Oncological surgery

Doctor Dejeu’s team specialises in oncological surgery for diagnosis and treatment or to relieve symptoms.

Oncological conditions require treatment according to current international protocols without compromise. Through close collaboration with the oncology team and decisions are always made in consultation between the teams involved.

The timing of surgery is important to choose well. Commonly treated oncological pathologies are: breast, stomach, colon and rectum, cervix, ovary, thyroid and abdominal metastasis surgery.

We take a multidisciplinary approach to all oncology cases and are there for every patient, regardless of the stage of the treatment process.

Doctor Dejeu’s team has all the procedures for the evaluation and investigation of oncological conditions, including imaging investigations, laboratory tests and tests for the presence of tumour markers, endoscopic examination, as well as surgical diagnostic procedures.

Types of interventions

The latest obesity surgery tailored to each patient.

Gastric sleeve

It is a stomach shrinkage operation that involves removing a large portion of the stomach (about 80%), leaving a much shrunken gastric tube in the digestive tract. The procedure is very effective, both because of the shrinkage and because it removes the portion of the stomach responsible for the formation of a hormone that stimulates the hunger centers. It is performed laparoscopically or classically. Postoperative recovery is rapid, with a hospital stay of 48-72 hours.

Depending on the starting weight, the patient may return to the ideal weight in 1-2 years after surgery. For overweight patients (BMI over 50-60) this type of surgery can be a first step, later completed with a malabsorptive mechanism (gastric bypass). The intervention is followed by an appropriate postoperative regimen and lifestyle improvement. With weight loss, diabetes, hypertension, sleep apnoea can regress to full recovery.

Gastric ring

It involves fitting a silicone ring around the upper portion of the stomach. It basically creates a smaller stomach above the ring. The patient will consume smaller amounts of food and will feel satiated sooner. The ring is connected to a small plastic reservoir (port) placed under the skin. Through this port the diameter of the ring is adjusted by injecting saline. The procedure is performed laparoscopically or classically, with a rapid postoperative recovery. Duration of hospitalization 48-72 hours. The results are comparable to those of the gastric sleeve, although slightly inferior. The procedure is reversible. Postoperatively the patient follows an appropriate diet, as recommended at discharge. The ring can remain and maintain its restrictive effect for many years.

Gastric follicle

It is a type of surgery where the stomach is plumped from the outside in. The resulting stomach will have a much reduced volume. The procedure is performed laparoscopically or classically. Hospitalisation for 48-72 hours followed by an appropriate diet. The disadvantage compared to the gastric sleeve is the persistence of the hormonal mechanism, as no part of the stomach is removed. Similar to gastric ring and slightly inferior to sleeve. It is therefore recommended in patients suffering from a more moderate form of obesity. The decision is made after a pre-operative consultation in which the advantages of each method are discussed in detail, tailored to the needs of each patient.

Gastric bypass

Type of intervention recommended for diabetic patients. After this surgery, all patients experience improvement in their diabetes and up to 80% of patients experience diabetes remission. It is also aimed at patients suffering from less severe obesity, grade 1 and 2, due to its excellent effects on type 2 diabetes. It combines the restrictive mechanism (shrinking of the stomach) with the malabsorptive one (short-circuiting of a large part of the small intestine, so that food will meet the digestive juices, which facilitate absorption, only in the last portion of the intestine). The procedure is performed laparoscopically, minimally invasively, followed by very careful postoperative care (adapted diet and regular check-ups). The patient can reach the ideal weight within the first two years after the intervention, once the comorbidities (diabetes, hypertension, etc.) regress.


Patients asked:

Here’s what patients say about how we’ve improved their health and given them a normal lifestyle again

Depending on the type of tumour, surgery may be needed. This decision is made as a team, by the surgical oncologist and a medical oncologist or radiotherapist.

There are advanced treatments that, along with cancer surgery, can help you heal. Medicine has advanced so much in recent years that a cure for cancer is often possible.

The surgeon and oncology team decide, depending on the location and stage of the cancer, whether you need any treatment before or after surgery.

Definitely. Monitoring and treatments such as radiotherapy, chemotherapy or hormone therapy are indicated by medical oncologists and radiotherapists.

You may experience some side effects, but there are treatments that can help you experience as few side effects as possible.
