Extended cervical approach for retrosternal multinodular goiter.

Objective: Partial or total sternotomy is required for 10% of retrosternal goiter. This study reviewed our experience with an extended cervicotomic approach as an alternative surgical solution for retrosternal goiter. Methods: A retrospective study was performed on patients who underwent partial or total thyroidectomy for retrosternal goiter between 2014 and 2019 at a tertiary medical centre. Data on clinical, radiologic, and pathologic factors were analysed. Peri- and postoperative outcomes were compared between extended and standard cervical approaches to predict the need for an extended cervical approach. Results: The cohort included 265 patients, of whom 245 (92.4%) were treated by standard thyroidectomy. In 17 (6.4%), the standard approach proved insufficient, and the horizontal incision was extended to a T-shape to improve access. The remaining 3 patients required a sternotomy. Use of the extended cervical approach was significantly associated with clinical features such as male gender, diabetes, high body mass index and postoperative hypocalcaemia. Conclusions: The extended cervicotomic approach is an alternative surgical solution for retrosternal goiter, with no increased risk of significant post-operative complications.

[SURGICAL TREATMENT VERSUS ENDOSCOPIC TREATMENT FOR ACHALASIA IN THE MODERN ERA].

INTRODUCTION: Achalasia is a disorder of esophageal motility characterized by absent relaxation of the lower esophageal sphincter and abnormal peristalsis of the esophagus during swallowing. The etiology is divided into primary idiopathic achalasia and secondary achalasia and classified into 3 subtypes based on manometric evaluation, according to the Chicago 4.0 classification. The goal of the therapy is symptomatic improvement and prevention of late complications. While there are several endoscopic therapies, the gold standard therapy is laparoscopic Heller myotomy. Since its debut in 2008, per-oral-endoscopic-myotomy (POEM) became an accepted treatment for achalasia with non-inferior short term outcomes compared to Heller myotomy. In the following review, we will explore the indications, guidelines, and controversies in the modern treatment of achalsia, focusing on the Heller myotomy versus POEM.

Post-radiotherapy osteomyelitis of the cervical spine in head and neck cancer patients.

Objective: To evaluate patient characteristics, risk factors, disease course, and management of cervical vertebral osteomyelitis in patients who had radiation for head and neck cancers. Methods: A retrospective cohort study (case series) of patients diagnosed with post-radiation osteomyelitis of the cervical spine between 2012 and 2021. Data were collected from the patient's medical files. Results: Seven patients (71% male) with post-radiation cervical osteomyelitis were reviewed. The median patient age was 64 years. The mean interval between diagnosis of osteomyelitis and the first and last radiotherapy course was 8.3 and 4.0 years, respectively. A medical or surgical event preceded the diagnosis in four patients (57%) by a mean of 46.25 days. Common imaging findings were free air within the cervical structures and fluid collection. Four patients recovered from osteomyelitis during the follow-up within an average of 65 days. Conclusion: Post-radiation osteomyelitis is characterized by a subtle presentation, challenging diagnosis, prolonged treatment, and poor outcome. Clinicians should maintain a high index of suspicion for the long-term after radiotherapy. Multidisciplinary evaluation and management are warranted. Advances in knowledge: The study describes post-radiotherapy osteomyelitis of the cervical spine, a rare and devastating complication. Literature data regarding this complication are sparse.

A Novel Urine Test Biosensor Platform for Early Lung Cancer Detection.

