The experiment performed on domestic pig, was designed to investigate the architecture of the stretching skin and the effect of tension traction on the wound closure. An 7 cm x 3.5 cm was drawn at a standard position. Drawing horizontal and vertical lines on the traction area, points of 1 cm apart were tattooed on the lines. A traction force measuring device was used to draw the wound edges together. Measurements of the distances between the points were made. An 7 cm x 10 cm wound was made on identical sites of each hind leg. In the experiment the traction tension was applied on the edges of wound immediately after the wound debridement. The results showed the stretched distance in the two areas was 5-7 times the width of the wound. The gain of skin from traction was 61-89 percent in the width of the wound. The wounds from traction five days could be closed 5 days after traction. It was concluded that the skin which could be used for traction was abundant. Wound closure with the skin traction technique had many advantages, such as rapid decreasing the size of wound and early closing of wound.
ObjectiveTo evaluate the value of incision closure device in laparoscopic cholecystolithotomy. MethodsThe clinical data of 130 patients underwent laparoscopic cholecystectomy from Oct. 2014 to Feb. 2015 were retrospectively analyzed. According to the methods of gallbladder suture, 130 cases were divided into two groups, 72 cases underwent traditional manual suture (MS group), and 58 cases underwent incision closure device (ICD group). The operative time, postoperative gastrointestinal function recovery time, bleeding volume, postoperative hospitalization time, hospitalization expenses, complications, and postoperative 6-12 months follow-up of patients in 2 groups were observed.Results One hundred and thirty cases were performed laparoscopic cholecystolithotomy successfully. The operative time and postoperative gastrointestinal function recovery time of ICD group were significantly shorter than those of MS group, the difference was statistically significant (P < 0.05). The hospitalization expenses of the patients in ICD group were significantly higher than those in the MD group (P < 0.05). There were no significant difference between the two groups in the bleeding volume and postoperative hospital stay (P > 0.05). The patients were followed up for 6-12 months, with an average of 8 months, and no complications occurred and stone recurrence. ConclusionIncision closure device can shorten the time of laparoscopic cholecystolithotomy and postoperative recovery of gastrointestinal function, but the cost is higher. Next development, still need decrease the expend and strengthen clinical promotion.
ObjectiveTo compare the lamina cribrosa parameters between primary open angle glaucoma (POAG) and chronic primary angle closure glaucoma (CPACG) eyes. MethodsA total of 73 POAG eyes (73 subjects), 64 CPACG eyes (64 subjects), and 40 normal control eyes (40 subjects) with matched ages were included in this cross-sectional observational study. No significant difference was found in sex (χ2=2.07) and age (F=0.38) among three groups (P > 0.05). The intraocular pressure, average retinal nerve fiber layer (RNFL) thickness and average visual field defect were not significantly different between POAG and CPACG patients (F=15.67, 21.15, 44.40, 27.99; P < 0.05). All subjects underwent spectral-domain optical coherence tomography (SD-OCT) with enhanced depth imaging (EDI). The optic nerve head was scanned radially at the angle of 20; six high resolution B-scan images were obtained from each eye. The center and para-center lamina cribrosa thickness (LCT) and anterior lamina cribrosa surface depth (ALCSD) were measured in each image. The mean LCT and ALCSD were recorded as the average of the LCT and ALCSD of the 6 images and compared among POAG, CPACG and normal control eyes. ResultsThe average LCT of normal control eyes were (211.48±12.07) μm, while those of the POAG eyes were (145.43±34.33) μm, CPACG eyes were (156.79±33.66) μm. The mean LCT of the POAG and CPACG eyes were thinner than those of the control eyes (t=-11.76, -9.88; P < 0.01). All LCT of the POAG eyes were significantly thinner than those of the CPACG eyes (t=-1.96, P=0.03).The average ALCSD of normal control eyes were (390.73±84.40) μm, while those of the POAG eyes were (558.51±176.66) μm, CPACG eyes were (539.39±177.30) μm, respectively. The average ALCSD of the POAG and CPACG eyes were deeper than those of the control eyes (t=5.65, 4.96; P < 0.01). But no significantly different ALCSD was shown between POAG and CPACG eyes (t=0.63, P=0.49). ConclusionsPOAG and CPACG eyes have thinner LCT and deeper ALCSD than normal eyes. POAG eyes have thinner LCT than CPACG eyes when their visual field defect and damage of RNFL were in the same degree.
