Objective To analyze the excision of accessory navicular with reconstruction of posterior tibial tendon insertion on navicular for the treatment of flatfoot related with accessory navicular and to evaluate its effectiveness. Methods Between May 2006 and June 2011, 33 patients (40 feet) with flatfoot related with accessory navicular were treated. There were 14 males (17 feet) and 19 females (23 feet) with an average age of 30.1 years (range, 16-56 years). All patients had bilateral accessory navicular; 26 had unilateral flatfoot and 7 had bilateral flatfeet. The disease duration ranged from 7 months to 9 years (median, 24 months). The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-midfoot score was 47.9 ± 7.3. The X-ray films showed type II accessory navicular, the arch height loss, and heel valgus in all patients. All of them received excision of accessory navicular and reconstruction of posterior tibial tendon insertion on navicular with anchor. Results All patients got primary wound heal ing without any compl ication. Thirty patients (36 feet) were followed up 6-54 months with an average of 23 months. All patients achieved complete pain rel ief at 6 months after surgery and hadgood appearance of the feet. The AOFAS ankle-midfoot score was 90.4 ± 2.0 at last follow-up, showing significant difference when compared with preoperative score (t=29.73, P=0.00). X-ray films showed that no screw loosening or breakage was observed. There were significant differences in the arch height, calcaneus incl ination angle, talocalcaneal angle, and talar-first metatarsal angle between pre-operation and last follow-up (P lt; 0.01). Conclusion The excision of accessory navicular with reconstruction of posterior tibial tendon insertion on navicular is a good choice for the treatment of flatfoot related with accessory navicular, with correction of deformity, excellent effectiveness, and less complications.
【Abstract】 Objective To investigate the feasibility of transpositional anastomosis of C4 anterior trunk and accessory nerve for functional reconstruction of the trapezius muscle so as to provide theoretical basis of repairing accessory nerve defects. Methods Thirty-six adult male Sprague-Dawley rats (weighing 200-250 g) were randomly divided into the experimental group (n=18) and control group (n=18). The transpositional anastomosis of C4 anterior trunk and accessory nerve was performed in the left sides of experimental group; the accessory nerve was transected in the left sides of control group; and the right sides of both groups were not treated as within-subject controls. The electrophysiological and histological changes of the trapezius muscle were measured. The values of the latencies and amplitudes of compound muscle action potential (CMAP) were recorded in the experimental group at 1, 2, and 3 months; the latency delaying rate, amplitude recovery rate, and restoration rate of muscular tension were caculated. The counts of myelinated nerve fibers from distal to the anastomotic site were analyzed. The transverse area of the trapezius muscle was also measured and analyzed in 2 groups. Meanwhile, the muscles and nerves were harvested for transmission electron microscope observation in the experimental group at 1 and 3 months. Results As time passed by, the experimental group showed increased amplitudes of CMAP, shortened latencies of CMAP, and improved muscular tension. At 3 months, the amplitude recovery rates were 63.61% ± 9.29% in upper trapezius muscle and 73.13% ± 11.85% in lower trapezius muscle; the latency delaying rates were 130.45% ± 37.27% and 112.62% ± 19.57%, respectively; and the restoration rate of muscular tension were 77.27% ± 13.64% and 82.47% ± 22.94%, respectively. The passing rate of myelinated nerve fibers was 82.55% ± 5.00%. With the recovery of innervation, the transverse area of the trapezius muscle increased, showing significant differences between experimental group and control group at different time points (P lt; 0.05). The transmission electron microscope showed that the myotome arranged in disorder at 1 month and tended to order at 3 months. Conclusion Transpositional anastomosis of C4 anterior trunk and the accessory nerve can effectively reconstruct the function of the trapezius muscle of rats.
