BACKGROUND CONTEXT

Lumbar spinal stenosis (LSS) can impair blood flow to the spinal nerves giving rise to neurogenic claudication and limited walking ability. Reducing lumbar lordosis can increases the volume of the spinal canal and reduce neuroischemia. We developed a prototype LSS belt aimed at reducing lumbar lordosis while walking.

PURPOSE

The aim of this study was to assess the short-term effectiveness of a prototype LSS belt compared to a lumbar support in improving walking ability in patients with degenerative LSS.

STUDY DESIGN

This was a two-arm, double-blinded (participant and assessor) randomized controlled trial.

PATIENT SAMPLE

We recruited 104 participants aged 50 years or older with neurogenic claudication, imaging confirmed degenerative LSS, and limited walking ability.

OUTCOME MEASURES

The primary measure was walking distance measured by the self-paced walking test (SPWT) and the primary outcome was the difference in proportions among participants in both groups who achieved at least a 30% improvement in walking distance from baseline using relative risk with 95% confidence intervals.

METHODS

Within 1 week of a baseline SPWT, participants randomized to the prototype LSS belt group (n=52) and those randomized to the lumbar support group (n=52) performed a SPWT that was conducted by a blinded assessor. The Arthritis Society funded this study ($365,000 CAN) with salary support for principal investigator funded by the Canadian Chiropractic Research Foundation ($500,000 CAN for 5 years).

RESULTS

Both groups showed significant improvement in walking distance, but there was no significant difference between groups. The mean group difference in walking distance was ?74 m (95% CI: ?282.8 to 134.8, p=.49). In total, 62% of participants wearing the prototype LSS belt and 82% of participants wearing the lumbar support achieved at least 30% improvement in walking distance (relative risk, 0.7; 95% CI: 0.5–1.3, p=.43).

CONCLUSIONS

A prototype LSS belt demonstrated significant improvement in walking ability in degenerative LSS but was no better than a lumbar support.  相似文献

BACKGROUND CONTEXT

Patients with pyogenic vertebral osteomyelitis (PVO) are expected to have an increased risk of bone loss. Therefore, early bisphosphonate therapy would be clinically effective for PVO patients with osteoporosis.

PURPOSE

This study aimed to investigate the effect of bisphosphonate on clinical outcomes of PVO patients with osteoporosis.

STUDY DESIGN/SETTING

A retrospective comparative study.

PATIENT SAMPLE

PVO patients with osteoporosis.

OUTCOME MEASURES

Four events of interest for Cox proportional hazard model included surgical treatment, recurrence of infection, subsequent fracture of adjacent vertebral bodies, and death.

METHODS

PVO patients were divided into three groups: group A (initiation of bisphosphonate within 6 weeks after PVO diagnosis), group B (initiation of bisphosphonate between 6 weeks and 3 months after PVO diagnosis), and group C (no treatment for osteoporosis). Cox proportional hazard model was used for the four events of interest.

RESULTS

A total of 360 PVO patients with osteoporosis were investigated for the four events of interest. Group A had significantly lower hazard ratios for undergoing later (>6 weeks after diagnosis) surgery than group C (p?=?.014) despite similar occurrences of overall surgery. A significant difference was also observed in the occurrence of subsequent fractures at adjacent vertebral bodies (p?=?.001 for model 1 and p?=?.002 for model 2). Groups A and B had significantly lower hazard ratios for subsequent fracture than group C. No significant differences were observed in the hazard ratios of recurrence and death among the three groups.

CONCLUSIONS

Early bisphosphonate treatment in PVO patients with osteoporosis was associated with a significantly lower occurrence of subsequent vertebral fracture at adjacent vertebral bodies and lower occurrence of subsequent surgery.  相似文献

BACKGROUND CONTEXT

Spinal epidural lipomatosis (SEL) is a condition in which excess lumbar epidural fat (EF) deposition often leads to compression of the cauda equina or nerve root. Although SEL is often observed in obese adults, no systematic research investigating the potential association between SEL and metabolic syndrome has been conducted.

PURPOSE

To elucidate potential association between SEL and metabolic syndrome.

STUDY DESIGN

An observational study used data of a medical checkup.

