Gastrointestinal Endoscopy Guidelines

Introduction to Capsule Endoscopy

The overall incidence of capsule retention is approximately 1.4-2% of all capsule endoscopy procedures, with risk varying by patient population, including 0-1.6% in patients with suspected IBD and 5.2-13% in patients with established IBD 1
High-risk patients, including those with known or suspected intestinal strictures, history of obstructive symptoms, known Crohn's disease, history of small bowel resection, history of abdominal/pelvic radiation, and chronic NSAID use, should undergo pre-procedure evaluation, as recommended by the European Crohn's and Colitis Organisation and the British Society of Gastroenterology 1, 2, 3, 4

Cross-sectional imaging (MRI enterography or CT enterography) before capsule endoscopy is recommended for high-risk patients to identify potential strictures, as suggested by the American Gastroenterological Association and the European Crohn's and Colitis Organisation 1, 2, 4
Use of a patency capsule before video capsule endoscopy is also recommended for high-risk patients, with the understanding that patency capsules themselves carry a small risk of impaction requiring surgical removal, as noted by the American Gastroenterological Association and the European Crohn's and Colitis Organisation 1, 2, 3, 4

In patients with poor GI motility or chronic narcotic use, it is recommended to confirm that the capsule has reached the small bowel within 1 hour of ingestion, as recommended by the American Gastroenterological Association 1
Patients with known intestinal strictures, obstructive symptoms, history of small bowel resection, and chronic NSAID use have a significantly higher risk of capsule retention, as reported by the European Crohn's and Colitis Organisation and the British Society of Gastroenterology 1, 2, 3, 4

For patients with mild symptoms, device-assisted enteroscopy (e.g., double-balloon enteroscopy) for capsule retrieval is considered, with a high success rate and significant reduction in risk of surgery, as recommended by the European Crohn's and Colitis Organisation 2
Successful endoscopic retrieval significantly reduces the risk of surgery, with a hazard ratio of 0.20, as reported by the American Gastroenterological Association and the European Crohn's and Colitis Organisation 1, 2
The informed consent process should include specific discussion about the potential for capsule retention in high-risk patients, as recommended by the American Gastroenterological Association 1
