INDICATION
When is a Patency Test needed?
According to pooled results on retention rates of small bowel capsule endoscopy from more than 220 studies involving more than 22,000 procedures, pooled retention rates are as follows:
Obscure GI Bleeding
Neoplastic Lesions
Definite or Suspected Crohn’s Disease
Overall (weighted average)
1.2%
2.1%
2.6%
1.4%
RETENTION RATE
Liao et al, Indications and detection, completion, and retention rates of small-bowel capsule endoscopy: a systematic review, Gastrointestinal Endosc. 2010 Feb;71(2):280-6.
The risk of capsule retention in patients with suspected Crohn´s disease without obstructive symptoms and without a history of small bowel resection or known stenosis is low and comparable to that of obscure GI bleeding.1
Non-standard in patients with suspected Crohn's
disease
Standard in patients with established
Crohn's disease
The latest ESGE guideline recommends PillCam™ Patency Capsule as per the following:

PillCam™ Patency Capsule is the best Exam to prove GI Patency prior to a CE Exam3
Fibrostenosing Stricture in SBSmall Bowel Stricture
Radiographic evidenceindicates strictures
Stricture
Small Bowel Stenosis With CE
• The PillCam™ Patency capsule detects stenotic areas in the small bowel and differentiates inflammatory strictures (functional patency) from fibrotic strictures4
• The PatCap might be superior to CT in predicting intestinal stricture, as it detects stenosis undiagnosed by CT. CD patients should be examined with the intestinal patency by PatCap before VCE5
• 100% of patients with a suspected stricture in MRE could be safely evaluated by CE after a correct expulsion of the Agile Patency Capsule6
