The sandwich technique used for correction of pectus carinatum combined with Harrison sulcus

Abstract We aimed to investigate the feasibility of the sandwich technique to treat pectus carinatum combined with Harrison sulcus. We retrospectively analysed the clinical data of 38 paediatric patients with pectus carinatum combined with Harrison sulcus treated from June 2015 to October 2022. All the patients underwent surgery using the sandwich technique. The surgical conditions and postoperative outcomes of the patients and the satisfaction score of family members were analysed. Overall, the patients had a mean duration of surgery of 179.05 ± 36.01 min, intraoperative blood loss of 10.03 ± 2.77 mL, postoperative hospital stay of 6.89 ± 0.73 days, and postoperative satisfaction score of 89.4 ± 4.6. The incidence of surgical complications was 7.89%. The internal fixation stents were removed in 22 patients, and there was no recurrence during a follow-up 371.4 ± 6.3 days post-stent removal. These results were satisfactory. The use of the sandwich technique to treat this condition does not reduce the volume of the thorax after the procedure and results in an aesthetically pleasing incision, less complications, and fast postoperative recovery. Thus, it is a safe and effective method that is worthy of being promoted for clinical application.
