Despite progress in laparoscopic surgery and increasing surgical experience, the incidence of bile duct injury during laparoscopic cholecystectomy fails to fall below 0.3%-0.6% and it is still higher than those recorded in the era of open cholecystectomy. Bile duct injuries belong to the most serious complications of abdominal surgery in general and often end up with liver transplantation as the only hope for cure. We present a case of a 78-year-old jaundiced male patient who sustained common hepatic duct injury during laparoscopic cholecystectomy eight months earlier...

Immunoglobulin G4-related sclerosing cholangitis (IgG4-SC) is often associated with type 1 autoimmune pancreatitis, and the frequency of isolated IgG4-SC seems to be quite low, making the diagnosis of isolated IgG4-SC challenging. A 63-year-old male was admitted to our hospital for frequent fever. Abdominal magnetic resonance cholangiopancreatography showed diffuse narrowing of the common bile duct and post-stenotic dilatation of the right posterior bile duct. Laboratory tests showed abnormalities in the levels of hepatobiliary enzymes and serum IgG4 levels...

Brain-computer interfaces have been a novel approach to translate human intentions into movement commands in robotic systems. This paper describes an electroencephalogram-based brain-controlled lower-limb exoskeleton for gait training, as a proof of concept towards rehabilitation with human-in-the-loop. Instead of using conventional single electroencephalography correlates, e.g., evoked P300 or spontaneous motor imagery, we propose a novel framework integrated two asynchronous signal modalities, i.e., sensorimotor rhythms (SMRs) and movement-related cortical potentials (MRCPs)...

Situs inversus totalis is the mirror image of situs solitus, the normal position of abdominal and thoracic viscera. Many associated intraabdominal anomalies have been described with this condition. However, association of choledochal cyst with situs inversus has never been reported. Diagnosis and surgical procedures for abdominal pathology in patients with situs inversus totalis are technically more complicated and pose unique challenges because of left-right transposition of the visceral organs. The choledochal cyst is usually diagnosed in the neonatal period or during childhood...

Low-frequency electroencephalographic (EEG) activity provides relevant information for decoding movement commands in healthy subjects and paralyzed patients. Brainmachine interfaces (BMI) exploiting these signals have been developed to provide closed-loop feedback and induce neuroplasticity. Several offline and online studies have already demonstrated that discriminable information related to movement can be decoded from low-frequency EEG activity. However, there is still not a well-established procedure to guarantee that this activity is optimally filtered from the background noise...

Although BCI technology has vastly improved in the last few years, very little research has been done into how different types of cues may affect the resulting signal. We have conducted preliminary work to examine the effects of using auditory versus visual cues on MRCP signal detection. While our sample size was small (n=5), the data for auditory and visual cues were not statistically different for young, healthy participants, suggesting that they are comparable for the parameters analyzed. Our results indicated that audio and visual cues likely produce similar MRCP signals, which is useful information for designing non-invasive BCIs...

The movement related cortical potential (MRCP) is a well-known neural signature of human's self-paced movement intention, which can be exploited by future neuroprosthesis. Most existing studies have explored the amplitude representation for the movement intention. In this paper we investigate the Hilbert transformed MRCP, which implicitly includes phase information complementarily to amplitude information, for the detection of self-paced upper-limb movement intention. On the datasets in which 5 healthy subjects executed a self-initiated upper limb center-out reaching task in three sessions, we have evaluated the detection model with Hilbert transformed MRCP as features and the state-of-art one with the original MRCP amplitude as features...

AIM: Primary sclerosing cholangitis (PSC), with no curative intervention, can progress to end-stage liver disease. Mizoribine, a purine anti-metabolic, has never been used for the management of PSC. To evaluate the role of mizoribine with azathioprine we performed a preliminary clinical study in children with PSC. METHODS: Children with PSC and autoimmune features were simultaneously treated with mizoribine and azathioprine. Ursodeoxycholic acid or mesalazine were not regulated...