Lung cancer is the leading cause of cancer-related mortality worldwide. Early detection is essential to achieving a better outcome and prognosis. Volatile organic compounds (VOCs) reflect alterations in the pathophysiology and body metabolism processes, as shown in various types of cancers. The biosensor platform (BSP) urine test uses animals' unique, proficient, and accurate ability to scent lung cancer VOCs. The BSP is a testing platform for the binary (negative/positive) recognition of the signature VOCs of lung cancer by trained and qualified Long-Evans rats as biosensors (BSs). The results of the current double-blind study show high accuracy in lung cancer VOC recognition, with 93% sensitivity and 91% specificity. The BSP test is safe, rapid, objective and can be performed repetitively, enabling periodic cancer monitoring as well as an aid to existing diagnostic methods. The future implementation of such urine tests as routine screening and monitoring tools has the potential to significantly increase detection rate as well as curability rates with lower healthcare expenditure. This paper offers a first instructive clinical platform utilizing VOC's in urine for detection of lung cancer using the innovative BSP to deal with the pressing need for an early lung cancer detection test tool.

The Whiteboard Time Out: A Novel Tool to Improve Resident Learning in the Operating Room.

OBJECTIVE: "Flipping the classroom" is a strategy that has been implemented in various educational environments to create a student-centered learning environment. Within this model of teaching, "first exposure" occurs prior to the classroom in a lower form of cognitive demand, allowing students to employ higher forms of cognition within the classroom. Surgical education has evolved over recent years to incorporate different modalities of learning; however, optimal educational approaches within the operating room (OR) have not been clearly defined. The Whiteboard Time Out (WBTO) utilizes the idea of "flipping the classroom" to make learning within the OR more resident centered. Residents complete most of the preoperative work prior to the case with a focus on the indications, steps of the procedure, and potential complications associated with the procedure. Residents then utilize a whiteboard located in the OR to outline, diagram, and discuss this information with the attending. Aims of the study are to enhance higher level intraoperative resident learning and attending teaching and improve resident knowledge and the ability to communicate surgical steps. DESIGN: Faculty and residents completed a preimplementation questionnaire aligned to the Student Evaluation of Educational Quality (SEEQ) in July 2021. Participants were assigned 3 digit codes to ensure anonymity. The questionnaire was composed of 6 questions with a 5-point Likert scale. Whiteboards were mounted in every operating room, 19 total, in both the general OR and an ambulatory surgical center. The residents were expected to go to the OR, prior to scrubbing the case, and use the whiteboard to outline the indications, key steps and potential complications. After the resident completed the white board, the resident and attending reviewed the white board together prior to the start of the case. After the procedure, residents uploaded a picture of the whiteboard with a self-evaluation and faculty provided resident feedback via an online Wufoo Survey link. The start of the utilization of the whiteboards occurred after the initial survey in July 2021. The SEEQ questionnaire was again administered in October 2021, 3 months post-WBTO implementation, to assess resident and attending satisfaction. SEEQ questionnaire results were compared using a t-test. PARTICIPANTS: Participants included surgical residents and attendings at Maimonides Medical Center (MMC). MMC is a 700-bed university-affiliated, academic, tertiary medical center in Brooklyn, New York. The General Surgery Residency is approved for up to 5 graduates annually. RESULTS: A total of 17 attendings and 17 residents filled out the questionnaire. The average number of whiteboards completed was highest amongst the PGY1 class with an average of 18 whiteboards per resident. However, the average number of whiteboards completed declined amongst more senior residents. There was a statistically significant increase in overall SEEQ survey score amongst residents and attendings after implementation of the WBTO suggesting that whiteboards were useful (p < 0.03 and p < 0.02, respectively). Residents found that the whiteboard was an effective means of teaching surgical education compared to the current curriculum (p < 0.04). CONCLUSIONS: The whiteboard timeout is a tool created to enhance resident education in the OR. This idea is centered on a "flipped classroom," an educational strategy to increase student engagement. Our data demonstrates that the whiteboard timeout is an effective method of intraoperative teaching.

Thyroid-split tracheostomy: short- and long-term outcomes.

