ObjectiveTo compare the intraoperative, postoperative indicators and economic costs of varicose veins patients between day surgery and inpatient surgery, and to explore the safety and benefit of large-scale varicose veins day surgery in China.MethodsA retrospective study was conducted to collect varicose veins patients in West China Hospital of Sichuan University from January 2016 to January 2019. Patients were divided into the day surgery group and the inpatient surgery group, and the subjects were matched by the propensity score matching (PSM) method according to the basic characteristic data. Intraoperative and postoperative indicators and economic costs were compared between the two groups.ResultsA total of 1 806 varicose vein patients were enrolled in the study, and 502 patients were enrolled in each of the two groups after PSM matching. After matching, there were no statistically significant differences in gender, age, nationality, marriage status, working status, residence, number of operative legs, medical insurance type, grade of American Society of Anesthesiologists, and complications (including hypertension, diabetes, coronary heart disease, and respiratory system diseases) between the two groups (P>0.05), which were comparable and the differences were not statistically significant. Compared with the inpatient surgery group, the day surgery group had shorter hospital stay, less intraoperative infusion volume, lower total cost, bed cost, nursing cost, drug cost, examination cost, medical insurance, and out-of-pocket (P<0.05). ConclusionThe varicose veins day surgery is not only safe and effective, but also can reduce the medication insurance payment.
Objective To explore the evolving strategies and compare perioperative and long-term outcomes of tricuspid valve replacement (TVR) in recent 20 years in our hospital.MethodsBetween 1998 and 2018, the clinical data of 608 patients who underwent TVR at the Department of Cardiac Surgery, Guangdong Provincial People’s Hospital were retrospectively analyzed. There were 201 males and 407 females, with a median age of 47.0 (36.0, 57.0) years. Patients were divided into a biological tricuspid valve (BTV, n=427) group and a mechanical tricuspid valve (MTV, n=181) group. Propensity score matching was used to balance the baseline difference. Surgical strategy evolving, postoperative and long-term outcomes were analyzed between the two groups.ResultsSince 2008, the usage ratio of biological valves was significantly higher than that of mechanical valves. Seventy-nine (13.0%) patients died in hospital after TVR. Before propensity score matching, the postoperative mortality of the BTV group was higher than that of the MTV group (15.2% vs. 7.7%, P=0.012), and there was no statistical difference between the two groups after matching (10.4% vs. 7.2%, P=0.372). The duration of postoperative ventilator support in the BTV group was longer than that in the MTV group [22.0 (15.0, 37.0) h vs. 19.0 (11.0, 27.0) h, P=0.003], and the incidence of postoperative dialysis and re-thoracotomy exploring for bleeding was higher in the BTV group (8.9 % vs. 2.8%, 9.4% vs. 6.6%, respectively). However, there was no statistical difference in mortality after matching. The median follow-up time of discharged patients was 101.0 (65.0, 147.0) months, ranged from 1 to 265 months, and the follow-up rate was 82.2%. During the follow-up period, there were 101 deaths (19.1%) of whom 68 were from the BTV group and 33 from the MTV group. The survival rates at 1 year, 5 years, 10 years, 15 years and 20 years of all patients were 85.0% (95%CI 82.2-87.9), 78.9% (95%CI 75.7-82.4), 71.1% (95%CI 67.3-75.3), 59.7% (95%CI 54.2-65.6) and 51.7% (95%CI 43.3-60.7), and there was no statistical difference between the two groups after matching (P=0.46). The median time of tricuspid valve failure was 84.0 (54.0-111.0) months.ConclusionTVR is associated with high perioperative risks. There is no statistical difference in early mortality and long-term survival between biological and mechanical valve, while patients with mechanical valve has higher risk of re-operation for valve failure. Therefore, the type of prosthetic valve can be selected according to the patients' age, physical condition and the doctors’ experience.
