New BARS® study: Reduction of enlarged gastrojejunal anastomoses

BARS® achieves significant reduction of enlarged gastrojejunal anastomoses, offering a promising solution for patients with weight regain after RYGB

Key findings

• 100% technical success in all specimens
• Mean anastomotic diameter reduction of ~17.7 mm (~75 % decrease)
• Highly significant reduction from 23.7±3.38 mm to 6.0±3.86 mm (p=0.002)
• Uniform, circumferential narrowing achieved in both vertical and transverse measurements
• Reproducible results across all ex vivo models

Study details

• Type: Ex vivo pilot study
• Model: Full-thickness porcine gastric pouch with small bowel segments replicating an enlarged gastrojejunal anastomosis
• Aim: Evaluation of the efficacy of BARS® in reducing enlarged gastrojejunal anastomoses