Objective: Compare long-term outcomes of thyroid-split and standard thyroid-retraction tracheostomy in a large cohort. Methods: The healthcare database of a university-affiliated hospital was searched for past patients over 18 years of age from all of the hospital's wards on whom an ear, nose, and throat specialist performed a tracheostomy in the operating room between 2010 and 2020. Clinical data were extracted from the hospital and outpatient medical records. Life-threatening and non-life-threatening intra-operative and early and late post-operative adverse events in patients who underwent split-thyroid tracheostomy were compared with those who underwent standard tracheostomy. Results: There was no significant difference in intra-operative and early post-operative complications, hospitalisation length, or early reoperation and death rates between the 140 (28%) thyroid-split tracheostomy patients and the 354 (72%) standard tracheostomy patients, although the thyroid-split group had more non-decannulated patients and a longer operative time. Conclusions: Thyroid-split tracheostomy is safe and feasible. Compared to the standard procedure, it provides better exposure and a similar rate of complications, although its de-cannulation success rate is lower.

Predicting Factors for a Favorable Pathologic Response to Neoadjuvant Therapy in Esophageal Cancer.

BACKGROUND: Favorable pathologic response(FPR) is a significant predictor for improved survival following Neoadjuvant therapy(NAT) in esophageal and gastroesophageal cancer(GEJ). Preoperative prediction of FPR could modify treatment plans. No reliable method for predicting FPR exists. We sought to identify preoperative predicting factors for FPR. MATERIALS AND METHODS: Retrospective analysis of patients with esophageal and GEJ cancer who underwent esophagectomy following (NAT). Univariate and multivariate analysis was used to identify preoperative predicting factors for FPR. A comparison of Tumor Regression Grade(TRG) was used to assess treatment response on overall survival(OS). RESULTS: Out of 121 patients, 82(67.8%) had neoadjuvant chemoradiation. FPR was observed in 60(49.6%). Female sex, Radiation therapy(RT), squamous cell carcinoma(SCC), lack of signet ring feature, and FDG avidity posttreatment were associated with FPR on univariate analysis. RT and SCC were associated with FPR (OR=3.9 and 4.0, respectively) on multivariate analysis. OS was lower among patients who did not achieve FPR to NAT(P=0.027). CONCLUSIONS: FPR is a predictor of improved OS. SCC and radiation therapy-based protocol were identified as major prediction factors of FPR in patients with esophageal and GEJ cancers.

Perspective and practice patterns of mediastinal staging among thoracic surgeons.

Background: Accurate mediastinal staging of lung cancer patients is critical for determining appropriate treatment. Mediastinoscopy and endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration are the most commonly utilized techniques. Limited data exist on training and practice trends among thoracic surgeons. We aimed to determine training and practice patterns and find whether there is a paradigm shift in mediastinal staging after the introduction of EBUS into practice among thoracic surgeons in the United States. Methods: 28-question survey was constructed querying demographic, training, and practice patterns with mediastinoscopy and EBUS and was sent to practicing thoracic surgeons in the United States. Descriptive statistics were used to summarize quantitative data. Results: Ninety-eight responded with a 93% completion rate. Eighty-seven percent of respondents received training in EBUS and 70% perform EBUS routinely. All respondents believe EBUS should be incorporated into thoracic surgery training curriculums. Majority of those who prefer EBUS feel EBUS is safer than mediastinoscopy, allows access to lymph nodes stations or lesions inaccessible by mediastinoscopy and prefer EBUS to avoid re-do mediastinoscopy and in irradiated mediastinum. Majority of those who prefer mediastinoscopy reported they perform more accurate staging compared to EBUS, that mediastinoscopy is more accurate in diagnosing lymphoma or sarcoidosis and that frozen section can be done at the same interval as resection. Among surgeons who prefer EBUS, 94% biopsy 3 or more lymph node stations, 86% routinely biopsy hilar (N1) nodes while 8% never biopsy N1 nodes. Of surgeons who prefer mediastinoscopy. Ninety-seven percent biopsy 3 or more lymph node stations, only 27% routinely biopsy N1 nodes and 70% never biopsy N1 nodes. Conclusions: EBUS is used frequently by thoracic surgeons in their practice for mediastinal staging. Methods of obtaining proficiency in EBUS widely varied among surgeons. In addition to mediastinoscopy, dedicated EBUS training should be incorporated into thoracic surgery training curriculums.

