Key result
Laparoscopic sleeve gastrectomy induced comparable excess weight loss to Roux-en-Y gastric bypass (63.5% vs 71.2%, P=0.073), but had a higher surgical revision rate (4.8% vs 0.4%, P=0.011).

Does laparoscopic sleeve gastrectomy compared to laparoscopic Roux-en-Y gastric bypass improve weight loss and surgical outcomes in obese Korean patients?
Absolute Event Rate: 63.5% vs 71.2%
p-value: p=0.073
Laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass provide comparable mid-term weight loss in obese Korean patients, though sleeve gastrectomy is associated with shorter operative time and hospital stay but a higher rate of surgical revision.
No takes yet. Share an insight, caveat, or question.
Comparable mid-term weight loss supports either procedure in Korean patients; leaves open durability questions given higher LSG revision rates in retrospective data.
Ji Yeon Park (2015) conducted a cohort in morbid obesity (n=340). Laparoscopic sleeve gastrectomy vs. Laparoscopic Roux-en-Y gastric bypass was evaluated on mean percentage of excess weight loss (%EWL) (p=0.073). Laparoscopic sleeve gastrectomy induced comparable excess weight loss to Roux-en-Y gastric bypass (63.5% vs 71.2%, P=0.073), but had a higher surgical revision rate (4.8% vs 0.4%, P=0.011).
