ObjectiveTo investigate the clinical effect of metal supported multi-sided versus ordinary ultra-fine drainage tube in the uniportal video-assisted thoracic surgery (VATS) lower pulmonary lobectomy. MethodsFrom January 2021 to June 2022, the clinical data of patients who underwent uniportal VATS lower lobectomy in our hospital were retrospectively analyzed. According to the different types of ultra-fine drainage tubes used in the surgery, the patients were divided into an experimental group (using multi-sided hole 10F ultra-fine drainage tubes with metal support) and a control group (using ordinary 12F ultra-fine drainage tubes). The clinical data of the two groups were compared. ResultsA total of 190 patients were enrolled, including 108 males and 82 females. There were 90 patients in the experimental group aged 56.60±10.14 years; and 100 patients in the control group aged 57.07±11.04 years. The incidences of postoperative lung infection and pleural effusion in the experimental group were lower than those in the control group, with statistically significant differences (P<0.05). The postoperative visual analogue scale score, the need to adjust the chest drainage tube after the surgery, the need for chest puncture after the surgery, the time of postoperative chest tube removal, and the hospitalization cost were statistically different (P<0.05). There was no statistical difference in the length of postoperative hospital stay or the incidences of postoperative lung leakage, arrhythmia, and atelectasis complications (P>0.05). ConclusionCompared with the ordinary ultra-fine drainage tubes, multi-sided hole ultra-fine drainage tubes with metal support can reduce the incidences of lung infection and pleural effusion complications after the uniportal VATS lower lobectomy, reduce the pain and economic burden, which can be applied in the uniportal VATS lower lobectomy.
Objective To investigate the application of enhanced recovery after surgery (ERAS) in da Vinci robotic McKeown surgery for esophageal cancer. Methods Clinical data of patients admitted to the First Hospital of Lanzhou University and undergoing da Vinci robotic McKeown surgery for esophageal cancer from 2017 to 2021 were retrospectively analyzed. According to the treatment, they were divided into two groups, a conventional group and an ERAS group. Patients in the conventional group were treated with the conventional perioperative treatment mode of thoracic surgery, and patients in the ERAS group were treated with accelerated rehabilitation surgical treatment mode. Relevant hospitalization indicators and postoperative complication rates were compared between the two groups. Results Finally 128 patients were collected, including 106 males and 22 females, with an average age of 61.91 years. There were 71 patients in the conventional group and 57 patients in the ERAS group. The postoperative pain index in the ERAS group was significantly lower than that in the conventional group (P<0.05), and the duration of postoperative analgesic pump used in the ERAS group was shorter than that in the conventional group (2.39±0.49 d vs. 3.13±0.63 d, P<0.001). There was no statistical difference in the incidence of postoperative related complications (gastroesophageal reflux, anastomotic stenosis, anastomotic fistula, arrhythmia, recurrent laryngeal nerve injury, chylothorax, anastomosis stomatitis or incisional infection) between the two groups (P>0.05), but the incidence of postoperative lung infection in the ERAS group was statistically lower (12.28% vs. 26.76%, P=0.043), and the volume of postoperative pleural effusion was statistically less compared with the conventional group (P<0.05). In the ERAS group, the surgery time (294.35±15.19 min vs. 322.79±59.09 min, P<0.001), postoperative exhaust time (1.44±0.39 d vs. 1.94±0.43 d, P<0.001), postoperative removal time of nasolasal tube (6.79±0.73 d vs. 8.21±0.86 d, P<0.001), hospital stay (19.88±3.36 d vs. 21.34±3.59 d, P=0.020), hospitalization costs (105 575.28±8 960.75 yuan vs. 137 894.64±19 518.60 yuan, P<0.001) were all lower or shorter than those of the conventional group. Postoperative activity was longer in the ERAS group than that in the conventional group (P<0.05), but there was no statistical difference in preoperative anesthesia time between the two groups (P=0.841). Conclusion The application of ERAS in da Vinci robotic McKeown surgery for esophageal cancer can effectively alleviate the physiological and psychological burden of patients, reduce the occurrence of postoperative related complications, effectively shorten the total hospital stay, save hospitalization costs, and reduce the economic burden of patients and society. Therefore, it can be promoted and applied in the clinic.
