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...

BACKGROUND: Patients are at increased risk of disease recurrence after surgical treatment of Crohn's disease. Endoscopic detection of postoperative, ileo-colonic inflammation is well established, but the potential of pan-intestinal endoscopy is yet unknown. METHODS: This prospective multicenter pilot study assessed the value of pan-intestinal capsule endoscopy using a colon capsule endoscope for the detection of inflammatory recurrence of Crohn´s disease. Patients who had been operatively treated for Crohn´s disease were included...

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...

In this paper, we demonstrate velocity-level closed-loop control of a tethered magnetic capsule endoscope that is actuated via serial manipulator with a permanent magnet at its end-effector. Closed-loop control (2 degrees-of-freedom in position, and 2 in orientation) is made possible with the use of a real-time magnetic localization algorithm that utilizes the actuating magnetic field and thus does not require additional hardware. Velocity control is implemented to create smooth motion that is clinically necessary for colorectal cancer diagnostics...

Magnetic field gradients have repeatedly been shown to be the most feasible mechanism for gastrointestinal capsule endoscope actuation. An inverse quartic magnetic force variation with distance results in large force gradients induced by small movements of a driving magnet; this necessitates robotic actuation of magnets to implement stable control of the device. A typical system consists of a serial robot with a permanent magnet at its end effector that actuates a capsule with an embedded permanent magnet. We present a tethered capsule system where a capsule with an embedded magnet is closed loop controlled in 2 degree-of-freedom in position and 2 degree-of-freedom in orientation...

PURPOSE OF REVIEW: The costs to society and accuracy of screening for esophageal cancer and other esophageal diseases with standard endoscopy are formidable. As a result, the applicability of endoscopy as a general screening tool has been challenged. RECENT FINDINGS: To maintain accuracy but reduce the price of endoscopy on society, multiple adjunct or replacement technologies are being developed that are less expensive and more easily applied. These devices include image-enhancing techniques that more reliably identify dysplasia and cancer reducing the need for extensive biopsy sampling during standard endoscopy...

A 28-year-old Caucasian man was admitted in our unit for acute massive rectal bleeding. Past medical and family history was unremarkable. Hemoglobin was 7.6 g/dL. Blood transfusions were required. Computed tomography and gastrointestinal endoscopy were negative for active bleeding. When patient's hemoglobin was normalized and stable, a video capsule endoscopy was performed. Video relieved the presence of multiple digiunal and ileal angiodysplastic lesions. A double endoscopic argon plasma coagulation procedure was planned on general anaesthesia...

Small-bowel capsule endoscopy (CE) has recently been used in children. During the past few years, an intense research activity has defined the advantages and limitations of CE. Its uses have been established in several small-bowel pathologies such as obvious or obscure digestive bleeding, Crohn disease, and hereditary polyposis. Although the absence of biopsy reduces the specificity of CE findings, small-bowel exploration using CE achieves better accuracy in detecting lesions than most radiological examinations...

An efficient and automated abnormality detection method can significantly reduce the burden of screening of the enormous visual information resulting from capsule endoscopic procedure. As a pre-processing stage, color enhancement could be useful to improve the image quality and the detection performance. Therefore, in this paper, we have proposed a two-stage automated abnormality detection algorithm. In the first stage, an adaptive color enhancement method based on Retinex theory is applied on the endoscopic images...

Lipomas of the gastrointestinal tract are extremely rare, slow-growing and most often asymptomatic tumours. They are composed of highly differentiated fat cells surrounded by a fibrous capsule. Tumours larger than 2 cm can produce symptoms of abdominal pain and discomfort or cause anaemia due to ulceration and bleeding, or intestinal obstruction due to intussusception. This is a case report of a 73-year-old man with a bleeding duodenal lipoma situated at the papilla duodeni major which caused difficulty in the diagnostic process, and the endoscopic visualization raised suspicion of cancer of the papilla...
