Background
Surgical strategies in patients with BMI > 55 kg/m
2
are not well established.
Objectives
The objective of this study is to compare the long term results and complications of 1- vs. 2-stage laparoscopic “Roux-en-Y″ gastric bypass (LRYGB) for patients with BMI > 55 kg/m
2
.
Methods
Retrospective review of the complications and outcomes, between January 2007 and January 2010, for patients with a BMI > 55 kg/m
2
who underwent directly a LRYGB (1-stage) or a LRYGB as a 2nd stage of a laparoscopic sleeve gastrectomy (LSG).
Results
Twenty-four patients were enrolled (no patient was lost during the 5-year follow-up). In the 1-stage LRYGB group, two patients had grade II complications according to Clavien-Dindo classification. In the 2-stage LRYGB group, complications of the first and the second surgery were summed. There were no differences between the two groups despite being heterogenous (more men with a higher BMI in the 2-stage group). There was a statistically significant difference in the final BMI in 1-stage LRYGB group compared to the 2-stage LRYGB group (34.46 ± 6.29 vs. 40.40 ± 3.47;
p
 = 0.01, respectively) and in percentage of excess of BMI loss (%EBMIL; 69.80 ± 19.96 vs. 54.54 ± 13.93;
p
 = 0.04, respectively).
Conclusions
In patients with a BMI > 55 kg/m
2
, both 1- and 2-stage LRYGB give good long-term results. If feasible, a 1-stage LRYGB obtains a better percentage of excess of BMI loss but if not possible, the strategy of initially performing a laparoscopic sleeve gastrectomy followed by a LRYGB is safe and there were no differences in complications.
