Clinical Outcomes of Single Stage Versus Two-stage Treatment of Severe Obesity

Clinical Outcomes of Single Stage Versus Two-stage Laparoscopic Roux-en-y Gastric Bypass in the Management of Super Obesity: a Propensity Score Weighted Analysis'

Laparoscopic Roux-en-Y gastric bypass (LRYGB) in super obese patients (BMI≥50kg/m2) is a challenging operation. Weight reduction with intragastric balloon (IGB) prior to LRYGB may improve operative outcomes and improves weight loss. We assessed 155 patients, with a BMI≥50 kg/m2 who underwent either intra-gastric balloon (IGB) insertion followed by LRYGB (two-stage group), or LRYGB as the definitive bariatric procedure (single-stage group) in our institution. Two stage procedure was adopted for high-risk individuals.

Inclusion Criteria:

• patients, with a BMI≥50 kg/m2, underwent either intra-gastric balloon (IGB) insertion followed by LRYGB (two-stage group), or LRYGB as the definitive bariatric procedure (single-stage group)
