In-office Laryngeal Procedures: a Modern Perspective for Vocal Fold Interventions

Introduction: The purpose of this article is to discuss in-office laryngeal procedures as an alternative to surgical intervention under general anesthesia. In-office procedures have become more common due to technological advancements. As a result, these approaches are less invasive and more patient-friendly, with increased pain tolerance and reduced procedure time and cost. Methods: We conducted a thematic analysis of published reports regarding the best known and performed in-office laryngeal interventions. Three questions guided our analysis: What laryngological procedures can be performed in the office setting? What are the advantages of in-office laryngology procedures compared to operating room surgical procedures? Why aren't more in-office procedures performed in some Latin American countries? Discussion: Despite being performed more frequently, there is still controversy whether in-office procedures should be performed as often due to the risk of complications. Furthermore, procedures that are done in the office setting are more popular in some countries than in others, even though their benefit has been well demonstrated. This article describes various in-office procedures, including biopsy, vocal fold injections, and laser surgery. We also discuss what factors might contribute to having office-procedures being performed more frequently in some countries than others. Conclusion: Awake interventions offer numerous benefits, including shorter procedure time, reduced costs, and lower patient morbidity. These advantages have significantly transformed the treatment of laryngeal diseases in modern laryngology practice in a global manner.

Introducción: El propósito de este artículo es discutir los procedimientos laríngeos en el consultorio como una alternativa a la intervención quirúrgica bajo anestesia general. Los procedimientos en consultorio se han vuelto más comunes debido a los avances tecnológicos. Como resultado, estos enfoques son menos invasivos y más amigables para el paciente, con mayor tolerancia al dolor y reducción del tiempo y costo del procedimiento. Métodos: Realizamos un análisis temático de los informes publicados sobre las intervenciones laríngeas más conocidas y realizadas. Tres preguntas guiaron nuestro análisis: ¿Qué procedimientos laringológicos se pueden realizar en el consultorio y cuales sin los más frecuentes?, ¿cuáles son las ventajas de los procedimientos laringológicos fuera del quirófano frente a los que se realizan bajo anestesia general?, ¿por qué no se realizan más procedimientos laringológicos en el consultorio en la mayoría de los países en Latinoamérica? Discusión: A pesar de que se realizan con mayor frecuencia, aún existe controversia sobre si los procedimientos en consultorio deben realizarse con tanta frecuencia debido al riesgo de complicaciones. Además, los procedimientos que se realizan en el consultorio son más populares en algunos países que en otros, aunque sus beneficios han sido bien demostrados. Este artículo describe varios procedimientos en el consultorio, incluida la biopsia, las inyecciones de cuerdas vocales y la cirugía con láser. También se discutieron los factores que podrían contribuir a que los procedimientos en el consultorio se realicen con más frecuencia en algunos países que en otros. Conclusión: Las intervenciones con pacientes despiertos ofrecen numerosos beneficios, incluido un tiempo de procedimiento más corto, costos reducidos y una menor morbilidad para el paciente. Estas ventajas han transformado significativamente el tratamiento de las enfermedades laríngeas en la práctica de la laringología moderna a nivel mundial.

Clinical and histopathological factors for recurrence and metastasis in lacrimal gland adenoid cystic carcinoma in Chinese patients.

PURPOSE: To investigate the association of metabolism-related proteins and clinicopathological features with poor prognosis in lacrimal gland adenoid cystic carcinoma (LGACC). METHODS: Clinicopathological data for 39 Chinese patients with LGACC enrolled were retrospectively analysed. Disease progression included death, recurrence, further nodal metastasis, and distant metastasis. Expression of ASCT2 and GLS1 were evaluated by immunohistochemistry. Kaplan-Meier survival curves and Cox proportional hazards regression models were used for risk factor analyses. RESULTS: At the end of follow-up, 14 patients (35.9%) developed local recurrence, 13 patients (33.3%) developed distant metastasis, 3 patients (7.7%) developed lymph node metastasis, and 9 patients (23.1%) died. Among the 13 patients who developed distant metastasis, lung metastasis was observed in 8 patients (61.5%), the brain in 8 patients (61.5%), and bone in 1 patient (7.7%). ASCT2 was expressed in 16 (57.14%) cases, while GLS1 had high expression in 19 (67.9%) cases. Advanced T category (≥T3), bone erosion, basaloid subtype, and ASCT2 (-) were associated with disease progression. Basaloid subtype was an independent risk factor for local recurrence (P = 0.028; HR, 12.12; 95% CI, 1.3-111.5). ASCT2(-) was an independent risk factor for distant metastasis (P = 0.016; HR, 14.46; 95% CI, 1.6-127.5) and was associated with basaloid subtype (P = 0.019). CONCLUSIONS: For LGACC, ≥T3 category, basaloid subtype, and bone erosion were high-risk predictors. ASCT2(-) was an independent risk factor for distant metastasis, which suggested that it could be a potential biomarker for LGACC.

