Purpose: To demonstrate through a controlled study whether the use of tranexamic acid in bariatric surgeries is effective for bleeding control. Methods: Prospective, comparative, and double-blind study performed with patients from 18 to 65 years old submitted to bariatric surgery. The selected patients received venous tranexamic acid (TXA) during the induction of anesthesia or not (CG). The anesthesia and thromboprophylaxis protocols were similar among the groups. For statistical analysis, the χ2 and analysis of variance tests were performed at a significance level of p < 0.05, using the statistical program SPSS 21.0®. Results: Sixty-one patients were included in the study, 31 in the control group and 30 in the TXA group (GTXA). In the intraoperative period, the bleeding volume was greater in the CG than in the GTXA. In the postoperative period, the tranexamic acid group had a higher value hematocrit, absence of surgical reoperations due to bleeding complications, and shorter hospitalization time than the control group. Conclusions: The use of tranexamic acid was effective in reducing bleeding rates and of hospital stay length, in addition to demonstrating the clinical safety of its use, for not having been associated with any thromboembolic events.

Purpose To analyze the effectiveness of vertical gastrectomy in the treatment of obese patients, adherence to clinical follow-up and the influence of factors such as gender and age. Methods This is a retrospective, observational and descriptive study, conducted with patients undergoing vertical gastrectomy, operated at Hospital São Domingos, between January 2016 and July 2018. Results Most patients undergoing vertical gastrectomy were female (n = 193, 72.28%) and had a mean age of37.11 ± 8.96 years old. The loss of follow-up was 56.18%. Among adherent patients (n = 117; 43.82%), most patients were female (n = 89; 76.07%) and had a mean age of 37.92 ± 9.85 years old. The mean body mass index (BMI) of the adherents in the preoperative was 37.85 ± 3.72 kg/m2. Both BMI and excess weight (EW) showed a statistically significant difference between pre- and postoperative period. Percentage of excess weight loss (% EWL) was satisfactory for 96.6% of adherent patients. Older patients had a statistically significant lower % EWL compared to the other groups. Conclusions Vertical gastrectomy was effective in the treatment of obese patients, with significant weight loss.(AU)

Purpose: To compare the satisfaction levels about the surgery and anesthesia management, and to analyze the postoperative outcomes of patients undergoing Gastric Bypass and Sleeve Gastroplasty surgeries in a private hospital in Sao Luís-MA. Methods: The sample consisted of patients undergoing Bypass and Sleeve bariatric surgeries from August 2018 to August 2019, who were in the range of 18 and 70 years old and had not used drugs or presented cardiac arrhythmias, dilated cardiomyopathy, and conduction disorder heart. Data were collected from the evaluation forms and recorded in a form with closed questions. Results: Most patients were female (Bypass 56% and Sleeve 67.4%) and aged between 30 and 39 years old (Bypass 32% and Sleeve 55.8%). Information (Bypass 92% and Sleeve 86.1%) was the highest satisfaction index found. Sleepiness in the immediate postoperative period (Bypass 92% and Sleeve 93%) was the main side effect. There were no postoperative complications in patients between the two types of surgery. Conclusions: Patients submitted to Bypass and Sleeve were completely satisfied with the perioperative management. There was no statistically significant difference when comparing adverse effects between the techniques.(AU)
