Title: Preoperative Weight Loss in Super Obesity: Influence on Perioperative Morbidity and Mortality in Patients undergoing Gastric Bypass
Citation: OBESITY SURGERY, v.22, n.9, p.1353-1354, 2012
Abstract: Introduction Super obesity (SO) is increasing in greater proportions, and now represents 30 % of morbidly obese patients. In SO morbidity and mortality rates are greater. The preoperative weight loss in SO decreases operative time, and apparently diminishes morbidity. Based on these data, we initiated a program of preoperative weight loss for the SO. The treatment is based on hospitalization, low-calorie diet, biometrics control and physical activities, aiming to analyze weight loss and influence of weight loss in the perioperative outcome. Materials & Methods Thirty patients underwent our SO preop weight loss program, from 2006 to 2011. The mean age was 46 years, and mean BMI of 66 kg/m2 and the majority was female. All patients underwent gastric bypass after the weight loss. The average caloric intake was 5 cal/Kg/day. Results The mean weight loss was 1.9 kg/week, and after 14 weeks the mean weight loss was15.2 % of initial weight. The mean hospital stay was 21.3 weeks, and the mean weight loss was 19.7 %. All had satisfactory recovery from surgery. The mortality was null. In the last five years, from the total of 592 surgeries, 193 was performed in SO. The SO and general morbidity was 11.14 % and 20.2 %, respectively, and mortality 0.84 % and 2.07 %. Discussion In SO a preoperative weight loss is an important tool to reduce surgical risks. Hospitalization, with low-calorie diet and multidisciplinary follow-up is a safe and effective way to achieve weight loss preoperatively. Conclusion After a mean of 19,7 % of initial body weight loss, the studied group showed an important decreasing in morbimortality when compared with our previous experience. Preoperative weight loss should be encouraged in SO, and a specific program can significantly diminish surgical risks in this complex group of obeses.
