Autologous, free omentum grafts for large, open, distal limb wounds in dogs: Technique and outcome in 10 dogs.

Abstract

Objective: To describe the operative technique and outcome of free autologous omentum grafting (OG) for wound reconstruction on the distal limbs of dogs.

Study design: Retrospective case series.

Animals: A total of 10 client-owned dogs.

Methods: Medical records (2010-2023) were searched for dogs with open limb wounds distal to the stifle or elbow treated with OG for wound reconstruction. OG was harvested via celiotomy, then sutured to the wound bed and 0.4-1 cm subcutaneous tissue beneath surrounding dermis. Wounds were bandaged using a petroleum-coated primary layer to prevent graft desiccation for 1-2 weeks. Using ImageJ software, wound area and final unhaired scar area were analyzed and time to epithelialization, major and minor complications, and length of follow up were determined.

Results: Dogs with a mean age of 6.9 ± 4.2 years were identified with wounds (n = 13 wounds) measuring 25.96 ± 16.27 cm² at the time of OG. Wounds were healed in 59.5 ± 11.1 days. Minor complications included infection and swelling/discharge in two and 10 dogs, respectively. There were no major complications. By 30-days postoperatively, wounds were 18.85 ± 0.1% of the original size. All wounds healed with complete epithelialization, excellent cosmesis, no lameness and partial to complete hair regrowth.

Conclusion: OG may provide an alternative method for management of distal limb wounds in dogs, with minimal complications, excellent cosmesis and functional outcomes in 10 dogs.

Clinical significance: Free OG may offer an alternative method of wound management in dogs; however, further research with controlled prospective studies is indicated before recommending the method over other treatment options.
