Background Context

Degenerative cervical myelopathy (DCM) is a progressive degenerative spine disease and the most common cause of spinal cord impairment in adults worldwide. Few studies have reported on regional variations in demographics, clinical presentation, disease causation, and surgical effectiveness.

Purpose

The objective of this study was to evaluate differences in demographics, causative pathology, management strategies, surgical outcomes, length of hospital stay, and complications across four geographic regions.

Study Design/Setting

This is a multicenter international prospective cohort study.

Patient Sample

This study includes a total of 757 symptomatic patients with DCM undergoing surgical decompression of the cervical spine.

Outcome Measures

The outcome measures are the Neck Disability Index (NDI), the Short Form 36 version 2 (SF-36v2), the modified Japanese Orthopaedic Association (mJOA) scale, and the Nurick grade.

Materials and Methods

The baseline characteristics, disease causation, surgical approaches, and outcomes at 12 and 24 months were compared among four regions: Europe, Asia Pacific, Latin America, and North America.

Results

Patients from Europe and North America were, on average, older than those from Latin America and Asia Pacific (p=.0055). Patients from Latin America had a significantly longer duration of symptoms than those from the other three regions (p<.0001). The most frequent causes of myelopathy were spondylosis and disc herniation. Ossification of the posterior longitudinal ligament was most prevalent in Asia Pacific (35.33%) and in Europe (31.75%), and hypertrophy of the ligamentum flavum was most prevalent in Latin America (61.25%). Surgical approaches varied by region; the majority of cases in Europe (71.43%), Asia Pacific (60.67%), and North America (59.10%) were managed anteriorly, whereas the posterior approach was more common in Latin America (66.25%). At the 24-month follow-up, patients from North America and Asia Pacific exhibited greater improvements in mJOA and Nurick scores than those from Europe and Latin America. Patients from Asia Pacific and Latin America demonstrated the most improvement on the NDI and SF-36v2 PCS. The longest duration of hospital stay was in Asia Pacific (14.16 days), and the highest rate of complications (34.9%) was reported in Europe.

Conclusions

Regional differences in demographics, causation, and surgical approaches are significant for patients with DCM. Despite these variations, surgical decompression for DCM appears effective in all regions. Observed differences in the extent of postoperative improvements among the regions should encourage the standardization of care across centers and the development of international guidelines for the management of DCM.  相似文献

Background

Odontoid process fractures, of which type II constitute the majority, are an increasingly important cause of morbidity and mortality in the elderly population. The incidence of geriatric type II fractures is steadily increasing in line with the aging population. However, the decision between surgical and non-surgical intervention for type II fractures in the elderly remains controversial.

Purpose

The present study aims to synthesize the current published literature comparing outcomes following surgical and non-surgical interventions for type II odontoid fractures in the elderly population (≥65 years old).

Study design/setting

Systematic review and meta-analysis were performed.

Methods

A systematic search of MEDLINE, MEDLINE In-Progress & Other Non-Indexed Citations, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) was performed to identify available evidence in English language. Studies with extractable data for all type II odontoid fractures in participants aged 65 years or older and which compared surgical and non-surgical intervention were included. Methodological quality was assessed using the Downs & Black checklist. Primary outcomes were mortality at short-term follow-up (≤3 months), mortality at long-term follow-up (predetermined study endpoint or mean follow-up length), and radiological union rate. Funding was provided by The University of Edinburgh for travel expenses to present this paper at the Society of British Neurological Sciences 2016 Conference ($170).

Results

Twelve studies (n=1,098), all non-randomized, met eligibility criteria. Methodological quality was particularly poor in the confounding, bias, and power domains of assessment. Substantial methodological and statistical heterogeneity allowed only a narrative synthesis of the primary outcomes. Overall, data on mortality at short-term follow-up appeared to favor neither surgical nor non-surgical intervention. A small favorable outcome in surgically managed patients over non-surgically managed patients in terms of mortality at long-term follow-up was not proven conclusive because of considerable heterogeneity in study methodologies. Inadequate reporting of the time point of union assessment introduced the potential for significant intra- and interstudy heterogeneity and precluded assessment of union rates.

Conclusions

Evidence on this controversial topic is sparse, markedly heterogeneous, and of poor quality. Well-designed prospective trials adhering to guidance published by the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) initiative are required to inform clinical practice on this contentious but growing issue. Future randomized controlled trials should include an assessment of frailty and medical comorbidities with suitable patients subsequently randomized to surgical or non-surgical treatment.  相似文献

Although laparoscopic sleeve gastrectomy is an established operation for severe obesity, there is controversy regarding the extent to which the antrum is excised. The objective of this systematic review was to investigate the effect on perioperative complications and medium-term outcomes of antral resecting versus antral preserving sleeve gastrectomy. MEDLINE, EMBASE, and Cochrane databases were searched from 1946 to April 2017. Eligible studies compared antral resection (staple line commencing 2–3 cm from pylorus) with antral preservation (>5 cm from pylorus) in patients undergoing primary sleeve gastrectomy for obesity. Meta-analyses were performed with a random-effects model, and risk of bias within and across studies was assessed using validated scoring systems. Eight studies (619 participants) were included: 6 randomized controlled trials and 2 cohort studies. Overall follow-up was 94% for the specified outcomes of each study. Mean percentage excess weight loss was 62% at 12 months (7 studies; 574 patients) and 67% at 24 months (4 studies; 412 patients). Antral resection was associated with significant improvement in percentage excess weight loss at 24-month follow-up (mean 70% versus 61%; standardized mean difference .95; confidence interval .35–1.58, P<.005), an effect that remained significant when cohort studies were excluded. There was no difference in incidence of perioperative bleeding, leak, or de novo gastroesophageal reflux disease. According to the available evidence, antral resection is associated with better medium-term weight loss compared with antral preservation, without increased risk of surgical complications. Further randomized clinical trials are indicated to confirm this finding.  相似文献

Background

The National Bariatric Surgery Registry (NBSR) is the largest bespoke database in the field in the United Kingdom.

