BACKGROUND: The impact of preoperative weight loss on outcomes following laparoscopic Roux-en-Y gastric bypass (LRYGB) is a controversial issue. We evaluated our outcomes of LRYGB in patients who lost different amount of weight prior to surgery.
METHODS: Patients who underwent primary LRYGB were divided in three groups on the basis of preoperative weight loss percentage. Group A comprised 166 patients, who lost <5 % of their weight preoperatively; group B comprised 239 patients who lost >5 to 10 % and group C included 143 patients who lost >10 %. Intra- and postoperative complications at 30 days, hospital stay, and outcomes were evaluated.
RESULTS: Significant difference was found in operative (mean ± SD) time [104.43 ± 36.40 min in group A, 80.08 ± 23.07 min in group B, and 76.99 ± 23.23 min in group C; p < 0.001 in group A versus group B or group C; p = 0.210 in group B versus group C]. Difference in hospital stay was significant (3.33 ± 3.22 days in group A, 2.10 ± 2.77 in group B, and 1.87 ± 1.44 in group C; p < 0.001 in group A versus groups B or C). Overall postoperative morbidity rate was 33.13 % in group A, 19.25 % in group B, and 11.89 % in group C, with significant difference in group A versus groups B or C (p = 0.002 and p < 0.001). Mean excess weight loss was significantly higher (72.7 %) in group C versus group A (63.1 %) (p = 0.015) at 12 months.
CONCLUSIONS: Weight loss >5 % prior to LRYGB may reduce morbidity, and preoperative weight loss >10 % may improve weight loss outcomes at 1-year follow-up.
