Clinical comparison study of VATS anterior mediastinal tumor resection through approach of trans-subsagittal incision and trans-intercostal incision / 中华胸心血管外科杂志

ABSTRACT

Objective:To compare the clinical effect of anterior mediastinal tumor resection with video assisted thoracoscopic surgery(VATS) through approach of trans-subsagittal incision and trans-intercostal incision.Methods:The clinical data of 118 patients including 67 males and 51 females with anterior mediastinal tumors using VATS resection from January 2013 to October 2020 in Tongren Hospital, Shanghai Jiao Tong University School of Medicine were analyzed retrospectively. According to different incisional approach, these patients were divided into two groups of trans-subsagittal incision group including 45 cases with 25 males and 20 females, and trans-intercostal incision group including 73 cases with 42 males and 31 females. The sternal incision group was treated with the sub xiphoid incision plus the subcostal arch incision and the sternal retractor traction sternum, and the intercostal incision group was treated with the traditional intercostal space incision. Subsagittal incision combined subcostal arch incision and sternum traction with sternal retractor was used in the approach of trans-subsagittal incision group, and the traditional thoracotomy was used in the intercostal incision group. The clinical data of operation time, volume of intraoperative blood loss, rate of transfer to open thoracotomy, duration of postoperative chest tube drainage, visual analogy score(VAS)assessed on the 1st and 3rd days after surgery, hospitalization time, average cost of hospitalization, and incidence of postoperative complications, were compared between the two groups.Results:The operative time, volume of intraoperative blood loss, the number of cases of transfer to open thoracotomy, duration of postoperative chest tube drainage, VAS score of the first and third days after operation, length of hospitalization, average hospitalization cost and the incidence of postoperative complications were lower than those in the transcostal incision group( P<0.05). Conclusion:Compared to the group of trans-intercostal incision VATS resection of anterior mediastinal tumor, the trans-subsagittal incision group has many advantages as follows, shorter operation time, less intraoperative blood loss, no transfer to open thoracotomy, much simpler and safer operative procedure, less body trauma, lighter postoperative pain, less postoperation complications, shorter hospitalization time, less average hospitalization cost, and rapid rehabilitation after surgery.
