Objective To review and summarize the surgical techniques and their outcomes for the treatment of lumbar spondylolysis in young patients by direct surgical repair. Methods Both home and abroad literature on the surgical techniques and their outcomes respectively for the treatment of lumbar spondylolysis in young patients by direct surgical repair was reviewed extensively and summarized. Results Direct surgical repair of lumbar spondylolysis can offer a simple reduction and fixation for the injured vertebra, which is also in accord with normal anatomy and physiology. In this way, normal anatomy of vertebra can be sustained. As reported surgical techniques of direct repair, such as single lag screw, hook screw, cerclage wire, pedicle screw cable, pedicle screw rod, and pedicle screw hook system, they all can provide acceptable results for lumbar spondylolysis in young patients. Furthermore, to comply strictly with the inclusion criteria of surgical management and select the appropriate internal fixation can also contribute to a good effectiveness. Within the various methods of internal fixation, pedicle screw hook system has been widely recognized. Conclusion Pedicle screw hook system fixation is simple and safe clinically. With the gradual improvement of this method and the development of minimally invasive technologies, it will have broad application prospects.
Objective To summarize the effectiveness of modified surgical repair for severe ingrown toenail. Methods Between January 2005 and December 2010, 13 patients with severe ingrown toenail (16 toes) were treated. There were 12 males (15 toes) and 1 female (1 toe), aged 18-32 years with an average of 20 years. The disease duration was 1-15 years (mean, 2 years and 9 months). All affected toes were great toes. Ingrown toenail occurred bilaterally in 3 cases and unilaterally in 10 cases. Granulation tissue surrounding nail-edge, embedded toenail, and necrotic nail bed were completely removed; tension glue was used to make wound edge close to nail bed. Results At 3-5 days after operation, wound congestion, swelling, and exudation were improved; at 7 days, new nail bed formed; at 2 weeks, all wounds healed, and nail bed was epitheliogenic, wound edge healed well close to nail plate, and patients returned to normal life. At 6 months after nail extraction, new toenail grew and nail groove formed. No recurrent sign was found during 24-month follow-up. Conclusion Modified surgical repair is one of effective methods to treat severe ingrown toenail with the advantages of good appearance and low recurrent rate.
Objective To investigate the effectiveness and surgical skills of microsurgical repair of radial nerve deep branch injury. Methods Between March 2001 and February 2011, 49 cases of radial nerve deep branch injury were treated by microsurgical technique. There were 40 males and 9 females with an average age of 32 years (range, 19-58 years), including 13 cases of knife-cut injury, 9 cases of electric-saw injury, 7 cases of dagger-stab injury, 6 cases of glass-cut injury, 5 cases of iatrogenic injury, 4 cases of Monteggia fracture, 3 cases of nailgun injury, and 2 cases of crush injury of the forearm complicated by fracture of the proximal radius. The disease duration ranged from 3 hours to 3 years and 8 months (mean, 4.9 months). The sites of injury were at front of supinator tube in 15 cases, in the supinator tube in 23 cases, and at back of supinator tube in 11 cases. One-stage repair was performed by end-to-end suture in 21 cases, including 9 cases of epineurial neurorrhaphy and 12 cases of perineurial neurorrhaphy; two-stage repair was performed in 28 cases, including 26 cases of sural nerve graft and 2 cases of neurolysis. Results Postoperative wounds primarily healed. All patients were followed up 21.5 months on average (range, 12-39 months). At last follow-up, in 21 cases of one-stage repair, the muscle