Primary intestinal lymphangiectasia (PIL), Waldmann's disease, is a rare disorder of unknown etiology characterized by dilated intestinal lacteals leading to lymph leakage into the small-bowel lumen and responsible for protein-losing enteropathy leading to lymphopenia, hypoalbuminemia and hypogammaglobulinemia. PIL is generally diagnosed before 3 years of age but may be diagnosed in older patients. The main symptom is bilateral lower limb edema. Edema may be moderate to severe including pleural effusion, pericarditis or ascites...

Celiac disease is diagnosed in part by finding areas of pathology in the small bowel (SB) mucosa. This can often be difficult because the pathologic alterations, including atrophy of the small intestinal villi, can often be sparse and subtle. Some of the quantitative methods for detecting and measuring the presence of villous atrophy from videocapsule endoscopy (VCE) images are presented and discussed. These methods consist of static features of measurement including texture, gray level, and presence and abundance of fissures contained within each acquired image...

BACKGROUND: Celiac disease is one of the most common diseases in the world. Capsule endoscopy is an alternative way to visualize the entire small intestine without invasiveness to the patient. It is useful to characterize celiac disease, but hours are need to manually analyze the retrospective data of a single patient. Computer-aided quantitative analysis by a deep learning method helps in alleviating the workload during analysis of the retrospective videos. METHOD: Capsule endoscopy clips from 6 celiac disease patients and 5 controls were preprocessed for training...

BACKGROUND AND AIMS: As already known, spondyloarthritis patients present a striking resemblance in intestinal inflammation with early Crohn's disease. Moreover, the frequent use of nonsteroidal anti-inflammatory drugs is an important part of their treatment. Both conditions could lead to intestinal stenoses. Therefore we proposed to investigate the usefulness of the patency capsule test in patients with spondyloarthritis. MATERIAL AND METHODS: 64 consecutive patients (33 males; mean age 38 ± 11 years) that fulfilled the AMOR criteria for seronegative spondyloarthropathy (59...

BACKGROUND & AIMS: Considering the ability of anti-TNF alpha drugs to lower the burden intestinal inflammation in patients with inflammatory bowel disease (IBD), and the similarity between IBD and ankylosing spondylitis (AS) regarding inflammatory intestinal involvement, we aimed to investigate the impact of anti-TNF alpha biologic therapy on subclinical intestinal inflammation in AS patients. METHODS: Between January 2008 and December 2013, 38 AS patients and 23 controls were enrolled in the study and investigated with small bowel videocapsule endoscopy examination and ileocolonoscopy...

BACKGROUND/AIMS: Videocapsule endoscopy (VCE) and double-balloon endoscopy (DBE) allow deep exploration in patients with suspected small bowel pathology. VCE is often performed as an initial small bowel examination to explore whether an intervention by DBE is indicated and to determine insertion route. The study aim was to evaluate the correlation between DBE and VCE in patients with obscure or overt bleeding or anemia, as well as intervention frequency, and complications. METHODS: Retrospective observational study...

BACKGROUND: Videocapsule endoscopy is a relative new method to analyze the gastrointestinal tract for the presence of pathologic features. It is of relevance to detect villous atrophy in the small bowel, which is a defining symptom of celiac disease. METHOD: In this tutorial, methods to extract and process videocapsule endoscopy data are elucidated. The algorithms, computer code, and paradigms to analyze image series are described in detail. The topics covered include extraction of data, analysis of texture, eigenanalysis, spectral analysis, three-dimensional projection, and estimation of motility...

BACKGROUND AND AIMS: Fecal calprotectin is a well-established marker of mucosal inflammation. Although the correlation of elevated calprotectin levels with colonic inflammation has been confirmed repeatedly, it is less established for the small bowel. The aim of the current study was to assess the diagnostic accuracy of calprotectin for the prediction of active small-bowel disease on capsule endoscopy by performing a diagnostic test meta-analysis. MATERIALS AND METHODS: A comprehensive search was performed using PubMed/Embase...

BACKGROUND AND STUDY AIMS: In videocapsule endoscopy examination (VCE), subtle variations in mucosal hue or pattern such as those seen in ulcerations can be difficult to detect, depending on the experience of the reader. Our aim was to test whether virtual chromoendoscopy (VC) techniques, designed to enhance the contrast between the lesion and the normal mucosa, could improve the characterization of ulcerative mucosal lesions. PATIENTS AND METHODS: Fifteen trainees or young gastroenterologists with no experience in VCE were randomly assigned to evaluate 250 true ulcerative and 100 false ulcerative, difficult-to-interpret small bowel lesions, initially as white light images (WLI) and then, in a second round, with the addition of one VC setting or again as WLI, labeling them as real lesions or artifacts...

