Abstract
BACKGROUND AND AIM The PillCam patency capsule (PC) without a radio frequency identification tag was released to preclude retention of the small bowel capsule endoscope (CE) in Japan in 2012. We conducted a multicenter study to determine tag-less PC-related adverse events (AEs). METHODS We first conducted a retrospective survey using a standardized data collection sheet for the clinical characteristics of PC-related AEs among 1096 patients collected in a prospective survey conducted between January 2013 and May 2014 (Cohort 1). Next, we retrospectively investigated additional AEs that occurred before and after Cohort 1 within the period June 2012 and December 2014 among 1482 patients (Cohort 2). RESULTS Of the 2578 patients who underwent PC examinations from both cohorts, 74 AEs occurred among 61 patients (2.37%). The main AEs were residual parylene coating in 25 events (0.97%), PC-induced small bowel obstruction, suspicious of impaction, in 23 events (0.89%), and CE retention even after patency confirmation in 10 events (0.39%). Residual parylene coating was significantly associated with Crohn's disease (P < 0.01). Small bowel obstruction was significantly associated with physicians with less than 1 year of experience handling the PC and previous history of postprandial abdominal pain (P < 0.01 and P < 0.03, respectively). CE retention was ascribed to erroneous judgment of PC localization in all cases. CONCLUSIONS This large-scale multicenter study provides evidence supporting the safety and efficiency of a PC to preclude CE retention. Accurate PC localization in patients without excretion and confirmation of previous history of postprandial abdominal pain before PC examinations is warranted (UMIN000010513).

Abstract
BACKGROUND Advances in microelectronics have greatly expanded the capabilities and clinical potential of ingestible electronic devices. AIM To provide an overview of the structure and potential impact of ingestible devices in development that are relevant to the gastrointestinal tract. METHODS We performed a detailed literature search to inform this narrative review. RESULTS Technical success of ingestible electronic devices relies on the ability to miniaturise the microelectronic circuits, sensors and components for interventional functions while being sufficiently powered to fulfil the intended function. These devices offer the advantages of being convenient and minimally invasive, with real-time assessment often possible and with minimal interference to normal physiology. Safety has not been a limitation, but defining and controlling device location in the gastrointestinal tract remains challenging. The success of capsule endoscopy has buoyed enthusiasm for the concepts, but few ingestible devices have reached clinical practice to date, partly due to the novelty of the information they provide and also due to the challenges of adding this novel technology to established clinical paradigms. Nonetheless, with ongoing technological advancement and as understanding of their potential impact emerges, acceptance of such technology will grow. These devices have the capacity to provide unique insight into gastrointestinal physiology and pathophysiology. Interventional functions, such as sampling of tissue or luminal contents and delivery of therapies, may further enhance their ability to sharpen gastroenterological diagnoses, monitoring and treatment. CONCLUSIONS The development of miniaturised ingestible microelectronic-based devices offers exciting prospects for enhancing gastroenterological research and the delivery of personalised, point-of-care medicine.

Abstract
This paper presents new perspectives on photonic technologies for capsule endoscopy. It first presents a review of conventional endoscopy (upper endoscopy and colonoscopy), followed by capsule endoscopy (CE), as well as their techniques, advantages, and drawbacks. The technologies for CEs presented in this paper include integration with the existing endoscopic systems that are commercially available. Such technologies include narrow-band imaging (NBI), photodynamic therapy (PDT), confocal laser endomicroscopy (CLE), optical coherence tomography (OCT), and spectroscopy in order to improve the performance of the gastrointestinal (GI) tract examination. In the context of NBI, two optical filters were designed and fabricated for integration into endoscopic capsules, allowing for the visualization of light centered at the 415 nm and 540 nm wavelengths. These optical filters are based on the principle of Fabry-Perot and were made of thin films of titanium dioxide (TiO2) and silicon dioxide (SiO2). Moreover, strategies and solutions for the adaptation of ECs for PDT are also discussed.

Abstract
PURPOSE To assess the efficacy of double-balloon endoscopy (DBE) for the detection of small-bowel strictures in Crohn's disease (CD). METHODS This tertiary-referral hospital cohort study was conducted between January 2018 and May 2022. CD patients with symptoms of small-bowel stricture were enrolled sequentially. All of the patients were subjected to both computed tomography enterography (CTE) and DBE, and their symptoms of stricture were assessed using the Crohn's Disease Obstructive Score (CDOS). The diagnostic yield of DBE was compared to that of CTE, and the relationship between the DBE findings and CDOS was investigated. The factors influencing the DBE diagnosis were examined using Cox regression analysis. RESULTS This study included 165 CD patients. The CDOS scores were higher in 95 patients and lower in 70 patients. DBE detected 92.7% (153/165) and CTE detected 85.5% (141/165) of the strictures. The DBE diagnostic yields were 94.7% (90/95) in the high CDOS patients and 91.4% (64/70) in the low CDOS patients (P = 0.13). Patients with a history of abdominal surgery and abscess had a lower diagnosis rate in the multivariate analysis. CONCLUSION DBE has been demonstrated to be an efficient diagnostic method for detecting small bowel strictures in CD patients. Additionally, there was no difference in the diagnostic yields between patients with low and high obstructive scores.

Abstract
Ingestible electronics are promising platforms for on-demand health monitoring and drug delivery. However, these devices and their actuators must operate in the gastrointestinal (GI) environment, which has a pH range of 1 to 8. Drug delivery systems using electrochemical dissolution of metal films are particularly susceptible to pH changes. Optimal operation in this dynamic environment stands to transform our capacity to help patients across a range of conditions. Here we present an energy-efficient ingestible electronic electrochemical drug delivery system to support subjects through operation in this dynamic environment. The proposed system consists of a drug reservoir sealed with an electrochemically dissolvable gold membrane and an electronic subsystem. An electronic subsystem controls the rate of gold dissolution by sensing and adapting to the pH of the GI environment and provides an option for energy-efficient drug delivery, reducing energy consumption by up to 42.8 %. Integrating the electronics with electrochemical drug delivery enables the proposed system to adapt to the dynamic physiological environments which makes it suitable for drug and/or therapeutic delivery at different locations in the GI tract.

Abstract
PURPOSE OF REVIEW Capsule endoscopy is widely recognized as a safe and effective procedure to evaluate the small bowel and/or the colon noninvasively. Although infrequent, capsule retention is the most feared adverse event related to this technique. A better knowledge of risk factors, improvement of patients' selection and precapsule patency assessment may further contribute to reducing the incidence of capsule retention, even in patients at increased risk for this complication. RECENT FINDINGS This review addresses the main risk factors for capsule retention, strategies for risk reduction such as patients' selection, dedicated cross-sectional imaging and rational use of the patency capsule, as well as management options and outcomes in the case of capsule retention. SUMMARY Capsule retention is infrequent, and it is usually manageable conservatively with favorable clinical outcomes. Patency capsules and dedicated small-bowel cross-sectional techniques such as CT or MR enterography should be used selectively and are both effective in decreasing the rate of capsule retention. However, none of them can completely eliminate the risk of retention.

