Effectiveness of laparoscopic roux-en-y gastric bypass and sleeve gastrectomy for weight loss to treat obesity in a hospital of brazil's national health system
Abstract
Introduction: Surgery is the most effective therapeutic option for obesity treatment. This effectiveness can be measured by anthropometric parameters. By the Brazilian Society of Bariatric and Metabolic Surgery, the surgical success is based on total weight loss. Another criterion, for the analysis of success and efficacy, is the percentage of excess weight loss (%EWL). The main surgical techniques are Roux-en-Y Gastric Bypass (RYGB) and Sleeve Gastrectomy (SG) and show consistent weight loss results. In Brazil, there are few reports with results of bariatric surgery, mainly in the National Health System (SUS). Objective: To present the efficacy of the weight loss of RYGB and SG performed at Hospital José Martiniano de Alencar (HMJMA), a SUS institution in Ceará, and to relate it with data from the medical literature. Materials and Methods: We reviewed the records of 61 patients undergoing bariatric laparoscopic surgery from November 2018 to March 2020. The follow-up rate (FR), success rate (SR) and %EWL were evaluated and compared with other studies. Results: An average FR of 87%, global SR above 90% and global %EWL of 28, 56, 73, 85 in the 1st, 3rd, 6th, 12th month postoperatively, respectively. Comparing the two techniques, a statistically significant increase in the %EWL of the RYGB was observed in relation to the SG at the 6th and 12th month. There was no difference at the 1st and 3rd month. Conclusions: The HMJMA presents FR higher than other services that treat obesity, SR satisfactory and has %EWL comparable to that described in international literature.
