Acute gastric leaks following laparoscopic sleeve gastrectomy are serious complications with significant mortality risk. This report highlights that using large esophagoduodenal megastents achieves over 90% success in treating these leaks, outperforming conventional smaller stents with success rates of 50–73%. Rapid and effective source control of infection is critical to prevent sepsis and improve patient outcomes.
Background
Gastric leaks after sleeve gastrectomy typically occur within the first two weeks postoperatively and represent a life-threatening complication with mortality rates up to 3.7%, rising to 35% in severe sepsis cases. Early diagnosis and management are essential to prevent progression to septic shock. Conventional fully covered esophageal stents have shown moderate success but may be insufficient in acute leaks. Differentiating acute/early leaks from late/chronic fistulae is important as their pathophysiology and treatment responses differ significantly.

Key Findings
Acute/early gastric leaks occur on average 9.6 ± 7.3 days after sleeve gastrectomy and require urgent intervention.
Megastents provide significantly higher success rates (>90%) compared to conventional stents (50–73%) in treating acute leaks.
Stent migration occurs in approximately 30% of megastent cases but can be managed endoscopically without severe clinical consequences.
Meta-analyses including both acute and chronic leaks, or different bariatric procedures, have limited applicability to acute sleeve gastrectomy leaks.
Rapid, simple, and standardized treatment algorithms using megastents improve efficiency and patient safety in acute leak management.
Clinical Implications
For patients presenting with acute gastric leaks after sleeve gastrectomy, prompt placement of a large esophagoduodenal megastent should be considered the preferred treatment to maximize leak closure success and reduce mortality risk. Clinicians should prioritize rapid source control over complex individualized algorithms to prevent sepsis. While stent migration is common, it is manageable and does not outweigh the benefits of megastent use.
Conclusion
Acute gastric leaks after sleeve gastrectomy demand rapid and effective intervention. The use of large esophagoduodenal megastents offers superior success rates and a streamlined treatment approach, supporting the principle that in this context, 'the bigger, the better.'
