Comparing the Establishment of Operation Space Between High Position and Low Position in Endoscopic Thyroid Surgery

Study Overview
=================
Brief Summary
-----------------
Patients in our department endoscopic thyroidectomy were randomly divided into high position and low position established operating space group established operating space group. The thyroid size, patient BMI, operation time, and intraoperative blood loss were compared between the two groups.

Detailed Description
-----------------
Patients in our department endoscopic thyroidectomy were randomly divided into high position and low position established operating space group established operating space group.The sternum angle level is used as the dividing line between the two groups。The thyroid size, patient BMI, operation time, and intraoperative blood loss were compared between the two groups.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: high position space group<br>The left and right Trocar meet at the level of the sternum angle and begin to establish the operating space. | Procedure: high position space group<br>* The left and right Trocar meet at the level of the sternum angle and begin to establish the operating space.<br>|
| Experimental: low position space group<br>The left and right Trocar meet under the sternum angle and begin to establish the operating space. | Procedure: low position space group<br>* The left and right Trocar meet under the sternum angle and begin to establish the operating space.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Intercostal arterial bleeding | The number of intercostal artery bleeding | During surgery | 
| Thyroidectomy time | Time to complete removal of thyroid gland specimens starting from the establishment of the operating space (minutes) | During surgery | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Thyroid volume | Thyroid volume calculated by preoperative ultrasound | Before surgery | 
| Patient's BMI | BMI equals body weight divided by height squared | Before surgery | 
| Assessment of skin sensory abnormalities | According to the visual scoring method, it was divided into 1-10 points and evaluated by the patient two months after surgery. The score of 10 points was the same as before surgery, and 0 points showed serious discomfort. | two months after surgery |
