Endoscopic Combined Intrarenal Surgery: best practices and future perspectives.

INTRODUCTION: Endoscopic Combined Intrarenal Surgery (ECIRS) has emerged as a promising technique for the management of large and complex kidney stones, potentially offering advantages over traditional Percutaneous Nephrolithotomy (PCNL). This study aims to evaluate best practices, outcomes, and future perspectives associated with ECIRS. MATERIALS AND METHODS: A comprehensive PubMed search was conducted from 2008 to 2024, using MESH terms and the following key words: "ECIRS" and "Endoscopic Combined Intrarenal Surgery" The search yielded 157 articles, including retrospective cohort studies, two randomized controlled trials (RCTs), and four meta-analyses comparing ECIRS with PCNL. Most important findings were summarized regarding indications, patient positioning, kidney access, tract size, surgical outcomes, and complications. RESULTS: ECIRS demonstrated higher stone-free rate, lower complication rate, and a reduced need for multiple procedures compared to traditional PCNL. Additionally, ECIRS has the potential to integrate new technologies to further enhance outcomes. CONCLUSION: ECIRS demonstrates significant advantages in the management of large kidney stones. Future research should focus on well-designed RCTs to provide robust evidence of its efficacy, safety, and cost-effectiveness, potentially establishing ECIRS as the first option treatment for complex kidney stones.

Intraoperative changes of surgical approach and a second surgery after percutaneous endoscopic surgery for lumbar spinal stenosis.

OBJECTIVE: To investigate the reasons for a second surgery after Percutaneous Endoscopic Surgery (PES) for lumbar spinal stenosis and to provide references for the choice of indications and appropriate surgical approach. METHOD: A total of 426 patients received PES for lumbar spinal stenosis. The postoperative, intraoperative, and postoperative data of the subjects were analyzed. The reasons for intraoperative difficulties, poor outcomes after surgery, and a second surgery were analyzed. RESULT: The surgical approach was changed in four out of 426 patients (0.94 %) during surgery, and 6 patients (1.4 %) received a second surgery; 3 out of 4 patients were intraoperatively shifted to PIED using the Delta endoscope, and 1 shifted to ordinary PIED. The reasons for the intraoperative change of surgical approach included severe hyperplasia and obscure anatomic structure in 3 patients and a dural sac tear with neural outflow in 1 patient. The reasons for a second surgery in 19 patients were as follows: nerve entrapment by bone fragments in 1 patient; nerve injury in 3 patients; lumbar instability in 3 patients; untreated or residual Lumbar Intervertebral Disc Herniation (LIDH) in 4 patients; recurrent LIDH in 1 patient; and inadequate decompression in 7 patients. CONCLUSION: Severe hyperplasia, obscure anatomic structure, lumbar instability, and nerve injury are the common reasons for a second surgery after PES for lumbar spinal stenosis. Appropriate indications and surgical approaches can be chosen based on the patient's situations and technical conditions.

Noninvasive intracranial pressure profile in 31 patients submitted to fullendoscopic spine surgery.

PURPOSE: Full-endoscopic spine surgery (FESS) is associated with specific complications, possibly linked to increased intracranial pressure (ICP) resulting from continuous saline infusion into the epidural space. This study aimed to assess the impact of saline irrigation and its correlation with noninvasively obtained ICP waveform changes. METHODS: Patients undergoing FESS between January 2019 and November 2020 were included. Noninvasive ICP (n-ICP) monitoring utilized an extracranial strain sensor generating ICP waveforms, from which parameters P2/P1 ratio and time to peak (TTP) values were derived and correlated to irrigation and vital parameters. Documentation occurred at specific surgical intervals (M0-preoperatively; M1 to M4-intraoperatively; M5-postoperatively). Mixed-model analysis of variance and multiple comparisons tests were applied, with M0 as the baseline. RESULTS: Among 31 enrolled patients, three experienced headaches unrelated to increased ICP at M5. The P2/P1 ratio and TTP decreased during surgery (p < 0.001 and p < 0.004, respectively). Compared to baseline, P2/P1 ratio and vital parameters remained significantly lower at M5. No significant differences were observed for fluid parameters throughout surgery. CONCLUSIONS: This study demonstrated a decline in the n-ICP parameters after anesthetic induction despite the anticipated increase in ICP due to constant epidural irrigation. The n-ICP parameters behaved independently of fluid parameters, suggesting a potential protective effect of anesthesia.

