Background:
Single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S), is an effective weight-loss surgery for clinically severe obesity and has established safety profiles in inpatient hospital settings. However, its safety in outpatient settings with same-day discharge remains unexplored.
Objective:
The study aimed to evaluate the short-term safety and complication profile of primary SADI-S procedures performed in outpatient settings across multiple centers.
Methods:
A retrospective analysis was performed using data from a prospectively maintained database, encompassing 327 instances of outpatient primary SADI-S procedures conducted between May 2020 and January 2023. Six surgeons performed these procedures at three distinct U.S. surgical centers. No standardized surgical techniques or enhanced recovery after surgery protocols were uniformly applied across these centers.
Results:
A total of 327 patients were included in the final analysis. The mean preoperative BMI was 45.2 ± 7.2 kg/m2. Preoperative obstructive sleep apnea (26.2%), hypertension (25.3%), gastroesophageal reflux disease (22%), hyperlipidemia (18.9%), and type 2 diabetes (16.2%) were observed in the patient cohort. Intraoperative complications occurred in .3% of cases, with no instances of open conversion. The mean skin-to-skin operative time was 65.2 ± 24.6 min, and the average length of stay was 5 h and 7 min ± 2 h. The 30-day rates of complication, reintervention, ER visits, readmissions, and reoperations were 3.6%, 1.8%, 1.5%, .9%, and .9%, respectively.
Conclusion:
In carefully selected patients, outpatient SADI-S was associated with favorable short-term safety outcomes, including low rates of complications, reinterventions, and readmissions, suggesting feasibility in specialized centers pending further prospective validation.
