El abordaje transaxilar de tiroidectomía endoscópica sin gas (GETTA) es un método quirúrgico novedoso que aborda la creciente incidencia de microcarcinoma papilar de tiroides (PTMC) al tiempo que produce resultados estéticamente agradables 14,15,16. Sin embargo, esta técnica requiere una comprensión profunda de los pasos operativos clave17. Antes de comenzar la cirugía propiamente dicha, se espera...

El reciente aumento de la incidencia de microcarcinoma papilar de tiroides (CMPT)1,2, que afecta predominantemente a mujeres jóvenes, requiere avances en las técnicas quirúrgicas que ofrezcan tanto eficacia médica como sensibilidad estética 3,4. El objetivo principal del abordaje transaxilar de tiroidectomía endoscópica sin gas (GETTA), introducido por Chung en 20045, es proporcionar un método quirúrgico óptimo que combine estas dos necesidades.
GETTA se desarrolló como respuesta a los inconvenientes de la cirugía abierta tradicional, como las cicatrices notables que conducen a la timidez de los pacientes y el posible impacto negativo en sus actividades laborales y sociales. La cirugía tiroidea endoscópica se ha ido aplicando paulatinamente en el tratamiento de las enfermedades tiroideas benignas y malignas 3,4, ofreciendo una alternativa menos invasiva a la cirugía abierta. Sin embargo, la innovación de GETTA radica en su enfoque único sin gas. El procedimiento GETTA tiene varias ventajas sobre las técnicas alternativas. Establece la cavidad a través de los pliegues naturales de la axila, ocultando la incisión y produciendo resultados cosméticos postoperatorios superiores6. Además, GETTA omite la necesidad de inflar el gasCO2 durante la operación, evitando así complicaciones relacionadas con el gas CO2. Además, este abordaje deja intacto el colgajo anterior del cuello, lo que protege la función de la región cervical anterior después de la cirugía y evita la deglución postoperatoria de la unión piel-traqueal 6,7.
La técnica se sitúa dentro del cuerpo más amplio de la literatura sobre cirugía endoscópica de tiroides. Si bien existen amplios informes de investigación sobre el abordaje transoral y mamario de la cirugía tiroidea endoscópica 8,9, la cirugía tiroidea no inflable sigue siendo poco reportada10,11. En consecuencia, este método constituye una contribución significativa a este campo, proporcionando un protocolo completo para el procedimiento GETTA.
Para los lectores que contemplan la aplicación de este método, es más adecuado para pacientes con carcinoma papilar de tiroides en etapa temprana y de bajo riesgo que desean cicatrices mínimas después de la cirugía. Sin embargo, el éxito de esta técnica depende de la competencia del profesional en los procedimientos endoscópicos debido a sus limitaciones espaciales. Como tal, el método puede no ser apropiado para profesionales sin habilidades endoscópicas avanzadas o aquellos en centros médicos con acceso limitado al equipo necesario.
Este artículo tiene como objetivo reforzar la comprensión del procedimiento GETTA, ofreciendo información sobre su aplicación y, con suerte, promoviendo su adopción en más centros médicos. Los beneficios de GETTA se extienden más allá de la eficacia médica, satisfaciendo el deseo de los pacientes de una cirugía menos invasiva con resultados cosméticos favorables.

gasless endoscopic thyroidectomy via the trans-axillary approach

Para los pacientes con carcinoma papilar de tiroides temprano y de bajo riesgo, un número cada vez mayor opta por la cirugía endoscópica de tiroides debido a su capacidad para lograr resultados terapéuticos favorables mientras mantiene excelentes resultados cosméticos. Entre los procedimientos endoscópicos disponibles, el abordaje transaxilar de tiroidectomía endoscópica sin gas (GETTA) ha ganado popularidad entre los cirujanos. Esto se atribuye a su sencilla construcción de cavidad, su amplia área de operación, su exposición precisa al campo visual y su curva de aprendizaje manejable. Sin embargo, pocos estudios han proporcionado descripciones detalladas de los pasos quirúrgicos específicos involucrados en GETTA. A partir de una síntesis de la literatura existente y de nuestra propia experiencia clínica, presentamos un esquema completo del procedimiento GETTA. Este proceso se puede clasificar en cinco etapas distintas: posicionamiento y planificación de la incisión; establecimiento de cavidades quirúrgicas; identificación y protección del nervio laríngeo recurrente, la glándula paratiroides inferior y la disección central del cuello; localización y preservación del nervio laríngeo superior, la glándula paratiroides superior y la disección del polo superior de la tiroides; transección del istmo tiroideo seguida de resección en bloque de la glándula tiroides y los ganglios linfáticos centrales del cuello. El enfoque de cinco pasos de GETTA es fácil de aprender y se puede adaptar para resecar enfermedades tiroideas y paratiroideas benignas y malignas.

