Comparison of absorbable sutures in urinary bladder.

    Summary

    This study compared suture materials for closing cystotomy wounds in dogs. Chromic catgut showed a benign tissue reaction, while polyglycolic acid and polyglactin-910 sutures caused similar inflammatory responses in the urinary bladder.

    Area of Science:

    • Veterinary Surgery
    • Biomaterials Science
    • Surgical Pathology

    Background:

    • Suture material selection is critical for wound healing in cystotomy.
    • Understanding tissue reaction to different sutures in the urinary bladder is essential for surgical success.

    Purpose of the Study:

    • To compare the tissue reactions to polyglactin-910, polyglycolic acid, and chromic catgut sutures used in experimental canine cystotomy wounds.

    Main Methods:

    • Experimental cystotomy wounds were created in dogs.
    • Wounds were closed using polyglactin-910, polyglycolic acid, or chromic catgut sutures.
    • Tissue samples were collected and examined grossly and microscopically at 5 to 30-day intervals.

    Main Results:

    • Chromic catgut demonstrated a benign early tissue reaction.
    • Polyglycolic acid and polyglactin-910 sutures elicited similar tissue responses.
    • These reactions involved early suture fiber separation and cellular infiltration within the urinary bladder.

    Conclusions:

    • Chromic catgut is associated with a favorable early tissue response in canine cystotomy closures.
    • Polyglycolic acid and polyglactin-910 sutures induce comparable inflammatory reactions in the urinary bladder, characterized by early breakdown and infiltration.
