ObjectiveTo investigate the safety and efficacy of 3D thoracoscopic surgery in uniportal lobectomy.MethodsClinical data of 248 patients with lung cancer who underwent uniportal thoracoscopic lobectomy in our hospital from September 2018 to May 2019 were retrospectively analyzed. Patients were divided into two groups according to different surgical methods, a 3D thoracoscopic group (76 patients, including 52 males and 24 females with an average age of 58.59±7.62 years) and a 2D thoracoscopic group (172 patients, including 102 males and 70 females with an average age of 57.75±8.59 years). Statistical analysis of clinical and pathological data, lymph node dissection, surgical complications, postoperative hospital stay, etc was performed.ResultsCompared with the 2D thoracoscopic group, the 3D thoracoscopic group had shorter operation time, more lymph nodes dissected and pleural effusion on the first day after operation (P<0.05). There was no significant difference in the postoperative chest tube duration, postoperative hospital stay, incidence of pulmonary infection, arrhythmia, bronchopleural fistula, or recurrent laryngeal nerve injury between the two groups.ConclusionCompared with the traditional 2D thoracoscopic minimally invasive surgery, uniportal lobectomy with 3D thoracoscopic surgery is safer and more efficient during operation, and lymph node dissection is more thorough, which is worth promoting.
Surgical treatment of atrial septal defect (ASD) mainly includes occlusion or repair under cardiopulmonary bypass. Surgical treatment of atrial fibrillation includes transcatheter radiofrequency ablation or Maze surgery under cardiopulmonary bypass. There are many treatments for ASD patients combined with atrial fibrillation, but each has its own advantages and disadvantages. We reported an ASD patient combined with atrial fibrillation treated by totally endoscopic "one-stop" radiofrequency ablation and simultaneous transthoracic ASD occlusion of atrial fibrillation, with good postoperative results.
ObjectiveTo analyze the effect of loop-in-loop technique and annuloplasty ring for the treatment of mitral valve prolapse (MVP) under total thoracoscopy.MethodsBetween May 2012 and May 2017, 21 patients with MVP underwent mitral valve repair in our hospital. There were 12 males and 9 females with a mean age of 50.90±9.66 years and the mean weight of 64.81±11.56 kg. Loop-in-loop artificial chordae tendonae reconstruction and mitral annuloplasty were performed through the right atrial-atrial septal incision under total thoracoscopy. The water test and transesophageal echocardiography were performed during the operation to evaluate the effect of mitral annuloplasty. Data of echocardiography and chest radiography were collected postoperatively one week, before discharge and after discharge.ResultsAll the operations were successful without re-valvupoplasty or valve replacement, conversion to median thoracotomy, malignant arrhythmia, perioperative death or wound infection. Among them, 10 patients underwent tricuspid valvuloplasty, 1 patient underwent tricuspid valvuloplasty plus radiofrequency ablation simultaneously. The mean cardiopulmonary bypass time was 255.57±37.24 minutes, aortic occlusion time was 162.24±19.61 minutes, the number of loop was 2–5 (3.29±0.78), the size of ring was 28–34 (31.11±1.88) mm, ventilator assistance time was 19.43±14.68 hours, ICU time was 58.45±24.60 hours and postoperative hospital stay was 12.28±3.61 days. Transthoracic echocardiography was re-examined postoperatively. Mild-mitral regurgitation was found in 3 patients. Warfarin anticoagulant therapy was given orally for 6 months postoperatively. The patients were followed up regularly for 2–51 months at 1, 3, 6 and 12 months postoperatively. Left ventricular end-diastolic diameter (LVEDD) was 45.06±2.96 mm, left ventricular end-diastolic volume 108.11±17.09 mL, left atrial diameter (LAD) 35.56±6.93 mm and cardiothoracic ratio 0.53±0.13 at discharge which were significantly smaller than those at admission (P<0.05). Pulmonary artery pressure was 19.22±6.38 mm Hg which was significantly lower than that at admission (P<0.05), but left ventricular ejection fraction (62.33%±4.00%) had no significant change (P>0.05). The LAD and LVEDD were significantly smaller than those before operation, and the cardiac function improved to some extent during the follow-up. No new mitral valve prolapse, increased regurgitation, infective endocarditis, thromboembolism or anticoagulation-related complications were found during the follow-up.ConclusionLoop-in-loop artificial chordae tendon implantation combined with mitral annuloplasty is a safe and effective method for MVP under total thoracoscopy with minimal trauma, satisfactory cosmetic effect, and good early- and medium-term results. It is worth of popularizing. However, the operation time needs to be further shortened, and its long-term clinical effect needs further follow-up and other researches to confirm.