En este estudio, una cohorte de 200 pacientes del sexo femenino, todas con una edad media de 36 años (DE = 4,52; rango de 20 a 59 años), se sometió al abordaje transaxilar de tiroidectomía endoscópica sin gas (GETTA) (Tabla 1). Los pacientes presentaron un Índice de Masa Corporal (IMC) promedio de 22,79 kg/m2 (DE = 4,52; rango = 18,27-27,31). La ecografía indicó un tamaño tumoral promedio de 7,09 mm (DE = 3,84). Todos los pacientes fueron plenamente informados de las opciones quirúrg...

Gasless Endoscopic Thyroidectomy via the Trans-Axillary Approach

Este protocolo presenta el procedimiento para la realización de tiroidectomía mediante el abordaje transaxilar de tiroidectomía endoscópica sin gas (GETTA).

Tiroidectomía endoscópica sin gas por vía transaxilar

For patients with early, low-risk papillary thyroid carcinoma, an increasing number are opting for endoscopic thyroid surgery due to its ability to ...

El enfoque de cinco pasos de GETTA es fácil de aprender y se puede adaptar para diseccionar enfermedades tiroideas y paratiroideas benignas y malignas. Esta técnica ofrece resultados cosméticos significativamente mejorados. Elimina la insuflación de gas de dióxido de carbono y preserva la función de la región cervical anterior.Es una técnica viable y segura para pacientes con carcinoma papilar de tiroides precoz de bajo riesgo que desean evitar una cicatriz cervical. Para comenzar, coloque al paciente anestesiado en posición supina y abduca la extremidad superior del lado afectado en un ángulo de 60 a 90 grados. Luego, haga una incisión primaria de aproximadamente cuatro a seis centímetros de largo con un bisturí.A continuación, haz una incisión secundaria de unos 0,5 centímetros con un bisturí quirúrgico para el trócar. Localiza el espacio entre la cabeza esternal del músculo cleo mastoideo esternal y la cabeza de la clavícula. Con el mini botón del bisturí ultrasónico, coagule los pequeños vasos sanguíneos dentro del espacio.Emplee pinzas de disección en el bisturí ultrasónico para diseccionar el espacio anatómico entre el músculo esternotiroideo y la vena yugular interna. Disecciona el espacio natural entre el músculo tiroideo y el esternotiroides. Coloque los retractores dentro del espacio y complete la creación de las cavidades quirúrgicas.Localice el nervio laríngeo recurrente alrededor de la bifurcación de la arteria tiroidea inferior con una sonda de monitoreo nervioso. Diseccionar el área alrededor de la arteria tiroidea inferior mientras se protegen y coagulan los vasos sanguíneos de la tiroides inferior para exponer la tráquea. Después de coagular y cortar las ramas de la arteria tiroidea inferior, siga la vía nerviosa hasta la laringe, asegurando su protección durante el proceso de disección.Realizar un método de disección central del cuello, como una cirugía abierta, y extirpar los ganglios linfáticos del compartimento central del cuello en función de la extensión de la enfermedad del paciente. Después de separar el polo superior de la glándula tiroides, continúe el proceso de separación a lo largo del espacio cricotiroideo para exponer los vasos sanguíneos del polo tiroideo superior. Con el mini botón del bisturí ultrasónico, coagule y corte con cuidado los vasos sanguíneos del polo superior de la glándula tiroides.Disociar completamente el espacio entre el polo superior de la glándula tiroides y el músculo cricotiroides. Utilice un bisturí ultrasónico para coagular los vasos sanguíneos pequeños. A continuación, extirpa tanto el istmo tiroideo como los ganglios linfáticos situados en la zona central junto a la glándula tiroides.Recoja el espécimen en la bolsa de especímenes. Con un aspirador laparoscópico, enjuague la cavidad quirúrgica con solución salina estéril tibia. Luego, coloque un tubo de drenaje cerca de la tráquea y use pinzas de disección para guiar el tubo fuera de la axila.Cierre la incisión axilar con una sutura 4.0 reabsorbible interrumpida de 30 centímetros. En este estudio, una cohorte de 200 pacientes femeninas con una edad media de 36 años se sometió a la tiroidectomía endoscópica sin gases por abordaje transaxilar. Cinco pacientes experimentaron un debilitamiento temporal recurrente de la señal nerviosa laríngea, después de la cirugía, que se resolvió después de un mes.No se observaron casos de lesiones recurrentes permanentes del nervio laríngeo. Sin embargo, tres pacientes requirieron conversión a cirugía abierta debido a hemorragia intraoperatoria. Es crucial reconocer y proteger el nervio laríngeo recurrente antes de cualquier intervención quirúrgica que implique coagulación o corte.Después de este procedimiento, la paratiroidectomía y la disección de los ganglios linfáticos laterales se pueden realizar simultáneamente con un procedimiento. Con un mayor refinamiento, esta técnica puede facilitar la tiroidectomía total, la paratiroidectomía y las disecciones de los ganglios linfáticos laterales, además de ser adaptable para cirugías endoscópicas de mama.

