Cost-effective imaging for resectability of liver lesions in colorectal cancer: an economic decision model.

Background: This study aimed to determine the cost-effectiveness of contrast-enhanced magnetic resonance imaging (CE-MRI) compared with multiphase CE computed tomography (CE-CT) scan to characterize suspected liver lesions in patients with known colorectal carcinoma.

Methods: A decision analytic model linking diagnostic accuracy to health outcomes in patients with colorectal carcinoma was constructed. The model assumed that CE-MRI has superior sensitivity and equivalent specificity to CE-CT, and patients with a colorectal liver metastasis could be eligible for curative surgery or chemotherapy and palliation.

Clinical safety and effectiveness of transversus abdominis plane (TAP) block in post-operative analgesia: a systematic review and meta-analysis.

Transversus abdominis plane (TAP) blocks can provide analgesia postoperatively for a range of surgeries. Abundant clinical trials have assessed TAP block showing positive analgesic effects. This systematic review assesses safety and effectiveness outcomes of TAP block in all clinical settings, comparing with both active (standard care) and inactive (placebo) comparators.

Comparative diagnostic accuracy of hepatocyte-specific gadoxetic acid (Gd-EOB-DTPA) enhanced MR imaging and contrast enhanced CT for the detection of liver metastases: a systematic review and meta-analysis.

Purpose: This systematic review evaluated the diagnostic accuracy and impact on patient management of hepatocyte-specific gadoxetic acid enhanced magnetic resonance imaging (GA-MRI) compared to contrast enhanced computed tomography (CE-CT) in patients with liver metastases.

Method: Four biomedical databases (PubMed, EMBASE, Cochrane Library, York CRD) were searched from January 1991 to February 2016. Studies investigating the accuracy or management impact of GA-MRI compared to CE-CT in patients with known or suspected liver metastases were included.

Gadoxetic acid-enhanced MRI for the characterization of hepatocellular carcinoma: A systematic review and meta-analysis.

Purpose: To establish the relative diagnostic accuracy of gadoxetic acid-enhanced magnetic resonance imaging (GA-MRI) compared with contrast-enhanced computed tomography (CE-CT), dynamic MRI (D-MRI), gadopentetic acid-enhanced MRI (GP-MRI), or gadobenic acid-enhanced MRI (GB-MRI) in the characterization of hepatocellular carcinoma (HCC).

Materials And Methods: PubMed, EMBASE, the Cochrane Library, and the University of York CRD databases were searched to February 29 2016 for any studies that compared the diagnostic accuracy of GA-MRI to CE-CT, D-MRI, GP-MRI, or GB-MRI in patients with known or suspected HCC. Diagnostic accuracy outcomes (true positive, true negative, false positive, false negative) were extracted and analyzed using the bivariate model of Reitsma et al (2005).

Continuous paravertebral block for post-cardiothoracic surgery analgesia: a systematic review and meta-analysis.

A continuous paravertebral block is used when pain relief is required beyond the duration of a single-injection paravertebral block. Surgical procedures requiring an incision into the pleural cavity are some of the most painful procedures postoperatively and, if not managed appropriately, can lead to chronic pain. The current gold standard for post-cardiothoracic surgery pain management is epidural analgesia, which has contraindications, a failure rate of up to 12% and risk of complications such as epidural abscess and spinal haematoma.

Stereotactic anatomical localization in complex sinus surgery: A systematic review and meta-analysis.

Objective: It is recognized that stereotactic anatomical localization (SAL) is a useful tool in endoscopic sinus surgery (ESS), but it may be most beneficial for complex rather than routine sinus procedures. This review sought to determine the safety and efficacy of SAL in complex indications for ESS.

Data Sources: PubMed, EMBASE, Centre for Reviews and Dissemination, and the Cochrane Library were searched from inception up to April 4, 2014.

Systematic review of hyperbaric oxygen therapy for the treatment of non-neurological soft tissue radiation-related injuries.

Purpose: The purpose of this paper was to provide an evidence-based evaluation of the safety and effectiveness of hyperbaric oxygen therapy (HBOT) for the treatment of non-neurological soft tissue radiation-related injuries (STRI).

Methods: Systematic searches of medical bibliographic databases, the Internet, and lists of references were conducted in December 2010 and April 2013 to identify relevant primary studies. Inclusion and classification of papers was resolved through the application of a predetermined protocol.

Systematic review of computer-navigated total knee arthroplasty.

Background: Conventional total knee arthroplasty (TKA) and the more recently available computer-navigated total knee arthroplasty (CNTKA) use alternative methods to achieve correct limb alignment. This systematic review was undertaken to assess the safety and effectiveness of CNTKA compared with conventional TKA.

Methods: A systematic search of multiple databases identified relevant randomized controlled trials published to August 2012.

Deep brain stimulation for essential tremor: a systematic review.

Deep brain stimulation (DBS) is a neurosurgical treatment, which has proven useful in treating Parkinson's disease. This systematic review assessed the safety and effectiveness of DBS for another movement disorder, essential tremor. All studies concerning the use of DBS in patients with essential tremor were identified through searching of electronic databases and hand searching of reference lists.
