In this article, we investigate the suitability of wireless technologies in healthcare/hospital environments. We focus on Wireless Personal Area Network technologies, namely, Bluetooth and the low-rate specifications described in the IEEE 802.15.4 standard. We evaluate the relevance of each technology for supporting medical applications and examine related scalability issues. Moreover, we consi...

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal (GI) tract, affecting about 2% of the population. Most cases of Meckel's diverticula are asymptomatic. The diagnosis of symptomatic MD is often difficult to make. We report the case of an 8-year-old boy who presented with GI bleeding due to MD. The diagnostic difficulties after an initial negative endoscopi...

BACKGROUND AND AIMS Capsule endoscopy is applicable to several clinical conditions, but obscure gastrointestinal bleeding remains the main indication. This study aims at determining the diagnostic yield of capsule endoscopy for obscure gastrointestinal bleeding using a structured terminology in a large cohort in an academic hospital. METHODS In this retrospective study, 592 capsule endoscopy ...

BACKGROUND AND STUDY AIMS Capsule endoscopy (Pillcam Colon) has recently shown acceptable accuracy in detecting colonic lesions when compared with colonoscopy. The aim of this analysis is to provide a model to assess the cost and effectiveness of population-based screening for colorectal cancer (CRC) using capsule endoscopy and to compare the cost-effectiveness with that of a colonoscopy screen...

BACKGROUND AND STUDY AIMS Early diagnosis of small-bowel tumors is crucial for therapy. Video capsule endoscopy has improved the diagnosis of small-bowel diseases, but data concerning the role of this technique in detecting small-bowel malignancy are scarce. The aim of this paper was to review all capsule endoscopy findings at Belgian hospitals, in order to evaluate the diagnostic yield of caps...

The narrow bandwidth at low frequency of current available wireless capsule endoscopy do not provide clear images of digestive organs. The Ultra Wideband (UWB) at frequency of 3.1-10.6 GHz is one of the possible frequency band to provide clear images from small intestine and stomach. This paper discusses on an UWB antenna to be placed inside stomach of a human body model.
