STUDY OBJECTIVES To evaluate factors affecting the diagnostic yield of flexible fiberoptic bronchoscopy in evaluating solitary pulmonary nodules (SPNs). DESIGN Retrospective analysis of bronchoscopies performed over a 4-year period. SETTING A tertiary teaching hospital. PATIENTS One hundred seventy-seven patients with pulmonary nodules without endobronchial lesions who underwent bronchosc...

Based on the option that ultrasound-guided core needle biopsy (US-CNB) of the enhanced portion of anterior mediastinal masses (AMMs) identified by contrast-enhanced ultrasound (CEUS) would harvest viable tissue and benefit the histological diagnoses, a retrospective study was performed to elucidate the correlation between the prebiopsy CEUS and diagnostic yield of AMMs and found that CEUS poten...

The purpose of this study was to review economic considerations related to establishing a diagnosis of Crohn's disease, and to compare the costs of a diagnostic algorithm incorporating wireless capsule endoscopy (WCE) with the current algorithm for diagnosing Crohn's disease suspected in the small bowel. Published literature, clinical trial data on WCE in comparison to other diagnostic tools, a...

Objective To evaluate the value of multiple guided technologies based on radial probe endobronchial ultrasound (R-EBUS) in the application of the diagnosis of solitary pulmonary peripheral lesions (PPLs). Methods Analysis of diagnostic yield in 4 groups patients with different combined multiple guided technologies based on R-EBUS, 94 patients with 94 solitary PPLs from Mar, 2013 to Nov, 2014 in...

Introduction Chronic abdominal pain (CAP) is one of the most common indications of esophagogastroduodenoscopy (EGD) in the pediatric population. However, there is not enough information about the diagnostic yield of EGD in children with CAP. We aimed to evaluate the diagnostic yield of EGD in children with CAP in the Eastern Black Sea region of Turkey. Material and methods The study included ...

BACKGROUND Globus sensations, hoarseness and chronic cough are suggested to be atypical manifestations of Gastroesophageal Reflux Disease (GERD). The aim of the study was to investigate whether combined pH-metry and multichannel intraluminal impedance monitoring increases the diagnostic yield. METHODS 41 patients with atypical GERD symptoms were included in the study. Globus sensation was the...

BACKGROUND Device-assisted enteroscopies (DAEs) are recent endoscopic techniques that enable direct endoscopic small-bowel evaluation. OBJECTIVE The objective of this article is to evaluate the implementation of DAEs in Portugal and assess the main indications, diagnoses, diagnostic yield, therapeutic yield and complication rate. METHODS We conducted a multicenter retrospective series using...

Multiple guidance modalities may be combined during bronchoscopic investigation of peripheral pulmonary lesions (PPLs). The relative contribution of each modality to diagnostic performance remains uncertain.Endobronchial ultrasound (EBUS) with virtual bronchoscopy (VB) was routinely performed, with electromagnetic navigation (EMN) utilised only where EBUS was unable to locate PPLs or where the ...

UNLABELLED Edema of the limbs is a common reason for medical consultation, for which the lymphoscintigraphy is considered to be a reliable method for its differential diagnosis. OBJECTIVE To evaluate the usefulness of radionuclide studies in the differential diagnosis of edema, and the diagnostic yield of different scintigraphic patterns. MATERIAL AND METHODS A total of 61 patients, mean ag...

OBJECTIVE To perform a systematic review to analyze the diagnostic yield of magnetic resonance imaging (MRI) for pediatric hearing loss, including comparison to computed tomography (CT) and subgroup evaluation according to impairment severity and specific diagnostic findings (cochlear anomalies, enlarged vestibular aqueduct, cochlear nerve abnormalities, and brain findings). DATA SOURCES Pubm...
