Abstract
Capsule retention is one of the major complications of capsule endoscopy, which range from 2.1 to 8.2% depending on the indication. Over the last few years, reported rates of retention have fallen due to better patient selection due to the recognition of risk factors for capsule retention as well as the introduction of the patency capsule. The patency capsule is a dissolvable capsule with the same dimensions as the functional capsule. It breaks down in the GI tract after approximately 30 h, reducing the risk of symptomatic retention. Failure to pass this patency capsule out of the small bowel results in the patient being excluded from capsule endoscopy. We performed a retrospective analysis of the patency capsules performed in our unit over a 12-month period. A total of 166 (14.7%) of 1,127 patients referred for capsule endoscopy were deemed to require patency assessment (45.8% men, mean age 48 years). Of those who passed the patency assessment and underwent capsule endoscopy, no capsule retention was seen. Indication for patency assessment was found to be appropriate in 87.0% (n = 147). Overall, the failure rate at the patency assessment was 43.1%. The patency capsule remains an imperfect but useful tool in examining functional patency of the GI tract prior to capsule endoscopy.

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
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
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
BACKGROUND AND AIM The usefulness of a radio-tag-free PillCam patency capsule (PatCap) has been reported to evaluate the patency of the small intestine. If the PatCap is not excreted within 33 h, the location of the failed PatCap must be confirmed. Although several methods for locating the failed PatCap have been reported, a universal method has not been established. In this study, we aimed to confirm the clinical feasibility of abdominal ultrasonography combined with abdominal X-ray in the determination of the location of a failed PatCap. PATIENTS AND METHODS Consecutive patients who were scheduled to undergo the capsule endoscopy and had received PatCap examination between July 2012 and September 2019 were retrospectively analyzed. Failed PatCap was assessed using ultrasonography combined with abdominal X-ray. RESULTS Among the eligible 250 patients, 129 retrieved the PatCap in their stool within 33 h after ingestion. Among the remaining 121 patients, abdominal X-ray was performed and the PatCaps were suspected to be in the small bowel in 57 patients. Among these 57 patients, abdominal ultrasonography identified 17 PatCaps in the small bowel. Among the selected 250 patients, 233 patients (93.2%) were eligible for capsule endoscopy examination, while 17 patients (6.8%) were not eligible. Capsule endoscopy passed through the small intestine without any incident. CONCLUSION We confirmed that the abdominal ultrasonography with a radiographic targeting of the PatCap location is a reliable indicator to avoid the risk of capsule endoscopy retention or impaction and can be performed in most hospitals and clinics.

Abstract
Patency capsule (PC) can evaluate the patency of gastrointestinal (GI) tract. We hypothesized preceding patient selection using PC would improve the successful rate of colon capsule endoscopy (CCE). Therefore, a prospective single-arm study using PC followed by CCE was conducted with a control group of CCE alone. Patients with suspected or known GI stenosis scheduled for CCE were enrolled. CCE was performed only when the PC was excreted out of the body within 33 hours of ingestion. Primary endpoint was the rate of observation of the entire GI tract within the duration of examination. The secondary endpoints were complications and CCE findings. Twenty-three patients (17 men) were enrolled. The mean age was 50.5±19.8 years. Suspected stenotic sites were 8, 5, and 10 in the small, large, and small and large bowel, respectively. Sixteen, 12, and 10 patients had abdominal pain, active inflammatory bowel disease, and history of surgery for suspected stenosis, respectively. Patency of GI tract was confirmed in 96% (22/23) of the patients by administered PC. Of the 22 patients who underwent CCE, the entire GI tract was observed in 86% (19/22). No complications were observed. The median transit times in the small bowel and colon were 99 (21–682) and 160 (5–328) minutes, respectively. CCE findings revealed ulcers, erosions, and diverticula in 5, 9, and 4 patients, respectively. In conclusion, CCE with PC might be a safer and useful modality to observe the large colon for patients with suspected GI stenosis.

Abstract
Video capsule endoscopy is indicated in a broad range of clinical settings, most commonly in evaluating suspected small bowel bleeding. It is also useful in diagnosing Crohn's disease and monitoring patients with known Crohn's. Video capsule endoscopy has a role in evaluating patients with refractory celiac disease symptoms and in surveying patients with polyposis syndromes. The only absolute contraindication to video capsule endoscopy is luminal gastrointestinal tract obstruction. Despite manufacturer statement, video capsule endoscopy can be used safely in patients with implantable cardiac devices including pacemakers, defibrillators, and ventricular assist devices.

Abstract
BACKGROUND Predictors besides symptoms of obstruction indicating small bowel stenosis are little known. AIMS To detect predictors of small bowel stenosis in balloon-assisted enteroscopy. METHODS Over a 6-year period, 461 patients had enteroscopy for suspected small intestinal disease. Details of clinical manifestations, medical history, demographic characteristics, findings of examinations, information on enteroscopy, and treatment were retrospectively collected based on medical records. Small bowel stenosis was defined as stricture that over-tube cannot go through in enteroscopy. Univariate and multivariate analyses were performed to identify predictors for small bowel stenosis. RESULTS A total of 314 patients had definite diagnosis after enteroscopy, imaging modalities, and/or even surgical exploration. They were included in this study for analyses. Mean age for them was 48.2 years old (range 15-81 years). Small bowel stenosis was present in 59 patients (18.8%). Analyses showed that CT/MRI indicating stenosis was significantly associated with severe stenosis (p = 0.014) but insignificant related to general stenosis (p = 0.097). Predictive factors that accompanied stenosis were age ≥ 60 years (OR = 2.1, 95% CI 1.1-4.0), underweight (BMI ≤ 18.5) (OR = 3.4, 95% CI 1.4-8.4), symptoms of obstruction (OR = 3.6, 95% CI 1.8-7.4), and overt small bowel bleeding (OR = 0.5, 95% CI 0.2-0.9). CONCLUSIONS Small bowel stenosis more tended to occur to patients with symptoms of obstruction, no overt small bowel bleeding, age ≥ 60 years, or underweight.