Gasless Endoscopic Thyroidectomy via the Trans-Axillary Approach

Permanent Cerebral Vessel Occlusion via Double Ligature and Transection

Stroke is a leading cause of death, disability, and socioeconomic loss worldwide. The majority of all strokes result from an interruption in blood flow (ischemia) 1. Middle cerebral artery (MCA) delivers a great majority of blood to the lateral surface of the cortex 2, is the most common site of human stroke 3, and ischemia within its territory can result in extensive dysfunction or death 1,4,5. Survivors of ischemic stroke often suffer loss or disruption of motor capabilities, sensory deficits, and infarct. In an effort to capture these key characteristics of stroke, and thereby develop effective treatment, a great deal of emphasis is placed upon animal models of ischemia in MCA.
Here we present a method of permanently occluding a cortical surface blood vessel. We will present this method using an example of a relevant vessel occlusion that models the most common type, location, and outcome of human stroke, permanent middle cerebral artery occlusion (pMCAO). In this model, we surgically expose MCA in the adult rat and subsequently occlude via double ligature and transection of the vessel. This pMCAO blocks the proximal cortical branch of MCA, causing ischemia in all of MCA cortical territory, a large portion of the cortex. This method of occlusion can also be used to occlude more distal portions of cortical vessels in order to achieve more focal ischemia targeting a smaller region of cortex. The primary disadvantages of pMCAO are that the surgical procedure is somewhat invasive as a small craniotomy is required to access MCA, though this results in minimal tissue damage. The primary advantages of this model, however, are: the site of occlusion is well defined, the degree of blood flow reduction is consistent, functional and neurological impairment occurs rapidly, infarct size is consistent, and the high rate of survival allows for long-term chronic assessment.

Permanent Cerebral Vessel Occlusion via Double Ligature and Transection

We describe a highly reproducible method for the permanent occlusion of a rodent major cerebral blood vessel. This technique can be accomplished with very little peripheral damage, minimal blood loss, a high rate of long-term survival, and consistent infarct volume commensurate with the human clinical population.

Non-invasive Assessment of the Efficacy of New Therapeutics for Intestinal Pathologies Using Serial Endoscopic Imaging of Live Mice

Animal models of inflammatory bowel disease (IBD) and colorectal cancer (CRC) have provided significant insight into the cell intrinsic and extrinsic mechanisms that contribute to the onset and progression of intestinal diseases. The identification of new molecules that promote these pathologies has led to a flurry of activity focused on the development of potential new therapies to inhibit their function. As a result, various pre-clinical mouse models with an intact immune system and stromal microenvironment are now heavily used. Here we describe three experimental protocols to test the efficacy of new therapeutics in pre-clinical models of (1) acute mucosal damage, (2) chronic colitis and/or colitis-associated colon cancer, and (3) sporadic colorectal cancer. We also outline procedures for serial endoscopic examination that can be used to document the therapeutic response of an individual tumor and to monitor the health of individual mice. These protocols provide complementary experimental platforms to test the effectiveness of therapeutic compounds shown to be well tolerated by mice.

