Introduction: long term weight loss and resolution of comorbidities make laparoscopic Roux -en- Y gastric bypass (LRYGB) an excellent alternative for the treatment for morbid obesity.
However it is still considered a technically challenging operation and it is usually associated with a long learning curve.
Methods: retrospective analysis from prospective collected data base was performed. Patients who underwent LRYGB were included. Demographics, operative time, length of stay (LOS), weight loss, morbidity and mortality were evaluated. Data are expressed as average ± standard deviation.
Results: between 4/2003 and 9/2011, a total of 5000 underwent LRYGB at our institution; 64% were female, age 43±11, initial weight 133±28 kg, initial BMI 48±9 kg/m2. For the first 150 patients operative time was 180±21 min. which was gradually decreasing to 102±14. LOS was
48±56 hrs. Percentage excess weight loss (%EWL) was 49±13, 64±16, 78±19, 79±20, 73±20, 69±22, 65±24, 57±23% at 3, 6, 12, 24, 36 months, 4, 5 y 6 years respectively; 30-day mortality was 0.1% and mortality after that period was 0.26%. Complication rate was 3.5% and 15% for early and late complications respectively.
Conclusion: LRYGB offers an effective alternative for the treatment of morbid obesity. LRYGB has demonstrated to be safe given its low morbi-mortality when performed by an experienced group with high volume of surgeries.
