Introduction:

Obesity is the second cause of death susceptible to prevention. Surgical treatment is the only effective and proven treatment for severely obese patients (body mass index > 40 kg/m²). Bariatric operations prolong survival and correct diseases associated with severe obesity.

Objectives:

To determine the short-term and long-term results of bariatric surgery in obese patients admitted to the National Hospital of Itauguá from March to December 2019.

Materials and methods:

Observational, descriptive cross-sectional, retrospective study with non-probabilistic sampling at convenience. We included patients of both sexes, over 16 years of age with obesity who underwent bariatric surgery and were admitted to the General Surgery Service of the Hospital Nacional de Itauguá in 2019.

Results:

Twenty-four patients were followed up in the study, with an average weight of 117.5 kg and a mean BMI of 43.5. 67% presented with grade III obesity and 70% with ASA III. The most frequently used surgical technique was vertical gastrectomy in the laparoscopic sleeve. The average postoperative weight loss at 12 months was 56.4 kg. The average postoperative hospital stay was 48 hours. There were no complications in 96% of cases.

Conclusion:

The result of our study suggests that bariatric surgery has proven to be an alternative with excellent results for the treatment of morbid obesity, , thus improving not only chronic clinical pathologies but also the quality of life of the patient with increased life expectancy.