Abstract
Lower gastrointestinal endoscopy has evolved over time, fulfilling a widening diagnostic and therapeutic remit. As our understanding of colorectal cancer and its prevention has improved, endoscopy has progressed with improved diagnostic technologies and advancing endoscopic therapies. Despite this, the fundamental design of the endoscope has remained similar since its inception. This review presents the important role lower gastrointestinal endoscopy serves in the prevention of colorectal cancer and the desirable characteristics of the endoscope that would enhance this. A brief history of the endoscope is presented. Current and future robotic endoscopic platforms, which may fulfil these desirable characteristics, are discussed. The incorporation of new technologies from allied scientific disciplines will help the endoscope fulfil its maximum potential in preventing the increasing global burden of colorectal cancer. There are a number of endoscopic platforms under development, which show significant promise.

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
BACKGROUND The most concerning complication of capsule endoscopy (CE) is capsule retention (CR) in the gastrointestinal (GI) tract; however, the clinical outcomes and management of patients with CR are still uncertain. AIMS This study aimed to investigate the clinical outcomes and management of CR. METHODS The outcomes of CR in multiple centers between October 2002 and June 2018 were retrospectively reviewed. Data on CE indication, findings, and management details were analyzed. RESULTS A total of 2705 consecutive small-bowel CE procedures were performed. CR was detected in 20 cases (0.7%). The most common site of CR was the small bowel (19 cases), followed by the esophagus (one case). In patients who underwent CE, CR was detected in nine (0.6%) of 1397 patients with obscure GI bleeding. Further, CR occurred in 11 (6.5%) of 169 patients with Crohn's disease based on the final diagnoses after CE. Capsule retrieval was safely performed surgically in nine cases and endoscopically in six cases. The retained capsules dislodged after steroid treatment in two cases, whereas three cases of CR resolved without any intervention. In multivariate analysis, the development of abdominal symptoms after CR was a significant predictive factor for requiring endoscopic or surgical interventions for capsule extraction. CONCLUSIONS This large multicenter study shows that CR is a rare complication with favorable clinical outcomes. Three-fourths of the patients with CR were managed with endoscopic or surgical intervention, which was required particularly in patients with abdominal symptoms after CR.

Abstract
Small-bowel capsule endoscopy (SBCE) is used widely because of its non-invasive and patient-friendly nature. SBCE can visualize entire small-intestinal mucosa and facilitate detection of small-intestinal abnormalities. In this review article, we focus on the current status of SBCE. Several platforms for SBCE are available worldwide. Third-generation SBCE (PillCam® SB3) has a high-resolution camera equipped with an adaptive frame rate system. Several software modes have been developed to reduce the reading time for capsule endoscopy and to minimize the possibility of missing lesions. The main complication of SBCE is capsule retention. Thus, the main contraindication for SBCE is known or suspected gastrointestinal obstruction unless intestinal patency is proven. Possible indications for SBCE are obscure gastrointestinal bleeding, Crohn's disease, small-intestinal polyps and tumors, and celiac disease. Colon capsule endoscopy (CCE) can observe inflamed colonic mucosa non-invasively, and allows for the continuous and non-invasive observation of the entire intestinal tract (pan-endoscopy). Recently, application of CCE as pan-enteric endoscopy for inflammatory bowel diseases (including Crohn's disease) has been reported. In the near future, reading for CE will be assisted by artificial intelligence, and reading CE videos for long periods will not be required.

Abstract
The Asia-Pacific Working Group on Inflammatory Bowel Disease was established in Cebu, Philippines, under the auspices of the Asia-Pacific Association of Gastroenterology with the goal of improving inflammatory bowel disease care in Asia. This consensus is carried out in collaboration with Asian Organization for Crohn's and Colitis. With biologic agents and biosimilars becoming more established, it is necessary to conduct a review on existing literature and establish a consensus on when and how to introduce biologic agents and biosimilars in conjunction with conventional treatments for ulcerative colitis and Crohn's disease in Asia. These statements also address how pharmacogenetics influences the treatments of ulcerative colitis and Crohn's disease and provides guidance on response monitoring and strategies to restore loss of response. Finally, the review includes statements on how to manage treatment alongside possible hepatitis B and tuberculosis infections, both common in Asia. These statements have been prepared and voted upon by members of inflammatory bowel disease workgroup employing the modified Delphi process. These statements do not intend to be all-encompassing, and future revisions are likely as new data continue to emerge.

Frontline Gastroenterol 2019; 10:217-221.