Objective To investigate the relationship between preoperative mean daily step counts and pulmonary complications after thoracoscopic lobectomy in elderly patients. Methods From 2018 to 2021, the elderly patients with pulmonary complications after thoracoscopic lobectomy were included. A 1∶1 propensity score matching was performed with patients without pulmonary complications. The clinical data were compared between the two groups. ResultsTotally, 100 elderly patients with pulmonary complications were enrolled, including 78 males and 22 females, aged 66.4±4.5 years. And 100 patients without pulmonary complications were matched, including 71 males and 29 females aged 66.2±5.0 years. There was no significant difference in the preoperative data between the two groups (P>0.05). Compared to the patients with pulmonary complications, the ICU stay was shorter (8.1±4.4 h vs. 12.9±7.5 h, P＜0.001), the first out-of-bed activity time was earlier (8.8±4.5 h vs. 11.2±6.1 h, P=0.002), and the tube incubation time was shorter (19.3±9.2 h vs. 22.5±9.4 h, P=0.015) in the patients wihout pulmonary complications. There was no statistical difference in other perioperative data between the two groups (P>0.05). The mean daily step counts in the pulmonary complications group were significantly less than that in the non-pulmonary complications group (4 745.5±2 190.9 steps vs. 6 821.1±2 542.0 steps, P＜0.001). The daily step counts showed an upward trend for three consecutive days in the two groups, but the difference was not significant. Conclusion The decline of preoperative mean daily step counts is related to pulmonary complications after thoracoscopic lobectomy in elderly patients. Recording daily step counts can promote preoperative active exercise training for hospitalized patients.
ObjectiveTo analyze and compare the perioperative efficacy difference between full-port Da Vinci robotic surgery and thoracoscopic surgery in patients with mediastinal tumor resection. MethodsThe data of 232 patients with mediastinal tumors treated by the same operator in the Department of Thoracic Surgery of the Second Affiliated Hospital of Harbin Medical University were included. There were 103 (44.4%) males and 129 (55.6%) females, with an average age of 49.7 years. According to the surgical methods, they were divided into a robot-assisted thoracic surgery (RATS) group (n=113) and a video-assisted thoracoscopic surgery (VATS) group (n=119). After 1 : 1 propensity score matching, 57 patients in the RATS group and 57 patients in the VATS group were obtained. ResultsThe RATS group was better than the VATS group in the visual analogue scale pain score on the first day after the surgery [3.0 (2.0, 4.0) points vs. 4.0 (3.0, 5.0) points], postoperative hospital stay time [4.0 (3.0, 5.5) d vs. 6.0 (5.0, 7.0) d] and postoperative catheterization time [2.0 (2.0, 3.0) d vs. 3.0 (3.0, 4.0) d] (all P<0.05). There was no statistical difference between the two groups in terms of intraoperative blood loss, postoperative complications, postoperative thoracic closed drainage catheter placement rate or postoperative total drainage volume (all P>0.05). The total hospitalization costs [51 271.0 (44 166.0, 57 152.0) yuan vs. 35 814.0 (33 418.0, 39 312.0) yuan], operation costs [37 659.0 (32 217.0, 41 511.0) yuan vs. 19 640.0 (17 008.0, 21 421.0) yuan], anesthesia costs [3 307.0 (2 530.0, 3 823.0) yuan vs. 2 059.0 (1 577.0, 2 887.0) yuan] and drug and examination costs [9 241.0 (7 987.0, 12 332.0) yuan vs. 14 143.0 (11 620.0, 16 750.0) yuan] in the RATS group was higher than those in the VATS group (all P<0.05). ConclusionRobotic surgery and thoracoscopic surgery can be done safely and effectively. Compared with thoracoscopic surgery, robotic surgery has less postoperative pain, shorter tube-carrying time, and less postoperative hospital stay, which can significantly speed up the postoperative recovery of patients. However, the cost of robotic surgery is higher than that of thoracoscopic surgery, which increases the economic burden of patients and is also one of the main reasons for preventing the popularization of robotic surgery.