Endoscopic Calcaneoplasty in Haglund Disease: Surgical Technique, Clinical and Subjective Outcomes.

BACKGROUND: During the last decade, arthroscopic procedures have been replacing open techniques in Haglund disease treatment because of their considerable advantages. Endoscopic calcaneoplasty is a technique that allows resection of posterosuperior calcaneal exostosis and retrocalcaneal bursitis. The objective of this article was to describe this technique and report its clinical and subjective outcome. METHODS: A retrospective study was performed of consecutive patients undergoing endoscopic Haglund resection surgery between July 2014 and March 2020 at a single academic institution. All patients were surveyed in person about the level of pain (visual analog scale), its location (central, lateral, medial or diffuse), its relation with rest, or physical activity. Clinical evaluation was assessed using the hindfoot scale designed by the American Orthopaedic Foot & Ankle Society (AOFAS). RESULTS: In this study, 14 endoscopic calcaneoplasties were performed in 14 patients, with an average follow-up of 40 months. The visual analog scale score improved from a preoperative average value of 9.07 to 1.8 after surgery (P > .0001). The AOFAS scale rose from 38.7 before surgery to 94.6 postoperative (P > .0001). Good subjective results were observed in 12 patients (85.7%), and all of them would have surgery again. There were no wound complications or infections. No patient required reoperation. CONCLUSION: In this relatively small cohort, we found that endoscopic calcaneoplasty was associated with good clinical and subjective results with few complications.

New ipsilateral full endoscopic interlaminar approach for L5-S1 foraminal and extraforaminal decompression: technique description and initial case series.

BACKGROUND: The L5-S1 interlaminar access described in 2006 by Ruetten et al. represented a paradigm shift and a new perspective on endoscopic spinal approaches. Since then, the spinal community has shown that both the traditional ipsilateral and novel contralateral interlaminar approaches to the L5-S1 foramen are good alternatives to transforaminal access. This study aimed to provide a technical description and brief case series analysis of a new endoscopic foraminal and extraforaminal approach for pathologies at the lumbar L5-S1 level using a new ipsilateral interlaminar approach. METHODS: Thirty patients with degenerative stenotic conditions at the L5-S1 disc level underwent the modified interlaminar approach. The surgical time, blood loss, occurrence of complications, and clinical outcomes were recorded. The data were compiled in Excel and analyzed using R software version 4.2. All continuous variables are presented as the mean, median, minimum, and maximal ranges. For categorical variables, data are described as counts and percentages. RESULTS: Thirty patients were included in the study. The cohort showed significant improvements in all quality-of-life scores (ODI, visual analog scale of back pain, and visual analog scale of leg pain). Five cases of postoperative numbness and three cases of postoperative dysesthesia have been reported. No case of durotomy or leg weakness has been reported. CONCLUSIONS: The fundamental change proposed by this procedure, the new ipsilateral approach, presents potential advantages to surgeons by overcoming anatomical challenges at the L5-S1 level and by providing surgeon-friendly visualization and access. This approach allows for extensive foraminal and extraforaminal decompression, including the removal of hernias and osteophytosis, without causing neural retraction of the L5-S1 roots while maintaining the stability of the operated level.

Endoscopic surgery for craniosynostosis: a bibliometric analysis of primary studies.

