Background: Despite adequate hormone substitution in Hashimoto disease, some patients may have persistent symptoms with a possible autoimmune pathophysiology. A recent randomized trial (RCT) using patient-reported outcome measures as the primary endpoint showed benefit in total thyroidectomy, but at a cost of high complication rates.
Objective: To verify results from the RCT in an observational study including a wider range of patients and explore means of predicting who may benefit from such surgery.