Objective To analyze the safety and effectiveness of ultrasound-guided thoracoscopic atrial septal defect (ASD) closure. Methods We prospectively collected the clinical data of 12 patients with ASD treated by ultrasound-guided thoracoscopic ASD closure in Fuwai Hospital from January to September 2017. The characteristics of the patients' ASD and operation, operation safety and effectiveness, postoperative complications and follow-up results were analyzed. Results Among the 12 patients, 10 were successfully treated with ultrasound-guided thoracoscopic ASD closure. Two patients switched to ASD repair under thoracoscopy-assisted cardiopulmonary bypass. The size of the ASD was 17-40 (27.22±8.97) mm and the size of the occluder was 36 (30-42) mm. The average postoperative length of hospital stay was 6 days. There were no complications such as arrhythmia, bleeding and pericardial effusion after operation. The average follow-up was 6 (3-10) months after the operation. During the follow-up, no Ⅲ-degree conduction block, occluder dislocation, residual shunt or cardiac pericardial effusion was found. Conclusion Ultrasound-guided thoracoscopic ASD closure is a minimally invasive, safe and effective treatment. This technique provides a new minimally invasive surgical option for patients with large defect diameter and poor edge condition.
OBJECTIVE To introduce the technique of epiphysiolysis and epiphysis grafting in the treatment of early partial closure of the epiphysial plate in children, and evaluate its effect. METHODS Retrospective study was performed in 10 cases of cubitus varus and valgus, or genu varum and valgum due to early partial closure of the epiphysial plate, 6 cases received simple cuneiform osteotomy, and 4 cases received epiphysioloysis and epiphysis grafting. RESULTS Clinical outcoming after 6-month to 5-year’s follow-up showed 1 case deformity of recurrence and 2 cases of non-isometric limb after simple osteotomy, while no recurrence and isometric limb after epiphysiolysis and epiphysis grafting. CONCLUSIONEpiphysiolysis and epiphysis grafting may effectively prevent the recurrence of postoperative deformity, and restore the longitudinal growth of limb.
Objective To explore the effectiveness of cyanoacrylates (Fuaile) for spinal subdural benign tumorectomy to prevent the cerebrospinal fluid leakage. Methods Between January 2009 and March 2013, 35 patients underwent spinal subdural benign tumorectomy. Of 35 patients, Fuaile and gelatin sponge were used after stitch suture for a watertight closure of the dura in 19 cases (trial group), and only gelatin sponge was used after stitch suture in 16 cases (control group). There was no significant difference in gender, age, disease duration, types of tumors, and sites of tumors between 2 groups (P gt; 0.05). The ratio of watertight closure, incision healing, and relative complications were compared between 2 groups. Results All patients in 2 groups achieved watertight closure of the dura intraoperatively. There was no significant difference in operation time, intraoperative blood loss, length of dura incision, hospitalization time, total drainage volume, and drainage time between 2 groups (P gt; 0.05). Primary incision healing was obtained; no delayed healing, infection, or nerve compression occurred in all patients. At last follow-up, the ratios of successful watertight closure of trial and control groups were 89.5% (17/19) and 50.0% (8/16) respectively, showing significant difference (P=0.02). No delayed cerebrospinal fluid leakage or incision infection was found at 1 and 3 months after operation. Conclusion The application of cyanoacrylates for watertight closure of dura in spinal subdural benign tumorectomy is safe and effective.
Objective To systematically evaluate the safety and efficacy of percutaneous closure of atrial septal defect (ASD) guided by echocardiography alone versus fluoroscopy. Methods The databases of PubMed, The Cochrane Library, EMbase, VIP, Wanfang Data and CNKI from January 2000 to October 2021 were searched by computer for relevant research literature. Two reviewers independently screened the literature, extracted the data and evaluated the quality according to the inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.4 software. Results A total of 19 cohort studies and 1 randomized controlled study were collected, including 2 825 patients. The Newcastle-Ottawa Scale score for cohort studies was≥7 points. Meta-analysis showed that there was no statistical difference in the operative success rate (RR=1.01, 95%CI 1.00 to 1.02, P=0.17), incidence of occluder displacement/shedding (RR=0.77, 95%CI 0.26 to 2.27, P=0.63), incidence of arrhythmia (RR=0.50, 95%CI 0.21 to 1.14, P=0.10), incidence of pericardial effusion (RR=0.98, 95%CI 0.32 to 2.98, P=0.97), operative time (MD=–0.23, 95%CI –7.56 to 7.10, P=0.95) or cost (SMD=–0.39, 95%CI –1.09 to 0.30, P=0.27) between the two groups. The echocardiography group reduced the incidence of total postoperative complications (RR=0.42, 95%CI 0.30 to 0.60, P<0.001) and residual shunt (RR=0.70, 95%CI 0.50 to 0.98, P=0.04), and shortened length of hospital stay (MD=–0.43, 95%CI –0.77 to 0.09, P=0.01). Conclusion Compared with traditional fluoroscopy-guided percutaneous closure of ASD, echocardiography guidance alone is equivalent in terms of operative success rate, major postoperative complications, operative time and total cost, but it reduces the incidence of total postoperative complications and residual shunt, and has a shorter length of hospital stay.
