Abstract
Effectiveness of limited available therapies for pediatric inflammatory bowel disease has reached stagnation. Previous non-invasive monitoring strategies have relied upon cumbersome tools to evaluate clinical symptoms and biochemical markers that do not reflect endoscopic activity or respond quickly to treatments. Novel, patient-centric, and highly accurate, monitoring strategies with a focus on intestinal ultrasound for a direct, precise monitoring of activity to achieve disease modification are now possible. Ultimately, research on the optimal tight control monitoring strategies, individualized to each pediatric inflammatory bowel disease patient, are in development and offer a hope to potential therapeutic ceiling breakthrough on the horizon.

Abstract
Gastrointestinal endoscopy has grown dramatically over the past century, and with subsequent improvements in technology and anaesthesia, it has become a safe and useful tool for evaluation of GI pathology in children. There are substantial differences between paediatric and adult endoscopy beyond size, including: age-related patho-physiology and the different spectrum of diseases in children. Literature on endoscopic procedures in children is sparse but significant. The present review aims at describing the current knowledges on paediatric endoscopy practice and highlights the main areas of differences between paediatric and adult practice.

Abstract
Inflammatory bowel disease (IBD) includes Crohn’s disease (CD), ulcerative colitis and unclassified entities. CD commonly involves the terminal ileum and colon but at the time of diagnosis it can be confined to the small bowel (SB) in about 30% of the patients, especially in the young ones. Management of isolated SB-CD can be challenging and objective evaluation of the SB mucosa is essential in differentiating CD from other enteropathies to achieve therapeutic decisions and to plan the follow-up. The introduction of cross-sectional imaging techniques and capsule endoscopy (CE) have significantly expanded the ability to diagnose SB diseases providing a non-invasive test for the visualization of the entire SB mucosa. The main CE limitations are the low specificity, the lack of therapeutic capabilities and the impossibility to take biopsies. Device assisted enteroscopy (DAE) enables histological confirmation when traditional endoscopy, capsule endoscopy and cross-sectional imaging are inconclusive and also allows therapeutic interventions such as balloon stricture dilation, intralesional steroid injection, capsule retrieval and more recently stent insertion. In the current review we will discuss technical aspect, indications and safety profile of DAE in children and adults with IBD.

A Treat to Target Strategy Using Panenteric Capsule Endoscopy in Pediatric Patients With Crohn's Disease. Clin Gastroenterol Hepatol 2019; 17:2060-2067.e1. [PMID: 30326301 DOI: 10.1016/j.cgh.2018.10.015] [Citation(s) in RCA: 29] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2018] [Revised: 09/23/2018] [Accepted: 10/09/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Pan-enteric capsule endoscopy (PCE) is effective for assessment of small intestinal and colonic Crohn's disease (CD) in pediatric patients. We aimed to determine whether PCE can be used to monitor mucosal healing and deep remission, in a treat to target strategy for pediatric patients with CD. METHODS We performed a prospective study of 48 children with a diagnosis of CD at a tertiary care pediatric gastroenterology unit; 46 patients were included in the final analysis. Biomarker, imaging, and PCE analyses were performed at baseline and after 24 and 52 weeks. Small bowel and colonic mucosal healing were defined by Lewis scores <135 and simple endoscopic score for CD ≤1, respectively. Clinical remission was defined as defined as a pediatric CD activity index score <10 and biomarker-based remission based on normal levels of biomarkers; deep remission was defined as a combination of clinical remission, biomarker-based remission, and mucosal healing. Treatments were adjusted based on findings from PCE (imaging was considered only for patients with negative findings from PCE). Therapies were introduced, optimized, switched, or combined at the discretion of treating clinicians. The primary outcome was the ability of PCE to assess mucosal healing and deep remission at 3 timepoints and to guide a treat to target strategy. RESULTS PCE detected inflammation in 34 patients (71%) at baseline, 22 patients (46%) at week 24, and 18 patients (39%) at week 52 (P for comparison among timepoints <.05). Findings from PCE led to a change in therapy for 34 patients (71%) at baseline and 11 patients (23%) at 24 weeks, whereas only 2 patients with negative results from PCE (4%) changed therapies based on findings from imaging. When the treat to target strategy was applied, proportions of patients with mucosal healing and deep remission increased from 21% at baseline, to 54% at week 24, to 58% at week 52 (P for comparison among timepoints <.05); 2 patients (4%) did not respond to treatment. CONCLUSION In a prospective study of 48 children with CD, we found a treat to target strategy, based on findings from PCE, to significantly increase the proportions of patients with mucosal healing and deep remission.