PATIENT SAMPLE

We retrospectively reviewed data from consecutive subjects undergoing medical checkups. A total of 324 subjects (174 men and 150 women) were enrolled in this study.

OUTCOME MEASURES

The correlation of EF accumulation with demographic data and metabolic-related factors was evaluated.

METHODS

The degree of EF accumulation was evaluated based on the axial views of lumbar magnetic resonance imaging. Visceral and subcutaneous fat areas were measured at the navel level using abdominal computed tomography. Metabolic syndrome was diagnosed according to the criteria of the Japanese Society of Internal Medicine. The correlation of SEL with metabolic syndrome and metabolic-related conditions was statistically evaluated.

RESULTS

The degree of EF accumulation demonstrated a significant correlation to body mass index, abdominal circumference, and visceral fat area. However, age, body fat percentage, and subcutaneous fat area showed no correlation with the degree of EF accumulation. Logistic regression analysis revealed that metabolic syndrome (odds ratio [OR]=3.8, 95% confidence interval [CI]=1.5–9.6) was significantly associated with SEL. Among the diagnostic criteria for metabolic syndrome, visceral fat area ≥100 cm2 (OR=4.8, 95% CI=1.5–15.3) and hypertension (OR=3.5, 95% CI=1.1–11.8) were observed to be independently associated with SEL.

CONCLUSION

This is the first study to demonstrate that metabolic syndrome is associated with SEL in a relatively large, unbiased population. Our data suggest that metabolic-related conditions are potentially related to EF deposition and that SEL could be a previously unrecognized manifestation of metabolic syndrome.  相似文献

BACKGROUND CONTEXT

Pedicle screw loosening is common after spinal fusion and can be associated with pseudoarthrosis and pain. With suspicion of screw loosening on standard radiographs, CT is currently considered the advanced imaging modality of choice. MRI with new metal artifact reduction techniques holds potential to be sensitive in detection of screw loosening. The sensitivity and specificity of either of the imaging modalities are yet clear.

PURPOSE

To evaluate the sensitivity and specificity of three different image modalities (standard radiographs, CT, and MRI) for detection of pedicle screw loosening.

STUDY DESIGN/SETTING

Cross-sectional diagnostic study.

PATIENT SAMPLE

Forty-one patients (159 pedicle screws) undergoing revision surgeries after lumbar spinal fusion between August 2014 and April 2017 with preoperative radiographs, CT, and MRI with spinal metal artifact reduction (STIR WARP and TSE high bandwidth sequences).

OUTCOME MEASURES

Sensitivity and specificity in detection of screw loosening for each imaging modality.

METHODS

Screw torque force was measured intraoperatively and compared with preoperative screw loosening signs such as peri-screw edema in MRI and peri-screw osteolysis in CT and radiographs. A torque force of less than 60 Ncm was used to define a screw as loosened.

RESULTS

Sensitivity and specificity in detection of screw loosening was 43.9% and 92.1% for MRI, 64.8% and 96.7% for CT, and 54.2% and 83.5% for standard radiographs, respectively.

CONCLUSIONS

Despite improvement of MRI with metal artifact reduction MRI technique, CT remains the modality of choice. Even so, CT fails to detect all loosened pedicle screws.  相似文献

BACKGROUND

The pattern of linear graph schematized by visual analogue scale (VAS) score displaying pain worsening between 2 days and 2 weeks after selective nerve root block (SNRB) is called rebound pain.

PURPOSE

The purpose of this study was to determine if sodium hyaluronate and carboxymethyl cellulose solution (HA-CMC sol) injection could reduce the occurrence of rebound pain at 3 days to 2 weeks after SNRB in patients with radiculopathy compared with injection with corticosteroids and local anesthetics alone.

STUDY DESIGN/SETTING

Double blinded randomized controlled clinical trial.

PATIENT SAMPLE

A total of 44 patients (23 of 24 patients in the Guardix group and 21 of 24 patients in the control group) who finished the follow-up session were subjects of this study.

OUTCOME MEASUREMENT

Patients were asked to write down their average VAS pain scores daily for 12 weeks. Functional outcomes were assessed by Oswestry Disability Index, Roland Morris Disability Questionnaire , and Short Form-36.

