Abstract
Introduction This study aimed to assess the effectiveness of capsule endoscopy in detecting gastric foreign bodies in normal dogs, considering variations in the number of foreign bodies and the gastric environment. Methods Five healthy male beagles were administered virtual, non-harmful foreign objects that maintained their shape in the stomach. Capsule endoscopy was performed and the images were evaluated by veterinarians and non-veterinarians. Results The overall sensitivity and specificity of capsule endoscopy were 99.1 and 90.4%, respectively. Sensitivity and specificity were comparable between veterinarians and non-veterinarians. Sensitivity and specificity in the veterinarian group were 98.7 and 91.2%, respectively, whereas those in the non-veterinarian group were 100 and 88.5%, respectively. Discussion Capsule endoscopy is a valuable alternative diagnostic tool for identifying foreign bodies in the stomach, particularly in challenging cases in which conventional imaging or invasive approaches have limitations.

Abstract
BACKGROUND PURPOSE Capsule endoscopy (CE) is a noninvasive examination for excellent visualization of small bowel mucosal lesions. We aimed to evaluate the clinical efficacy and safety of CE in pediatric patients. METHODS From April 2014 to December 2022, CE procedures performed in children younger than 18 years of age at Taichung Veteran General Hospital were analyzed retrospectively. RESULTS Among 136 procedures, the completion rate was 95.6% (n = 130), with a median age of 14 years old. Suspicion or evaluation of inflammatory bowel diseases (IBD) (41%) was the most common indication for CE. Other common indications of CE were chronic unexplained abdominal pain (35%) and obscure gastrointestinal bleeding or iron deficiency anemia (21%). No procedure-related complications occurred. The diagnosis of those patients with incomplete study were CD with small bowel stricture, graft-versus-host disease and duodenal ulcers. A total of 86 CE procedures showed positive findings, and the overall diagnostic yield rate was 63.2%. Small bowel ulcers (65.12%) were the most common findings. Overall, 26.5% of CE examinations resulted in a new diagnosis and 44.9% of CE exams led to a change in therapy. For patients with IBD, CE findings resulted in an even higher therapeutic change rate of 48.1%. CONCLUSIONS CE is a safe and feasible diagnostic method to study the small intestine in children, especially for IBD. Incomplete study could be an indicator of positive finding and can potentially be a guide to identify the site of possible strictures.

Abstract
Small bowel evaluation has been transformed by capsule endoscopy and advances in small bowel imaging, which provide reliable and noninvasive means for assessing the mucosal surface. Device-assisted enteroscopy has been critical for histopathological confirmation and endoscopic therapy for a wide range of small bowel pathology that conventional endoscopy cannot reach. The purpose of this review is to provide a comprehensive overview of the indications, techniques, and clinical applications of capsule endoscopy; device-assisted enteroscopy; and imaging studies for small bowel evaluation in children.

Abstract
Disease phenotype of pediatric inflammatory bowel disease (PIBD) in children from the Asia-Pacific region differs from that of children from the West. Many parts of Asia are endemic for tuberculosis, making diagnosis and management of pediatric Crohn's disease a challenge. Current available guidelines, mainly from Europe and North America, may not be completely applicable to clinicians caring for children with PIBD in Asia due to differences in disease characteristics and regional resource constraints. This position paper is an initiative from the Asian Pan-Pacific Society for Pediatric Gastroenterology, Hepatology and Nutrition (APPSPGHAN) that aims to provide an up-to-date, evidence-based approach to PIBD in the Asia-Pacific region. A group of pediatric gastroenterologists with a special interest in PIBD performed an extensive literature search covering epidemiology, disease characteristics and natural history, management, and monitoring. Attention was paid to publications from the region with special consideration to a resource-limited setting. This current position paper deals with surgical management, disease monitoring, immunization, bone health, and nutritional issues of PIBD in Asia. A special section on differentiating pediatric Crohn's disease from tuberculosis in children is included. This position paper provides a useful guide to clinicians in the surgical management, disease monitoring, and various health issues in children with IBD in Asia-Pacific region.

