The first Consultation

In the first diagnostic appointment, your digestive surgeon will give you specific information about the operation of gastric sleeve, explain the possible procedures, perform the medical history and measure certain parameters about your general health, your age, background.

We will request other complementary preoperative tests (cardiac, respiratory, gastrointestinal and psychological analysis), with the aim of guaranteeing the lowest possible risk during the surgical act. We will explain the special care before the surgery.

And we will proceed to the reading and signing of the Informed Consent.

A personalized communication with your bariatric surgeon will help you to decide the technique that best suits your needs and expectations. Do not hesitate to ask about any question that you have doubts or that you are curious about. You must tell your digestive surgeon what your expectations are, so that the latter can assess them and determine if they can be fulfilled completely or with any limitations. The surgeon will explain in detail the results that can be obtained, the surgical technique most appropriate to your case and the type of anesthesia that will be used. We will also inform you about the situation of the hospital center where the gastric sleeve surgery will be performed, the cost of the intervention, the payment method and the financing possibilities.

Surgery for patients who have already undergone surgery for obesity, but have not achieved the necessary result. The failure rate is small, when the patient is well studied, the type of operation is well chosen and the patient follows the recommendations indicated.

¿In what types of patients is revision surgery performed?

For patients who have already been operated on for obesity, but have not achieved the necessary result.

All obesity operations have a failure rate.

The failure rate is small, when the patient has been well studied, the type of operation is well chosen and the patient follows the recommendations indicated.

Why surgery with us for Revision Surgery:

We have an accumulated experience of more than 1,300 patients operated on for Laparoscopic Obesity Surgery in the last 15 years, without any case of mortality and excellent results.

1- A complex operation and for experts:

All the Scientific Societies agree that the revision of an obesity operation should only be carried out by well-trained and specialized surgeons and teams.

2- A safe and effective technique in our hands:

The multidisciplinary preparatory study is fundamental. The cause of the failure of the previous operation must be found.

The initial operation of the patient should be studied and evaluated for possible recovery (more frequent in the gastric bypass), change to another technique (more frequent in the tube or gastric sleeve) or withdrawal and change of technique (gastric band removal).
The experience and strength of the team is essential for making the most appropriate decision and to technically approach a more complex technique and with more surgical risk.

It endorses us:
• Our experience in revision surgery.
• Preparatory preparation meticulous.
• Laparoscopic technique and mini-invasive anesthesia.
• Fast Track postoperative protocol, with admission of only 24 – 48 hours.
• Rapid recovery, normal life in 7 days.
