ABSTRACT
Objective:The purpose of this study was to investigate the clinical value of CT-guided localization of pulmonary nodules with soft wire hook-wire by trailing technique.Methods:The clinical data of 211 pulmonary nodules of 185 patients from November 2020 to March 2022 in Beijing Aerospace General Hospital were retrospectively analyzed. The pulmonary nodules were localized with soft wire hook-wire by trailing technique before video-assisted thoracic surgery (VATS). The success rate, complications, pathological results and localization operations related data were statistically analyzed.Results:The success rate of localization was 97.63% (206/211), and the success rate of VATS removal was 99.53% (210/211). The average operation time was (7.19 ± 2.62) min, and the average time required for resection of lesions was 27 min (10 to 126 min). During the surgery, the soft wire hook-wire of two patient was found to be dislocated and retracted into the chest wall. The pulmonary nodules were successfully located and removed according traces left by puncture points on the lung surface. It was found that the hook-wire was located in the interlobar fissure in 3 patients. The pulmonary nodules were successfully removed by the hook-wire position and appropriately expanding the resection range. A minor pneumothorax occurred in 49 patients, but no closed drainage was needed; 12 patients developed intrapulmonary hematoma; 15 patients with chest pain were treated with analgesia.Conclusions:For small pulmonary nodules requiring thoracoscopic surgery, the computed tomography-guided pulmonary nodule localization with soft wire hook-wire by trailing technique is more convenient, safe and effective, and is worthy of promotion to use.
ABSTRACT
Objective@#To explore the relationship between isochronous substitution and BMI, waist circumference (WC), and body fat rate (FAT) among physical activity (PA), sedentary (SB), and sleep (SLP), so as to provide effective measures for obesity control in adolescents.@*Methods@#A total of 193 adolescents aged 12-15 (90 males and 103 females) was randomly selected, and their height, weight, and BMI were measured using routine testing methods from May to August 2022. The PA, SB and SLP of the participants were measured using a 3D accelerometer (ActiGraph GT3X+).@*Results@#The arithmetic mean value overestimated SLP (40.8%) and SB (39.6%) to some extent, and underestimated LPA (16.1%) and MVPA (3.5%) to some extent. Based on the ISM at 15 min, MVPA was substituted for other activity, BMI Z decreased by 0.17-0.22 units, WC Z decreased by 0.16-0.20 units, and FAT Z decreased by 0.17-0.22 units. The substitution between MVPA and for other activity exhibited significant asymmetry. The effects of MVPA substitutions for SB was the largest, followed by the effects of MVPA substitutions for SLP, and the effects of MVPA substitutions for LPA was the lowest. As MVPA substitutions for other behaviors, it reached its maximum (0.06-0.08 units ) when the MVPA time increased by 5 minutes.@*Conclusions@#MVPA plays an irreplaceable role in the control of adolescent obesity . While reducing SB time, MVPA duration should be increased to ensure that the daily MVPA duration is not less than 55 minutes in order to effectively control obesity.
ABSTRACT
Central venous lesion is a difficult problem in the vascular access complications of hemodialysis, which can cause serious clinical symptoms and affect the quality of hemodialysis and life of patients. We established arteriovenous fistula of the contralateral graft blood vessel with the used vein on the diseased side of the central vein of the patient. The arteriovenous fistula of the graft blood vessel was successfully punctured and hemodialysis was performed 2 weeks later. In this way, we not only solved the problem of venous hypertension and subsequent vascular access in the patient, but also reserved more vascular resources.
ABSTRACT
Objective To investigate the effect of the amputation order of pulmonary artery and pulmonary artery on pulmonary residual blood volume in total thoracoscopic lobectomy.Methods Sixtyeight patients who were scheduled to underwent total thoracoscopic lobectomy from June 2015 to April 2019 in Beijing Aerospace General Hospital were selected.The patients were divided into first amputation pulmonary artery group and first amputation pulmonary vein group by random envelope method with 34 cases in each group.Five cases in first amputation pulmonary artery group and 4 cases in first amputation pulmonary vein group were excluded because of the procedure modification or the fragmentation of the specimen during the course of operation.In the end,29 cases were enrolled in first amputation pulmonary artery group and 30 cases in first amputation pulmonary vein group.In first amputation pulmonary vein group,all arteries were ligated before interruption of the veins;and in first amputation pulmonary artery group had a reverse sequence.The perioperative period status were recorded,and the crude pulmonary quality,dry pulmonary quality,pulmonary residual blood volume and adjusted pulmonary residual blood ratio were measured or calculated.Results All 59 patients were operated successfully.No serious complications occurred,no perioperative death occurred,and no patients needed blood transfusion.There was no statistical difference in the incidence of minor complications between first amputation pulmonary artery group and first amputation pulmonary vein group:27.6％ (8/29) vs.33.3％ (10/30),P＞0.05.There were no statistical differences in operative time,transoperative bleeding volume,pulmonary residual blood volume,crude pulmonary quality,dry pulmonary quality,adjusted pulmonary residual blood ratio,hemoglobin difference before and after surgery,postoperative drainage time and postoperative hospitalization time between 2 groups (P＞0.05).Conclusions The amputation order of pulmonary artery and pulmonary vein sequence of vessel interruption during total thoracoscopic lobectomy has no effect on the pulmonary residual blood volume,can be reasonably selected according to the intraoperative situation.
