Zhe Shen, Stefan Munker, Boyan Zhou, Lin Li, Chaohui Yu, Youming Li
Magnetic resonance cholangiopancreatography (MRCP), MRCP after secretin stimulation (S-MRCP) and endoscopic ultrasonography (EUS) are all selected to diagnose pancreas divisum. However, the accuracies of three diagnosis remain unclear. The aim is to address the diagnostic accuracies of MRCP, S-MRCP and EUS on pancreas divisum. We searched PubMed, MEDLINE and EMBASE databases from inception to January, 2015. Of the 536 citations retrieved, 16 studies were included. For MRCP diagnosis on pancreas divisum, the area under the hierarchical summary receiver-operating characteristic (HSROC) curve was 0...

BACKGROUND: Esophageal cancer is considered a serious malignancy with respect to its prognosis and mortality rate. Cervical lymph node status is one of the keys to determining prognosis and treatment methods. However, published data vary regarding the accuracy of ultrasound in the diagnosis of cervical lymph node metastasis. We performed a meta-analysis to assess the efficacy of ultrasound for detecting cervical lymph node metastasis in patients with esophageal cancer. METHODS: The PubMed/MEDLINE, EMBASE, Web of Science, and Cochrane Library databases were searched to identify studies related to cervical lymph node metastasis, and 22 studies comprising 3,513 patients met our inclusion criteria...

BACKGROUND: Previous studies have demonstrated that endoscopic ultrasound-fine needle aspiration (EUS-FNA) is a reliable tool for diagnosing pancreatic lesions; however, the reported sensitivity and specificity vary greatly across studies. The aim of this study was to pool the existing literature and assess the overall performance of EUS-FNA in the diagnosis of solid pancreatic lesions. METHODS: A systematic search of MEDLINE, Cochrane Database for Systematic Reviews, and EMBASE was performed to identify original and review articles published between January 1995 and January 2014 that reported the accuracy of EUS-FNA in the diagnosis of pancreatic masses...

INTRODUCTION: There are currently no guidelines supporting the use of routine chemoprophylaxis to prevent deep vein thrombosis (DVT) in arthroscopic surgery. Studies and meta-analysis show opposing views on its routine use in arthroscopy. This study aimed to examine the incidence of DVT in a prospective cohort of knee arthroscopy and knee arthroplasty patients, and to analyse the risk factors contributing to DVT. METHODS: All patients scheduled to undergo knee arthroscopy or arthroplasty over a two-year period were included...

Background/Aims: We identified reports in the literature regarding the diagnostic accuracy of hepatic vein arrival time (HVAT) measured by contrast-enhanced ultrasonography (CEUS) to assess hepatic fibrosis in cirrhosis. Methods: The Ovid MEDLINE, Embase, and Cochrane databases were searched for all studies published up to 23 July 2015 that evaluated liver status using CEUS and liver biopsy (LB). The QUADAS-II (quality assessment of diagnostic accuracy studies-II) was applied to assess the internal validity of the diagnostic studies...

BACKGROUND: Crohn disease (CD) is a chronic relapsing disease. Imaging modalities are essential for the diagnosis and assessment of CD. Small intestine contrast ultrasonography (SICUS) is a well-tolerated, noninvasive and radiation-free modality and has shown potential in CD assessment. We aimed at evaluating the diagnostic accuracy of SICUS in the detection and assessment of small-bowel lesions and complications in CD. METHODS: We searched PubMed database for relevant studies published before April 24, 2016...

BACKGROUND & AIMS: Even though propofol use for gastrointestinal endoscopic procedures has increased over the past decade, there is a perception that it causes a higher rate of cardiopulmonary adverse events. The aim of this study was to compare the sedation-related adverse events associated with use of propofol vs nonpropofol agents for endoscopic procedures. We also wanted to determine the influence of duration or complexity of the procedures and endoscopist-directed (gastroenterologist) vs non-gastroenterologist-directed sedation on the outcomes...

Diverticular disease (DD) of the colon has an increasing burden on health service resources, in terms of hospital admissions, mortality and surgery rate. We present an overview of the clinical history of DD, and of the ways that gastroenterologists have to modify it. Prevalence of the disease increases with aging. Most of diverticulosis are occasionally identified on colonscopy, and most of them remain asymptomatic for all life. Only 4% of these subjects develop diverticulitis. However, 4-25% of these patients are expected to present a second episode of diverticulitis, and 15% of them develop complications...

Early detection and treatment of this injury is of utmost importance in prognosis of the patient, but there are still controversial debates on the diagnostic value of imaging techniques in detection of hemothorax. Therefore, the present study aimed to evaluate the diagnostic value of chest ultrasonography and radiography in detection of hemothorax through a systematic review and meta-analysis. METHODS: Two independent reviewers performed an extended systematic search in databases of Medline, EMBASE, ISI Web of Knowledge, Scopus, Cochrane Library, and ProQuest...

We compared the efficacy of contrast-enhanced ultrasound (CEUS) and contrast-enhanced computed tomography (CECT) for the diagnosis of renal cystic lesions via a meta-analysis to determine the value of CEUS in the prediction of the malignant potential of complex renal cysts. Eleven studies were evaluated: 4 control studies related to CEUS and CECT, 3 studies related to CEUS and 4 studies related to CECT. According to the random effects model, the pooled sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio for CEUS/CECT were 0...

ATP Binding Cassette Transporter A4 (ABCB4) is a sterol export pump that regulates excretion of biliary cholesterol. We tested association between ABCB4 polymorphisms and gallstone disease using meta-analysis. In a cross-sectional study, 296 subjects were recruited from a hospital-based population. Total of 171 subjects were diagnosed as gallstone disease by abdominal ultrasonography from three cohort studies. We evaluated prevalence of ABCG8 rs11887534 (D19H) as a positive control, and the ABCB4 rs1202283 and rs2230028 polymorphisms on Chinese population were screened by meta-analysis and genotyped using TaqMan® SNP assay...
