The accuracy of clinical N staging of esophageal squamous cell carcinoma is suboptimal. As an important station of lymph node metastasis, station C201 (right recurrent laryngeal nerve nodes) has rarely been evaluated alone. We aimed to explore an effective way to evaluate the right recurrent laryngeal nerve nodes in thoracic esophageal squamous cell carcinoma.

We retrospectively analyzed 628 thoracic esophageal squamous cell carcinoma patients who underwent radical resection without neoadjuvant therapy from two Chinese cancer centers. The diameter of the short axis of the largest right recurrent laryngeal nerve node (DC201) was measured on contrast-enhanced multi-slice computed tomography (MSCT). Right recurrent laryngeal nerve nodes were examined by postoperative pathologic results. The receiver operating characteristic (ROC) curve was generated to assess the diagnostic capabilities of DC201 to determine the right recurrent laryngeal nerve nodes status.

ROC curve analysis revealed that the optimal cut-astasis, contrast-enhanced MSCT could evaluate the status of right recurrent laryngeal nerve nodes with high sensitivity and specificity. The largest right recurrent laryngeal nerve nodes were mainly located in the tracheoesophageal groove and/or above the suprasternal notch.

Trans-bronchoscope treatment for early stage small peripheral lung cancer, such as photodynamic therapy (PDT), has been investigated. However, despite the efficacy of PDT, light delivery issues limit its application. A method of administering mineral oil with a high refractive index (RI) was previously proposed to enhance light delivery in branched or bent anatomic structures. Lipiodol has a high RI and an exhaustive history of use as a contrast medium for bronchography. We aimed to determine whether the use of lipiodol, like mineral oil, could enhance the illumination effect and therapeutic range of PDT for peripheral lung tumors.

We injected lipiodol into a pig lung model, guided by a bronchoscope under fluorescent surveillance, to simulate future treatment in humans, and then illuminated with PDT laser fiber to the lipiodol-infused lung to test the technique feasibility in a pig orally administered 20 mg/kg of 5-aminolevulinicc acid (5-ALA) 2 hours before treatment. We also attempted to determine the mr PDT model. No severe lethal acute lung injury was caused by this PDT model under careful manipulation. Additional studies evaluating the dose correlation of the photosensitizer and light are needed.

Airway-gastric fistulas (AGFs) are rare but life-threatening complications after esophagectomy for esophageal cancer. Their effective and reasonable management is challenging and still controversial. selleck chemical This study reports the classification and management strategies of post-esophagectomy AGF based on a retrospective analysis of 26 cases in two large volume centers in China.

Between January 2000 and December 2017, 6,316 consecutive patients with esophageal carcinoma underwent esophagectomy. AGF was verified in 26 patients. The patients with AGF were divided into two types based on the anatomic characteristics of the fistula. Type I was characterized by the presence of fistula orifices in digestive tract that were higher than those in the airway and were treated with conservative management. Type II had both fistula orifices located on the same horizontal plane and were treated with surgical management. Pearson Chi-Square (R software) was used to compare mortality rates.

From January 2000 and December 2017, 26 cases occurred AGF in 6,316 consecutive patients with esophageal carcinoma underwent esophagectomy and the incidence of AGF was 0.4%. Ten of 12 patients with type I AGF survived. Nine of 14 patients with type II AGF died. There was a significantly difference in the mortality rates between patients with AGF type I and II, which was 16.7% (2/12) and 64.3% (9/14) (χ

=6.003, P=0.014), respectively.

AGF may be classified into two types according to the anatomic characteristics. Type I patients may be cured by conservative management and type II patients, require surgical intervention with pedicled tissues flap wrapping of the airway.

The standard adjuvant chemotherapy regimen for completely resected pathological stage II/IIIA non-small cell lung cancer (NSCLC) is four courses of cisplatin plus vinorelbine. However, the continuity and toxicity of cisplatin-based regimens remain problematic. Conversely, carboplatin-based chemotherapy is a less toxic and more tolerable regimen for various stages of NSCLC. In particular, the efficacy and tolerability of carboplatin plus S-1 in advanced NSCLC were confirmed by previous pivotal studies such as the LETS trail. Therefore, this phase II study assessed the feasibility, safety, and usefulness of carboplatin plus S-1 followed by maintenance S-1 as an adjuvant treatment.

In this single-arm, multicenter phase II study, 40 patients who previously underwent complete resection of NSCLC were enrolled from November 2013 to January 2015. The chemotherapy protocol was four cycles of carboplatin (AUC 5 on day 1) and oral S-1 (80 mg/m

every other day from days 1 to 21) followed by oral S-1 (80 mg/m

everse events were not severe. However, patients who can fully complete the regimen might experience clinical benefit.

