[Analysis of chyle leakage after central lymph node dissection for thyroid carcinoma]

Area of Science:

• Endocrinology
• Surgical Oncology
• Clinical Medicine

Background:

• Thyroid cancer treatment often involves central lymph node dissection.
• Chyle leakage is a potential complication following this procedure.
• Understanding its characteristics is crucial for patient management.

Purpose of the Study:

• To analyze the clinical features, treatment strategies, and prognosis of chyle leakage after thyroid cancer central lymph node dissection.
• To compare outcomes between patients with and without chyle leakage.
• To evaluate conservative management efficacy.

Main Methods:

• Retrospective analysis of 985 patients undergoing thyroid cancer surgery with central lymph node dissection.
• Categorization into groups with (n=12) and without (n=973) chyle leakage.
• Conservative treatment (fat-free diet, negative pressure drainage) applied to affected patients.

Main Results:

• The incidence of chyle leakage was 1.2%.
• Patients with chyle leakage had significantly higher postoperative drainage volumes and longer hospital stays.
• All cases resolved with conservative management, without requiring reoperation.

Conclusions:

• Chyle leakage is an uncommon complication of thyroid cancer surgery.
• Conservative management, including dietary changes and drainage, is effective for resolution.
• Secondary surgical intervention is generally not necessary.
