Background: Globally, the incidence of severe obesity and the comorbidities that it causes has increased. A patient who undergoes day-case surgery (DCS) is admitted and released the same day. The practicality and safety of using DCS during laparoscopic sleeve gastrectomy (LSG) and one anastomosis gastric bypass (OAGB) procedures have already been discussed and are almost established. As of yet, no studies have looked into this problem for OAGB. Objective: The present study aimed to evaluate the safety and feasibility of DC-OAGB in the Egyptian community and to compare it with DCS-LSG. Patients and methods: This is a prospective non-randomized controlled clinical trial that was conducted on 100 patients scheduled for bariatric surgery. Patients eligible for day-case surgery were included. The study patients were non-randomly equally allocated to the DC-LSG group or the DC-OAGB group. Patients' operative data were recorded. They were followed by telephone for 4 days, and were followed again 15 days and 1 month later, and their satisfaction with DC bariatric surgery was assessed.  Results: There was an equal same-day discharge rate (96%) in both groups. The total readmission rate was 1%, while for DC-LSG and DC-OAGB separately; the rates were 2% and 0%, respectively. The patients in the current study presented a high satisfaction rate. No statistically significant differences were found between the two groups in the postoperative outcome. Conclusion: DC-OAGB as well as DC-LSG showed feasibility and safety. Patients for the DCS should be properly selected to avoid elevated morbidity and mortality rates. Patients were highly satisfied with the DCS protocol.
