AbstractBackground and Objectives: surgery for substernal goitre is still debated in the literature, due to the wide range of surgical options. This article outlines the findings of our extensive experiences, which include 264 cases of patients with “goitre plongeant“, and compares postoperative complications, despite surgical approaches. Material and Methods: preoperative planning and anatomical landmarks are described to determine the potential need of a combined approach. The surgical procedure is described, along with some stratagems, to ensure that the operation is completed safely. A statistical analysis of complications and the length of stay, with a comparison of cervicotomy and combined access, was performed using the Pearson chi-square significance test. Results: 264 patients underwent thyroid surgery for substernal goitre. The Kocher incision was the surgical approach chosen in 256 patients (96.6%), while an accessory incision was performed in 8 patients (3.4%). The necessity to use a two-fold surgical access was linked to a higher rate of postoperative complications (p-value < 0.01). The average length of stay (LOS) for cervicotomy was 2 days (1−3 days), while the average LOS was 5 days (4−7 days) (p-value = n.s.) for combined access. Conclusions: cervicotomy should be the gold standard technique for exploring intrathoracic goitre with a digital dissection, which, in almost all cases, enables the externalization of the mediastinal portion associated. Sternotomy is related to a higher rate of complications, so it should be performed only in selected cases. Management in large-volume centres may be more appropriate.
