Abstract

INTRODUCTION: Obesity is an important health condition that is related to high rates of morbidity and mortality. Bariatric surgery, although effective, has limited indications and may pose a risk of early and late postoperative complications, one of which is related to the gastric retaining ring, such as erosion, sliding of the device, and food intolerance. One of the modalities used in the endoscopic treatment of ring extraction is the use of stents, which represents a minimally invasive, safe, and effective alternative to the detriment of surgical treatment. OBJECTIVE: To characterize the modalities of endoscopic treatment using Stents for the treatment of complications associated with the retaining ring in the postoperative period of bariatric surgery and to determine the success rate of the different methods of endoscopic treatment. METHODS: The present study will follow an international model of systematic review and meta-analysis, following the rules of PRISMA. The search strategies for this systematic review will be based on the keywords (MeSH Terms) “Obesity. Endoscopy. Bariatric surgery. Gastric Bypass. Stents ”, with publications between 2010 and 2020, in order to analyze more recent scientific publications. Meta-analysis: A common descriptive statistical analysis will be carried out, obtaining the values of total N, mean, standard deviation, confidence interval (CI), and percentage (frequency) for all predictors. The One-Way test (ANOVA) will be applied, adopting the α level less than 0.05 with a statistically significant difference for the 95% CI. The value of R-sq (I2) will be analyzed to discover the inaccuracy or heterogeneity of the analyzes. The S factor will indicate the standard deviation between the data points and the adjusted values.