METHOD

A cocktail of corticosteroids, 1% lidocaine, 0.5% Bupivacaine, and 1 mL of normal saline was used for the control group whereas a cocktail of corticosteroids, 1% lidocaine, 0.5% Bupivacaine, and 1 mL of HA-CMC solution was used for the G group. Study participants were randomized into one of two treatment regimens. They were followed up for 3 months.

RESULTS

VAS score at 2 weeks after the procedure was 4.19±1.32 in the control group, which was significantly (p<.05) higher than that (2.43±1.24) in the G group. VAS score at 6 weeks after the procedure was 4.00±1.23 in the control group and 3.22±1.45 in the G group, showing no significant (p=.077) difference between the two groups. There were no significant differences in functional outcomes at 6 or 12 weeks after the procedure.

CONCLUSIONS

Compared with conventional cocktail used for SNRB, addition of HA-CMC sol showed effective control of rebound pain at 3 days to 2 weeks after the procedure.  相似文献

BACKGROUND CONTEXT

Data on the long-term outcome after fusion for isthmic spondylolisthesis are scarce.

PURPOSE

To study patient-reported outcomes and adjacent segment degeneration (ASD) after fusion for isthmic spondylolisthesis and to compare patient-reported outcomes with a control group.

STUDY DESIGN/SETTING

A prospective study including a cross-sectional control group.

PATIENT SAMPLE

Patients with isthmic spondylolisthesis underwent posterior lumbar interbody fusion (PLIF) (n=86) or posterolateral fusion (PLF) (n=77). Patient-reported outcome data were available for 73 patients in the PLIF group and 71 in the PLF group at a mean of 11 (range 5–16) years after baseline. Seventy-seven patients in the PLIF group and 54 in the PLF group had radiographs at a mean of 14 (range 9–19) years after baseline. One hundred thirty-six randomly selected persons from the population served as controls for the patient-reported outcomes.

OUTCOME MEASURES

Patient-reported outcomes include the following: global outcome, Oswestry Disability Index, Disability Rating Index, and Short Form 36. The ASD was determined from radiographs using the University of California Los Angeles (UCLA) grading scale.

METHODS

: The chi-square test or analysis of covariance (ANCOVA) was used for group comparisons. The ANCOVA was adjusted for follow-up time, smoking, Meyerding slippage grade, teetotaler (yes/no) and, if available, the baseline level of the dependent variable.

RESULTS

There were no significant patient-reported outcome differences between the PLIF group and the PLF group. The prevalence of ASD was 42% (32/77) in the PLIF group and 26% (14/54) in the PLF group (p=.98). The patient-reported outcome data indicated lower physical function and more pain in individuals with surgically treated isthmic spondylolisthesis compared to the controls.

CONCLUSIONS

PLIF and PLF groups had similar long-term patient-reported and radiological outcomes. Individuals with isthmic spondylolisthesis have lower physical function and more pain several years after surgery when compared to the general population.  相似文献

Background Context

Posterior lumbar fusion (PLF) is a commonly performed procedure. The evolution of bundled payment plans is beginning to require physicians to more closely consider patient outcomes up to 90 days after an operation. Current quality metrics and other databases often consider only 30 postoperative days. The relatively new Healthcare Cost and Utilization Project Nationwide Readmissions Database (HCUP-NRD) tracks patient-linked hospital admissions data for up to one calendar year.

Purpose

To identify readmission rates within 90 days of discharge following PLF and to put this in context of 30 day readmission and baseline readmission rates.

Study Design

Retrospective study of patients in the HCUP-NRD.

Patient Sample

Any patient undergoing PLF performed in the first 9 months of 2013 were identified in the HCUP-NRD.

Outcome Measures

Readmission patterns up to a full calendar year after discharge.

Methods

PLFs performed in the first 9 months of 2013 were identified in the HCUP-NRD. Patient demographics and readmissions were tracked for 90 days after discharge. To estimate the average admission rate in an untreated population, the average daily admission rate in the last quarter of the year was calculated for a subset of PLF patients who had their operation in the first quarter of the year. This study was deemed exempt by the institution's Human Investigation Committee.

