Small bowel malignanciesSmall bowel malignancies

Prior to SBCE sb tumours = 1 - 2% of all GI malignancies

Now it is thought to compromise 5%

PillCam™ Trial = incidence of small bowel tumors among 1,235 patients – 6% - 9% (Corbin, Bailey, Keuchel)

60% of SBTs are malignant- adenocarcinomas, carcinomas, melanomas,

lymphomas and sarcomas40% of SBTs are benign

GISTs, hemangiomas, hamartomas, and adenomas

Small Bowel malignanciesSmall Bowel malignancies

Often diagnosed late or incidentally at laparotomy Malignant tumors of small bowel (poor prognosis)

Metastases - 45% - 75%Unresectable - 20% - 50%

80% of SBTs undergoing SBCE present with obscure GI bleeding/anemia Improved outcome of earlier diagnosed tumors in the small bowel

On average patients with SBTs who present for SBCEs have already undergone detected SBTs after patients had undergone an average of 4.6 negative endoscopic procedures
