Esophageal transection using a biofragmentable anastomosis ring in dogs

Area of Science:

• Surgical Innovation
• Gastroenterology
• Veterinary Surgery

Background:

• The biofragmentable anastomosis ring (BAR) has been successfully used in various gastrointestinal anastomoses since 1985.
• Previous studies support the safety and efficacy of BAR in bowel and other digestive tract surgeries.

Purpose of the Study:

• To investigate the feasibility and safety of using the BAR for esophageal transection in a canine model.
• To evaluate the BAR's performance in a challenging surgical site.

Main Methods:

• Esophageal transection was performed using the BAR in seven dogs.
• Postoperative monitoring included observation for complications and assessment of ring disintegration.
• Necropsy and histological examination were conducted on postoperative day 28.

Main Results:

• Five of seven dogs recovered uneventfully; two deaths were attributed to technical errors unrelated to the BAR.
• The BAR successfully facilitated esophageal transection without leakage or significant stenosis.
• Ring fragments were passed in feces between postoperative days 14 and 21.

Conclusions:

• The biofragmentable anastomosis ring (BAR) is a feasible and safe option for esophageal transection.
• BAR offers an easy-to-learn, time-saving surgical technique for esophageal operations.
• Further research may validate BAR for human esophageal surgery.
