Aims:

Videocapsule endoscopy (VCE) is a non-invasive method for examining the small bowel. VCE retention is the most significant complication of these devices and a patency capsule (PC) may be used to safely perform VCE, in patients with an increased risk of VCE retention.

To describe their experience with PC exams and to evaluate the indications, results and safety profile of its use in the clinical practice.

Methods:

Retrospective single-center including all PiiiCam CP exams performed between 2010 and 2017. PC detection with radiofrequency identification scanner and symptoms evaluation were assessed 30 hours after ingestion. The intestinal tract was considered to be patent if the capsule was not detected by the scanner 30h after ingestion, or if the capsule was later excreted intact. Patients with a positive scanner detection of PC did not performed VCE.

Results:

716 PC were performed (57% women; mean age of 42 ± 15 years). Main indications included Crohn's disease (CD) (44%), suspected CD (41%), suspected small-bowel neoplasia (9%), previous abdominal surgery (4%), NSAID enteropathy/radiation enteritis (0.5%). 11% of patients had a previous diagnosis of small-bowel strictures in abdominal imaging or endoscopic exams and 33% had a history of previous abdominal surgery. The retention rate 30h after CP ingestion was 28%, however 32 (5%) patients excreted an intact CP later. Two (0.2%) patients with CD required hospital admission due to small-bowel obstruction, which was successfully managed with intravenous corticosteroids. The history of small-bowel strictures was associated with non-patency of the small-bowel (p < 0.001). All 551 (77%) patients with small-bowel patency subsequently performed VCE without incidents.

Conclusions:

PC has proven to be a safe and effective exam. As expected, the history of prior intestinal strictures was associated with non-patency of the small-bowel. The rate of PC retention (23%) was similar to that described in other series.