Objective To investigate the method of single umbilical port laparoscopic cholecystectomy and its feasibility. Methods The clinical data of 46 patients receiving single port umbilical laparoscopic cholecystectomy in this hospital from December 2008 to February 2009 were analyzed retrospectively. Results Fourty-six cases were operated successfully with ordinary laparoscopic instruments by single umbilical port laparoscopic cholecystectomy, all without drainage placed. Operative time was from 40 to 130 min, average 52.3 min; bleeding was from 10 to 150 ml, average 40.6 ml. No complications, such as biliary leakage, hemorrhage, umbilical hernia and infection of incisional wound happened. Postoperative abdominal wall scar was not obvious, 1-4 d hospitalization, from 2 weeks to 3 months following-up without disconnecting of incision. Conclusions The single umbilical port laparoscopic cholecystectomy is safe and feasible, with little abdominal wall scar, but difficult to perform, so it can be applied in hospitals with related conditions as improvements of laparoscopic cholecystectomy.
ObjectiveTo discuss the importance of early identification and effective management of puncture-associated complications after trans-radial percutaneous coronary procedures. MethodsA total of 698 patients undergoing trans-radial percutaneous coronary procedures from June to December 2012 were included and followed up. The puncture associated complications and their clinical managements were summarized in the present study. ResultsWe found that trans-radial approach was safe. The main puncture-associated complications included access-site pain, tension blisters and hemorrhagic complication. Complications with severe clinical consequence were rare. Most of the complications could be successfully treated with conservative management including access-site nursing and psychological nursing. ConclusionTrans-radial approach is safe for percutaneous coronary procedures, but close clinical monitoring and nursing are essential.
Objective To summarize the advantages and complications of implantation of venous access port via axillary vein in the operation of breast cancer, and to explore the countermeasures against the complications. Methods A total of 40 female patients with breast cancer were enrolled in this observational study between January 2011 and September 2014. They were aged from 32 to 62 years with a mean of 49.3 years. The time for implantation, catheter life, reasons for port removal and complications were evaluated. Results The average time for implantation was 23.3 minutes. The catheter life ranged from 142 to 917 days with a mean of 395 days. Four patients (10%) had port-related complications including 2 cases of pocket infection and 2 of catheter dysfunction. Thirty-one ports were removed for termination of chemotherapy, and four were removed for complications. Conclusions It is simple and time-saving to implant venous access port via axillary vein in the operation of breast cancer. The incidence of pocket infection is high, and is expected to be reduced by choosing appropriate cases and taking strict aseptic norms.
ObjectiveTo investigate and analyze the strategies for choosing venous access devices for critically ill patients. MethodsThe medical staffs in ICU were required to fulfill a questionnaire on the knowledge and application of venous access devices in critically ill patients in May 2015.A descriptive statistical analysis was carried out on the answers generated from the questionnaire using SPSS 19.0 software. ResultsA total of 50 questionnaires were distributed randomly and 46 valid questionnaires were recovered.The effective response rate was 92.0%.The proportion of junior, intermediate and senior medical staffs was 80.4%, 13.0% and 6.6%, respectively.The proportion of doctors and nurses was 39.1% and 60.9%, respectively.The average seniority was (5.7±4.9)years.The proportion of ICU medical staffs who were acquainted with PIV, ACVC, PICC, TCVC, PORT and Midline was 100.0%, 100.0%, 100.0%, 69.6%, 43.5% and 13.0%, respectively.The proportion of ICU medicial staffs who would take the styles of drug, the time of treatment, the patients' condition and the costs into consideration when choosing venous access devices was 100.0%, 100.0%, 64.0% and 18.0%, respectively.91.3% and 39.1% of ICU medical staffs would choose PIV and ACVC respectively if the time of treatment was less than 1 week.56.5%, 69.6% and 26.1% of ICU medical staffs would choose PIV, ACVC and PICC respectively if the time of treatment was between 1 and 4 weeks.30.4%, 39.1%, 82.6% and 32.6% of ICU medical staffs would choose PIV, ACVC, PICC and PORT respectively if the time of treatment was more than 4 weeks.52.2% of ICU medical staffs were acquaint with the styles and the indication of antibiotic coating central venous catheter.The main reasons for infusion failure were poor vascular condition (91.3%), old age (52.2%), skin lesions (39.1%) and pipeline plugging (26.1%).The main reasons for choosing the peripheral vein were lower risk of infection (87.0%), short-term treatment (82.6%), common transfusion (78.3%) and antibiotic treatment (47.8%).The main reasons for choosing central venous infusion were irritant drugs (82.6%), peripheral vascular puncture difficulty (69.6%), long-term infusion (65.2%) and hemodynamic monitor (56.5%). ConclusionsIt is difficult to establish a vascular access for critically ill patients.The ICU medical staffs are experienced to PIV, ACVC and PICC but not to Midline, TCVC and PORT.A comprehensive evaluation is essential to choose a suitable and reliable venous access device for critically ill patients.