Abstract
BACKGROUND The main risk of capsule endoscopy is retention of the capsule behind a stricture. Passage of an intact Agile patency device (Medtronic, Dublin, Ireland) through the small bowel is widely used to ensure luminal patency, although capsule retention has occurred in patients who have had a reassuring patency study. The device is designed to remain intact for at least 30 hours postingestion, such that loss of signal from the radiofrequency identification tag contained within, or absence of the device on radiological imaging, implies unimpeded intestinal transit. AIM To identify the rate of premature dissolution (<30 hours postingestion) of the Agile patency device. METHODS Outcomes of all consecutive patients having an Agile patency device were analysed. RESULTS Premature dissolution of the patency device occurred in 5 of 307 patients, an incidence of 1.3%. This was recognised by the detection of a persistent radiofrequency signal after radiological imaging had failed to identify the patency device, prompting a careful search for the radiofrequency tag on the CT scout film. The tag was difficult to detect because of an oblique lie making it appear smaller than its 13×3 mm size and confusion with intra-abdominal or other metallic fragments. CONCLUSIONS In the absence of radiological evidence of an intact Agile patency device, premature dissolution should be suspected in patients registering a persistent radiofrequency signal and confirmed by identifying the radiofrequency identification tag. Failure to do so might result in false reassurance that capsule endoscopy could be performed without risk of retention.

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
Environmental enteric dysfunction (EED) is a disease of the small intestine affecting children and adults in low and middle income countries. Arising as a consequence of repeated infections, gut inflammation results in impaired intestinal absorptive and barrier function, leading to poor nutrient uptake and ultimately to stunting and other developmental limitations. Progress towards new biomarkers and interventions for EED is hampered by the practical and ethical difficulties of cross-validation with the gold standard of biopsy and histology. Optical biopsy techniques - which can provide minimally invasive or noninvasive alternatives to biopsy - could offer other routes to validation and could potentially be used as point-of-care tests among the general population. This Consensus Statement identifies and reviews the most promising candidate optical biopsy technologies for applications in EED, critically assesses them against criteria identified for successful deployment in developing world settings, and proposes further lines of enquiry. Importantly, many of the techniques discussed could also be adapted to monitor the impaired intestinal barrier in other settings such as IBD, autoimmune enteropathies, coeliac disease, graft-versus-host disease, small intestinal transplantation or critical care.

Abstract
BACKGROUND A patency capsule (PC) can help predict capsule endoscope (CE) retention; however, PC tolerability is unknown in children. We retrospectively evaluated PC tolerability in school-aged children. METHODS Sixty-one patients (median age, 12.9 years; range 7.4-17.3 years) who underwent PC examination were analyzed for occurrence and determinants of ingestion difficulty and relationships between ingestion of the 2 capsules. We defined ingestion difficulty as taking 30 min or more, or failure, to ingest the PC. RESULTS Thirty-nine patients (64%) successfully ingested the PC without ingestion difficulty. The other 22 had ingestion difficulty and were significantly younger (11.7 ± 2.2 vs. 13.0 ± 1.8 years; p = 0.04) and shorter (143.3 ± 14.0 vs. 154.6 ± 12.5 cm; p = 0.003) than those without ingestion difficulty. Multivariate analysis showed that the most significant factor for predicting PC ingestion difficulty was height (cutoff value, 152 cm). Time to ingest the CE was significantly shorter than that for PC ingestion (8 ± 32 vs. 20 ± 58 min; p = 0.01). All patients indicated that ingestion of the CE was easier because of its smooth surface compared with the PC. CONCLUSIONS PC ingestion is not guaranteed in school-aged children. PC ingestion ability should be evaluated by considering the child's height and lack of experience ingesting capsules prior to PC examination.

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.

Abstract
We present an unusual case of a 35-year-old male patient whom a patency capsule stayed in his gut without breaking. He has a history of Peutz-Jeghers syndrome and multiple abdominal surgeries. Prestudy was performed for abdominal searching, but a patency capsule remained in the colon over 9 days. He displayed neither abdominal nor obstructive symptoms in that period. We collected the patency capsule using colonoscopy after dilating a postoperative stricture at an anastomotic site of the rectum. Clinicians should bear in mind that patency capsules may become retained as distally as the colon in patients with a surgical history of the large intestine.

Abstract
BACKGROUND Patency capsule was developed to avoid small bowel video capsule endoscopy retention, namely in patients with Crohn's disease. AIMS To evaluate the predictive factors of small bowel patency in Crohn's disease patients. PATIENTS AND METHODS Retrospective analysis including 151 Crohn's disease patients submitted to patency capsule (Agile® Patency Capsule) from 2011 to 2012. Patients that excreted the intact patency capsule were classified as having a patent small bowel (without patency capsule retention), other patients were considered to have negative patency of the small bowel (patency capsule retention). RESULTS Patients had a mean age of 41±14 years, 54% were female and 25% had been previously submitted to surgery. Stricturing disease was seen in 20% of cases and penetrating disease in 16% of cases. Left-sided colonic lesions and ileal strictures were observed at colonoscopy in 13% and 9% of patients, respectively. In our sample, 28% of patients had negative patency of the small bowel (patency capsule retention). In multivariate analysis, independent factors that were associated with negative patency of the small bowel in Crohn's disease patients were stricturing (OR 10.16, p < 0.001) and penetrating phenotypes (OR 11.73, p = 0.001), left-sided colonic lesions (OR 3.77, p = 0.038), ileal stricture (OR 9.76, p = 0.003); previous intestinal surgery was found to be protective (OR 0.16, p = 0.006). CONCLUSIONS Stricturing or penetrating disease, ileal strictures, no previous surgery and left-sided colonic lesions were the factors associated with negative small bowel patency in Crohn's disease patients.

