Abstract The paper presents the concept of a low-power, low-area, near-lossless image compressor for resource-constrained devices such as wireless capsule endoscopy (WCE). directly processes raw data from Bayer Color Filter Array (CFA) imager to avoid high cost color interpolation. To improve efficiency in terms energy consumption, silicon area and compression ratio, main part compressor, i.e.,...

Conventional endoscopic exams do not allow the entire visualization of the gastrointestinal (GI) tract. Push enteroscopy (PE) is an effective diagnostic and therapeutic procedure, although it only allows exploration of the proximal small bowel (Pennazio et al., 1995). Simultaneously, convetional colonoscopy is limited at the terminal ileum. Therefore, prior to the wireless capsule endoscopy era...

INTRODUCTION Small bowel capsule endoscopy is currently the first line diagnostic examination for many diseases affecting the small bowel. This article aims to review and critically address the current indications of small bowel capsule endoscopy in clinical practice. MATERIAL AND METHODS Bibliographic review of relevant and recent papers indexed in PubMed. RESULTS AND DISCUSSION Small bowe...

We report a case of a 57-year-old woman with an obscure gastrointestinal bleed who was found to have an extramural gastrointestinal stromal tumour (GIST), detected by capsule endoscopy, and confirmed by laparoscopically-assisted enteroscopy and resection. Currently, major modalities used for detection of GISTs include double-balloon enteroscopy, capsule endoscopy and CT. Endoscopic measures, in...

BACKGROUND Capsule endoscopy is a first line examination to evaluate obscure gastrointestinal bleeding. The identification of factors associated with the detection of lesions by capsule endoscopy could improve resource utilization and patient selection. OBJECTIVES To identify factors associated with positive capsule endoscopy findings in patients with obscure gastrointestinal bleeding. METH...