ObjectiveTo compare early outcomes of the minimally invasive mitral valve surgery (MIMVS) through right anterolateral mini-thoracotomy (ALMT) with conventional mitral valve surgery (MVS), and evaluate feasibility and safety of MIMVS. MethodsFrom January 2011 to December 2013, 120 patients undergoing elective MVS in Nanjing First Hospital were prospectively enrolled in this study. There were 72 male and 48 female patients with their age of 22-71 (42.4±11.0) years. Using a random number table, all the patients were randomly divided into a portaccess MIMVS group (MIMVS group, n=60) and a conventional MVS group (conventional group, n=60). MIMVS group patients received port-access cardiopulmonary bypass (CPB) establishment via femoral artery, femoral vein and right internal jugular vein cannulation through right ALMT 5-6 cm in length. Special MIMVS operative instruments were used for mitral valve repair or replacement. Conventional group patients received mitral valve repair or replacement under conventional CPB through median sternotomy. Perioperative clinical data, morbidity and mortality were compared between the 2 groups. ResultsThere was no death in-hospital or shortly after discharge in this study. CPB time (98.0±26.0 minutes vs. 63.0±21.0 minutes) and aortic cross-clamping time (68.0±9.0 minutes vs.37.0±6.0 minutes) of MIMVS group were significantly longer than those of conventional group (P<0.05). Postoperative mechanical ventilation time (6.0±3.9 hours vs. 11.2±5.6 hours), length of ICU stay (18.5±3.0 hours vs. 28.6±9.5 hours) and postoperative hospital stay (8.0±2.0 days vs. 13.5±2.5 days) of MIMVS group were significantly shorter than those of conventional group (P<0.05). Chest drainage volume within postoperative 12 hours (110.0±30.0 ml vs. 385.0±95.0 ml) and the percentage of patients receiving blood transfusion (25.0% vs. 58.3%) of MIMVS group were significantly lower than those of conventional group (P<0.05). Patients were followed up for 1-24 months, and the follow-up rate was 94.2%. There was no statistical difference in postoperative morbidity or mortality between the 2 groups (P>0.05). ConclusionMIMVS through right ALMT is a safe and feasible procedure for surgical treatment of mitral valve diseases. MIMVS can achieve similar clinical outcomes as conventional MVS, but can significantly shorten postoperative ICU stay and hospital stay, reduce blood transfusion, and is a good alternative to conventional MVS.
