The Clinical Analysis of Preventable Reoperation for Primary Hyperparathyroidism

Objective To discuss the diagnosis,preoperative imaging and surgical technique of patients who underwent reoperation for persistent hyperparathyroidism.Methods A prospective database about primary hyperparathyroidism in Department of General Surgery,Peking Union Medical College Hospital was searched for the patients who underwent reoperation for persistent hyperparathyroidism from January 2009 to December 2016.The information about the initial operation,preoperative imaging study and result of reoperations were collected and reviewed.A total of 58 patients underwent reoperation for hyperparathyroidism.Eleven of these patients were referred to this institute for reoperation after missing single parathyroid lesion in the initial parathyroidectomy.Nine patients were female,and the mean patient age at reoperation was 54.9 years.Results For this group,the accuracy of ultrasound neck scan and sestamibi scintigraphy was 10/11 in identifying diseased parathyroid gland before reoperation.Combined with enhanced CT and SPECT,all parathyroid lesions were localized before reoperations.With general anesthesia or cervical plexus block,all diseased parathyroid glands were removed in the reoperations.No signs of hyperparathyroidism appeared during follow-up.Conclusions The initial surgery for primary hyperparathyroidism should be performed in experienced center to avoid reoperations.Combining preoperative localization and cervical exploration will help to increase the success rate of reoperation.
