Jeffrey J Yu, Michael Morell, John G Lee, David K Imagawa
We report a case a 70-year-old female presenting with abdominal pain who has a cystic duct coursing medial to the common bile duct before anastomosing just proximal to the ampulla. Low medial insertion of the cystic duct is a rare anatomic variant that is easily misidentified on imaging studies and may complicate surgical and percutaneous intervention. It can be identified by pre-operative imaging modalities such as magnetic resonance cholangiopancreatography.

Endoscopic retrograde cholangiopancreatography (ERCP) is a key endoscopy skill used to diagnose and treat pancreatobiliary diseases. However, its diagnostic use is decreasing in favor of other less invasive methods such as magnetic resonance cholangiopancreatography and endoscopic ultrasound. Alternatively, its use has become more important in the therapeutic area. ERCP trainees must know the anatomy and physiology of the pancreatobiliary system, several key basic skills, and complications of a successful procedure...

The movement related cortical potential (MRCP), a slow cortical potential from the scalp electroencephalogram (EEG), has been used in real-time brain-computer-interface (BCI) systems designed for neurorehabilitation. Detecting MPCPs in real time with high accuracy and low latency is essential in these applications. In this study, we propose a new MRCP detection method based on constrained independent component analysis (cICA). The method was tested for MRCP detection during executed and imagined ankle dorsiflexion of 24 healthy participants, and compared with four commonly used spatial filters for MRCP detection in an offline experiment...

pancreatitis appears to exist in the presence of such calculi upon radiology. Having said that, pancreatic ductal stone due to biliary causes (origin), in face of acute pancreatitis, is rare. To the best of our knowledge this was the first case of its kind presented to our hospital in recent past. A 25-year-old female presented to the emergency department of our hospital with an acute episode of pancreatitis. Computerized tomography (CT) scan, endoscopic retrograde cholangiopancreatography (ERCP) & magnetic resonance cholangiopancreatography (MRCP) concluded acute pancreatitis (AP) with dilated main pancreatic duct left side branches and intra ductal calculi...

We describe a 48-year-old man with cholecystolithiasis whose preoperative magnetic resonance cholangiopancreatography (MRCP) scan showed that the right accessory hepatic duct branching from the cystic duct dominated an anterior segment of the right hepatic lobe. We observed the right accessory hepatic duct using intraoperative cholangiography, and we were able to perform laparoscopic cholecystectomy without injuring it. He had no complication after discharge, and a drip-infusion cholangiography-computed tomography (DIC-CT) scan demonstrated that the right accessory hepatic duct was intact, and it dominated an anterior segment of the right hepatic lobe...

Aim: Angiotensin-converting enzyme inhibitors (ACEIs) are commonly used to treat hypertension. Although generally well tolerated, the adverse effects of ACEIs include hypotension, cough, acute kidney injury and hyperkalemia. Rare reports of ACEI-induced hepatotoxicity have been described, most notably a cholestatic pattern of injury related to captopril. A 67-year-old male presented to the emergency department with a three-week history of jaundice, pruritis and weakness. Eight weeks before, he began taking ramipril and clopidogrel...

PURPOSE OF REVIEW: Critical review of the indications for total pancreatectomy and highlight limitations in current diagnostic criteria for chronic pancreatitis. RECENT FINDINGS: The diagnosis of noncalcific chronic pancreatitis remains controversial because of an overreliance on nonspecific imaging and laboratories findings. Endoscopic ultrasound, s-magnetic resonance cholangiopancreatography, and/or endoscopic pancreatic function testing are often used to diagnose noncalcific chronic pancreatitis despite the fact that there is no gold standard for this condition...

BACKGROUND Pancreatic-pleural fistula (PPF) is an uncommon complication of pancreatitis. Pleural effusions secondary to PPF are caused by fistulization of pancreatic secretions to the thorax derived from the rupture or leakage of a pseudocyst. CASE REPORT We describe the case of a 44-year-old male with recurrent right-sided pleural effusions and alcoholic pancreatitis who presented with epigastric pain and shortness of breath. Pleural fluid analysis revealed an amylase of 7002 U/lt. MRCP showed segmental narrowing and stricture of the proximal main pancreatic duct and an area of walled-off necrosis...

