Abstract

Introduction Colon capsule endoscopy (CCE) has been demonstrated to be a feasible alternative to colonoscopy for the detection of polyps and neoplasia1and avoids intubation and sedation. This study evaluates the utility of CCE in routine clinical practice and its impact on patient outcomes.

Method Retrospective, single-centre, including symptomatic patients attending for CCE using PillCam Colon 2 (Given Imaging, Israel). All patients with known inflammatory bowel disease (IBD) successfully passed a PillCam Patency device prior. Patient demographics, procedural data, final diagnosis and management outcomes were collected.

Results 101 patients were included, mean age 43 years (range 16–95), 73 female, median follow-up 29 months (range 1–52). 48% refused colonoscopy, 29% had an incomplete colonoscopy, 17% chose CCE over colonoscopy and 6% were unfit for colonoscopy. Indication for the procedure: anaemia (24%), IBD assessment (16%) and suspected IBD (60%). The latter had predominant symptoms of diarrhoea (77%), abdominal pain (18%) or weight loss (5%). Procedure completion rate 69%, bowel preparation was adequate in 75%. There were no complications.

Results are summarised in Table 1.

Abstract PWE-029 Table 1

In the anaemia group, CCE altered management in 15%: 3 further procedures (1 double balloon enteroscopy (DBE) and argon plasma coagulation, 1 catheter embolisation and 1 small bowel capsule endoscopy) and 1 altered medication. The remaining 20 were managed conservatively.

In the known IBD group, CCE altered further management in 69% (7 altered medication, 2 surgery, 2 further procedures (1 DBE, 1 colonoscopy), the remaining 5 patients were managed conservatively.

In those suspected as having IBD, this was identified in 7%. Other clinically significant diagnoses were made in 36%. The remaining 57% patients were thought to have functional bowel disorders and were discharged. 3 patients were excluded due to a non-diagnostic examination.

Conclusion CCE may be a useful alternative for detecting clinically relevant pathology in symptomatic patients and can help guide management. An incomplete examination (i.e. distal colon not visualised) was less relevant in the 29 patients who had already had an incomplete colonoscopy beforehand or the 24 patients whose incomplete CCE was sufficient to provide a diagnosis. Although marketed as a colonic imaging device, a third of pathology identified by CCE was in the SB, serving as a reminder that it may be difficult to distinguish symptoms arising from the small or large bowel, or both.

Disclosure of interest None Declared.
