. In a supine position, after withdrawal of the scope, the narrow main pancreatic duct at the head of the pancreas overlapped the lower common bile duct, giving the appearance of a long common channel as indicated by MRCP. CONCLUSIONS: In MRCP of cases with a narrow main pancreatic duct, there is a possibility for false-positive indications of pancreaticobiliary maljunction. MRCP with secretin stimulation or ERCP should be performed in such cases.  (+info)

Unilocular extrahepatic biliary cystadenoma mimicking choledochal cyst: a case report. (2/217)

We report here on a case of extrahepatic biliary cystadenoma arising from the common hepatic duct. A 42-year-old woman was evaluated by us to find the cause of her jaundice. Ultrasonography and CT showed a cystic dilatation of the common hepatic duct and also marked dilatation of the intrahepatic duct. Direct cholangiography demonstrated a large filling defect between the left hepatic duct and the common hepatic duct; dilatation of the intrahepatic duct was also demonstrated. Following excision of the cystic mass, it was pathologically confirmed as a unilocular biliary mucinous cystadenoma arising from the common hepatic duct.  (+info)

A case of acute pancreatitis possibly associated with combined salicylate and simvastatin treatment. (3/217)

CONTEXT: Drug-induced acute pancreatitis is a rather rare clinical entity. From time to time, several cases have been reported in which statins or salicylates have been associated with the development of acute pancreatitis. There is only one report which implies the involvement of both drugs in pancreatic inflammation. CASE REPORT: A 58-year-old Caucasian male with a history of coronary heart disease and hypercholesterolemia, under treatment with acetyl-salicylate for 6 years and simvastatin for 2 months, presented to the Emergency Department of our hospital with epigastric pain and vomiting of 24-hour duration. The clinical and laboratory investigation led to the diagnosis of acute pancreatitis. Conservative and rich-in-fluid treatment resulted in clinical and laboratory amelioration, and the patient was discharged on day 15, after full restoration of his health. In our patient, all possible common causes of acute pancreatitis were excluded. CONCLUSION: Conclusion It is a rational assumption to connect this case to the co-administration of simvastatin and acetyl-salicylate. However, the pathophysiological mechanism behind the onset of acute pancreatitis due to a statin, or, even more, due to its combination with salicylate, remains vague.  (+info)

Preoperative evaluation of pancreaticobiliary tumor using MR multi-imaging techniques. (4/217)

AIM: To evaluate the clinical value of MR multi-imaging techniques in diagnosing and preoperative assessment of pancreaticobiliary tumor. METHODS: MR multi-imaging techniques, including MR cross-sectional imaging, MR cholangiopancreatography (MRCP) and 3D dynamic contrast-enhanced MR angiography (3D DCE MRA), were performed to make prospective diagnosis and preoperative evaluation in 28 patients with suspected pancreaticobiliary tumors. There were 17 cases of pancreatic adenocarcinoma, 8 cases of biliary system carcinoma and 3 cases of non-neoplastic lesions. RESULTS: Using MR multi-imaging techniques, the accuracy in diagnosing the patients with pancreaticobiliary tumors was 89.3% (25/28). The accuracy in detecting the range of tumor invasion was 80.3% (57/71). The sensitivity, specificity, accuracy, positive and negative predictive value of MR multi-imaging techniques in preoperative assessment of the resectability of pancreaticobiliary tumor were 83.3%, 89.5%, 88.0%, 71.4%, and 94.4%, respectively. There was well diagnostic consistency between MR multi-imaging techniques and CT (kappa = 0.64, P<0.01). The fusion image could be made from MRCP and 3D DCE MRA images. CONCLUSION: MR multi-imaging techniques can integrate the advantages of various MR images. The non-invasive "all-in-one" MR imaging protocol is the efficient method in diagnosing, staging and preoperative assessment of pancreaticobiliary tumor.  (+info)

Magnetic resonace appearance of gall bladder ascariasis. (5/217)