Results

Of 26,727 PLFs, 1,580 patients (5.91%) were readmitted within 30 days of discharge and 2,603 patients (9.74%) were readmitted within 90 days of discharge. Of all readmissions within 90 days, 54.56% occurred in the first 30 days. However, if only counting readmissions above the baseline admission rate of a matched population from the 4th quarter of the year (0.08% of population/day), 89.78% of 90 day readmissions occurred within the first 30 days.

Conclusions

The current study delineates readmission rates after PLF and puts this in the context of 30-day readmission rates and baseline readmission rates for those undergoing PLF. These results are important for patient counseling, planning, and preparing for potential bundled payments in spine surgery.  相似文献

BACKGROUND CONTEXT

Although 40% of adolescent idiopathic scoliosis (AIS) patients present with chronic back pain, the pathophysiology and underlying pain mechanisms remain poorly understood. We hypothesized that development of chronic pain syndrome in AIS is associated with alterations in pain modulatory mechanisms.

PURPOSE

To identify the presence of sensitization in nociceptive pathways and to assess the efficacy of the diffuse noxious inhibitory control in patients with AIS presenting with chronic back pain.

STUDY DESIGN

Cross-sectional study.

PATIENT SAMPLE

Ninety-four patients diagnosed with AIS and chronic back pain.

OUTCOME MEASURES

Quantitative sensory testing (QST) assessed pain modulation and self-reported questionnaires were used to assess pain burden and health-related quality of life.

METHODS

Patients underwent a detailed pain assessment using a standard and validated quantitative sensory testing (QST) protocol. The measurements included mechanical detection thresholds (MDT), pain pressure threshold (PPT), heat pain threshold (HPT), heat tolerance threshold (HTT), and a conditioned pain modulation (CPM) paradigm. Altogether, these tests measured changes in regulation of the neurophysiology underlying the nociceptive processes based on the patient's pain perception. Funding was provided by The Louise and Alan Edwards Foundation and The Shriners Hospitals for Children.

RESULTS

Efficient pain inhibitory response was observed in 51.1% of patients, while 21.3% and 27.7% had sub-optimal and inefficient CPM, respectively. Temporal summation of pain was observed in 11.7% of patients. Significant correlations were observed between deformity severity and pain pressure thresholds (p=.023) and CPM (p=.017), neuropathic pain scores and pain pressure thresholds (p=.015) and temporal summation of pain (p=.047), and heat temperature threshold and pain intensity (p=.048).

CONCLUSIONS

Chronic back pain has an impact in the quality of life of adolescents with idiopathic scoliosis. We demonstrated a high prevalence of impaired pain modulation in this group. The association between deformity severity and somatosensory dysfunction may suggest that spinal deformity can be a trigger for abnormal neuroplastic changes in this population contributing to chronic pain syndrome.  相似文献

Background

Bariatric surgery has proven to be the most durable treatment for obesity, and it also provides improvement of obesity's associated co-morbidities. Although several mechanisms for its metabolic effects have been studied, the implications of the surgically constructed anatomy on its functioning physiology have not been elucidated. This leaves some uncertainty regarding the recommended limb lengths in Roux-en-Y gastric bypass. The alimentary limb length and function has been studied extensively, but few have studied the influences of the biliopancreatic limb length.

Objective

To present a systematic review of the literature comparing variations in length of BP limb and results in order to determine BP limb length influence.

Setting

Academic Hospital, United States.

Methods

We present a systematic review of all the articles comparing variations of the biliopancreatic limb length and their results.

Results

Thirteen articles were identified and analyzed. Most of the articles are prospective studies. Weight loss was superior in longer limbs.

Conclusion

Based on our review of the subject, we can conclude that the release of enterohormones in response to a food load in the distal small bowel seems to play an important role in the remission of co-morbidities. Hence, the length of the biliopancreatic limb might affect this process.  相似文献

BACKGROUND CONTEXT

Informed consent is mandatory before surgery and fundamental in the physician-patient interaction. However, communication is sometimes suboptimal.

PURPOSE

The objective was to develop a question prompt list (QPL) for patients undergoing spine surgery (spinal neurosurgery-QPL, “SN-QPL”) to encourage them to acquire information during the informed consent consultation (ICC) and assess patients’ information needs.