World J Gastroenterol 2019; 25:3808-3822. [PMID: 31391775 PMCID: PMC6676548 DOI: 10.3748/wjg.v25.i28.3808] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2019] [Revised: 05/04/2019] [Accepted: 07/05/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Magnetic resonance enterography (MRE) and wireless capsule endoscopy (WCE) are equally accepted modalities for noninvasive screening of small bowel involvement (SBI) in children with Crohn’s disease (CD) and indeterminate colitis (IC) albeit there is a paucity of data comparing the two and thereby guiding the clinician in selecting the ideal diagnostic approach. Therefore, the goal of this study is to provide additional evidence for capsule endoscopy role in the evaluation of established Crohn’s disease exacerbation compared to MRE in relation to Pediatric Crohn's Disease Activity Index (PCDAI), and histological indices.
AIM To prospectively compare the findings of MRE and WCE and their agreement with PCDAI or histology in children with CD or IC.
METHODS Consecutive patients diagnosed with CD and IC were screened for inclusion. After informed consent, patient’s demographic and clinical data was abstracted. The current pediatric disease activity index (PCDAI) and endoscopic findings were included. Patients underwent MRE and WCE including preprocedural patency capsule within a maximum of 7 d of each other. Pathological presence of active small bowel disease in ileal and duodenal biopsies were collected if the endoscopy was performed within 2 mo of the WCE study. Patients who failed to pass the PC were excluded from the study. WCE was read by two different experienced gastroenterologists (Attard TM and Colombo JM) blinded to each other's findings and to the findings on MRE (Mardis NJ). Agreement between WCE reviewers, WCE and MRE findings and concordance between positive PCDAI and SBI based on MRE compared with WCE was computed.
RESULTS Forty-five patients were included in the study, 18 withdrew and 27 (20 males and 20 CD), mean age (standard deviation) 13.46 (2.4) years, completed the study protocol. There were no instances of capsule retention. Concordance between gastroenterologist reviewers was excellent for the diagnosis of small intestinal CD with good correlation between the two Lewis scores (r = 0.875, P < 0.001). Concordance between WCE and MRE was poor (69%). In CD patients, when both MRE and WCE were compared using PCDAI > 10 as the standard reference reflecting active small intestinal CD, the sensitivity of MRE and WCE were 100% and 83% respectively and the specificity of MRE and WCE were 57.14% and 78.6%, respectively. If the histology in ileum or/and duodenum was used as the reference for active small bowel involvement, WCE had a higher specificity as compared to MRE (83.3% vs 50%). In patients with Crohn’s disease, those with a positive PCDAI (> 10) were more likely to have a positive WCE as compared to those with a negative PCDAI (83% vs 21%; P = 0.018).
CONCLUSION We suggest that MRE and WCE have a complementary role in the assessment of SBI in CD. WCE detected SBI with a much higher specificity while MRE had a higher sensitivity.

Abstract
PURPOSE Pediatric Crohn's disease (CD) is directly related to growth and has a high probability of requiring surgical intervention(s); therefore, more active treatment for CD is required for children. This study investigated the impact of biologics on growth and disease course associated with surgery. METHODS This was a retrospective cohort study involving patients diagnosed with CD at the Seoul National University Children's Hospital (Seoul, Korea) between January 2006 and October 2017. The aim was to determine the characteristics of pediatric patients with CD and whether biologics affected growth and the surgical disease course. RESULTS Among patients who underwent surgery for CD, the mean number of operations per patient was 1.89. The mean time from initial diagnosis to surgery was 19.3 months. The most common procedure was fistulectomy (34%), followed by incision and drainage (25%). In all patients, the use of biologics increased the height (p=0.002) and body mass index (BMI) (p=0.005). Among patients who underwent surgery, height (p=0.004) and BMI (p=0.048) were increased in the group using biologics. Patients who used biologics exhibited a low operation rate only within 2 years after diagnosis, with no differences thereafter (p=0.027). CONCLUSION Although biologics could not mitigate the operation rate in pediatric patients who underwent surgery for CD, biological therapy delayed disease progression within 2 years of disease onset. Additionally, biologics conferred growth and BMI benefits in this window period. Therefore, it may be helpful to use biologics for optimal growth in pediatric patients with a high probability of undergoing future surgery.

