Capsule endoscopy findings following negative second look endoscopy in patients with suspected small bowel bleeding at a tertiary care center in Sri Lanka

Capsule endoscopy demonstrated a high diagnostic yield in Sri Lankan patients with suspected small bowel bleeding who had normal initial and second-look endoscopies. The proximal small intestine was the commonest involved segment, and, contrary to previous studies, inflammatory lesions were the predominant finding. We recommend low-volume bowel preparation as the number of polyethylene glycol sachets did not affect the diagnostic yield or quality of mucosal visualization. This study supports integrating capsule endoscopy into routine clinical practice for evaluating gastrointestinal bleeding and recommends performing a second-look endoscopy before proceeding to capsule endoscopy.
