Summary

The biofragmentable anastomosis ring (BAR) offers a safe and fast method for intestinal surgery. This study shows BAR significantly reduces anastomosis time with a low leakage rate, simplifying surgical procedures.

Area of Science:

  • Surgical Innovation
  • Gastrointestinal Surgery
  • Biomaterials

Background:

  • Intestinal anastomosis is a critical surgical procedure.
  • Conventional hand-sutured anastomosis can be time-consuming and prone to complications.
  • Biofragmentable anastomosis ring (BAR) offers a novel approach.

Purpose of the Study:

  • To evaluate the safety, efficacy, and time efficiency of the biofragmentable anastomosis ring (BAR) in intestinal anastomosis.
  • To compare BAR-assisted anastomosis with conventional hand-sutured techniques.

Main Methods:

  • Prospective study involving 40 patients undergoing intestinal anastomosis using BAR.
  • Data collected on operative time, technical challenges, fragmentation, excretion, and anastomotic complications.

  • Comparison of operative time with 23 cases of conventional hand-sutured anastomosis.

    • Main Results:

    • 43 BAR anastomoses performed in 40 patients across various bowel resections.
    • Mean operative time for BAR anastomosis was 15.2 minutes, significantly shorter than conventional methods.
    • Low anastomotic leakage rate of 2.5% (1/40), with fragmentation and excretion occurring between 14-49 days.

    Conclusions:

    • Intestinal anastomosis using BAR is a simple, safe, and fast surgical technique.
    • BAR facilitates efficient colonic and small intestinal anastomosis with minimal complications.
    • The device fragments and is excreted naturally within weeks post-surgery.