strength of the extensor pollicis longus was level 5 in 13 cases, and level 4 in 8 cases; in 28 cases of two-stage repair, the muscle strength of the extensor pollicis longus was level 5 in 2 cases, level 4 in 21 cases, level 3 in 4 cases, and level 2 in 1 case; and significant difference was found (Z= — 5.340, P=0.000). In 9 cases undergoing epineurial neurorrhaphy at one-stage repair, the muscle strength of the extensor pollicis longus was level 5 in 3 cases, and level 4 in 6 cases; in 12 cases undergoing perineurial neurorrhaphy at one-stage repair, the muscle strength of the extensor pollicis longus was level 5 in 10 cases, and level 4 in 2 cases; and significant difference was found (Z= — 2.279, P=0.023). In 26 cases undergoing nerve graft at two-stage repair, the muscle strength of the extensor pollicis longus was level 5 in 2 cases, level 4 in 20 cases, level 3 in 3 cases, and level 2 in 1 case; in 2 cases undergoing neurolysis at two-stage repair, the muscle strength of the extensor pollicis longus was level 4 in 1 case and level 3 in 1 case; and no significant difference was found (Z= — 1.117, P=0.264). According to the upper arm function assessment criterion issued by Hand Surgery Association of Chinese Medicine Association, the results were excellent in 18 cases, good in 3 cases in one-stage repair patients; excellent in 2 cases, good in 21 cases, fair in 4 cases, and poor in 1 case in two-stage repair patients; and there was significant difference (Z= — 5.340, P=0.000). Conclusion Microsurgical one-stage repair of radial nerve deep branch injury can obtain better effectiveness than two-stage repair by nerve graft, and perineurial neurorrhaphy is significantly better than epineurial neurorrhaphy.
Objective To analyze the effectiveness and advantages of the microsurgical repair of flexor tendon rupture with non-knot Kessler suture method in anastomotic stoma by comparing with the method of traditional Kessler suture. Methods Between February 2005 and February 2010, 122 patients (163 fingers with 243 flexor digital tendons) with flexor tendon rupture, were treated with microsurgical repair by non-knot Kessler suture method (treatment group); flexor tendon was sutured, and sodium hyaluronate was used to repair tendon membrane, tendon sheaths, and the tissue surroundingtendons. The cl inical data were analysed, and were compared with ones from 96 patients (130 fingers with 186 flexor digital tendons) with flexor tendon rupture treated with traditional Kessler suture between February 2001 and February 2005 (control group). There was no significant difference in gender, age, cause of injury, injury site, duration, and other general information between 2 groups (P gt; 0.05). Kleinert elastic traction therapy (dynamic-protection) was performed at 3 weeks after surgery, and the finger function exercise was done after 24 hours. Results Infection of incision occurred in 2 cases of the treatment group and in 5 cases of the control group, and were cured after 2 weeks of dressing change; the other incisions healed by first intention. The patients were followed up 6 to 14 months (mean, 9 months). In the treatment group, the total active movement (TAM) was (192.0 ± 13.1)°; the results were excellent in 54 cases, good in 58 cases, moderate in 8 cases, and poor in 2 cases with an excellent and good rate of 92%. In the control group, TAM was (170.0 ± 15.2)°; the results were excellent in 23 cases, good in 30 cases, moderate in 22 cases, and poor in 21 cases with an excellent and good rate of 55%. Significant difference in TAM was found between 2 groups (P lt; 0.01). Conclusion The microsurgical repair of flexor tendon with non-knot Kessler suture method in anastomotic stoma with repair of tendon membrane, tendon sheaths, and the tissue surrounding tendons is more effective than the traditional Kessler suture, but long-term effectiveness still needs further observation.
