Gasless Endoscopic Thyroidectomy via the Trans-Axillary Approach

Summary

This protocol presents the procedure for conducting thyroidectomy using the gasless endoscopic thyroidectomy trans-axillary approach (GETTA).

Abstract

For patients with early, low-risk papillary thyroid carcinoma, an increasing number are opting for endoscopic thyroid surgery due to its ability to achieve favorable therapeutic outcomes while maintaining excellent cosmetic results. Among the available endoscopic procedures, the Gasless Endoscopic Thyroidectomy Trans-axillary Approach (GETTA) has gained popularity among surgeons. This is attributed to its straightforward cavity construction, spacious operating area, precise visual field exposure, and manageable learning curve. However, few studies have provided detailed descriptions of the specific surgical steps involved in GETTA. Drawing from a synthesis of existing literature and our own clinical expertise, we present a comprehensive outline of the GETTA procedure. This process can be categorized into five distinct stages: positioning and incision planning; establishment of surgical cavities; identification and protection of the recurrent laryngeal nerve, inferior parathyroid gland, and central neck dissection; localization and preservation of the superior laryngeal nerve, superior parathyroid gland, and dissection of the thyroid's superior pole; transection of the thyroid isthmus followed by en bloc resection of the thyroid gland and central neck lymph nodes. The five-step approach of GETTA is easy to learn and can be adapted for resecting both benign and malignant thyroid and parathyroid diseases.

Introduction

The recent increase in the incidence of papillary thyroid microcarcinoma (PTMC)^1,2, predominantly affecting young women, necessitates advancements in surgical techniques that offer both medical effectiveness and aesthetic sensitivity^3,4. The primary goal of the Gasless Endoscopic Thyroidectomy Trans-axillary Approach (GETTA), introduced by Chung in 2004⁵, is to provide an optimal surgical method that marries these two needs.

GETTA was developed as an answer to the drawbacks of traditional open surgery....

Protocol

This study was conducted in strict accordance with the ethical principles outlined in the Declaration of Helsinki and adhered to the guidelines established by our institution's Human Research Ethics Committee. The research protocol underwent a thorough review and received approval from the Ethics Committee of West China Hospital of Sichuan University. All participating patients provided written informed consent before their involvement in the study, and stringent measures were taken to ensure the privacy and confiden.......

Discussion

The Gasless Endoscopic Thyroidectomy Trans-axillary Approach (GETTA) is a novel surgical method that addresses the rising incidence of Papillary Thyroid Microcarcinoma (PTMC) while yielding aesthetically pleasing outcomes^14,15,16. Nevertheless, this technique requires a deep understanding of key operational steps¹⁷. Before commencing the actual surgery, surgeons are expected to familiarize themselves with.......
