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.
ObjectiveTo explore the effect of body mass index (BMI) on the outcomes of laparoscopic surgery for esophageal hiatal hernia.MethodsWe divided the patients who underwent hiatal hernioraphy and fundoplication surgery in our hospital between July 2013 and June 2018 into two groups according to the BMI: a group A, BMI ≥24 kg/m2, 77 patients, 41 males, 36 females, with an average age of 42 years; a group B: BMI<24 kg/m2, 63 patients, 38 males, 25 females, with an average age of 67 years, and the age, gender, type of hiatal hernia, score of subjective feeling of symptoms, level of reflux esophagitis were analyzed with the propensity score matching method. Fifty one patients were successfully matched in each group, and the curative effect of surgery was compared between the two groups.ResultsThere was no statistical difference in the type of surgery, intraoperative complications, postoperative complications, and hospital stay between the two groups (P>0.05). The operative time of the group A was significantly longer than that of the group B (P=0.023). There was no statistical difference between the two groups in postoperative recurrence (P=0.741).ConclusionThe operative time in overweight patients is significantly longer than that in the non-overweight patients, but it has no effect on the surgical outcomes and complications.
Objective To compare and analyze the occurrence of acute and chronic pain after subxiphoid and transcostal thoracoscopic extended thymectomy. MethodsA retrospective analysis was performed on 150 patients who underwent thoracoscopic extended thymectomy in our hospital from July 2020 to June 2022, among whome 30 patients received subxiphoid video-assisted thoracic surgery, and 120 patients received transcostal video-assisted thoracic surgery. The patients were matched by the propensity score matching method. Postoperative pain was evaluated by numeric rating scale (NRS). The intraoperative conditions and postoperative pain incidence were compared between the two groups. ResultsAfter matching, 60 patients were enrolled, 30 in each group, including 30 males and 30 females with an average age of 50.78±12.13 years. There was no difference in the general clinical data between the two groups (P>0.05), and no perioperative death. There were statistical differences in the intraoperative blood loss, postoperative drainage volume, postoperative catheter duration, postoperative hospital stay, postoperative pain on 1 d, 2 d, 3 d, 7 d, 3 months and 6 months after the surgery (P<0.05), but there was no statistical difference in the operation time or the postoperative 14 d NRS score (P>0.05). Further univariate and multivariate analyses for postoperative chronic pain showed that surgical method and postoperative 14 d NRS score were risk factors for chronic pain at the 3 months and 6 months after the surgery (P<0.05). Conclusion The subxiphoid thoracoscopic extended thymectomy has advantages over transcostal thoracoscopic surgery in the postoperative acute and chronic pain.
Objective To investigate the clinical effect of the DaVinci robot system and laparoscopic radical gastrectomy. Methods Propensity score matching and retrospective cohort study were adopted. Data of 446 patients who underwent robotic or laparoscopic radical gastrectomy in the Department of Gastrointestinal Surgery, Xijing Hospital, the First Affiliated Hospital of Air Force Military Medical University from January 2014 to April 2021 were collected. Among them, 174 cases underwent robotic and 272 cases underwent laparoscopic surgery. Using the method of propensity score matching, 133 cases were selected from robotic operation group and laparoscopic operation group respectively as the research object. The perioperative indexes of the two groups were compared. Kaplan-Meier survival analysis was used to draw the survival curve and calculate the survival rate. Cox regression model was used to analyze the risk factor of prognosis. Results There was no significant difference in baseline data between the robotic surgery group and the laparoscopic surgery group after propensity score matching (P>0.05). The operative time of the two groups [(236.47±50.32) min vs. (230.64±44.51) min, t=1.000, P=0.318], the number of lymph nodes dissected [(23.32±6.58) vs. (23.95±6.03), t=–0.826, P=0.410], the time of first anal exhaust [(3.46±0.77) days vs. (3.38±0.75) days, t=0.882, P=0.378], and the length of postoperative hospital stay [(6.98±2.84) days vs. (6.94±3.61) days, t=0.094, P=0.925] were similar, the differences were not statistically significant. Compared with the laparoscopic surgery group, the robotic surgery group had less intraoperative bleeding [(83.76±58.23) mL vs. (116.54±58.58) mL, t=–4.577, P<0.001], but the total hospitalization expenses was higher [(10.04±1.92) ten-thousand Yuan vs. (6.80±1.27) ten-thousand Yuan, t=16.211, P<0.001]. The incidence of postoperative complications between the two groups (χ2=0.057, P=0.812) and Clavien-Dindo classification of complications (Z=–0.440, P=0.965) were similar between the two groups, the differences were not statistically significant. The 3-year survival situation was similar between the two groups (P=0.356). Body mass index [RR=0.803, 95%CI (0.698, 0.924), P=0.002], TNM-staging [Ⅱ -stage vs.Ⅰ -stage, RR=4.152, 95%CI (1.121, 15.385), P=0.033; Ⅲ -stage vs.Ⅰ -stage, RR=5.476, 95%CI (1.458, 20.558), P=0.012] and postoperative complications [with vs. without, RR=3.262, 95%CI (1.283, 8.293), P=0.013] were prognostic factors for 3-year survival. Conclusion Compared with laparoscopic radical gastrectomy, robotic radical gastrectomy has the same short-term and long-term prognosis.
