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 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 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.
Objective To observe the effectiveness of IMPACT management mode on self-care and management abilities of breast cancer patients undergoing chemotherapy with implantable venous access port (VAP). Methods Breast cancer patients who underwent chemotherapy with VAP at Shangjin Hospital, West China Hospital, Sichuan University between March 2020 and June 2021 were prospectively included. IMPACT mode was used for self-management training guidance. The patient self-care abilities before training and at 1 month, 2 months, and 3 months of training were compared, and the patient self-management abilities at 1 month and 3 months of training were compared. Results A total of 74 patients with breast cancer undergoing chemotherapy with VAP were included. The total score of self-care ability of patients before training and at 1 month, 2 months, and 3 months of training was 112.11±14.63, 123.20±15.73, 127.95±13.89, and 131.92±13.60, respectively, and all the between-time-point differences were statistically significant (P<0.05). In terms of self-concept score, all the between-time-point differences were statistically significant (P<0.05) with increasing score over time, except the difference between the score at 3 months of training and that at 2 months of training (P>0.05). In terms of self-responsibility and self-care skill scores, all the between-time-point differences were statistically significant (P<0.05) with increasing scores over time, except the difference between the score at 2 months of training and that at 1 month of training (P>0.05). In terms of health knowledge level, the scores at 1 month, 2 months, and 3 months of training were higher than that before training (P<0.05), and the score at 3 months of training was higher than that at 1 month of training (P<0.05). The self-management ability scores in all dimensions at 3 months of training were higher than those at 1 month of training, and the differences were statistically significant (P<0.05). Conclusion The IMPACT management mode can effectively improve the self-care and management abilities of breast cancer patients undergoing chemotherapy with VAP, thereby ensuring the normal use of VAP, reducing the occurrence of complications, and reducing the burden on families and society.
Objective To explore the vascular access infection (VAI) incidence of hemodialysis patients during the the maximum spread of the COVID-19 epidemic (epidemic period) compared with the corresponding period with no local cases of COVID-19 (control period). Methods A single-center, retrospective study was carried out. Adult patients who underwent hemodialysis at the Department of Blood Purification Center, the Affiliated Hospital of Xuzhou Medical University during the epidemic period between December 7, 2022 and February 23, 2023 and the control period between December 7, 2020 and February 23, 2021 were selected. The incidence of local access site infection (LASI) and access related bloodstream infection (ARBSI) in included patients were observed and compared. ResultsA total of 1 401 patients were included. Among them, there were 737 cases during the epidemic period and 664 cases during the control period. There was no statistically significant difference in the age, gender, and duration of catheterization among patients of different periods and pathway types (P>0.05). There was no statistically significant difference in the occurrence of LASI between the epidemic period and the control period (χ2=1.800, P=1.180). There was a statistically significant difference in the occurrence of ARBSI between the epidemic period and the control period [χ2=4.610, relative risk (RR)=2.575, 95% confidence interval (CI) (1.053, 6.298), P=0.032]. There was no statistically significant difference in the incidence of LASI and ARBSI at different stages in patients with arteriovenous fistula and unnel-cuffed catheters (TCC) (P＞0.05). There were statistically significant differences in the incidence of LASI [χ2=4.898, RR=3.832, 95%CI (1.058, 13.885), P=0.027] and ARBSI [χ2=7.150, RR=4.684, 95%CI (1.333, 16.460), P=0.005] among non cuffed catheters (NCC) patients at different stages. TCC patients might experience LASI (P<0.05) during the epidemic period and ARBSI (P<0.05) during the control period compared with the arteriovenous fistula patients; both central venous catheterization and NCC patients might experience LASI and ARBSI during the control period (P<0.05). Conclusion Targeting COVID-19 prevention may be associated with the reduction of vascular access infection in hemodialysis patients, in particular in NCC patients.
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.
