BACKGROUND
Esophageal malignancies have a high morbidity rate worldwide, and minimally invasive surgery has emerged as the primary approach for treating esophageal cancer. In recent years, there has been increasing discussion about the potential of employing inflatable mediastinoscopic and laparoscopic approaches as an option for esophagectomy. Building on the primary modification of the inflatable mediastinoscopic technique, we introduced a secondary modification to further minimize surgical trauma.
METHODS
We conducted a retrospective analysis of patients who underwent inflatable mediastinoscopy combined with laparoscopic esophagectomy at the Second Affiliated Hospital of Naval Medical University from March 2020 to March 2023. The patients were allocated to the following two groups: the traditional (primary modification) group, and the secondary modification group. Operation times, intraoperative bleeding, and postoperative complications were compared between the groups.
RESULTS
The procedure was successfully performed in all patients, and conversion to open surgery was not required in any case. There were no statistically significant differences in the surgical operation time, intraoperative bleeding, number of dissected lymph nodes, and rate of postoperative anastomotic leakage between the two groups. However, a statistically significant difference was observed in the length of the mobilized esophagus between the two groups. The mobilization of esophagus to the level of diaphragmatic hiatus via the cervical incision was successfully achieved in more patients in the secondary modification group than the primary modification group.
CONCLUSIONS
Inflatable mediastinoscopy combined with single-incision plus one-port laparoscopic esophagectomy is a safe and effective surgical procedure. The use of a 5-mm flexible endoscope, ultra-long five-leaf forceps, and LigaSure Maryland forceps facilitates esophageal mobilization and lymph node dissection through a single cervical incision.

Veterinary Surgery : VS Apr 2024To report technical feasibility and describe procedural details of a novel single incision minimally invasive approach to the mediastinum in cadaver dogs.
OBJECTIVE
To report technical feasibility and describe procedural details of a novel single incision minimally invasive approach to the mediastinum in cadaver dogs.
STUDY DESIGN
Cadaveric study.
ANIMALS
Large breed (25-40 kg) cadaver dogs (n = 10).
METHODS
Three of 10 cadavers were used for preliminary technique development without data recording. Cadaver specimens underwent pre- and postoperative thoracic computed tomographic scans. Seven dogs were placed in dorsal recumbency and mediastinoscopy was performed via a SILS port placed cranial to the thoracic inlet with CO insufflation of the mediastinum at 2-4 mmHg. Retrieval of all CT and visually identified mediastinal lymph nodes (LN) was attempted; endoscopic compartmental and individual LN dissection times and subjective operative challenges were recorded. Procedural success scores for visualization and dissection as well as NASA-task force index scores were recorded per lymph node, per cadaver.
RESULTS
Median time required for initial approach including SILS placement was 5 min (range 5-10 min). Individual LN retrieval times ranged from 2 to 32 min. Mediastinoscopic retrieval of LNs was most commonly successful for the left tracheobronchial LN (7/7), followed by the right tracheobronchial LN (4/7), the left and right sternal LNs (3/7 each), and the cranial mediastinal LNs (1/7). Post-procedure pleural gas was identified on CT in 4/7 cadavers.
CONCLUSIONS
Mediastinoscopy as reported was feasible in large breed canine cadavers and retrieval or cup biopsy of a variety of lymph nodes is possible from the described approach. Application in living animals and its associated challenges should be further investigated.
CLINICAL SIGNIFICANCE
Mediastinoscopy may provide a novel minimally invasive approach to the evaluation and oncologic staging of the cranial mediastinum in dogs.

Comparative Study
BACKGROUND
The McKeown minimally invasive esophagectomy (McMIE) procedure has various limitations, including surgical contraindications and a high rate of postoperative pulmonary complications. A novel mediastinoscopic esophagectomy procedure was described in this study by using esophageal invagination and a transhiatal and bilateral cervical approach (EITHBC).
METHODS
According to the mode of operation, a total of 259 patients were divided into two groups, among which 106 underwent EITHBC and 153 underwent McMIE. The number of lymph nodes dissected, intraoperative outcomes, and postoperative outcomes were compared between the two groups of patients.
RESULTS
The results revealed that the average number of resected lymph node in the EITHBC group was significantly higher in the recL106 and TbL106 stations (recL106: 1.75 vs. 1.51, p = 0.016, TbL106: 1.53 vs. 1.19, p = 0.016) and significantly lower in the 107 stations (1. 74 vs. 2. 07, p < 0.001) than in the McMIE group. The intraoperative blood loss in the EITHBC group was significantly lower than that in the McMIE group (63.30 vs. 80.45 mL, p < 0.001). The incidence of postoperative pulmonary complications in the EITHBC group was lower than that in the McMIE group (14.15% vs. 27.45%, p = 0.008). The incidence of recurrent laryngeal nerve paralysis in the EITHBC group was significantly higher than that in the McMIE group (26.41% vs. 10.46%, p = 0.003).
CONCLUSION
Compared with the McMIE procedure, the EITHBC procedure has advantages in terms of removing the upper mediastinal lymph nodes and reducing postoperative pulmonary complications.

