Objective:The aim of this study was to evaluate the safety and efficacy of prostatistic urethral lift (PUL) in treating benign prostate hyperplasia(BPH) through systematic review and Meta-analysis.Methods:A systematic literature search on CNKI, Wanfang, VIP, PubMed, Web of Science, Cochrane Library and Chinese Clinical Trial Registry to identify the relevant studies and data before September 2021. Information was extracted from each eligible article. All statistical analyses of this Meta-analyses were performed with Review Manager 5.3 and Stata 15.0 software to conduct a Meta-analysis of the symptom improvement of BPH patients before and 3 months and 12 months after PUL. The main evaluation indicators included: International Prostate Symptom Score (IPSS), maximum urinary flow rate (Q max), post-void residual (PVR), and Quality of Life Scale (QOL), Sexual Health Inventory for Men (SHIM). The complication rate of PUL was systematically evaluated. Results:A total of 12 clinical studies were included, and 850 patients accepted the PUL. The results showed that IPSS decreased significantly at both 3 and 24 months after PUL surgery ( MD = -11.77, 95% CI -12.47—-11.07, P<0.05; MD = -9.71, 95% CI-10.76—-8.66, P<0.05), Q max (ml/s) increased to a certain degree ( MD = 3.87, 95% CI 3.37—4.37, P<0.05; MD = 3.68, 95% CI 2.97—4.40, P<0.05), QOL decreased significantly ( MD=-2.57, 95% CI -2.76—-2.38, P<0.05; MD = -2.14, 95% CI -2.38—-2.91, P<0.05), SHIM score was unaffected ( P>0.05), compared with preoperative baseline data. PUL could be performed under local anesthesia, the main perioperative complications reported in the included studies were dysuria (17%±6%), hematuria (14%±5%) and pelvic pain (8%±6%), all of which were transient. Conclusions:PUL in the treatment of BPH has significant short-term and long-term efficacy with low surgical risk and complication rate, and can preserve normal ejaculation function. It is a safe and effective minimally invasive surgery, which can be used for BPH patients with intolerance to general anesthesia surgery or normal sexual function demand.

To analyse the clinical data of reoperations in congenital heart disease and discuss the management strategy of reoperation for congenital heart disease.
 Methods: We retrospectively studied the clinical data for patients underwent reoperation in congenital heart disease in Cardiovascular Surgery, Second Xiangya Hospital, Central South University from January 2007 to December 2015. Demographic and operative details, in-hospital mortality and major postoperative complications were analysed.
 Results: A total of 8 647 congenital heart disease surgery procedures were performed, including 147 (1.7%) reoperations. Among the patients, residual septal defect repair (30 cases, 20.4%), planed staged operation (28 cases, 19.0%), and Fontan procedure (20 cases, 13.6%) were the most common kinds of reoperation. In addition, 140 (95%) operations were through repeat sternotomies, 144 (98%) patients underwent operation with cardiopulmonary bypass, and 100 (68%) with cardiac arrest. Cardiopulmonary bypass and aortic cross clamp were maintained for 21-447 (135.5±87.8) minutes and 0-202 (49.9±49.7) minutes. There were 10 in-hospital deaths with a total mortality of 6.8%. The major complications included low cardiac output syndrome (24 cases, 16.3%), renal dysfunction (7 cases, 4.8%), respiratory insufficiency (14 cases, 9.5%), unplanned reoperations for drainage of haemorrhagic cardiac tamponade (4 cases), and delayed sternal closure (2 cases).
 Conclusion: Repeat sternotomy is the main way of reoperation, but it is not a major risk for operative mortality and morbidity. Improving the management of complex malformation, standardizing the follow-up, choosing the right timing of surgery, and reducing surgical complications will help reduce the risk of reoperation.

OBJECTIVES: The integrated model of prenatal diagnosis and postnatal treatment for congenital heart disease (CHD) leads to an increasing number of operation in infants. This study aims to reveal the risk factors for postoperative early mortality and delayed recovery in infants less than 3 months old, who underwent surgical treatment for CHD in the Department of Cardiovascular Surgery, Second Xiangya Hospital, Central South University during the past 5 years. METHODS: Clinical variables were collected via medical records. Delayed recovery was defined as the time of postoperative intubation, or cardiac intensive cure unit (CICU) stay, or hospital stay longer than its third quartile. Risk factors for early postoperative prognosis and the odds ratio (OR) were analyzed with logistic regression analysis. RESULTS: A total of 511 infants underwent surgical treatment for CHD from January 2016 to June 2020 were retrospectively reviewed, including 217 (42.5%) infants with complex CHD. The median age was 60 days (3 hours-90 days); and median weight was 4.5 (1.7- 8.4 kg). There were 26 postoperative mortalities, making the incidence at 5.1%, including 5 (5/294, 0.7%) mortalities in patients with uncomplicated CHD, and 21 (9.6%) mortalities in patients with complex CHD. Based on multivariable analysis, risk factors for postoperative mortality were diagnosis of complex CHD (OR=5.53, P<0.001), weight under 4.0 kg (OR=9.86, P<0.001), preoperative symptoms (OR=3.17, P=0.012), and emergency operation (OR=11.66, P<0.001). The median time for postoperative intubation, CICU stay, and hospital stay were 21.0 (0.3-979.0) hours, 3.0 (0.5-91.0) days, and 11.5 (3.0-105.0) days, respectively. A total of 177 (34.6%) infants delayed recover, with risk factors including diagnosis of complex CHD (OR=3.41, P=0.001), weight under 4.0 kg (OR=4.55, P<0.001), and preoperative symptoms (OR=3.91, P<0.001). CONCLUSIONS Surgical treatment for infants (<3 months) with CHD is still a challenge, particularly for infants with complex CHD and weight under 4.0 kg. We can improve the prognosis of CHD treatment in infants by establishing the integrated model of prenatal diagnosis and postnatal treatment to choose the most suitable time window, avoid symptoms before surgery, and reduce emergency operation.