Abstract
INTRODUCTION retention is the most common adverse event of the small bowel capsule endoscopy procedure. Patency capsule (Medtronic, Dublin, Ireland) and magnetic resonance enterography are two diagnostic methods that can prevent small bowel capsule endoscopy retention. The aim of this study was to evaluate the predictive value of these two diagnostic methods. MATERIAL AND METHODS a prospective, comparative and observational study was performed in patients with established Crohn's disease. All patients had undergone magnetic resonance enterography and patency capsule procedures. If the patency capsule was not retained, the patient underwent a small bowel capsule endoscopy; otherwise, double balloon enteroscopy was performed to locate the stenosis. Magnetic resonance enterography predictive criteria for retention were analyzed in all cases. Sensitivity, specificity, positive predictive value and negative predictive value of the patency capsule and magnetic resonance enterography compared to small bowel capsule endoscopy or double balloon enteroscopy were calculated. RESULTS forty patients were included (24 female, 55 ± 13 years old). Retention criteria with capsule endoscopy or double balloon enteroscopy were found in six patients, agreeing in five cases with patency capsule and in three cases with magnetic resonance enterography. Sensitivity, specificity, positive predictive value, negative predictive value and Kappa coefficient for predicting retention with the patency capsule were 83 %, 100 %, 100 % and 97 %, respectively, and 50 %, 91 %, 50 % and 91 %, respectively, with magnetic resonance enterography. CONCLUSIONS patency capsule has a higher sensitivity and positive predictive value than magnetic resonance enterography for preventing small bowel capsule endoscopy retention in Crohn's disease patients.

Abstract
BACKGROUND AND AIMS Capsule endoscopy (CE) and deep enteroscopy (DE) can be useful for diagnosing and treating suspected small-bowel disease. Guidelines and detailed recommendations exist for the use of CE/DE, but comprehensive quality indicators are lacking. The goal of this task force was to develop quality indicators for appropriate use of CE/DE by using a modified RAND/UCLA Appropriateness Method. METHODS An expert panel of 7 gastroenterologists with diverse practice experience was assembled to identify quality indicators. A literature review was conducted to develop a list of proposed quality indicators applicable to preprocedure, intraprocedure, and postprocedure periods. The panelists reviewed the literature; identified and modified proposed quality indicators; rated them on the basis of scientific evidence, validity, and necessity; and determined proposed performance targets. Agreement and consensus with the proposed indicators were verified using the RAND/UCLA Appropriateness Method. RESULTS The voting procedure to prioritize metrics emphasized selecting measures to improve quality and overall patient care. Panelists rated indicators on the perceived appropriateness and necessity for clinical practice. After voting and discussion, 2 quality indicators ranked as inappropriate or uncertain were excluded. Each quality indicator was categorized by measure type, performance target, and summary of evidence. The task force identified 13 quality indicators for CE and DE. CONCLUSIONS Comprehensive quality indicators have not existed for CE or DE. The task force identified quality indicators that can be incorporated into clinical practice. The panel also addressed existing knowledge gaps and posed research questions to better inform future research and quality guidelines for these procedures.

Abstract
Power receiving coils (PRCs) with ferrite cores are widely used in wireless power transfer (WPT) for capsule robots (CRs) to enhance the power transfer efficiency (PTE). However, due to the large demagnetizing factor, the traditional one-dimensional hollow cylindrical ferrite core has its limitations in volume and performance improvement, which needs to be reconsidered. To this end, we propose a novel PRC equipped with a delicate, lightweight, and more efficient ferrite core structure in this paper. Different from the traditional ferrite core structure, the proposed design composed of distributed ferrite cores and end covers aims to minimize the negative impact of demagnetization on PTE and enhance the magnetic flux concentration. Based on the analysis of the PTE and mutual inductance, influence of the introduced cores on the WPT system is emphasized. The relationship between the change of ferrite core structures and the demagnetizing factors, as well as the effective permeability, is analyzed and simulated. Prototypes of PRCs with different ferrite core configurations are established, tested, and compared to validate the performance enhancement. Experimental results on the power delivered to the load (PDL) and PTE indicate that the proposed design has a volume reduction of 24.4% but performance enhancement of 36% compared with the traditional one with hollow cylindrical ferrite core, thanks to the structure-based demagnetizing factor optimization.

Abstract
Crohn’s disease (CD) is a chronic inflammatory disorder with a predilection for the small bowel. Although awareness of this disorder has increased over the years, it remains a diagnostic challenge for many physicians. This is exacerbated by the rising incidence and high recurrence rate following therapy in certain individuals. It is currently agreed that a multimodality approach is the best one, but with the advent of new modalities, that could be changing. Furthermore, given its impact on the mental health of patients and the cost of treatment, it is pertinent that we arrive at not only convenient but accurate modalities in its diagnosis and management. Among these investigative modalities is the relatively novel capsule endoscopy (CE) that not only provides a more patient-friendly alternative but avoids the need for invasiveness. Asides from its diagnostic capability, its influence on therapy and monitoring of known CD patients following treatment has been shown. This article has reviewed the current literature comparing the relevance of CE with other available modalities in diagnosing CD patients. We explored its therapeutic impact and how it influences monitoring post-treatment in CD. This article also discusses the complications of CE and the possible solutions to these complications in the future.

Abstract
BACKGROUND AND AIM Minimal data are available regarding the performance of video capsule endoscopy (VCE) in patients who underwent bariatric surgery. We aimed to report indications, feasibility, and safety of VCE performed after bariatric surgery, specifically focusing on diagnosis rates of Crohn's disease (CD) in this population. METHODS A retrospective analysis of all VCE procedures was performed between January 2015 and December 2019. All patients who underwent bariatric surgery prior to VCE were included. Indication for VCE, ingestion methods, completion rates, retention rates, and endoscopic findings were recorded. RESULTS A total of 1,255 patients underwent VCE examination during the study period, of which 31 (2.5%) underwent bariatric surgery prior to VCE. The most common bariatric surgery was laparoscopic sleeve gastrectomy (16 patients, 51.6%), and the most common indication for VCE was evaluation of iron deficiency anemia (14 patients, 45.1%). The majority of patients ingested the capsule independently, without endoscopic assistance (20, 64.5%). Although a patency capsule was not used in our cohort, no events of capsule retention were documented. Mean transit time was 4.32 h. Only 4 events of incomplete examination were recorded. Over a median follow-up of 27.5 months (IQR 13.0-34.2), 10 patients (31.2%) had a final diagnosis of CD with a median Lewis score of 225 (IQR 135-900). CONCLUSION VCE is a feasible and safe procedure after bariatric surgery. Oral ingestion does not carry risk of retention. It is an effective means of diagnosis of small-bowel CD in this population.