BACKGROUND
Mediastinoscopic surgery for esophageal cancer facilitates early postoperative recovery. However, it can occasionally cause serious complications. Here, we present the case of a patient with a tracheal injury diagnosed by a sudden increase in end-tidal carbon dioxide (EtCO) during mediastinoscopic subtotal esophagectomy.
CASE PRESENTATION
A 52-year-old man diagnosed with esophageal cancer was scheduled to undergo mediastinoscopic subtotal esophagectomy. During the mediastinoscopic procedure, the EtCO level suddenly increased above 200 mmHg, and the blood pressure dropped below 80 mmHg. We immediately asked the operator to stop insufflation and found a tracheal injury on the right side of the trachea near the carina by bronchoscopy. The endotracheal tube was replaced with a double-lumen tube, and the trachea was repaired via right thoracotomy. There were no further intraoperative complications. After surgery, the patient was extubated and admitted to the intensive care unit.
CONCLUSIONS
Monitoring EtCO levels and close communication with the operator is important for safely managing sudden tracheal injury during mediastinoscopic esophagectomy.

BACKGROUND
Thoracic esophageal cancer resection through the neck approach has recently been reported as mediastinoscopic surgery. We present the first report of a new minimally invasive technique for thoracic esophageal cancer: robot-assisted transcervical esophagectomy with a bilateral cervical approach.
METHODS
Ten cases of robot-assisted bilateral transcervical esophagectomy performed at the National Cancer Center Hospital East, Japan, from February 2023 to August 2023 were reviewed. The short-term surgical outcomes were presented, and the feasibility and efficacy of this procedure were discussed.
RESULTS
The mean operation time for the cervical procedure was 184.2 ± 23.6 min. The total time for the whole procedure was 472.7 ± 28.4 min, and total intraoperative blood loss was 162.2 ± 40.0 ml. Among the 10 cases, one patient developed recurrent nerve paralysis, one patient developed pulmonary complications, and no patients developed postoperative pneumonia. The median postoperative hospital stay was 22 (range: 12-43) days. No patients developed severe postoperative surgical complications, which were graded as Clavien-Dindo ≥ III. The total number of surgically harvested mediastinal lymph nodes was 37.2 ± 11.2.
CONCLUSIONS
Robot-assisted bilateral transcervical esophagectomy, a novel procedure for thoracic esophageal cancer, was safe and feasible. Using this procedure, the incidence of recurrent nerve palsy, which is a problem with transcervical esophagectomy and mediastinoscopic esophagectomy, is expected to decrease.

OBJECTIVES
The aim of this study is to analyze the accuracy of video-assisted mediastinoscopic lymphadenectomy (VAMLA) and the unsuspected (u) N2/3 rates in patients with non-small cell lung cancer (NSCLC) and normal mediastinum by integrated positron emission tomography-computed tomography.
METHODS
Prospective observational single-center study of 603 consecutive VAMLAs from 2010 to 2022.
EXCLUSION CRITERIA
other indications (n = 32), tumors different from NSCLC (n = 91), and clinical (c) N2/3 tumors by positron emission tomography-computed tomography (n = 46). Systematic nodal dissection was the gold standard to validate negative VAMLAs. Those patients with negative VAMLA and missing reference standard test were excluded. uN2/3 rates were analyzed in the global series and in the subgroups of tumors according to their clinical nodal and tumor categories. Pathologic findings were reviewed, and staging values were calculated.
RESULTS
Three hundred eighty-three patients with cN0/1 NSCLC underwent VAMLA. Staging values of VAMLA were: sensitivity, 0.98 (95% CI, 0.92-0.99); negative predictive value, 0.99 (95% CI, 0.98-1); and diagnostic accuracy, 0.99 (95% CI, 0.98-1). The uN2/3 rate for the whole series (N = 383) was 18.8%. The uN2/3 rates according to presurgical nodal and tumor categories determined by positron emission tomography computed tomography were: 3.6% (4 out of 111) in cT1N0; 16.3% (18 out of 110) in cT2N0; 10.25% (4 out of 39) in cT3N0; and 32% (7 out of 22) in cT4N0. Forty-two percent (39 out of 93) in cN1; complication rate was 7%.
CONCLUSIONS
This series of NSCLC with normal mediastinum staged by VAMLA demonstrates a high accuracy of this technique and a high rate of uN2/3 disease (specially in cN1 and cT4N0). VAMLA could be considered the reference staging procedure for staging cN0/1 NSCLC.

