Wireless capsule endoscopy (WCE) is performed with a miniature swallowable endoscope enabling the visualization of the whole gastrointestinal (GI) tract. One of the most challenging problems in WCE is the localization of the capsule endoscope (CE) within the GI lumen. Contemporary, radiation-free localization approaches are mainly based on the use of external sensors and transit time estimation techniques, with practically low localization accuracy. Latest advances for the solution of this problem include localization approaches based solely on visual information from the CE camera...

Longstanding diabetes mellitus (both type 1 and type 2) can impair gastric motor function and cause significant upper gastrointestinal symptoms which significantly degrade quality of life, cause nutritional deficits, and degrade healthcare resource use. The most commonly considered gut complication of diabetes, diabetic gastroparesis, is a syndrome of delayed gastric emptying in the absence of mechanical obstruction which leads to symptoms of nausea, vomiting, postprandial fullness, early satiation, bloating, and upper abdominal pain...

BACKGROUND: In patients with suspected or known obstructive gastrointestinal pathology, the use of patency capsule (PC) aims to minimize the risk of subsequent retention of the endoscopic capsule. However, its clinical utility is not consensual. The aim was to evaluate the indications, results and safety profile of the PC. METHODS: Retrospective analysis of PCs (Agile patency Capsule) conducted between 2011 and 2015. Patency evaluation was performed after 30 hours, with radiological confirmation if PC was detected...

Wireless pH monitoring of the esophagus has been widely used to detect GERD for more than a decade. It is generally well tolerated and accepted by patients, but it is still unclear whether prolonging a recording beyond the usual 48 hours can improve the test's diagnostic value. The aim of this study is to examine the diagnostic yield of 96-hour pH monitoring vis-à-vis 24- and 48-hour tests, and to ascertain whether any gain in diagnostic terms was of genuine clinical utility. Patients with suspected GERD underwent 4-day PPI-off wireless pH monitoring of the distal esophagus...

Since 2001, small bowel capsule endoscopy (SBCE) has been widely implemented into clinical practice as a minimal-invasive diagnostic approach for diagnosing small bowel diseases. Currently, SBCE is moreover recognized as the first-line procedure for the diagnostic work-up of obscure gastrointestinal bleeding (OGIB) and for a variety of SB disorders including Crohn's disease, inherited polyposis syndromes, suspected small bowel tumors or refractory celiac disease [1,2]. In addition, capsule endoscopy is used to guide the decision whether device assisted enteroscopy (i...

OBJECTIVE Extracapsular resection of pituitary microadenomas improves remission rates, but the application of pseudocapsular techniques for macroadenomas has not been well described. In larger tumors, the extremely thin, compressed normal gland or its complete absence along the tumor's anterior surface limits the application of the traditional pseudocapsular technique that can be used for microadenomas. However, in the authors' experience, the interface between the pseudocapsule at the posterior margin of the adenoma and the compressed normal gland behind it is universally present, providing a surgical dissection plane...

BACKGROUND AND AIMS: Mucosal healing is the goal for ulcerative colitis (UC) therapy, but it needs to be confirmed via colonoscopy. Colon capsule endoscopy (CCE) is a noninvasive technique for colon investigation. Our study investigated the accuracy of second-generation CCE (CCE-2) in assessing mucosal lesions and disease activity in UC. METHODS: In this prospective study, CCE-2 and conventional colonoscopy were performed on the same day. CCE-2 reviewers and colonoscopists used the Mayo endoscopic subscore (MES) and the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) to assess disease activity, and they were blinded to each other's findings...

Although rare, gastrointestinal posttransplant lymphoproliferative disorder (PTLD) can lead to abdominal pain or gastrointestinal bleeding in patients with a history of solid-organ transplantation. We describe a case of isolated gastrointestinal PTLD in a patient who presented with acute on chronic iron deficiency anemia 26 years after heart transplant. A comprehensive endoscopic evaluation with video capsule endoscopy and small bowel enteroscopy revealed a large cratered ulceration in the small bowel with abnormal mucosal changes, which led to the diagnosis of PTLD...

Ganglion cysts are common cystic lesions filled with a jelly-like substance and originate from a joint capsule or tendon sheath through a stalk. Ganglion cysts mostly occur in the hand region, for which surgical excision usually results in good outcomes. In contrast, toe ganglions are relatively rare, and surgical treatment is associated with a high recurrence rate because of unidentifiable ganglion stalks, requiring large skin incisions. We have treated toe ganglion cysts using endoscopy in the ganglion cyst by injecting methylene blue into the tendon sheath that connects to the ganglion stalk...

BACKGROUND AND STUDY AIMS : Lynch syndrome (LS) patients have an increased risk of small bowel cancer. The question is whether surveillance will lead to early detection of (pre)malignant lesions. We recently reported on prevalence of small bowel neoplasia (SBN) in LS patients as assessed by video capsule endoscopy (VCE). The aim of this prospective study was to determine the incidence of SBN. PATIENTS AND METHODS : Asymptomatic LS patients who underwent a VCE were invited to undergo a second VCE procedure 2 years later...

Visibility in capsule endoscopic images is presently evaluated through intermittent analysis of frames selected by a physician. It is thus subjective and not quantitative. A method to automatically quantify the visibility on capsule endoscopic images has not been reported. Generally, when designing automated image recognition programs, physicians must provide a training image; this process is called supervised learning. We aimed to develop a novel automated self-learning quantification system to identify visible areas on capsule endoscopic images...

Chronic encapsulated intracerebral hematoma (CEIH) is a rare cerebrovascular disease. Here, we describe a case of a patient with alcoholic cirrhosis and an abnormal coagulation state that was treated with minimally invasive endoscopic hematoma removal. A 54-year-old man presented with a 2-week history of incoherent speech, incontinence, and repeated stumbling. Laboratory analysis showed thrombocytopenia and the prolongation of prothrombin time due to alcoholic cirrhosis. Computed tomography and magnetic resonance imaging showed a large mass in the left parieto-occipital lobe suggesting a hematoma...

The current International Organization for Standardization (ISO) standard (ISO 8600-3: 1997 including Amendment 1: 2003) for determining endoscope field of view (FOV) does not accurately characterize some novel endoscopic technologies such as endoscopes with a close focus distance and capsule endoscopes. We evaluated the endoscope FOV measurement method (the FOVWS method) in the current ISO 8600-3 standard and proposed a new method (the FOVEP method). We compared the two methods by measuring the FOV of 18 models of endoscopes (one device for each model) from seven key international manufacturers...