ObjectiveTo evaluate the mid-term safety, efficacy and feasibility of perventricular device closure for subarterial ventricular septal defect.MethodsClinical data of 97 patients diagnosed with subarterial ventricular septal defect through echocardiography in West China Hospital from September 2013 to December 2015 were retrospectively analyzed. There were 66 males and 31 females aged 3 (1.8, 5.9) years. All the patients underwent perventricular device closure under the guidance of transesophageal echocardiography using eccentric occlusion device. Possible complications such as residual shunt, valvular regurgitation, atrioventricular conduction block and arrhythmias were recorded during the 1-year, 3-year and 5-year follow-up.ResultsAll the patients received perventricular device closure successfully except that 1 patient underwent open surgical repair under cardiopulmonary bypass 3 months later because of the migration of device. So the rate of complete closure was 99.0%. No residual shunt, moderate or severe valvular regurgitation, atrioventricular conduction block or arrhythmias were observed 5 years later.ConclusionTreating subarterial ventricular septal defect through perventricular device closure exhibits remarkable mid-term efficacy, safety and feasibility with high success rate.
Objective To evaluate the safety and efficacy of primary closure (PC) and T-tube drainage (TD) after laparoscopic common bile duct exploration (LCBDE). Methods The randomized controlled trials of PC and TD after LCBDE were retrieved from the Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until April 2015. All calculations and statistical tests were performed using ReviewerManager 5.2 software. Results Both of the two groups had no postoperative deaths within 30 days. The operative time and hospital stay of PC gourp were shorter than TD group statistically〔OR=–24.76, 95CI (–29.21, –20.31),P<0.000 01〕and〔OR=–2.68, 95%CI (–3.69, –1.67),P<0.000 01〕. The reoperative rate of PC group was lower than that of TD group, and the difference was statistically significant〔OR=0.20, 95%CI (0.05, 0.81),P=0.02〕. There was no significant difference between the two groups in the occurrence of postoperative severe complications〔OR=0.54, 95%CI (0.26, 1.12),P=0.10〕. Conclusions Compared with the TD group, the operative time and hospitalization time are shorer in PC group, and complication rate is similar, but the cost of treatment of the TD group is higher than PC group, so after LCBDE a primary closure of common bile duct is safe and effective method.
ObjectiveTo observe the differences in scleral lamina curvature (SLC) of patients with pseudoexfoliation glaucoma (PXG), primary open-angle glaucoma (POAG), and primary chronic angle-closure glaucoma (CPACG) were compared and analyzed and their significance was analyzed.MethodsA retrospective clinical study. From June 2017 to December 2020, 30 PXG (PXG group), POAG (POAG group) and CPACG patients (CPACG group) diagnosed at Eye Center of Cangnan County people's Hospital of Zhejiang Province (Cangnan Hospital Affiliated to Wenzhou Medical University) were included in the study. The age difference between the three groups of patients was statistically significant (t=17.925, P=0.001); gender composition ratio (χ2=2.158, P=0.276), intraocular pressure (t=4.993, P=0.078), and axial length (t=1.956, P=0.532), central corneal thickness (t=1.407, P=0.724), average visual field defect (t=2.725, P=0.496), optic disc retinal nerve fiber layer thickness (t=2.185, P=0.492) in comparison, the differences were not statistically significant (P＞0.05). The frequency-domain optical coherence tomography deep-enhanced imaging (OCT EDI) technology was used to measure the average and 0°, 30°, 60°, 90°, 120°, 150° SLC of the affected eyes, and calculate the SLC index (SLCI) and SL curve depth (SLCD). Quantitative data comparison between groups used independent sample t test. Count data comparison used χ2 test. Univariate and multivariate logistic regression analysis were used for correlation analysis.ResultsThe results of OCT EDI examination showed that the SLC of eyes with PXG and CPACG was significantly steep, while the SLC of eyes with POAG was relatively flat. Except for the angle of 150°, the other 6 angles of SLCI and SLCD in the PXG group and CPACG group were higher than those in the POAG group, and the differences were statistically significant (P＜0.05). However, there was no statistically significant difference between PXG group and CPACG group for 7 angles of SLCI and SLCD (P＞0.05). Logistic regression analysis showed that the average SLCI [odds ratio (OR)=1.498, 95% confidence interval (CI) 1.137-2.018, P=0.001], age (OR=1.074, 95%CI 1.019-1.143, P=0.016) was significantly correlated with PXG; mean SLCI (OR=1.625, 95%CI 1.192-1.997, P=0.001), intraocular pressure (OR=1.383, 95%CI 1.106-1.993, P=0.012) was significantly correlated with CPACG. POAG group (β=0.143, 95%CI 0.032-0.208, P=0.016), CPACG group (β=0.132, 95%CI 0.079-0.315, P=0.043) intraocular pressure was correlated with mean SLCI; all factors of PXG group were correlated with SLCI without correlation (P＞0.05).ConclusionCompared with POAG, the SLC of eyes with PXG and CPACG is steeper and related to disease occurrence.