Ascariasis is a common disease in many developing countries and is a common cause of biliary and pancreatic diseases in endemic areas. Numerous studies have been published on biliary tract ascariasis. All these have documented ultrasonography as the primary imaging modality for biliary tract ascariasis. Magnetic Resonance Cholangiopancreatography (MRCP) has been the latest entrant for the study of bilary tract. MRCP findings of biliary tract ascariasis have been scarcely documented. MRCP is a unique non-invasive investigation for demonstrating ascariasis in gall bladder and bilary tract clearly. We present MR appearances of gall bladder and biliary tract in a proven case of biliary ascariasis.  (+info)

Dynamic MR cholangiography after fatty meal loading: cystic contractility and dynamic evaluation of biliary stasis. (6/217)

PURPOSE: Dynamic MR cholangiography was conducted on patients with cholelithiasis or choledocholithiasis who had consumed a fatty test meal (Molyork) and the cystic contractility and dynamics of biliary stasis was evaluated. SUBJECTS AND METHOD: The subjects were 25 with intracystic cholelithiasis, 10 with choledocholithiasis and 10 normal controls. For an imaging sequence, the rapid acquisition with relaxation enhancement (RARE) method was employed and imaging was conducted for 40 min (every 30 s following Molyork administration) without breath-holding. The gallbladder contraction ratio was computed and the contractile ratio for the common bile duct was calculated. To determine the bile flow to the duodenum, the high-intensity signal, indicating the flow from the lower common bile duct, and perfusion of the duodenum were observed in dynamic mode on the monitor with the naked eye and interpreted as positive bile flow. The frequency of this flow was visually monitored. RESULTS: The gallbladder contractile ratio was significantly reduced in patients with cholelithiasis or choledocholithiasis compared with the controls. In a comparison with the normal controls, no sequential changes were noted in the mean contractile ratio of the common bile duct of the patients with cholelithiasis or choledocholithiasis. The mean frequency of bile flow observed for each 40 min period was 13+/-2.4, 6+/-2.2, and 4+/-1.3 times for the controls, those with intracystic cholelithiasis, and those with choledocholithiasis, respectively. Compared with the controls, the latter two patient groups showed evident reductions in the frequency of bile flow to the duodenum (p<0.001). CONCLUSION: Dynamic MRC combined with Molyork loading makes it possible to compute cystic contractile ratios and perform a dynamic examination of bile flow under non-invasive, near-physiological conditions.  (+info)

Adenomyomatosis with marked subserosal fibrosis and lipomatosis of the gallbladder: mural stratification demonstrated with MR. (7/217)

The authors reported a case of fundal-type adenomyomatosis in which mural stratification corresponding to histopathological findings was clearly demonstrated with MR imaging. Single-shot fast spin echo images for MR cholangiopancreatography clearly visualized Rokitansky-Aschoff sinuses (RAS), which are a diagnostic clue for this disease. However, mural stratification comprising RAS with muscular proliferation, massive fibrosis and subserosal fat deposition was more precisely demonstrated in T(2)-weighted images obtained with fast spin echo.  (+info)

Complications of endoscopic retrograde cholangiography in the post-MRCP era: a tertiary center experience. (8/217)

AIM: To evaluate our experience in endoscopic retrograde cholangio-pancreatography (ERCP) in terms of fulfilling the ASGE guidelines in indications, positive findings, and complications in the post-magnetic resonance cholangiopancreatography (MRCP) era. METHODS: Between November 2001 and February 2003, consecutive ERCP cases were prospectively evaluated with regard to the indications, findings, cannulation techniques, devices used during the procedure, sedation given, duration of procedure, and complications. These data were entered in a database for subsequent processing and analysis. RESULTS: Of 336 cases, 21.4% were diagnostic and 78.6% therapeutic ERCP. The indications for ERCP fulfilled the ASGE guidelines in 323 cases (96.1%). Suspected bile duct stone was the most frequent indication (26.8%), and this was followed by cholangitis (24.4%), dilated common bile duct (14.9%), and cholestatic jaundice (13.4%). Cannulation success rate was 94%. Biliary sphincterotomy was performed in 175 (52.1%) patients. Repeated ERCP was performed on 31.5% of the patients. Overall, the complication rate was 9.8% with 0.3% being procedure-related mortality. The complications were pancreatitis (5.4%), bleeding (0.8%), cholangitis (2.4%) and others (1.5%). No significant difference was observed between the complication rate and the type of ERCP performed. CONCLUSION: Our study showed that post-ERCP complication rate was comparable with the other large prospective studies and there was no difference in the complication between the diagnostic and therapeutic ERCP.  (+info)

