RESUMO

PURPOSE: Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) remains the most effective procedure to treat severe obesity with proven short- and intermediate-term benefits. The main goal is to describe the effects on weight and biochemical laboratory tests after long-term follow-up (11 years). MATERIALS AND METHODS: A prospective cohort of adults with obesity treated with LRYGB between 2004 and 2010 in one center were studied. Patients with prior bariatric or upper digestive tract surgery, hiatal hernia >4 cm, alcoholism, or decompensated conditions were excluded. The study enrolled 123 patients, with a mean follow-up of 133±29 months and a 14% loss of participants. RESULTS: The percentage of Total Weight Loss (%TWL) at one, five, and eleven years was 30.3±8.4%, 29.1±6.9%, and 23.4±7%, respectively. Of the patients, 61.3% (65/106) maintained a %TWL≥20 after eleven years. Recurrent Weight Gain (RWG) at five and eleven years was 2.6±11.4% and 11 ±11.5%, respectively. At the end of the follow-up, 31.1% (33/106) of patients had RWG≥15%. Hypercholesterolemia and hypertriglyceridemia improved in 85.7% (54/63) and 90.2% (7/61) of the cohort, respectively. Remission of diabetes occurred in 80% of this subgroup. Gallstones developed in 28% of patients, and bowel obstruction due to internal hernia occurred in 9.4%. Anemia due to iron deficiency appeared in 25 patients. CONCLUSION: After surgery, there is a significant and durable loss of weight, with a tendency for late Recurrent Weight Gain. Furthermore, the improvement in biochemical parameters is sustained over time, but surgery's adverse effects may appear later.
