Hutcheon DA, et al. - In patients undergoing primary vertical sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB), researchers determined the impact of short-term preoperative excess weight loss (EWL) on postoperative outcomes. Observations indicated an association of preoperative weight loss of ≥8% excess weight [while following a 4-week LCD (low calorie diet)] with a significantly greater rate of postoperative EWL over 1 year, along with shorter operative duration and hospital length of stay.