We report a case of a 70-year-old man with acute acalculous cholecystitis caused by Giardia lamblia. Contrast-enhanced computed tomography (CT) showed distention of the gallbladder due to a pericholecystic abscess without gallstones. Magnetic resonance cholangiopancreatography and drip infusion cholecystocholangiography-CT demonstrated a stricture of the hilar bile duct and cystic duct obstruction. We conducted transpapillary bile duct brush cytology and a biopsy of the hilar bile duct stricture; numerous active trophozoites of Giardia lamblia were observed without malignant findings...

Staged hepatectomy, particularly associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a recently developed advanced surgery for resecting liver tumors. However, large wound surfaces, incomplete drainage and high rates of mortality are vital limitations of ALPPS. The present case study describes a patient with liver cancer who underwent ALPPS surgery combined with negative pressure wound therapy. A 46-year-old male patient was hospitalized due to right upper abdominal pain. Computed tomography and magnetic resonance cholangiopancreatography scan results indicated gallbladder cancer, accompanied by multiple liver metastases...

BACKGROUND: Aging has been associated with increasing common bile duct (CBD) diameter and reported as independently predictive of the likelihood of choledocolithiasis. These associations are controversial with uncertain diagnostic utility in patients presenting with symptomatic disease. The current study examined the relationship between age, CBD size, and the diagnostic probability of choledocolithiasis. METHODS: Symptomatic patients undergoing evaluation for suspected choledocolithiasis from January 2008 to February 2011 were reviewed...

Benign biliary diseases include a large spectrum of congenital and acquired disorders, which have different prognosis and require different treatment management. The diagnosis may be challenging since some benign disorders may mimic malignancy. Imaging has an important role in the diagnostic process, for treatment decision and planning and in patient follow up. Magnetic resonance (MR) with magnetic resonance cholangiopancreatography (MRCP) sequences is the imaging modality of choice for biliary diseases and has demonstrated high diagnostic accuracy...

A 63-year male was admitted with abdominal pain, fever and jaundice. The contrast-enhanced computed tomography, magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiography showed a mass in the hepatic hilar region with dilation of the intrahepatic bile duct. The left branch of portal vein was also compressed by the mass. The patient was diagnosed as intrahepatic bile duct carcinoma and underwent the left hemihepatectomy together with right hepatic duct jejunum anastomosis (Roux-en-Y)combined with hepatoduodenal ligament lymphadenectomy...

We propose electrocorticographic temporal alteration mapping (ETAM) for motor cortex mapping by utilizing movement-related cortical potentials (MRCPs) within the low-frequency band [0.05-3] Hz. This MRCP waveform-based temporal domain approach was compared with the state-of-the-art electrocorticographic frequency alteration mapping (EFAM), which is based on frequency spectrum dynamics. Five patients (two epilepsy cases and three tumor cases) were enrolled in the study. Each patient underwent intraoperative direct electrocortical stimulation (DECS) procedure for motor cortex localization...

BACKGROUND: Symptomatic pancreaticojejunal anastomotic stricture (PJS) is a rare complication following pancreaticoduodenectomy. The incidence, presentation and management of this condition are infrequently reported in the literature. Revision surgery is thought to be an effective treatment. Recent literature shows some success from endoscopic management. METHODS: The patients treated for symptomatic PJS from January 2005 to June 2014 were identified. Their clinical presentation and management was retrospectively reviewed...

INTRODUCTION: A single gallbladder with a double cystic duct is a very rare finding. In addition, few cases with this rare condition are preoperatively diagnosed. However, the preoperative confirmation or suspicion of this rare condition could facilitate safe laparoscopic cholecystectomy, which is a minimally invasive therapeutic modality for gallbladder disease. We herein present a case of gallstone disease in a patient with a double cystic duct who was preoperatively diagnosed and successfully treated with laparoscopic cholecystectomy...

An 18-year-old man presented with spontaneous severe epigastric pain, progressing and radiating to back since 3 days. It was associated with epigastric tenderness, bilious vomiting and jaundice. He had been intermittently experiencing these symptoms for the last 1 year. No known comorbid. Ultrasound showed a poorly visualised heterogeneous focus at porta hepatis; considering poor visualisation, this might represent an enlarged calcified lymph node or cystic duct calculus causing extrinsic compression or a large sludge ball within the common bile duct (CBD), leading to dilatation of common hepatic duct and intrahepatic biliary system...
