Objective: Systematic review of thyroid surgeries, at John Hopkins Aramco Healthcare between 2016 and 2019, including histopathology, epidemiology and surgical outcomes in order to improve practice and build efficient protocol.

Materials and methods: Retrospective cohort study of all thyroidectomy cases including total thyroidectomy, hemithyroidectomy and completion thyroidectomy for different indications from January 2016 till December 2019. 

Results: Majority of our papulation study were female patients representing 71.3%, while male patient represented only 28.2%.  65.6% of patients were found to have benign lesions while 34.4% patients had malignant lesions, papillary thyroid carcinoma, PTC was found to be the commonest malignant pathology in our patients, followed by follicular thyroid carcinoma, then MALT, medullary carcinoma were found to be the least common. In total surgical complications ratio were few, majority of them were female which is related to high gender affection 81.2%, patients who had temporary hypocalcemia represent 9.1%. Patients who had permanent hypocalcemia were found to be 2.9%. While patients who had hematoma as a complication were 1.1%. patients who had temporary RLN injury were 1.4% patients. Patients who had permanent RLN injury were 0.36%.

Conclusion: After reviewing our data and results, thyroidectomy was a safe and efficient surgical procedure, our results were similar to international standards.  Auditing and reporting of thyroidectomy surgery outcomes in all national centers can help to establish local guidelines which will boost patient care.
