Comparison between the effects Dexon Plus (Covered Polyglycolic Acid) and Maxon (Monothreaded Polyglyconate) on the intestinal healing ileal surgeries. Experimental study in dogs (Canis familiaris, Linnaeus, 1758)

Abstract

Absorbable synthetic suture threads were compared. Dexon Plus and Maxon were studied in ileal surgeries in dogs. Trials were conducted in 9 animals, and evaluation protocols comprised macro and microscopic studies at days 2, 10 and 30 postsurgery. Results showed that at day 2 after surgery, compared to Maxon. Dexon Plus caused significant infiltration of polymorphonuclear neutrophils and necrotic areas. At day 10 it was found, comparatively to Maxon, that the cellular infiltrate showed marked decrease, being replaced by mononuclear cells and fibroblasts, trending to organization. In spite of the differences found in the initial and intermediate phases, in the late phase results were similar for both materials. There was a marked decrease of the iflammation process, intense fibroblast proliferation and a tendency to "point granulomae" formation.