Abstract
Fecal calprotectin (FC) has been proposed as a noninvasive surrogate marker of intestinal inflammation in inflammatory bowel disease. This study aimed to assess the capability of FC in predicting small bowel capsule endoscopy (SBCE) findings in pediatric patients with known Crohn's disease (CD). We retrieved data of consecutive patients aged 2 to 17 years old with established CD who underwent SBCE from Janurary 2017 to April 2020 and had endoscopic remission on ileocolonoscopy. Sixty-eight patients were included in the analysis. There were 13 patients with a weighted pediatric CD activity index ≥ 12.5, 47 patients with FC ≥ 200 µg/g, and 45 patients with significant small bowel (SB) inflammation [Lewis score (LS) ≥ 135]. The LS correlated weakly with FC (R = 0.30, P < .05). The area under the curve of FC as a surrogate diagnostic test for LS ≥ 135 was 0.691, and the optimal FC cutoff values were 242 µg/g with the corresponding sensitivity and specificity of 78% and 65%, respectively. The area under the curve of FC for moderate-to-severe inflammatory activity in the SB was 0.718. In patients with FC level ≥ 670 µg/g, LS ≥ 790 was found in 33% (9/27) of patients, with the sensitivity and specificity of 69% and 67%, respectively. FC may be used to predict SB mucosal inflammation in pediatric patients with confirmed CD having endoscopic remission on ileocolonoscopy.

Abstract
Video capsule endoscopy (VCE) is a noninvasive modality to broadly image the gastrointestinal tract. Previously, the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition and its endoscopy committee noted a lack of standardized pediatric VCE training. It was hypothesized that a web-based curriculum could be broadly implemented and help to enhance comfort and develop VCE skills. Methods A pilot web-based VCE curriculum was created using REDCap database. An email invitation asking for participation was sent to a pediatric gastroenterology Listserv. Baseline comfort and knowledge regarding VCE skills were measured. Educational links and materials were provided following which participants completed VCE cases with immediate feedback. Finally, participants completed a posttest and a survey to complete the curriculum. Results Fifty-two participants began the curriculum of which 37 (71%) partially completed, 12 (23%) completed, and 3 (6%) withdrew. Significant improvement was noted regarding self-reported mean comfort level in explaining indications (P = 0.0097), contraindications (P = 0.0036), managing complications (P = 0.0048), using VCE software (P = 0.00035), and interpreting VCE findings (P = 0.00015). Participants showed significant improvement in knowledge (P = 0.041) and photo recognition posttests (P = 0.015). All participants who completed the curriculum found it helpful and reported that they would recommend it to their colleagues. Conclusions This pilot curriculum demonstrated an improvement in participant self-reported comfort and an increase in VCE knowledge. Further resources would make a web-based curriculum easier to navigate and complete. Providing Continuation of Medical Education and Maintenance of Certification credits for future curricular iterations would provide an opportunity for training with recognition for pediatric gastroenterologists.

Abstract
BACKGROUND The complete examination rate of video capsule endoscopy can be increased by reduced gastric transit time (GTT) and or small bowel transit time (SBTT). This study aims to examine whether the prokinetic domperidone reduces GTT and/or SBTT in pediatric patients undergoing video capsule endoscopy (VCE). METHODS We performed a single-center randomized controlled trial (n=200) to evaluate the effect of domperidone on GTT and SBTT among pediatric patients in a tertiary university-affiliated hospital for children. We explored whether patients randomized to domperidone had increased GTT, SBTT (primary outcomes) or higher complete examination rate (secondary outcome). The safety outcomes were the adverse effects in the domperidone group. This study was registered on ClinicalTrials.gov (NCT03662113). RESULTS Demographic features including gender and age were similar between the 100 patients of the domperidone group and the 100 patients of the control group. The median GTT was 67.5 minutes (44.8-117.5) in the domperidone group and 80.0 minutes (42.0-128.0) in the control group, while the median SBTT was 317 minutes (231-436) and 323 minutes (225-426), respectively. There were no significant differences in GTT (P=0.49) and SBTT (P=0.52) between the two groups. The complete examination rate was 97% and 98% in the domperidone and control groups, respectively (P=1.00). CONCLUSIONS Domperidone shows no effect on GTT, SBTT and complete examination rate in pediatric patients receiving VCE.

