BACKGROUND: Surgeons are still looking for the ideal suture material, although the progress during the last decades. AIM: To compare cecorrhaphy in rats with three different sutures: polypropylene (Prolene®), polyglecaprone 25 (Monocryl®) and glycomer 60 (Monosyn®). METHOD: Seventy-two Wistar rats were divided into three groups of 24 each (polypropylene, polyglecaprone and glycomer groups). Within each group, the animals were assigned to three subgroups and assessed on the 3rd, 7th and 14th postoperative day. The parameters studied were the bursting strength, macroscopic mucosal healing, histology and tissue hydroxyproline rate. RESULTS: The bursting strength had its lower values on the 3rd postoperative day, with significant higher values on the 7th and 14th; there was no difference among groups. In the overall, the histological analysis of the inflammatory reaction, fibroblast proliferation, collagen formation, border attachment and re-epithelization showed the same pattern among the three groups and sub-groups; only on day 7, there was seen a significant higher collagen formation in polypropylene group than polyglecaprone and glycomer groups. The tissue hydroxyproline rate was significant lower in the sub-groups of the 3rd postoperative day, in all of the three studies groups, with increase on days 7 and 14. There was a parallel gain in bursting strength and neo-collagen formation. CONCLUSION: There was no difference among glycomer 60, polypropylene and polyglecaprone sutures in performing cecorrhaphy in rats between days 3 and 14, according to the evaluated parameters.