Objective To study the mid-facial development characteristics of the goats with cleft palate after in-utero surgical repair at different stages. Methods Twenty-four Boer hybrid female goats were selected, aged from 8 to 12 months and weighing from 35 to 55 kg. The mating day was designated for 0 day. At 30 days, pregnant was confirmed by B-ultrasound test, and the goats were divided into 5 groups (experimental groups 1, 2, 3, 4, and normal control group). Twenty pregnant goats of 4 experimental groups (n=5) were injected DL-anabasine (15 mg/day) from 31 to 42 days to establish cleft palate model of fetal lamb, 4 pregnant goats of normal control group used as controls without injection. At pregnant 65, 90, and 120 days, cleft palate was repaired in the uterus in experimental groups 1, 2, and 3, while cleft palate was not repaired in experimental group 4. After 1 month of birth, the maxillary bone width (posterior premolar morphological measurement, PPMM) and the maxillary bone length (anterior premolar morphological measurement, APMM) were measured with CT scanning. The dry skull of goats were harvested for gross observation. Results There was no significant difference in PPMM and APMM between experimental group 1 and the normal control group (P gt; 0.05), but there were significant differences between experimental groups 1 and 4 (P lt; 0.05) at 1 month after birth. Significant differences were oberved in PPMM and APMM between experimental group 2 and normal control group, experimental group 4 (P lt; 0.05). There were significant differences in PPMM between experimental group 3 and normal control group, experimental group 4 (P lt; 0.05), in APMM between experimental group 3 and normal control group (P lt; 0.05). Five goats with cleft palate in experimental group 4 died at 1-2 months after birth. Conclusion At pregnant 65 days, in-utero surgical repair of cleft palate has less influences on mid-facial development. The earlier repair is performed, the higher risk of miscarriage was.
Objective To compare the effects of transthoracic device closure and surgical closure on ventricular septal defect systemically. Methods A systematic literature search was conducted using the PubMed, EMbase, The Cochrane Library, VIP, CNKI, CBM, Chinese Clinical Trial Register, ClinicalTrials. gov and Wanfang Database up to July 31, 2016. Quality was assessed and data of included articles were extracted. The meta-analysis was conducted using RevMan 5.0 and Stata 14.0 software. Results Eleven studies were identified, including 5 RCTs and 6 cohort studies involving 2 504 patients. For success rate, there was no statistical difference between the transthoracic closure group and the surgical closure group in RCT (RR=0.99, 95%CI 0.96 to 1.03, P=0.70); the success rate in the transthoracic closure group was lower than that in the surgical closure group in the cohort study (OR=0.21, 95%CI 0.08 to 0.55, P=0.002). Both results of RCTs and cohort studies showed that compared with surgical closure, transthoracic device closure reduced duration of the operation (RCT MD=–79.38, 95%CI –95.00 to –63.76, P<0.000 01; cohort studyMD=–66.26, 95%CI –71.20 to –61.31, P<0.000 01) and hospital stay (RCTMD=–2.10, 95%CI –2.65 to –1.55, P<0.000 01; cohort studyMD=–3.99, 95%CI –6.03 to –1.94, P=0.000 1), and the patients with blood transfusion (RCT RR= 0.04, 95%CI 0.01 to 0.11, P<0.000 01; cohort studyOR=0.01, 95%CI 0.00 to 0.13, P=0.001). In the transthoracic closure group the risk of postoperative arrhythmia reduced (RCT RR=0.20, 95%CI 0.13 to 0.32, P<0.000 01; cohort studyOR=0.46, 95%CI 0.31 to 0.67, P<0.000 1). In the transthoracic closure group a higher postoperative valvular regurgitation risk in RCT induced (RR=1.45, 95%CI 1.07 to 1.96, P=0.02) and the rate of postoperative valvular regurgitation in cohort study reduced (OR=0.43, 95%CI 0.20 to 0.92, P=0.03). However, there was no statistical difference in postoperative residual shunt (RCT RR=0.96, 95%CI 0.57 to 1.62, P=0.89; cohort study OR=0.52, 95%CI 0.12 to 2.25, P=0.38). Conclusion Transthoracic device closure can shorten duration of the operation, hospital stay and reduce the patients with blood transfusion and post- and intraoperative arrhythmia risk. Therefore, transthoracic device closure may be a better approach for some ventricular septal defect patients.
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.