Abstract
BACKGROUND & AIMS Video capsule endoscopy (CE) provides a noninvasive option to assess the small intestine, but its use with respect to endoscopic procedures and cross-sectional imaging varies widely. The aim of this consensus was to provide guidance on the appropriate use of CE in clinical practice. METHODS A systematic literature search identified studies on the use of CE in patients with Crohn's disease, celiac disease, gastrointestinal bleeding, and anemia. The quality of evidence and strength of recommendations were rated using the Grading of Recommendation Assessment, Development, and Evaluation (GRADE) approach. RESULTS The consensus includes 21 statements focused on the use of small-bowel CE and colon capsule endoscopy. CE was recommended for patients with suspected, known, or relapsed Crohn's disease when ileocolonoscopy and imaging studies were negative if it was imperative to know whether active Crohn's disease was present in the small bowel. It was not recommended in patients with chronic abdominal pain or diarrhea, in whom there was no evidence of abnormal biomarkers typically associated with Crohn's disease. CE was recommended to assess patients with celiac disease who have unexplained symptoms despite appropriate treatment, but not to make the diagnosis. In patients with overt gastrointestinal bleeding, and negative findings on esophagogastroduodenoscopy and colonoscopy, CE should be performed as soon as possible. CE was recommended only in selected patients with unexplained, mild, chronic iron-deficiency anemia. CE was suggested for surveillance in patients with polyposis syndromes or other small-bowel cancers, who required small-bowel studies. Colon capsule endoscopy should not be substituted routinely for colonoscopy. Patients should be made aware of the potential risks of CE including a failed procedure, capsule retention, or a missed lesion. Finally, standardized criteria for training and reporting in CE should be defined. CONCLUSIONS CE generally should be considered a complementary test in patients with gastrointestinal bleeding, Crohn's disease, or celiac disease, who have had negative or inconclusive endoscopic or imaging studies.

Abstract
INTRODUCTION Capsule endoscopy (CE) has become a first-line tool for small bowel (SB) examination. However, adverse events (AEs), such as CE retention or aspiration, may occur. The aims of this study were to evaluate incidence, clinical outcomes and therapeutic approaches of CE-related AEs in the largest series published to date. METHODS Data from 5428 procedures performed at 12 institutions between August 2001 and January 2012 were retrospectively analyzed. Baseline patient characteristics; procedure; type, localization and symptoms before/after AEs; previous patency tests performed; therapeutic management and patient's outcome were recorded. RESULTS The overall incidence of CE-related AEs was 1.9%: 2.0% for SB, 0.9% for esophageal and 0.5% for colon CE. The incidence of capsule retention was significantly higher than capsule aspiration (1.87% vs. 0.003%; p < 0.05), in patients suffering from inflammatory bowel disease (IBD) than in obscure GI bleeding (OGIB) (3.3% vs. 1.5%; p < 0.05) and in patients with the combination of nausea/vomiting, abdominal pain and distension. The SB was the most frequent localization of retention (88.2%). The use of patency tests -except for Patency© capsule- before CE was not a good predictor for AEs. Most of the patients with AEs developed no or mild symptoms (97%) and were managed by non-surgical methods (64.4%). CONCLUSIONS CE-related AEs are uncommon and difficult to predict by imagiological examinations. SB retention, that is usually asymptomatic, is the most frequent AE. In absence of symptoms, non-surgical management of CE-related AEs is recommended.

Abstract
Capsule endoscopy (CE) currently plays an important role in Crohn’s disease (CD). It is a noninvasive technique that has led to a breakthrough in the endoscopic diagnosis of diseases of the small intestine. Its superior diagnostic performance and excellent safety profile lead to its considerable acceptance on the part of the patient. This paper reviews current indications of CE in three stages of clinical practice: Suspected CD, unclassified colitis and its extensive role in diagnosed CD. The diagnostic and therapeutic impact of the results of CE on the monitoring of this disease is also reviewed. Knowledge of its applications, the interpretation of its results in an appropriate context and the existence of a validated endoscopic activity index could change the way in which these patients are managed. The definition of mucosal healing and postoperative recurrence by means of endoscopic scoring systems will endow CE with new applications in the management of CD in the near future.

Abstract
BACKGROUND AND AIMS The patency capsule is designed to evaluate the patency of the small bowel before administration of small-bowel capsule endoscopy (SBCE) in patients at high risk of retention. The utilization of a patency capsule may be associated with a risk of symptomatic retention, but very few cases have been reported to date. The aim of our study was to describe our experience with this rare complication of a patency capsule. METHODS This was a multicenter retrospective case series. The medical records of patients who underwent a patency capsule test were scanned and all cases of symptomatic retention were collected. RESULTS In total, 20 symptomatic cases of retention out of 1615 (1.2 %) patency capsule tests were identified; in one patient, the patency capsule was retained in the esophagus, in the rest, the capsule was detected in the small bowel resulting in abdominal pain or small-bowel obstruction. One patient (5 %) required surgery; all other patients resolved spontaneously or after corticosteroid therapy. CONCLUSIONS Symptomatic patency capsule retention is a very rare complication with a favorable prognosis. It should be recognized but its use in patients with suspected small-bowel stenosis should not be discouraged.