ObjectiveTo investigate the relationship between the nodule manifestation of malignant pleural lesions under medical thoracoscopy and pleural fluid biochemistry and tumor marker levels. MethodsA total of 110 patients with malignant pleura, including 90 cases of lung cancer, 18 cases of malignant mesothelioma, 1 case of diffuse large B-cell lymphoma, and 1 case of ovarian serous carcinoma, who were hospitalized in the Department of Respiratory and Critical Care Medicine, East Hospital of Shandong Provincial Hospital from February 2011 to January 2022 were selected as the study subjects. The pleural nodule manifestation was divided into 6 layers were according to the number of pleural nodules in the medical thoracoscopic field, they were divided into 6 layers: non-nodular group, nodular group (pleural nodules of different sizes were distributed); The nodular group was further divided into nodular scattered group (total number of pleural nodules in all fields under thoracoscopy ≤10) and nodular diffuse group (total number of pleural nodules in all fields under thoracoscopy >10); The nodular diffuse group was further divided into the multiple nodules diffused group (the total number of pleural nodules >10 under thoracoscopy and ≤10 nodules in a single microscopic field) and the nodular diffuse patchwork group (the total number of pleural nodules >10 under thoracoscopy and >10 nodules in a single microscopic field). Four biochemical items of pleural fluid, pleural fluid lactate dehydrogenase (LDH), adenosine deaminase (ADA), glucose (GLU), protein quantification (TP) levels and pleural fluid carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125) levels, serum CEA, and serum cytokeratin fragment 19 (CYFRA21-1) levels were measured to compare the expression levels of indicators between the non-nodular group and the nodular group, the nodular scattered group and the nodular diffuse group, the multiple nodules diffused group and the nodular diffuse patchwork group.ResultsThe LDH level in pleural fluid of nodular group was significantly higher than that of non-nodular group (P<0.01). The LDH level in pleural fluid of diffuse nodular group was higher than that of scattered nodular group (P<0.05). Compared to those in multiple nodules diffused group, the levels of LDH and ADA in pleural fluid of nodules patchy diffused group were significantly increased (P<0.01), and the GLU level was decreased (P<0.05). However, there were no statistically significant differences in the length of disease, smoking index, TP in pleural fluid, CEA in pleural fluid, CA125 in pleural fluid, CEA in serum and CYFRA21-1 in serum between the paired groups.ConclusionsThere were differences in the expression levels of LDH, ADA and GLU in pleural fluid of different degrees of malignant pleural lesions. The higher the degree of pleural lesions, the higher the levels of LDH and ADA in pleural fluid and the lower the levels of GLU in pleural fluid.
Abstract: Objective To explore the outcomes of videoassistedthoracoscopic surgery (VATS) in the treatment of esophageal leiomyoma. Me thods [WTBZ] We reviewed and analyzed the clinical data of 87 patients with esophageal leiomyoma treated with VATS in Changhai Hospital of Second Military Medical University between June 2002 and January 2009. [WTHZ]Results [WTBZ]Videoassisted thoracoscopic leiomyoma enucleations was performed in 80 patients, whilea conversion to minithoracotomy was required in 7 others. All procedures werecompleted smoothly and the postoperative recovery was uneventful, without mortality or severe complications. The patients were drinking liquids from postoperative day 1 and were eating a normal diet from day 3. All patients were pathologically diagnosed with leiomyoma after operation. Followups of 6 months to 6.5 years (mean: 3.8 years) found no recurrence. [WTHZ] Conclusion [WTBZ]Videoassisted thoracoscopic enucleation can be the first choice for esophageal leiomyomas derived from lamina propria. Patients with esophageal leiomyomas of diameter gt;1.0 cm should be treated with VATS .
ObjectiveTo study the clinical results of Mini Maze procedure in atrial fibrillation patients with impaired left ventricular systolic function.MethodsFrom June 2010 to December 2017, 86 atrial fibrillation patients with impaired left ventricular systolic function received Mini Maze procedure including 54 males and 32 females, with an average age of 60.7±5.9 years. Among them, 12 were with paroxysmal, 27 were with persistent and 47 were with long-standing persistent atrial fibrillation. The mean atrial fibrillation duration was 6.5±4.8 years. CHA2DS2-VASc score was 2.2±1.1. The mean diameter of left atrium was 46.9±3.8 mm. The mean diameter of left ventricle was 51.7±4.6 mm. The preoperative ejection fraction was 42.2%±4.7%. All patients received Mini Maze procedure after general anesthesia. The ablation included 3 annular ablations and 3 linear ablations. The left atrial appendage was excised by Endo-Gia. Ablation of Marshall ligament and epicardial autonomic ganglions were made by an ablation pen.ResultsEighty-six patients successfully completed the procedure without transition to thoracotomy. There was no death during the perioperative period. Seventy-seven patients (89.5%) maintained sinus rhythm at discharge. Eighty patients were followed up for 27.2±12.1 months and 72 patients maintained sinus rhythm. The overall postoperative left ventricular ejection fraction was 47.1%±6.2%. The ejection fraction of the postoperative sinus rhythm group was 48.2%±5.8%, and the ejection fraction of the non-sinus group was 41.6%±5.8% (P<0.05). Multivariate regression analysis showed a left atrial diameter (HR=1.485, 95%CI 1.157-1.906, P<0.05) and an increase in ejection fraction over 10% (HR=18.800, 95%CI 1.674-189.289, P<0.05) were closely related to postoperative recurrence. Kaplan-Meier curve analysis showed that the recurrence rate of atrial fibrillation was significantly lower in patients with an increase in postoperative ejection fraction over 10% (P<0.05).ConclusionMini Maze procedure is safe and effective in the treatment of atrial fibrillation patients with left ventricular systolic dysfunction, which helps to improve left ventricular function to prevent the vicious circle of atrial fibrillation and heart failure.