ObjectiveTo analyze the early- and middle-term prognosis of various surgical methods in children with congenital aortic valve diseases, to provide reference for surgical methods in children with aortic valve stenosis or regurgitation.MethodsThe clinical data of 85 children with various aortic valve diseases treated in the Children’s Hospital of Fudan University from January 2005 to December 2018 were retrospectively analyzed. There were 64 males and 21 females, with an average age of 45 months ranging from 5 days to 15 years. Among them 18 patients underwent balloon aortic valvuloplasty (BAV), 8 surgical aortic valvotomy (SAV), 27 aortic valve autogenous pericardium repair, 16 mechanical arterial valve replacement and 16 Ross operation. They were followed up for 6.25±2.76 years. The re-intervention and survival status after different operations were analyzed.ResultsThere were 3 deaths and 17 reoperations in 85 children. The 5-year survival rate of the patients with SAV, BAV, aortic valve autogenous pericardium repair, mechanical arterial valve replacement and Ross operation was 87.4%, 88.9%, 100.0%, 100.0% and 100.0%, respectively; there was no statistical difference in the early and middle-term survival rates among various operations (P>0.05). The 5-year free from re-intervention rate of the patients with SAV, BAV, aortic valve autogenous pericardium repair, mechanical arterial valve replacement and Ross operation was 44.4%, 18.4%, 100.0%, 66.9% and 80.5%, respectively; there was a statistical difference in the early and middle-term re-intervention rate among various operations (P<0.05).ConclusionThe operation of congenital aortic stenosis or regurgitation needs to be performed according to the pathological changes of the valvular tissues. For children with severe lesions, SAV is recommended for the first intervention. For congenital aortic stenosis, SAV and BAV are both palliative operations which need further evaluation and re-intervention. Ross operation and mechanical arterial valve replacement have low re-intervention rate, and the middle- and long-term follow-up shows that the effect is accurate. Aortic valve autogenous pericardium repair is expected to become a method to delay or replace Ross operation and valve replacement.
Objective To explore the effect of aortic valve neo-cuspidization (AVNeo) for patients with severe aortic valve lesions simultaneously. Methods Patients who underwent AVNeo combined valve repair surgery for multiple valve diseases were included in Beijing Anzhen Hospital from May 2016 to September 2023. Results We included 11 patients with 7 males and 4 females at a median age of 38 (36, 49) years. Rheumatic heart disease was found in 5 (45.5%) patients and non-rheumatic heart disease in 6 (54.5%) patients. The median EuroSCORE Ⅱ score was 1.62 (1.18, 1.75) points. Eight patients underwent AVNeo plus mitral and tricuspid valve repair, and 3 patients underwent AVNeo plus mitral valve repair. The median operative time was 356 (315, 415) min, and the median cardiopulmonary bypass time and aortic clamping time were 203 (174, 231) min and 168 (131, 188) min, respectively. In the early stage, 2 patients underwent combined valve repair surgery, and 1 patient underwent in-hospital reoperation for aortic valve replacement because of severe aortic regurgitation. There were 9 patients in the mature stage of AVNeo, and no perioperative adverse events or moderate or above residual valvular disease occurred. All patients recovered and were discharged from the hospital. The follow-up period was 3-99 months, and no reoperation, severe valve disease, bleeding, cerebral infarction, or other adverse events occurred in all patients. Conclusion For non-elderly patients whose mitral and tricuspid valves can be repaired successfully with severe aortic valve lesions, AVNeo can be attempted after proficiency. But the operation time and cardiopulmonary bypass time will inevitably be prolonged, and the patient's basic situation should be carefully evaluated before surgery.
Objective To examined gene mutations in thymic carcinoma (TC) patients and to explore prognostic correlates and potential targets for therapy. MethodsWe retrospectively included TC patients in Sichuan Cancer Hospital between January 2015 and Febuary 2021.Whole-exome sequencing was performed on tumor tissues from TC patients and their control peripheral blood samples, and the raw data were subjected to bioinformatics analysis and statistical analysis. Results We finally included 24 TC patients with 16 males and 8 females at a median age of 55 (42-74) years. The highest frequency of single nucleotide mutations in this cohort were in the TTN gene (42%), HSPG2 (29%), and OBSCN (29%). Higher frequency of copy number variations occurred in ZNF276 gene (54%, loss), BEND3 (50%, loss), DHODH (50%, loss), and VAC14 (50%, loss). Microsatellite instability (MSI) phenotype was found in 25% of the patients, and the mean tumor mutation burden (TMB) was 9.86. Conclusion This study is the first comprehensive analysis of the mutation profile of thymic carcinoma in China to date. The mutation frequencies of TTN, OBSCN, and ZNF276 genes were high. The biomarker analysis suggests that patients may benefit from immunotherapy and have a long effective survival.