Abstract
BACKGROUND AND AIMS Both Agile patency capsule (PC) and small-bowel cross-sectional imaging (SBCSI) techniques have been used to assess small-bowel patency in patients at high risk of capsule retention. The present study aimed to compare capsule retention rates in high-risk patients with negative PC or SBCSI. MATERIALS AND METHODS Between January 2011 and December 2013, consecutive patients undergoing small-bowel capsule endoscopy (SBCE) in the Lombardia region were prospectively entered into a dedicated registry. They were classified as being at high or low risk of capsule retention by the local investigator according to predefined clinical criteria. High-risk patients underwent either PC or SBCSI depending on local expertise and availability; those who tested negative underwent SBCE. RESULTS Out of 3117 patients (male/female: 1667/1450, mean age: 63.1±17.7), 2942 (94.4%) were classified as being at low risk and 175 (5.6%) were classified as being at high risk for capsule retention. Among 175 high-risk patients, 151 (86.3%) had negative PC and 24 (13.7%) had negative SBCSI: capsule retention occurred in two patients with negative SBCSI (8.3%) and in one patient (0.7%) with negative PC (P=0.049). The capsule retention rates in high-risk patients with negative PC and in low-risk patients (20/2942; 0.7%) were comparable (P=1.0). CONCLUSION The capsule retention rate is similar in low-risk and negative PC high-risk patients. Conversely, high-risk patients with negative SBCSI have a significantly higher capsule retention rate. Our data suggest that in high-risk patients, negative SBCSI examination is not reassuring and, when SBCE is indicated, PC should be performed.

Abstract
Endoscopy has a crucial role in the diagnosis, management, and surveillance of inflammatory bowel disease (IBD). It contributes in supporting the diagnosis of IBD with the clinical history, physical examination, laboratory findings, and targeted biopsies. Furthermore, endoscopy has a significant role in assessing disease activity and distribution in treatment efficacy evaluation, post-surgical recurrence risk, and cancer surveillance in patients with long-lasting illness. Endoscopy also provides therapeutic potential for the treatment of IBD, especially with stricture dilatation and treatment of bleeding. Small bowel (SB) endoscopy (capsule endoscopy and device-assisted enteroscopy) and cross-sectional radiologic imaging (computed tomography enterography and magnetic resonance enterography) have become important diagnostic options to diagnose and treat patients with SB Crohn's disease. We reviewed the present role of SB endoscopy in patients with SB Crohn's disease.

Abstract
BACKGROUND/AIMS A patency capsule (PC) is used to assess intestinal patency in patients with known or suspected stricture, but PC localization by plain abdominal X-ray (AXR) is difficult in those patients in whom the PC is not detected in the feces. Tomosynthesis is a promising, cost-effective, and low-radiation digital tomographic technique. This prospective study evaluated its use for PC localization in the intestinal tract. METHODS The study subjects were 49 patients in whom the PC was not detected in the feces and was identified intra-abdominally on AXR films. PC localization in the small or large intestines by AXR alone or by tomosynthesis with AXR was compared with abdominal computed tomography (CT), which is the gold standard. RESULTS The PC was judged in the large and small intestines in 22 and 27 patients by AXR alone versus 34 and 15 patients, respectively, by tomosynthesis combined with AXR. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for PC detection by AXR alone were 52.9, 53.3, 56.2, 50.0, and 53.1%, respectively. The same parameters were 100, 100, 100, 100, and 100%, respectively, for tomosynthesis with AXR, which were identical to those of CT. CONCLUSIONS Tomosynthesis with AXR is superior to AXR alone, though similar to CT, with respect to localization of the PC.

Abstract
OBJECTIVE Patency capsule (PC) examination has made it possible to perform capsule endoscopy (CE) in patients with a suspected small-bowel stricture. However, PC has some drawbacks, so we assessed the usefulness of transabdominal ultrasonography (TUS) prior to PC in patients with suspected small-bowel strictures to avoid unnecessary PC examination. PATIENTS AND METHODS Fifty-two patients who underwent TUS prior to PC were enrolled in this study. TUS findings were classified as follows: intestinal narrowing and distension at the oral side (Type A); extensive bowel wall thickening (Type B); focal bowel wall thickening (Type C) or no abnormality detected (Type D). We evaluated the TUS and PC findings for the detection of small-bowel strictures. RESULTS Double-balloon endoscopy (DBE) revealed small-bowel strictures in 13 of 50 patients (26%). TUS yielded Type B or C findings in 12 of 13 patients (92%), while PC revealed strictures in all 13 patients. In Crohn's disease (CD) patients with Type B TUS findings, 8 of 9 (89%) had small-bowel strictures on DBE. However, only two of six non-CD patients (33%) with Type B TUS findings had small-bowel strictures. The incidence of Type B strictures was significantly higher in CD patients. CONCLUSIONS CD patients with Type B TUS findings should not undergo PC or CE because of the high rate of small-bowel strictures. Non-CD patients diagnosed with Type B TUS strictures, as well as patients diagnosed with Type C or D strictures should undergo CE after confirming small-bowel patency using PC.

