In summary, there are just two manuscripts reporting cases of attempted laparoscopic conversion of JIB to RYGB with its modern anatomical construction. However, a one stage procedure has not been achieved up to date. Therefore, no outcomes with this approach have been documented as well. With this study, we will advance our knowledge about revision bariatric surgery and report excellent outcomes after conversion from a completely malabsorptive procedure to a mostly restrictive weight loss procedure, the gastric bypass and although JIB was abandoned long time ago, there are still living patients with this procedure and bariatric surgeons need to be aware of side effects and minimally invasive strategies for the management of these highly complex patients.
