Comparison of absorbable sutures in urinary bladder

Experimental cystotomy wounds in dogs were closed with sutures of polyglactin-910, polyglycolic acid, and chromic catgut. Animals were sacrificed at intervals of five to thirty days, and wounds were examined grossly and microscopically. This study reconfirms the benignity of early tissue reaction to catgut and points out the similarity of tissue reaction to polyglycolic acid and polyglactin-910 suture in the urinary bladder, the reaction characterized by early separation and invasion of suture fibers by cellular infiltration.