We describe methods for longitudinal monitoring of the efficacy of therapeutics for the treatment of colonic pathologies in mice using a rigid endoscope. This protocol can be readily used for the characterization of the therapeutic response of an individual tumor in live mice and also for monitoring potential disease relapse.

Step-by-Step Stapedotomy through Transcanal Exclusive Endoscopic Approach

In recent years there has been an increasing trend in the use of the endoscope to treat a variety of middle ear pathologies, including otosclerosis. Several studies comparing traditional microscopic and endoscopic stapes surgery have reported similar hearing results and an overall low rate of complications. The endoscope has unraveled its full potential in demanding settings of stapes surgery, such as unfavorable anatomy of the oval window niche or revision cases. Reduced manipulation of the chorda tympani and low rate of post-operative dysgeusia are further benefits to mention for endoscopic stapes surgery.
Being a one-handed technique, management of bleeding, positioning, and crimping of the prosthesis may be challenging for novice endoscopic surgeons, so some training in endoscopic ear surgery is recommended before performing endoscopic stapedotomy. The problem of sharing the surgical field between the endoscope and the operating instruments could be easily overcome if proper instruments positioning is understood. One-handed bleeding control in the narrow space of the ear canal may represent an issue during the elevation of the tympano-meatal flap, possibly discouraging the surgeon since the preliminary steps of surgery. Following appropriate technique to raise the flap and the collaboration with the anesthesiology team in keeping the blood pressure low guarantee an adequate bleeding control in most cases.
The aim of this article is to describe the entire surgical procedure of a transcanal exclusive endoscopic stapedotomy, from operating room set up and patient positioning to post-operative care. A step-by-step description of the surgical maneuvers with technical hints is reported, to guide the surgeon across the procedure and allow any ear surgeon to perform stapes surgery endoscopically.

The aim of this article is to provide a step-by-step method for endoscopic stapes surgery from operating room setting and patient positioning to post-operative care. This work would represent a guide for any otologic surgeon who is willing to treat otosclerosis with endoscopic transcanal technique.

Endoscopic Cholesteatoma Surgery

Implementation of endoscopes in cholesteatoma surgery resulted in considerable changes in the management of cholesteatoma in the last two decades. Compared to the microscopic approach with an excellent but straight-line view and limited illumination, the introduction of endoscopes provides a wide-angled panoramic view. Moreover, angled lenses allow the surgeon to visualize the middle ear and its hidden recesses through a transcanal, minimally-invasive approach. The endoscope enables the surgeon to remove limited cholesteatoma of the middle ear and its recesses using an exclusive endoscopic technique by taking advantage of these benefits. This reduces the rate of residual disease and sparing external incisions and excessive temporal bone drilling as in a transmastoid approach. Since transcanal endoscopic access is mainly a one-handed technique, it implies the need for specific procedures and technical refinements. This article describes a step-by-step guide as a surgical manual for endoscopic removal of epitympanic cholesteatoma. Different techniques for cholesteatoma dissection and bone removal for epitympanectomy, including curettage and powered instruments such as drills and ultrasonic devices with their outcomes, are discussed. This may offer ear surgeons insight into technical refinements and the latest technological developments and open the horizon for different techniques.

The present protocol describes a step-by-step guide for the complete endoscopic removal of epitympanic cholesteatoma with different techniques for cholesteatoma dissection and bone removal for epitympanectomy.

Laparoscopic Radical Antegrade Modular Pancreatosplenectomy via Dorsal-Caudal Artery Approach for Pancreatic Neck-Body Cancer

Laparoscopic radical resection of the pancreatic neck is one of the most complicated radical operations for pancreatic cancer, especially for patients who have had neoadjuvant chemotherapy. Here, we present a technique to perform laparoscopic radical antegrade modular pancreatosplenectomy (L-RAMPS) using the dorsal-caudal artery approach by making full use of the high-definition vision and operation modes of the laparoscope.
The innovation and optimization of this operation are provided in the protocol. Priority should be given to the dorsal resection plane, including the dorsal side of the superior mesenteric artery (SMA), the dorsal side of the pancreatic head, the root of the celiac artery (CeA), the ventral side of the left renal vessels, and the renal hilum. On the condition that the operation for pancreatic neck-body cancer is feasible and safe, the second step is to perform tumor resection en bloc surrounding the SMA and CeA from the caudal to the cephalic side to increase the rate of R0 (radical zero) resection and further prognosis.

