Comparison of continuous intradermal with simple interrupted suture pattern: an experimental study in dogs

Abstract

The aim of the study was to compare incisional wound healing in intradermal and simple interrupted suture patterns. Ten dogs were included. Surgically created skin incisions were apposed with (a) continuous intradermal pattern, (b) simple interrupted pattern, [both with 3/0 poliglecaprone 25], and (c) continuous intradermal pattern with 4/0 poliglecaprone 25. Cosmetic, clinical and histologic scores were evaluated. Simple interrupted sutures required significantly less time than intradermal sutures to complete. Cosmetic evaluation scoring was not statistically significant among the techniques. Irrespectively of the technique, the cosmetic, clinical and histologic appearance of the incisions improved over time. The cosmetic and histologic differences between the techniques were large during the first month, but decreased latter, whereas clinical differences persisted. The clinical appearance of the intradermal pattern was initially very good, worsened during the second postoperative month, and improved afterwards. Intradermal pattern with 4/0 poliglecaprone 25 was superior in terms of cosmetic, clinical and histologic appearance compared to simple interrupted pattern and to intradermal pattern with 3/0 poliglecaprone 25 for skin closure in dogs. © 2020 Elsevier Inc.
