This will be a prospective, obesity-registry based, single-blind randomized controlled trial with a 1:1 allocation ratio. Specific inclusion criteria are all patients eligible to undergo a Laparoscopic sleeve gastrectomy (LSG) based on the current National Institute of Health (NIH) patient selection guidelines. Patients should be able to give consent, be deemed medically-cleared to undergo elective surgery, and tolerate general anesthesia. All enrollments and surgeries in this study will take place at the Cleveland Clinic Bariatric and Metabolic Institute. The study will consist of 2 interventions: laparoscopic sleeve gastrectomy (LSG) or robotic sleeve gastrectomy (RSG). The primary objective is early postoperative pain, but also surgeon ergonomics and patient quality of life will be compared. Additional outcomes include 30-day perioperative results, minor and major morbidities, serious adverse events, resolution of medical comorbidities, and weight loss in percent of excess weight lost (%EWL) at one year.