ObjectiveTo systematically assess the efficacy and safety of percutaneous access and surgical cutdown in transfemoral transcatheter aortic valve implantation (TF-TAVI).MethodsWe searched databases including the Cochrane Library, PubMed, OVID, Embase, China National Knowledge Internet and Wanfang Database to collect randomized or non-randomized controlled trials comparing percutaneous access (PC group, the trial/exposure group) with surgical cutdown (SC group, the control group) in TF-TAVI between January 2002 and October 2017. The quality evaluation and data extraction were carried out by 2 reviewers independently. The Meta-analysis was performed using RevMan 5.3.5 software.ResultsA total of 11 literatures involving 4 893 aortic valve stenosis patients treated by TF-TAVI (2 877 patients in PC group and 2 016 patients in SC group) were included in this Meta-analysis. There was no significant difference between PC and SC group in terms of major vascular complications [odds ratio (OR)=0.86, 95% confidence interval (CI) (0.70, 1.06), P=0.17], minor vascular complications [OR=1.43, 95%CI (0.87, 2.37), P=0.16], major bleeding [OR=1.02, 95%CI (0.55, 1.90), P=0.94], minor bleeding [OR=0.90, 95%CI (0.51, 1.61), P=0.73] and all-cause mortality within 30 days [OR=1.03, 95%CI (0.76, 1.40), P=0.85]. As for the length of stay after TAVI, there was significant difference between the two groups [standard mean difference=–0.32, 95%CI (–0.52, –0.12), P=0.002].ConclusionPercutaneous access is as effective and safe as surgical cutdown in TF-TAVI, meanwhile leading to shorter length of stay after TAVI.
ObjectiveTo compare dialysis catheter function and complications according to catheter site in patients undergoing hemopurification.MethodsLiteratures were searched from PubMed, Medline, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang Data, and VIP Database according to the inclusion and exclusion criteria. Publication years of these literatures ranged from April 1998 to April 2018. Meta-analysis was performed with RevMan 5.3 software. The odds ratio (OR) and 95% confidence intervals (CI) were calculated for uncontinuous outcomes, and the weighted mean difference (WMD) and 95%CI were calculated for continuous outcomes. The incidence of catheter related infection, other complications and patients outcome were compared between different sites for dialysis vascular access.ResultsA total of 9 articles were included, including 2 randomized controlled trials and 7 observational clinical studies, and 5 220 adult patients undergoing renal replacement therapy. Meta-analysis showed that there was no significant difference in incidences of catheter colonization or catheter-related bloodstream infection, as well as arterial puncture, local thrombosis, catheter dysfunction and spontaneous catheter withdrawal, between femoral and non-femoral (jugular or subclavian) catheterization (P≥0.05). Whereas the incidence of bleeding and local hematoma was lower in femoral catheterization [OR=0.44, 95%CI (0.23, 0.82), P=0.009], and the duration of catheters was shorter in femoral catheterization [WMD=–1.40 d, 95%CI (–2.17, –0.62) d, P=0.000 4]. The blood flow rate, filters clotting incidence and patients intensive case unit mortality were similar in different catheterization.ConclusionsIn patients undergoing renal replacement therapy, the bleeding and local hematoma incidence is lower in femoral catheterization but the duration of catheters is shorter. Nevertheless the patients have similar clinical outcome. This result may provide reference for clinical decision-making.
ObjectiveTo evaluate the safety and efficacy of second central venous catheterization in tunnel cuffed dialysis catheter (TCC) dysfunction with fibrin sheath.MethodA total of 14 maintenance hemodialysis patients who required second central venous catheterization were enrolled in West China Hospital of Sichuan University from June 2016 to June 2017 and the clinical information and procedure-related complications were recorded.ResultsAll of the 14 patients were successfully performed with second central venous catheterization, of whom 4 cases had superior vena cava cannulation, 7 cases had right brachiocephalic vein cannulation, 2 cases had internal jugular vein cannulation, and 1 case had external jugular vein cannulation. No procedure-related major complication occurred. During the follow-up, catheter malfunction occurred in 2 cases, which improved by urokinase seal and catheter change, respectively. The rest patients’ catheter function remained normal.ConclusionsWith increasing difficult to construction and maintenance of vascular access, preservation of central vein resource is of high importance. For patients with TCC dysfunction with fibrin sheath, second central venous catheterization based on percutaneous brachiocephalic vein or superior vena cava cannulation is a safe and effective method to establish the lifeline for hemodialysis patients.
