Gastrointestinal, Colon and Rectal Tumours

Are all tumours malignant or dangerous? The word tumour means “overgrowth” or “lump” and says nothing about benignness or malignancy.

Which symptoms are caused by tumours? Tumours of the stomach and intestine cause late symptoms such as weight loss, bleeding, loss of appetite, up to life-threatening intestinal obstruction, etc. Therefore, it is all the more important to find them as part of a screening colonoscopy or gastroscopy.

How is a tumour detected?  By means of clinical and proctological examination, gastroscopy, colonoscopy and radiological examination methods. As part of the endoscopic examinations, tissue samples of the tumour are taken, which are then examined histologically to further determine the tumour.

Does a tumour need surgery? Yes. We remove benign polyps in the intestine as part of the gentle colonoscopy.

How is a tumour operated on? Depending on the local findings and extent, I operate on gastric tumours, intestinal tumours and rectal tumours laparoscopically with a buttonhole technique as minimally invasive and as gentle as possible. It is often possible to perform the operation with just a single incision. If necessary, I also operate on tumours using conventional methods via the abdomen or the anal canal.

However, before surgical rehabilitation takes place, I create a tailor-made treatment concept for each patient with my colleagues from oncology, radiotherapy and radiology as part of a tumour board. Postoperative care is also provided in close cooperation with oncologists, radiotherapists and radiologists.