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.
ObjectiveTo evaluate the clinical outcomes of sutureless aortic valve replacement (SU-AVR) and transcatheter aortic valve implantation (TAVI) for aortic valve disease. MethodsWe conducted a computer-based search of databases including CNKI, WanFang Data, VIP, CBM, PubMed, The Cochrane Library, EMbase and Web of Science from the inception of the databases to March 2024. Two reviewers independently screened articles, extracted data and used the Cochrane bias risk assessment tool to evaluate the quality of the included studies. Meta-analysis was performed using Stata 18 software. ResultsThe included 17 studies using propensity-matched analysis consisted of 6 630 patients, including 3 319 patients in the SU-AVR group and 3 311 patients in the TAVI group. The SU-AVR group had lower mortality than the TAVI group at 1-year ［RR=0.58, 95%CI(0.38, 0.87), P=0.009］, 2-year ［RR=0.61, 95%CI(0.43,0.85), P=0.004］ and 5-year ［RR=0.63, 95%CI(0.50,0.79), P=0.000］. The SU-AVR group had a significantly lower rate of new permanent pacemaker implantation (PPI) ［RR=0.75, 95%CI(0.58, 0.98), P=0.037］, moderate-to-severe paravalvular leak (PVL) ［RR=0.20, 95%CI（0.12, 0.32）, P=0.000］, myocardial infarction(MI)［RR=0.30, 95%CI (0.11,0.80), P=0.017］, more-than-mild residual aortic regurgitation (AR)［RR=0.29, 95%CI（0.17, 0.48）, P=0.000］. In addition, the SU-AVR group had a higher postoperative mean aortic gradient [SMD=0.39, 95%CI (0.17, 0.62), P=0.000］than the TAVI group. Conclusion The early and mid-term clinical outcomes of SU-AVR were superior compared to TAVI.
ObjectiveTo explore the clinical efficacy of single-branch intraoperative stent combined with modified bilateral cerebral perfusion in type A aortic dissection. MethodsA retrospective analysis was conducted on the clinical data of patients who underwent surgery for type A aortic dissection at the First Affiliated Hospital of Anhui Medical University from January 2021 to May 2024. Patients were divided into the experimental group (single branch stent combined with modified bilateral cerebral perfusion) and the control group (traditional surgical method, straight stent+unilateral cerebral perfusion) according to the surgical method. Propensity score matching analysis was used to match the two groups of patients with a ratio of 1:1, and the perioperative data and clinical efficacy after matching were compared. ResultsA total of 14 patients were included in the experimental group, including 13 males and 1 female, with an average age of (47.4±16.1) years. There were 56 patients in the control group, including 38 males and 18 females, with an average age of (52.1±11.7) years. After propensity score matching, 14 patients were included in each group. Compared with the control group, the ventilator support time [(27.4±24.3) h vs. (93.4±88.0) h, P=0.018], length of stay in the intensive care unit [(2.8±1.8) d vs. (8.7±6.5) d, P=0.009], and postoperative awakening time [(5.4±2.2) h vs. (8.8±4.8) h, P=0.047] in the experimental group were shorter than those in the control group, with statistically significant differences. ConclusionSingle-branch intraoperative stent combined with modified bilateral cerebral perfusion can effectively shorten ventilator support time, length of stay in the intensive care unit, and postoperative awakening time, and is safe and effective for the treatment of type A aortic dissection, which is worth further promotion.