OBJECTIVES: Due to the lack of large-sized pulmonary valved conduit products in clinical practice, hand-sewn expanded polytetrafluoroethylene (ePTFE) valved conduit has been used for right ventricular outflow tract (RVOT) reconstruction in many heart centers around the world. This study aims to summarize the early results of the ePTFE valved conduit and the sewing technology of the conduit in combination with the latest progress, and to provide a reference for the application of ePTFE valved conduit. METHODS: A total of 21 patients using ePTFE valved conduit for RVOT reconstruction in the Second Xiangya Hospital, Central South University from October 2018 to October 2020 were prospectively enrolled in this study. The age at the implantation of the conduit was 4.3 to 43.8 (median 15.1) years old, with weight of (38.9±4.1) kg. In this cohort, 14 patients underwent re-reconstruction of RVOT, including 12 patients with pulmonary regurgitation at 6.3 to 31.0 (median 13.8) years after tetralogy of Fallot (TOF) repair, and 2 patients with failed bovine jugular vein conduit (BJVC). Seven patients underwent Ross operations. Among them, 3 were for aortic valve stenosis, 2 were for aortic regurgitation, and 2 were for both stenosis and regurgitation. The ePTFE valved conduits were standard hand-sewn during the surgery. The 3 leaflets were equal in size with arc-shaped lower edge of the valve sinus. The free edge of the valve leaflets was straight with the length of about 1 mm longer than the diameter. The height of the valve sinus was 4/5 of the diameter. The junction of the valve leaflet was 3/4 of the height of the sinus. The designed leaflets were then continuous non-penetrating sutured into the inner surface of Gore-Tex vessel to make a valved conduit. Valved conduits with diameter of 18, 20, and 22 mm were used in 2, 9, and 10 cases, respectively. The surgical results, postoperative recovery time, and serious complications were summarized, and the changes of postoperative cardiac function status and hemodynamic status of the conduits were investigated. RESULTS: During the implantation of ePTFE valved conduit for RVOT reconstruction, 2 patients underwent mechanical mitral valve replacement with Ross operation, 2 patients with pulmonary regurgitation with repaired TOF underwent left and right pulmonary artery angioplasty, and 1 patient with failed BJVC underwent tricuspid valvuloplasty. The cardiopulmonary bypassing time for patients underwent re-reconstruction of RVOT was (130.9±16.9) min, with aorta clamping for 1 patient to repair the residual defect of the ventricular septum. The cardiopulmonary bypassing and aorta clamping time for Ross operation were (242.7±20.6) min and (145.6±10.5) min, respectively. The duration of postoperative ventilator assistance, intensive care unit stay, and hospital stay were 3.5 h to 7.7 d (median 17.1 h),11.2 h to 29.5 d (median 1.9 d), and 6.0 to 56.0 (median 13.0) d, respectively. All patients survived after discharge from hospital. The follow-up rate after discharge was 100% with median time at 15.0 (13.0 to 39.0) months. No death happened during the follow-up. One patient underwent stent implantation due to right coronary stenosis 2 months after Ross operation. One patient underwent balloon dilation due to right pulmonary artery ostium stenosis 1 year after re-reconstruction of RVOT. The cardiac function of all patients recovered to NYHA class I 6 months after operation. The peak pressure gradient across the valve measured by transthoracic echocardiography before discharge was (9.4±2.6) mmHg (1 mmHg=0.133 kPa), and (18.3±6.1) mmHg at the last follow-up. There was no significant increase in the gradient during the follow-up (P=0.134). No patient suffered from mild or more pulmonary regurgitation. CONCLUSIONS Hand-sewn ePTFE valved conduit is feasible for RVOT reconstruction. It is a promising material for RVOT reconstruction which can effectively meet clinical need. In our experience, the ePTFE valved conduit is simple to manufacture with satisfactory early outcomes.In the application of ePTFE valved conduit, attention should be paid to implantation indications and postoperative anticoagulation management, especially to the preparation details of the valved conduit, to obtain better function and durability of the conduit after implantation.