ObjectiveTo investigate the safety, feasibility and advantages of subxiphoid uni-portal thoracoscopic thymectomy.MethodsClinical data of 65 patients undergoing subxiphoid uni-portal thoracoscopic thymectomy in our hospital from September 2018 to March 2019 were retrospectively analyzed. They were treated as a subxiphoid surgery group, including 36 males and 29 females, aged 49.5 (29-71) years. The incision with the length of about 3 cm was located approximately 1 cm under the xiphoid process. From January 2016 to December 2017, 65 patients received intercostal uni-portal thoracoscopic thymectomy, who were treated as a control group, including 38 males and 27 females, aged 48.9 (33-67) years. All patients who were clinically diagnosed with thymic tumor before surgery were treated with total thymectomy. After surgery, expectoration and analgesia were used.ResultsThere was no statistically significant difference in general clinical data, lesion size, intraoperative blood loss, postoperative catheterization time, postoperative hospital stay and postoperative pathology between the two groups. All operations were successfully completed, and the patients in both groups recovered uneventfully after surgery. Visual analogue scale scores on the 1st, 3rd, 7th and 30th day after surgery in the subxiphoid surgery group were lower than those in the control group.ConclusionThe subxiphoid uni-portal thoracoscopic approach can achieve total thymectomy with less trauma and faster postoperative recovery.
Objective To evaluate the diagnostic yield and safety of two biopsy methods, electromagnetic navigational bronchoscopy (ENB) and transthoracic needle biopsy (TTNB), in peripheral pulmonary lesions. To select a low-risk and high-benefit biopsy method based on the clinical characteristics of the lesions and patients. Methods A retrospective analysis was conducted on inpatients who underwent ENB and/or TTNB for peripheral pulmonary lesions in Huadong Hospital Affiliated to Fudan University. Propensity score matching was used to compare the diagnostic yield and safety of the two biopsy methods. Results A total of 126 patients were included in the ENB group, and 104 patients in the TTNB group. After propensity score matching, 83 matched pairs were obtained. The TTNB group exhibited a significantly higher diagnostic yield compared with the ENB group (90.4% vs. 48.2%, P<0.001), but it was also associated with a higher incidence of pneumothorax (1.2% vs. 21.7%, P<0.001). In the ENB group, the diagnostic efficacy was correlated with lesion diameter (P<0.001, OR=0.183, 95%CI 0.071 - 0.470), but there was no statistically significant difference in the diagnostic yield among different lung segments (P>0.05). In the TTNB group, lesion characteristics did not significantly affect the diagnostic yield, but a lesion diameter ≤30 mm (P=0.019, OR=5.359, 95%CI 1.320 - 21.753) and a distance from the pleura ≥20mm (P=0.030, OR=6.399, 95%CI 1.192 - 34.360) increased the risk of pneumothorax. When stratified based on lesion and patient blood characteristics, no significant difference was found in the diagnostic yield between the two groups for characteristics such as left upper lobe (P=0.195), right middle lobe (P=0.333), solid with cavity (P=0.567), or abnormal serum white blood cell count (P=0.077). However, the incidence of pneumothorax in the TTNB group was higher than that in the ENB group. Conclusions The diagnostic yield of ENB is affected by the size of the lesion, while the incidence of pneumothorax in TTNB is influenced by both lesion size and distance from the pleura. In cases with lesions located in the left upper lobe, right middle lobe, solid with cavity, or with abnormal serum white blood cell count, selecting ENB for biopsy is considered preferable to TTNB.