Intraoperative bladder visualization by indocyanine green filling and subsequent washout in endoscopic hysterectomy: ICG-Washout method.

INTRODUCTION: Despite a potential risk of bladder injury in laparoscopic hysterectomy (LH) and robot-assisted LH (RaLH), an intraoperative method for delineating the entire bladder with indocyanine green (ICG) has not been established. METHODS: We conducted a preliminary experiment using porcine bladders to verify the appropriate amount of ICG for intraoperative bladder visualization. Afterward, intraoperative bladder visualization was tried in LH and RaLH in two patients suspected of having adhesions around the bladder after previous abdominal surgery. RESULTS: Although near-infrared (NIR) fluorescence was well observed through the wall of the porcine bladder filled with ICG solution at a concentration of 0.024 mg/mL, the subsequent replacement of the ICG solution with saline made the NIR fluorescence brighter. In both patients, the bladder was successfully delineated by NIR fluorescence after filling the bladder with ICG solution and the subsequent washout with saline. CONCLUSION: The ICG-Washout method for locating the bladder by NIR fluorescence could be useful in LH and RaLH.

Unilateral laser ventriculocordectomy results in increased arytenoid stability in horses with severe left sided recurrent laryngeal neuropathy.

BACKGROUND: There is no objective information reporting the effect of unilateral laser ventriculocordectomy (VeC) on arytenoid abduction or stability. OBJECTIVES: To evaluate arytenoid stability and abduction in horses with severe recurrent laryngeal neuropathy (RLN) before and after unilateral laser VeC. STUDY DESIGN: Prospective cohort. METHODS: Eight horses with grade C or D exercising laryngeal function that underwent unilateral laser VeC were included. Exercising endoscopy was performed before and ≥6 weeks after left-sided laser VeC. Arytenoid stability at maximal exercise was calculated by measuring the left-to-right quotient angle ratio (LRQ) of the corniculate processes at the points of maximal arytenoid abduction (expiration) and maximal arytenoid collapse (inspiration). For each horse, means of measurements obtained for four breaths pre- and post-operatively were used for statistical analysis. RESULTS: The difference in LRQ between inspiration and expiration was lower post-operatively (median 0.039; interquartile range [IQR] 0.032-0.047) compared with pre-operatively (median 0.158; IQR 0.083-0.249; p = 0.01) confirming the left arytenoid was more stable following unilateral laser VeC. The degree of improvement was significantly greater for grade D horses compared with grade C horses (p = 0.04). The LRQ measured on maximal abduction was also lower post-operatively (median 0.467; IQR 0.444-0.506) compared with pre-operatively (median 0.578; IQR 0.554-0.655; p = 0.02) indicating the left arytenoid was less abducted following surgery. MAIN LIMITATIONS: The sample size was small, no racehorses were included and post-operative assessment was conducted at a variable time after surgery. CONCLUSION: Unilateral laser VeC in grade C and D RLN-affected horses results in slightly reduced left arytenoid abduction but increased arytenoid stability.

Bichectomy Surgery and EMG Masticatory Muscles Function in Adult Women: A Longitudinal Study.

