1st Visit:
To value if you meet the criteria to be candidate for this Surgery by reviewing the Medical History. Presenting information about our operation and the rest of existing operations.
It is necessary a preoperational study (complete analytical, respiratory functional tests, cardiac examination with effort tests, radiological study –abdominal scan, radiological contrast study of oesophagus stomach and duodenum-, and a psychological and quality of life assessment).

2nd Visit:
Preoperational situation is assessed by the surgeon and anaesthetist (they pay special attention to the intratracheal intubation conditions and the necessity of special preoperational preparation). The patient is given instructions about how he or she must prepare the day before the operation.


Operation day: Preoperational medication at home. Preparation for the operating room (shaving, bandaging the legs, looking for a venous via and premedication in order to avoid the impact caused by the transfer and entry into the operating room –the patient goes anaesthetized from the room to the operating room). Operation time (about ninety minutes). The patient wakes up in the operating room. He/She is transferred to his/her room again. When the patient wakes up, we encourage him/her to get up and go to the toilet by him/herself.

The day after the operation: It is done a radiological study of the only anastomosis (connection between the stomach and intestine) in order to check that everything properly works before beginning to eat again. If everything works (that is what happens in almost 100% of the patients), the oral tolerance is begun by drinking water, camomile tea and fruit juice. Once the oral tolerance has been tested, the patient goes home 24 hours after the operation, without stitches or drainage. The patient is given the written instructions for the first week (he/she only can take liquids) and the mobile phone number of Dr. Carbajo if he/she needs make any question.

3rd Visit:
It is reviewed the diet and general condition of the patient. He/She is given instructions for the 2nd week (only to take liquids, but this time more thick). For the 3 rd and 2nd week he/she can eat anything but beaten. Also we put in writing the medication he/she must take.

4th Visit:
In a month it is reviewed the diet, medication and weight loss. From now on the patient returns to a normal diet (he/she can eat anything). The psychologist values his/ her Quality of Life. It is written a clinical report about the intervention and treatment.

5th Visit:
In 6 months it is reviewed the medication, analytical and weight loss.

6th Visit:
In 12 months it is reviewed the weight loss, analytical and general condition.

Periodic Visits:
They are annually advisable.

THE AVERAGE WEIGHT LOSS (From 3 moths on it depends on the excess of initial weight)

The excess of weight is the difference between what the patient should weight according to his/her height and what he/she actually weighted at the moment of the operation: 1 month: 20 kg (between 15 and 25) 3 months: 30 kg (between 25 and 35) 6 months: 40 kg (between 30 and 50) 12 months: 50 kg (between 40 and 60) 18 months: 60 kg (between 40 and 70) 24 months: 80 kg (between 40 and 100)
