摘要:目的:分析微創外科室間隔缺損(ventricular septal defect,VSD)封堵失敗原因,以期提高術前超聲心動圖篩查水平。方法:回顧性分析25例微創外科VSD封堵失敗改行修補術病例,對比超聲表現及手術所見,歸納總結產生并發癥的原因。結果:殘余分流與VSD假性膜部瘤右室面具有多個出口和低估VSD大小密切相關;VSD合并主動脈瓣右冠瓣脫垂是主動脈瓣反流的主要原因;封堵器移位與低估VSD大小且使用偏心封堵器有關;原有三尖瓣反流加重和發生Ⅲ度房室傳導阻滯VSD均位于隔瓣下方;封堵失敗組較封堵成功組缺損偏大,差異具有統計學意義(Plt;0.05)。結論:超聲心動圖對VSD及其毗鄰結構的細致評估,有助于嚴格適應證,提高手術成功率。 Abstract: Objective:To analyze the failure of perventricular closure of ventricular septal defect (VSD), in order to improve the preoperative echocardiography examination. Methods: Twentyfive cases underwent surgical repair after failure of perventricular closure of VSD were included in this study. With combination of echocardiographic and surgical findings, retrospective analysis of the failure of perventricular closure of VSD were attempted to summarize the cause of complications.Results: Residual ventricular communication was due to underestimation of size of VSD and pseudomembranous aneurysm resulting in multiple outlets of VSD on the right ventricle side; preoperative prolapse of rightcoronary cusp was the main reason for mild or greater than mild aortic valve regurgitation after eccentric device closure of VSD; Underestimation of the size of VSD and using eccentric occluder device were responsible for the displacement of VSD occluder device. Postoperative aggravated tricuspid regurgitation and Ⅲ°atrialventricular block (AVB) were attributed to VSDs located under the septal leaflet of tricuspid valve. The size of VSD in group of failed perventricular device closure of VSD was larger than that in group of successful device closure of VSD,and the difference was significant(Plt;0.05). Conclusion: Echocardiography vividly reveals VSD and adjacent structures, which should be used in accessing the anomaly and defect and formulating surgical plans to reduce surgical morbidity and mortality.
How to effectively repair esophageal fistulas, caused by esophageal perforation, rupture and anastomotic leakage after esophagectomy has always been a key problem for the digestive surgeon. Although there are many clinical treatment methods, the therapeutic effect is still completely unsatisfactory, especially when severe mediastinal purulent cavity infection is associated with the esophageal fistula. In recent years, foreign centers have promoted a new minimally invasive endoscopic treatment technology to repair the esophageal fistula, endoscopic vacuum-assisted closure therapy, with significantly curative effect. In this article, we will review the specific operation, advantages and disadvantages, as well as the clinical efficacy of endoscopic vacuum-assisted closure therapy in treating the esophageal fistulas, to provide a new therapeutic technique for esophageal fistulas and expand the new field of minimally invasive endoscopic therapy.
ObjectiveTo investigate the application value and research progress of PST technique in preventing anastomotic leakage after rectal cancer surgery. MethodThe related literatures at home and abroad in recent years about the application of left colon artery preservation, suture of anastomotic stoma and closure of pelvic floor peritoneum, and indwelling anal canal （PST technology for short） in rectal cancer surgery were searched and summarized. ResultsPST technology could prevent anastomotic leakage after rectal cancer surgery from many angles, reduce infection and inflammation, promote postoperative rehabilitation and improve the quality of life of patients, and it is simple and easy to do. The great advantages of PST technology are gradually verified and recognized in clinic. ConclusionPST is a safe and feasible method to prevent anastomotic leakage and relieve the symptoms of anastomotic leakage.
Objective To explore the feasibility of transcatheter closure of congenital heart disease (CHD) under the guidance of transthoracic echocardiography (TTE). Methods A total of 37 patients with CHD who received transcatheter closure under the guidance of transthoracic echocardiography from November 2013 through November 2015 in our hospital were recruited. There were 15 males and 22 females, aged 1 to 16 years. Among them 32 patients suffered atrial septal defect and 5 patients had patent ductus arteriosus. The transcatheter closure of CHD was performed under the guidance of TTE. The patients underwent echocardiography follow-up at one, three and six months after surgery. Results Closure devices were successfully implanted in 37 patients under TTE guidance. The procedure was simple and safe. During the follow-up, no severe complication such as valvular injury, pericardial effusion, residual shunt and peripheral vascular injury occurred. Conclusion Transcatheter closure of CHD under TTE guidance is a feasible method and worth further clinical application.