ObjectiveTo evaluate the incidence of postoperative atrial fibrillation (POAF) after dexmedetomidine and diazepam in patients undergoing coronary artery bypass grafting (CABG). MethodsA retrospective cohort study was conducted in the patients who underwent CABG in the General Hospital of Northern Theater Command from October 2020 to June 2021. By propensity score-matching method, the incidence of POAF after dexmedetomidine and diazepam application in patients undergoing CABG was evaluated. ResultsFinally 207 patients were collected, including 150 males and 57 females, with an average age of 62.02±8.38 years. Among the 207 patients, 53 were treated with dexmedetomidine and 154 with diazepam before operation. There was a statistical difference in the proportion of hypertension patients and smoking patients between the two groups before matching (P<0.05). According to the 1∶1 propensity score-matching method, there were 53 patients in each of the two groups, with no statistical difference between the two groups after matching. After matching, the incidence of POAF in the dexmedetomidine group was lower than that in the diazepam group [9.43% (5/53) vs. 30.19% (16/53), P=0.007]. There was no death in the two groups during hospitalization, and there was no statistical difference in the main adverse events after operation. The ICU stay (21.28±2.69 h vs. 22.80±2.56 h, P=0.004) and mechanical ventilation time (18.53±2.25 h vs. 19.85±2.01 h, P=0.002) in the dexmedetomidine group were shorter. Regression analysis showed that age, smoking and diabetes were related to the increased incidence of POAF (P<0.05), and preoperative use of dexmedetomidine was associated with a reduced incidence of POAF (P=0.002). ConclusionFor patients undergoing CABG, the incidence of POAF with dexmedetomidine before operation is lower than that with diazepam. Preoperative application of dexmedetomidine is the protective factor for POAF, and old age, smoking and diabetes are the risk factors for POAF.
ObjectiveTo analyze the incidence of complications, duration of chest tube indwelling, and nutritional status in tuberculosis (TB) patients undergoing pulmonary surgery, and to explore perioperative nutritional management strategies and rehabilitation measures by identifying nutritional factors influencing postoperative chest tube duration. MethodsA retrospective analysis was conducted on clinical data of TB patients who underwent lobectomy at the Department of Thoracic Surgery, Chengdu Public Health Clinical Medical Center from 2022 to 2023. Patients were grouped based on chest tube duration (≤7 days vs. >7 days) and propensity score matching (PSM) was performed. Complications, drainage volume, and nutritional status were compared between groups. Univariate and multivariate logistic regression analyses were used to identify factors associated with prolonged chest tube duration. ResultsAmong 276 enrolled patients, 163 had chest tube duration ≤7 days [pre-PSM: 91 males, 72 females, mean age of (34.88±14.10) years] and 113 had duration >7 days [pre-PSM: 69 males, 44 females, mean age of (39.04±13.28) years]. After PSM (45 patients per group), no significant differences were observed in pleural or pulmonary infection rates between groups (P>0.05). Univariate analysis revealed statistical differences in preoperative albumin-to-globulin ratio (A/G), 24-hour postoperative A/G, 24-hour postoperative prognostic nutritional index (PNI), pre-discharge A/G, and pre-discharge hemoglobin (P<0.05). Multivariate logistic regression identified the following independent risk factors for prolonged chest tube duration: preoperative A/G, 24-hour postoperative A/G, 24-hour postoperative PNI, pre-discharge A/G, and pre-discharge hemoglobin. ConclusionPreoperative A/G, 24-hour postoperative A/G and PNI, and pre-discharge A/G and hemoglobin significantly influence chest tube duration in TB patients. Preoperative nutritional-immunological indicators independently predict prolonged drainage, while dynamic postoperative monitoring provides comprehensive recovery assessment. Integrating these parameters enables early identification of high-risk patients, facilitates personalized drainage management, and may reduce hospitalization duration while improving prognosis.
