Completion thyroidectomy: A safe option for high-volume surgeons

Background: The risk of complication in patients undergoing completion thyroidectomy (cT) is mixed. Several studies report increased risk in comparison to total thyroidectomy (TT) and still others reporting a comparatively decreased risk. We compared the rates of complication in patients at our institution undergoing thyroid lobectomy (TL), (TT), and cT by a single high-volume surgeon.Methods: We performed a single-institution retrospective cohort study. Patients undergoing TL, TT, or cT by a high-volume surgeon were included. Rates of complication were collected and compared between the three cohorts.Results: A total of 310 patients were included. The overall rate of complication was 4.2%. The complication rates in the TL, TT, and cT cohorts were 1%, 7.1%, and 4.5%, respectively (p = 0.10). Transient hypocalcemia was slightly more common in the TT cohort (6.1%) as opposed to the TL (0%) or cT (0.9%) cohort (p = 0.01). The cohorts also had similar rates of recurrent laryngeal nerve signal loss leading to transient dysphonia (TL: 0% vs. TT: 1% vs. cT: 3.6%, p = 0.10).Conclusions: While rates of complication tended to predictably decrease as approaches became less extensive, there were no significant differences in complication rates among the three surgical approaches when performed by a high-volume surgeon. Considering the low rates of complication overall, patient counseling and preference should be emphasized to provide appropriate and tailored treatment plans.

Automated summary

This study compared the rates of complication in patients undergoing thyroid lobectomy, total thyroidectomy, and completion thyroidectomy. It was found that there were no significant differences in complication rates among the three surgical approaches when performed by a high-volume surgeon.
