Takahisa Yamasaki, Jessica O'Neil, Ronnie Fass
The definition of functional heartburn has been refined over the years. It is currently described, based upon Rome IV criteria, as typical heartburn symptoms in the presence of normal upper endoscopy findings (including normal biopsies), normal esophageal pH testing, and a negative association between symptoms and reflux events. Functional heartburn is very common, affecting women more than men, and with reflux hypersensitivity makes up the majority of heartburn patients who fail twice-daily proton pump inhibitor therapy...

REVIEW
Sarmed S Sami, Prasad G Iyer
OPINION STATEMENT: PURPOSE OF REVIEW: There is a pressing need for effective strategies to halt the increase in both the incidence and mortality of esophageal adenocarcinoma (EAC). Screening for Barrett's esophagus, which is the only known precursor of EAC, remains a ripe area for research, particularly with regard to identifying the target population, screening tools, and management of screen-detected populations. This review aims to explore in depth the rationale for screening for Barrett's esophagus, recent biotechnological advances which may have the potential of making screening feasible, and also highlight the challenges which will have to be overcome in order make screening for BE a realistic prospect...

Small intestinal tumors are rare with adenocarcinoma of the small intestine accounting for less than 2% of all gastrointestinal cancers. Primary jejunal adenocarcinoma constitutes a minute portion of small intestine adenocarcinomas. Clinically, this cancer presents at latter stages of its progression, mainly due to vague and non-specific symptoms, and the difficulty encountered in accessing the jejunum on upper endoscopy. Diagnosis of jejunal adenocarcinoma is usually inconclusive with the use of computed tomography (CT) scan, small bowel series, or upper endoscopy...

Background: Neuroendocine tumors (NETs) or carcinoids arise at many different sites of the gastrointestinal tract. The small intestine is the most common site for NETs. Diagnosing small bowel carcinoids remains challenging given their non-specific presentations and the overall low incidence of small bowel tumors. Video capsule endoscopy (VCE) has significanly improved our ability to detect small bowel malignancies. We explore the value of VCE in the initial workup and management of a series of small bowel carcinoid patients...

BACKGROUND: During capsule endoscopy (CE) studies, the complete examination rate (CER) can be increased by prolonging capsule battery life or reducing gastric transit time (GTT) and/or small bowel transit time (SBTT). However, despite enhanced battery life, 10% of studies remain incomplete. Previously studied interventions to reduce SBTT and enhance CER have produced conflicting results. We hypothesize that this may be a consequence of an insufficiently potent stimulus of small bowel motility...

A reliable, real time localization functionality is crutial for actively controlled capsule endoscopy robots, which are an emerging, minimally invasive diagnostic and therapeutic technology for the gastrointestinal (GI) tract. In this study, we extend the success of deep learning approaches from various research fields to the problem of sensor fusion for endoscopic capsule robots. We propose a multi-sensor fusion based localization approach which combines endoscopic camera information and magnetic sensor based localization information...

Since the development of capsule endoscopy technology, medical device companies and research groups have made significant progress to turn passive capsule endoscopes into robotic active capsule endoscopes. However, the use of robotic capsules in endoscopy still has some challenges. One such challenge is the precise localization of the actively controlled robot in real-time. In this paper, we propose a non-rigid map fusion based direct simultaneous localization and mapping method for endoscopic capsule robots...

INTRODUCTION: Capsule endoscopy (CE) has the highest sensitivity in the evaluation of small-bowel mucosa in Crohn's disease (CD). Recent guidelines recommend the use of validated CE scores to assess small-bowel inflammatory activity in CD. Lewis score (LS) and Capsule Endoscopy Crohn's Disease Activity Index (CECDAI) are the currently available validated scores, but comparative studies are scarce. Moreover, correlation of these endoscopic scores with biomarkers and clinical activity is lacking...

AIM: Small bowel capsule endoscopy (CE) is a non-invasive and validated technique allowing the visualization of the small intestine mucosa. It generated more than 40,000 images per examination and induced a long median time of medical reading that may exceed 1 hour. In a transfer of skills' program, the CE reading might be transferred to nurses. We herein evaluate and present a feasibility study of the CE to nurses. METHODS: Nurses experienced in endoscopy were trained for small bowel CE reading, selection and interpretation of pathological images...

Introduction: Increasing demands on healthcare systems mean that nurses are taking on more roles as physician extenders. Capsule endoscopy (CE) is a laborious procedure where specialist nurses could reduce physician workload and rationalise resource utilisation. The aim of this review and meta-analysis is to consolidate data on nurses' performance in small bowel CE (SBCE). Materials and methods: A comprehensive literature search was conducted for randomised controlled trials and comparative studies on nurses in SBCE reading compared to physicians...

BACKGROUND: Among patients with obscure gastrointestinal bleeding (OGIB), endoscopic ulcerative lesions in the small bowel have diverse etiologies and often cause rebleeding. Certain characteristics of patients or ulcerations may be reasonable indications for diagnostic balloon-assisted endoscopy (BAE) to assess etiology and may be risks of rebleeding; however, these characteristics are unclear. We aimed to elucidate appropriate indications for diagnostic BAE and predictors of long-term rebleeding in patients with small-bowel ulcerative lesions...

Background and Aims: Balloon-assisted enteroscopy (BAE) is a well-established tool in the diagnosis and therapy of small bowel diseases. Ink tattooing of the small bowel is used to mark pathologic lesions or the depth of small bowel insertion. The purpose of this study was to determine the safety, the detection rate, and the clinical relevance of ink tattooing during BAE. Methods: We performed a retrospective analysis of all 81 patients who received an ink tattooing during BAE between 2010 and 2015...

This paper proposes an advanced method for contrast enhancement of capsule endoscopic images, with the main objective to obtain sufficient information about the vessels and structures in more distant (or darker) parts of capsule endoscopic images. The proposed method (PM) combines two algorithms for the enhancement of darker and brighter areas of capsule endoscopic images, respectively. The half-unit weighted-bilinear algorithm (HWB) proposed in our previous work is used to enhance darker areas according to the darker map content of its HSV's component V...

PURPOSE: Domperidone is thought to accelerate gastric emptying via D2 receptor antagonism at the gastro-oesophageal and gastro-duodenal junctions. Listed in the BNF as a prokinetic anti-emetic, it has been used in video capsule endoscopy (VCE) to accelerate capsule delivery to the small intestine. We audited VCEs performed at UHCW from 2011, when as standard practice, domperidone was given pre-VCE, to 2012, after its discontinuation due to doubts about its effectiveness. METHODS: Thirty-one patients received oral domperidone 20 mg pre-VCE...

This pilot study assessed wireless capsule endoscopy in horses. Image transmission was achieved with good image quality. Time to exit the stomach was variable and identified as one limitation, together with gaps in image transmission, capsule tumbling, and inability to accurately locate the capsule. Findings demonstrate usefulness and current limitations.