INTRODUCTION: Bibliometrics, a statistical method assessing the influence of scholarly works, was employed to analyze the evolution of endoscopic surgery for craniosynostosis. METHODS: This comprehensive review followed PRISMA guidelines, sourcing data from PubMed, Embase, and Web of Science, focusing on clinical and surgical outcomes up to December 2023. We identified 1409 records, with 83 papers meeting inclusion criteria. RESULTS: The majority of studies originated from the Americas (79%), predominantly from the United States (75.9%). The typical study design was retrospective cohort studies (62%), involving a total of 8,175 patients with median research duration of 8 years. Citation metrics indicated an average count of 38.9 per paper, with notable contributions from several key authors. A distinct increase in research was observed in recent years, particularly from 2011 onwards, peaking in 2022 and 2023. The top 10 most cited papers, largely emanating from the U.S., had a higher median patient number (103) compared to the overall median (53), suggesting their significant impact. These papers were primarily published in journals with higher impact factors and citation indicators. The most cited research was notably published in the Journal of Neurosurgery-Pediatrics. CONCLUSION: This analysis provides a comprehensive view of the field, highlighting the growing trend and clinical importance of endoscopic approaches in craniosynostosis, offering a valuable resource for future research and clinical practice.

Shaping the curve from the microscopic transsphenoidal to the endoscopic endonasal approach for the sellar region.

OBJECTIVE: This study aimed to investigate the limitations, barriers, and complications in the early transition from the microscopic transsphenoidal approach (MTA) to the endonasal endoscopic approach (EEA) to the skull base in our institution. METHODS: Technical challenges, as well as clinical features and complications, were compared between MTA, EEA, and mixed cases during the early surgical curve. RESULTS: The period from the early learning curve was 1 year until the EEA protocol was used routinely. A total of 34 patients registered a resection using a transsphenoidal approach. Eighteen patients underwent EEA, 11 underwent MTA, and five underwent a mixed endonasal and microscopic approach. Non-significant differences were found in endocrine outcomes between the three groups. Patients with unchanged or improved visual function were higher in the EEA group (p = 0.147). Non-significant differences were found in terms of the extent of resection (EOR) between groups (p = 0.369). Only 1 (2.9%) patient in the whole series developed a post-operative CSF leaking that resolved with medical management, belonging to the EEA group (5.5%). CONCLUSIONS: The early phase of the learning curve did not affect our series significantly in terms of the EOR, endocrine status, and visual outcomes.

OBJETIVO: Investigar las limitaciones, las barreras y las complicaciones en la transición del abordaje transesfenoidal microscópico (ATM) al abordaje endonasal endoscópico (AEE) para la base del cráneo en nuestra institución. MÉTODO: Se compararon las características clínicas y las complicaciones entre ATM, AEE y casos mixtos durante la curva quirúrgica temprana. RESULTADOS: El periodo desde la curva de aprendizaje inicial fue de 1 año hasta que se utilizó el protocolo AEE de forma sistemática. Un total de 34 pacientes tuvieron una resección por vía transesfenoidal. A 18 pacientes se les realizó AEE, a 11 ATM y a 5 abordaje mixto endonasal y microscópico. Se encontraron diferencias no significativas en los resultados endocrinos entre los tres grupos. Los pacientes con función visual sin cambios o mejorada fueron más en el grupo AEE (p = 0.147). No se encontraron diferencias significativas respecto a la extensión de la resección (p = 0.369). Solo 1 (2.9%) paciente desarrolló una fístula de líquido cefalorraquídeo que se resolvió con manejo médico, perteneciente al grupo AEE (5.5%). CONCLUSIONES: La fase inicial de la curva de aprendizaje no afectó significativamente a nuestra serie en términos de extensión de la resección, estado endocrino y resultados visuales.