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
OBJECTIVES Ileocolonoscopy (IC) and small bowel capsule endoscopy (SBCE) are essential tools in the investigation of suspected small bowel Crohn's disease (CD). Overutilization of SBCE should be avoided as it leads to unwanted healthcare expenses; thus, it is recommended when IC is normal and CD is still highly suspected. Our aim was to compare the role of SBCE and IC in the investigation of suspected CD irrespective of its location and assess the additional diagnostic benefit of SBCE over IC. METHODS This was a retrospective study of 91 patients with chronic abdominal pain and/or diarrhea. All patients were evaluated with both colonoscopy (with terminal ileum intubation where possible) and SBCE. The severity of inflammation on SBCE was assessed using the Lewis Score. Endoscopic findings were analyzed toward CD diagnosis. RESULTS The sensitivity of IC and SBCE in the diagnosis of either small bowel or colonic CD was 81.82 and 63.64%, whereas the specificity was 77.50 and 92.50%, respectively. Positive and negative predictive value was 33.33 and 96.88% for IC, as well as 53.85 and 94.87% for SBCE. Area under receiver operating characteristic curve was 0.797 for IC and 0.781 for SBCE. IC was superior to SBCE in diagnosing small and large bowel CD. SBCE showed the true extent of CD in one patient missed by IC. It identified lesions suggestive of CD in three patients with normal IC, one of whom was finally diagnosed with CD. CONCLUSION IC should be the initial diagnostic test in patients with nonspecific, but suggestive symptoms of CD. SBCE offers additional information on small bowel mucosa and disease extent.

Abstract
A consensus on the best imaging modality evaluating inflammatory bowel disease in the pediatric population is lacking and it is often unclear which modality to choose in specific clinical circumstances. Children with inflammatory bowel disease are exposed to ionizing radiation from multiple imaging studies performed at initial diagnosis, throughout treatment and during the follow-up period. This paper discusses the value of different imaging techniques in pediatric patients with inflammatory bowel disease and gives a review of the literature. In addition, particular features of inflammatory bowel disease in children including the predilection of affected segments in the gastrointestinal tract are highlighted. Based on current literature knowledge, we encourage an integrative approach to the interpretation of clinical and imaging data for diagnosis and follow-up in daily clinical settings.

Abstract
BACKGROUND AND AIMS Data on colon capsule endoscopy (CCE) in evaluating the small bowel and colon concurrently are rare. This study aimed to evaluate the accuracy of CCE in assessing disease activity of the small bowel and colon in pediatric Crohn's disease (CD) by comparison with magnetic resonance enterography (MRE), small-intestine contrast US (SICUS), and ileocolonoscopy. METHODS We prospectively enrolled 40 consecutive patients (22 male, 18 female, mean age 13.1 ± 3.1 years) with CD of the small bowel and colon. All underwent SICUS, MRE, CCE, and ileocolonoscopy sequentially over 5 days. All investigators were blinded to patient history and test results. Patients were classified as active or inactive for the small bowel and the colon according to specific criteria for each tool (simple endoscopic score for CD, Lewis score, US and magnetic resonance parameters of activity). For colon mucosa evaluation, ileocolonoscopy was the comparator. For the small bowel, a consensus panel was convened. RESULTS Sensitivity of CCE to detect colon inflammation was 89%, and specificity was 100%. The positive predictive value (PPV) and negative predictive value (NPV) of CCE for colon inflammation were 100% and 91%, respectively. In the small bowel, CCE showed 90% sensitivity, 94% specificity, with PPV and NPV of 95% and 90%, respectively. Accuracy parameters for SICUS (sensitivity 90%, specificity 83%) and MRE (sensitivity 85%, specificity 89%) were lower than those for CCE. No serious adverse events related to the CCE procedure or preparation were reported. CONCLUSIONS CCE is of great usefulness in evaluating both small bowel and colon mucosa in pediatric CD. This single, noninvasive tool makes it possible to evaluate the small-bowel and the colon concurrently with high diagnostic accuracy. Future multicenter studies need to define the role of CCE in the routine management of pediatric patients with CD. ( CLINICAL TRIAL REGISTRATION NUMBER NCT02199626.).