Abstract
Background and Aim: Melena, or tarry black stool, is not a rare symptom encountered in pediatric clinical practice, and the bleeding source varies from the upper gastrointestinal tract to the small intestine. Endoscopy is effective in identifying bleeding, but it does not always identify the source of bleeding. Endoscopic examination in children is commonly challenging, and there are no detailed reports about the causes of melena in children. This observational study aimed to validate the cause of melena in children and to investigate more effective and less burdensome examination methods. Methods: We retrospectively reviewed the clinical records of 55 patients who underwent examination for melena. Results: In this research, 38 patients had underlying diseases such as malignancy and severe mental and physical disorders. The bleeding source was identified in 39 patients. The most common final diagnosis was duodenal ulcer (n = 22), and the other diagnoses were gastric ulcer, esophagitis, and esophageal varices. The upper gastrointestinal tract was the most common source of bleeding (n = 34). In five patients, the bleeding source was the small intestine. Vomiting, abnormal abdominal ultrasonography findings, and a hemoglobin level of ≤ 3 g/dL than the lower normal limit were significant factors indicating that the bleeding source can be found on esophagogastroduodenoscopy. Conclusions: The upper gastrointestinal tract was the most common bleeding source of melena in children. As in adults, esophagogastroduodenoscopy is the primary endoscopic method of choice. Furthermore, small bowel capsule endoscopy may be useful in identifying the bleeding source in children without upper gastrointestinal lesions.

Abstract
Video capsule endoscopy (VCE) can detect mucosal lesions in the intestine, especially in the small bowel.Our study aims to evaluate the applications of VCE for pediatric gastrointestinal diseases.In this retrospective study, we included all patients who underwent VCE between December 2012 and December 2018. Clinical information and VCE data were analyzed.Among 828 patients, the completion rate was 99.6% (n = 825), with an average age of 10.2 ± 3.3 years old. A total of 459 VCE procedures showed abnormalities, and the overall diagnostic yield was 55.6%. The most common indications for VCE were abdominal pain among 505 (61.2%) patients and hematochezia (10.1%) among 83. Among the positive results of VCE, small bowel ulcers accounted for the highest percentage (57.7%), of which 164 cases were diagnosed as inflammatory bowel disease. For obscure gastrointestinal bleeding, 12 cases were diagnosed as Meckel's diverticulum. In terms of the small bowel transit time of VCE, compared with the negative group [288 (216.5, 390.3) min] and the enteritis group [277 (192.5, 374.8) min], a longer transit time was needed in the small bowel ulcer group [332.5 (240, 451.5) min, P < .01]. There were no correlations of positive VCE findings with anemia, the white blood cell count, the C-reactive protein level or the small bowel transit time according to Spearman rank analysis.VCE is relatively well tolerated and safe in children and has great value for the diagnosis and treatment of abdominal pain, especially inflammatory bowel disease and obscure gastrointestinal bleeding.

Abstract
BACKGROUND Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract and is also an important cause of bloody stool and anemia in children. However, there are few data about video capsule endoscopy (VCE) for MD in children. This study aimed to evaluate the diagnostic value of VCE for MD in children. MATERIALS AND METHODS children who underwent VCE for obscure gastrointestinal bleeding from October 1st 2015 to August 31st 2019 at the Children's Hospital of Fudan University were included in this retrospective study. Medical data, VCE data and Meckel's scans, etc. were collected for each patient. RESULTS sixteen patients were diagnosed with MD by VCE, including 13 males and 3 females. The age of the patients ranged from 4 years to 13 years, with an average of 7.8 ± 2.7 years. Lower gastrointestinal tract bleeding was the main symptom for patients with MD, including hematochezia (75 %) and melena (25 %). Of the VCE findings, 14 patients had double lumen signs and 2 showed protruding lesions. Among the 16 patients diagnosed with MD by VCE, 14 patients were diagnosed with MD by Meckel's scan, 3 with MD by abdominal enhanced CT and 14 patients were diagnosed with MD by surgery. During the follow-up, bleeding occurred sporadically in patient 12 and the reason is still unknown. CONCLUSIONS VCE is useful for the diagnosis of MD and should be used as a valuable and less invasive examination to confirm or establish a diagnosis.

