Since first described in 2000 [1], capsule endoscopy has established itself as a noninvasive investigative modality of the gastrointestinal tract. It is used as a first-line investigation to image a variety of diseases of the small bowel. These include common conditions, such as coeliac disease, and rare diseases, such as familial adenomatous polyposis, both discussed in detail in this special ...

BACKGROUND AND STUDY AIMS  Small bowel cancer is rare, accounting for < 5 % of all gastrointestinal neoplasms. Capsule endoscopy has become the procedure of choice for non-invasive diagnosis of small bowel diseases. Data on capsule endoscopy diagnosis of small bowel cancer are limited. The objective of the study was to determine the frequency, indications and diagnostic work-up of patients with...

INTRODUCTION Perforation caused by capsule endoscopy impaction is extremely rare and, at present, only five cases of perforation from capsule endoscopy impaction are reported in the literature. CASE PRESENTATION We report here two cases of patients with undiagnosed small bowel stenosis presenting with acute perforation after capsule endoscopy. Strictures in the small bowel were likely the inc...

A prototype of a vision system for capsular endoscopy provided with autofocus function was developed. It is composed by two main parts: a wireless capsule with an adjustable focus in the range between 15 mm and 100 mm, and a personal computer where the autofocus algorithm is implemented. Several benches and ex vivo tests were performed in order to validate the developed system and encouraging r...

BACKGROUND Colorectal cancer is a leading cause of mortality and morbidity in Ontario. Most cases of colorectal cancer are preventable through early diagnosis and the removal of precancerous polyps. Colon capsule endoscopy is a non-invasive test for detecting colorectal polyps. OBJECTIVES The objectives of this analysis were to evaluate the cost-effectiveness and the impact on the Ontario hea...

Wireless Video Capsule Endoscopy is a clinical technique consisting of the analysis of images from the intestine which are provided by an ingestible device with a camera attached to it. In this paper we propose an automatic system to diagnose severe intestinal motility disfunctions using the video endoscopy data. The system is based on the application of computer vision techniques within a mach...

Until recently, the small bowel was considered a 'no man's land' as the imaging modalities available for its investigation were laborious, invasive, costly, or involve significant radiation exposure. Wireless capsule endoscopy (WCE) has changed the field dramatically, over the last eight years. The established indications for small bowel WCE are obscure gastrointestinal bleed/anemia, Crohn's di...
