Small bowel capsule endoscopy is a minimally-invasive
endoscopic investigation that is often used in clinical
practice to investigate overt or occult gastrointestinal (GI)
bleeding among other clinical indications. International
guidance recommends small bowel capsule endoscopy
as a first-line investigation to detect abnormalities in
the small bowel, when gastroscopy and colonoscopy fail
to identify a cause of GI bleeding. It can diagnose with
accuracy abnormalities in the small bowel. However,
there has been increasing evidence indicating that
small bowel capsule endoscopy may also detect lesions
outside the small intestine that are within the reach of
conventional endoscopy and have been probably missed
during prior endoscopic investigations. Such lesions
vary from vascular deformities to malignancy and their
detection often alters patient management, leading to
further endoscopic and/or surgical interventions. The
current study attempts to review all available studies in
the literature and summarise their relevant findings
