Purpose: The present study discussed the effects of accidental parathyroid resection on hypoparathyroidism and investigated the risk factors associated with accidental parathyroid resection.
Methods: Clinical data from patients who have undergone thyroidectomy at a university hospital in the period from November 2018 and October 2020 were entered into the database and analyzed. Risk factors for accidental parathyroid resection were recorded.
Results: A total of 1775 cases were included in this study. The analysis showed that lymph-node dissection (p < 0.001), T staging (p = 0.037), and treatment group (p < 0.001) were independent risk factors for accidental parathyroid resection. Different treatment groups were important risk factors for accidental parathyroid resection. There were significant differences between the professional and non-professional groups in the following aspects: accidental parathyroid resection (p < 0.001), Scope (p < 0.001), T stage (p = 0.009), N stage (p < 0.001), range of lymph-node dissection (p < 0.001), number of lymph nodes dissected in central area (p < 0.001), and number of lymph-node metastases in the central region (p < 0.001).
Conclusions: The causes of accidental parathyroid resection are multifactorial. The predictors for accidental parathyroid resection include lymph-node dissection in the central region, T staging, as well as the operating surgeons' experience.
