Background:
Laparoscopic gastric bypass is gold-standard for morbid obesity treatment.
Aim:
To describe the results of robotic gastric bypass for morbid obesity patients.
Method:
Were operated on 100 morbidly obese patients through totally robotic gastric bypass between 2013 and 2014. They were 83% female. The age ranged from 20 to 65 years old (medium 48,5 years); the body mass index varied between 38-67 (medium 42,3 kg/cm2). The procedure was designed with 3 cm long gastric pouch, 1 m biliopancreatic limb, 1,2 m alimentary limb, manual or stapled anastomosis. There were four super-super-obese patients and four revisional surgeries.
Results:
Docking time varied from 1 to 20 min (medium 4 min). Console time varied from 40-185 min (medium 105 min). There were no intra operative complications or mortality. There were two lower limb deep venous thrombosis. There was no readmission in the first 30 days.
Conclusion:
Totally robotic gastric bypass is safe and reproduceable, with excellent results even during the initial experience with regular surgeries, revisional surgeries or in super-obese patients. Adequate training may shortens or obviates the learning curve.