【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 feasibility and effectiveness of robot-assisted posterior minimally invasive access in treatment of thoracolumbar tuberculosis via transforaminal expansion approach. Methods A clinical data of 40 patients with thoracolumbar tuberculosis admitted between January 2017 and May 2022 and met the selection criteria was retrospectively analyzed. Among them, 15 cases were treated with robot-assisted and minimally invasive access via transforaminal expansion approach for lesion removal, bone graft, and internal fixation (robotic group), and 25 cases were treated with traditional transforaminal posterior approach for lesion removal and intervertebral bone grafting (traditional group). There was no significant difference in the baseline data between the two groups (P>0.05) in terms of gender, age, lesion segment, and preoperative American Spinal Injury Association (ASIA) grading, Cobb angle, visual analogue scale (VAS) score, erythrocyte sedimentation rate (ESR), and C reactive protein (CRP). The outcome indicators were recorded and compared between the two groups, including operation time, intraoperative bleeding volume, hospital stay, postoperative bedtime, complications, ESR and CRP before operation and at 1 week after operation, the level of serum albumin at 3 days after operation, VAS score and ASIA grading of neurological function before operation and at 6 months after operation, the implant fusion, fusion time, Cobb angle of the lesion, and the loss of Cobb angle observed by X-ray films and CT. The differences of ESR, CRP, and VAS score (change values) between pre- and post-operation were calculated and compared. Results Compared with the traditional group, the operation time and intraoperative bleeding volume in the robotic group were significantly lower and the serum albumin level at 3 days after operation was significantly higher (P<0.05); the postoperative bedtime and the length of hospital stay were also shorter, but the difference was not significant (P>0.05). There were 2 cases of poor incision healing in the traditional group, but no complication occurred in the robotic group, and the difference in the incidence of complication between the two groups was not significant (P>0.05). There were significant differences in the change values of ESR and CRP between the two groups (P<0.05). All Patients were followed up, and the follow-up time was 12-18 months (mean, 13.0 months) in the traditional group and 12-16 months (mean, 13.0 months) in the robotic group. Imaging review showed that all bone grafts fused, and the difference in fusion time between the two groups was not significant (P>0.05). The difference in Cobb angle between the pre- and post-operation in the two groups was significant (P<0.05); and the Cobb angle loss was significant more in the traditional group than in the robotic group (P<0.05). The VAS scores of the two groups significantly decreased at 6 months after operation when compared with those before operation (P<0.05); the difference in the change values of VAS scores between the two groups was not significant (P>0.05). There was no occurrence or aggravation of spinal cord neurological impairment in the two groups after operation. There was a significant difference in ASIA grading between the two groups at 6 months after operation compared to that before operation (P<0.05), while there was no significant difference between the two groups (P>0.05). Conclusion Compared with traditional posterior open operation, the use of robot-assisted minimally invasive access via transforaminal approach for lesion removal and bone grafting internal fixation in the treatment of thoracolumbar tuberculosis can reduce the operation time and intraoperative bleeding, minimizes surgical trauma, and obtain definite effectiveness.
ObjectiveTo provide policy suggestions concerning the distribution of health resources between urban and rural areas and management and education of diabetes, this study depicted the current status of access to healthcare and analyzed its determinants among Chinese diabetic patients.MethodsMultivariate ordinal logistic regression and multivariate binary logistic regression were employed to analyze the effects of socioeconomic status and urban-rural disparities on health access.ResultsMultivariate results suggested that urban patients were more likely to conduct more blood glucose tests (P<0.000 1) and receive more self-care suggestions from physicians (P=0.02). After controlling all other covariates, patients graduated from secondary schools and those with vocational school degrees or above were 1.61 and 2.44 times more possible to take more blood glucose tests.Conclusions There exists significant urban-rural disparities of access to healthcare among Chinese diabetic patients. Education may be a key factor of access to healthcare among Chinese diabetic patients. It’s highly recommended to implement education programs on diabetes management in rural areas, where the education status and demographic factors should be considered. The distribution of health resource in rural areas requires more policy and governmental support.
ObjectiveTo explore the effectiveness of modified internal fixation and fusion in treatment of type Ⅱ painful accessory navicular (PAN) in adults.MethodsBetween January 2016 and December 2017, 29 patients (37 feet) with type Ⅱ PAN were treated with modified internal fixation and fusion. There were 12 males and 17 females with an average age of 41.4 years (range, 18-50 years). The injury caused by sprain in 24 cases and no obvious inducement occurred in 5 cases. All patients received conservative treatment for more than 6 months with no significant improvement. The effectiveness was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score before operation and at last follow-up. The inclination angle of calcaneus, the first metatarsal angle of talus, the inclusion angle of talonavicular joint, and the second metatarsal angle of talus were measured on X-ray films.ResultsSuperficial infection of incision occurred in 1 case after operation, and the incision healed after enhanced dressing change. The incisons of the other patients healed by first intention. There was no deep infection or osteomyelitis. All patients were followed up 12-33 months (mean, 25.1 months). X-ray films showed that the articular surfaces healed at 2-5 months after operation, with an average of 3.4 months. No loosening or rupture of internal fixator was found during the follow-up. At last follow-up, the pain, function, alignment scores, and total score of AOFAS were significantly improved when compared with those before operation (P<0.05). The inclusion angle of talonavicular joint, the first metatarsal angle of talus, and the second metatarsal angle of talus were also significantly improved when compared with those before operation (P<0.05). But there was no significant difference in the inclination angle of calcaneus between pre- and post-operation (t=1.097, P=0.276).ConclusionModified internal fixation and fusion in treatment of type Ⅱ PAN can effectively relieve the symptoms and obtain good recovery of feet function with less complications.
