Introduction

Morbid obesity is a very prevalent disease, bariatric surgery being a fundamental pillar in its treatment.

Objective

To analyze the results of weight loss at 1 year in patients operated on gastric bypass and sleeve at the Regional University Hospital (HRU) of Malaga.

Methods

Retrospective observational study, with a follow-up period of 1 year, of 215 patients with morbid obesity who underwent bariatric surgery at the HRU of Malaga with systematic data collection and complete follow-up. 90 subjects had undergone gastric bypass surgery (between May 2003 and November 2018) and 125 by gastric sleeve (between January 2009 and July 2019).

Results

Of the total number of patients, the mean age at the date of the intervention was 44 years, 30.5% were men. The mean BMI before surgery was 50.15 kg/m² and the mean weight 136 kg. One year after surgery, the mean weight loss achieved in the case of gastric bypass was 46.94 kg (range 4.60–111.60 kg) with a mean percentage of excess weight loss of 72.59% (range 14–137%); while with the sleeve technique, there was a mean weight loss of 48.21 kg (range 20–109 kg) with a mean percentage of excess weight loss of 70.09% (range 29–113%). Regarding the global results, the percentage of patients with excess weight loss above 50% was 87.9%, while 70% achieved the double objective of excess weight loss above 50% + BMI below 35 kg/m².

Conclusions

Satisfactory weight results are observed in the short term, with no significant differences between the 2 techniques used in terms of the mean weight loss and the percentage of excess weight loss.