ObjectiveTo compare the surgical effects of total endoscopy and right thoracic small-incision for atrial septal defect repair.MethodsThe clinical data of 60 patients undergoing atrial septal defect repair in our hospital in 2019 under cardiopulmonary bypass (CPB) were collected. The patients were divided into two groups according to different surgical methods: a right thoracic small-incision group (n=31), including 11 males and 20 females, aged 44.5±11.5 years; a thoracoscopic surgery group (n=29), including 12 males and 17 females, aged 46.5±12.7 years. The clinical data were compared between the two groups.ResultsThe baseline data of the patients were not statistically different (P>0.05). The surgeries were successfully completed in the two groups of patients. The volume of chest drainage in 24 h after the surgery (59.1±43.9 mL vs. 91.0±72.9 mL, P=0.046), red blood cell input (78.0±63.9 mL vs. 121.0±88.7 mL, P=0.036), length of postoperative hospital stay (5.5±2.1 d vs. 7.2±2.1 d, P=0.003), postoperative complications rate (6.9% vs. 22.6%, P=0.029) in the thoracoscopic surgery group were significantly better than those in the right thoracic small-incision group. There was no significant difference in the CPB time, aorta blocking time, operation time, mechanical ventilation time, ICU retention time or postoperative pain score between the two groups (P>0.05).ConclusionThe two techniques are safe and effective. Patients undergoing thoracoscopic repair of atrial septal defect have small trauma, short postoperative hospital stay, mild pain, beautiful incision, and no bone damage, which is worthy of clinical promotion.
ObjectiveTo investigate the impact of postoperative application of Pseudomonas aeruginosa injection on recurrence free survival (RFS) and overall survival (OS) in patients with abnormal serum calcitonin levels following surgery for medullary thyroid carcinoma (MTC). MethodsA retrospective collection of data was conducted for 214 patients with abnormal serum calcitonin levels following MTC surgery at West China Hospital of Sichuan University from January 2015 to April 2024. Propensity score matching (1∶2) was utilized to match patients’ data to reduce confounding bias, comparing RFS and OS between patients who used (Pseudomonas group) and did not use (control group) Pseudomonas aeruginosa injection. ResultsAfter propensity score matching, 72 patients with abnormal postoperative calcitonin levels were included, with 24 in the Pseudomonas group and 48 in the control group. The median follow-up time for the 72 patients was 66 months (11–168 months). The 1-year RFS rates for the Pseudomonas group and the control group were 100% and 75.0%, respectively, and the 2-year RFS rates were 87.5% and 56.3%, respectively. The RFS in the Pseudomonas group was superior to that in the control group (χ2=4.791, P=0.029). The 5-year OS rates for the Pseudomonas group and the control group were 90.9% and 93.5%, respectively, with no significant difference between the two groups (χ2=0.469, P=0.491). The Cox proportional hazards regression model indicated that the median RFS was extended in the Pseudomonas group [25 months vs. 21 months, RR=0.350, 95%CI (0.135, 0.900), P=0.029], but there was no significant impact on OS [66 months vs. 69 months, RR=2.22, 95%CI (0.229, 21.444), P=0.503]. ConclusionPostoperative use of Pseudomonas aeruginosa injection in MTC patients with abnormal serum calcitonin level shows significant improvement in RFS, but no significant change in OS.
Objective To compare the mid- and long-term efficacy of minimally invasive coronary artery bypass grafting (MICS) versus conventional coronary artery bypass grafting (CABG). Methods This study analyzed 679 patients with coronary heart disease treated in the Minimally Invasive Heart Center of Beijing Anzhen Hospital from 2015 to 2019, including 532 males and 147 females with an average age of 61.16 years. A total of 281 patients underwent MICS (a MICS group) and 398 patients underwent conventional CABG (a CABG group). The clinical data of the patients in the two groups were analyzed. ResultsThe average operation time was longer (P<0.001), the total hospital stay was shorter (P<0.001), and the amount of drainage 24 h after the operation was less (P=0.029) in the MICS group. There was no statistical difference in the incidence of perioperative complications between the two groups. The median follow-up time was 2.68 years. The follow-up results showed that the total incidence of cumulative main adverse cardiovascular and cerebrovascular events in the CABG group was higher at 2 years (6.2% vs. 3.8%) and 4 years (9.3% vs. 7.6%), but the difference was not statistically significant (P>0.05). There was no statistical difference in 2- or 4-year all-cause death between the two groups (3.5% vs. 2.8%, 5.6% vs. 2.8%, P>0.05). At the same time, there was no statistical difference in the incidence of myocardial infarction, stroke or revascularization between the two groups (P>0.05). ConclusionCompared with conventional CABG, MICS can achieve satisfactory mid- and long-term outcomes.