AIM: This longitudinal study aimed to evaluate the electromyographic activity of the masseter and temporal muscles in adult women who underwent buccal fat removal. MATERIALS AND METHODS: The sample consisted of 20 healthy adult women with no temporomandibular dysfunction and normal occlusion, who were assessed before, 30, and 60 days after the surgery. The electromyographic signal of the masseter and temporal muscles was captured through mandibular tasks including rest, protrusion, right and left laterality, and maximum voluntary contraction with and without parafilm. The results obtained were tabulated and the Shapiro-Wilk normality test was performed, which indicated a normal distribution. Statistical analysis was performed using the repeated measures test (p < 0.05). RESULTS: Significant differences were observed between time periods in maximum voluntary contraction for the left masseter muscle (p = 0.006) and in maximum voluntary contraction with parafilm for the right temporal (p = 0.03) and left temporal (p = 0.03) muscles. CONCLUSION: Bichectomy surgery did not modify the electromyographic activity of the masseter and temporal muscles during the rest task but may have influenced variations in the electromyographic signal during different mandibular tasks after 60 days of surgery, suggesting compensatory adaptations and functional recovery. CLINICAL SIGNIFICANCE: Understanding the impact of buccal fat removal surgery on the stomatognathic system function provides insights into postoperative functional recovery and potential compensatory adaptations, guiding clinical management and rehabilitation strategies for patients undergoing such procedures.

The value of surgery and the prognostic factors for patients with recurrent low-grade endometrial stromal sarcoma: a retrospective study of 38 patients.

OBJECTIVE: As an indolent malignant tumor, the long-term management of low-grade endometrial stromal sarcoma (LGESS) patients required awareness, especially the management of recurrences. Unfortunately, few studies focused on the treatment of recurrent LGESS. Our study aimed to investigate the prognostic factors and the value of recurrent surgery on recurrent LGESS. METHODS: This retrospective study consecutively recruited patients with pathologically diagnosed recurrent LGESS at our center from April 1, 2004 to April 1, 2020. RESULTS: After a median follow-up of 137.0 months (95% confidence interval=85.4-188.6), the 5-year cumulative survival rate of the cohort of 38 patients with recurrent LGESS was 71.1%. The median overall survival (OS) and post-recurrence survival (PRS) was 156 and 89.0 months. Survival analysis showed that patients with younger age, positive estrogen receptor (ER) and optimal abdominopelvic debulking in the first recurrent surgery had better prognosis (p<0.05). Multivariate analysis showed that optimal abdominopelvic debulking in the first recurrent surgery was the only independent prognostic factor for OS and PRS (OS=216.0/35.0 months, hazard ratio [HR]=5.319, p=0.034; PRS=not reached/4.0 months, HR=10.900, p=0.006). There was no significant difference in OS and PRS between patients recurred only once and those recurred at least twice (p>0.05). CONCLUSIONS: The prognosis of recurrent LGESS was favorable. Optimal debulking of no residual tumor in abdominal and pelvic cavity should be the first choice of treatment for recurrent patients, while preservation of ovary or fertility should not be recommended.

Single-Port Robotic Trans-Subxiphoid Surgery for Anterior Mediastinal Disease: A Pilot Trial.

OBJECTIVE: In recent years, there has been an increasing focus on minimally invasive mediastinal surgery using a trans-subxiphoid single-port thoracoscopic approach. Despite its potential advantages, the widespread adoption of this method has been hindered by the intricate surgical maneuvers required within the confined retrosternal space. Robotic surgery offers the potential to overcome the limitations inherent in the thoracoscopic technique. METHODS: This was a clinical trial (NCT05455840) to evaluate the feasibility and safety of utilizing the da Vinci® SP system (Intuitive Surgical, Sunnyvale, CA, USA) for trans-subxiphoid single-port surgery in patients with anterior mediastinal disease. The primary endpoints encompassed conversion rates and the secondary endpoints included the occurrence of perioperative complications. RESULTS: Between August 2022 and April 2023, a total of 15 patients (7 men and 8 women; median age = 56 years, interquartile range [IQR]: 49 to 65 years) underwent trans-subxiphoid robotic surgery using da Vinci SP platform for maximal thymectomy (n = 2) or removal of anterior mediastinal masses (n = 13). All surgical procedures were carried out with success, with no need for conversion to open surgery or the creation of additional ports. The median docking time was 2 min (IQR: 1 to 4 min), while the console time had a median of 152 min (IQR: 95 to 191 min). There were no postoperative complications and patients experienced a median postoperative hospital stay of 2 days with no unplanned 30-day readmission. CONCLUSIONS: This study shows that trans-subxiphoid single-port robotic surgery employing the da Vinci SP system in patients with anterior mediastinal disease is clinically viable with acceptable safety and short-term outcomes.