ABSTRACT
Objective To assess the choice between direct operation and followed- up observation for subclinical esophageal submucosal mass. Methods The clinical data of 133 patients with subclinical esophageal submucosal mass from February 1996 to October 2013 were retrospectively analyzed. The patients were divided into 2 groups according to the modes of intervention: direct operation group (82 cases) and followed-up group (51 cases). Their clinical data, imaging, endoscopy information, modes of intervention and final outcome were compared. Results All of the 133 patients were considered as esophageal leiomyoma. The age and body examination detection rate in direct operation group were significantly lower than those in followed-up group: (47.7 ± 13.1) years vs. (52.2 ± 10.1) years and 15.9% (13/82) vs. 37.3% (19/51), the tumor diameter, case history and incidence of chest and abdominal pain were significantly higher than those in followed-up group: (2.2 ± 1.4) cm vs. (1.7 ± 1.0) cm, 51 (44, 60) months vs. 47 (40, 55) months and 28.0% (23/82) vs. 9.8% (5/51), and there were statistical differences (P＜0.05 or ＜0.01). There was no operative mortality in direct operation group, and the incidence of mild surgical complication was 8.5% (7/82); the pathological result showed that esophageal leiomyoma and other benign diseases were in 70 cases, and malignant disease in 12 cases (12 cases of malignant diseases who missed diagnosis before operation were mostly caused by incomplete examination.). In followed-up group, the mean observation time was 35.5 (3 to 240) months, disease progression was in 23 cases (45.1%, 23/51), 3 cases developed new-onset symptoms, 20 cases increased in diameter, and the average doubling time was 856 (126 to 2 891) d. Twenty-seven patients eventually underwent surgery (52.9%, 27/51, post-observation intervention group), without perioperative death, and the incidence of surgical complication was 7.4% (2/27). The pathological result showed that esophageal leiomyoma and other benign diseases were in 23 cases, and malignant disease in 4 cases. Compared with direct operation group, post-observation intervention group had no delayed treatment due to the observation and did not increase the surgery risk and difficulty, and no malignant transformation occurred. Conclusions Subclinical esophageal submucosal mass could be followed up, but endoscopic ultrasonography, CT and gastrointestinal angiography must be performed and must be followed up closely.
ABSTRACT
Objective To evaluate the clinical outcomes of hemodialysis patients after superficial femoral artery - superficial femoral vein arteriovenous graft (AVG). Methods Hemodialysis patients with mid - thigh superficial femoral artery - superficial femoral vein AVG from August 2015 to March 2018 in department of vascular surgery, Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine were enrolled. Their clinical outcomes and complications after operation were analyzed retrospectively. Patency rates were measured by Kaplan - Meier survival curve. Results A total of 18 cases were enrolled. The success rate of the operation was 100％without complication. Follow - up time was (22.00 ± 11.77) months with 100％ follow - up rate. The 6 months -, 12 months -, 24 months - primary patency rates were 83.3％±8.8％, 48.5％±12.1％, 24.2％± 13.5％, respectively; secondly patency rates were 100.0％, 100.0％, 87.5％±11.7％. There were 1 case of seroma, 1 case of puncture site infection, 11 cases of stenosis and 5 cases thrombosis during follow-up, while no heart failure, ischemia or pseudoaneurysm. Conclusion Mid - thigh AVG has low infection rate and high patency rate, so it can be as the first choice for the lower extremity AVG in hemodialysis patients.
ABSTRACT
Objective To summarize the experiences of aneurysmorrhaphy for arteriovenous fistula aneurysms with acute thrombosis in hemodialysis patients.Methods There were 7 cases of arteriovenous fistula with acute thrombosis from Nov 2015 to Feb 2017 at our department of vascular surgery,Longhua Hospital.Results In all cases thrombosis was secondary to proximal stenosis or occlusion.The stenosis and occlusion were corrected with embolectomy and aneurysmorrhaphy.The proximal part of the cephalic vein was translocated to the basilic vein in 1 case,axillary vein in 2 cases;autologous vein graft in 1 case;resection of the occlusion,end-to-end anastomosis in 1 case;autogenous patch in 1 case.No perioperative complications occurred.The operation site was cannulated within one month after operation in all cases.Patients were followed up for 7 months to 23 months,all cases were patent.Conclusions Aneurysmorrhaphy is effective,reliable and safe for arteriovenous fistula aneurysms with acute thrombosis in hemodialysis patients.
ABSTRACT
BACKGROUND@#Localization of multiple small lung nodules is the technical difficulty of minimally invasive operation resection. However, there are few clinical studies on the preoperative localization of multiple small lung nodules. This study was designed to evaluate the clinical value of preoperative computed tomography (CT) guided microcoil localization for multiple small lung nodules compared with single small lung nodule before video-assisted thoracoscopic surgery (VATS).@*METHODS@#A retrospective analysis of the clinical data of 235 patients with preoperative pulmonary nodules microcoil localization was performed. According to whether the nodules were single, they were divided into single nodule group (184 cases) and multiple nodules group (51 cases) (multiple nodules group). The single nodule group was positioned under CT-guided conventional methods. The multiple nodules group were CT guided localized by microcoil in batches according to priority before VATS. The success rate, complications, pathological results and localization operations related data were statistically analyzed.@*RESULTS@#The success rate of localization in multiple nodule groups was 90.2%, there was no significant difference compared with the single nodule group (90.2% vs 94.6%, P=0.205). The occurrence rate of pneumothorax in multiple nodule group and single nodule group was no statistical difference (21.6% vs 14.1%, P=0.179), however, the operation time in the multiple nodule group was significantly longer than the single nodule group [(30.6±6.6) min vs (19.9±7.4) min, P=0.000]. There were no serious complications such as massive hemoptysis, air embolism or hemothorax. There was no conversion to thoracotomy due to failure of localizing the nodules during operation. Sub-lobectomy was the main method of operation. The majority of postoperative pathologies were non-invasive carcinomas.@*CONCLUSIONS@#For multiple small lung pulmonary nodules requiring thoracoscopic surgery, according to certain strategies, preoperative CT-guided localized by microcoil in batches according to priority before VATS is safe and effective, and worthy of promotion.
