Diseases of the digestive tract such as Crohn’s disease or celiac disease.
Familial risk: The risk of disease is increased in hereditary nonpolypous colon carcinoma syndrome (HNPCC) and familial adenomatous polyposis (FAP).
Dietary habits may also play a role.
Small bowel cancer causes no complaints for a long time. Nonspecific symptoms such as abdominal pain, nausea, vomiting, diarrhea, or constipation can be caused by small bowel cancer, but are more commonly due to other bowel disease. Blood in the stool should definitely be clarified by the doctor.
In order to make the diagnosis, the following investigations are usually carried out:
X-ray examinations (eg CT, contrast medium X-ray and further imaging studies)
Gastrointestinal Reflection (Gastroscopy): In this examination, the small intestine can be viewed from the inside and tissue samples taken for further examination. The examination of the tissue samples provides information about whether cancer is present or not.
The treatment of small bowel cancer is planned individually. Decisive for the choice of therapy are the size and extent of the tumor. The main treatment methods are:
These therapies are used alone or in combination.
The carcinoid is a so-called neuroendocrine tumor. It is based on hormone-producing cells in the gastrointestinal tract or other organs. Carcinoids are most common in the cecum or small intestine.
Affected suffer from hot flashes, palpitations, abdominal pain and diarrhea.
In order to diagnose the small intestine carcinoid, certain hormones and their degradation products must be detected in the blood.
Carcinoid can be treated in the same way as other small intestinal tumors: surgery, chemo- and / or radiotherapy. In addition, can also be treated with drugs that inhibit hormone production.
