- Conversion of vertical banded gastroplasty (VBG) to Roux-en-Y gastric bypass (RYGB) are often a surgical challenge.

- Main indications for revision can be weight regain with persistent comorbidities or complications as reflux or dysphagia.

- Dissection of the vertical banded gastroplasty and the release of adhesions due to previous laparotomy can be tricky.

- The robotic approach is of real interest in revisional surgery, facilitating technical difficulties and increasing safety.
