[Primary small bowel malignancies].

Abstract

Primary small bowel tumors are extremely rare. They are often first manifested as symptomatic in advanced stages. To date, no screening options are available. The diagnostics include sectional imaging, various endoscopic procedures and positron emission tomography (PET). Depending on the histological type and tumor stage, endoscopic treatment options are available in addition to surgical resection. Following histological confirmation, discussion in the interdisciplinary tumor board is recommended for the planning of the treatment procedure. In emergency situations (hemorrhage, small bowel obstruction) laparotomy is usually performed prior to the elaborate diagnostics.