Abstract
BACKGROUND Small-bowel (SB) disease is a severe clinical entity among the phenotypes of Crohn's disease (CD). OBJECTIVE To assess sensitivity, specificity, and accuracy of magnetic resonance enterography (MRE), small-intestine contrast US (SICUS), and capsule endoscopy (CE) in the diagnosis of pediatric SB-CD. DESIGN Prospective, blinded, comparison study. SETTING Tertiary center for pediatric inflammatory bowel disease. PATIENTS Children with known or suspected CD. Diagnosis of SB obstruction at SICUS or MRE excluded patients from the study. INTERVENTION Patients underwent ileocolonoscopy, MRE, SICUS, and CE over a 7-day period. For the imaging evaluation, SB was divided into 3 segments: jejunum, proximal and mid ileum, and terminal ileum. MAIN OUTCOME MEASUREMENTS The performance of each method was compared to a consensus reference standard for upper SB and to ileocolonoscopy for the terminal ileum. RESULTS Twenty-five patients completed the study. In the jejunum, the sensitivity of SICUS and CE was 92%, which was not significantly higher than MRE (75%); the specificity of CE (61%) was significantly lower than that of MRE (P = .04). In the proximal and mid ileum, MRE and CE did not have significantly higher sensitivity (100%) than SICUS (80%), but CE was less specific (P > .05). At the terminal ileum, SICUS and MRE were slightly more sensitive than CE (94% vs. 81%); however, the latter was more specific. LIMITATIONS Use of the consensus reference standard for upper SB. Small number of patients. CONCLUSION SICUS, MRE, and CE are all effective options for imaging SB. An integrated use of different tools should be suggested to achieve a complete assessment of the SB in children with suspected or confirmed CD.

Abstract
PURPOSE OF REVIEW To review the various imaging modalities in the evaluation of pediatric inflammatory bowel disease (IBD) to determine disease location, clinical phenotype and the severity of disease in order to optimize treatment. RECENT FINDINGS Assessment of the extent, location and severity of IBD routinely involves imaging of the gastrointestinal tract. Cross-sectional modalities such as magnetic resonance enterography (MRE) and computed tomography enterography visualize the lumen, transmural involvement, extraintestinal manifestations and may facilitate decision-making in disease management. MRE has evolved as the imaging modality of choice for many pediatric IBD indications because it does not involve exposure to ionizing radiation. SUMMARY Advances in imaging modalities have revolutionized the assessment of children with IBD in recent years. Small-bowel follow-through is no longer considered the imaging modality of choice in this setting. Cross-sectional enterography is now preferred because, among other advantages, it can potentially distinguish active inflammation from fibrosis, characterize stricturing and penetrating complications, and diagnose extraintestinal manifestations. Although MRE avoids ionizing radiation exposure, it remains costly. Cross-sectional imaging and endoscopy complement each other in the development of objective measures for the assessment of disease activity and monitoring of response to treatment.

Video capsule endoscopy impacts decision making in pediatric IBD: a single tertiary care center experience. Inflamm Bowel Dis 2013; 19:2139-45.

Abstract
BACKGROUND Little is known about the impact of video capsule endoscopy (VCE) on decision making in pediatric patients with IBD. Moreover, few studies have reported on the outcomes of treatment changes made based on VCE findings. Our aim was to identify the added value of VCE in pediatric patients in a tertiary IBD center with established or suspected IBD, by assessing changes in treatments and outcomes before and after VCE. METHODS A retrospective chart review was performed in children with established (n = 66) or suspected (n = 17) IBD who underwent VCE. Diagnostic classifications, treatments, and clinical outcomes before and 1 year after VCE were compared. RESULTS Primary indications for VCE included patients treated for Crohn's disease (CD) with poor growth or active symptoms (60%), patients with ulcerative colitis/IBD-unclassified (19%), and suspected IBD (20%). Abnormal VCE was seen in 86% of patients with CD, of whom 75% underwent treatment escalation. One year after VCE, patients with CD improved in growth (mean z-scores at baseline and 12 months, -0.5 and 0.2, respectively; P < 0.0001), mean body mass index (18.3 and 19.8, respectively; P = 0.004), mean erythrocyte sedimentation rate (25 versus 16, respectively; P = 0.012), and median Harvey-Bradshaw Index (2 and 0, respectively; P = 0.003). VCE revealed more extensive disease than concurrent imaging modalities in 43% of the patients with CD. VCE "ruled out" IBD in 94% who had suspected IBD, whereas 50% with presumed ulcerative colitis/IBD-unclassified had a diagnosis changed to CD. CONCLUSIONS VCE provides additional clinical information that impacted management of pediatric patients with IBD in a tertiary IBD center and was associated with improved outcomes.