Robot-Assisted Bronchoscopy for Identification of Lung Nodules During Minimally Invasive Pulmonary Resection.

OBJECTIVE: Small pulmonary nodules can be difficult to identify during minimally invasive surgical (MIS) resection. Previous investigators have reported using standard bronchoscopy with electromagnetic navigation to identify small pulmonary nodules. Robot-assisted bronchoscopy has been introduced into clinical practice and has shown utility for the biopsy of small lesions. We report our experience using robot-assisted bronchoscopy with dye marking to aid in minimally invasive pulmonary resection. METHODS: Patients with peripheral pulmonary nodules underwent robot-assisted bronchoscopy before a planned minimally invasive resection. Indocyanine green or methylene blue was injected directly into the targeted lesion. Surgical resection was then immediately performed. Success was defined as dye visualization leading to sublobar resection of the target nodule without the need for lobectomy or thoracotomy. RESULTS: Thirty patients with a single targeted nodule underwent robot-assisted bronchoscopy followed by MIS resection. The median lesion size was 9 mm (4 to 25 mm), and the median distance from the pleura was 5 mm (1 to 32 mm). The success rate was 83.3% (25 of 30). There were 3 cases in which the dye was not visualized, and in 2 cases there was free extravasation of dye. The targeted nodule was identified in these 5 patients without the need for thoracotomy or lobectomy. Pathology revealed non-small cell lung cancer (n = 13, 43.3%), metastatic disease (n = 11, 36.7%), and benign disease (n = 6, 20%). There were no complications related to the use of robot-assisted bronchoscopy. CONCLUSIONS: Robot-assisted bronchoscopy with dye marking is safe and effective for guiding minimally invasive resection of small peripheral pulmonary nodules.

Anatomical study of the relationship between the lumbar intervertebral disc, nerves, and psoas major.

Cadaveric study; To describe the characteristics of the nerve and its relationship with the lumbar intervertebral disc and psoas major muscle. Nerve injury is an understudied complication of extreme lateral interbody fusion. A detailed description of the nerve anatomy would be helpful for surgeons to minimize the risk of this complication. The lumbar plexus and lumbar sympathetic nerve of 10 embalmed male cadavers were dissected, and the distribution, number, and spatial orientation of the nerves on the L1/2 to L4/5 intervertebral discs were examined. Metal wires were applied along nerve paths through the psoas major muscle. The position of the nerves was examined on CT. In zone III at L1/2 and L4/5, no nerves were found. In zone II and zone III at L2/3, no lumbar plexus was found, and only the ramus communicans passed through. At the L1-L5 level, the density of nerves in the posterior half of the psoas major muscle was greater than that in the anterior half. The lumbar plexus was found in all of zone IV. The genitofemoral nerve emerges superficially and anteriorly from the medial border of the psoas major at the L3-4 level, but at the L1/2 level, the sympathetic trunk is located in zone II. The remaining disc-level sympathetic trunks appear in zone I. No nerves were found in zone III of the L1/2 or L4/5 disc. In zones II and III of L2/3, the lumbar plexus appears safe. The genitofemoral nerve travels through zones II and III of L3/4. The distribution density of nerves in the posterior half of the psoas major muscle was greater than that in the anterior half of that muscle at the L1-L5 level.

Persistent Severe Headache After Removal of Fungus Ball From the Sphenoid Sinus: A Case Report.

