The obesity is the result of a trouble between the caloric ingestion and the energetic expense. The morbid obesity includes patients with index of corporal bigger mass than 35 with associate co-morbidities or with major indexes of 40 without co-morbidities. These patients do not achieve losses of the supported overweight when they try it across medical treatment, for it the surgical treatment is the unique option that allows the effective long-term loss of weight. The gastrectomía in sleeve allows to resect the portion where it predominates over the production of ghrelina: orexígen hormone involved in the regulation of the appetite, providing an additional effect to the restrictive derivative of the decrease of the gastric volume. 11 patients included in the clinical trial 36 % men and 64 % women. The average IMC was of 42 kg/m2, the morbidities were suffering 54 % of the patients and the most frequent were dislipidemia and hypertension, operative average time was 90 minutes, there was an alone major complication that deserved conversion and the evolution post operative was marvellous with losses of the overweight of 66 % and decrease of the IMC of 25 % in average to six months, with improvement of 100 % of the morbidities. The gastrectomía in sleeve is an effective, simple, reproducible procedure, with scanty morbidity that supports the physiology of the gastric voidance with the addition of the hormonal influence across the decrease of the production of grelina and other hormonal mechanisms that take part in the regulation of the appetite and the satiety.
