A Prospective Multicenter Standard of Care Study of Outpatient Laparoscopic Sleeve Gastrectomy

Abstract

A global shift is occurring as hospital procedures move to ambulatory surgical settings. Surgeons have performed outpatient sleeve gastrectomy (SG) in bariatric surgery since 2010. However, prospective trials are needed to ensure its safety before widespread adoption.

Purpose: The study aimed to present a comprehensive report on the prospective data collection of 30-day outcomes of outpatient primary laparoscopic SG (LSG). This trial seeks to assess whether outpatient LSG is non-inferior to hospital-based surgery in selected patients who meet the outpatient surgery criteria set by the American Society for Metabolic and Bariatric Surgery.

Materials and methods: This study is funded by the Society of American Gastrointestinal and Endoscopic Surgeons and has been approved by the Advarra Institutional Review Board (Pro00055990). Cognizant of the necessity for a prospective approach, data collection commenced after patients underwent primary LSG procedures, spanning from August 2021 to September 2022, at six medical centers across the USA. Data centralization was facilitated through ArborMetrix. Each center has its own enhanced recovery protocols, and no attempt was made to standardize the protocols.

Results: The analysis included 365 patients with a mean preoperative BMI of 43.7 ± 5.7 kg/m2. Rates for 30-day complications, reoperations, readmissions, emergency department visits, and urgent care visits were low: 1.6%, .5%, .2%, .2%, and 0%, respectively. Two patients (0.5%) experienced grade IIIb complications. There were no mortalities or leaks reported.

Conclusion: The prospective cohort study suggests that same-day discharge following LSG seems safe in highly selected patients at experienced US centers.