ObjectiveTo summarize the nursing experience of vacuum-assisted closure (VAC) technology for deficiency of skin and soft tissue in "4·20" earthquake damage. MethodsWe used VAC to treat 20 patients suffering from deficiency of skin and soft tissue who were injured in "4·20" earthquake (35 wounds) from April 21st to 28th, 2013; and we observed closely the results of nursing for pain and psychological care. ResultsA total of 35 wounds were all cleaned after 5 to 7 days; 20 wounds were healed after VAC treatment; 15 wounds recovered well by covering autogenous split-thickness skin; 20 patients had stable emotion and all left the hospital with the recovery. ConclusionVAC for deficiency of skin and soft tissue caused by "4·20" earthquake damage may obviously decrease the time of wound healing, relieve the pain caused by changing fresh dressing, and reduce the length of stay in the hospital.
ObjectiveTo compare the effects of transthoracic device closure and traditional surgical repair on atrial septal defect systemically.MethodsA systematic literature search was conducted using the PubMed, EMbase, The Cochrane Library, VIP, CNKI, CBM, Wanfang Database up to July 31, 2018 to identify trials according to the inclusion and exclusion criteria. Quality was assessed and data of included articles were extracted. The meta-analysis was conducted by RevMan 5.3 and Stata 12.0 software.ResultsThirty studies were identified, including 3 randomized controlled trials (RCTs) and 27 cohort studies involving 3 321 patients. For success rate, the transthoracic closure group was lower than that in the surgical repair group (CCT, OR=0.34, 95%CI 0.16 to 0.69, P=0.003). There was no statistical difference in mortality between the two groups (CCT, OR=0.43, 95%CI 0.12 to 1.52, P=0.19). Postoperative complication occurred less frequently in the transthoracic closure group than that in the surgical repair group (RCT, OR=0.30, 95%CI 0.12 to 0.77, P=0.01; CCT, OR=0.27, 95%CI 0.17 to 0.42, P<0.000 01). The risk of postoperative arrhythmia in the transthoracic closure group was lower than that in the surgical repair group (CCT, OR=0.56, 95%CI 0.34 to 0.90, P=0.02). There was no statistical difference in the incidence of postoperative residual shunt in postoperative one month (CCT, OR=4.52, 95%CI 0.45 to 45.82, P=0.20) and in postoperative one year (CCT, OR=1.03, 95%CI 0.29 to 3.68, P=0.97) between the two groups. Although the duration of operation (RCT MD=–55.90, 95%CI –58.69 to –53.11, P<0.000 01; CCT MD=–71.68, 95%CI –79.70 to –63.66, P<0.000 01), hospital stay (CCT, MD=–3.31, 95%CI –4.16, –2.46, P<0.000 01) and ICU stay(CCT, MD=–10.15, 95%CI –14.38 to –5.91, P<0.000 01), mechanical ventilation (CCT, MD=–228.68, 95%CI –247.60 to –209.77, P<0.000 01) in the transthoracic closure group were lower than those in the traditional surgical repair group, the transthoracic closure costed more than traditional surgical repair during being in the hospital (CCT, MD=1 221.42, 95%CI 1 124.70 to 1 318.14, P<0.000 01).ConclusionCompared with traditional surgical repair, the transthoracic closure reduces the hospital stay, shortens the length of ICU stay and the duration of ventilator assisted ventilation, while has less postoperative complications. It is safe and reliable for patients with ASD within the scope of indication.
Doubly committed sub-arterial ventricular septal defect (VSD) is a unique type of VSD which is located beneath both the aortic and pulmonary valve. Open-heart repair is traumatic especially for pediatric patient while trans-catheter device closure is also not suitable for this type of VSD. Minimally invasive per-ventricular device closure has been introduced as an alternative method in the treatment of doubly committed VSD with encouraging results. In the review, we will illustrate the surgical technique as well as perioperative management strategy as for this technique in treating doubly committed VSD.