Results:. It was observed that the presence of dilatation of the biliary tract or choledocholithiasis in the ultrasonography was four and eight times increased risk of perioperative cholangiography for positive choledocholithiasis, respectively. For each unit increased in serum alkaline phosphatase was 0.3% increased the risk of perioperative cholangiography for positive choledocholithiasis. In the presence of dilatation of the bile ducts in the ultrasonography was four times greater risk of positive magnetic resonance cholangiopancreatography for choledocholithiasis. In the presence of pancreatitis these patients had five times higher risk of positive magnetic resonance cholangiopancreatography for choledocholithiasis. On the positive magnetic resonance cholangiopancreatography presence to choledocholithiasis was 104 times greater of positive perioperative cholangiography for choledocholithiasis. ...
Magnetic resonance cholangiopancreatography (MRCP) is a medical imaging technique that uses magnetic resonance imaging to visualize the biliary and pancreatic ducts in a non-invasive manner. This procedure can be used to determine if gallstones are lodged in any of the ducts surrounding the gallbladder. It was introduced in 1991. MRCP makes use of heavily T2-weighted MRI pulse sequences. These sequences show high signal in static or slow moving fluids within the gallbladder, biliary ducts and pancreatic duct, with low signal of surrounding tissue. In the diagnosis of pancreatic disorders, MRCP is a much less invasive investigation when compared to endoscopic retrograde cholangiopancreatography (ERCP). Although both techniques can image the ductal system in detail, MRCP also allows imaging of the surrounding parenchyma. In a study from 2008, 269 patients undergoing both ERCP and MRCP showed comparable results between the two techniques. Prasad, SR; D. Sahani; S. Saini (November 2001). Clinical ...

We report a case of cholecysto-colonic fistula in a female patient, due to bile duct lithiasis. Cholelithiasis is the most common cause of fistula (in more than 90% of the cases) [1]. Cholelithiasis could cause either repeated episodes of acute cholecystitis/cholangitis or asymptomatic chronic calculous cholecystitis [1]. The chronological events that lead to the fistula include gallbladder inflammation, adhesions between intestines and gallbladder, mechanical erosion by gallstones and gangrenous changes of both the gallbladder and the adjacent colon wall.. Enterobiliary fistulae most commonly result from calculus cholecystitis, but can also occur occasionally following carcinoma of the gallbladder where the necrotic tumour perforates into the adjacent duodenum or colon, or both [2]. Due to its proximity, the duodenum is the most common site of intestines involved.. Biliary ileus is defined as a mechanical intestinal obstruction due to a gallstone lodging in the intestinal lumen. The usual means ...
This book aims to provide the basic technology and recent advances in biliopancreatic endoscopy. The method of Endoscopic retrograde cholangiopancreatography (ERCP) is popularly applied to enlarge the papillary orifice for removal of biliary and pancreatic stones, to relieve obstruction of distal bile duct or pancreatic duct by nasobiliary / nasopancreatic drainage or stenting, and to remove the premalignant tumor of papilla in recent four decades. The diagnostic role of ERCP is already replaced by the noninvasive images such as abdominal sonography, computed tomography, magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasonography (EUS ...
Chronic pancreatitis is the progressive and permanent destruction of the pancreas resulting in exocrine and endocrine insufficiency and, often, chronic disabling pain. The etiology is multifactorial. Alcoholism plays a significant role in adults, whereas genetic and structural defects predominate in children. The average age at diagnosis is 35 to 55 years. Morbidity and mortality are secondary to chronic pain and complications (e.g., diabetes, pancreatic cancer). Contrast-enhanced computed tomography is the radiographic test of choice for diagnosis, with ductal calcifications being pathognomonic. Newer modalities, such as endoscopic ultrasonography and magnetic resonance cholangiopancreatography, provide diagnostic results similar to those of endoscopic retrograde cholangiopancreatography. Management begins with lifestyle modifications (e.g., cessation of alcohol and tobacco use) and dietary changes followed by analgesics and pancreatic enzyme supplementation. Before proceeding with endoscopic or

