What's new in capsule endoscopy?

Background: The faecal immunochemical test (FIT) is an immunoassay used to detect human blood in the stool. The role of FIT as a screening tool for small bowel pathology remains unclear.
Objectives: This study aimed to investigate the role of FIT in predicting small bowel pathology in patients with iron deficiency anaemia (IDA).

A 65-year-old man with a history of chronic renal failure and ischemic heart disease who was receiving aspirin therapy was admitted for recurrent melena. Initial evaluation revealed severe anemia. Other than a diverticulum in the third part of the duodenum, the findings of upper and lower gastrointestinal endoscopies and computed tomography were unremarkable.

A 61-year-old woman who had been taking olmesartan for 7 years complained of epigastric pain, diarrhea, loss of appetite, and weight loss. Esophagogastroduodenoscopy revealed roughened mucosa and erosions in the stomach and duodenum.

Neuroendocrine tumours (NETs) are relatively rare neoplasms but represent one of the most frequent types of primary small-bowel tumours.

Current wireless capsule endoscopy (WCE) is limited in the long examination time and low flexibility since the capsule is passively moved by the natural peristalsis. Efforts have been made to facilitate the active locomotion of WCE using magnetic actuation and localization technologies.

Meckel's diverticulum, the most common congenital anomaly of the gastrointestinal tract, is often asymptomatic. Lack of complete resorption of the omphalomesenteric duct is an important cause of Meckel's diverticulum. Gastrointestinal (GI) bleeding is a major complication of Meckel's diverticulum.

Video capsule endoscopy has become the gold standard for the evaluation of small bowel pathology. Capsular retention remains the most significant risk of this intervention.

Background and aim: We aimed to develop and validate a simple capsule endoscopy (CE) training assessment tool, the Capsule Endoscopy Training Assessment (CETA), and prospectively use it to analyze the learning progression achieved by participants in our CE training program.

Background: Fewer studies have been conducted on the diagnostic value of capsule endoscopy, CT enterography and enteroscopy in suspected small bowel bleeding. This study aimed at analyzing the diagnostic and clinical value of capsule endoscopy, CT enterography and enteroscopy for suspected small bowel bleeding.

Background: A Dieulafoy's lesion in the jejunum is at an uncommon site but may be the cause of massive gastrointestinal bleeding. It is characterized by a large, tortuous submucosal artery that erodes the overlying epithelium and presents diagnostic and therapeutic challenges due to its atypical location and presentation.

A 79-year-old man with fatigue and melena was diagnosed with severe iron-deficiency anemia.

The diagnosis and management of small bowel bleeding (SBB) can be a clinical challenge. Advances in video capsule endoscopy, balloon-assisted enteroscopy, and multiphasic computed tomography allow for localization and therapeutic intervention.

Introduction Diagnostics of small bowel Crohn's disease (CD) can be difficult. Combined positron emission tomography-magnetic resonance enterography (PET-MRE) can be used to evaluate intestinal metabolism, but clinical use has been limited due to accessibility, costs, absence of standardized methods and diagnostic thresholds.

Introduction: The PillCam™ patency capsule is useful in preventing capsule endoscope retention; however, visual confirmation of patency capsule excretion is challenging for many patients.

Background: Although capsule endoscopy (CE) is a crucial tool for diagnosing small bowel diseases, the need to process a vast number of images imposes a significant workload on physicians, leading to a high risk of missed diagnoses.

Objectives: We report disease outcomes of pediatric Crohn's disease (CD) affecting the proximal small bowel (SB) and detected through video capsule endoscopy (VCE).

Background: Patency capsule (PC) ingestion is commonly used to minimize capsule retention in high-risk patients with Crohn's disease (CD). However, false-positive rates remain high, precluding the use of video capsule endoscopy (VCE).

Introductionand importance:Gastrointestinal stromal tumors (GISTs) are raremesenchymal tumors, constituting 1 % of gastrointestinal tumors. Jejunal GISTsare even rarer.

The diagnosis and management of small bowel bleeding (SBB) can be a clinical challenge. Advances in video capsule endoscopy, balloon-assisted enteroscopy, and multiphasic computed tomography allow for localization and therapeutic intervention.

Background: Heyde syndrome is characterized by anemia due to angiodysplasia, aortic valve stenosis, and acquired von Willebrand syndrome. However, the awareness regarding Heyde syndrome in clinical practice is low. We report the case of an older woman with severe refractory iron-deficiency anemia and severe aortic stenosis who was diagnosed with Heyde syndrome.

Background and objectives: EUS is an important modality for diagnosis and assessment of gastrointestinal (GI) subepithelial lesions. However, EUS is invasive and operator-dependent and requires sedation in most cases. The newly developed ultrasound capsule endoscopy (USCE) system, with both white-light and ultrasound imaging modalities, is a minimally invasive method for superficial and submucosal imaging of the esophagus.

Obscure gastrointestinal bleeding (OGIB), defined in 2010, involves bleeding from the GI tract that remains unexplained after standard diagnostic procedures. OGIB, which accounts for about 5% of all GI bleeds, poses diagnostic and management challenges, particularly due to the anatomical features of the small intestine.

Objective: The purpose was to investigate the risk factors for delayed upper gastrointestinal transit (DUGT) in small bowel capsule endoscopy (SBCE) and to improve the efficacy of SBCE.

Herein, we describe a case of olmesartan-associated sprue-like enteropathy, in which improvement in villous atrophy was confirmed using small bowel capsule endoscopy.

Background: Methanogens are associated with gut dysmotility in animal models but have not been robustly studied in humans. The WMC assesses regional transit time (TT) and pH in the GI tract. Aims: To study the segmental TT and pH among patients with SIBO or IMO utilizing WMC.

Background: Evaluation of gut motility in clinical practice is currently limited. A novel medical system (MoPill™) consisting of a capsule that wirelessly transmits radiofrequency signals to assess motility via 3D location, was used to conduct this study.

Objectives: To compare the recently proposed Capsule Endoscopy-Crohn's Disease index (CE-CD) to pre-existing capsule endoscopy (CE) scores, to measure its precision and accuracy to predict adverse clinical outcomes in children with Crohn's disease (CD).

Background: The role of capsule endoscopy in the evaluation of the small bowel is well established, and current guidelines position it as a first-line test in a variety of clinical scenarios. The advent of double-headed capsules further enabled the endoscopic assessment of colonic mucosa and the opportunity for a one-step noninvasive examination of the entire bowel (pan-enteric capsule endoscopy [PCE]).