ObjectiveTo investigate the effectiveness of self-made limb chronic wound closure device in the treatment of scarred lower limbs and complex skin and soft tissue defects.MethodsBetween January 2014 and January 2017, 29 patients with complex fractures of the lower extremities and skin and soft tissue defects were treated. There were 19 males and 10 females with an average age of 31.1 years (range, 21-66 years). The causes of injury included 14 cases of traffic accidents, 5 cases of falling from height, 4 cases of heavy object crushing injury, 4 cases of mechanical crushing injury, and 2 cases of exposed steel plate after fracture. There were 26 cases of calf fracture and skin defect, 3 cases of metatarsal bone fracture and skin defect of the foot. The skin defect ranged from 5 cm×3 cm to 18 cm×8 cm. The time from injury to admission was 5-31 days, with an average of 14.3 days. All patients underwent a thorough debridement, open wound drainage, self-made chronic wound closure device combined with Ilizarov stretching technique for a slow skin and soft tissue traction. After the wound was cleaned up and the granulation tissue was freshened, the skins on both sides were closed, and then proceed to the second stage operation of skin grafting or direct suture closure based on the size of the wound.ResultsAll patients were followed up 8-20 months, with an average of 13 months. Twenty-nine patients were treated with self-made chronic wound closure device combined with Ilizarov technique for 1-2 times with an average of 1.3 times, then the wound infection was controlled and the granulation tissue grew well. In the course of treatment, the pain was not obvious and the patients had good compliance. All patients’ wounds healed clinically without skin traction complications and formed linear or flaky scars.ConclusionThe self-made chronic wound closure device is effective in repairing complex scarred wounds of lower extremities, and it is easy to operate.
ObjectiveTo systematically review the efficacy and safety of phacoemulsification combined with trabeculectomy versus simple phacoemulsification for primary angle closure glaucoma with cataract.MethodsDatabases including PubMed, EMbase, The Cochrane Library, CBM, CNKI, VIP and WanFang Data were searched to collect randomized controlled trials (RCTs) about phacoemulsification combined with trabeculectomy vs. simple phacoemulsification for primary angle closure glaucoma with cataract from inception to May 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was conducted by RevMan 5.3 software.ResultsA total of eight studies involving 679 patients were included. The results of meta-analysis showed that: there were no significant differences between two groups in postoperative visual acuity (MD=0.00, 95%CI –0.10 to 0.09, P=0.98), postoperative anterior chamber depth (MD=0.14, 95%CI –0.17 to 0.45, P=0.37) and adverse reactions rates (optic nerve injury: RR=1.56, 95%CI 0.70 to 3.47, P=0.28; visual field defect: RR=1.43, 95%CI 0.70 to 2.92, P=0.33; corneal edema: RR=0.57, 95%CI 0.25 to 1.32, P=0.19).ConclusionCurrent evidence shows that phacoemulsification combined with trabeculectomy and simple phacoemulsification has the similar efficacy and safety for primary angle closure glaucoma with cataract. Due to limited quantity and quality of the included studies, the above conclusions still need to be verified by more high quality studies.
ObjectiveTo study effect of different surgical treatments for patent ductus arteriosus in children.MethodA total of 38 patients with patent ductus arteriosus who underwent surgical treatment of cardiothoracic surgery between January 2016 and December 2017 in our hospital were as an observation group (12 patients with severing suture, 26 patients with ligation, 14 males and 24 females, aged 0.08–8.67 years). In the same period, 38 patients with patent ductus arteriosus who underwent interventional closure in the Department of Cardiology were as a control group (17 males and 21 females, aged 0.50–5.42 years). The clinical effectiveness of the two groups was compared.ResultsThe operation time, postoperative hospital stay, and blood transfusion rate in the observation group were higher than those in the control group with statistical differences (P<0.05). There was no statistical difference in intraoperative blood loss and complications between the two groups.ConclusionsIn patients with a single patent ductus arteriosus or a small catheter, interventional closure of the patent ductus arteriosus is less trauma and faster recovery. But in patients with lower weigh, premature, other intracardiac malformations, large catheter, moderate or severe pulmonary hypertension, the surgery is better.
