RESUMEN
Background: Combination of non-oncological pulmonary and cardiac conditions is common entity in modern thoracic surgery, allowing concurrent surgical correction. Multiple publications in the literature address the success of simultaneous interventions for combined conditions, however almost all are performed with an open approach. Case Description: A 49-year-old male with past medical history significant for bronchiectasis, complicated by fibrosis of the middle lobe, presented with dyspnea, recurrent hemoptysis, and nonproductive cough. Echocardiography revealed a large atrial septal defect (ASD), biventricular enlargement with severe mitral and tricuspid regurgitation. After multidisciplinary evaluation, patient was taken to the operating room for simultaneous cardiac intervention with right middle lobectomy. The total duration of surgery was 332 min, with cross-clamp time of 79 min. Estimated blood loss was 800 mL. Patient was extubated 3 h postoperatively, chest tube was removed on postoperative day 4 and the patient was discharged home on postoperative day 8 without postoperative complications. Conclusions: In this article, we describe the first case of simultaneous thoracoscopic uniportal intervention with cardiopulmonary bypass (CPB) in the treatment of multiple congenital heart defects and pulmonary complications of bronchiectasis. Presented case demonstrates potential advantage and feasibility of minimally invasive simultaneous procedures in patients with concurrent pulmonary and cardiac conditions. The described approach allowed radical surgical intervention to address both problems in the single setting, while retaining advantage of minimally invasive intervention.
RESUMEN
Objective: The current article describes modern endoscopic technologies that allow for advanced endoscopic tissue approximation and suturing. These technologies include such devices as through the scope and over the scope clips, endoscopic suturing OverStitch device and through the scope suturing X-Tack device. Background: Since the original introduction of the diagnostic endoscopy, progress in the field has been astonishing. Over the past several decades endoscopy has made numerous advancements allowing for a minimally invasive mechanism to treat life threatening conditions such as gastrointestinal (GI) bleeding, full thickness injuries, as well as chronic medical conditions such as morbid obesity and achalasia. Methods: A narrative review of all relevant and available literature on endoscopic tissue approximation devices over the last 15 years ago was conducted. Conclusions: Multiple new devices, including endoscopic clips and endoscopic suturing devices, have been developed for endoscopic tissue approximation that allow advanced endoscopic management of a wide variety of GI tract conditions. It is critical for practicing surgeons to actively participate in the development and use of these new technologies and devices in order to maintain leadership in the field, hone expertise, and to drive innovation. Further research in minimally invasive applications for these devices is needed as they continue to be refined. This article provides a general overview of the devices available and their clinical applications.
RESUMEN
Objective: The goal of this review is to describe and compare current and historic endoscopic interventions for gastroesophageal reflux disease (GERD). Background: The prevalence of GERD affects a large portion of the population. Nearly half of those treated with conservative medical therapy have refractory symptoms of reflux. Surgery is a durable solution for reflux, however, it is an invasive procedure and classical fundoplication comes with its own share of side effects and complications. In this review, we will discuss the advantages and pitfalls of available endoscopic procedures, and describe medium-term (up to several years) outcomes. Methods: Literature search of the PubMed database, including the years 1999 to 2021 was performed with search terms to reflect the described devices in the review. Individual review of retrieved references was performed for additional sources. Thorough review of societal guidelines was also conducted in preparation of this manuscript. Conclusions: Gastroesophageal reflux is a common problem in the United States and worldwide, and its prevalence continues to increase. Within the last two decades, there have been several new endoscopic modalities introduced for the management of this disease. Here, we present a focused review of endoscopic gastroesophageal reflux interventions, its advantages and pitfalls. Surgeons focusing on the foregut conditions should be aware of these procedures as they may provide a minimally invasive option for the selected group of patients.
RESUMEN
OBJECTIVE: To evaluate the adoption and clinical impact of endoscopic resection (ER) in early esophageal cancer. BACKGROUND: Staging for early esophageal cancer is largely inaccurate. Assessment of the impact of ER on staging accuracy is unknown, as is the implementation of ER. METHODS: We retrospectively reviewed 2608 patients captured in the Society of Thoracic Surgeons General Thoracic Surgery Database between 2015 and 2020. Patients with clinical T1 and T2 esophageal cancer without nodal involvement (N0) who were treated with upfront esophagectomy were included. Staging accuracy was assessed by clinical-pathologic concordance among patients staged with and without ER. We also sought to measure adherence to National Comprehensive Cancer Network staging guidelines for esophageal cancer staging, specifically the implementation of ER. RESULTS: For early esophageal cancer, computed tomography/positron emission tomography/endoscopic ultrasound (CT/PET/EUS) accurately predicts the pathologic tumor (T) stage 58.5% of the time. The addition of ER to staging was related to a decrease in upstaging from 17.6% to 10.8% ( P =0.01). Adherence to staging guidelines with CT/PET/EUS improved from 58.2% between 2012 and 2014 to 77.9% between 2015 and 2020. However, when ER was added as a staging criterion, adherence decreased to 23.3%. Increased volume of esophagectomies within an institution was associated with increased staging adherence with ER ( P =0.008). CONCLUSIONS: The use of CT/PET/EUS for the staging of early esophageal cancer is accurate in only 56.3% of patients. ER may increase staging accuracy as it is related to a decrease in upstaging. ER is poorly utilized in staging of early esophageal cancer. Barriers to the implementation of ER as a staging modality should be identified and corrected.