Abstract
Small bowel evaluation is crucial in children with suspected inflammatory bowel disease to differentiate Crohn's disease from other enteropathies, in making therapeutic decisions and planning the follow-up. Endoscopic investigation of small bowel has historically been difficult due to the length and tortuosity of the organ itself. New technology, introduced over the past decade, allows minimally invasive and detailed endoscopic evaluation of the entire small bowel mucosa. While understudied in the paediatric population, literature is emerging supporting the use of these techniques in children. In this review we will provide an overview on the currently available technology, on its feasibility in paediatric age and on the available literature concerning the use of enteroscopy in paediatric Crohn's disease.

Abstract
Investigation of the small bowel has been traditionally a challenge for pediatric gastroenterologists due to its location, anatomical tortuosity, and invasiveness of the available techniques. Recently, there has been a remarkable improvement in imaging and endoscopic tools aimed at exploring successfully the small intestine in inflammatory bowel disease. The former are represented by ultrasonography (either alone or with administration of oral contrast agents) and by magnetic resonance: both have provided accurate methods to detect structural bowel changes, diminishing patient discomfort and precluding radiation hazard. The use of traditional radiologic techniques such as fluoroscopy have been markedly reduced due to radiation exposure and inability to depict transmural inflammation or extraluminal complications. Among the novel endoscopic tools, capsule endoscopy and balloon-assisted enteroscopy have tremendously opened new diagnostic and therapeutic perspectives, by allowing the direct visualization of small intestinal mucosa and, through enteroscopy, histological diagnosis as well as therapeutic interventions such as stricture dilation and bleeding treatment. These endoscopic techniques should always be preceded by imaging of the intestine in order to identify strictures. This review describes the most recent progress with the employment of novel imaging and endoscopic methodologies for investigating the small bowel in children with suspected or established Crohn's disease.

Abstract
AIM To determine the usefulness of magnetic resonance enterography (MRE) in treatment for paediatric patients with Crohn's disease. METHODS To evaluate small bowel involvement, 45 children with Crohn's disease were scheduled for MRE. Two radiologists blinded to the patient data independently re-evaluated the images. Findings in images were compared to macroscopic findings at surgery or endoscopy. RESULTS The terminal ileum was visualized in all with a completed procedure (43/45). The treatment remained conservative in 74% after imaging. In all 13 patients who underwent ileocolonoscopy within 3 months of MRE, the MRE findings were comparable with the macroscopic findings or revealed a more extensive disease. Bowel resection was performed in 26% after imaging. The macroscopic findings in the bowel corresponded to the MRE findings in 73%. In three MRE suggested a more severe disease than was verified intraoperatively. CONCLUSIONS Magnetic resonance enterography identifies disease involvement in the small bowel in young patients with Crohn's disease and may guide decisions on the need for intestinal surgery or adjustment of medication.

Abstract
Guidelines for clinical practice are intended to suggest preferable approaches to particular medical problems as established by interpretation and collation of scientifically valid research, derived from extensive review of published literature. When data that will withstand objective scrutiny are not available, a recommendation may be made based on a consensus of experts. Guidelines are intended to apply to the clinical situation for all physicians without regard to specialty. Guidelines are intended to be flexible, not necessarily indicating the only acceptable approach, and should be distinguished from standards of care that are inflexible and rarely violated. Given the wide range of choices in any health-care problem, the physician should select the course best suited to the individual patient and the clinical situation presented. These guidelines are developed under the auspices of the American College of Gastroenterology and its Practice Parameters Committee. Expert opinion is solicited from the outset for the document. The quality of evidence upon which a specific recommendation is based is as follows: Grade A: Homogeneous evidence from multiple well-designed randomized (therapeutic) or cohort (descriptive) controlled trials, each involving a number of participants to be of sufficient statistical power. Grade B: Evidence from at least one large well-designed clinical trial with or without randomization, from cohort or case-control analytic studies, or well-designed meta-analysis. Grade C: Evidence based on clinical experience, descriptive studies, or reports of expert committees. The Committee reviews guidelines in depth, with participation from experienced clinicians and others in related fields. The final recommendations are based on the data available at the time of the production of the document and may be updated with pertinent scientific developments at a later time.

Abstract
Inflammatory bowel diseases (IBDs), including Crohn disease (CD) and ulcerative colitis (UC), often affect children and adolescents. Their diagnosis is based on the integration of clinical, biological, endoscopic, histological and radiological data. The paediatric radiologist may help the clinician in many ways. In children presenting with symptoms compatible with IBD, gut exploration by US may identify those who will benefit from more invasive explorations including endoscopy. During the process of diagnosis, small bowel exploration has a crucial role in differentiating CD from UC and in classifying the disease into subphenotypes. Finally, new imaging methods are useful during patient follow-up for assessing disease activity and for the diagnosis of complications.
