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...

INTRODUCTION: Capsule endoscopy (CE) has an excellent safety profile. Although retention is the most cited complication, capsule aspiration is less frequent and is often reported only as isolated cases. This study represents a systematic effort to compile and scrutinize the available data on capsule aspiration to provide comprehensive and conclusive information on this CE complication. MATERIALS AND METHODS: A systematic literature search was performed in PubMed, Embase and Chinese National Knowledge Infrastructure...

Pyogenic granuloma is a non-infectious and non-granulomatous lesion. Its location in the small bowel is very rare. We present a 46 year-old woman with a chronic liver disorder that had a severe chronic anemia with occult blood losses. Upper endoscopy and colonoscopy were normal. A small bowel capsule endoscopy showed a pyogenic granuloma in jejunum that was resected endoscopically with single balloon enteroscopy with no major complications. The patient recovered from anemia and six months latter capsule endoscopy did not show lesions...

BACKGROUND: Helicobacter pylori (HP) infection is present in about 50% of the global population, and is associated with chronic gastritis, peptic disease and gastric malignancies. HP prevalence in Crohn's disease (CD) patients was shown to be low compared to the general population, and its influence on disease activity is yet to be determined. Our aims were to determine the prevalence of HP in a selected group of CD patients with quiescent disease, and to assess the influence of its eradication on disease activity and endoscopic and laboratory activity measures...

INTRODUCTION: Bariatric procedures result in massive weight loss, however, not without side effects. Gastric acid is known to cause marginal ulcers, situated in the small bowel just distal to the upper anastomosis. We have used the wireless BRAVO™ system to study the buffering effect of the duodenal bulb in duodenal switch (DS), a procedure in which the gastric sleeve produces a substantial amount of acid. METHODS: We placed a pre- and a postpyloric pH capsule in 15 DS-patients (seven men, 44 years, BMI 33) under endoscopic guidance and verified the correct location by fluoroscopy...

Adhesive capsulitis of the ankle is also known as frozen ankle and results in marked fibrosis and contracture of the ankle capsule. Arthroscopic capsular release is indicated for symptomatic frozen ankle that is resistant to conservative treatment. It is contraindicated for ankle stiffness due to degenerative joint disease, intra-articular malunion, or adhesion of the extensors of the ankle. The procedure consists of endoscopic posterior ankle capsulectomy and arthroscopic anterior ankle capsulotomy. It has the advantages of being minimally invasive surgery and allowing early postoperative vigorous mobilization of the ankle joint...

The cavernous venous malformation of the orbit, previously called cavernous hemangioma, is the most common primary orbital lesion of adults. Cavernous venous malformation occurs more often in women and typically presents in the fourth and fifth decades of life. It is a benign vascular malformation characterized by a well-defined capsule and numerous large vascular channels. The most common sign of cavernous venous malformation is progressive axial proptosis from the preferential involvement of the intraconal orbital space...

AIM: To evaluate the role of small bowel capsule endoscopy (SBCE) on the reclassification of colonic inflammatory bowel disease type unclassified (IBDU). METHODS: We performed a multicenter, retrospective study including patients with IBDU undergoing SBCE, between 2002 and 2014. SBCE studies were reviewed and the inflammatory activity was evaluated by determining the Lewis score (LS). Inflammatory activity was considered significant and consistent with Crohn's disease (CD) when the LS ≥ 135...