Novedosa técnica para retiro de proyectil de exobase de cráneo guiada por endoscopia a través de sistema de dilatadores tubulares utilizados para cirugía mínimamente invasiva de columna. A propósito de un caso / A novel technique for removal of skull exobase projectile guided by endoscopy through a system of tubular dilators used for minimally invasive spine surgery. About a case

Las heridas de arma de fuego en la región craneofacial representan una actividad con frecuencia en aumento en la actividad médica, y su gravedad depende del tipo de arma utilizada y la distancia del impacto. Entre ellas, las producidas por proyectiles de baja energía producen heridas con un perfil característico, que son una pequeña puerta de entrada con destrucción mínima de tejido inicial, generalmente sin orificio de salida por perder velocidad al contactar con estructuras óseas. El resultado de esto es que el proyectil se aloja en la profundidad del complejo craneofacial, lo cual demanda al cirujano un amplio conocimiento y manejo anatómico para su abordaje. En el presente artículo se describe una novedosa técnica para retiro de proyectil de la fosa pterigomaxilar, guiada por endoscopia a través de un sistema de dilatadores tubulares utilizados para cirugía mínimamente invasiva de columna, en un paciente masculino de 14 años. Luego del retiro del mismo, se continúa con los controles posoperatorios alejados, sin intercurrencias, asintomático e inserto en sus actividades diarias, con una cicatriz mínima, y sin atrofia de la región temporal. Los estudios por imágenes de control visualizan el correcto retiro del cuerpo extraño, con estructuras adyacentes sin lesiones a considerar

Gunshot wounds in the craniofacial region represent an increasingly frequent activity in medical activity, and its severity depends on the type of weapon used and the distance of the impact. Among them, those produced by low-energy projectiles produce wounds with a characteristic profile, which are a small entrance door with minimal initial tissue destruction, generally without an exit hole due to losing speed when contacting bone structures. The result of this is that the projectile lodges deep in the craniofacial complex, which requires the surgeon to have extensive knowledge and anatomical management for its approach. This article describes a novel technique for projectile removal from the pterygomaxillary fossa, guided by endoscopy through a system of tubular dilators used for minimally invasive spine surgery, in a 14-year-old male patient. After its removal, he continued with remote postoperative controls, without complications, asymptomatic and active in his daily activities, with a minimal scar, and without atrophy of the temporal region. Control imaging studies visualize the correct removal of the foreign body, with adjacent structures without injuries to consider.

Combined open maxillectomy and endoscopic endonasal resection of a giant V2 trigeminal schwannoma.

BACKGROUND: Trigeminal schwannoma is a rare type of tumor that arises from the Schwann cells of the trigeminal nerve. METHOD: We present a case of a patient with a giant V2 trigeminal schwannoma with painful swelling in the left maxilla. A complete resection using a combined open maxillectomy and endoscopic endonasal approach was performed. CONCLUSION: This case highlights the importance of a multidisciplinary approach to perform a combined open and endoscopic approach for safe resection while preserving adequate speech and swallowing.

A comparison of endoscopic procedures performed at a tertiary care hospital before and during the SARS-CoV-2 pandemic.

INTRODUCTION AND AIM: SARS-CoV-2 emerged in 2019 and had a huge impact on the world. The area of endoscopy suffered great changes, causing a reduction in the number of procedures and its indications. The aim of our study was to compare the quantity, indication, and type of procedures in 2019 with those in 2020. METHOD: A retrospective, observational, analytic, and cross-sectional study was conducted, obtaining information from the endoscopy registry. The STROBE checklist was employed. STATISTICAL ANALYSIS: The quantitative variables were analyzed with descriptive statistics (measures of central tendency and dispersion) and the categorical variables with frequencies and percentages. The quantitative variables were compared, using the Student's t test/Mann-Whitney U test, and the categorical variables with contingency tables, using the Fisher's exact test. RESULTS: In 2019, a total of 277 procedures were performed, compared with 139 in 2020. Mean patient age was 98.53 months (61.46 SD) in 2019 and 77.02 months (59.81 SD) in 2020; 352 diagnostic procedures and 136 therapeutic procedures were carried out in 2019, compared with 51 diagnostic procedures and 88 therapeutic procedures in 2020. The number of diagnostic and therapeutic procedures were inverted (72.1%-36.7% and 27.9%-63.3%, respectively) (p<0.0001). Esophageal varices, upper gastrointestinal bleeding (UGIB), and foreign body extraction were the indications, in order of predominance in 2019, compared with foreign body extraction (p<0.05), UGIB, and esophageal varices in 2020. There were no differences regarding colonoscopy. CONCLUSION: There was a clear difference in indication and type of procedure, with an increase in foreign body extraction in preschoolers.

