Prevention of Postoperative Nausea and Vomiting After Bariatric Surgery

Patients with obesity or morbid obesity who are scheduled to undergoing robotic or laparoscopic sleeve gastrectomy will be screened at their preoperative visit. If they meet inclusion/exclusion criteria, they will be invited to participate in the study and written informed consent will be obtained. If the patient consents to participation, they will be randomized to either the control arm or intervention arm. All patients will undergo sleeve gastrectomy in a standard fashion, either laparoscopically or robotically, as discussed with their bariatric surgeon. Post-operative diet will be initiated 4 hours after surgery. The specific diet received will depend on which arm the patient is randomized into. Post-operative assessments will be completed at various time points for all patients. These include a Verbal Rating Scale of Nausea and Vomiting, Rhodes Index Survey, and Quality of Recover-15 Survey. All patients will track their oral intake on a spreadsheet which will be provided. Additional demographic and clinical data will be collected from the Electronic Medical Record. After hospital discharge, patients will follow up in the clinic one week and one month after surgery, per routine. After the one-month visit, the patient's study participation will be considered complete.