OBJECTIVE: Surgical repair of paraesophageal hernias in patients with hostile abdomen is challenging. Despite its utility as an open procedure, the adoption of the minimally invasive Belsey Mark IV procedure has been limited because of the complexity of using traditional video-assisted thoracoscopic instrumentation. The robotic platform offers additional degrees of freedom, which enables minimally invasive transthoracic approach despite challenging anatomy. The purpose of this article is to describe a technique of robotic approach for the Belsey Mark IV operation. METHODS: We retrospectively reviewed 5 cases of the robotic Belsey Mark IV procedure completed at a single institution between June 2018 and November 2021. Data were collected from a review of the medical records, including operative reports, anesthesia records, imaging, and clinical notes. The operative technique is described in the present article. There were 4 men and 1 woman. The average age of the patients was 64.4 ± 13.6 years, with an average body mass index of 24.5 kg/m2. Three patients had undergone previous transabdominal hiatal hernia repair, and 2 of them had 2 prior repairs. One patient underwent simultaneous pulmonary left lower lobectomy for cancer with the Belsey Mark IV procedure. RESULTS: The average operative time was 209 ± 95 min (110 to 360 min). The average postoperative length of stay was 4.2 days, and 2 patients experienced complications including bleeding and persistent air leak (after lobectomy). The average blood loss was 67 ± 25 mL. CONCLUSIONS: The robotic platform enables a transthoracic minimally invasive approach to the Belsey Mark IV operation.

Broncho-pleural fistula (BPF) is an abnormal communication between the bronchial lumen and the pleural space that typically occurs postoperatively. Surgical intervention is typically needed to patch the fistula; however, current literature lacks a gold standard for which treatment to use. With a high mortality rate, there is a clear urgency for quick and successful intervention. This case examines a 59-year-old patient presenting with a BPF 14 years after incidental pneumonectomy during upper lobectomy for invasive aspergillus. A fistula was appreciated during bronchoscopy with contrast injection. The fistula was closed via the transsternal approach through median sternotomy and pericardiotomy. This case report aims to provide a viable option to successfully repair a BPF via the transsternal approach.
RESUMEN
Background: Black esophagus is a relatively rare phenomenon that seems to occur in a morbid patient population, however, this entity may be more common than we currently know. Additionally, black esophagus may even be reversible in some cases. There are far fewer cases of black stomach described. The exact etiology and cause are less well known but may have similar risk factors as black esophagus. These disease pathologies are devastating to the patients they affect and can pose clinical challenges for the providers that encounter them. Case Description: This case report details our experience with a moribund patient who was found to have extensive pneumomediastinum and gastric perforation secondary to black esophagus and black stomach. This was diagnosed on endoscopy following imaging that showed extensive pneumomediastinum. Initially the intent was to temporize the disease process in an attempt to stabilize the patient however at the time of diagnosis, the degree of ischemia had led to perforation and the disease process was not reversible or recoverable. He ultimately expired after comfort directed care measures were put in place. Conclusions: To the best of our knowledge, this case will be the first reported in current literature and will hopefully shed some light on this unusual and devastating pathology.
RESUMEN
A 75-year-old male patient with a history of previous right lung transplant presented with left upper lobe squamous cell carcinoma. Endobronchial ultrasound and positron emission tomography displayed no mediastinal lymphadenopathy. A ventilation-perfusion scan displayed minimal perfusion to the native lung. Left robot-assisted lysis of adhesions, decortication, left upper lobectomy, and mediastinal lymphadenectomy were performed. The patient tolerated the procedure well. Final pathology displayed pT2a, n0, m0. Lobectomy is a safe and efficient treatment of native lung malignancy in the setting of previous lung transplant with minimally functioning native lung.