The endoscopic transcanal approach to the internal auditory canal: an anatomic study.

PURPOSE: The internal auditory canal (IAC) plays a key role in lateral skull base surgery. Although several approaches to the IAC have been proposed, endoscope-assisted transcanal corridors to the IAC have rarely been studied. We sought to provide a step-by-step description of the transcanal transpromontorial approach to the IAC and analyze anatomic relationships that might enhance predictability and safety of this approach. METHODS: Ten cadaveric specimens were dissected and the extended transcanal transpromontorial approach to the IAC was established. Various morphometric measurements and anatomic landmarks were reviewed and analyzed. RESULTS: The proposed technique proved feasible and safe in all specimens. There was no inadvertent injury to the jugular bulb or internal carotid artery. The chorda tympani, a key landmark for the mastoid segment of the facial nerve, was identified in all dissections. The spherical recess of the vestibule and middle turn of cochlea are important landmarks for identification of the labyrinthine segment of the facial nerve. Identification of all boundaries of the working area is also essential for safe access. Among various morphometric measurements, the modiolus-IAC angle (≈ 150°) proved particularly consistent; given its ease of use and low variability, we believe it could serve as a landmark for identification and subsequent dissection of the IAC. CONCLUSIONS: The extended transcanal transpromontorial approach to the IAC is feasible and safe. Relying on anatomic landmarks to ensure preservation of the involved neurovascular structures is essential for a successful approach. The modiolus-IAC angle is a consistent, reproducible landmark for IAC identification and dissection.

Navigated Anterior Full-Endoscopic Transcervical Approach Odontoidectomy for Traumatic Posterior Atlantoaxial Dislocation Without Odontoid Fracture.

BACKGROUND AND IMPORTANCE: Complete posterior atlantoaxial dislocation (PAAD) with an unfractured odontoid process is a rare condition where a dislocated but intact odontoid process is positioned ventrally to the anterior arch of C1. This lesion is related to transverse and alar ligament rupture secondary to hyperextension and rotatory traumatic injury and is often associated with neurological deficit. The treatment strategy remains controversial, and in many cases, odontoidectomy is required. Traditional approaches for odontoidectomy (transnasal and transoral) are technically demanding and are related to several complications. This article describes a 360° reduction and stabilization technique through a navigated anterior full-endoscopic transcervical approach (nAFETA) as a novel technique for odontoidectomy and C1-C2 anterior transarticular fixation supplemented with posterior fusion. CLINICAL PRESENTATION: A 21-year-old man presented to the emergency room by ambulance after a motorcycle accident. On evaluation, incomplete ASIA B spinal cord injury was documented. Imaging revealed a complete PAAD. We performed a two-staged procedure, a nAFETA odontoidectomy plus C1-C2 anterior transarticular fixation followed by posterior C1-C2 wired fusion. At a 2-year follow-up, the patient had a 10-point Oswestry Disability Index score and neurological improvement to ASIA E. CONCLUSION: PAAD can be successfully treated through minimally invasive nAFETA. Noteworthy, the risks of the transoral and endonasal routes were avoided through this approach. In addition, nAFETA allows anterior transarticular fixation during the same procedure providing spinal stability. Further studies are required to expand the use of nAFETA in this field.

Validation of a synthetic simulation model of endoscopic rectus sheath plication.

