UNASSIGNED: Thoracoscopic surgery is a primary treatment for lung cancer, with lobectomy and mediastinal lymph node dissection being the predominant surgical approaches for invasive lung cancer. While many thoracic surgeons can proficiently perform lobectomy, thorough and standardized lymph node dissection remains challenging. This study aimed to explore a safer and more efficient surgical method for mediastinal lymph node dissection in lung cancer.
UNASSIGNED: A prospective randomized controlled study was conducted, involving 100 patients with right lung cancer who were admitted to our hospital from January 2021 to April 2024 and met the inclusion criteria. These patients were randomly divided into an observation group (tissue pneumoperitoneum technique around lymph nodes group) and a control group (conventional surgery group). Thoracoscopic lobectomy and mediastinal lymph node dissection were performed. Intraoperative and postoperative related indicators were observed to validate the effectiveness and safety of the tissue pneumoperitoneum technique around lymph nodes.
UNASSIGNED: The observation group showed a significantly shorter lymph node dissection surgery time compared to the control group, with a statistically significant difference (p < 0.05). The number of lymph nodes dissected in the observation group was significantly higher than that in the control group, with a statistically significant difference (p < 0.05). Although the observation group had slightly more mediastinal lymph node stations dissected than the control group, the difference was not statistically significant (p > 0.05). The total drainage volume within three days postoperatively was comparable between the two groups, with no statistically significant difference (p > 0.05). The observation group had shorter chest tube indwelling time and postoperative hospital stay than the control group, with statistically significant differences (p < 0.05). The incidence of surgical complications was similar between the two groups, and there were no perioperative deaths.
UNASSIGNED: The tissue pneumoperitoneum technique around lymph nodes is a more efficient method for mediastinal lymph node dissection in lung cancer, demonstrating safety and feasibility, and is worthy of promotion.

To evaluate the efficacy and postoperative complications of endoscopic thoracoscopic and laparoscopic radical esophagectomy compared to open surgery in esophageal cancer treatment. This retrospective study included 103 esophageal cancer patients admitted from August 2018 to March 2022, divided into observation (endoscopic surgery) and control (open surgery) groups. We compared intraoperative parameters, postoperative outcomes, immune function, and one-year overall survival (OS). Intraoperative bleeding volume, the retention time of chest tube, postoperative fasting time, and hospital stay in the observation group were smaller than those in the control group (P < .05). The differences were not statistically significant (P > .05) when comparing operative time, the number of intraoperative blood transfusion cases, and the rate of operating room extubation in these 2 groups. The differences were not statistically significant when comparing the amount of resected lymph nodes and the positive rate of incisal edge in these 2 groups (P > .05). There was no statistically significant difference in the complication rates such as pneumonia, pleural effusion, pneumothorax, pulmonary embolism, anastomotic fistula, the leakage of thoracic duct, the injury of RLN and arrhythmia in these 2 groups (P > .05). At 7 days postoperatively, the CD4+ and CD4+/CD8+ in the observation group and the control group were smaller than the preoperative ones in their same groups, and they were larger in the observation group than those in the control group (P < .05); There was no statistically significant difference on the CD8+ in the observation group and the control group at 7 days postoperatively compared with the preoperative ones in their same groups (P > .05). The 1-year postoperative OS rate was 81.63% (40/49) in the observation group and 72.22% (39/54) in the control group, and the difference was not statistically significant when comparing the OS rates of these 2 groups (P = .238, HR = 0.622, 95% CI = 0.279-1.385). Endoscopic thoracoscopic and laparoscopic esophagectomy offers less invasive treatment with significant short-term benefits and better preservation of immune function in esophageal cancer patients, making it a safe and effective surgical option.

