Roux-en-Y gastric bypass is the second most widely performed surgical modality in the world for the treatment of obesity. In this technique, classic laparoscopic surgical retractors are usually rigid, require an additional incision for its installation, or handled by an assistant during the surgical procedure, and involve the risk of liver injury. The objective of this study was to evaluate and validate a technique of exposure of the esophagogastric junction obtained by the flexible liver retractor in bariatric surgery, comparing its efficacy with the retractor classically used for this purpose. It was a prospective, open, controlled and comparative study in patients with indication of surgery, randomly distributed in two groups: classic (control) and flexible (test) retractor. A total of 100 patients (n=50 control group, n=50 test group) were included, with no statistically significant difference in age and morbidity distribution, with only gender differences (control group obtained a higher proportion of males, (p=0.020). Regarding the mean duration of surgery, no statistically significant difference was observed. Regarding the visibility, it was verified that 100% of the patients in the flexible retractor group had an optimal visibility level, although without statistical significance in relation to the classic group (94%). Invariably, it was necessary to carry a trocar when using the classical retractor, representing an additional wound in the abdominal wall, which could increase the risk of bleeding, infection, herniation or even the inflammatory response to trauma, as well as increasing the number of scars on the skin, an obvious aesthetic disadvantage. The flexible liver retractor has shown to be safe, effective, ergonomic, low cost, with a satisfactory aesthetic profile, requiring no specific instruments to be used, neither new adaptation curve and trainning for its handling
