Abstract

A total of 18,455 patients were included in the comparison of laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy for morbid obesity.

  • Patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) experienced a higher percentage of excess weight loss than those receiving laparoscopic sleeve gastrectomy (LSG).
  • LRYGB was associated with better resolution of hypertension compared to LSG.
  • Improvements in dyslipidemia, gastroesophageal reflux disease, and arthritis were also more pronounced in patients treated with LRYGB.
  • Both LRYGB and LSG had similar effects on type 2 diabetes mellitus.
  • Sleep apnea outcomes were comparable between the two procedures.
