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.

Histology of the Small Intestine
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
