    Background: Cervical anastomotic leakage (CAL) is one of the most common complications that occur minimally invasive esophagectomy (MIE). It is associated with high postoperative mortality. Some risk factors still remained controversial and so accurate prediction of risk groups for CAL remained very difficult. This study aimed to identify the risk factors of CAL after McKeown MIE to predict the accuracy of the technique as early as possible.

    Material and Methods: A total of 129 patients with esophageal cancer who underwent McKeown MIE at the Department of Thoracic Surgery, the Fourth Hospital of Hebei Medical University, between January 2018 and June 2019 were retrospectively reviewed. Multivariate logistic regression analysis was used to identify the risk factors for CAL and receiver operating characteristic (ROC) curve analysis was used to predict the accuracy for each quantitative data variable and determine the cutoff value.

    Results: There were statistically significant differences between Group CAL and Group NCAL in FEV1 (p = 0.031), neoadjuvant chemotherapy (p = 0.001), intraoperative minimum PaCO2 (p = 0.002), and hospital stays (p <0.001). In multivariate logistic regression, FEV1 (OR = 0.440, p = 0.047), neoadjuvant chemotherapy (OR = 4.425, p = 0.003), and intraoperative minimum PaCO2 (OR = 1.14, p <0.001) were identified to be three risk factors of CAL. The ROC curve analysis showed that FEV1 <2.18L (p = 0.029) and intraoperative minimum PaCO2 >45.5 mmHg (p = 0.002) demonstrated good accuracy.

    Conclusion: FEV1, neoadjuvant chemotherapy, and intraoperative minimum PaCO2 in arterial blood gas (ABG) were considered as risk factors of CAL after McKeown MIE for esophageal cancer. Preoperative FEV1 <2.18L and intraoperative minimum PaCO2 >45.5 mmHg in ABG showed good accuracy in predicting risk factors for CAL.

    Objective: The purpose of this study was to evaluate the predictive power of the platelet to albumin ratio (PAR) on survival outcomes of patients with non-small-cell lung cancer (NSCLC).

    Patients and Methods: In all, 198 patients with NSCLC were recruited. The X-tile software was performed to identify the optimal cutoff values for PAR, platelet to lymphocyte ratio (PLR), and neutrophil to lymphocyte ratio (NLR). The Kaplan–Meier method, univariate and multivariate analyses Cox regression were used to analyze the prognostic factors for overall survival (OS).

    Results: In all, 198 patients were enrolled, containing 146 (73.7%) men and 52 (26.3%) women. The optimal cutoff values for PAR, PLR, and NLR were 8.8×109, 147.7, and 3.9, respectively. Patients with PAR > 8.8 × 109 (P <0.001), PLR > 147.7 (P <0.001), and NLR >3.9 (P = 0.007) were associated with poor OS. Multivariate analyses found that PAR was an independent predictor in NSCLC patients (hazard ratio [HR]: 4.604, 95% confidence interval [CI]: 2.557–8.290, P <0.001).

    Conclusion: Preoperative PAR is a useful and potential prognostic biomarker in NSCLC patients who have received primary resection.

    Purpose: Single-port video-assisted thoracoscopic (VATS) pulmonary wedge resection was reported in 2004. We started using single-port VATS (SPVATS) pulmonary wedge resection in 2017 and compared results between conventional three-port VATS (VATS group) and SPVATS (SPVATS group).

    Methods: We identified 145 consecutive patients with VATS group and SPVATS group. Perioperative characteristics including pain and the number of stapler cartridges used were examined as the surgical outcomes, retrospectively.

    Results: In all, 66 cases of SPVATS group and 79 cases of VATS group pulmonary wedge resection were compared. The rate of epidural anesthesia (p <0.0001) was significantly higher and operative time (p <0.0001) was significantly longer with VATS group than with SPVATS group. The number of stapler cartridges used, duration of drain insertion, and rate of postoperative complications did not differ significantly between groups. Average numerical rating scale (NRS) score on postoperative day 1 and postoperative day 7 (p <0.0001 each), maximum NRS score on postoperative day 7 (p = 0.0082) and amount of 25 mg tramadol (p = 0.0062) were significantly lower in SPVAS group than in VATS group.

    Conclusion: Our results suggest that SPVATS pulmonary wedge resection offers better pain control and cost-effectiveness than three-port VATS pulmonary wedge resection. These findings should contribute to the body of evidence for SPVATS.

