Prospective Robotic-assisted Revisional Bariatric Study

A Prospective Multicenter Study to Evaluate the Perioperative Outcomes of Robotic-assisted Revisional Bariatric Surgery

Very few studies have compared robotic-assisted (RRBS) versus laparoscopic revisional bariatric surgeries (LRBS). To date, there has not been a prospective study comparing the perioperative outcomes of patients undergoing robotic-assisted and laparoscopic revisional bariatric surgery. This study aims to enroll patients undergoing RRBS and LRBS and evaluate the outcomes through 45 days, including the perioperative period. We hypothesize that RRBS may be associated with lower rates of perioperative outcomes.

Inclusion Criteria:

1. Subject is 18 years or older at the time of consent
2. Subject has a history of prior bariatric surgery
3. Subject's revisional procedure will be either laparoscopic revisional bariatric surgery (LRBS) or robotic-assisted revisional bariatric surgery (RRBS)
4. Subject undergoes revisional bariatric surgery that is applicable to study

Exclusion Criteria:

1. Subject is undergoing a primary bariatric procedure
2. Subject has undergone more than one previous bariatric procedure
3. Subject's revisional bariatric procedure is an emergent procedure
4. Subject is contraindicated for general anesthesia or surgery
5. Subject is unable to comply with the follow-up visit schedule
6. Subject is pregnant or suspects pregnancy
7. Subject is mentally handicapped or has a psychological disorder or severe systemic illness that would preclude compliance with study requirements or ability to provide informed consent
8. Subject belonging to other vulnerable population, e.g, prisoner or ward of the state