OBJECTIVE: Granulomatous invasive fungal sinusitis (GIFS) is a rare and life-threatening disease, whereas fungus ball (FB) is the most common form of noninvasive fungal sinusitis. Both GIFS and FB primarily develop in immunocompetent patients, with the former associated with higher mortality and morbidity. METHODS: A chart review and review of the literature. RESULTS: We present the case of a 77-year-old woman with mixed fungal sinusitis who was successfully treated with voriconazole. CONCLUSIONS: GIFS and FB can coexist in extremely rare cases, known as mixed fungal sinusitis; however, the diagnosis and subsequent treatment of mixed fungal sinusitis can be delayed because of a lack of awareness of the underlying concept. Therefore, it is crucial for clinicians to recognize the concept of mixed fungal sinusitis.

Implementation of a geriatric in-reach service improves acute surgical unit outcomes; a retrospective before-and-after study.

BACKGROUND: Australia's ageing population is challenging for surgical units and there is a paucity of evidence for geriatric co-management in acute general surgery. We aimed to assess if initiating a Geriatric Medicine in-reach service improved outcomes for older adults in our Acute Surgical Unit (ASU). METHODS: The Older Adult Surgical Inpatient Service (OASIS) was integrated into ASU in 2021. We retrospectively reviewed all patients over age 65 admitted to ASU over a 12-month period before and after service integration with a length of stay (LOS) greater than 24 h. There was no subsequent truncation or selection. Primary outcomes were 30-day mortality, LOS, and 28-day readmissions. Secondary outcomes were discharge disposition, in-hospital mortality, and hospital-acquired complications (HACs). RESULTS: 1339 consecutive patients were included in each group, with no differences in baseline characteristics. There was a significant decrease in 28-day readmissions from 20.2% to 16.0% (P < 0.05), greatest in patients undergoing non-EL operative procedures (21.9% pre-OASIS vs. 12.6% post-OASIS; P < 0.05). Trends towards reduced 30-day mortality (7.17% vs. 5.90%; P = 0.211), in-hospital mortality (3.88% vs. 2.91%; P = 0.201), permanent care placement (7.77% vs. 7.09%; P = 0.843) and HACs (8.14% vs. 7.62%; P = 0.667) were seen, although statistical significance was not demonstrated. LOS remained unchanged at 4 days (P = 0.653). CONCLUSION: The addition of a geriatric in-reach service to a tertiary ASU led to a significant reduction in 28-day readmissions. Downtrends were seen in mortality, permanent care placement, and HAC rates, while LOS remained unchanged.

Randomized Controlled Trial of Awake Transnasal Laser-Assisted Surgery for Benign Laryngeal Lesions.

OBJECTIVE: To compare functional and cost-effectiveness of awake transnasal laser assisted-surgery versus microlaryngeal surgery for benign laryngeal lesions. METHODS: This was a prospective non-inferiority randomized controlled trial conducted from May 2021 to December 2022 at two tertiary referral hospitals in Hong Kong. Patients were block-randomized to receive either awake transnasal laser-assisted surgery or microlaryngeal surgery, with post-operative follow-up in a multidisciplinary voice clinic for 1-year. Primary outcome was Voice Handicap Index (VHI-30). Secondary outcomes included operation time, complications, length of stay, peri-operative discomfort, recurrence, and medical costs. RESULTS: Sixty-one patients were randomized to either awake transnasal laser-assisted surgery (n = 30) and microlaryngeal surgery (n = 31). Both groups had comparable demographics and laryngeal pathologies. Both groups showed significant improvement of VHI-30 score over time and had comparable post-operative VHI-30. Awake transnasal laser-assisted surgery group had a significantly shorter length of stay (0.5 vs. 1 day) and less throat discomfort (2 vs. 4) compared to microlaryngeal surgery group. Intraoperative complications were more common in microlaryngeal surgery group (14.3% vs. 0%). Otherwise, both groups had similar operative time and recurrence rate. Cost-analysis showed a significantly lower hospital cost for awake transnasal laser-assisted surgery (USD 3090) compared to microlaryngeal surgery group (USD 5120). CONCLUSION: Awake transnasal laser-assisted surgery was safe, functionally non-inferior, as measured by VHI-30, to microlaryngeal surgery in managing benign laryngeal lesions, while superior to microlaryngeal surgery in peri-operative discomfort and medical costs. LEVEL OF EVIDENCE: Level 2 Laryngoscope, 2024.