Thoracoscopic mitral valve replacement is a common minimally invasive cardiac surgery procedure. However, small annulus, severe calcification of the annulus, and severe thickening of the posterior valve leaflet or sub valvular structure are the difficulties of thoracoscopic mitral valve replacement. Improper treatment can easily lead to left ventricular rupture or prosthesis-patient mismatch. This paper reports a thoracoscopic mitral bioprosthesis replacement case using the chimney technique in Guangdong Provincial People's Hospital and summarizes its operating key points. The patient was a 68-year-old female, weighing 36 kg. The preoperative diagnosis was rheumatic mitral stenosis and atrial fibrillation, the preoperative transthoracic echocardiogram showed the left ventricular end-diastolic diameter was 39 mm. The surgical effect was satisfactory. The patient was in good condition at the follow-up 2 months after the operation.
ObjectiveTo explore the clinical efficacy of thoracoscopy-assisted modified Nuss procedure for pectus excavatum (PE) in children.MethodsThe clinical data of patients with PE who underwent thoracoscopy-assisted modified Nuss procedure from October 2013 to October 2020 in Daping Hospital were retrospectively analyzed.ResultsA total of 86 patients were collected, including 79 males and 7 females with a mean age of 14.03±3.36 years. The operations were performed successfully in all patients without intraoperative cardiac vascular injury or perioperative death. The mean operation time was 87.30±33.45 min, bleeding volume was 19.94±14.60 mL, and the postoperative hospitalization stay time was 6.89±2.59 d. Early postoperative complications included 2 patients of pneumothorax, 2 patients of wound fat liquefaction and infection, 2 patients of bar flipping and displacement. One patient had bar displacement 1 year after the surgery. The total complication rate was 8.14%. All patients were followed up for 3-42 months. The bars were taken out about 36 months after the surgery. According to the evaluation criteria of orthopedic effect, 68 (79.07%) patients were excellent, 10 (11.63%) patients were good, 5 (5.81%) patients were moderate and 3 (3.49%) patients were poor.ConclusionMinimally invasive and individualized shaping via the Nuss procedure for PE children is safe and convenient, with satisfied effect. It is worthy of popularization in the clinic.
Objective To analyze the safety and effectiveness of ultrasound-guided thoracoscopic atrial septal defect (ASD) closure. Methods We prospectively collected the clinical data of 12 patients with ASD treated by ultrasound-guided thoracoscopic ASD closure in Fuwai Hospital from January to September 2017. The characteristics of the patients' ASD and operation, operation safety and effectiveness, postoperative complications and follow-up results were analyzed. Results Among the 12 patients, 10 were successfully treated with ultrasound-guided thoracoscopic ASD closure. Two patients switched to ASD repair under thoracoscopy-assisted cardiopulmonary bypass. The size of the ASD was 17-40 (27.22±8.97) mm and the size of the occluder was 36 (30-42) mm. The average postoperative length of hospital stay was 6 days. There were no complications such as arrhythmia, bleeding and pericardial effusion after operation. The average follow-up was 6 (3-10) months after the operation. During the follow-up, no Ⅲ-degree conduction block, occluder dislocation, residual shunt or cardiac pericardial effusion was found. Conclusion Ultrasound-guided thoracoscopic ASD closure is a minimally invasive, safe and effective treatment. This technique provides a new minimally invasive surgical option for patients with large defect diameter and poor edge condition.
Objective To explore the safety and feasibility of spontaneous breathing anesthesia combined with tubeless uniportal thoracoscopy in pulmonary bullae surgery. Methods Totally 112 patients with pulmonary bullae in the Affiliated Hospital of Inner Mongolia Medical University from March 2015 to May 2017 were enrolled. According to the random number chosen by computer, the patients were randomly divided into two groups: a tubeless group (spontaneous breathing anesthesia combined with tubeless uniportalthoracoscopy) and a control group (uniportal thoracoscopy by general anesthesia with tracheal intubation) . There were 49 males and 7 females with an average age of 25.5±6.5 years in the tubeless group, and 50 males and 6 females with an average age of 23.5±4.5 years in the control group. The difference of the lowest intraoperative arterial oxygen saturation (SaO2), SaO2 at postoperative one hour, operation time, postoperative awakening time, hospital stay, hospitalization cost and postoperative pain score were analyzed. Results There was no significant difference between the two groups in the operation time, the lowest SaO2, SaO2 at one hour after the operation and the partial pressure of carbon dioxide (PaCO2). The awakening time and duration of postoperative hospital stay in the tubeless group was shorter than those in the control group (P=0.000). The cost of hospitalization in the tubeless group was less than that in the control group (P=0.000). The discomfort caused by urinary tract and visual analogue score (VAS) in the tubeless group were better than those in the control group. Conclusion It is safe and feasible to use spontaneous breathing anesthesia combined with tubeless uniportal thoracoscopy in pulmonary bullae resection.