PURPOSE: Literature reviews outline minimally invasive approaches for abdominal diastasis in patients without skin excess. However, few surgeons are trained in endoscopic rectus sheath plication, and no simulated training programs exist for this method. This study aimed to develop and validate a synthetic simulation model for the training of skills in this approach under the Messick validity framework. METHODS: A cross-sectional study was carried out to assess the participants' previous level of laparoscopic/endoscopic skills by a questionnaire. Participants performed an endoscopic plication on the model and their performance was evaluated by one blinded observer using the global rating scale OSATS and a procedure specific checklist (PSC) scale. A 5-level Likert survey was applied to 5 experts and 4 plastic surgeons to assess Face and Content validity. RESULTS: Fifteen non-experts and 5 experts in abdominal wall endoscopic surgery were recruited. A median OSATS score [25 (range 24-25) vs 14 (range 5-22); p < 0.05 of maximum 25 points] and a median PSC score [11 (range 10-11) vs 8 (range 3-10); p < 0.05 of maximum 11 points] was significantly higher for experts compared with nonexperts. All experts agreed or strongly agreed that the model simulates a real scenario of endoscopic plication of the rectus sheath. CONCLUSION: Our simulation model met all validation criteria outlined in the Messick framework, demonstrating its ability to differentiate between experts and non-experts based on their baseline endoscopic surgical skills. This model stands as a valuable tool for evaluating skills in endoscopic rectus sheath plication.

Endoscopic Treatment of Lumbar Degenerative Disc Disease: A Narrative Review of Full-Endoscopic and Unilateral Biportal Endoscopic Spine Surgery.

BACKGROUND: Degenerative lumbar spine disease is the leading cause of disability and work absenteeism worldwide. Lumbar microdiscectomy became the standard treatment for herniated discs and stenotic disease. With the evolution of different techniques, endoscopic spinal surgery emerged to minimize the surgical footprint while providing at least non-inferior results. Currently, two different types of endoscopic spine procedures are dominating the surgical scenario: "Full-Endoscopic" (FE) and Unilateral Biportal Endoscopic" (UBE) Spine Surgery. The aim of this study is to describe and analyze their indications, their technical characteristicswithitsadvantagesanddisadvantagesofbothtechniquesandtheirfuture trends. METHODS: We performed a narrative review of the most relevant articles published up to August 2023 through a Pub Med search. The search terms " FE Spine Surgery" and " UBE Spine Surgery" were used. The articles selected, were independently reviewed by 3 authors and 55 full text articles were reviewed. RESULTS: The FE and UBE Spine Surgery techniques were described. The FE technique is performed with a monoportal access under constant saline irrigation. The FE comprises the transforaminal and the interlaminar approaches, and the indication depends from the pathology to treat, and still remains controversial. UBE can approach also the spine from a posterior, postero lateral,and para spinal route. It uses two different ports addressed to a target with continuous irrigation. The process of establishing these two portals is called triangulation. CONCLUSIONS: FE and UBE spine surgery have demonstrated outcomes comparable to open surgery, minimizing complications and surgical footprint.

Study on Analgesic Effects of Combined Thoracic Paravertebral Block Anesthesia or Erector Spinae Plane Block with Ultrasound Guided Transversus Abdominis Plane Block in Endoscopic Esophagectomy: A Clinical Anatomical Approach / Estudio sobre los Efectos Analgésicos de la Anestesia Combinada con Bloqueo Paravertebral Torácico o el Bloqueo del Plano del Erector de la Columna con Bloqueo del Plano Transverso del Abdomen Guiado por Ultrasonido en la Esofagectomía Endoscópica: Un Enfoque Anatómico Clínico

SUMMARY: The application effect of transversus abdominis plane block (TAPB) combined with thoracic paravertebral block (TPVB) or erector spinae plane block (ESP) under ultrasound guidance in endoscopic radical resection of esophageal cancer under general anesthesia was studied. From March 2021 to February 2022, patients who underwent endoscopic radical resection of esophageal cancer in our hospital were selected as the research object, and 90 patients were selected as the samples. Patients were divided into groupA and group B according to the difference of blocking schemes. Group A received ESP and Group B received TPVB. The dosage of sufentanil, nerve block time, awakening time and extubation time of the two groups were counted. The postoperative pain, sedation effect, sleep satisfaction and analgesia satisfaction of the two groups were compared, and the complications of the two groups were observed. The nerve block time and extubation time in group A were shorter than those in group B (P0.05). At T2, T3 and T4, the visual analogue scale (VAS) scores of group A at rest and cough were significantly lower than those of group B (P0.05). The satisfaction of sleep and analgesia in group A was higher than that in group B (P0.05). The analgesic effect of ultrasound-guided TAPB combined with ESP is better than that of ultrasound-guided TAPB combined with TPVB, and it can shorten the time of nerve block and extubation, which is worth popularizing.