ObjectiveTo evaluate the safety and medium-to-long-term efficacy of Maze procedure with cryoablation in conjunction with mitral valve surgery for atrial functional mitral regurgitation (AFMR). MethodsRetrospective collection of clinical data from patients undergoing surgical treatment for AFMR in the Department of Cardiovascular Surgery at General Hospital of the Northern Theater Command from June 2013 to February 2022. Patients were divided into an ablation group and a non-ablation group based on whether they underwent ablation. Propensity score matching analysis was performed on the two groups with 15 parameters as covariates. The safety and medium-to-long-term efficacy of the operation in the two groups were compared. ResultsA total of 167 patients with AFMR were included, 95 of whom underwent isolated mitral valve surgery (non-ablation group), and 72 of whom underwent Maze procedure with cryoablation in conjunction with mitral valve surgery (ablation group). A total of 72 pairs were successfully matched. The ablation group included 33 males and 39 females, with an average age of (59.39±6.38) years; the non-ablation group included 33 males and 39 females, with an average age of (60.94±8.95) years. Within an average follow-up of 4 years, 4 deaths occurred in the ablation group, and 13 in the non-ablation group. The duration of extracorporeal circulation [(152.14±35.24) min vs. (93.63±32.48) min] and aortic cross-clamping time [(81.22±20.30) min vs. (47.26±17.89) min] were significantly longer in the ablation group compared to the non-ablation group (P<0.001), but there was no statistical difference in the incidence of perioperative adverse events between the two groups (P>0.05). The diameters of the left atrium and left ventricle were significantly reduced in both groups compared to pre-operation (P<0.05); the postoperative diameter of the left atrium [(47.82±6.72) mm vs. (51.58±8.63) mm] and left ventricular end-diastolic diameter [(47.46±5.06) mm vs. (49.61±6.64) mm] in the ablation group were significantly smaller than those in the non-ablation group, with statistical differences (P<0.05). At each follow-up time point, the sinus rhythm conversion rate and drug-free rate in the ablation group were significantly higher than those in the non-ablation group (P<0.001). Kaplan-Meier analysis showed that the cumulative survival rate in the ablation group (2 years: 98.6% vs. 89.9%; 4 years: 91.7% vs. 87.7%; 6 years: 91.7% vs. 73.9%, 8 years: 91.7% vs. 67.2%; P=0.026) and the rate of freedom from rehospitalization for heart failure (2 years: 98.3% vs. 86.7%; 4 years: 95.8% vs. 82.8%; 6 years: 90.1% vs. 74.9%; 8 years: 81.1% vs. 57.2%; P=0.031) were significantly higher than the non-ablation group. ConclusionConcomitant cryoablation Maze procedure with mitral valve surgery in treating patients with AFMR is safe and has satisfactory results. It can effectively promote the recovery of sinus rhythm, reverse adverse cardiac remodeling, and reduce the incidence of medium-to-long-term adverse events.
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.
ObjectiveTo evaluate the value of postoperative radiotherapy (PORT) in patients with stage ⅢA-N2 non-small cell lung cancer who received complete resection and chemotherapy. MethodsPatients with stage ⅢA-N2 non-small cell lung cancer who received complete resection and chemotherapy were chosen from the SEER Research Plus Database [17 Registries, November 2012 Submission (2000-2019)]. The patients were divided into a PORT group and a non-PORT group according to whether the PORT was used. To balance baseline characteristics between non-PORT and PORT groups, R software was used to conduct a propensity score matching (PSM) with a ratio of 1 : 1 and a matching tolerance of 0.01. Both the Cox regression analysis and Kaplan-Meier survival analysis were conducted to evaluate the value of PORT in terms of overall survival (OS) and disease-specific survival (DSS). ResultsIn total, 2468 patients with stage ⅢA-N2 non-small cell lung cancer were enrolled, including 1078 males and 1390 females with a median age of 65 (58-71) years. There were 1336 patients in the PORT group, and 1132 patients in the non-PORT group. Cox regression analysis showed that PORT was not significantly associated with OS (multivariate analysis: HR=1.051, 95%CI 0.949-1.164, P=0.338) and DSS (multivariate analysis: HR=1.094, 95%CI 0.976-1.225, P=0.123). No statistical difference was found in the OS or DSS between non-PORT group and PORT group after PSM analysis (P＞0.05). ConclusionPORT does not have a survival benefit for patients with stage ⅢA-N2 non-small cell lung cancer who received complete resection and chemotherapy.