ObjectiveTo summarize the application and clinical effect of left anterior minimally invasive thoracotomy to surgical repair of subarterial ventricular septal defect (VSD) in children.MethodsFrom October 2015 to April 2019, 21 children with subarterial VSD underwent surgical repair via left anterior minimally invasive thoracotomy. There were 13 males and 8 females, aged 5-13 (9.1±2.2) years, and weighing 22-55 (35.6±9.5) kg. The diameter of subarterial VSD was 4-15 (9.1±3.3) mm. Eight patients had right coronary valve prolapse, and 4 aortic valve regurgitation (3 mild and 1 mild-to-moderate). The minimally invasive surgery was performed via left parasternal thoracotomy through the second or third intercostal space. The peripheral perfusion was performed with femoral arterial and venous cannulation. After aortic cross-clamp (ACC), subarterial VSD was performed with direct suture of patch closure through an incision on the root of pulmonary artery.ResultsAll patients successfully underwent surgical repair (patch closure, n=15; direct suture, n=6) of subarterial VSD through left anterior minimally invasive thoracotomy. The cardiopulmonary bypass time was 45-68 (57.1±6.3) min. The ACC time was 23-40 (32.6±4.7) min. The postoperative ventilation time was 5-9 (6.3±1.3) h, postoperative in-hospital time was 5-8 (5.7±1.0) d and drainage volume was 33-105 (57.5±17.7) mL in postoperative 24 h. No death, residual VSD shunt, atrioventricular block, wound infection or thoracic deformity occurred during the perioperation or follow-up. Only one patient still had trivial aortic valve regurgitation.ConclusionLeft anterior minimally invasive thoracotomy could be safely and effectively applied to surgical repair of subarterial VSD in children, with satisfactory early- and mid-term outcomes.
ObjectiveTo investigate effectiveness and safety of right vertical infra-axillary thoracotomy (RVIAT) in surgical repair for intra-cardiac anomalies combined with patent ductus arteriosus (PDA).MethodsWe retrospectively analyzed the clinical data of 34 patients who underwent intra-cardiac correction of congenital heart defects and PDA ligation simultaneously via RVIAT in our hospital from August 2014 to August 2019. There were 25 males and 9 females with an age range of 0.5-6.1 years.ResultsThe length of incision was 3.0 (3.0, 3.5) cm. The operation time lasted 110.0 (90.0, 121.0) min. The cardiopulmonary bypass time was 45.5 (38.8, 63.5) min and the aortic cross-clamp time was 22.5 (14.8, 34.8) min. The bleeding volume was 20.0 (13.8, 20.0) mL. ICU stay time was 17.0 (5.5, 22.3) h, post-operative mechanical ventilation time was 4.0 (2.0, 6.0) h, total in-hospital cost was 46 (39, 51) thousand yuan. There was no mortality or reoperation during perioperative and follow-up period. Within the median follow-up of 636.0 days, 1 patient had minimal residual ventricular septal defect shunt while no new-onset scoliosis, funnel chest or pectus carinatum was detected. No bilateral mammary developmental asymmetry was observed in the female patients during the follow-up period. All the patients’ parents or guardians were satisfied with the right vertical infra-axillary aesthetic skin incision.ConclusionThe minimally invasive repair for intra-cardiac heart defects combined with PDA via RVIAT is a safe and effective method with minimal invasiveness and excellent cosmesis.
ObjectiveTo explore the early outcomes of the surgical treatment for patent ductus arteriosus (PDA) combined with intracardiac abnormities via right vertical infra-axillary thoracotomy (RVIAT).MethodsA total of 7 children with PDA combined with intracardiac defects underwent surgery through RVIAT at the Second Affiliated Hospital of Nanjing Medical University from 2016 to 2018. There were 4 males and 3 females, with an average age of 5.3±4.5 years and weight of 18.0±11.2 kg.ResultsIn all patients, PDA was ligated before the repair of intracardiac abnormities. No patient died in hospital. All patients were followed up, with a mean follow-up time of 18.0±8.0 months. No other complications such as residual shunts, arrhythmias, hemorrhaging or wound infection occurred after operations or during the follow-up period.ConclusionRVIAT is an emerging technique used for the surgical repair of PDA combined with intracardiac defects. It yields satisfying cosmetic results, without increasing postoperative complications or mortality.
