Cost-Effectiveness and Outcome of Robot-assisted Vs Laparoscopic Roux-en-Y Gastric Bypass

Cost-Effectiveness and Outcome of Robot-assisted Vs Laparoscopic Roux-en-Y Gastric Bypass: A Non-inferiority Randomized Controlled Trial

The objective of this randomized controlled trial is to compare perioperative outcomes between laparoscopic and robotic approaches in patients with severe obesity who are candidates for RYGB. The trial aims to address the following key questions:

To evaluate the difference between the two procedures in terms of postoperative complications.

To assess intraoperative complications, conversion rate, mortality, operative times, postoperative hospital stay, and cost analysis for both approaches.

In summary, the researchers will compare the laparoscopic and robotic approaches to determine which one leads to better perioperative outcomes

Treating patients with pathological obesity has always posed a challenge for bariatric surgeons due to their increased risk of post-operative complications and varying short-term outcomes depending on the chosen procedure. Currently, there are no established guidelines to dictate which procedure is optimal for a given clinical presentation. Surgeons typically make this decision based on their expertise and the patient's characteristics. The most frequently performed procedures worldwide are sleeve gastrectomy and Roux-en-Y gastric bypass, with the latter validated by numerous long-term studies as a safe and effective bariatric and metabolic option for patients with a BMI <50 kg/m2. However, the complexity of Roux-en-Y gastric bypass, which requires the creation of two anastomoses during the reconstruction phase, which might be challenging when performed laparoscopically, may be facilitated by a robotic approach. Although some studies suggest that these approaches have equivalent safety and efficacy profiles, conclusive evidence evaluating their economic impact remains elusive. Consequently, the objective of the present study is to compare morbidity between the laparoscopic and robotic approach in patients undergoing Roux-en-Y gastric bypass.

Inclusion Criteria:

• Age 18 years or older
• Patients who are candidates for Roux-en-Y gastric bypass using a minimally invasive technique
• Informed consent has been given.

Exclusion Criteria:

• patients who are candidates for bariatric procedures other than Roux-en-Y gastric bypass, or to those who require a laparotomy for Roux-en-Y gastric bypass surgery.
