Same-day discharge after bariatric surgery is on the rise, but a new systematic review reveals a major catch — nearly every study defines patient eligibility and discharge readiness differently. Analyzing 41 studies across 15 countries and nearly 2 million patients, researchers found the inconsistency so severe that pooling results was impossible. Experts are now calling on international surgical societies to establish standardized criteria.
Same-day discharge after metabolic bariatric surgery (MBS) is becoming increasingly common under enhanced recovery protocols — but a new systematic review reveals the field is operating without a shared rulebook. Researchers analyzed 41 studies from 15 countries covering nearly 2 million patients and found that virtually every study used its own unique definitions for who qualifies for same-day discharge and what "ready to go home" actually means.
The heterogeneity was so extreme — 95% of studies used unique inclusion criteria, 94% unique exclusion criteria, and 100% unique discharge definitions — that a meta-analysis was deemed impossible. While most studies shared broad underlying concepts (like age, weight, and anesthesia risk), the specific thresholds varied widely, making cross-study comparisons unreliable.
By the Numbers:
Why it matters: Without standardized criteria, it's nearly impossible to know whether same-day bariatric discharge is truly safe or just selectively reported. International surgical societies (ASMBS, IFSO, EAES) are being urged to develop consensus-based standards — separately for sleeve gastrectomy and anastomotic procedures — to enable reliable, comparable evidence going forward.