Abstract
GOALS The aim is to elucidate the efficacy and safety of double-balloon endoscopy (DBE) for small bowel capsule endoscopy (SBCE) retrieval from small bowel stricture and to follow the outcome of the stricture where the SBCE was entrapped. BACKGROUND The retention of SBCE is a serious adverse event and most retained capsules are retrieved by surgery. There is still no report analyzing the follow-up of patients with stricture after retrieval of entrapped SBCEs by DBE. METHODS This study was designed a retrospective cohort study. Subjects were 12 consecutive patients with small bowel stricture where retrieval of entrapped SBCE was attempted using DBE. Success rate of the SBCE retrieval by DBE, surgical rate of the small bowel stricture, adverse events of DBE, and outcomes in the follow-up period were evaluated. RESULTS Diagnoses were Crohn's disease, nonsteroidal anti-inflammatory drugs-induced enteropathy, ischemic enteritis, and carcinoma in 8, 2, 1, and 1 patients, respectively. SBCE was successfully retrieved in 11 of the 12 patients (92%). No adverse events were encountered in all endoscopic procedures such as retrieval of SBCEs and dilation of the strictures. Nine of the 12 patients (75%) did not undergo surgical treatment for the stricture where SBCE was entrapped through the follow-up period (mean, 1675±847 d). CONCLUSIONS Retrieval of SBCEs using DBE was safe, had a high success rate, and was useful to evaluate the need for surgery. Seventy-five percent of patients with small bowel stricture where the SBCE was entrapped did not require surgery through approximately 5 years.

Abstract
Video capsule endoscopy has revolutionized our ability to visualize the small bowel mucosa. This modality is a valuable tool for the diagnosis of suspected small bowel Crohn's disease, and it is increasingly used for the monitoring of disease activity in patients with established small bowel Crohn's. The purpose of the current article was to review the literature pertaining to the utilization of capsule endoscopy in established Crohn's disease, for monitoring of mucosal healing, postoperative recurrence, disease classification, and other indications.

Abstract
BACKGROUND AND AIM Excretion of the patency capsule (PC) within a certain time frame may be used to demonstrate luminal patency prior to capsule endoscopy (CE). We aimed to determine how often further radiological imaging is needed to confirm luminal patency after PC, assess radiologists' ability to locate the PC on plain abdominal films, and evaluate the outcomes of a novel computed tomography (CT) protocol for PC localization. METHODS A study of the ability of radiologists to localize PC using plain abdominal films was performed. A novel protocol targeting a limited CT at the level of the PC identified on the "scout" film if retained 30 h post-ingestion was prospectively evaluated in 400 consecutive patients undergoing PC. RESULTS In a study of the confidence with which radiologists could localize the PC on plain films, radiologists preferred abdominal CT to localize PCs identified on plain films in 74% of cases. In a protocol based on the use of a PC and targeted, limited CT scan to confirm small bowel patency in those failing to excrete the PC 30 h post-ingestion, the sensitivity, specificity, positive, and negative predictive value were 99.4%, 90.0%, 99.7%, and 81.0%, respectively. Crohn's disease was the only statistically significant predictor associated with higher risk of luminal stricture (P=0.001) in post-hoc analysis. CONCLUSIONS Excretion of the PC 30 h post-ingestion reliably predicts safe CE passage. Plain abdominal radiology is unreliable and a scout film targeted, limited CT scan offers an accurate minimal radiation method of determining small bowel patency.

Abstract
BACKGROUND AND AIM The Agile patency capsule (PC; Given Imaging Ltd, Yoqneam, Israel) is used as a dummy prior to capsule endoscopy (CE) to avoid retention of the CE capsule. However, impaction of the PC's inner radio frequency identification (RFID) tag in a stricture could cause small-bowel ileus. Recently, the RFID tag-less PC was introduced into clinical practice. Herein, we aimed to retrospectively evaluate the usefulness of the tag-less PC. METHODS Of 154 patients who were scheduled to undergo CE, 100 consecutive patients (65%) who underwent PC evaluation were enrolled in the present study. Primary study end point was the retention rate of the CE capsule after successful passage of the PC. Secondary end point was analysis of the significant factors affecting the passage of the PC. RESULTS In total, 87 patients (87%) had bowel patency confirmed by PC evaluation. There was no capsule retention in any of these 87 patients during CE. Abnormal findings were obtained from 60 CE, and 41 patients received new or modified treatment. Multivariate analysis of factors related to the confirmation of patency demonstrated that stenosis on imaging was the most influential factor (P = 0.002, odds ratio 16.387). The results confirmed that passage of the PC depends on stenosis on imaging. CONCLUSIONS Use of the tag-less PC confirmed gastrointestinal tract patency for most of the patients who did not have stenosis on imaging and allowed estimation of the patency for patients who did have stenosis on imaging.