BACKGROUND: Blue rubber bleb nevus syndrome (BRBNS) is a rare disease characterized by vascular malformations mostly involving skin and gastrointestinal tract. This disease is often associated with sideropenic anemia and occult bleeding. METHODS: We report the case of chronic severe anemia in an old patient under oral anticoagulation treatment for chronic atrial fibrillation. RESULTS: At admission, the patient also presented fever and increased laboratory parameters of systemic inflammation (ferritin 308 mcg/L, C-reactive protein (CRP) 244 mg/L)...

AIM: To analyze therapeutic changes in Crohn's disease (CD) patients following video capsule endoscopy (VCE) and to assess the usefulness of Lewis score and the Patency Capsule. METHODS: Patency Capsule was performed in every patient that had indication for VCE, and those with negative patency did not undergo VCE. Patients with established CD that underwent VCE between January 2011 and February 2014 were selected for this study; those with suspected CD were excluded, independent of VCE results, since our purpose was to address differences in therapeutic regimen in CD patients before and after VCE...

BACKGROUND AND AIMS: There are contradictory findings regarding long-term outcome in patients with obscure gastrointestinal bleeding and negative capsule endoscopy. Factors associated with rebleeding after a negative videocapsule are not entirely known. OBJECTIVE: The aim of this study was to compare the rebleeding rate between negative and positive capsule endoscopy patients and to identify predictive factors for rebleeding in patients with negative findings. MATERIAL AND METHODS: Consecutive patients with obscure gastrointestinal bleeding referred to a single center over a period of 5 years were identified...

Because the ileocecal valve could theoretically influence the progression of the videocapsule, we aimed to characterize its posed delay in videocapsule passage to the cecum. A retrospective study was conducted of all procedures in which patients experienced in the same day colonoscopy with ileal biopsy and videocapsule endoscopy. In all 11 patients who satisfied the criteria, at least one biopsy-induced ileal mucosal defect could be identified. There was a mean delay in the passage of the videocapsule through the ileocecal valve of more than 43 minutes (range: 9 seconds to 143 minutes)...

Present case report refers to a 48-year-old man with genetic haemochromatosis (C282Y mut/mut) diagnosed at the age of 26. After aggressive iron depleting regimen carried out up to normalization of iron-related indexes, he received a maintenance regimen based on regular phlebotomies for about 20 years. In 2014, a marked reduction of both serum ferritin and transferrin saturation percent, without concomitant anaemia, was noted on two different occasions at 5-month interval. An obscure occult GI bleeding was suspected, but both upper and lower GI tract endoscopy were negative for abnormal findings, as also was a detailed abdominal US scan...

Currently, standard endoscopy is not considered enough reliable for the evaluation of celiac disease, neither to drive biopsy sampling. The diagnostic reliability of the endoscopic assessment of celiac disease has been increased by the recent advancement of software and hardware technologies. Several endoscopic technologies have been investigated so far for the diagnostic evaluation of celiac disease, including: water-immersion techniques, dye-based and dye-less chromoendoscopy techniques (Narrow band imaging; Fujinon Intelligeng Chromo Endoscopy; I-scan); optical coherence tomography; confocal laser endomicroscopy; high-resolution magnification endoscopy; videocapsule endoscopy; enteroscopy...

BACKGROUND: Because of its technical characteristics (i.e. 8-fold magnification, capability to inspect the entire small bowel) and minimal invasiveness, videocapsule endoscopy (VCE) has been proposed as a useful tool for managing patients with celiac disease (CD). KEY MESSAGES: Although VCE has been found to be highly sensitive and specific in identifying CD endoscopic markers, it is still inadequate to replace esophagogastroduodenoscopy (EGD) with biopsies in the diagnosis of CD...

INTRODUCTION: The levels of calprotectin in the stools are proportional to neutrophil activity in the enteric lumen, so fecal calprotectin is a useful intestinal inflammatory biomarker. It is an extended tool as predictor of colonic pathology but there is scare evidence about its utility in the small bowel. OBJECTIVE: To test the yield of fecal calprotectin to detect lesions in the small bowel. MATERIAL AND METHODS: We have retrospectively included 71 patients sent for small bowel capsule endoscopy in study for suspected inflammatory bowel disease...