Bipolar esophageal exclusion is a "Hail Mary" procedure for control of leak and persistent mediastinal soilage from esophageal injury. Usually, the esophageal remnant scars down without negative consequences. Esophageal mucocele is a rare complication of bipolar esophageal exclusion. This is a case report of an iatrogenic esophageal transection and the subsequent treatment course. A retrospective chart review of the patient's medical and surgical history was performed. After a robotic hiatal hernia repair at an outside institution, the patient suffered an esophageal leak and was surgically treated with esophageal exclusion, wide drainage of the mediastinum, and decortication of the resulting empyema. She subsequently underwent retrosternal gastric conduit for esophageal reconstruction 4 months later. Three years after this, she developed a rare complication of esophageal exclusion, a symptomatic esophageal mucocele that required resection.

Salmonella is one of the most common Gram-negative pathogens and seriously threatens chicken farms and food safety. This study aimed to establish a multiplex polymerase chain reaction (PCR) approach for the identification of different Salmonella enterica subsp. enterica. The citE2 gene and interval sequence of SPS4_00301-SPS4_00311 existed in all S. enterica subsp. enterica serovars by genomic comparison. By contrast, a 76 bp deletion in citE2 was found only in Salmonella Pullorum. Two pairs of special primers designed from citE2 and interval sequence were used to establish the multiplex PCR system. The optimized multiplex PCR system could distinguish Salmonella Pullorum and non-Salmonella Pullorum. The sensitivity of the optimized multiplex PCR system could be as low as 6.25 pg/µL and 104 colony-forming units (CFU)/mL for genomic DNA and Salmonella Pullorum cells, respectively. The developed multiplex PCR assay distinguished Salmonella Pullorum from 33 different Salmonella enterica subsp. enterica serotypes and 13 non-target species. The detection of egg samples artificially contaminated with Salmonella Pullorum, Salmonella Enteritidis, and naturally contaminated 69 anal swab samples showed that results were consistent with the culture method. These features indicated that the developed multiplex PCR system had high sensitivity and specificity and could be used for the accurate detection of Salmonella Pullorum in clinical samples.

Tracheobronchoplasty (TBP) consists of splinting of the posterior membranous wall of the central airways with the goal of restoring a normal configuration and preventing excessive collapse in patients with tracheobronchomalacia (TBM). Despite some variation in technique, it consists of sewing a mesh on the posterior membranous wall of the trachea and both main stem bronchi. Traditionally performed through a right posterolateral thoracotomy, it should be reserved for cases of severe TBM. Surgical exposure necessitates dissection of the trachea from the thoracic inlet to the carina, as well the right main stem bronchus, bronchus intermedius and left main stem bronchus. Airway management in the operating room requires manipulation of the endotracheal tube (ETT) to allow safe placement of the sutures without puncturing the balloon. Other key technical considerations include downsizing of the airway with the mesh, and appropriate spacing of the sutures to ensure a plicating effect of the posterior membranous wall. More recently the robotic platform was used to perform TBP surgery. Its fine precise wristed motion and excellent visualization offer potential advantages over a thoracotomy and early outcomes of robotic-assisted TBP are encouraging. Longitudinal follow-up is still necessary to ensure the durability of repair in a patient population with significant underlying respiratory co-morbidities.
RESUMEN
Double lumen esophagus is an extremely rare condition, developing in most cases as a complication of antireflux procedures or gastroesophageal reflux itself secondary to the severe inflammatory process in and around the lower esophagus. We describe a case of iatrogenic double lumen esophagus after multiple previous Nissen fundoplications for chronic gastroesophageal reflux disease. There is no standard surgical intervention for the management of this complication. We present a first report of successful robot-assisted surgical reconstruction of a double lumen esophagus.

