Meta-analysis of leak following sleeve gastrectomy
“Patients in whom synthetic PGA/TMC staple line reinforcement material was applied during LSG had no postoperative leaks or hemorrhages from the staple line. The differences in leak rate between the reinforcement-material group and the no-reinforcement-material group was significant (p=0.045).” – Durmush et al.3
Use of [GORE® SEAMGUARD® Bioabsorbable Staple Line Reinforcement] to prevent pancreatic leak following distal pancreatectomy
“The use of [GORE® SEAMGUARD® Bioabsorbable Staple Line Reinforcement] is quickly becoming a common adjunct in distal pancreas resections. Our study shows a lower incidence of pancreatic leak after distal pancreatectomy with the use of this staple line reinforcing product.” –Imagawa et al. 4
Reduction in Bleeding
Staple line reinforcement was developed more than a decade ago in an effort to strengthen the integrity of the staple line and minimize bleeding. Staple line reinforcement employs a buttressing material that strengthens the staple line and provides a compressive effect on the staple line, leading to improved hemostasis.
Our study shows that GORE® SEAMGUARD® Bioabsorbable Staple Line Reinforcement is effective in decreasing bleeding complications related to the long staple line associated with LVSG. Chiasson et al5
Miller et al.6 showed significantly reduced bleeding in gastric bypass procedures (p<0.05)*
- Lower mean blood loss
- Fewer staple line bleeding sites
- Less time to staple line hemostasis
Nguyen et al.7 showed significantly reduced bleeding in gastric bypass procedures (p<0.05)*
- Less clips used
- Higher post-op hemoglobin
Consten et al.8 showed significantly reduced bleeding in gastric bypass procedures (p<0.05)*
- Lower mean blood loss
