RESUMEN
Despite the current increase in revisional bariatric surgery (RBS), data on the sustainability of weight loss remain unclear. A systematic review and meta-analysis were performed to assess weight loss outcomes in adult patients undergoing RBS with follow-up > 2 years. Twenty-eight observational studies (n = 2213 patients) were included. The %TWL was 27.2 (95%CI = 23.7 to 30.6), and there was a drop in BMI of 10.2 kg/m2 (95%CI = - 11.6 to - 8.7). The %EWL was 54.8 (95%CI = 47.2 to 62.4) but with a high risk of publication bias (Egger's test = 0.003). The overall quality of evidence was very low. Our data reinforce that current evidence on RBS is mainly based on low-quality observational studies, and further higher-quality studies are needed to support evidence-based practice.

There is no agreement whether prophylactic thoracic duct ligation (TDL), with or without resection, during esophagectomy for patients with cancer is beneficial. The effects of these procedures on postoperative complications and overall survival remain unclear. This systematic review included 16 articles. TDL did not influence short- and long-term outcomes. However, thoracic duct resection increased postoperative chylothorax and overall complications, with no improvement in survival.
