Retrograde NaviAid Enteroscopy-Assisted Resection of Distal Small Bowel Hamartomatous Polyps.

Hamartomatous polyps are gastrointestinal tumors that may present with small bowel obstruction requiring surgical resection, while others may present earlier as symptomatic anemia prior to becoming an obstructing mass. Video capsule endoscopy has enhanced the early detection of small bowel lesions. However, endoscopic interventions especially for distal small bowel lesions are limited due to long procedure times, technical challenges in achieving depth of insertion, and the requirement of specialized deep enteroscopy equipment with advanced endoscopy training, which are not always available. Therefore, surgical intervention is often required. NaviAid-assisted enteroscopy, a novel thorough-the-scope balloon, results in deep anterograde and retrograde intubation of the small intestine using standard colonoscope and can be used for rapid therapeutic intervention. We present two cases of distal small bowel hamartomas which were resected via retrograde NaviAid-assisted enteroscopy, thus, preventing surgery.
