[Analysis of risk factors for bleeding after thyroid surgery]

Area of Science:

• Endocrinology
• Surgical Oncology
• Anatomy

Background:

• Postoperative bleeding is a significant complication following thyroid surgery.
• Understanding risk factors and bleeding sources is crucial for patient safety.

Purpose of the Study:

• To identify risk factors associated with postoperative bleeding after thyroid surgery.
• To explore the relationship between the timing of bleeding and its anatomical sources.

Main Methods:

• Retrospective analysis of 2568 patients who underwent thyroid operations.
• Cox regression analysis was used to identify risk factors for postoperative bleeding.

Main Results:

• Forty patients (1.56%) experienced postoperative bleeding.
• Identified risk factors included extent of resection (P=0.0435) and surgeon (P=0.0071).
• Common bleeding sources within 24 hours were the thyroid bed, strap muscles/sternocleidomastoid, and wound errhysis, varying by time interval.

Conclusions:

• Extent of resection and surgeon experience are significant risk factors for postoperative bleeding after thyroid surgery.
• The thyroid bed and surrounding musculature are primary sources of bleeding within 24 hours post-operation.
