Sa1743 Efficacy of Patency Capsule and Abdominal Xray in Predicting Passage of Video Capsule Endoscopy to the Cecum in Patients Suspected of Potential Capsule Retention

Background.In patients with known or suspected risk factors for gastrointestinal stenosis, the PillCam patency capsule (PC) is given before a video capsule endoscopy (VCE) in order to minimize the risk of capsule retention (CR). CR is considered unlikely upon excretion of the PC within 30 hours, excretion in an undamaged state after 30 hours, or radiological projection to the colon.Methods.We performed a retrospective analysis of 38 patients with risk factors for CR, who received a PC from 02/2013 to 04/2015 at Klinikum Augsburg.Results.Sixteen of our 38 patients observed a natural excretion after a mean time of 34 hours past ingestion. However, only 8 patients observed excretion within 30 hours, as recommended by the company. In 20 patients passage of the PC into the colon was shown via RFID-scan or radiological imaging (after 33 and 45 hours, resp.). Only 2 patients showed a pathologic PC result. In consequence, 32 patients received the VCE; no CR was observed.Conclusion.Our data indicates that a VCE could safely be performed even if the PC excretion time is longer than 30 hours and the excreted PC was not screened for damage.

The Impact

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

Capsule Retention

Abstract In 2012, Japan approved the use of a tag-less patency capsule (PC), which evaluates gastrointestinal patency before small-bowel capsule endoscopy (SBCE). This study aimed to evaluate the validity of our modification on the passage criteria for this PC in clinical practice. We retrospectively enrolled 326 consecutive patients who underwent PC examination before SBCE. If X-ray could not reveal the PC in the body during the judgement time (30–33 h after ingestion), we defined it as ‘estimated patency’ and performed SBCE. We employed plain computed tomography (CT) for the second judgement, as needed. The overall patency rate was 95.1%. By X-ray, 41 (12.6%) patients were judged to have ‘estimated patency’, and SBCE could be safely performed. Plain CT judgement was necessary in 32.5%. One PC case had a residual coating film associated with stenosis in a patient with Crohn’s disease (CD), and one (0.3%) SBCE case had capsule retention resulting from false CT judgement. Multivariate analysis revealed that established CD and inpatient were factors related to patency loss. In conclusion, PC is useful for examining gastrointestinal patency, keeping in mind CT misjudgement. If PC was not found in the body via X-ray, performing SBCE as ‘estimated patency’ seemed appropriate.
