Application of Non-Ligation Technique in Thyroidectomy

This study aimed to analyze the difference between non-ligation and traditional ligation techniques for papillary thyroid micro-carcinoma (PTMC) patients.

Patients undergoing thyroidectomy in the Department of General Surgery, Ruijin Hospital, affiliated with Shanghai Jiao Tong University, Lu Wan Branch, were retrospectively enrolled. The gender, age, operation method, operation duration, tumor size, size of thyroidectomy specimen, postoperative bleeding, drainage volume on the first postoperative day, preoperative and postoperative levels of parathyroid hormone (PTH), and blood calcium were collected.

Compared with the traditional ligation technique, the non-ligation technique significantly shortened the operation time (69.36 ± 1.38 vs. 82.72 ± 2.12, P < .0001) and reached less variation of the serum calcium (2.32 ± 0.01 vs 2.28 ± 0.01, P < .001) and PTH (26.58 ± 0.08 vs 22.01 ± 1.04, P < .05) on the first postoperative day, and the above biochemical indicators returned to normal 3 weeks after surgery. The PTH in the No-ligation technique group was 7.20± 1.99, which was significantly lower than that in the Traditional ligation group (20.78± 3.78) (P < .01).

No-ligation technique can significantly reduce the operation time in thyroidectomy but may temporarily affect the levels of parathyroid hormone and blood calcium, and the above changes returned to normal 3 weeks after surgery. These results highlighted that No-ligation technique can benefit patients and will be a favorable treatment method.
