Abstract

Background

Capsule endoscopy (CE) retention remains a concern in patients with suspected or known Crohn’s Disease (CD).

Aim

The aim of this study was to evaluate the ability of a patency capsule (PC) to establish functional patency in pediatric patients with suspected or known, symptomatic IBD.

Methods

A prospective, single center study evaluating the impact of CE on CD management used PC to qualify patients for CE. Patients excreting an intact PC, usually within 40 h of ingestion, were able to undergo standard video CE. Excretion time, structural integrity and patient safety were evaluated.

Results

Eighteen patients (10–16 years of age; 9 male; 5 known CD, 3 indeterminate colitis, 1 ulcerative colitis, 9 suspected CD) ingested the PC. Fifteen patients excreted intact PC (mean 34.5 h), 12 patients within 40 h (range 9–60 h). Sixteen (89%) underwent subsequent CE successfully. CD was eventually diagnosed in all patients having PC transit ≥40 h, whereas CD was the diagnosis in 9/12 (75%) in those patients who passed the PC within 40 h. The mean time of passage for an intact PC was 34.7 h, the longest 60 h. There were no capsule retentions or adverse events.

Conclusions

The PC appears to be a useful screening tool for functional patency of the small bowel in suspected or known pediatric CD. Delayed passage of an intact PC requires careful interpretation.
