Higher leak rates after repeat sleeve gastrectomy compared to first sleeve surgery or gastric bypass conversion

1.3% of patients who underwent re-sleeve experienced staple line leaks, significantly higher than the 0.1% in primary sleeve gastrectomy.

• Re-sleeve surgery is associated with longer operative times, averaging 90.16 minutes compared to 68.32 minutes for primary sleeve gastrectomy.
• Patients undergoing re-sleeve had higher rates of readmissions (5.5% vs. 2.1%), reoperations (2.3% vs. 0.6%), and interventions (2.5% vs. 0.4%) compared to primary sleeve gastrectomy.
• In comparisons of re-sleeve to conversion from sleeve gastrectomy to Roux-en-Y gastric bypass, re-sleeve also showed higher staple line leak rates (1.3% vs. 0.5%).
• The study indicates a 2.6-fold increase in staple line leaks after re-sleeve compared to conversion to Roux-en-Y gastric bypass.
• There is a 13-fold increase in staple line leaks after re-sleeve compared to primary sleeve gastrectomy.