Comparison of pregnancy outcomes after bariatric surgery by sleeve gastrectomy versus gastric bypass.

Objective: Bariatric surgery has an impact on subsequent pregnancies, in particular an association between gastric bypass and small for gestational age. Knowledge is lacking on whether sleeve gastrectomy is associated with more favorable pregnancy outcomes. This study aimed to compare the impact of sleeve gastrectomy and Roux-en-Y gastric bypass on the incidence of small for gestational age (SGA), and of adverse pregnancy outcomes. Study design: We conducted a retrospective study in a single reference center, including all patients with a history of sleeve or bypass who delivered between 2004 and 2021 after their first pregnancy following bariatric surgery. We compared the incidence of SGA, intrauterine growth retardation, preterm delivery and adverse maternal outcomes between patients who had sleeve versus bypass. Results: Of 244 patients, 145 had a sleeve and 99 had a bypass. The proportion of SGA < 10th percentile did not differ between the two groups (38/145 (26.2 %) vs 22/99 (22.22 %), respectively, p = 0.48). Preterm birth < 37 WG was lower in the sleeve group (5/145 (3.45%) vs 12/99 (12.12 %) in the bypass group (p = 0.01), as well as NICU hospitalizations (3 (2.07%) vs 12/99 (12.12%), p < 0.01). There was no difference regarding adverse maternal outcomes such as gestational diabetes and hypertensive complications. The proportion of SGA was not lower in patients with bypass when adjusting for other risk factors (BMI, smoking, geographic origin, diabetes and hypertension) (aOR 0.70; 95%CI 0.01 - 2.85). Conclusion: sleeve was associated with an incidence of SGA which was as high as after bypass, however the incidence of preterm birth was lower.

Should an Incidental Meckel Diverticulum Be Resected? A Systematic Review.

Background: Meckel Diverticulum [MD), a common congenital anomaly of the gastrointestinal tract, poses a dilemma when incidentally encountered during surgery. Despite historical descriptions and known complications of symptomatic MD, the decision to resect an incidental MD (IMD) lacks clear guidelines. This study aims to assess whether resecting IMDs is justified by synthesizing evidence from studies published between 2000 and 2023. Factors influencing this decision, such as demographic risks, surgical advancements and complications, are systematically examined. Methods and Material: Following the PRISMA 2020 guidelines, this review incorporates 42 eligible studies with data on outcomes of asymptomatic MD management. Studies, both favoring and opposing resection, were analyzed. Results: Considering complications, malignancy potential, and operative safety, the risk-benefit analysis presents a nuanced picture. Some authors propose conditional resection based on specific criteria, emphasizing patient-specific factors. Of 2934 cases analyzed for short- and long-term complications, the morbidity rate was 5.69%. Of 571 cases where mortality data were available, all 5 fatalities were attributed to the primary disease rather than IMD resection. Conclusion: The sporadic, unpredictable presentation of IMD and the variability of both the primary disease and the patient make formulation of definitive guidelines challenging. The non-uniformity of complications reporting underscores the need for standardized categorization. While the balance of evidence leans towards resection of IMDs, this study acknowledges the individualized nature of this decision. Increased safety in surgery and anesthesia, along with better understanding and management of complications favor a judicious preference for resection, while taking into account patient characteristics and the primary disease.

Immune analysis of urine and plasma samples from patients with clear cell renal cell carcinoma.

