Several studies have assessed nuclear imaging tests for localizing the source of fever in patients with classic fever of unknown origin (FUO); however, the role of these tests in clinical practice remains unclear. We systematically reviewed the test performance, diagnostic yield, and management decision impact of nuclear imaging tests in patients with classic FUO. METHODS We searched PubMed, ...

Although the double contrast barium enema is the standard radiological examination of the colon, it is not universally available to patients referred by their general practitioners. A retrospective survey of all double contrast barium enemas carried out over a two year period in one health district was undertaken to determine the diagnostic yield of pathological findings for patients referred b...

The present study prospectively evaluated the diagnostic yield and safety of electromagnetic navigation-guided bronchoscopy biopsy, for small peripheral lung lesions in patients where standard techniques were nondiagnostic. The study was conducted in a tertiary medical centre on 40 consecutive patients considered unsuitable for straightforward surgery or computed tomography (CT)-guided transtho...

BACKGROUND Studies have reported a high diagnostic yield of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for the diagnosis of sarcoidosis. We sought to review the yield of EBUS-TBNA for the diagnosis of sarcoidosis at our institution over time, and examine factors that may influence this yield. METHODS Patients who underwent EBUS-TBNA for suspected sarcoidosis ...

Background and Aim. Spiral enteroscopy (SE) is a new small bowel endoscopic technique. Our aim is to review the diagnostic and therapeutic yield, safety of SE, and the predictive role of prior capsule endoscopy (CE) at an academic center. Methods. A retrospective review of patients undergoing SE after prior CE between 2008 and 2013 was performed. Capsule location index (CLI) was defined as the ...

STUDY OBJECTIVE To study the diagnostic role of flexible bronchoscopy (FB) in immunocompromised patients with pulmonary infiltrates. DESIGN Prospective, observational study. SETTING Tertiary care hospital. PATIENTS A total of 104 consecutive non-HIV-infected immunocompromised patients with lung infiltrates in whom FB was performed. METHODS The primary outcome measure was the diagnostic ...

BACKGROUND AND STUDY AIMS Two 22G needles with similar designs, apart from the absence (A) or presence of a side port (B), are available for endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA). The side port was designed to increase diagnostic yield but this advantage was unproven. This study evaluated the difference in diagnostic yield between both needles in pancreatic masses. P...

The yield and safety of ultrasound (US)-assisted transthoracic fine needle aspirations (TTFNA) and cutting needle biopsies (CNB) in the setting of superior vena cava (SVC) syndrome are unknown. The aims of the present prospective study were to asses the diagnostic yield and safety of US-assisted TTFNA and CNB in SVC syndrome with an associated mass lesion abutting the chest wall. Over a 3-yr pe...

INTRODUCTION The diagnosis of peripheral pulmonary lesions (PPLs) is a challenging task for pulmonologists. Radial probe endobronchial ultrasound (R-EBUS) has been developed to enhance diagnostic yield. The objective of this study was to evaluate the effectiveness of R-EBUS in the diagnosis of PPLs. METHODS A retrospective study was conducted on 174 patients diagnosed with PPLs who underwent ...
