BACKGROUND: A patency capsule (PC) can help predict capsule endoscope (CE) retention; however, PC tolerability is unknown in children. We retrospectively evaluated PC tolerability in school-aged children. METHODS: Sixty-one patients (median age, 12.9 years; range 7.4-17.3 years) who underwent PC examination were analyzed for occurrence and determinants of ingestion difficulty and relationships between ingestion of the 2 capsules. We defined ingestion difficulty as taking 30 min or more, or failure, to ingest the PC...

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal-dominant disorder leading to telangiectases and arteriovenous malformations of the skin, mucosa, and viscera. Telangiectases in the upper gastrointestinal tract are known, but data regarding possible small-bowel involvement are poor. AIMS: To evaluate the role of capsule endoscopy (CE) to determine the prevalence of small-bowel telangiectases in HHT patients, and the role of endoscopic treatment of these patients with particular reference to the incidence of re-bleeding after treatment...

Among the various diagnostic modalities for small bowel hemangioma, video capsule endoscopy (VCE) and double-balloon enteroscopy (DBE) can be recommended as part of the work-up in patients with obscure gastrointestinal bleeding (OGIB). DBE is superior to VCE in the accuracy of diagnosis and therapeutic potential, while in most cases total enteroscopy cannot be achieved through only the antegrade or retrograde DBE procedures. As treatment for small bowel bleeding, especially spout bleeding, localization of the lesion for the decision of DBE insertion facilitates early treatment, such as endoscopic hemostatic clipping, allowing patients to avoid useless transfusion and the worsening of their disease into life-threatening status...

Video capsule endoscopy (VCE) has been of immense benefit in the diagnosis and management of gastrointestinal (GI) disorders since its introduction in 2001. However, it suffers from a number of well recognized deficiencies. Amongst these is the limited capability of white light imaging, which is restricted to analysis of the mucosal surface. Current capsule endoscopes are dependent on visual manifestation of disease and limited in regards to transmural imaging and detection of deeper pathology. Ultrasound capsule endoscopy (USCE) has the potential to overcome surface only imaging and provide transmural scans of the GI tract...

Obscure gastrointestinal bleeding (OGIB) accounts for approximately 5% of all gastrointestinal (GI) hemorrhages. It usually arises from a small bowel lesion beyond the reach of conventional endoscopy including esophagogastroduodenoscopy and colonoscopy. Video capsule endoscopy (VCE) revolutionized the evaluation of OGIB patients since it allows reliable and noninvasive visualization of the small bowel mucosal surface. Since 2001, VCE has evolved into an efficient technology integrated in clinical practice. It is the cornerstone in the algorithm of OGIB investigation given its high diagnostic yield, which compares favorably to that of double-balloon enteroscopy (DBE)...

Gastrointestinal angiodysplasia (GIA) is an acquired vascular superficial lesion, which presents typically as a bright red, irregular, round-shaped, slightly elevated lesion. GIAs are often seen in patients over 60 years of age and are mostly located in the colon (cecum and ascending).The cause and mechanisms of GIA have yet to be completely understood. Small-bowel GIAs are often diagnosed in the setting of obscure gastrointestinal bleeding (OGIB). In some cases, GIAs are associated with aortic stenosis, Von Willebrand's disease, chronic renal disease, and liver disease...

One of the significant challenges in Capsule Endoscopy (CE) is to precisely determine the pathologies location. The localization process is primarily estimated using the received signal strength from sensors in the capsule system through its movement in the gastrointestinal (GI) tract. Consequently, the wireless capsule endoscope (WCE) system requires improvement to handle the lack of the capsule instantaneous localization information and to solve the relatively low transmission data rate challenges. Furthermore, the association between the capsule's transmitter position, capsule location, signal reduction and the capsule direction should be assessed...

HIV infection is reportedly associated with an increased permeability of the intestinal epithelium and can cause HIV enteropathy, which occurs independently of opportunistic infections. However, the characteristics of small bowel abnormalities attributable to HIV infection are rarely investigated. In the present study, we assessed the intestinal mucosal changes found in HIV-infected patients and compared them with the mucosa of healthy control subjects using capsule endoscopy (CE). Three of the 27 HIV-infected patients harbored gastrointestinal opportunistic infections and were thus excluded from subsequent analyses...
