“…It should be noted that the detection of intestinal strictures and the evaluation of intestinal patency are two different concepts. Although the PC cannot discriminate between fibrostenostic and inflammatory strictures, it offers a superior assessment of functional intestinal patency compared with dedicated SB cross-sectional imaging [77 ▪ ,78]. PC should be used selectively, providing a safe and reliable method for assessing the SB functional patency of patients at increased risk of CR [25].…”

Purpose of review Capsule endoscopy is widely recognized as a safe and effective procedure to evaluate the small bowel and/or the colon noninvasively. Although infrequent, capsule retention is the most feared adverse event related to this technique. A better knowledge of risk factors, improvement of patients’ selection and precapsule patency assessment may further contribute to reducing the incidence of capsule retention, even in patients at increased risk for this complication. Recent findings This review addresses the main risk factors for capsule retention, strategies for risk reduction such as patients’ selection, dedicated cross-sectional imaging and rational use of the patency capsule, as well as management options and outcomes in the case of capsule retention. Summary Capsule retention is infrequent, and it is usually manageable conservatively with favorable clinical outcomes. Patency capsules and dedicated small-bowel cross-sectional techniques such as CT or MR enterography should be used selectively and are both effective in decreasing the rate of capsule retention. However, none of them can completely eliminate the risk of retention.