Se estudió el efecto de la aplicación del bloqueo del plano transverso del abdomen (TAPB) combinado con el bloqueo paravertebral torácico (TPVB) o el bloqueo del plano del erector de la columna (ESP) bajo guía ecográfica en la resección radical endoscópica del cáncer de esófago bajo anestesia general. Desde marzo de 2021 hasta febrero de 2022, en nuestro hospital, se seleccionaron como objeto de investigación pacientes sometidos a resección radical endoscópica de cáncer de esófago, y como muestra se seleccionaron 90 pacientes. Los pacientes se dividieron en el grupo A y el grupo B según la diferencia de esquemas de bloqueo. El grupo A recibió ESP y el grupo B recibió TPVB. Se contaron la dosis de sufentanilo, el tiempo de bloqueo nervioso, el tiempo de despertar y el tiempo de extubación de los dos grupos. Se compararon el dolor posoperatorio, el efecto de la sedación, la satisfacción del sueño y la satisfacción de la analgesia de los dos grupos y se observaron las complicaciones de los dos grupos. El tiempo de bloqueo nervioso y el tiempo de extubación en el grupo A fueron más cortos que los del grupo B (P0,05). En T2, T3 y T4, las puntuaciones de la escala visual analógica (EVA) del grupo A en repo- so y tos fueron significativamente más bajas que las del grupo B (P 0,05). La satisfacción del sueño y la analgesia en el grupo A fue mayor que en el grupo B (P0,05). El efecto analgésico de la TAPB guiada por ecografía combinada con ESP es mejor que el de la TAPB guiada por ecografía combinada con TPVB, y puede acortar el tiempo de bloqueo nervioso y extubación, lo que vale la pena popularizar.

Endoscopic thyroidectomy via chest-collarbone approach versus conventional open thyroidectomy: a retrospective comparative study.

OBJECTIVE(S): Endoscopic thyroidectomy, such as axillary, areola and transoral approaches, offer the advantage of a good cosmetic outcome, but it requires a wider dissection field compared to open thyroidectomy. Recently, chest-collarbone approach thyroidectomy has been widely developed in China because of its shorter anatomical route compared to other endoscopic approaches. This study retrospectively evaluated endoscopic thyroidectomy via chest-collarbone approach in patients with thyroid nodules to determine its feasibility. METHODS: A total of 46 patients with thyroid disease who underwent endoscopic thyroidectomy between January 2022 and December 2022 were enrolled in the study and randomly matched to patients with thyroid disease who underwent open thyroidectomy at the same time based on nodule size and pathology. Postoperative bleeding, hoarseness situation, hospital stay, postoperative drainage volume, laryngeal nerve palsy, hypoparathyroidism and wound infection were assessed in both groups. RESULTS: Forty-four patients underwent endoscopic thyroidectomy successfully and two patients changed to open thyroidectomy. The amount of postoperative drainage for the endoscopic thyroidectomy group was 102.78 ±â€¯28.04 mL, and which was 71.91 ±â€¯19.20 for open thyroidectomy group (p < 0.001). The postoperative hospital stay for the endoscopic thyroidectomy group was 8.78 ±â€¯2.57 days, and which was 7.22 ±â€¯1.13 for open thyroidectomy group (p < 0.001). There was no significant difference in postoperative bleeding, hoarseness situation, and wound infection between the two groups. Laryngeal nerve palsy, supraclavicular nerve injury and hypoparathyroidism were not observed in any patient during this study. CONCLUSION: Chest-collarbone endoscopic thyroid surgery is acceptable. This treatment improves in a good cosmetic outcome in patients with thyroid disease. To assess patients with preoperative nodule size and nature of the case is the impact of the success rate, which is particularly important.
