The Biofragmentable Anastomosis Ring (BAR) shows comparable healing to sutures and staplers in colonic surgery, with similar recovery times and hospital stays. BAR also proved effective in small bowel and gallbladder surgeries without complications.

Area of Science:

  • Gastroenterology
  • Surgical Innovation
  • Medical Devices

Background:

  • The Biofragmentable Anastomosis Ring (BAR) was developed for sutureless large bowel anastomoses.
  • Sutured and stapled anastomoses are current standards for bowel reconstruction.

Purpose of the Study:

  • To evaluate the efficacy and safety of the Biofragmentable Anastomosis Ring (BAR) in comparison to traditional sutured and stapled anastomoses.
  • To explore new clinical applications of the BAR in small bowel and cholecystojejunostomy procedures.

Main Methods:

  • Experimental surgery in 14 dogs comparing BAR, manual suture, and circular stapler for colonic anastomoses.
  • Clinical trials involving 150 patients for colonic surgery and 170 patients for upper gastrointestinal surgery, randomizing BAR versus sutures.

Related Experiment Videos

  • Late results evaluated radiologically and endoscopically in 26 patients with previous BAR colonic anastomoses.

    • Main Results:

    • In dogs, all anastomosis types healed well by day 40, though BAR showed transient mucosal inflammation.
    • Clinical colonic surgery: BAR and suture groups had similar rates of anastomotic leakage (2/79 vs. 3/71) and stricture (1/79 vs. 1/71).
    • Upper GI surgery: BAR enteroanastomoses (81 patients) and sutured enteroanastomoses (89 patients) showed no ruptures or obstructions.

    Conclusions:

    • The Biofragmentable Anastomosis Ring (BAR) is a safe and effective alternative for colonic anastomoses, yielding results comparable to sutured and stapled methods.
    • BAR demonstrates successful application in small bowel and biliary tract reconstructions, with no observed complications.
    • Long-term evaluation indicates BAR anastomoses are durable, with many becoming radiologically and endoscopically undetectable over time.