Abstract
Capsule endoscopy is an effective tool for evaluating small bowel diseases. Capsule retention is a complication of capsule endoscopy, but capsule disruption after retention has not been thoroughly studied. Only a few cases of capsule disruption have been reported. We report a case of capsule disruption after prolonged retention. A 73-year-old woman underwent capsule endoscopy for the evaluation of anemia. One week later, capsule retention was observed on radiography. Capsule removal was advised, but she refused because she did not have any symptoms. After 20 months, computed tomography revealed disrupted capsule fragments. Capsule removal was strongly recommended, and the patient agreed. All disrupted capsule fragments were removed using double-balloon endoscopy without complications. Intestinal perforation had been prevented by removing the disrupted capsule before the battery fluid leaked into the intestinal tract. Capsule retention, documented by imaging, should be addressed by removing the retained capsule immediately before capsule disruption occurs.

Abstract
Endoscopy is the mainstay of inflammatory bowel disease (IBD) evaluation and the pillar of colorectal cancer surveillance. Endoscopic equipment, both hardware and software, are advancing at an incredible pace. Virtual chromoendoscopy is now widely available, allowing the detection of subtle inflammatory changes, thus reducing the gap between endoscopic and histologic assessment. The progress in the field of artificial intelligence (AI) has been remarkable, and numerous applications are now in an advanced stage of development. Computer-aided diagnosis (CAD) systems are likely to reshape most of the evaluations that are now prerogative of human endoscopists. Furthermore, sophisticated tools such as endocytoscopy and probe-based confocal laser endomicroscopy (pCLE) are enhancing our assessment of inflammation and dysplasia. Finally, pCLE combined with molecular labeling could pave the way to a new paradigm of personalized medicine. This review aims to summarize the main changes that occurred in the field of IBD endoscopy and to explore the most promising novelties.

Abstract
The retention of the capsule used during small bowel capsule endoscopy (SBCE) is a serious complication that can occur in patients with known or suspected small bowel stenosis, and a prior evaluation of the patency of the gastrointestinal (GI) tract is therefore essential. Patency capsule (PC) is a non-diagnostic capsule the same size as the diagnostic SBCE. To date, there are no clear guidelines regarding the contraindications for undergoing a PC evaluation prior to SBCE. Each small bowel disorder has specific occasions to inhibit the progress of PC and SBCE, even though they do not have any stenotic symptoms or abnormalities on imaging. In this review, we summarize the indications and limitations of PC prior to SBCE, especially the contraindications, and discuss clinical scenarios in which even PC should be avoided, and therefore such areas of stenosis should be evaluated by alternative modalities. We thus propose this new algorithm to evaluate the patency of the GI tract for patients with suspected and known small bowel stenosis in order that they may undergo SBCE safely.

Assessment of Capsule Endoscopy Utilizing Capsocam Plus in Patients With Suspected Small Bowel Disease Including Pilot Study With Remote Access Patients During Pandemic. J Can Assoc Gastroenterol 2021; 4:269-273. [PMID: 34988365 PMCID: PMC8697548 DOI: 10.1093/jcag/gwaa042] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Accepted: 11/16/2020] [Indexed: 11/28/2022] Open
Abstract
Background CapsoCam Plus is a capsule endoscopy (CE) system that utilizes four cameras
to capture a panoramic view. This has theoretical advantage over
conventional forward-viewing CE with limited field of view. Its ease of
administration without requiring any additional equipment during the
recording also provides a unique opportunity for patients to self-administer
the test. We aimed to evaluate real-life experience using this novel system
and to determine feasibility of a remote access program. Methods Retrospective chart review was conducted for consecutive adult outpatients
who underwent CE using CapsoCam Plus. Patients with significant challenges
for in-person procedures were selected for remote access through mail
courier services. Gastric transit time, small bowel transit time, completion
rate, diagnostic yield and adverse events were compared between remote
access versus usual practice. Results Ninety-four patients (52.1% male) were included, with 28 in remote access
program. Most common indication was gastrointestinal bleeding (85.1%).
Complete examination was achieved in 87 patients. Five (5.3%)
patients’ capsule remained in stomach during the recording, while two
(2.1%) patients missed capsule retrieval. Median small bowel and gastric
transit times were 231.9 (interquartile range [IQR] 169.5–308.2) and
27.6 (IQR 13.8–63.5) minutes, respectively. Diagnostic yield was
23.4%. There was no difference in completion rate or transit times between
two groups, but diagnostic yield was higher in remote access group (odds
ratio 3.80, 95% confidence interval 1.28–11.31). One patient required
elective endoscopic retrieval of capsule. Conclusion CapsoCam Plus can be safely administered remotely with a high degree of
success, which may facilitate timely investigations while limiting
nonessential physical interactions during pandemic.

Abstract
The small bowel is the longest organ within the gastrointestinal tract. The emergence of small bowel capsule endoscopy (SBCE) over the last 20 years has revolutionized the investigation and diagnosis of small bowel pathology. Its utility as a non-invasive and well-tolerated procedure, which can be performed in an outpatient setting, has made it a valuable diagnostic tool. The indications for SBCE include obscure gastrointestinal bleeding, small bowel Crohn's disease, and, less frequently for screening in polyposis syndromes, celiac disease, or other small bowel pathology. Currently, there are several small bowel capsules on the market from different manufacturers; however, they share many technological features. The European Society of Gastrointestinal Endoscopy (ESGE) only recently developed a set of key quality indicators to guide quality standards in this area. Many of the technical aspects of capsule endoscopy still feature a degree of uncertainty in terms of optimal performance. Incomplete studies due to slow transit through the bowel, poor imaging secondary to poor preparation, and the risk of capsule retention remain frustrations in its clinical utility. Capsule review is a time-consuming process; however, artificial intelligence and machine learning offer opportunities to improve this. This narrative review examines our current standing in a number of these aspects and the potential to further the application of SBCE in order to maximize its diagnostic utility.