Uniportal video-assisted thoracoscopic surgery (VATS) although considered less invasive than the multi-port techniques, is still an intercostal approach, resulting in intercostal nerve injury. Recently, some surgeons have tried to address this problem by attempting a subxiphoid approach. The aim of our study was to assess and compare results between intercostal and subxiphoid uniportal VATS lobectomy in terms of postoperative pain and quality of life (QoL).

Patients from January 2014 to January 2018 undergoing subxiphoid and intercostal VATS lobectomy were prospectively assessed for pain and QoL at 1, 3, and 6 months following discharge. Postoperative pain was measured using a numeric rating scale (NRS) and QoL was assessed with the EuroQoL 5-dimension questionnaire (EQ5D).

Eight hundred and thirty-three patients undergoing lobectomy were included 373 in the intercostal VATS group and 459 in the subxiphoid group. The proportion of patients with moderate or worse clinical pain was significantly lower at 1 and 3 months after subxiphoid VATS (P<0.01) compared with intercostal VATS. QoL was significantly higher following subxiphoid VATS at these same time points (P<0.001).

Uniportal subxiphoid VATS is a safe and feasible minimally invasive approach for undertaking pulmonary lobectomy that may result in reduced postoperative pain compared to conventional VATS. There may also be earlier return of QoL. A randomized controlled trial examining this further would provide further insight into our observations.

Prognosis in cardiac arrest (CA) patients has been challenging. We sought to investigate prognostic value combining serial disseminated intravascular coagulation (DIC) score and neuron-specific enolase (NSE) in out-of-hospital cardiac arrest (OHCA) patients.

Sixty-one consecutive patients successfully resuscitated after CA were included in the analysis. DIC score and NSE levels were serially analyzed after return of spontaneous circulation (ROSC). The outcome measure was death before hospital discharge. Prognostication performance was assessed as the area under the receiver-operating characteristics curve (AUC). Hosmer-Lemeshow test was used for internal validation of predictive models. Calibration curves were drawn to visualize the results of tests.

The NSE levels continued to increase in the first 72 h in non-survivors. In survivors, the NSE levels decreased after 48 h. Both DIC score at 48 h and NSE level at 48 h were good predictors of outcome. The AUC for predictive mortality in OHCA patients was 0.869 (95% CI, 0.781-0.956) for DIC score at 48 h combining NSE at 24 h, 0.878 (95% CI, 0.791-0.965) for DIC score at 48 h combining NSE at 48 h and 0.882 (95% CI, 0.792-0.972) for DIC score at 48 h combining NSE at 72 h, respectively. Significance of Hosmer-Lemeshow test was 0.488, 0.324, 0.011 for each combination.

Serial DIC score combined with measurement of NSE levels is a useful and accessible tool for prognostication following OHCA.

This study sought to evaluate the impact of a da Vinci Xi surgical robot on perioperative outcomes after pulmonary resections.

A retrospective analysis of prospectively collected STS data was performed at a single institution for patients who underwent elective lung resections from 2012 to 2019. Patient outcomes were compared at three different time periods before the adoption of the robot technology (predominately VATS), during the initial robot experience (the first 18 months), and after the mature robot experience (the second 18 months). Univariate and multivariate logistic regression modeling was performed to determine the factors associated with perioperative complications.

Five hundred and four patients underwent pulmonary resection between the three time periods 220 patients (43.7%) had surgery prior to the first use of the robot (predominately VATS), 126 patients (25%) had surgery during the initial experience with robot, and 158 patients (31.1%) had surgery during the mature robot experience. There were significantly less post-operative complications (15.2%

34.9%

39.1%, P<0.001), shorter median length of stay (2

3

4 days, P<0.001), and lower hospital readmission rates (1.9%

4%

11.8%, P<0.001) in the mature robot period compared to the initial robot period and the predominately VATS period, respectively. Multivariate analysis showed that the robot was associated with a decrease in post-operative complications (OR 0.36; 95% CI, 0.23-0.57, P<0.001).

The adoption of a da Vinci Xi robot in our institution was associated with improved outcomes in patients having pulmonary resections.

In the TNM system only the anatomic location is used to define nodal status. In this study we aim to evaluate the effectiveness of combining the location and ratio of metastatic lymph node (pN-NR) for the prognosis of non-small cell lung cancer (NSCLC).

Patients with pN1/pN2 NSCLC were retrieved from the SEER database. The optimal cut point of NR was determined with the maximal selecting test. All patients were divided into 4 categories with combination of pN (pN1 or pN2) and NR (low or high). The pN-NR was investigated as a predictor of overall survival (OS) and cause-specific survival (CSS) using Cox regression models. Survival curves were plotted using the Kaplan-Meier method and the difference was compared with log-rank test.

A total of 12,170 patients were enrolled. The optimal cut point of NR was 0.3. Patients were divided into 4 groups pN1-NR <0.3, pN1-NR ≥0.3, pN2-NR <0.3 and pN2-NR ≥0.3. The pN-NR was an independent prognostic factor for survival. Compared with pN1-NR <0.3, the hazard ratio of OS was 1.