Clear cell renal cell carcinoma (ccRCC) is the third most common type of urological malignancy worldwide, and it is associated with a silent progression and late manifestation. Patients with a metastatic form of ccRCC have a poor prognosis; however, when the disease is diagnosed early, it is largely curable. Currently, there are no biomarkers available in clinical practice for ccRCC. Thus, the aim of the present study was to measure 27 biologically relevant cytokines in preoperative and postoperative urine samples, and in preoperative plasma samples from 34 patients with ccRCC, and to evaluate their diagnostic significance. The concentrations of cytokines were assessed by multiplex immune assay. The results showed significantly higher levels of IL-1 receptor antagonist, IL-6, IL-15, chemokine (C-C motif) ligand (CCL)2, CCL3, CCL4, C-X-C motif ligand (CXCL)10, granulocyte-macrophage colony stimulating factor (GM-CSF) and platelet-derived growth factor-BB (PDGF-BB), and lower levels of granulocyte colony stimulating factor (G-CSF) in urine samples from patients prior to surgery compared with those in the controls. Notably, the urine levels of G-CSF, IL-5 and vascular endothelial growth factor differed following tumor removal compared with the preoperative urine levels. In addition, urinary G-CSF, GM-CSF, IL-6, CXCL10, CCL5 and PDGF-BB appeared to be potential markers of tumor grade. Plasma from patients with ccRCC contained significantly higher levels of IL-6 and lower levels of CCL2 than control plasma. In conclusion, the present findings indicated that urinary and circulating cytokines may represent a promising novel tool for the early diagnosis of ccRCC and/or prediction of tumor grade.

Surgical training in extraperitoneal laparoscopic para­aortic lymphadenectomy for the treatment of gynecological cancer using a Thiel­embalmed cadaver.

The extraperitoneal laparoscopic approach (ELPAN) for para-aortic lymphadenectomy provides excellent visibility of the left side of the aorta, thus facilitating surgery in the retroperitoneal space. This technique is highly complex compared with the transperitoneal approach. In particular, advanced techniques are required to develop an appropriate surgical field in the narrow retroperitoneal space; therefore, surgeons need to undergo a significant amount of training to become competent. A variety of tools are available for surgical training but are limited by their ability to reproduce complex anatomy. Thus, cadavers may represent the most suitable tool for learning this unique technique. The present study describes a surgical training protocol for the ELPAN technique using a Thiel-embalmed human cadaver and provides a step-by-step description of the ELPAN technique performed at Okayama University (Okayama, Japan). A 72-year-old Thiel-embalmed female cadaver was used to develop a protocol for surgical training in the ELPAN technique that effectively reproduced the methodology required in clinical practice. A training method for ELPAN surgery was developed and successfully completed using the Thiel-embalmed cadaver that secured the surgical field in the retroperitoneal space and permitted resection of the lymph nodes. The Thiel-embalmed cadaver tissue possessed excellent properties for surgical training, including color tone, flexibility, and the membrane structure of connective and fat tissues. In addition, this method of fixation preserved stiffness and elasticity of the peritoneum, although large vessels were slightly fragile and poorly extensible. Surgical training using a Thiel-embalmed human cadaver represents a valuable option for learning the ELPAN surgical technique. However, this technique may be unsuitable for training in perivenous manipulation. To the best of our knowledge, this is the first report to describe the use of Thiel-embalmed cadavers as a tool for surgeons to undergo training in the ELPAN technique.

Pleural Epithelioid Hemangioendothelioma: An Ultrarare Cause for Recurrent Pleural Effusion Managed With Trametinib and Pazopanib.

Epithelioid hemangioendothelioma (EHE) is an extremely rare sarcoma of vascular origin. Primary pleural involvement is extremely under-reported and tends to have a more aggressive course. We report a case of pleural EHE in a Caucasian female in her 50s with a two-month history of dyspnea and chest pain. Investigations, including video-assisted thoracoscopy, revealed extensive pleural scarring and inflammation. Management with trametinib and pazopanib led to a stable disease course, reduction in the frequency of pleural effusion recurrence, and improvement in cancer-related pain.

Micro-face-lift: A novel biplanar, composite, less-invasive procedure.

