Resumen

RICO HERNANDEZ, M.ª A. et al. Five-year comparison of two techniques of bariatric surgery in patients with morbid obesity followed up in a nurse consultation. Nutr. Hosp. [online]. 2009, vol.24, n.6, pp.667-675. ISSN 0212-1611.

Aims: To compare the evolution of weight loss and complications in the patients subjected to two techniques of bariatric surgery (RVG: ring vertical gastroplasty and BP: gastric by pass type Capella) carried out in HospitalLa Paz during the years 2000 and 2001. Material and methods: 51 patients (27 RVG and 24 BP) were operated, and 44 (22 RVG and 22 BP) completed the follow-up at 1 year, 43 (22 RVG and 21 BP) at 2 years, and 28 (10 RVG and 18 BP) at 5 years. The parameters analyzed at 6, 12, 18, 24 months and 5 years were BMI (body mass index), EI (effectiveness index), % LW (percentage of lost weight), % LEW (percentage of lost excess of weight), alimentary intolerances, digestive complications, surgical complications, physical activity and modification of alimentary habits. Results: An important reduction of weight was observed at 6 months with both techniques (% LEW: 45.8% with RVG and 53.4% with BP). After 12 months the loss of weight was significantly higher with BP (% LEW at 2 years: 59.5% with RVG and 83% with BP). However, at 5 years a weight recovery was detected in both groups of patients. At 12 months the patients subjected to RVG tolerated worse the meat and at 18 months the group of BP tolerated worse the rice. There were not significant differences in other parameters. Conclusion: The long term results are better with BP than with RVG. There is a reduction of effectiveness at 5 years that could be related with the modification of alimentary habits and with giving up attendance to the nurse consultation.
