In the Roux-en-Y gastric bypass technique, classic laparoscopic surgical retractors are usually rigid, require an additional incision for its installation, or must be handled by an assistant during the surgical procedure, involving a risk of liver injury.

Aim:

The aim of this study was to evaluate and validate a technique of the esophagogastric junction exposure obtained by the flexible liver retractor in bariatric surgery, comparing its efficacy with the retractor classically used for this purpose.

Methods:

This study was performed as a randomized, open, prospective, controlled, and comparative design in patients with medical indications of bariatric surgery. The subjects were distributed in the classic (control) and flexible (test) retractor groups.

Results:

A total of 100 patients (n=50 control group, n=50 test group) were included. No statistically significant difference was observed in the mean duration of surgery. Regarding visibility, 100% of the patients in the flexible retractor group demonstrated an optimal visibility level, although without statistical significance concerning the classic retractor group (94%). Invariably, carrying a trocar was necessary when using the classic retractor.

Conclusions:

The flexible liver retractor is safe, effective, ergonomic, and inexpensive. Furthermore, it presented a satisfactory aesthetic profile, and the use of specific instruments, new adaptation curve, and training for its handling were not required.