ObjectiveTo analyze the clinical efficacy of transcatheter tricuspid valve replacement (TTVR) in cardiac implantable electronic lead-related tricuspid regurgitation (TR). MethodsThe patients with severe TR who underwent LuX-Valve TTVR in 9 Chinese medical centers from June 2020 to August 2021 were retrospectively enrolled. They were divided into a cardiac implantable electronic device (CIED) group and a non-CIED group based on whether they had pre-existing CIED implantation. Success of the procedure was defined as safe implantation of the LuX-Valve and complete withdrawal of the delivery system. Prognostic improvement was defined as a decrease of TR grade to≤2+ and an improvement of cardiac function by≥2 grades. Surgical success and postoperative prognosis were compared between the two groups. ResultsA total of 190 patients were collected, including 50 males and 140 females with a mean age of 66.2±7.8 years. There were 29 patients in the CIED group, and 161 patients in the non-CIED group. In the CIED group, 28 patients were implanted with a permanent pacemaker and 1 patient with a cardioverter-defibrillator. Preoperative New York Heart Association (NYHA) cardiac function class, TR degree, left ventricular ejection fraction, tricuspid annular plane systolic excusion, and cardiac risk scores were comparable between the two groups (P>0.05). Postoperative TR was reduced to≤2+ in all patients, and there was no statistical difference in the incidence of perivalvular leakage between the two groups (P=0.270). Postoperative CT of CIED patients showed the valve was in place, and the lead was not extruded, twisted, or deflected. The in-hospital mortality of the two groups were 10.3% and 1.9%, respectively, and the difference was statistically significant (P=0.047). In addition, there was no statistical difference between the two groups in terms of postoperative improvement of cardiac function and mortality in the 1- and 2-year follow-up. ConclusionTTVR is feasible, safe, and effective in patients with CIED implantation, and the pre-existing lead has no significant effect on the clinical efficacy.
ObjectiveTo explore the clinical effect of tubeless 3 mm ultra-fine thoracoscope combined with needle electrocoagulation hook thoracic sympathicotomy in the treatment of primary palmar hyperhidrosis. MethodsThe clinical data of 77 patients with primary palmar hyperhidrosis who underwent surgery in the First Hospital of Lanzhou University from September 2017 to July 2021 were retrospectively analyzed, including 50 males and 27 females, with an average age of 23.60±5.60 years. A total of 36 patients were treated with tubeless 3 mm ultra-fine thoracoscopic electrocoagulation hook thoracic sympathicotomy (an observation group), and 41 patients were treated with conventional thoracoscopic thoracic sympathicotomy (a control group). The baseline data, perioperative data and the results of 12 hours after operation were compared between the two groups. ResultsAll the 77 patients completed the operation successfully, no conversion to thoracotomy, no intraoperative bleeding, and no conversion to endotracheal intubation in the observation group. In the observation group, the time of anesthesia before operation [19.00 (17.00, 23.75) min vs. 25.00 (21.00, 27.00) min, P=0.001] and postoperative hospital stay [2.00 (1.00, 2.00) d vs. 2.00 (1.00, 3.00) d, P=0.012] were shorter than those in the control group. The operation time [22.50 (21.00, 25.75) min vs. 26.00 (23.50, 28.50) min, P=0.001], intraoperative blood loss [5.00 (2.25, 5.00) mL vs. 6.00 (5.00, 10.00) mL, P=0.003], postoperative pain index [2.00 (1.00, 2.00) vs. 3.00 (2.00, 3.00), P=0.001], hospitalization cost (14 246.58±879.28 yuan vs. 15 085.90±827.15 yuan, P<0.001) and postoperative inflammation index: white blood cell count [(12.96±2.32)×109/L vs. (14.47±2.05)×109/L, P=0.003], percentage of neutrophils (76.31%±5.40% vs. 79.97%±7.12%, P=0.014) were significantly lower or less than those in the control group. There was no significant difference in the incidence of major postoperative complications or adverse consequences between the two groups (P>0.05). In the evaluation of 12 hours after operation, the time of getting out of bed [2.00 (1.00, 2.00) h vs. 2.00 (2.00, 3.00) h, P=0.017], the time of drinking water after operation [1.50 (1.00, 2.00) h vs. 2.00 (1.00, 3.00) h, P=0.005], and the heart rate (80.25±14.42 bpm vs. 91.07±15.08 bpm, P=0.002), the incidence of dizziness, nausea and other uncomfortable symptoms (5.6% vs. 25.0%, P=0.040) at 12 hours after operation were shorter or lower than those in the control group. There was no significant difference in blood oxygen saturation (non-inhaled oxygen state) 12 hours after the operation between the two groups [97.00% (95.25%, 98.00%) vs. 97.00% (96.00%, 98.00%), P=0.763]. ConclusionCompared with conventional thoracoscopic thoracic sympathicotomy, tubeless 3 mm ultra-fine thoracoscopic electrocoagulation hook thoracic sympathicotomy can significantly shorten the operation time, reduce postoperative pain and promote postoperative recovery, in line with the concept of accelerated rehabilitation surgery and minimally invasive surgery, and is worth popularizing in clinical practice.