Objective: Diaphragm paralysis is a relatively uncommon entity that can be both congenital and acquired in nature. While commonly asymptomatic, it can also cause a significant decrease in pulmonary function and reserve, particularly in patients with underlying pulmonary diseases. Our aim was to summarize the current literature regarding the minimally invasive techniques used in the surgical correction of acquired diaphragm paralysis via traditional and robotic minimally invasive approaches. Methods: We conducted a systematic review of available literature using the Cochrane methodology and reported findings according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. Results: A total of 6,561 citations were identified through initial database and reference searches, of which 90 articles met the inclusion criteria for review. After further assessment, 33 appropriate full-text studies were selected for the review. Of the selected publications, the majority represented case reports and single-center retrospective studies with level of evidence 4. Only 1 level 2b study (individual cohort study) was identified, comparing minimally invasive and open approaches. Conclusions: Each of the minimally invasive approaches has its unique benefits and disadvantages, which are summarized and delineated in this article. Ultimately, no preferred method of diaphragm plication for diaphragm paralysis can be recommended at this time based on clinical data. The choice of procedure and surgical approach continues to be selected based on the surgeon's experience and preference.

Chest wall reconstruction presents a challenging surgical problem with no universally recognized gold standard for the procedure. Various prosthetic and bioprosthetic materials exist for use in chest wall reconstruction, with bioprosthetic materials offering significant advantages in the case of a preoperatively infected surgical field. Here we present a case of the absorbable BioBridge system (Acute Innovations, Hillsboro, OR) used for chest well reconstruction and describe a novel complication of structural failure of the BioBridge plate, involving fracturing of the prosthesis with wound erosion, ultimately requiring reoperation and removal of the device.

One of the new materials that have recently attracted wide attention of researchers are magnetoelectric (ME) composites. Great interest in these materials is due to their properties associated with the transformation of electric polarization/magnetization under the influence of external magnetic/electric fields and the possibility of their use to create new devices. In the proposed review, ME magnetic field sensors based on the widely used structures Terfenol-PZT/PMN-PT, Metglas-PZT/PMN-PT, and Metglas-Lithium niobate, among others, are considered as the first applications of the ME effect in technology. Estimates of the parameters of ME sensors are given, and comparative characteristics of magnetic field sensors are presented. Taking into account the high sensitivity of ME magnetic field sensors, comparable to superconducting quantum interference devices (SQUIDs), we discuss the areas of their application.
RESUMEN
Primary benign tumors of the sternum are an exceedingly rare entity. Surgical techniques regarding intervention for these lesions are not clearly defined in the literature given their scarcity. Operative techniques include en-bloc resection of the tumor, and this has proven to be successful in preventing local recurrence despite benign nature of the lesion. Given the often extensive defect created by the excision, reconstruction is frequently necessary; depending on the size of the defect, either autologous bone grafting or the use of synthetic materials may be indicated. This study serves to present two cases of rare primary benign tumors of the sternum, giant cell tumors and osteoma spongiosum and to summarize the available literature. We present a review of the literature of 17sternal giant cell tumor cases reported so far including our patient and unique case of osteoma spongiosum of the sternum, that discusses their surgical management, as well as reconstructive techniques that provided an excellent clinical result and a lack of recurrence on long term follow-up.
