Efectividad de la gastrectomía vertical frente al bypass gástrico en y de Roux en el tratamiento de la obesidad mórbida: ¿cúal es la mejor técnica?

Abstract

The objective of the study was to compare the results after laparoscopic sleeve gastrectomy (LSG) versus laparoscopic Roux-en-Y gastric bypass (LRYGB) in the treatment of morbid obesity in terms of weight loss, comorbidities remission and complications.An observational unicentric study of 154 obese patients who underwent bariatric surgery from 2012 to 2021 was designed. We report the results of 125 LSG patients and 29 patients with LRYGB.The effectiveness of LSG and LRYGB as primary treatment for morbid obesity was comparable, without statistical significance related to weight loss.Regarding comorbidities resolution, LRYGB showed better results. Although both techniques associated low morbidity rate, the LRYGB presented with higher intraoperative and postoperative complications rate and longer hospital stay. On the other hand, LSG required a higher percentage of reinterventions and showed worse results related to preoperative reflux disease remission and de novo reflux onset.