    Background: Extracorporeal membrane oxygenation (ECMO) as intraoperative cardiorespiratory support during lung transplantation is well known, but use for other types of surgery are limited. To assess risk factor for mortality after high-risk thoracic surgery and feasibility of ECMO, we reviewed.

    Methods: This study was an observational study. Between January 2011 and October 2018, 63 patients underwent thoracic surgery with ECMO for severe airway disease, pulmonary insufficiency requiring lung surgery, and other conditions.

    Results: In all, 46 patients remained alive at 30 days after surgery. The mean patient age was 50.38 ± 16.16 years. ECMO was most commonly used to prevent a lethal event (34 [73.9%]) in the Survival (S) group and rescue intervention (13 [76.5%]) in the Non-survival (N) group. In all, 11 patients experienced arrest during surgery (S vs N: 2 [4.3%] vs 9 [52.9%], p ≤0.001). The multivariate analysis revealed that arrest during surgery (odds ratio [OR], 24.44; 95% confidence interval [CI], 1.82–327.60; p = 0.016) and age (OR, 7.47; 95% CI, 1.17–47.85; p = 0.034) were independently associated with mortality.

    Conclusions: ECMO provides a safe environment during thoracic surgery, and its complication rate is acceptable except for extracorporeal cardiopulmonary resuscitation (ECPR).

    Objective: To explore the health-related quality of life (HRQoL) of children and adolescents with simple congenital heart defects before and after the transcatheter intervention.

    Methods: The Pediatric Quality of Life Inventory 4.0 scale was used to assess the quality of life of 78 children and adolescents before and after the transcatheter intervention and to evaluate the parents’ perception of their children’s quality of life.

    Results: In all, 76 patients were completed the study. The results showed that the scores of the four dimensions and the total score for the quality of life of the patients significantly improved 1 month after the intervention. At 6 months after treatment, the scores in all dimensions continued to improve. From the parents’ perspective, the scores of the patients in all dimensions improved significantly at 1 month and 6 months after treatment. In terms of the quality of life assessment, the self-assessment results of the patients were more positive than those of their parents.

    Conclusions: The results showed that the quality of life of children and adolescents with simple congenital heart defects can be positively affected by the transcatheter intervention. Moreover, this improvement is not transient and seems to increase over time.

    Objective: Our study aimed to evaluate short- and long-term outcomes of patients who required emergent conversion from transcatheter aortic valve implantation (TAVI) to open surgery. Besides, the reasons and procedural settings of emergent cardiac surgery (ECS) were also reported.

    Methods: We retrospectively reviewed the patients who underwent TAVI in our institution between 2012 and 2019 and collected the clinical data of cases who converted from TAVI to bail-out surgery. Telephone and outpatient follow-ups were performed.

    Results: Of 516 TAVI patients, 20 required ECS, and the bail-out surgery occurred less frequently with the increase in TAVI volume. The most common reason for conversion was left ventricular perforation (7/20, 35.0%). Thirty-day mortality was 35.0% in ECS patients. Kaplan–Meier survival curves showed that the cumulative survival rate was 65.0% at 1 year, 50.1% at 5 years in all ECS patients, and 77.1% at 5 years in patients who survived over 30 days after conversion.

    Conclusion: Although the bail-out operation was performed immediately after TAVI abortion, ECS still associated with high 30-day mortality. The long-term survival benefit was seen in patients surviving from bail-out surgery. An experienced TAVI team is of crucial importance in avoiding ECS-related life-threatening complications and providing effective salvage surgery.

    Objectives: Several factors determining differences between types A and B aortic dissection (AD) have been reported; however, little data exist examining their differences in left ventricular hypertrophy (LVH). We compared the prevalence of LVH in patients with types A and B AD.

    Methods: We retrospectively analyzed 334 patients with acute AD (227 type A; 107 type B). Concentric hypertrophy (CH; increased left ventricular mass index [LVMI] and relative wall thickness [RWT]) is one of four types of left ventricular (LV) geometry thought to be most associated with hypertension. We compared LVMI and the prevalence of CH in patients with types A or B AD. Multivariate logistic regression analyses of variables associated with type B AD were performed.

    Results: Comparing type A and B AD, LVMI (95 ± 26 vs.107 ± 28, p <0.001) and prevalence of CH (26% vs. 44%, p = 0.001) were higher in type B AD. In multivariate analysis, CH was an independent factor associated with type B AD (odds ratio: 2.62, confidence interval: 1.54–4.47, p <0.001).

    Conclusions: Our data suggested LVH was more prevalent in type B than in type A AD. Considering LVH usually results from hypertension, patients with type B AD may be more affected by hypertension than those with type A.