Abstract
Crohn’s disease (CD) is a chronic inflammatory disorder that may involve the gastrointestinal tract from the mouth to the anus. Habitual disease monitoring is highly important during disease management, aiming to identify and treat disease exacerbations, in order to avoid immediate and future complications. Currently, ilio-clonoscopy is the gold standard for mucosal assessment. However, the procedure is invasive, involves sedation and allows for visualization of the colon and only a small part of the terminal ileum, while most of the small bowel is not visualized. Since CD may involve the whole length of the small bowel, the disease extent might be underestimated. Capsule endoscopy (CE) provides a technology that can screen the entire bowel in a non-invasive procedure, with minimal side effects. In recent years, this technique has gained in popularity for CD evaluation and monitoring. When CE was first introduced, two decades ago, the fear of possible capsule retention in the narrowed inflamed bowel lumen limited its use in CD patients, and a known CD located at the small bowel was even regarded as a relative contraindication for capsule examination. However, at present, as experience using CE in CD patients has accumulated, this procedure has become one of the accepted tools for disease diagnosis and monitoring. In our current review, we summarize the historic change in the indications and contraindications for the usage of capsule endoscopy for the evaluation of CD, and discuss international recommendations regarding CE’s role in CD diagnosis and monitoring.

Abstract
The impact of small-bowel (SB) capsule endoscopy and device-assisted enteroscopy on clinical practice, since their introduction 2 decades ago, has been remarkable. These disruptive technologies have transformed the investigation and management of SB pathology and now have a firmly established place in guidelines and clinical algorithms. Furthermore, recent years have witnessed innovations, driven by the demand of new goals in the management of inflammatory bowel disease (IBD), such as mucosal healing and evolving strategies based on tight monitoring and accelerated escalation of care. These developments in SB endoscopy have also been paralleled by refinement in dedicated radiological SB imaging technologies. This updated review highlights the current state of the art and more recent innovations with a focus on their role in IBD.

Abstract
Ingestible sensor systems are unique tools for obtaining physiological data from an undisturbed gastrointestinal tract. Since their dimensions correspond to monolithic oral dosage forms, such as enteric coated tablets or hydrogel matrix tablets, they also allow insights into the physiological conditions experienced by non-disintegrating dosage forms on their way through the gastrointestinal tract. In this work, the different ingestible sensor systems which can be used for this purpose are described and their potential applications as well as difficulties and pitfalls with respect to their use are presented. It is also highlighted how the data on transit times, pH, temperature and pressure as well as the data from different animal models commonly used in drug product development such as dogs and pigs have contributed to a deeper mechanistic understanding of oral drug delivery.

Abstract
Capsule endoscopy (CE) is a recently developed diagnostic method for diseases of the small bowel that is non-invasive, safe, and highly tolerable. Its role in patients with inflammatory bowel disease has been widely validated in suspected and established Crohn’s disease (CD) due to its ability to assess superficial lesions not detected by cross-sectional imaging and proximal lesions of the small bowel not evaluable by ileocolonoscopy. Because CE is a highly sensitive but less specific technique, differential diagnoses that can simulate CD must be considered, and its interpretation should be supported by other clinical and laboratory indicators. The use of validated scoring systems to characterize and estimate lesion severity (Lewis score, Capsule Endoscopy Crohn’s Disease Activity Index), as well as the standardization of the language used to define the lesions (Delphi Consensus), have reduced the interobserver variability in CE reading observed in clinical practice, allowing for the optimization of diagnoses and clinical management strategies. The appearance of the panenteric CE, the incorporation of artificial intelligence, magnetically-guided capsules, and tissue biopsies are elements that contribute to CE being a promising, unique diagnostic tool in digestive tract diseases.

INTRODUCTION cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) is a rare illness. Capsule retention (CR) has been reported in a few cases of CMUSE. METHODS we present four cases of CMUSE with CR. None of the patients showed any symptoms or signs of small bowel obstruction before capsule endoscopy (CE). All patients denied a history of non-steroidal anti-inflammatory drugs intake, radiotherapy treatment or abdominal surgery. RESULTS CE disclosed circumferential stenosis with or without ulcers in the small bowel, some accompanied by mucosal edema, white spots and nodules. All patients underwent an elective surgery to remove the retained capsule and resect the lesions. CONCLUSION CE plays a positive role in diagnosing CMUSE. CE findings are as important as CR to alert about the diagnosis of CMUSE.

Abstract
BACKGROUND Capsule endoscopy has played a significant role in small bowel investigation, providing the opportunity of detecting neoplastic lesions to a greater degree and at an earlier stage than other diagnostic procedures. Failure to excrete the capsule with the feces within 48 h can lead to capsule retention with increased risk of further complications such as bowel obstruction and perforation. Capsule retention can remain undetected in case of incomplete follow-up and poor patient compliance. Acute small bowel obstruction as late as many months following capsule endoscopy investigation is very rare, with only a few cases reported in the published literature. We herein report a rare case of prolonged capsule retention which remained undiagnosed, resulting in small bowel obstruction 6 months after the initial investigation. CASE REPORT An 82-year-old woman presented with abdominal pain and symptoms suggestive of intestinal obstruction. The patient history included a capsule endoscopy investigation because of episodes of abdominal pain 6 months prior to admission. Both the outcome of the investigation and the excretion of the capsule remained undetermined due to her history of dementia and follow-up failure. Radiologic investigations identified the capsule causing small bowel obstruction. Upon surgery, the capsule was found to be impacted in a stenotic small bowel lesion, and a segmental small bowel resection was performed. Histologic examination revealed the presence of a stenotic small bowel neuroendocrine tumor. CONCLUSIONS Appropriate follow-up is necessary to diagnose the complication of capsule retention which, if it remains unrecognized, can cause life-threatening complications as late as many months after capsule endoscopy.

Abstract
A 28-year-old male with Crohn’s disease presented with hematochezia and severe anemia. Upon evaluation, no source of bleeding was identified with colonoscopy or esophagogastroduodenoscopy; therefore, a video capsule was placed. Following capsule placement, the patient developed severe abdominal pain. Abdominal X-ray revealed the capsule at the ileocecal valve, indicating it was possibly stuck in a stricture. To reduce inflammation, intravenous steroids were started to assist with capsule passage. Following unsuccessful passage and continual abdominal pain, surgical investigation visualized a mass arising from a jejunal Crohn’s stricture. Despite multiple inspections of the resected small bowel, the capsule was not located. Intraoperative X-ray revealed the capsule inside the large bowel, indicating capsule passage through the stricture. Final pathology revealed metastatic poorly differentiated adenocarcinoma. This case demonstrates management of a retained capsule in Crohn’s patients and emphasizes the importance of considering small bowel adenocarcinoma in Crohn’s patients with obstructive signs.