Thoracic surgery in Israel.

During the past 74 years since its establishment, Israel has evolved into a modernized country with well-established and effective public health care system. Thoracic surgeons in Israel play a central role in the diagnosis and treatment of patients with diseases of the chest wall, diaphragm, mediastinum, airways, Lung, and esophagus as well are taking part in designated trauma teams. Between 2,500-3,000 cases are being performed in 16 designated thoracic surgical units and departments across the country annually, the majority of them being performed in a minimally invasive fashion. Lung cancer is the leading cause of cancer related mortality in Israel and the second most common cancer in Israel. All types of thoracic oncologic cases are being presented routinely during designated multi-disciplinary conferences and treatment plans are designed according to the most up to date international guidelines. Each surgeon undergoes at least 6 years of formal training, followed by certifying exams. Advanced training is usually obtained overseas in centers of excellence. Israeli thoracic surgeons are part of an international societies and are actively involved in academic research. Despite the advancement of the Israeli health care system, thoracic surgeons in Israel are still facing few challenges that are limiting the early diagnosis of thoracic surgical malignancies such as lack of established national lung cancer screening program in Israel although a pilot program is being tested during these days. Tasked with taking care of diseases of the chest, and in order to remain at the forefront of diagnosis and treatment similar to our colleagues across the globe, Thoracic surgeons in Israel are continuously seeking to learn and evolve in order to improve and provide better care to our patients.

Combined pneumonectomy and esophagectomy for radiation-associated broncho-esophageal fistula.

Radiation therapy for broncho-pulmonary malignancies can lead to fistula formation between the digestive and respiratory tracts. Treatment options have been largely palliative in nature. Here, we report a combined pneumonectomy and esophagectomy, followed by staged retrosternal gastric pull-up esophageal reconstruction, for treatment of a broncho-esophageal fistula with good functional outcomes following reconstruction.

From Chest Wall Resection to Medical Management: The Continued Saga of Parapneumonic Effusion Management and Future Directions.

Pleural space infections have been described since the time of Hippocrates and to this day remains a significant pathology. Every year in the USA approximately there are one million hospital admissions for pneumonia with 20%-40% associated with some form of pleural space infections leading to pleural effusions with increased morbidity and mortality. Often, management of these effusions mandate combination of medical treatment and surgical drainage with debridement and decortication. There has been a lot of ongoing research regarding the safety and efficacy of intrapleural fibrinolytics in the management of complicated pleural effusions and empyema. Till this day, areas of debate and controversies exist among clinicians treating pleural space infection. Empyema is historically considered a surgical disease. There have been societies and guidelines for the management of infected parapneumonic effusions with antibiotics and chest tube drainage as an initial empiric treatment modality. With the advances in the use of Intrapleural fibrinolytics and minimally invasive procedures such as video-assisted thoracoscopic surgery (VATS), empyema a surgical disease is now more favoring medical management. Surgical option, such as open thoracotomy, is reserved for patients who failed conservative management and chronic empyema. The aim of this comprehensive review is to shed light on the evolution of various management strategies from the era of Hippocrates to current day practice and how there continues to be a paradigm shift in treating empyema as a surgical condition to a medical disease.

The impact of cervical anastomotic leak after esophagectomy on long-term survival of patients with esophageal cancer.