ObjectiveTo compare the efficacy of varicose great saphenous vein (GSV) treatment alone versus combined treatment with iliac vein compression (IVC) intervention in improving lower extremity symptoms and prognosis among the patients with varicose GSV complicated by IVC. MethodsBased on inclusion and exclusion criteria, the patients with varicose GSV complicated by IVC treated at the Day Service Center of the First Affiliated Hospital of Chongqing Medical University from May 2022 to January 2025 were retrospectively enrolled. The patients were assigned into two groups according to the treatment strategies: the varicose GSV treatment alone group (control group) and the combined treatment group for varicose GSV and IVC (observation group). The primary endpoints included the closure rate of the GSV trunk, venous clinical severity score (VCSS), and venous insufficiency epidemiological and economic study quality of life/symptom (VEINES-QOL/Sym) questionnaire score at 6 and 12 months postoperatively. The significance level was set at α=0.05. ResultsA total of 264 patients with left lower extremity varicose GSV complicated by IVC were included. The observation group comprised 32 patients, while the remaining 232 patients underwent 1∶3 propensity score-matching, resulting in 96 matched patients in the control group. The baseline characteristics, including gender, age, and comorbidities, showed no statistically significant differences between the two groups (P>0.05). At 12 months postoperatively, the GSV trunk closure rate was 100% in both groups. Within-group comparisons revealed significant improvements in the VCSS and VEINES-QOL/Sym points at 6 and 12 months as compared with preoperative (on admission) values (P<0.05). Between-group comparisons showed that the observation group had greater improvement in the VEINES-QOL/Sym score at 6 months (P=0.028), but no significant difference in the VCSS (P=0.775); At 12 months, the observation group demonstrated significantly better the VCSS (P<0.001) and VEINES-QOL/Sym points (P<0.001) as compared with the control group. ConclusionsFor patients with left lower extremity GSV varicosities complicated by IVC, both treatment strategies significantly improve symptoms. Results of short-term follow-up (6 months) demonstrate early advantages in quality of life improvement with concurrent IVC intervention, while results of 12-month follow-up indicate superior efficacy in both symptom relief and quality of life enhancement. Therefore, concurrent IVC intervention may provide greater clinical benefits for mid- to long-term prognosis for patients with left lower extremity GSV varicosities complicated by IVC.
Objective To evaluate the strategy of chemoradiotherapy following endoscopic R0 resection for esophageal cancer in M3-T1b stage. Methods There were 45 esophageal cancer patients with M3-T1b stage with endoscopic R0 resection followed by additional chemoradiotherapy from ECETC (Esophageal Cancer Endoscopic Therapy Consortium) as a trial group with 34 males and 11 females at age of 61.37±7.14 years. There were 90 patients with esophagectomy from Fudan University Shanghai Cancer Center as a control group with 63 males and 27 females at age of 61.04±8.17 years. Propensity score match (1:2) was used to balance the factors: gender, age, position, depth of invasion and lymphovascular invasion (LVI), which may influence the outcomes. Overall survival (OS) rate, relapse free survival (RFS) rate, and local recurrence rate were compared between the two groups. Result There was no statistical difference (HR=2.66 with 95%CI 0.87 to 8.11, P=0.179) in terms of OS rate between the two groups. One, two and three years overall survival rate of patients in the control group was 93%, 86%, and 84%, respectively. Nobody died in the trial group within 3 years after surgery. The RFS rate between the two groups didn’t significantly differ (HR=1.48, 95% CI 0.66 to 3.33, P=0.389). One, two and three years RFS rate of patients in the contorl group was 87%, 78%, and 76%, respectively, while 97%, 93%, and 73% in the trial group, respectively. The local recurrence rates between the two groups didn’t significantly differ either ( HR=0.53, 95%CI 0.13 to 2.18, P=0.314). One, two and three years local recurrence rate of patients in the control group was 5%, 6% and 6%, respectively, while 0%, 0% and 21% in the trial group, respectively. Conclusion Similar outcomes are found regarding OS, RFS and local recurrence rates between the two groups. The strategy of endoscopic R0 resection followed by additional chemoradiotherapy has prospect for the treatment of esophageal cancer in M3-T1b stage. And this kind of therapy may be provided for those with risk factors or can not tolerate surgery.
