Satisfaction rate of patients undergoing sleeve gastrectomy as day-case surgery compared to conventional hospitalization: a prospective non-randomized study

Purpose Day-case surgery (DCS) has boomed over recent years. However, day-case bariatric surgery remains controversial due to a lack of evaluation. The objective of this study was to compare the experiences and satisfaction with general anesthesia of patients undergoing sleeve gastrectomy (SG) as DCS compared to conventional hospitalization. Methods Between January 2015 and June 2016, all patients undergoing primary SG as day-case surgery or with conventional hospitalization were prospectively included in this non-randomized, non-inferiority study comparing the level of satisfaction of patients undergoing SG with conventional hospitalization (CH group, gold standard) versus SG as DCS (DCS group). The primary efficacy endpoint was comparison of the overall satisfaction rate using the EVAN-G questionnaire. The secondary endpoints were evaluation of the 6 dimensions of the EVAN-G questionnaire, discharge from hospital, adhesion with SG management and overall satisfaction with SG. Results One-hundred and twenty-four patients met the inclusion criteria (62 in both groups). The DCS group was younger with fewer comorbidities (p <= 0.01) and had a lower BMI (p <= 0.01). Overall, the mean EVAN-G questionnaire score was 66.4 (63.9-68.9) for the DCS group and 68.9 (65.9-71.8) for the CH group (non-inferiority of DCS group). In the DCS group, 19% of patients would have preferred to spend the night in hospital, while 82% of patients in the CH group would have preferred DCS and a total of 75% of patients reported a high level of satisfaction. Conclusion Overall satisfaction of patients undergoing SG as day-case surgery was not inferior to that of patients managed by conventional hospitalization.
