PROSPECTIVE META-ANALYSIS OF RELEASED WEIGHT LOSS AND SUCCESS RATE OF ARGON PLASMA COAGULATION TO SUTURE AND SURGERY PROCEDURES POST-BARIATRIC SURGERY: STATUS OF THE ART OF ENDOSCOPIC TREATMENT
Introduction: Currently, 30% of the world's population is overweight or obese. Roux-en-Y gastric bypass (BGYR) and vertical gastrectomy are the most commonly performed techniques in Brazil and worldwide. Objective: Conduct a meta-analysis of the results of using argon plasma coagulation (APC), suture (SUT), and surgery (SUR), to clarify the safety and efficacy of using argon plasma to other procedures. Methods: The quality of the evidence was classified as high, moderate, low, or very low, according to the risk of bias. The Variance (α2) and One-Way (ANOVA) test were applied, adopting the α level less than 0.05 with a statistically significant difference for the 95% CI. The value of R-sq (R2) was analyzed to discover the imprecision or heterogeneity of the analyzes. Results: A total of 34 studies were found, eight to APC, twenty to SUT, and six to SUR. For relapsed weight loss (RWL), the means for APC, SUT, and SUR were respectively 19.39 ± 10.94, 26.06 ± 16.71, and 17.05 ± 9.85, and for SR, the means were respectively 89.75 ± 16.75, 86.80 ± 11.44, and 76.00 ± 21.57. There was a small difference between the values of APC averages with SUT and SUR, both in relation to RWL and SR, with p>0.05, with a high association (R2 ≥ 50%). Conclusion: It was shown that the APC technique showed excellent results in terms of RWL and SR compared to the other techniques, with no statistically significant difference. Thus, the results of the APC strongly point to its potential use.
