# Comparison of the application value of bipolar electrocoagulation and ultrasonic scalpel in robot-assisted thyroid carcinoma surgery: a single-center study based on perioperative indicator and short-term prognosis

## TL;DR

This study compares two surgical tools in robot-assisted thyroid cancer surgery, finding one reduces operation time and better preserves parathyroid function.

## Contribution

The study provides new clinical evidence comparing bipolar electrocoagulation and ultrasonic scalpel in robotic thyroid surgery.

## Key findings

- Bipolar electrocoagulation reduced operation time compared to ultrasonic scalpel.
- Bipolar electrocoagulation resulted in higher drainage volume and better parathyroid function preservation.
- Postoperative PTH and serum calcium levels were higher in the bipolar electrocoagulation group.

## Abstract

To study the effectiveness of bipolar electrocoagulation cutting technology and traditional ultrasonic scalpel cutting technology in Da Vinci robot-assisted thyroid carcinoma surgery.

We retrospectively reviewed 154 patients with thyroid carcinoma who had undergone ultrasonic scalper (US, n = 81) or Maryland bipolar electrocoagulation (MB, n = 73) cutting in Da Vinci robotic surgery. The operation time, complications, efficacy and other clinical indicators were compared between the two groups.

The operation time of the MB group was significantly reduced (p < 0.05), and the drainage volume was significantly higher than that of the US group (p < 0.05). The postoperative PTH and serum calcium levels of total thyroidectomy in the MB group were higher than those in the US group (p < 0.05), which were (US: 2.07 ± 1.51, MB: 2.42 ± 1.46) and (US: 2.15 ± 0.14, MB: 2.20 ± 0.13).

Bipolar coagulation cutting technology is more precise. Its application in robotic thyroid surgery can significantly shorten the operation time and protect parathyroid function, which has better clinical application prospects.