BACKGROUND: This study aims to present a novel surgical approach for the resection of anterior mediastinal tumors, specifically focusing on micronodular thymoma with lymphoid stroma (MNT), a rare and distinct variant of thymoma. The single subxiphoid incision technique, although reported in limited cases, offers a minimally invasive option with potential benefits. We report the case of a 76-year-old male who underwent this innovative procedure and was diagnosed with MNT, providing insight into the management and outcomes of this rare pathology.
METHODS: The patient presented for the excision of an anterior mediastinal tumor, with the surgery facilitated by sternal hooks to improve visualization. The rarity of MNT and its unclear prognosis underscore the need for enhanced diagnostic accuracy and tailored treatment strategies.
METHODS: Initially diagnosed preoperatively with a thymic cyst, the patient\'s final diagnosis was revised to MNT following surgery, highlighting the diagnostic challenges associated with this rare tumor.
METHODS: The tumor was successfully removed using minimally invasive thoracoscopic surgery through a subxiphoid single-incision, demonstrating the feasibility and potential advantages of this approach.
RESULTS: The patient had a favorable postoperative course, with a swift recovery and no complications, and remained in good health without signs of relapse at the 9-month follow-up.
CONCLUSIONS: This case underscores the importance of recognizing the unique pathological features of MNT and the need for a cautious diagnostic approach to differentiate it from other cystic lesions. Additionally, the successful use of single-port thoracoscopy under the xiphoid process for the removal of thymic tumors suggests its potential as an effective surgical method for these challenging cases.

BACKGROUND: Postoperative time to extubation plays a role in prognosis after heart valve surgery; however, its exact impact has not been clarified. This study compared the postoperative outcomes of minimally invasive surgery and conventional sternotomy, focusing on early extubation and factors influencing prolonged mechanical ventilation.
METHODS: Data from 744 patients who underwent heart valve surgery at the Zhejiang Provincial People\'s Hospital between August 2019 and June 2022 were retrospectively analyzed. The outcomes in patients who underwent conventional median sternotomy (MS) and minimally invasive (MI) video-assisted thoracoscopic surgery were compared using inverse probability of treatment weighting (IPTW) and Kaplan-Meier curves. Clinical data, including surgical data, postoperative cardiac function, postoperative complications, and intensive care monitoring data, were analyzed.
RESULTS: After propensity score matching and IPTW, 196 cases of conventional MS were compared with 196 cases of MI video-assisted thoracoscopic surgery. Compared to patients in the conventional MS group, those in the MI video-assisted thoracoscopic surgery group in the matched cohort had a higher early postoperative extubation rate (P < 0.01), reduced incidence of postoperative pleural effusion (P < 0.05), significantly shorter length of stay in the intensive care unit (P < 0.01), shorter overall length of hospital stay (P < 0.01), and lower total cost of hospitalization (P < 0.01).
CONCLUSIONS: Successful early tracheal extubation is important for the intensive care management of patients after heart valve surgery. The advantages of MI video-assisted thoracoscopic surgery over conventional MS include significant reductions in the duration of use of mechanical ventilation support, reduced length of intensive care unit stay, reduced total length of hospitalization, and a favorable patient recovery rate.

BACKGROUND: Thoracoscopic-guided thoracic paravertebral nerve block (TG-TPVB) and thoracoscopic-guided intercostal nerve block (TG-INB) are two postoperative analgesia technology for thoracic surgery. This study aims to compared the analgesic effect of TG-TPVB and TG-INB after uniportal video-asssited thoracic surgery (UniVATS).
METHODS: Fifty-eight patients were randomly allocated to the TG-TPVB group and the TG-INB group. The surgical time of nerve block, the visual analog scale (VAS) scores, the consumption of sufentanil and the number of patient-controlled intravenous analgesic (PCIA) presses within 24 h after surgery, the incidence of adverse reactions were compared between the two groups.
RESULTS: The VAS scores were significantly lower during rest and coughing at 2, 6, 12, and 24 h in the TG-TPVB group than in the TG-INB group (P < 0.05). The consumption of sufentanil and the number of PCIA presses within 24 h after surgery were significantly lower in the TG-TPVB group than in the TG-INB group (P < 0.001).The surgical time of nerve block was significantly shorter in the TG-TPVB group than in the TG-INB group (P < 0.001). The incidence of bleeding at the puncture point was lower in the TG-TPVB group than that in the TG-INB group (P < 0.05).
CONCLUSIONS: TG-TPVB demonstrated superior acute pain relieve after uniVATS, shorter surgical time and non-inferior adverse effects than TG-INB.

