AIM/BACKGROUND: Evaluations of abdominal ultrasonography (US) findings of primary and secondary tumor-forming hepatic malignant lymphoma (HML) have not been adequately reported. In this study, we elucidated US and contrast-enhanced US (CEUS) findings in patients with HML. MATERIALS/METHODS: From January 2006 to March 2017, 25 patients with HML were enrolled (primary 7, secondary 18), each of whom was diagnosed pathologically. They were divided into 2 groups based on tumor diameter (cutoff, 30 mm)...

A 51-year-old man with no relevant medical history presents to the emergency department complaining of a recent worsening of few months upper abdominal pain with back radiation and postprandial fullness, without B symptoms. Laboratory analysis showed hyperamylasaemia, elevated lactate dehydrogenase and inflammatory parameters. Abdominal ultrasonography revealed a heterogeneous solid mass in the spleen/splenic hilum with pancreatic parenchyma continuity and no biliary tract dilation or gallstones. A mild acalculous acute pancreatitis diagnosis was made...

BACKGROUNDS/AIMS: The challenging dilemma of Mirizzi syndrome for operating surgeons arises from the difficulty to diagnose it preoperatively, and approximately 50% of cases are diagnosed intraoperatively. In this study, we analysed the effectiveness of diagnostic modalities and treatment options in our series of Mirizzi syndrome. METHODS: Patients had a preoperative or intraoperative diagnosis of Mirizzi syndrome, and were classified into three groups: Group 1: Incidental finding of Mirizzi syndrome intraoperatively (n=34)...

The gallbladder and bile ducts are usually assessed initially with conventional gray-scale ultrasound (US). Contrast enhanced US (CEUS) is used when a diagnosis cannot be reached with conventional US. CEUS is easy to learn and perform. US contrast agents can be safely administered in patients with renal function impairment. In this pictorial essay the physics, examination technique and indications of CEUS for examining the gallbladder and bile ducts are reviewed. Gallbladder indications include elucidating normal variants, differentiating sludge from neoplastic lesions, benign and malignant pathology, infection, wall rupture and hemobilia...

Laparoscopic cholecystectomy (LC) is the gold standard technique for the treatment of gallbladder disease. However, in some cases, conversion to open surgery is still necessary. Identification of patients with high risk of conversion is of great importance to prepare the surgical scenario and to anticipate the convalescence. The objective of this study is to identify the factors that may predict a conversion to an open procedure. A total of 1386 LC were performed in Dr. Manuel Gea González General Hospital, from January 2009 to May 2013...

Desmoid type fibromatosis (DTF) is a rare, locally invasive, non-metastasizing soft tissue tumor. We report an interesting case of DTF involving the pancreatic head of a 54-year-old woman. She presented with intermittent dysphagia and significant weight loss within a 3-mo period. Laboratory findings showed mild elevation of transaminases, significant elevation of alkaline phosphatase and direct hyperbilirubinemia, indicating obstructive jaundice. Computerized tomography of the abdomen revealed a mass in the head of the pancreas, dilated common bile duct, and dilated pancreatic duct...

INTRODUCTION: Serum gamma glutamyl transferase (GGT), produced and released mostly from the liver and bile duct, is an enzyme involved in response to oxidative stress, and has been used as a maker for prediction of cardiovascular events. Umbilical artery blood flow resistance index, e.g., the systolic/diastolic ratio (S/D ratio) as determined by ultrasound, has been used to assess the fetal intrauterine conditions. While changes of GGT and S/D ratio in preeclampsia are found to be associated with the risk for adverse perinatal outcome, the potential value of combined use of the two measurements for the prediction of adverse perinatal outcome has not been determined...

Background and study aims Linear endoscopic ultrasound (EUS) evaluation of the pancreaticobiliary system usually requires scanning from both the stomach and the duodenum. The feasibility of assessing the complete pancreaticobiliary system from the stomach alone has not been studied. We aimed to conceptualize a system-based approach (the railroad approach) for linear pancreaticobiliary EUS (PB-EUS) and evaluate whether the pancreaticobiliary anatomy could be assessed from the stomach alone. Patients and methods Three maneuvers were conceptualized and evaluated (the alpha maneuver in the stomach, and sigma and xi maneuvers in the duodenum)...

A 26-year-old female, thirteen months postpartum, presented to the emergency department for four weeks of epigastric abdominal pain, pruritus, new onset jaundice, and 11.3 kgs (25 lbs) unintentional weight loss. On examination, she was afebrile, tachycardic, alert, and oriented and had jaundice with scleral icterus. Labs were significant for undetectable TSH, FT4 that was too high to measure, and elevated total bilirubin, direct bilirubin, alkaline phosphatase, and transaminases. Abdominal ultrasound revealed cholelithiasis without biliary ductal dilation...

Alexandra Dili, Claude Bertrand
AIM: To assess the role of laparoscopic ultrasound (LUS) as a substitute for intraoperative cholangiography (IOC) during cholecystectomy. METHODS: We present a MEDLINE and PubMed literature search, having used the key-words "laparoscopic intraoperative ultrasound" and "laparoscopic cholecystectomy". All relevant English language publications from 2000 to 2016 were identified, with data extracted for the role of LUS in the anatomical delineation of the biliary tract, detection of common bile duct stones (CBDS), prevention or early detection of biliary duct injury (BDI), and incidental findings during laparoscopic cholecystectomy...

We report a case of a 48-year-old female patient, who presented with abdominal pain, jaundice, and lack of appetite. Ultrasound showed intrahepatic biliary dilatation with retroperitoneal lymphadenopathy. Further magnetic resonance cholangiopancreatography detected Klatskin tumor. Computed tomography (CT) confirmed the Klatskin tumor with liver metastases and retroperitoneal lymphadenopathy. Biopsy from the hepatic lesion identified mucinous adenocarcinoma, likely originating from bile ducts. Endoscopic retrograde cholangiopancreatography was performed 3 times with stents placed in the left and right hepatic bile ducts...

BACKGROUND: Intraoperative assessment of biliary tract anatomy is relevant for a number of benign and malignant hepatobiliary diseases. During biliary reconstruction, drainage of all relevant bile ducts is imperative to prevent atrophy of undrained segment, cholangitis and secondary biliary cirrhosis. Intraoperative cholangiography, though widely used for intraoperative imaging of the biliary tract, involves heavy equipment use, radiation risk and has a limited role in the evaluation of isolated segmental bile ducts...

Background and study aim Endoscopic ultrasound-guided rendezvous (EUS-RV) is increasingly reported as a treatment option after failed endoscopic retrograde cholangiopancreatography. We developed a novel "hitch-and-ride" catheter for biliary cannulation to reduce the risk of guidewire loss during EUS-RV. Patients and methods We retrospectively evaluated safety and technical success of EUS-RV between June 2011 and May 2016. Biliary cannulation during EUS-RV using three methods - over-the-wire, along-the-wire, and hitch-and-ride - were compared...