Primary sclerosing cholangitis (PSC) remains a rare but potentially devastating chronic, cholestatic liver disease. PSC causes obstruction of intra- and/or extra-hepatic bile ducts by inflammation and fibrosis, leading to biliary obstruction, cirrhosis and portal hypertension with all associated sequelae. The most dreaded consequence of PSC is cholangiocarcinoma, occurring in 10-20% of patients with PSC, and with population-based estimates of a 398-fold increased risk of cholangiocarcinoma in patients with PSC compared to the general population...

A 36-year-old woman was diagnosed with compensated cirrhosis of liver secondary to Budd-Chiari syndrome (BCS) and had undergone stenting of a thrombosed left hepatic vein. Eight months later, she presented with jaundice and right upper quadrant pain. CT revealed multiple focal lesions in the liver, which on biopsy proved to be hepatic hemangioendothelioma (HHE). Her liver disease and ascites progressively increased. Four months later, magnetic resonance cholangiopancreatography showed an advanced stage of HHE with infiltration of the common bile duct and vascular invasion with a blocked stent, with metastasis to the spleen and dorsolumbar vertebrae...

Given the low disease prevalence of both exocrine and endocrine cancers in the general population, screening is not recommended. However, in as many as 25% of cases there is a precursor lesion or an identifiable genetic predisposition. For these patients at increased risk, screening with imaging is recommended. Multidetector computed tomography, MR imaging or magnetic resonance cholangiopancreatography, and endoscopic ultrasound examination can be used as screening modalities. Recent advances in dual energy CT and total body MR imaging have increased the suitability of these noninvasive modalities as first-line imaging screening options...

A 59-year-old woman was admitted for acute pancreatitis. Abdominal computed tomography and magnetic resonance imaging revealed a swollen pancreatic parenchyma with dilatation of the main pancreatic duct (MPD) of the pancreas tail, which was separated from the normal pancreas body side by a locally atrophic part of the pancreas. Magnetic resonance cholangiopancreatography showed MPD stricture in the pancreas tail with dilatation of the upstream MPD. Endoscopic ultrasonography revealed that the MPD stricture of the pancreas tail was surrounded by a blurred and hypoechoic area...

A 73-year-old male with a complaint of abdominal discomfort was examined by abdominal ultrasonography and found to have a hypoechoic mass in the upper abdomen. On abdominal computed tomography (CT), there was a 5-cm, hypervascular mass between the stomach and aorta. Magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography (MRCP) showed a homogeneous mass with hypointensity on T1-weighted images, accompanied by stenosis of the main pancreatic duct of the pancreatic head. On endoscopic ultrasonography, the mass was depicted as a round homogeneous, hypervascular mass attached to the pancreatic head...

Cholangiocarcinoma (CCA) is the most common malignancy in primary sclerosing cholangitis (PSC). Approximately half of CCA are diagnosed within two years of initial diagnosis and often have a poor prognosis because of advanced tumor stage at the time of diagnosis. Thus, rigorous initial imaging evaluation for detecting CCA is important. CCA in PSC usually manifests as intrahepatic mass-forming or perihilar periductal-infiltrating type. Imaging diagnosis is often challenging due to pre-existing biliary strictures and heterogeneous liver...

Detection of single-trial movement intentions from EEG is paramount for brain-computer interfacing in neurorehabilitation. These movement intentions contain task-related information and if this is decoded, the neurorehabilitation could potentially be optimized. The aim of this study was to classify single-trial movement intentions associated with two levels of force and speed and three different grasp types using EEG rhythms and components of the movement-related cortical potential (MRCP) as features. The feature importance was used to estimate encoding of discriminative information...

BACKGROUND AND OBJECTIVES: The use of routine versus selective intra-operative cholangiogram (IOC) for laparoscopic cholecystectomy (LC) remains an area of debate. In this study, we investigated the routine use of IOC in a single center, to determine whether it confers a reduced risk of common bile duct (CBD) injury and improved patient outcomes. We also identified several preoperative predictive factors for CBD stone detection on IOC to investigate the feasibility of a predictive model...