BACKGROUND: Anastomotic leak is a major complication after esophagectomy. There is a paucity of data on long-term oncological outcomes of cervical anastomotic leak after esophagectomy for cancer. We evaluated the impact of such a leak on postoperative outcomes as well as on long-term oncological outcomes. METHODS: A retrospective analysis of a prospectively maintained database of patients with esophageal cancer who underwent esophagectomy with a cervical esophagogastric anastomosis between 2010 and 2017. Patients were divided into 3 groups: patients with no anastomotic leak; patients with nonsevere (type 1 & 2) leak, and patients with severe (type 3) leak. A comparison of postoperative and long-term oncological outcomes was made between the groups. RESULTS: Two hundred and eight patients were included in this study. Thirty-two (15%) patients had cervical anastomotic leak, of which 20 (63%) had type 1 and 2 (nonsevere) leak, and 12 (37%) had type 3 (severe) leak. Overall, 30-day mortality rate was 7%. Mortality rate was 4% in patients without leak, 15% in patients with nonsevere leak, and 25% in patients with severe anastomotic leak (P = .007). Overall median survival was 42 months. Patients with severe leak had poorer overall survival compared to patients with nonsevere and no anastomotic leak (6, 38, and 39 months, respectively, P = .011). There was no difference in disease-free survival of patients with or without anastomotic leak. CONCLUSION: Leakage from cervical anastomosis after esophagectomy had no impact on disease-free survival of patients with esophageal cancer. Severe anastomotic leak was associated with lower overall survival, probably due to a high rate of postoperative mortality.

Outcomes of Barotrauma in Critically Ill COVID-19 Patients With Severe Pneumonia.

BACKGROUND: Pneumomediastinum and pneumothorax are complications which may be associated with barotrauma in mechanically ventilated patients. The current literature demonstrates unclear outcomes regarding barotrauma in critically ill patients with severe COVID-19. The purpose of this study was to examine the incidence of barotrauma in patients with severe COVID-19 pneumonia and its influence on survival. STUDY DESIGN AND METHODS: A retrospective cohort study was performed from March 18, 2020 to May 5, 2020, with follow-up through June 18, 2020, encompassing critically ill intubated patients admitted for COVID-19 pneumonia at an academic tertiary care hospital in Brooklyn, New York. Critically ill patients with pneumomediastinum, pneumothorax, or both (n = 75) were compared to those without evidence of barotrauma (n = 206). Clinical characteristics and short-term patient outcomes were analyzed. RESULTS: Barotrauma occurred in 75/281 (26.7%) of included patients. On multivariable analysis, factors associated with increased 30-day mortality were elevated age (HR 1.015 [95% CI 1.004-1.027], P = 0.006), barotrauma (1.417 [1.040-1.931], P = 0.027), and renal dysfunction (1.602 [1.055-2.432], P = 0.027). Protective factors were administration of remdesivir (0.479 [0.321-0.714], P < 0.001) and receipt of steroids (0.488 [0.370-0.643], P < 0.001). CONCLUSION: Barotrauma occurred at high rates in intubated critically ill patients with COVID-19 pneumonia and was found to be an independent risk factor for 30-day mortality.

History of esophagectomy for cancer of the esophagus and the gastroesophageal junction.

The introduction of anesthesia in 1846 created unseen opportunities for surgeons. By the end of the 19th century limited esophageal resection outside the chest had already been performed and the race for successful intrathoracic esophagectomy was on. The credit for the first successful esophagectomy for an intrathoracic cancer goes to Franz Torek of New York in 1913. But it was the introduction of double lumen intubation that really boosted the number of successful esophagectomies all over the world. In the second half of the 20th century progress in surgical techniques and perioperative management resulted in a substantial reduction of postoperative mortality. Introduction of multimodality therapies has further improved long term survival. The turn of the millennium saw the development of minimally invasive esophagectomy (MIE) improving postoperative quality of life. Undoubtly new technologies and newer drugs (e.g., immunotherapy) will further allow for refinements and more personalized targeted therapies. In this manuscript, the authors provide a deep dive into the history and development of esophageal surgery, with emphasis on the innovative pioneers that brought the field of esophageal surgery to the front line of surgery.