Abstract
Introduction The malfunction of capsule endoscopy (CE) devices is a significant reason for the failure of CE procedures, which could hinder and prevent diagnosis. Unfortunately, malfunction-related adverse events (AEs) caused by CE devices are rarely reported in publications. Although most malfunction-related AEs could not lead to physical harm, they could reduce the efficiency of medical care and increase medical costs. The manufacturer and user facility device experience (MAUDE) database, a publicly accessible resource for patient safety, contains not only the common complications of CE but also valuable malfunction-related AEs, which have been underutilized. Therefore, the study aims to discover and analyze the possible AEs associated with CE and demonstrate the utility of the MAUDE reports to promote patient safety. Materials and Methods We acquired MAUDE reports of CE systems from January 01, 2008, to July 31, 2020, through a systematic search strategy. We utilized the manufacturers, brand names, and product codes as search terms from which medical device reports including structured data and narrative texts were extracted, followed by a manual review of the narrative texts, reporter occupation, device involved, event type and the phase of the event; finally, patient outcomes were recorded and analyzed as per CE categories and characteristics. Results A total of 377 CEs medical device reports were retrieved, and 342 reports were included after reviewing. There were 327 mandatory reports (96%) and 15 voluntary reports (4%). These reports referred to capsule endoscope (n = 213), sensing system (n = 66), patency capsule (n = 38), and capsule delivery device (n = 26). A total of 349 CE-related AEs were identified, including complications (n = 228), malfunction-related AEs (n = 109), and other events (n = 12). The composition of AEs was not the same for the CE devices. Complications were major AEs of capsule endoscope and patency capsule, but malfunction-related AEs were the most common in AEs of sensing systems and capsule delivery devices. Conclusion MAUDE serves as an invaluable data source for investigating malfunction-related AEs. In addition to common complications, malfunction of CE devices could threaten patient safety in CE procedures. Improving awareness of the malfunction of CE devices and raising adequate training for staff working in gastrointestinal (GI) endoscopic units could be critical and beneficial in preventing malfunction-related AEs.

Abstract
BACKGROUND Despite the proven efficacy of immune checkpoint inhibitors (ICIs) against various types of malignancies, they have been found to induce immune-related adverse events, such as enterocolitis; however, the clinical features of ICI-induced enterocolitis remain to be sufficiently elucidated, which is significant, considering the importance of early detection in the appropriate management and treatment of ICI-induced enterocolitis. Therefore, the current study aimed to determine the utility of capsule endoscopy as a screening tool for ICI-induced enterocolitis. METHODS This single-center, prospective, observational study was conducted on patients with malignancy who received any ICI between April 2016 and July 2020 at Keio University Hospital. Next, second-generation capsule endoscopy (CCE-2) was performed on day 60 after ICI initiation to explore the entire gastrointestinal tract. RESULTS Among the 30 patients enrolled herein, 23 underwent CCE-2. Accordingly, a total of 23 findings were observed in 14 (60.8%) patients at any portion of the gastrointestinal tract (7 patients in the colon, 4 patients in the small intestine, 2 patients in both the colon and the small intestine, and 1 patient in the stomach). After capsule endoscopy, 2 patients (8.7%) developed ICI-induced enterocolitis: both had significantly higher Capsule Scoring of Ulcerative Colitis than those who had not developed ICI-induced enterocolitis (p = 0.0455). No adverse events related to CCE-2 were observed. CONCLUSIONS CCE-2 might be a safe and useful entire intestinal tract screening method for the early detection of ICI-induced enterocolitis in patients with malignancies.

Abstract
INTRODUCTION Capsule endoscopy (CE) is an established modality in the diagnostic algorithm of small bowel (SB) pathology. Its use has expanded for investigation of upper and lower gastrointestinal diseases with similar prototypes. AREAS COVERED This review covers the role and recent advances of CE, as a non-invasive investigative tool. EXPERT OPINION The use of upper gastrointestinal CE is useful in patients who require surveillance for varices particularly in the current era of the COVID-19 pandemic. It has also shown high accuracy in the detection of upper gastrointestinal hemorrhage in patients presenting with a suspicion of hemorrhage. Findings on CE help to guide further management by device-assisted enteroscopy. The data on colon CE suggest comparable diagnostic accuracy to colonoscopy for polyp detection; however, more evidence is required in the high-risk group. Crohn's CE has become an integral part of the management of patients with Crohn's disease offering a comparative assessment tool post escalation of therapy. Artificial intelligence within CE has demonstrated similar if not better diagnostic yield compared to the human with a significantly shorter reading time. Artificial intelligence is likely to be in-built within CE reading platforms over the next few years minimizing reporting time and human error.

Abstract
STUDY AIMS The PillCam patency capsule (PPC) is an Agile tag-less patency capsule used to evaluate gastrointestinal (GI) patency. We determined the appropriate use of PPC to preclude subsequent small bowel capsule endoscopy (SBCE) retention. METHODS This prospective multicenter study consecutively enrolled patients indicated for SBCE with suspected or established small bowel stenosis. Excretion of an intact PPC or its radiologic visualization in the large bowel was considered GI patency. Primary and secondary study endpoints were SBCE retention rates in patients with confirmed patency and identification of factors associated with patency and SBCE retention, respectively. RESULTS Of 1096 patients enrolled in the study, patency was confirmed in 976 (89.1%). PPC excretion occurred in 579 patients. Of the remaining 517 patients, patency was confirmed using imaging modalities in 401 (77.5%). SBCE retention occurred in five (0.51%) of 963 patients who underwent SBCE: 1.0% in established Crohn's disease (CD) patients, 0% in suspected CD, 0% in tumors, and 1.6% in patients with obscure GI bleeding, for which PPC localization had been radiographically misinterpreted. The non-confirmation of patency was associated with established CD, stenosis identified using imaging modalities, abdominal fullness, serum albumin levels <4.0 g/dL, and previous small bowel obstruction (adjusted odds ratios: 4.21, 2.60, 2.47, 2.12, and 2.00; 95% confidence intervals: 2.62-6.78, 1.62-4.17, 1.43-4.27, 1.32-3.40, and 1.15-3.47, respectively). CONCLUSIONS The PillCam™ patency capsule helped preclude SBCE retention in most patients, but its accurate localization was essential for cases without excretion (Study registered the University Hospital Medical Information Network, #UMIN000010513).