Background: Facial rejuvenation procedures have been in existence for over a century. Since its first introduction, it improved anatomical understanding and clinical implications and gave rise to numerous techniques and re-ideations of the original face-lift. The increase in popularity of face-lift procedures attracts patients of various ages and with different medical comorbidities. In this paper, we describe the less-invasive facelift procedure, termed the "Micro-Face-lift," with minimal complications, a short recovery period, and few contraindications. Materials and Methods: The authors retrospectively analyzed the medical files of 51 patients who underwent the "Micro-Face-lift" procedure between 2014 and 2019 by three independent surgeons. Results: Fifty-one patients met the inclusion criteria for the procedure. Forty-nine patients were women (96.1%) and the remainder were men (3.9%). The mean age at the time of the procedure was 60.8 years (range 45-87). Complications were encountered in five patients (9.8%): two hypertrophic scars (3.8%), one hematoma (2%), one surgical wound infection (2%), and one edema (2%), persistent for more than 2 weeks postoperatively. All complications resolved within 6 weeks of postoperatively. Thirty-five patients (68.6%) underwent additional procedures to maximize the aesthetic outcome. Thirty patients (58.8%) underwent submental liposuction and five patients (9.8%) underwent mid-face lipo-filling. The average satisfaction score on the self-reported "Likert" scale was 4.27 (range 1-5). All patients were followed for a minimum period of 18 months. Conclusions: The "Micro-Face-lift" is a less-invasive procedure that can be performed under local anesthesia and sedation in the outpatient setting. Complication rates and mortality are low, contraindications are rare, and the recovery period is short. In our experience, patient satisfaction is high with the Micro-Face-lift procedure, and the learning curve for the experienced practitioner is short.

Advantages and caveats of endoscopic to the infratemporal fossa as isolated and combined techniques.

Objective: Identify the benefits and caveats of combining minimal access approaches to the infratemporal fossa (ITF), such as the endoscopic transnasal, endoscopic transorbital, endoscopic transoral, and endoscopic sublabial transmaxillary approaches to address extensive lesions not amenable to a single approach. The study provides anatomical metrics including area of exposure and degree of surgical freedom. Methods: Five human cadaveric specimens (10 sides) were dissected to expose and methodically analyze the anatomical intricacies of the ITF using the following minimal access approaches: endoscopic transnasal transpterygoid (EETA), endoscopic sublabial transmaxillary, endoscopic transorbital via infraorbital foramen, and endoscopic transoral techniques. Area of exposure at the pterygopalatine fossa and surgical freedom at the ITF were obtained for each approach. Results: The endoscopic sublabial transmaxillary sinus and the combined approach afford a significantly greater exposure than an isolated EETA. The difference in exposure (mean) between the endoscopic sublabial transmaxillary and EETA was 1.62 ± 0.85 cm2 (p < 0.001), and the difference between the combined approach and EETA was 4.25 ± 0.85 cm2 (p < 0.001). Conclusions: Combining minimal access endoscopic approaches to the ITF can provide significantly greater exposure than an isolated EETA; thus, providing enhanced access to address lesions with extensive involvement of the ITF, especially those with superolateral and inferolateral extensions. In addition, some approaches may have an adjunctive role to the resection, such as the endoscopic transoral approach offering the potential for early control of the internal maxillary artery and its branches, some of which may be supplying the tumor in the ITF; or the endoscopic transorbital approach yielding a direct line of sight to the superior ITF and middle cranial fossa. Level of Evidence: NA.

Local Flaps in Breast-Conserving Surgery in Early Breast Cancer Patients: Armamentarium for Breast Surgeon.

To describe the technique and outcome of local perforator arteries advancement flap in breast-conserving surgeries (BCS) in patient of early breast cancer as our initial experience and review of literature on it. Patients who underwent (BCS) with local perforator artery flap reconstruction were reviewed in terms of their clinical, surgical, and post-operative follow-up details after taking written and informed consent. We have described 4 patients of early breast cancer out of which one patient was post-NACT while 3 were for upfront BCS. We have performed LICAP in 2 patients, AICAP in 1 patient, and IMAP in one patient, depending on the location of primary tumors. None of the patients had any major or minor surgical complications in the post-operative period and drains were removed on post-operative day 2. All patients received post-operative radiotherapy and tolerated well without any loco-regional complications. Patients are in routine follow-up with cosmetic satisfaction without any local recurrence over 1 year. The main advantages of pedicled perforator flaps are well-vascularized tissue, spares underlying muscle leading to lesser donor site morbidity like muscle function and seroma formation, easily reach the breast area with good match in terms of skin and subcutaneous tissue, faster recovery, and shorter learning curve in comparison to free flaps. Knowledge and skill about these flaps will help surgeon to give better surgical outcomes and satisfaction to patients.