Abstract
OBJECTIVES This multicenter, cross-sectional study aimed to elucidate the efficacy and safety of the AdvanCE capsule endoscope delivery device for children in Japan. METHODS The present study analyzed 183 cases of small bowel capsule endoscope (SBCE) insertion performed using the AdvanCE in 154 patients aged less than 18 years at participating institutions between 2013 and 2017. Statistical analyses were conducted to identify factors contributing to the completion rate for the entire small intestine examination, small intestine transit time, adverse events and technical issues. RESULTS The commonest reason for using the AdvanCE was the patient's inability to swallow the SBCE, which was attributed to young age. SBCE was successfully delivered into the stomach or duodenum in 180 cases and was placed in the duodenum in 90% patients. In 89% patients, the entire small intestine was completely examined, and in 63% patients, findings leading to a new diagnosis or involving changing or maintaining the treatment strategy were obtained. No severe adverse events were observed; however, mild adverse events were observed in 35% patients. No factors considerably contributed to the completion rate for the entire small intestine examination or small intestine transit time and onset of technical issues. The factors that contributed to mild adverse events included intravenous anesthesia, technical issue, and absence of prior insertion of a patency capsule using the AdvanCE. CONCLUSION The AdvanCE is well tolerated and effective for children.

ASGE EndoVators Summit: simulators and the future of endoscopic training. Gastrointest Endosc 2019; 90:13-26. [PMID: 31122744 DOI: 10.1016/j.gie.2018.10.031] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2018] [Accepted: 10/24/2018] [Indexed: 02/07/2023]
Abstract
Interest in the use of simulation for acquiring, maintaining, and assessing skills in GI endoscopy has grown over the past decade, as evidenced by recent American Society for Gastrointestinal Endoscopy (ASGE) guidelines encouraging the use of endoscopy simulation training and its incorporation into training standards by a key accreditation organization. An EndoVators Summit, partially supported by a grant from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health, (NIH) was held at the ASGE Institute for Training and Technology from November 19 to 20, 2017. The summit brought together over 70 thought leaders in simulation research and simulator development and key decision makers from industry. Proceedings opened with a historical review of the role of simulation in medicine and an outline of priority areas related to the emerging role of simulation training within medicine broadly. Subsequent sessions addressed the summit's purposes: to review the current state of endoscopy simulation and the role it could play in endoscopic training, to define the role and value of simulators in the future of endoscopic training and to reach consensus regarding priority areas for simulation-related education and research and simulator development. This white paper provides an overview of the central points raised by presenters, synthesizes the discussions on the key issues under consideration, and outlines actionable items and/or areas of consensus reached by summit participants and society leadership pertinent to each session. The goal was to provide a working roadmap for the developers of simulators, the investigators who strive to define the optimal use of endoscopy-related simulation and assess its impact on educational outcomes and health care quality, and the educators who seek to enhance integration of simulation into training and practice.

Abstract
Peutz-Jeghers syndrome (PJS) is a well-described inherited syndrome, characterized by the development of gastrointestinal polyps, and characteristic mucocutaneous freckling. Development of small bowel intestinal polyps may lead to intussusception in children may require emergency laparotomy with potential loss of bowel. Gastrointestinal polyps may lead to bleeding and anemia. This European Society for Paediatric Gastroenterology Hepatology and Nutrition position paper provides a guide for diagnosis, assessment, and management of PJS in children and adolescents and guidance on avoiding complications from PJS or from the endoscopic procedures performed on these patients.This is the first position paper regarding PJS published by European Society for Paediatric Gastroenterology Hepatology and Nutrition. Literature from PubMed, Medline, and Embase was reviewed and in the absence of evidence, recommendations reflect the opinion of pediatric and adult experts involved in the care of polyposis syndromes. Because many of the studies that form the basis for the recommendations were descriptive and/or retrospective in nature, some of the recommendations are based on expert opinion. This position paper will be helpful in the appropriate management and timing of procedures in children and adolescents with PJS.

Abstract
Background: The small bowel has often been considered the mysterious “black hole” of the gastrointestinal tract. With regards to this, the development of the wireless capsule endoscopy (WCE) has represented a turning point. It is a non-invasive technique, enabling an excellent visualization of the small bowel (SB) mucosa without the use of radiation. The WCE was approved by the Food and Drug Administration (FDA) in 2001 for adults and in 2004 for children. The aim of the present review is to provide an update on indications, diagnostic yield, safety and limitations of WCE in children. Even though literature regarding the use of WCE in pediatric age is more limited than in adults,WCE is a useful and safe diagnostic tool for the exploration of the small bowel also in children. The indications for WCE are similar at any age, however the main indication in children is Crohn’s disease (CD), while in the adults is the research of SB bleeding. The main limitation in pediatric age is the possibility for younger children to swallow the capsule. WCE in pediatric is a rapidly advancing technology and has the potential to further transform the evaluation and management of SB disease. (www.actabiomedica.it)

Abstract
Endoscopy is a central tool for the evaluation and management of inflammatory bowel disease (IBD). In the last few decades, gastrointestinal (GI) endoscopy has undergone significant technological developments including availability of pediatric-size equipment, enabling comprehensive investigation of the GI tract in children. Simultaneously, professional organization of GI experts have developed guidelines and training programs in pediatric GI endoscopy. This prompted the Porto Group on Pediatric IBD of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition to develop updated guidelines on the role of GI endoscopy in pediatric IBD, specifically taking into considerations of recent advances in the diagnosis, disease stratification, and novel therapeutic targets in these patients.