Abstract
BACKGROUND A full spectrum of video capsule endoscopy (VCE) adverse events over the past two decades has not been evaluated. We aimed to determine pooled rates, predictors and temporal-trend of VCE adverse events over the past two decades. METHODS Systematic search of PubMed and EMBASE for English-language publications reporting VCE adverse events (January 1, 2000 to March 31, 2019). Data were extracted independently by two investigators. Pooled VCE adverse event rates were calculated using the random or fixed model as appropriate. Predictors and temporal-trend of each adverse event were performed by meta-regression analyses. RESULTS In total, 402 studies were identified, including 108,079 VCE procedures. Rate of retention, swallow disorder, aspiration, technical failure, and procedural adverse events were 0.73% (95% confidence interval [CI] 0.59-0.89%), 0.75% (95% CI 0.43-1.13%), 0.00% (95% CI 0.00-0.00%), 0.94% (95% CI 0.65-1.28%), 0.67% (95% CI 0.32-1.10%), respectively; incomplete examination rate of esophagus, stomach, small bowel, and colon were 9.05%, 7.69%, 12.08%, 19.19%, respectively. Patency capsule reduced retention rate by 5.04%, whereas known inflammatory bowel disease increased retention rate by 4.29%. Elder was the risk and protective factor for small bowel incomplete examination (0.30%) and swallow disorder (- 0.72%), respectively. Rates of retention and small bowel incomplete examination significantly declined over time (P = .0006 and P < .0001).. CONCLUSIONS VCE adverse event rates were generally low, and retention and small bowel incomplete examination rates declined over the past two decades. Patients with known inflammatory bowel disease or elder should be alerted to high risk of retention or small bowel incomplete examination (PROSPERO: CRD42019139595).

Abstract
Small bowel capsule endoscopy (SBCE) was introduced into clinical practice almost 20 years ago and, nowadays, it is an essential tool for the study of the small bowel. SBCE allows a radiation-free examination of the entire mucosal surface of the small bowel with high-quality images, limited invasivity and a good safety profile. Nevertheless, the main limitation of SBCE is the lack of any possible direct therapeutic intervention. Indications for SBCE have evolved throughout the years, from "old" ones such as suspected small bowel bleeding (still the main indication for SBCE) to newer ones such as refractory celiac disease, hereditary polyposis syndromes and Crohn's disease. Thus, nowadays SBCE has a key role in the diagnostic algorithms in many conditions. Furthermore, the introduction in the SBCE field of cutting-edge technologies, as artificial intelligence systems, is likely to shorten the reading time making SBCE even more effective and easy to perform. Preliminary data are extremely promising and solid evidence is being gathered by current studies.

Abstract
Wireless capsule endoscopy (WCE) has revolutionized the capacity for evaluation of the gastrointestinal (GI) tract, but its evaluation is limited to the mucosal surface. To overcome this, ultrasound capsule endoscopy (UCE) that can evaluate the deeper structures beyond the mucosal surface has been proposed and several studies focusing on technology development have demonstrated promising results. However, investigations of the potential for clinical utility of this technology are lacking. This work had two main goals: perform ex vivo and in vivo imaging studies in a swine model to (1) evaluate if acoustic coupling between a capsule with a specific size and GI tract can be achieved only through peristalsis autonomously without any human control and (2) identify key issues and challenges to help guide further research. The images acquired in these studies were able to visualize the wall of the GI tract as well as the structures within demonstrating that achieving adequate acoustic coupling through peristalsis is possible. Critical challenges were identified including level of visualization and area of coverage; these require further in-depth investigation before potential clinical utility of UCE technology can be concluded.

Magnetic Resonance Enterography and Capsule Endoscopy in Patients Undergoing Patency Capsule for the Evaluation of Small Bowel Crohn's Disease: A Korean Clinical Experience. Gastroenterol Res Pract 2020; 2020:8129525. [PMID: 32328099 PMCID: PMC7160711 DOI: 10.1155/2020/8129525] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 02/24/2020] [Accepted: 02/28/2020] [Indexed: 12/21/2022] Open
Abstract
Objective Studies comparing magnetic resonance enterography (MRE) and capsule endoscopy (CE) for the assessment of small bowel (SB) Crohn's disease (CD) are scarce in Korea. In addition, there is no Korean experience of patency capsule (PC) examination prior to CE. The primary aim of this study was to compare diagnostic yields of MRE and CE for the assessment of SB CD. Secondary objectives were to compare the detection rate of proximal SB lesions by each modality in the Montreal classification and evaluate the safety and feasibility of PC in Korean CD patients. Methods MRE was performed as the first examination to assess SB CD. PC examination and CE were then performed. Diagnostic yields of active SB disease by MRE and CE were then analyzed. Results Disintegration of the patency capsule was shown in 5 patients out of 26 patients, who did not undergo CE. These 5 patients were accounted as negative CE findings. Overall, MRE and CE detected 80.8% and 65.4% of active SB lesions of CD in 26 patients, respectively (P = 0.212). MRE and CE detected 0% (0/26) and 19.2% (5/26) (P = 0.051) of jejunal lesions, 30.8% (8/26) and 42.3% (11/26) (P = 0.388) of proximal ileal lesions, and 80.8% (21/26) and 53.8% (14/26) (P = 0.039) of terminal ileal lesions, respectively. According to the Montreal classification, MRE and CE independently detected proximal disease (L4) in 30.8% (8/26) and 53.8% (14/26) (P = 0.092), respectively. Conclusions The diagnostic yields of MRE and CE for the assessment of SB CD including proximal SB lesions were similar. MRE is a more objective tool for detecting clinically relevant stricture than PC although PC examination could be performed safely before CE to prove the patency of SB. This trial is registered with KCT0004305.

Abstract
BACKGROUND Crohn's disease (CD) can be classified according to endoscopic and cross-sectional imaging characteristics. Information regarding disease extent and phenotype may be provided by advanced endoscopic and imaging techniques. In this study, we compare the ability of capsule endoscopy (CE) and cross-sectional imaging techniques (CST) (MRE/Computer Tomography Enteroscopy [CTE]) in detecting small bowel (SB) lesions. METHODS We retrospectively analyzed 102 patients with a diagnosis of CD who underwent both CE and CST. Only patients with at least a 12-month follow-up after CE were included. RESULTS Sensitivity and specificity for the detection of SB lesions were, respectively, 100% and 83.3% for CE, 55.1% and 80% for CTE, and 60% and 82.3% for MRE. CE detected proximal CD lesions in 73% of patients, whereas MRE and CTE detected proximal lesions in 41% and 16% of patients, respectively (P < 0.001). Positive findings on CE led to management changes in all patients, in a median follow-up period of 58.7 months. During the follow-up period, 26.5% of patients underwent surgery. Multivariate analysis revealed that moderate-to-severe disease at CE was independently correlated with surgery (P = 0.03). CONCLUSIONS CE has a superior sensitivity for detecting CD lesions in the proximal and medium SB compared with CST. In the terminal ileum, MRE and CTE displayed similar performance to CE.