Review
Surgery is a crucial treatment option for patients with resectable esophageal cancer. The emergence of minimally invasive esophageal techniques has led to the popularity of video-assisted thoracoscopic esophagectomy, which has proven to be more advantageous than traditional thoracotomy. However, some patients with esophageal cancer may not benefit from this procedure. Individualized treatment plans may be necessary for patients with varying conditions and tolerances to anesthesia, making conventional surgical methods unsuitable. Inflatable video-assisted mediastinoscopic transhiatal esophagectomy (IVMTE) has emerged as a promising treatment option for esophageal cancer because it does not require one-lung ventilation, reduces postoperative complications, and expands surgical indications. This technique also provides surgical opportunities for patients with impaired pulmonary function or thoracic lesions. It is crucial to have a comprehensive understanding of the advancements and limitations of IVMTE to tailor treatment plans and improve outcomes in patients with esophageal cancer. Understanding the advantages and limitations of this surgical method will help specific patients with esophageal cancer. We conducted a thorough review of the relevant literature to examine the importance of IVMTE for individualized treatment of this disease.

BACKGROUND AND OBJECTIVE
To evaluate the diagnostic accuracy and clinical usefulness of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for mediastinal staging of centrally located T1N0M0 non-small cell lung cancer (NSCLC) clinically staged with positron emission tomography/computed tomography (PET/CT).
METHODS
We conducted a study that included patients with centrally located T1N0M0 NSCLC, clinically staged with PET/CT who underwent EBUS-TBNA for mediastinal staging. Patients with negative EBUS-TBNA underwent mediastinoscopy, video-assisted mediastinoscopic lymphadenectomy (VAMLA) and/or lung resection with systematic nodal dissection, that were considered the gold standard. The sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), overall accuracy of EBUS-TBNA for diagnosing mediastinal metastases (N2 disease) and the number needed to treat (NNT: number of patients needed to undergo EBUS-TBNA to avoid a case of pathologic N2 disease after resection) were calculated.
RESULTS
One-hundred eighteen patients were included. EBUS-TBNA proved N2 disease in four patients. In the remaining 114 patients who underwent mediastinoscopy, VAMLA and/or resection there were two cases of N2 (N2 prevalence 5.1%). The sensitivity, specificity, NPV, PPV and overall accuracy for diagnosing mediastinal metastases (N2 disease) were of 66%, 100%, 98%, 100% and 98%, respectively. The NNT was 31 (95% CI: 15-119).
CONCLUSION
EBUS-TBNA in patients with central clinically staged T1N0M0 NSCLC presents a good diagnostic accuracy for mediastinal staging, even in a population with low prevalence of N2 disease. Therefore, its indication should be considered in the management of even these early lung cancers.

BACKGROUND
Mediastinoscope-assisted transhiatal esophagectomy (MATHE) is the most minimally invasive esophagectomy procedure. It is a more challenging procedure and more difficult to be popularized than thoracoscopic surgery. We developed a new MATHE operation mode that provides a clearer visual field and makes the procedures simpler.
METHODS
A total of 80 patients with esophageal cancer were divided into a control group (n = 29) and a study group (n = 51). The control group underwent classic MATHE, while the study group received modified MATHE. We compared the two groups on operation time; intraoperative blood loss; blood transfusion amount; incidence rate of lung infection, recurrent laryngeal nerves (RLNs) injury, chylothorax, and anastomotic leakage; and upper mediastinal lymph node dissection.
RESULTS
The study group was significantly better than the control group in operation time (271.78 min vs. 322.90 min, p < 0.05), intraoperative blood loss (48.63 mL vs. 68.97 mL, p < 0.05), and left paratracheal lymph node (No. 4L) dissection rate (88.24% vs. 24.14%, p < 0.01). No significant differences were identified in the incidence rate of anastomotic leakage, lung complications, or RLNs injury between the two groups.
CONCLUSION
The modified MATHE is easier to perform. Modified MATHE is significantly superior to classic MATHE in operation time, intraoperative blood loss, and upper mediastinal lymph node dissection rate.
