BACKGROUND: Sternal closure by absorbable suture material is an established method for chest closure in pediatric cardiac surgical procedures. However, the formation of granuloma around knotted suture material is frequently observed and has potential for prolonged wound healing and infection, particularly in newborns and infants. This retrospective study analyzed the suitability and reliability of a novel absorbable, self-locking, multianchor knotless suture with antibacterial technology for sternal closure in pediatric cardiac surgical procedures. METHODS: The applied material (STRATAFIX Symmetric PDS Plus, Ethicon) presents a polydioxanon (PD) suture with a self-locking, multianchor design that enables a sternal closure in a continuous knotless suture technique. All children undergoing knotless closure after standard median sternotomy were examined for the occurrence of sternal wound infection or sternal instability by applying the screening criteria of the Centers for Disease Control and Prevention at hospital discharge and at 30 and 60 days. RESULTS: The new knotless sternal closure was used in 130 patients. Patients were a mean age of 19.0 ± 31.9 months (range, 0-142 months), and mean bodyweight was 7.8 ± 6.6 kg (range, 2.4-35 kg). Delayed sternal closure occurred in 23 patients, with a mean closure time after 2.9 ± 2.6 days. One superficial incisional sternal site infection occurred, but no cases of deep sternal site infection or sternal instability were observed. CONCLUSIONS: The application of the absorbable, knotless suture technique provides excellent results regarding the rate of sternal wound infection and improved healing after median sternotomy in pediatric patients.      «
