Abstract:
Objective:To investigate the effects of antibacterial absorbable suture closure in the repair of small range of bone defect wounds due to deep sternal wound infection after median thoracotomy.Methods:This study was a retrospective non-randomized clinical controlled study. A total of 32 patients (20 males and 12 females, aged (58±11) years) who met the inclusion criteria and underwent closure with antibacterial absorbable sutures (hereinafter referred to as direct closure surgery) admitted to Guangdong Provincial People's Hospital of Southern Medical University (hereinafter referred to as our hospital) from October 2017 to December 2021 were included in direct closure group. A total of 39 patients (27 males and 12 females, aged (59±11) years) who met the inclusion criteria and received bilateral pectoralis major muscle flap packing repair admitted to our hospital from January 2015 to January 2020, were included in muscle flap packing group. In the two groups, sternal infected wounds were thoroughly debrided during stage Ⅰ surgery, followed by wound repair during stage Ⅱ surgery. The width of sternal cross-section defects after debridement was less than 1 cm for patients in the two groups. For patients in direct closure group, stage Ⅱ wound repair involved intermittent sutures to the anterior sternal plate or full-thickness sternum with a total of 6 or 7 double sternal sutures. Relevant data including the duration of the stage Ⅱ wound repair surgery and the volume of blood loss during surgery, length of hospital stay, and bacterial wound infection of patients in the two groups were recorded. The postoperative complications and wound healing of patients in the two groups were recorded. During follow-up, the wound infection or recurrence of patients in the two groups and the sternal healing of patients in direct closure group were observed.Results:Compared with those in muscle flap packing group, the duration of stage Ⅱ wound repair surgery and length of hospital stay of patients in direct closure group were significantly shorter (with t values of 13.61 and 6.25, respectively, P<0.05), and there was no statistically significant difference in intraoperative blood loss volume of the stage Ⅱ wound repair surgery between the two groups ( P>0.05). The main bacterial infection in the two groups was Staphylococcus. In direct closure group, one patient had exudation in the wound two weeks post-operation, however the wound healed well after two weeks of conservative dressing changes; the wounds of the other patients healed well. In muscle flap packing group, 5 patients had postoperative complications, of which one patient died, and the wounds of 4 patients healed after dressing change or reoperation; the wounds of the other patients healed well. There was no statistically significant difference in complication incidence of patients between the two groups ( P>0.05). During the follow-up of 22-45 months, there was no re-infection or recurrence in the wound of patients in direct closure group and surviving patients in muscle flap packing group, the sternum of patients in the direct closure group achieved anatomical union. Conclusions:Direct closure surgery can not only effectively repair sternal cross-sectional defects with width below 1 cm due to deep sternal wound infections after median thoracotomy, but can also significantly shorten the operation time and duration of hospitalization.