Objectives

Our aim was to analyze the NBSR to determine whether the effects of obesity surgery on associated co-morbidities observed in small randomized controlled clinical trials could be replicated in a "real life" setting within U.K. healthcare.

Setting

United Kingdom.

Methods

All NBSR entries for operations between 2000 and 2015 with associated demographic and co-morbidity data were analyzed retrospectively.

Results

A total of 50,782 entries were analyzed. The patients were predominantly female (78%) and white European with a mean age of 45 ± 11 years and a mean body mass index of 48 ± 8 kg/m2. Over 5 years of follow-up, statistically significant reductions in the prevalence of type 2 diabetes, hypertension, dyslipidemia, sleep apnea, asthma, functional impairment, arthritis, and gastroesophageal reflux disease were observed. The "remission" of these co-morbidities was evident 1 year postoperatively and reached a plateau 2 to 5 years after surgery. Obesity surgery was particularly effective on functional impairment and diabetes, almost doubling the proportion of patients able to climb 3 flights of stairs and halving the proportion of patients with diabetes related hyperglycemia compared with preoperatively. Surgery was safe with a morbidity of 3.1% and in-hospital mortality of .07% and a reduced median inpatient stay of 2 days, despite an increasingly sick patient population.

Conclusions

Obesity surgery in the U.K. results not only in weight loss, but also in substantial improvements in obesity-related co-morbidities. Appropriate support and funding will help improve the quality of the NBSR data set even further, thus enabling its use to inform healthcare policy.  相似文献

Background

The number of octogenarians undergoing revision total knee arthroplasty (TKA) is increasing. However, there has been a lack of studies investigating the perioperative course and safety of revision TKA performed in this potentially vulnerable population in a large patient population. The purpose of this study is to compare complications following revision TKA between octogenarians and 2 younger patient populations (<70 and 70-79 year olds).

Methods

Patients who underwent revision TKA were identified in the 2005-2015 National Surgical Quality Improvement Program database and stratified into 3 age groups: <70, 70-79, and ≥80 years. Baseline preoperative and intraoperative characteristics were compared between the 3 groups. Propensity score matched comparisons were then performed for 30-day perioperative complications, length of hospital stay, and readmissions.

Results

This study included 6523 (<70 years), 2509 (70-79 years), and 957 octogenarian patients who underwent revision TKA. After propensity matching, statistical analysis revealed only higher rates of blood transfusion and slightly longer length of stay in octogenarians compared to <70 year olds. Similarly, octogenarians had only higher rates of blood transfusion and slightly longer length of stay compared to 70-79 year olds. Notably, there were no differences in mortality or readmission between octogenarians compared to younger populations.

Conclusion

These data suggest that revision TKA can safely be considered for octogenarians with the observation of higher rates of blood transfusion and slightly longer length of stay compared to younger populations. Octogenarian patients need not be discouraged from revision TKA solely based on their advanced age.  相似文献

The tracheocutaneous fistula after tracheostomy is a complex clinical problem. An ideal fistula closure is still difficult at present though a variety of fistula-closing methods have been reported in the literature. We used a turnover skin flap to cover the fistula. All the procedures were completed at bedside under local anesthesia. The fistula was successfully closed and well healed without complications within 7-9 days. It has been proven that this operation is simple, effective, and safe.  相似文献

Purpose

To compare the efficacy of RIRS and PNL in lower pole stones ≥2 cm. Materials and and Methods: A total of 109 patients who underwent PNL or RIRS for solitary lower pole stone between April 2009 and December 2012, were retrospectively analyzed. Lower pole stone was diagnosed with CT scan. Stone size was assessed as the longest axis of the stone. All patients were informed about the advantages, disadvantages and probable complications of both PNL and RIRS before the selection of the procedure. Patients decided the surgery type by themselves without being under any influences and written informed consent was obtained from all patients prior to the surgery. Patients were divided into two groups according to the patients’ preference of surgery type. Group 1 consisted of 77 patients who underwent PNL and Group 2 consisted of 32 patients treated with RIRS. Stone free statuses, postoperative complications, operative time and hospitalization time were compared in both groups.

Results

There was no statistical significance between the two groups in mean age, stone size, stone laterality, mean follow-up periods and mean operative times. In PNL group, stone-free rate was 96.1% at first session and 100% after the additional procedure. In Group 2, stone-free rate was 90.6% at the first procedure and 100% after the additional procedure. The final stone-free rates and operative times were similar in both groups.

Conclusions

RIRS should be an effective treatment alternative to PNL in lower pole stones larger than 2 cm, especially in selected patients.  相似文献