Abstract
BACKGROUND Video capsule endoscopy (VCE) is a noninvasive method enabling excellent visualization of the small bowel (SB) mucosa. The aim of this study was to examine the impact and safety of VCE performed in children and adolescents with suspected or established Crohn's disease (CD). METHODS A total of 180 VCE examinations in 169 consecutive patients conducted in 2003-14 in a single center were retrospectively analyzed. The median age was 13 years (range 3-17 years) and indications for VCE were suspected (125 cases, 69%) and established (55 cases, 31%) CD. VCE was performed with a PillCam SB (Given Imaging, Yokneam, Israel) VCE system with 8-12 h of registration without bowel preparation. RESULTS A total of 154 of 180 (86%) patients swallowed the capsule and 26 (14%) had the capsule endoscopically placed in the duodenum. Patency capsule examination was performed in 71 cases prior to VCE to exclude SB obstruction. VCE detected findings consistent with SB CD in 71 (40%) examinations and 17 (9%) procedures showed minor changes not diagnostic for CD. A total of 92 (51%) examinations displayed normal SB mucosa. The capsule did not reach the colon within the recording time in 30 (17%) procedures and were defined as incomplete examinations. A change in diagnosis or therapy was recommended in 56 (31%) patients based on VCE results. Capsule retention occurred in one patient. CONCLUSIONS VCE is a safe method in children with suspected or established CD. VCE often leads to a definitive diagnosis and has a significant impact on the clinical management of pediatric patients with CD.

Abstract
AIM To assess the feasibility and safety of a novel enteroscope, negative-pressure suction endoscope in examining the small intestine of a porcine model.
METHODS In vitro experiments in small intestinal loops from 20 pigs and in vivo experiments in 20 living pigs were conducted.
RESULTS In in vitro experiments, a negative pressure of > 0.06 MPa was necessary for optimal visualization of the intestine, and this pressure did not cause gross or histological damage to the mucosa. For satisfactory examination of the small intestine in vivo, higher negative pressure (> 1.00 MPa) was required. Despite this higher pressure, the small intestine did not show any gross or microscopic damage in the suctioned areas. The average time of examination in the living animals was 60 ± 7.67 min. The animals did not experience any apparent ill effects from the procedure.
CONCLUSION Small intestine endoscope was safely performed within a reasonable time period and enabled complete visualization of the intestine in most cases.

Abstract
Capsule retention (CR) has been defined as capsule remaining in the digestive tract for a minimum of two weeks. CR occurs approximately in 2% of all patients undergoing small bowel capsule endoscopy (CE). Prompt diagnosis of CR is important, as it has relevant clinical implications. CR should be suspected in (I) all asymptomatic patients who do not report capsule excretion within 15 days from capsule ingestion; and (II) patients with obstructive or perforation-related symptoms in which the capsule has not been excreted, regardless of the time between the onset of symptoms and capsule ingestion. Abdominal plain X-ray is the preferred test to confirm CR. An abdominal CT scan should be performed, on individual basis, if knowledge of the precise location of the retained capsule is necessary or whenever clinically indicated. Since CR is usually asymptomatic, an initial watchful monitoring is suggested. In inflammatory bowel disease (IBD) patients, a short course of medical therapy may allow capsule excretion. Nevertheless, in long-term CR, some cases of capsule fragmentation, acute obstruction and perforation have been described. Therefore, retrieval of the retained capsule is recommended if asymptomatic CR lasts for long time. A safe capsule retrieval is usually performed by endoscopy, whereas surgery remains a viable alternative if the first is unsuccessful or when clinically indicated. Either Patency Capsule® (PC) or dedicated small bowel cross-sectional imaging techniques have been proposed to prevent CR. Both have pros and cons, but head-to-head comparative studies are lacking.