Laparoscopic Radical Antegrade Modular Pancreatosplenectomy via Dorsal-Caudal Artery Approach for Pancreatic Neck-Body Cancer

With advancements in laparoscopic techniques, laparoscopic radical antegrade modular pancreatosplenectomy (L-RAMPS) has been widely recognized. However, owing to several technical difficulties in this procedure, the artery-first approach in L-RAMPS still remains uncommon. Here, we developed the dorsal-caudal artery approach for L-RAMPS, which might be safe and beneficial for pancreatic neck tumors.

Transoral Endoscopic Thyroidectomy Vestibular Approach for Thyroid Lobectomy

The manuscript describes the transoral endoscopic thyroidectomy vestibular approach (TOETVA) for thyroid lobectomy. The patient is placed in the supine position with extension and fixation of the neck. One 20 mm transverse incision and two 5 mm incisions are made through the mucosa of the oral vestibule for camera and instrument placement after disinfection of the skin and oral cavity. The workspace is established and maintained by the skin suspension device, which is made of unabsorbable string (3-0) and rubber bands, and the CO2 insufflation pressure. Lobectomy using a medial-to-lateral technique and prophylactic ipsilateral central neck dissection is performed simultaneously on patients with papillary thyroid cancer (PTC). The specimen is extracted through the 20 mm incision. The parathyroid gland is immediately searched for in the specimen and auto-transplanted to the left brachioradialis. A drainage tube is inserted through the retractor hole into the bed of the thyroid gland, and absorbable sutures are used to close the mucosal incisions in the oral vestibule and the linea alba cervicalis. Prophylactics administered intravenously are recommended for the first 24 h after surgery, and oral antibiotics are used for 7 days postoperatively.

Here, we present a protocol to describe the methodology for the transoral endoscopic thyroidectomy vestibular approach in detail.

Techniques of Endoscopic Ossiculoplasty

The utilization of endoscopes in modern otology has evolved from diagnostic purposes to the development of exclusive endoscopic ear surgery. This technique offers a panoramic view of the middle ear and provides an optimal magnification of the oval window region, the stapes' suprastructure, and the footplate, allowing great precision in prosthesis positioning during ossiculoplasty (OPL). Various techniques for ossicular chain reconstruction have been described in the literature. Either autologous or synthetic materials can be used for reconstruction. The use of a patient's own tissue minimizes the risk of implant rejection or extrusion of the prosthesis through the tympanic membrane. On the other hand, synthetic materials like titanium are light and rigid and do not require time-consuming prosthesis remodeling. The main objective of this article is to present a comprehensive step-by-step guide that serves as a surgical manual for exclusive endoscopic OPL. This guide will explain various forms of OPL using synthetic and autologous materials. The goal is to provide a comprehensive understanding of the various surgical techniques and support the integration into clinical practice.

Percutaneous Endoscopic Unilateral-Approach Bilateral Decompression for Lumbar Spinal Stenosis

Lumbar spinal stenosis (LSS) involves the narrowing of the spinal canal due to degenerative changes in the vertebral joints, intervertebral discs, and ligaments. LSS encompasses central canal stenosis (CCS), lateral recess stenosis (LRS), and intervertebral foramen stenosis (IFS). The utilization of lumbar endoscopic unilateral laminotomy for bilateral decompression (LE-ULBD) has gained popularity in the treatment of CCS and LRS. This popularity is attributed to the rapid development of endoscopic instruments and the progress of endoscopic philosophy.
In this technical report, a detailed introduction to the steps and key points of LE-ULBD is provided. Simultaneously, a retrospective review of 132 consecutive patients who underwent LE-ULBD for central canal and/or lateral recess stenosis was conducted. The outcomes after more than two years of follow-up were assessed using the visual analogue score (VAS), Oswestry Disability Index (ODI), Japanese Orthopaedic Association (JOA) scores, and the modified MacNab criteria to evaluate surgical efficacy. All 132 patients underwent LE-ULBD successfully. Among them, 119 patients were rated as "excellent," while 13 patients were rated as "good" based on the modified MacNab criteria during the last follow-up. Incidental dural tears occurred in four cases, but there were no post-operative epidural hematomas or infections. The experience demonstrates that LE-ULBD is a less invasive, effective, and safe approach. It can be considered as an alternative option for treating patients with lumbar central canal stenosis and/or lateral recess stenosis.
