Abstract

Background: Ambulatory bariatric surgery has recently gained interest especially as a potential way to improve access for eligible patients with severe obesity. Building on our previously published research, this follow-up study delves deeper in the evolving landscape of ambulatory bariatric surgery over a 3-year period, focusing on predictors of success/failure.

Methods: In a prospective single-center follow-up study, we conducted a descriptive assessment of all eligible patients as per our established protocol, who underwent a planned same-day discharge (SDD) primary sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) between 03/01/2021 and 02/29/2024. Trends in SDD surgeries over time were assessed over six discrete 6 month intervals. Primary endpoint was defined as a successful discharge on the day of surgery without emergency department visit or readmission within 24 h. Secondary outcomes included 30-day postoperative morbidity.

Results: A total of 811 primary SG and 325 RYGB procedures were performed during the study period. Among them, 30% (n = 244) were SDD-SGs and 6% (n = 21) were SDD-RYGBs, respectively. At baseline, median age of the entire SDD cohort was 43 years old, 81% were females, and body mass index (BMI) was 44.5 kg/m2. The planned SDD approach was successful in 89% after SG (n = 218/244) and in 90% after RYGB (n = 19/21). Nausea/vomiting was the main reason for a failed SDD approach after SG (46%). The 30-day readmission rate was 1.5% (n = 4) for the entire SDD cohort including only one readmission in the first 24 h. The percentage of SDD-SGs performed as a proportion of total SGs increased over the initial five consecutive six-month intervals (14%, 25%, 24%, 38%, and 49%).

Conclusion: Our SDD protocol for bariatric surgery demonstrates a favorable safety profile, marked by high success rate and low postoperative morbidity. These outcomes have led to a continued increase in ambulatory procedures performed over time especially SG.
