Small bowel tumors
Small bowel tumors
small bowel cancerSmall bowel tumors are quite rare.

Some tumors can lead to obstruction, like blockage of the small bowel.
Signs of small bowel obstruction are severe abdominal pain, vomiting, gas and defecation stopping, bloating, dehydration. Clinical signs may include worsening general condition (weight loss), abdominal pain, melena (digestive hemorrhage), rectal bleeding, microcytic anemia, and transitory disorders (diarrhea).

Diagnosis includes upper endoscopy or video endoscopy with a capsule.

A scanner of the chest, abdomen and pelvis with an injection of iodine contrast medium (+/- enteroclis) allows you to identify the tumor and evaluate local, regional lesions of the lymph nodes, as well as possible long-term lesions (pulmonary metastases or liver metastases).

The treatment of such tumors is a surgical resection performed by a gastro surgeon.

Afterwards, the analysis of the removed tissue is performed. The main tumor is often an adenocarcinoma located in the duodenum or proximal jejunum; it is this tumor that produces extremely few symptoms.
Other rare forms of malignant neoplasms of the small intestine: lymphomas and carcinoid tumors. Depending on the stage of the tumor and the type of cancer, chemotherapy or another treatment may be offered.
