Reoperative Thyroid Procedures: Do They Pose a Higher Risk of Complications Compared to First-Time Surgery?

Area of Science:

• Endocrinology
• Surgical Oncology
• Thyroid Surgery

Background:

• Outcomes of reoperative thyroid procedures are not well-documented.
• The Collaborative Endocrine Surgery Quality Improvement Program (CESQIP) database was used to evaluate reoperative thyroid surgery outcomes.
• This study aims to compare outcomes of first-time versus reoperative thyroid procedures.

Purpose of the Study:

• To evaluate and compare the outcomes and complications of reoperative versus first-time thyroid surgery.
• To analyze complication rates, including hematoma, vocal cord dysfunction, and hypoparathyroidism.
• To assess the safety and efficacy of reoperative thyroid procedures.

Main Methods:

• Utilized the CESQIP database (2013-2023) to identify patients undergoing thyroidectomy or related procedures.
• Compared outcomes between first-time total thyroidectomy with central neck dissection and reoperative central neck surgery.
• Analyzed outcomes of first-time versus reoperative lateral neck dissection for thyroid cancer.

Main Results:

• Compared 3617 first-time and 1644 reoperative central neck surgeries; no difference in hematoma or vocal cord dysfunction.
• First-time total thyroidectomy with central neck dissection had significantly higher rates of short- and long-term hypoparathyroidism (9% vs 2% and 4% vs 2%, respectively).
• In lateral neck dissections (533 first-time, 107 reoperative), complication rates were similar between groups.

Conclusions:

• Reoperative thyroid surgery at high-volume centers offers outcomes comparable to first-time procedures.
• Total thyroidectomy with central neck dissection carries a higher risk of hypoparathyroidism compared to reoperative central neck surgery.
• Reoperative thyroid surgery is a safe and effective option, with specific risks to consider.
