Aims:

Videocapsule endoscopy (VCE) is a non-invasive method for examining the small bowel. VCE retention is the most feared complication of these devices and a patency capsule (PC) may be used to safely perform VCE.

Our aim was to assess the safety of PC in patients with Crohn's disease (CD) or suspected CD, in routine clinical practice.

Methods:

Retrospective single-centre study including patients with CD or suspected CD with clinical indication for VCE, between 2011 – 2017. PC detection was performed 30 hours after ingestion with radiofrequency identification scanner. Symptomatic PC retention was defined as the presence of typical obstructive abdominal symptoms (postprandial abdominal pain, bloating, nausea, or vomiting).

Results:

608 PC were performed (52% of cases had a definitive diagnosis of CD and 48% of cases had a clinical/imagiological suspicion of CD. The PC retention rate at the 30 hours' evaluation was 27% (29% in CD cases vs. 25% in suspected CD, p = 0.298). Additionally, 31 (5%) patients excreted the PC intact 30 – 72 hours later. Overall, in 475 (78%) patients the small bowel patency was established (75% of CD vs. 81% of suspected CD, p = 0.064) and performed VCE, without incidents. Considering the safety issues, 12 (2%) patients presented a symptomatic PC retention (9 (3%) with CD and 3 (1%} with suspected CD, p = 0.249). Two (0.3%} patients with CD were admitted for small-bowel obstruction following PC, which was successfully managed with corticosteroids. Furthermore, 9 patients, in whom the PC was not detected at the 30 hours' evaluation, presented mild abdominal pain (4 with CD and 5 with suspected CD, p = 0.722).

Conclusions:

The PC test has proven to be a safe modality for securing small bowel patency prior to VCE, with reduced frequency of symptomatic retention, which occurred mostly in patients with a previous diagnosis of CD.