STUDY DESIGN/SETTING

We conducted a prospective uncontrolled single center study in order to develop a QPL for patients undergoing spine surgery.

PATIENT SAMPLE

Patients inclusion criteria were as follows: (1) planned spinal surgery, (2) age 18 to 80 years, (3) legal capacity, (4) ability to understand and respond to questionnaires, and (5) informed consent.

OUTCOME MEASURES

We applied the following self-report measures: the developed preliminary QPL with regard to surgery topics and assessment of patients’ information needs.

METHODS

First, we performed a literature review, patient interviews, and two expert rounds. Subsequently, we validated a preliminary SN-QPL including 37 items before and after ICC with regard to importance of items and fulfillment of information needs in 118 patients. A principal component analysis followed by varimax rotation revealed the final SN-QPL.

RESULTS

For the final version of the SN-QPL, 27 items with following four reliable subscales were derived with satisfactory internal consistency: (1) scale SN-QPL-C, “complications and possible postoperative deficits” (n??=??8 items, Cronbach α?=?0.88); (2) scale SN-QPL-P, “prognosis and follow-up” (n?=?8 items, Cronbach α?=?0.86); (3) scale SN-QPL-I, “preoperative inpatient stay and organizational issues” (n?=?5 items, Cronbach α?=?0.75); and (4) scale SN-QPL-S: “safety of the surgical procedure” (with n?=?6 items, Cronbach α?=?0.84). The most unmet information needs were found in SN-QPL-P. The item with the greatest unmet information needs was “How much professional experience does my surgeon have?”

CONCLUSIONS

Our SN-QPL was well-accepted and perceived as helpful by patients awaiting spinal surgeries. It seems to address meaningful items and questions. It could therefore be useful in optimizing pre- and postoperative satisfaction. Further, our study identified many unaddressed questions warranting communication interventions.  相似文献

BACKGOUND CONTEXT

Abnormal proximal femoral angle (PFA) was recently found to be associated with deteriorating sagittal balance and quality of life (QoL) in high-grade spondylolisthesis (HGS). However, the influence of PFA on the QoL of patients undergoing surgery remains unknown.

PURPOSE

This study compares the pre- and postoperative measurements of sagittal balance including PFA in patients with lumbosacral HGS after surgery. It also determines if PFA is a radiographic parameter that is associated with QoL in patients undergoing surgery.

STUDY DESIGN

Retrospective cohort study.

PATIENT SAMPLE

Thirty-three patients (mean age 15.6 ± 3.0 years) operated for L5-S1 HGS between July 2002 and April 2015. Thirteen had in situ fusion and 20 had reduction to a low-grade slip.

OUTCOME MEASURES

The outcome measures included PFA and QoL scores measured from the Scoliosis Research Society SRS-30 QoL questionnaire.

METHODS

The minimum follow-up was 2 years. PFA and QoL were compared pre- and postoperatively. Statistical analysis used nonparametric Mann-Whitney and Wilcoxon Signed Rank tests, Chi-square tests to compare proportions, and bivariate correlations with Spearman's coefficients.

RESULTS

A decreasing PFA correlated with less pain (r = ?0.56, p?=?.010), improved function (r = ?0.51, p?=?.022) and better self-image (r = ?0.46, p?=?.044) postreduction. Reduction decreased PFA by 5.1° (p?=?.002), whereas in situ fusion did not alter PFA significantly. Patients with normal preoperative PFA had similar postoperative QoL regardless of the type of surgery, except for self-image, which improved further with reduction (3.73 ± 0.49 to 4.26 ± 0.58, p?=?.015). Patients with abnormal preoperative PFA tended to have a higher QoL in all domains after reduction.

CONCLUSION

Decreasing PFA correlates with less pain, better function and self-image. Reduction of HGS decreases PFA. Reduction also relates to a better postoperative QoL when the preoperative PFA is abnormal. When the preoperative PFA is normal, in situ fusion is equivalent to reduction except for self-image, which is better improved after reduction.  相似文献

Background

Obesity is associated with an increased risk of atrial fibrillation (AF). Bariatric surgery results insubstantial long-term weight loss and the amelioration of several chronic comorbidities. We hypothesized that weightreduction with bariatric surgery would reduce the long-term incidence of AF.

