Complications of completion versus total thyroidectomy

Area of Science:

• Endocrinology
• Surgical Oncology
• Thyroid Surgery

Background:

• Thyroidectomy is a common procedure for benign and malignant thyroid diseases.
• Completion thyroidectomy is performed after initial surgery for thyroid cancer.
• Complication rates vary between primary and completion thyroidectomy procedures.

Purpose of the Study:

• To analyze complication rates after completion thyroidectomy.
• To compare these rates with primary total thyroidectomy for differentiated thyroid cancer (DTC) and benign diseases.

Main Methods:

• Retrospective analysis of 647 patients undergoing thyroidectomy.
• Group 1: 159 patients (completion thyroidectomy for DTC).
• Group 2: 217 patients (total thyroidectomy for DTC).
• Group 3: 271 patients (total thyroidectomy for benign diseases).

Main Results:

• No significant difference in complications between completion and primary total thyroidectomy for DTC, except for temporary hypocalcemia.
• No significant difference between total thyroidectomies for DTC and benign diseases, except for unilateral temporary recurrent laryngeal nerve (RLN) palsy.

Conclusions:

• Surgical techniques have reduced thyroidectomy complication rates.
• Temporary RLN palsy and hypoparathyroidism remain significant concerns in completion thyroidectomies.
• Careful preoperative evaluation and adequate surgical technique are essential for minimizing complications.