Abstract
BACKGROUND AND AIMS Small bowel capsule endoscopy (SBCE) may detect proximal small bowel lesions that have been previously missed by ileocolonoscopy and small bowel imaging in patients with known ileal and/or colonic Crohn's disease (CD). We aimed to evaluate whether the therapeutic management is influenced by SBCE findings. METHODS Retrospective single center study. Inclusion of consecutive patients with known non-stricturing and non-penetrating ileal and/or colonic CD, submitted to SBCE to evaluate disease extension and activity, with ≥ 1 year follow-up. Lesions were classified with the Lewis score (LS) as non-significant (LS<135), mild (135≤LS≤790), or moderate-to-severe (LS>790). Therapeutic changes were assessed three months after SBCE. RESULTS Fifty consecutive patients (35±13 years, 52% females) were included. At ileocolonoscopy, disease location was ileal (L1) in 60%, colonic (L2) in 10% and ileocolonic (L3) in 30% of the patients. In 33 patients (66%) SBCE detected significant proximal lesions previously missed by other modalities. The proportion of patients on thiopurines and/or biologics before SBCE was 2/50 (4%); this was significantly higher three months after SBCE, 15/50 (30%), p=0.023. Treatment with thiopurines and/or biologics was started more often in patients with proximal small bowel lesions [13/33 (39%) vs. 1/17 (6%), p=0.011, relative risk (RR) 6.5], particularly when severe (6%, 36% and 45% of patients with non-significant, mild and moderate-to-severe inflammation, respectively). CONCLUSIONS SBCE diagnoses previously undetected lesions and it influences therapeutic management of CD, triggering an earlier introduction of immunomodulators and/or biological therapy.

Abstract
BACKGROUND Mucosal healing is increasingly recognised as an important treatment goal in Crohn's disease (CD). Data from colonic disease shows improved long-term outcomes in patients achieving complete mucosal healing. Little is currently known of this with regard to ileitis which is increasingly diagnosed using capsule endoscopy (SBCE). This is the first study to prospectively assess mucosal healing and deep remission rates following 52 weeks of therapy in a cohort of symptomatic small bowel CD patients commencing immunomodulator or biologic therapy. METHODS Baseline demographics, quality of life questionnaires and Harvey Bradshaw Index were collected along with C-reactive protein & calprotectin. Capsule endoscopy Crohn's disease activity (CECDAI) index was used to assess ileitis severity. All parameters were reassessed at week 52. Results at baseline & week 52 were compared using univariate analysis, p < 0.05 considered significant. RESULTS In total, 108 capsule procedures were performed on 43 patients. Based on the CECDAI, 39 (90%) demonstrated active small bowel CD at baseline with 28 (65%) undergoing 52 week assessment. In total, 12 (42%) participants achieved complete mucosal healing and deep remission by 52 week assessment (p<0.0001 95% CI -0.62 to -0.22). Despite overall impressive mucosal healing rates, patients with strictures were less likely to demonstrate a decrease in CECDAI and were more likely to have symptoms. CONCLUSION In patients with active small bowel CD symptomatic and biochemical response to treatment appears to be mirrored by endoscopic remission in 42% of individuals. Strictures identified prior to therapy appear to be a poor indicator for success of treatment.

Abstract
BACKGROUND PillCam patency capsule (PC) is a novel and radiofrequency identification tag-free device that remains intact in the gastrointestinal tract for 30-33 h after ingestion and then disintegrates. The aim of this study was to determine the clinical relevance of PC combined with abdominal ultrasonography as a reliable indicator of functional patency. PATIENTS AND METHODS The study was prospective and PillCam PC was administered to consecutive patients with known or suspected small bowel strictures. PC was verified if it was excreted intact in 33 h after administration. Following excretion failure and radiograph detection in the pelvic cavity, ultrasonography was used to detect the PC in relation to the stricture. RESULTS The participants were 52 patients with known or suspected small bowel strictures (58% women, mean age 51 years, including 32 with or suspected Crohn's disease). Twenty-two patients (42.3%) retrieved PC in the stool within 33 h after ingestion. Radiograph identified the four PCs in the colon and eight were not observed. Ultrasonography precisely judged all 17 PCs retained including six PCs at the proximal side of small bowel stricture in the patients considered ineligible for capsule endoscopy (CE). In all eligible patients, CE passed through the small intestine without incident. CONCLUSION PillCam PC combined with ultrasonography before CE appears to be a reliable indicator of functional patency to predict and minimize the risk of impaction in suspected or even known cases with small bowel stricture.

Abstract
BACKGROUND The development of capsule technology has modified our approach to the diagnosis of gastrointestinal disease. The relatively rapid uptake of capsule endoscopy as an important clinical tool can be largely ascribed to a number of key factors, including the fact that it is a relatively easy examination to perform in an outpatient setting. It has been established as an integral part of the investigation pathway for obscure gastrointestinal bleeding and suspected small bowel Crohn's disease (CD). CURRENT USE OF CAPSULE ENDOSCOPY: Small bowel CD can be a challenging entity to diagnose. Capsule endoscopy has been shown to be both useful and safe in patients with both suspected and established small bowel CD. In suspected disease, capsule endoscopy has both a high diagnostic yield and negative predictive value. Capsule findings lead to changes in management in up to 73% of patients with established CD. However, while the technology appears capable of detecting subtle mucosal changes not readily apparent on alternate imaging modalities, the question of what actually constitutes small bowel CD as described by capsule is an issue that remains unresolved to date. Thus, capsule endoscopy is best utilised in tandem with advanced imaging and endoscopic techniques such as balloon- assisted enteroscopy. FUTURE DEVELOPMENTS The development of a capsule capable of viewing the colon coupled with improvements in image quality and battery life are likely to lead to the increasing uptake of this technology. In the future, 'interactive' capsules with the ability to view the entire gastrointestinal tract may be a reality.