BACKGROUND: The purpose of this retrospective study was to compare the safety and feasibility of single-intercostal totally minimally invasive Ivor Lewis esophagectomy (MIIE) with those of multiple-intercostal MIIE.
METHODS: Between January 2016 and December 2022, clinical data were collected for 528 patients who successfully underwent totally minimally invasive esophagectomy. Among these patients, 294 underwent MIIE, with 200 undergoing the single-intercostal approach and 94 undergoing the multiple-intercostal approach. Propensity score matching (PSM) was applied to the cohort of 294 patients. Subsequently, perioperative outcomes and other pertinent clinical data were analyzed retrospectively.
RESULTS: A total of 294 patients were subjected to PSM, and 89 groups of patient data (178 persons in total) were well balanced and included in the follow-up statistics. Compared to the multiple intercostal group, the single intercostal group had a shorter operative time (280 min vs. 310 min; p < 0.05). Moreover, there was no significant difference in the incidence of major perioperative complications (p > 0.05). The total number of lymph nodes sampled (25.30 vs. 27.55, p > 0.05) and recurrent laryngeal nerve lymph nodes sampled on the both sides (p > 0.05) did not significantly differ. The single intercostal group had lower postoperative long-term usage of morphine (0,0-60 vs. 20,20-130; p < 0.01), total temporary addition (10,0-30 vs. 20,20-40; p < 0.01) and temporary usage in the first 3 days after surgery (0,0-15 vs. 10,10-20; p < 0.01) than did the multicostal group.There were no significant differences in age, sex, tumor location or extent of lymphadenectomy or in the clinical factors between the single-intercostal group (p > 0.05).
CONCLUSIONS: Both techniques can be used for the treatment of esophageal cancer. Compared to multiple intercostal MIIE, the feasibility of which has been proven internationally, the single intercostal technique can also be applied to patients of different age groups and sexes and with different tumor locations. It can provide surgeons with an additional surgical option.

OBJECTIVE: Thoracoscopy has gained extensive utilization in managing pleural disorders, and enhanced recovery after surgery (ERAS) can improve patients\' prognosis and expedite post-surgical recovery. This study aimed to investigate the knowledge, attitudes, and practices (KAP) towards ERAS among patients underwent thoracoscopy surgery.
METHODS: This cross-sectional study was conducted between September 2022 and August 2023, among patients underwent thoracoscopy surgery in 6 Secondary or Tertiary hospitals in the author\'s area. Demographic characteristics and KAP scores were collected by questionnaires, and clinical data were extracted from medical records.
RESULTS: A total of 309 valid questionnaires were collected, with 165 (53.40%) males and 202 (65.37%) aged ≤65 years old. The mean scores for KAP were 28.92±7.21 (possible range: 9-45), 53.60±6.73 (possible range: 13-65), and 43.45±5.50 (possible range: 10-50), respectively. SEM confirmed the positive associations between knowledge and attitude (β = 0.108, P = 0.019), knowledge and practice (β = 0.096, P = 0.004), and attitude and practice (β = 0.438, P<0.001). However, the KAP were found not associated with prognosis.
CONCLUSIONS: Patients underwent thoracoscopy surgery showed moderate knowledge, positive attitude, and appropriate practice towards ERAS. Preoperative education, personalized counseling, peer support groups, peer support groups, and follow-up care were recommended in further clinical practice.

