ROTELLAR, F. et al. Laparoscopic bariatric surgery: proximal gastric bypass. Anales Sis San Navarra [online]. 2005, vol.28, suppl.3, pp.33-40. ISSN 1137-6627.

The spectacular increase in the prevalence of obesity in our society and the significant complications and comorbidities that it gives rise to have stimulated the interest of scientists and public in this pathology. Surgical treatment is at present the only efficient and lasting treatment for morbid obesity and in many cases it appreciably improves, and even definitively cures, associated complications such as the case of diabetes or hypertension. Amongst the different techniques of bariatric surgery, the gastric bypass (GBP) seems to be definitively establishing itself, since it offers an excellent balance between loss of weight (70% of the excess), surgical risk and subsequent quality of life. The possibility of carrying out this technique employing a laparoscopic approach has improved its acceptance by doctors and patients while it has made it possible to reduce morbidity and mortality, length of hospital stay and costs. Proximal GBP is carried on those patients with an BMI <60 Kg/m²; for BMI 60 Kg/m2 the GBP employed is denominated distal. Between October 2003 and November 2005, our centre performed 55 laparoscopic proximal Roux-en-Y gastric bypasses via laparoscopy. These involved 42 women and 13 males with an average age of 44 years. The average BMI was 43.5 (35-55.8). The average basal weight was 116.15 Kg. There was no peroperative mortality, nor reinterventions. The BMI after 12 months was 28.4. The average basal weight was 74.2 Kg. Laparoscopic Roux-en-Y proximal gastric bypass is a safe and efficient technique for the treatment of morbid obesity.
