Video Capsule Endoscopy as a Tool to Detect Small Bowel Neuroendocrine Tumors

#857

Introduction: Recent studies suggest that video capsule endoscopy (CE) should be implemented in diagnostic work-up in patients with suspected small bowel tumors. Small bowel is the primary site in 80%-85% of patients with intestinal neuroendocrine tumors (NET). In 10%-15% of patients diagnosed with metastasized NET, the localization of the primary tumors remains obscure.

Aim(s): Evaluate the efficacy of CE in small bowel NET detection in this setting.

Materials and methods: Between January 2010 and October 2013, 10 patients with metastasized NET and unknown primary tumor localization were referred to our institution. CT, MRI and PET/CT were carried out and failed to detect the primary tumor site. All patients underwent CE using a PillCam® SB2 capsule and the videos were read using Rapidv5 software (Given Imaging). Patients with univocal findings were considered for surgery.