My 15 years old son has moderate pain in his upper stomach for the last 2 weeks and has been diagnosed with a single gallstone. Ultrasonography (USG) showed the size of the stone as 14 mm but magnetic resonance cholangiopancreatography (MRCP) showed it 4 mm. The stone is at the neck of gallbladder (GB). The doctor has advised for |b|surgical removal of gallbladder|/b|. Later on, he has been put on Ursocol 300 mg for 3 months. What are the chances of gallstone dissolving by the drug given? Even if the stone will dissolve, would the GB return to normal functioning? What are the chances of recurrence of gallstones? Is surgery advisable?
A 44-year-old man, post-cholecystectomy for gallstones, was diagnosed with acute myeloid leukemia. He was treated with chemotherapy and achieved the first complete response (CR). The relapse in the bone marrow was confirmed twice and he achieved the third CR at the age of 47 years. After nine courses of consolidation chemotherapy to prepare for transplantation, he underwent allogeneic hematopoietic stem cells from bone marrow of a one-mismatch female donor at the age of 50 years. Acute and chronic graft-versus-host disease (GVHD) developed post-transplant, which was successfully treated by increased immunosuppression.. At the age of 59 years, the patient was noted to have elevated liver and biliary enzymes. Computed tomography (CT) showed a nodule in the lower bile duct, which was slowly enhanced by dynamic CT (Figure 1A). Magnetic resonance cholangiopancreatography (MRCP) revealed post-chole-cystectomy state, dilatation of intra- and extra-hepatic bile duct (Figure 1B) and a space-occupying ...
As reported by Vasen et al in the Journal of Clinical Oncology, surveillance for pancreatic ductal adenocarcinoma in high-risk individuals appears to be of benefit in individuals at risk due to CDKN2A mutation, with the advantage being less clear among individuals at risk due to familial clustering of pancreatic cancer.. Study Details. The study was a long-term prospective follow-up from three European expert centers. A total of 411 asymptomatic individuals, including 178 CDKN2A mutation carriers, 214 individuals with familial pancreatic cancer, and 19 BRCA1/2 or PALB2 mutation carriers, participated in a surveillance program consisting of annual magnetic resonance imaging (MRI), magnetic resonance cholangiopancreatography, or endoscopic ultrasound (EUS).. Individuals had a mean age of 56 years at the start of the program, and mean follow-up was 53 months (range = 0-169 months). In total, 866 MRIs and 106 EUSs were performed.. Surveillance Outcome.

The underlying concept is to image fluid within the ducts while suppressing signal from non-fluid structures [8]. The main aim of this classic MRCP sequence is to demonstrate ductal fluid as hyperintense while filling defects, such as those caused by stones, are displayed as hypointense [12]. Traditionally, a set of radially oriented thick slab MRCP images were obtained and may still be the case in many centres [44, 47]. It has been somewhat successful and so it is understandable that centres continue to use this approach. This may be of benefit when anatomical structures are difficult to identify on axial images (perhaps due to prior surgery or congenital anomalies) or because of an advanced stage of pathology which results in severe distortion of the relevant anatomical structures. However, the authors believe that this approach, if used for every case, may falsely lead to an oversimplification of the MRCP procedure. It may even be considered as a novice approach since it is not targeted ...

Today was my follow up appointment for the MRCP I had back in January. Good news is the cyst either shrunk or was miscalculated from the endoscopic ultrasound. It is only about 1.5 cm up from 1.2 cm the time before (the endo ultrasound showed it at 2.2 cm). Unfortunately, I need to have another MRCP early April so we can be sure. And then in the same month, I need to meet with a pancreatic surgeon to go over my options - if I need surgery to remove it, if we can just follow it, or if we can virtually ignore it. Hopefully we can just monitor it for now ...

Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems. Through the endoscope, the physician can see the inside of the stomach and duodenum, and inject a contrast medium into the ducts in the biliary tree and pancreas so they can be seen on radiographs. ERCP is used primarily to diagnose and treat conditions of the bile ducts and main pancreatic duct, including gallstones, inflammatory strictures (scars), leaks (from trauma and surgery), and cancer. ERCP can be performed for diagnostic and therapeutic reasons, although the development of safer and relatively non-invasive investigations such as magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasound has meant that ERCP is now rarely performed without therapeutic intent. The following represent indications for ERCP, particularly if or when less invasive options are not adequate or ...
MRC is emerging as the latest imaging technology to evaluate the biliary tree. This noninvasive method is used to visualize these structures without using a contrast agent. Because the magnetic resonance images can be directly acquired in any plane, 3-dimensional representation of biliary tract anatomy and pathology can be accurately obtained. Patients receive no radiation exposure and unlike other imaging modalities, such as ultrasonography, ERCP, or percutaneous transhepatic cholangiography, MRC does not rely on operator skill. The limitations of MRC include imaging artifact caused by metallic surgical clips and air in the biliary tree. Additionally, MRC does depend on technology that requires a multicoil device for better spatial resolution, which is currently not widely available (1). Should MRC be used in the routine diagnosis of biliary tract disease, and where does it fit in the diagnostic work-up? Although Soto and colleagues should be commended for their efforts, it is difficult to ...

Malignant hilar tumours are usually unresectable at the time of diagnosis.6 7 Although resection offers the only chance of cure, the five year survival rate after potentially curative resection for hilar cholangiocarcinoma has been reported to be from 0 to 22%,2 16 and the resectability rate from 20 to 30%6 16; there is no indication for surgery in patients with hilar metastases. Hence palliative non-surgical treatment of obstructive jaundice is often the main treatment for most patients at the time of diagnosis, as radical excision of hilar tumours is precluded by the patients general condition, tumour extension into both lobes of the liver, portal vein, or hepatic artery tumour encasement, or distant metastasis.. When communication persists between the right and left hepatic ducts (Bismuths type I), the endoscopic insertion of a single stent is admittedly the best way to ensure drainage, although some type I stricture patients may be candidates for surgical resection or bypass. When the ...
A 46-year-old woman without a significant history presented our emergency room with acute epigastric pain. Abdominal computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) demonstrated a well-defined 2.1-cm cystic lesion at the neck of the pancreas, without peripancreatic infiltration, that was connected to the pancreatic duct (Fig. 1A). Serum laboratory findings were as follows: amylase 142 U/L, lipase 149 U/L, carcinoembryonic antigen (CEA) 0.94 ng/mL, and cancer antigen 19-9 10.22 U/mL. Endoscopic ultrasound (EUS) demonstrated a distinct anechoic lesion connected to the main pancreatic duct (Fig. 1B). EUS-guided fine needle aspiration (EUS-FNA) retrieved clear cystic fluid with low viscosity. Histopathologic examination of the cystic fluid demonstrated ductal epithelial cells without a malignant component. Analysis of the cystic fluid showed CEA 10.45 ng/mL and amylase 126 IU/L, suggesting low potential for malignancy. Thus, the pancreatic cystic lesion was initially ...

This study aimed to evaluate the radiologists ability to identify excreted gadoxetate disodium within the gallbladder on CT scan. Thirty three healthy adults underwent imaging of the liver during work-up for potential liver donation. Three patients had undergone prior cholecystectomy and therefore were excluded. Imaging consisted of gadoxetate disodium-enhanced magnetic resonance cholangiography (MRC) and multiphase contrast-enhanced CT scan of the abdomen and pelvis. Two fellowship-trained abdominal imaging radiologists, who were blinded to the MRC images and the contrast agent used during MRC, independently reviewed the CT scans of the 30 patients that were included. The scans were evaluated for the presence or absence of abnormal hyperdensity within the gallbladder. Three patients did not receive intravenous gadoxetate disodium, 4 patients had their MRC after the CT scan, and 1 patient had the CT scans 5 days following the MRC. Twenty two patients had the CT scan within 24 h following the gadoxetate

Hello everyone. I would like to present all what I have learned by moderating the MRCP 1 forum at RxPG. For months, it had been a roller coaster ride, right upto to the exam and continues to date too. Every now and then I see someone coming up with a post as to be asking how to prepare for this exam. I have a few very basic and concrete suggestions which should form the base of your studying pyramid and you can then gradually build your knowledge upon it. All what I say here has been my experience with support from other doctors opinions and the RxPG MRCP 1 forum s members comments.... ...