Abstract
OBJECTIVE Patency capsule (PC) is a tool to screen the patency of the gastrointestinal (GI) tract. Capsule endoscopy can be performed after the patency is confirmed by the patency capsule. We aimed to estimate the diagnostic value of PC based on the existing trials. METHODS We searched PubMed, CENTRAL and EMBASE for studies that included patients with suspected small bowel stricture who were evaluated by both PC and a reference standard (following capsule endoscopy and/or surgical pathology and/or endoscopic findings) and who were eligible for inclusion. The quality of the eligible studies was assessed using the Quality Assessment for Diagnostic Accuracy Studies-2 criteria. Sensitivity, specificity, likelihood ratios and the area under the receiver operating characteristic curve (AUROC) were calculated. RESULTS Five studies including 203 patients fulfilled the eligibility criteria. The pooled data showed a PC sensitivity of 97% (95% CI 93-99%) and a specificity of 83% (95% CI 65-94%). The AUROC was 0.9557. CONCLUSIONS PC may be of diagnostic value in confirming the patency of the GI tract before capsule endoscopy. The routine use of PC might eliminate the contraindication of capsule endoscopy in many cases of intestinal obstruction.

Abstract
Videocapsule endoscopy (VCE) has revolutionized our ability to visualize the small bowel mucosa. This modality is a valuable tool for the diagnosis of obscure small bowel Crohn’s disease (CD), and can also be used for monitoring of disease activity in patients with established small-bowel CD, detection of complications such as obscure bleeding and neoplasms, evaluation of response to anti-inflammatory treatment and postoperative recurrence following small bowel resection. VCE could also be an important tool in the management of patients with unclassified inflammatory bowel disease, potentially resulting in reclassification of these patients as having CD. Reports on postoperative monitoring and evaluation of patients with ileal pouch-anal anastomosis who have developed pouchitis have recenty been published. Monitoring of colonic inflammatory activity in patients with ulcerative colitis using the recently developed colonic capsule has also been reported. Capsule endoscopy is associated with an excellent safety profile. Although retention risk is increased in patients with small bowel CD, this risk can be significanty decreased by a routine utilization of a dissolvable patency capsule preceding the ingestion of the diagnostic capsule. This paper contains an overview of the current and future clinical applications of capsule endoscopy in inflammatory bowel disease.

Abstract
Over the last decade, WCE has established itself as a valuable test for imaging the small intestine. It is a safe and relatively easy procedure to perform that can provide valuable information in the diagnosis of small-bowel conditions. Its applications still remain limited within the esophagus and colon. Future developments may include improving visualization within the esophagus and developing technologies that may allow manipulation of the capsule within the GI tract and biopsy capabilities.

Abstract
OBJECTIVE To assess the clinical usefulness of transabdominal ultrasonography (TUS) for detection of small-bowel stricture. PATIENTS AND METHODS Subjects were 796 patients undergoing double-balloon endoscopy (DBE), December 2003-October 2011. All underwent TUS prior to DBE. The TUS findings were classified by type as intestinal narrowing and distension at the oral side (Type A); extensive bowel wall thickening (Type B); focal bowel wall thickening (Type C) or no abnormality detected (Type D). We compared TUS findings against DBE findings with respect to small-bowel stricture, defined as failure of the enteroscope to pass through the small bowel. RESULTS Small-bowel stricture was detected by DBE in 11.3% (90/796) of patients. Strictures resulted from Crohn's disease (n = 36), intestinal tuberculosis (n = 24), malignant lymphoma (n = 9), ischemic enteritis (n = 6), NSAID ulcer (n = 5), radiation enteritis (n = 2), surgical anastomosis (n = 2) and other abnormalities (n = 6). Stricture was detected by TUS in 93.3% (84/90) of patients, and each such stricture fell into one of the three types of TUS abnormality. The remaining 6 strictures were detected only by DBE. DBE-identified strictures corresponded to TUS findings as follows: 100% (43/43) to Type A, 59.1% (29/49) to Type B, 14.8% (12/81) to Type C and 1% (6/623) to Type D. Correspondence between stricture and the Type A classification (vs. Types B, C and D) was significantly high, as was correspondence between stricture and Type B (vs. Types C and D). CONCLUSIONS TUS was shown to be useful for detecting small-bowel stricture. We recommend performing TUS first when a small-bowel stricture is suspected.

Abstract
BACKGROUND Almost 70-80 % of patients with Crohn's disease and virtually all patients with ulcerative colitis have colorectal mucosa involvement. Colon capsule endoscopy is an interesting option for patients unable or unwilling to undergo colonoscopy. We report our experience with the second-generation colon capsule PillCam(®) COLON 2 in the detection of significant lesions in patients with known or suspected Crohn's disease, who refused colonoscopy or underwent incomplete colonoscopic exam. METHODS We have retrospectively reviewed the results of capsule endoscopy in 6 patients who refused colonoscopy (n = 3) or underwent incomplete colonoscopic exam (n = 3) between March 2011 and October 2012. In all patients, a CT scan was obtained before capsule endoscopy to rule out significant stenosis. RESULTS In our series of 6 patients, 4 had both small bowel and colonic involvement. The use of the PillCam(®) COLON 2 capsule allowed a thorough examination and evaluation of the mucosal lesions with high acceptability, the method being perceived as noninvasive by the patients. No adverse events related to the capsule or bowel preparation were recorded. CONCLUSION In this patient population, PillCam(®) COLON 2 capsule endoscopy was safe. The capsule findings had an important impact on treatment decisions and patient management.
