Vicryl is a common absorbable suture used to close the deep layers below the skin surface. It is expected to hold the tension on the deeper layers during the critical first 6 weeks of the healing period to allow less tension on the skin closure and thus a better scar.
Sometimes vicryl sutures as swell as other absorbable sutures work there way to the surface rather than dissolving deeply and can present as inflammation, redness, pain, drainage and localized infection at the suture line. Usually treatment is quite simple for a "spitting suture", involving simply removing the suture at the surface, then allowing the small opening to heal spontaneously with lots of soap and water washing.
Antibiotics are rarely needed and usually the process is well-localized so there may be no long term consequence for the scar.
