A rare cecal subepithelial tumor in a Crohn´s Disease patient.

Appendiceal tumors comprise a variety of histologic types, including appendiceal mucinous neoplasms, which can be grouped as premalignant lesions, tumors of uncertain malignant potential, and malignant lesions. The appendiceal mucinous neoplasms are characterized by mucinous epithelial proliferation with extracellular mucin and pushing tumor margins, commonly an incidental finding during operative exploration. We report the case of a low-grade appendiceal mucinous neoplasm presenting as a subepithelial lesion in Crohn´s Disease patient.

Out-of-hours endoscopy for non-variceal upper gastrointestinal bleeding.

Background: Most countries lack a well-coordinated approach to out-of-hours endoscopy. Economic constraints and lack of resources have been identified as important barriers.

Objective: To assess the performance evaluation of an out-of-hours emergency endoscopy model of care.