Abstract
Background and aim: Capsule retention is the most common adverse event associated with video capsule endoscopy. The use of double-balloon enteroscopy-assisted capsule endoscope retrieval has been increasingly reported in recent years. However, evidence is limited regarding its success rate, associated factors, and subsequent clinical outcomes.Methods: A systematic review of relevant studies published before January 2019 was performed. Successful retrieval rate and associated factors, rate of endoscopic balloon dilation, and outcomes after double-balloon enteroscopy were summarized and pooled.Results: Within 154 associated original articles, 12 including 150 cases of capsule retrieval by double-balloon enteroscopy were included. The estimated pooled successful retrieval rate was 86.5% (95% confidence interval, 75.6-95.1%). Anterograde approach and capsules retained in the jejunum or trapped by malignant strictures were associated with a higher successful retrieval rate than the retrograde approach (62/83 [74.7%] vs. 10/38 [26.3%], p < .001) and capsules retained in the ileum (41/41 [100.0%] vs. 43/58 [74.1%], p < .001) or trapped by benign strictures (21/21 [100.0%] vs. 65/83 [78.3%], p = .043). Endoscopic balloon dilation was performed in 38.8% (95% confidence interval, 22.3-56.3%) of patients with benign strictures. Two perforations (1.3%) were reported as severe adverse events after double-balloon enteroscopy. A significantly lower surgery rate was found among cases with successful video capsule removal compared with unsuccessful cases (7.2% vs. 38.5%, p = .002).Conclusions: Double-balloon enteroscopy is feasible and safe for removing retained video capsule endoscopes, and its use could decrease the need for surgery in patients with benign strictures and facilitate subsequent surgery in patients with malignant strictures.

Abstract
BACKGROUND The main factor that limits wider utilization of capsule endoscopy (CE) in Crohn's disease (CD) is the potential risk of retention. The aim of this systematic review was to evaluate capsule retention rates in adult and pediatric CD and determine if retention risk is reduced in established CD (ECD) with patency capsule (PC) or magnetic resonance/computed tomography (MR/CT) enterography. METHODS Studies of CD patients undergoing CE that reported retention were identified. Pooled estimates for retention rates and relative risk in ECD to suspected CD (SCD) were calculated. All hypothesis tests were 2-sided; statistical significance was set at a P value of <0.05. RESULTS In the overall CD cohort, retention rates were 3.32% (95% confidence interval [CI], 2.62%-4.2%): 4.63% (95% CI, 3.42%-6.25%) and 2.35% (95% CI, 1.31%-4.19%) in ECD and SCD, respectively. Retention rates were 3.49% (95% CI, 2.73%-4.46%) and 1.64% (95% CI, 0.68%-3.89%) in adult and pediatric CD, respectively. Retention risk in adult ECD was 3.4 times higher than SCD, but there was no difference in retention risk in pediatric ECD compared with SCD. Retention rates in ECD were decreased after patency capsule (2.88%; 95% CI, 1.74%-4.74%) and MR/CT enterography (2.32%; 95% CI, 0.87%-6.03%). CONCLUSIONS In comparison with older literature, this meta-analysis demonstrates lower CE retention rates in SCD and ECD. Retention rates in pediatric CD were lower than in adult CD. Retention rates in adult ECD were higher than SCD, but there were no differences between pediatric ECD and SCD. Retention rates in ECD were lower after negative PC or MR/CT enterography.

Abstract
Background and Purpose Patency capsule (PC) examination is usually performed - previously to capsule endoscopy - to evaluate small-bowel patency in patients with established Crohn's disease (CD). The reported PC retention rate is significantly higher than expected. Our aims were to assess small-bowel patency, to determine the precise location of the retained PC in patients with CD, and to determine the false positive rate of evaluation with a radiofrequency identification tag (RFIT) scanner. Methods This is a prospective single-center study including CD patients with clinical indication for small-bowel capsule endoscopy. PillCam® PC examination was performed on all patients to assess small-bowel patency. On all patients with a positive identification of the PC using an RFIT scanner, 30 h after ingestion, an abdominal CT was performed in order to identify its precise location. Results Fifty-four patients were included. The PC retention rate, according to evaluation with the RFIT scanner, was 20% (in 11 patients) 30 h after ingestion. These patients were then submitted to abdominal CT, which revealed that there was small-bowel retention in 5 cases (9%). Higher CRP levels, penetrating disease, and a history of abdominal surgery were associated with an increased risk of PC retention (p = 0.007, p = 0.011, and p = 0.033, respectively). On multivariate analysis, there was an independent association between small-bowel PC retention and CRP levels >5 mg/dL (OR = 15.5; p = 0.03). Discussion The small-bowel PC retention rate (9%) was considerably lower than those found in previous reports. Our results show that, with this protocol, the false-positive cases of RFIT scans or plain abdominal X-rays may be avoided. This may contribute to more extensive application of capsule endoscopy without the risk of small-bowel retention.

Abstract
INTRODUCTION Video capsule endoscopy (VCE) is a useful tool to differentiate small intestinal bleeding, inflammatory bowel disease, and other small bowel disease. The most common adverse effect of VCE is capsule retention; the incidence varies greatly depending on the underlying disease, which is known to increase from 1.5% in healthy individuals to 21% in patients with small bowel Crohn disease. We report this case on a patient who had asymptomatic capsule retention for 12 months and experienced natural elimination with medication. PATIENT CONCERNS A 21-year-old woman presented to the hospital with chronic abdominal pain and persistent diarrhea for 2 years. DIAGNOSES The patient was diagnosed with small bowel Crohn disease using VCE, and radiography revealed capsule retention. INTERVENTION Symptoms of obstruction were not distinctive, it was decided to increase the dosages of azathioprine and infliximab to 50 and 500 mg (10 mg/kg), at 5 months after VCE. And at month 11 of capsule retention, she was admitted and started on a regimen of hydrocortisol 300 mg for 4 days and hydrocortisol injection 200 mg for 10 days. OUTCOMES At month 12, abdominal radiography in the clinic confirmed that the capsule had been naturally retrieved. LESSONS Capsule retention could be initially treated conservatively with medication and if the treatment fails, it is recommended to remove the capsule surgically. But in the case of the clinical condition of the patient is favorable without symptoms of bowel obstruction, the medication should be continued and the patient followed up.