BACKGROUND There are few published data concerning the economic impact of antibiotic prophylaxis prior to endoscopic retrograde cholangiopancreatography in the setting of biliary obstruction. AIM To perform decision analysis to determine the costs of prophylaxis in patients undergoing endoscopic retrograde cholangiopancreatography for obstructive jaundice. METHODS A decision analysis model was constructed. The probability of biliary sepsis, death and endoscopic retrograde cholangiopancreatography complications was obtained from the medical literature and from a retrospective analysis of our own experience. Costs were obtained from Medicare reimbursement at our institution. The strategies evaluated were endoscopic retrograde cholangiopancreatography with and without single-dose antibiotic prophylaxis. We compared the total costs, number of episodes of cholangitis and deaths associated with each strategy. RESULTS Based on published data and the results of our retrospective analysis, the strategy of
Hepatic clonorchiasis is one of the most prevalent food-borne parasitic diseases worldwide. Clonorchis sinensis, the pathogen, is the major parasitic trigger contributing to cholangitis, cholelithiasis, and even cholangiocarcinoma. Unfortunately, unspecific clinical manifestations of patients with hepatic clonorchiasis tend to mislead clinicians to neglect or misdiagnose them, following ignorance of appropriate therapy. Our case report may shed light on definite diagnosis of clonorchiasis with concomitant cholelithiasis, methodology for surgical drainage of the parasites, and postoperative anthelmintic therapy. Two patients with habit of eating infected raw or undercooked freshwater fish were hospitalized due to right upper quadrant pain and jaundice. Magnetic resonance cholangiopancreatography (MRCP)/computed tomography (CT) detection indicated cholangiolithiasis and cholangiolithiasis with concurrent cholecystolithiasis, respectively. Fecal examinations were both negative for adult worms or eggs of
Project:. This study will compare glyceryl nitrate (GN) treatment to non-active treatment for the prevention of post-ERCP acute pancreatitis, which is an inflammation of the pancreas that can occur after a procedure known as ERCP.. Background:. ERCP (endoscopic retrograde cholangiopancreaticography) is an examination of the pancreas by which it is possible to perform therapeutic measures such as stone removal from the common bile duct and visualisation of the pancreas. Inflammation of the pancreas after the ERCP procedure (called: post-ERCP pancreatitis) is the most feared and common complication of the ERCP. It occurs in 1-40% of patients, with rates of 5% or more being more typical. Currently, the background of post-ERCP pancreatitis is poorly known.. Attempts at preventing post-ERCP pancreatitis have been carried out through a change to low-risk techniques, by avoiding high-risk patients, and by use of pharmacological prophylaxis.. Glyceryl Nitrate:. Glyceryl nitrate is a well-known medicine ...
Endoscopic retrograde cholangiopancreatography, or ERCP, is a procedure to diagnose and treat problems in the liver, gallbladder, bile ducts, and pancreas. It combines X-ray and the use of an endoscope-a long, flexible, lighted tube.
The incidence of biliary tract pathology is growing with an age-related trend, and progresses as the population ages. Endoscopic Retrograde Cholangiopancreatography (ERCP) represents the gold standard for treatment in these cases, but evidence about its safety in the elderly is still debated. We retrospectively analyzed the clinical records of all patients aged ≥65 undergoing ERCP between July 2013 and July 2015. Of 387 ERCP cases, 363 (~ 94%) were completed entirely. The mean age of the study population (n = 363) was 79.9 years old (range 70-95), with 190 subjects aged 70-79 and 173 older than 80. We recorded demographics, Charlson Comorbidity index (CCI), American Society of Anesthesiologists (ASA) physical status classification score, indication for the use of the ERCP procedure, and clinical outcomes. Then, we tested all variables to identify the potential risk factors for complications associated with the procedure. The older group (those ≥80 years old) showed significantly more patients with
