OBJECTIVE: To evaluate the multitude of new synthetic absorbable sutures (both monofilament and multifilament) in comparison with older materials with regard to capillarity and bacterial transport. METHODS: Sutures of United States Pharmacopoeia (USP) 4-0 thickness were arranged in a three-chamber system under sterile conditions. Either a colorant (liquid transport evaluation) or bacteria (bacterial transport evaluation) were added to the contamination chamber, and movement of colorant or bacteria was evaluated for as long as 30 days. RESULTS: None of the monofilament sutures transported colorant or bacteria. Colorant transport was found on the pseudomonofilament and multifilament sutures between the first and the fifth day. Escherichia coli were transported on the majority of the multifilament sutures, although no transport was found on silk or polyester sutures. Bacterial transport was most often evident in tests using the motile Proteus mirabilis. CONCLUSIONS: All multifilament and pseudomonofilament suture designs allowed transport of colorants and bacteria to some degree. The movement of fluids and bacteria did not depend on the absorptive capacity of the sutures, coating, or the presence of an open suture end.
