However, the authors encountered significant complications with the use of a polyp retrieval net. Complications included traumatic oesophageal intubation and the cumbersome nature of release of the capsule in the duodenum.

While swallowing is not a major issue in adults, gastric retention of the capsule remains a noticeable complication in ∼5% of individuals.2 Various techniques including body position, motility medications, …