Abstract
BACKGROUND The European Society of Gastrointestinal Endoscopy (ESGE) has recently issued a technical review focused on small bowel capsule endoscopy (SBCE). AIM To compare SBCE current practice in Italy to ESGE technical recommendations. MATERIAL AND METHODS A dedicated per-centre semi-quantitative questionnaire was prepared by a group of SBCE experts. One-hundred-fifty Centres were invited to participate in the data collection concerning SBCEs performed between June 2016 and June 2017. Data were compared with ESGE recommendations. RESULTS 120 Centres participated in the data collection. Current practices agreed with ESGE recommendations in 56.3% (9/16) of the issues evaluated. Differences between ESGE recommendations and current practice concerned the management of patients with pacemakers or cardiac implantable defibrillators (which was in agreement with ESGE recommendations in 31.7% and 15.8% of Centres, respectively), the SBCE setting (only 51% of SBCEs were performed as outpatients procedures), the assessment of capsule excretion (timing and modality were in agreement with ESGE recommendation in 20.0% of Centres), and in the involvement of trained nurses or fellows in training as pre-readers (7/120; 5.8%). CONCLUSIONS Although SBCE is widely used and largely available in Italy, there are still some technical, practical and organizational issues that can be modified to bridge the gap between current practice and ESGE guideline recommendations.

Abstract
Background/aims: The key procedure-related risk with video capsule endoscopy (VCE) is capsule retention, which should be suspected in patients who have not reported capsule passage. The study aims were to determine the frequency of capsule passage visualization and the difference in self-reporting of capsule passage between patients who receive patient-oriented education (POE) and patients who receive POE and a visual aid intervention in the form of a wrist band (WB). Methods: This was a prospective randomized study that enrolled patients undergoing VCE. Patients were randomly assigned to a POE group versus a POE and WB group. POE consisted of verbal education and an information booklet. Both groups received instructions to notify the study team regarding capsule passage. Results: Sixty patients (mean age 57 ± 18 years; 61% female) were included. A total of 57 patients were included in the analysis (3 lost to follow-up; 28 in POE group; 29 in WB group). Capsule passage status was reported by 68% without significant difference between POE and WB groups (72% vs. 64%; p = .51). Capsule passage status was obtained from all 57 patients with the addition of a proactive follow-up. Only 56% (n = 32) reported visualizing capsule passage. Of the remaining patients who did not visualize capsule passage, 60% (n = 15) reported on this without significant difference between the POE and WB groups (p = .23). Conclusions: Lack of visualization of capsule passage is a poor indicator of retention. Self-reporting of VCE passage status is suboptimal and the addition of a visual aid did not improve this parameter.

Abstract
PURPOSE OF REVIEW The review discusses the roles of small bowel capsule endoscopy and deep enteroscopy in patients with Crohn's disease. It highlights recent advances in the field and identifies areas where evidence is lacking. RECENT FINDINGS Small bowel capsule endoscopy has an important role in the follow-up of patients with Crohn's disease after escalation of therapy and in the postoperative assessment period following surgical resection. Device-assisted enteroscopy offers the therapeutic advantage of small bowel dilatation, which may result in a reduction in the number of surgical resections required, thus avoiding long-term complications, such as short bowel syndrome and malabsorption. SUMMARY Capsule endoscopy has an established role in the diagnosis and management of small bowel Crohn's disease. It is used in the setting of suspected Crohn's disease when ileocolonoscopy is negative and for the assessment of extent of small bowel disease in established Crohn's disease. It is relatively well tolerated because of the provision of patency capsule endoscopy to minimize the risk of inadvertent capsule retention. Device-assisted enteroscopy aids with the diagnosis of Crohn's disease as it enables histology to be taken from inflamed areas within the small bowel. Therapeutic procedures can be carried out during device-assisted enteroscopy including dilatation of Crohn's disease-related strictures and retrieval of retained capsules.

Abstract
The patency capsule is a radiopaque, dissolvable diagnostic tool, similar in shape and size to small bowel capsule endoscopes. It was developed to offer a simple, safe, efficient, and accurate evaluation of small bowel functional patency. Although unable to provide direct visual information regarding the presence and location of strictures, masses, or luminal narrowing of the small bowel, a successful patency test minimizes the risk of retention and allows the safe administration of a capsule endoscope. However, its use entails a low risk of potentially harmful adverse events, which in their majority are indolent and resolve spontaneously. Abdominal pain and symptomatic retention are accountable for the majority of reported adverse events, whereas a limited number of reports describe life-threatening complications, namely intestinal obstruction, perforation, and intestinal ischemia. Computed tomography is the modality of choice for the identification of the exact position of an impacted patency capsule, whilst the use of plain abdominal radiographs should be avoided for the evaluation of the patency capsule position, as they provide false information. Hereby, we present a comprehensive review of the available literature regarding the characteristics, indications, clinical use, effectiveness, and adverse events of the patency capsule.10.1093/ibd/izy152_video1izy152.video15777752348001.

Abstract
Capsule endoscopy (CE) is commonly used for examining and diagnosing gastrointestinal disease, especially small bowel disease. Capsule retention is a well-known and significant complication of CE and requires surgical or endoscopic removal. Most reports described the retrieval of retained CE via laparotomy. We report a case of successful retrieval of the capsule using laparoscopic surgery.

Abstract
Capsule endoscopy (CE) has proved to be an important non-invasive tool for diagnosis and monitoring Crohn’s disease patients. It has the advantage of excellent visualization of digestive tract mucosa, a good tolerability and safety in well-selected patients. The risk of retention can be diminished by good selection of patients using imaging techniques and by the use of patency capsule. The aim of a capsule examination is not only an early diagnosis but also a very good stratification of prognosis, thus directing the treatment strategy for either a step up or top-down approach and also permitting the optimization of the treatment depending on the findings. When symptoms and biomarkers point to a change in the disease’s activity we can either adjust the treatment directly as recommended in CALM study or choose in selected patients to visualize the digestive mucosa through a CE and take a decision afterwards. The appearance of the new capsule from Medtronic-the Pillcam Crohn’s might be an important step forward in diagnosis, evaluating disease extent, the severity of the disease, prognosis, management in a treat to target approach, with treatment modifications according to the data from CE examination. Serial examinations in the same patient can be compared and a more objective evaluation of the lesions modification from one exam to another can be performed. We present the latest developments and current status and evidence that in selected patients capsule can be a tool in a treat to target approach.

Abstract
Small bowel capsule endoscopy is considered a first-line diagnostic tool for the investigation of small bowel diseases. Gastroenterological and endoscopic societies have proposed and established measures known as quality indicators, quality measures or performance measures for the majority of endoscopic procedures, in order to ensure competence, healthcare quality and define areas requiring improvement. However, there is a paucity of publications describing small bowel capsule endoscopy quality indicators. Hereby, we attempt to identify and describe a number of pre-procedure, intra-procedure and post-procedure quality indicators, regarding process measures in small bowel capsule endoscopy, after a comprehensive review of the literature.