Implications of repeated resections of pulmonary metastasis (PM) are not well documented in the modern era. Fifteen children underwent two (n = 8), three (n = 3), or four or more (n = 3) resections (total = 38 procedures), most commonly for osteosarcoma (71%). Operative approach included muscle-sparing thoracotomy (71%), non-muscle-sparing thoracotomy (18%), and video-assisted thoracoscopy (11%). Median resected nodules per procedure was four (range = 1-95). Prolonged air leaks were the most common postoperative complication (29%). Median hospital stay was 4 days, and no children were discharged with or have required oxygen. Event-free survival is 67% at median follow-up time of 54 months, with an overall survival rate of 64%. Repeat resection of PM appears to be well tolerated, without prolonged hospital stays or compromised pulmonary function.

BACKGROUND: Myasthenia gravis is an autoimmune disease with high prevalence of thymus disorders, in which, thymectomy is considered one of the therapeutic approaches in improving the patients\' clinical outcomes. Today, thoracoscopic thymectomy has received significant attention than the classic transsternal approach due to fewer complication. Therefore, this study was designed with the aim of investigating the therapeutic outcomes of thymectomy in patients with myasthenia gravis in the Afzalipour Hospital of Kerman between 2011 and 2021.
METHODS: The current study is a descriptive analytical study on patients with myasthenia gravis who underwent surgical thymectomy within 2011-2021. Demographic and clinical characteristics of patients from the time of operation to three years of follow-up were extracted and recorded from clinical records or by phone calls. Data were analyzed using SPSS software.
RESULTS: The data of 70 patients who underwent surgical thymectomy were analyzed. Thymectomy caused a significant reduction in the severity of the disease according to the Osserman classification (P = 0.001). It also significantly reduced the use of corticosteroids (P = 0.001) and IVIG (P = 0.015) compared to the time before the surgery. Sixty-two patients (88.57%) needed to take less medicine than before surgery. Left VATS was associated with less post-operative severity of the disease (P = 0.023). There were only two deaths during the follow-up period.
CONCLUSIONS: Overall, the findings of the present study demonstrated that thoracoscopic thymectomy is a useful surgical approach that leads to faster recovery, reducing the severity of the disease, need for medication, and complications in patients with myasthenia gravis, In comparison with the transsternal approach.

BACKGROUND: The aim was to evaluate short- and long-term outcomes for thoracoscopic repair of EA/TEF and compare with open repair.
METHODS: Patients who underwent EA/TEF repair during 2000-2020 were evaluated retrospectively. Patients with delayed repair were excluded. Demographic, operative, outcome data was collected. Outcomes were compared using Wilcoxon-rank sum tests for continuous, Chi-squared/Fisher\'s exact tests for categorical data.
RESULTS: There were 104 patients with primary repair, 49 (47.1%) underwent thoracoscopic repair per surgeon\'s choice. Type C accounted for 101 (97.1%) of the cases. Gestational age and birth weight were higher in the thoracoscopy group (p = 0.001). The rate of ≥3 VACTERL anomalies was higher in the OR group (p = 0.016). Operative time, rate of anastomotic leak, time to first oral feeding were similar (p > 0.05). Thoracoscopy group had decreased length of ventilation (p = 0.026) and length of stay (p = 0.029). The incidence of anastomotic stricture was higher in the thoracoscopy group (p = 0.012). Recurrent TEF was one case in each group. Rates of tube feeding at discharge and in first year were similar (p > 0.05), rate in third year was decreased (p = 0.032) in the thoracoscopy group. Rates of anti-reflux medication in first and third years, and fundoplication rate were similar (p > 0.05).
CONCLUSIONS: Many of the short- and long-term outcomes are comparable between thoracoscopic and open repair of EA/TEF. Length of ventilation, length of stay are decreased in the thoracoscopy group. Anastomotic stricture is higher, the need for long-term tube feeding is lower after thoracoscopic repair. Although these results could be affected by selection bias, they are still promising for advancing thoracoscopic repair of EA/TEF safely and efficiently.
METHODS: Level III.