Objectives

To assess the association between bariatric surgery and AF prevention.

Setting

University Hospital, United States.

Methods

All patients who underwent bariatric surgery at a single institution from 1985–2015 (n?=?3,572) were propensity score matched 1:1 to a control population of obese patients with outpatient appointments (n?=?45,750) in our clinical data repository. Patients with a prior diagnosis of AF were excluded. Demographics, relevant comorbidities, and insurance status were collected and a chart review was performed for all patients with AF. Paired univariate analyses were used to compare the two groups.

Results

After propensity score matching, 5,044 total patients were included (2,522 surgical, 2,522 non-surgical). There were no differences in preoperative body mass index (BMI) (47.1 vs 47.7 kg/m2, P?=?0.76) or medical comorbidities between groups. The incidence of AF was lower among surgical patients (0.8% vs 2.9%, P?=?0.0001). In patients ultimately diagnosed with AF, time from enrollment to development of AF did not differ between groups; however, surgical patients with AF experienced a significantly higher reduction in excess BMI compared to non-surgical patients with AF (57.9% vs ?3.8%, P<0.001).

Conclusion

The incidence of AF was lower among patients who underwent bariatric surgery compared to their medically managed counterparts. Weight reduction with bariatric surgery may reduce the long-term incidence of AF.  相似文献

BACKGROUND CONTEXT

Surgical treatment of cervical ossification of the posterior longitudinal ligament (OPLL) has a high risk of various complications. Anterior decompression with fusion (ADF) and laminoplasty (LAMP) are the most representative surgical procedures. However, few studies have compared the two procedures in terms of perioperative surgical complications.

PURPOSE

To compare the perioperative complications post-ADF and LAMP for cervical OPLL using a large national inpatient database.

STUDY DESIGN

A retrospective cohort study with propensity score matching analysis.

PATIENT SAMPLE

Overall, 8,718 (ADF/LAMP:1,333/7,485) patients who underwent surgery for cervical OPLL from April 1, 2010 to March 31, 2016 in hospitals using the diagnosis procedure combination were analyzed.

OUTCOME MEASURES

The occurrence of postoperative complications during hospitalization.

METHODS

We compared the perioperative systemic and local complications, reoperation rates, and costs between ADF and LAMP using propensity score matching analysis.

RESULTS

One-to-one matching resulted in 1,192 pairs of patients who underwent ADF and LAMP. The postoperative cardiovascular event rate was significantly higher (ADF/LAMP=1.9/0.8%, p=.013) in the ADF group. The incidence rates of dysphagia (similarly, 2.4/0.2%, p<.001), pneumonia (1.0/0.3%, p=.045), and spinal fluid leakage (2.4/0.4%, p<.001) were also higher in the ADF group, even after matching. The costs were also higher in the ADF group. However, surgical site infection (2.0/3.4%, p=.033) was significantly lower in the ADF group. No significant difference in the reoperation rates was found between the groups.

CONCLUSION

The present study, using a large nationwide database, demonstrated that perioperative complications were more common in the ADF group, but that surgical site infection (SSI) was more frequently observed in the LAMP group.  相似文献

Background

Early dumping is a poorly defined and incompletely understood complication after Roux-en-Y gastric (RYGB).

Objective

We performed a mixed-meal tolerance test in patients after RYGB to address the prevalence of early dumping and to gain further insight into its pathophysiology.

Setting

The study was conducted in a regional hospital in the northern part of the Netherlands.

Methods

From a random sample of patients who underwent primary RYGB between 2008 and 2011, 46 patients completed the mixed-meal tolerance test. The dumping severity score for early dumping was assessed every 30 minutes. A sum score at 30 or 60 minutes of ≥5 and an incremental score of ≥3 points were defined as indicating a high suspicion of early dumping. Blood samples were collected at baseline, every 10 minutes during the first half hour, and at 60 minutes after the start.

Results

The prevalence of a high suspicion of early dumping was 26%. No differences were seen for absolute hematocrit value, inactive glucagon-like peptide-1, and vasoactive intestinal peptide between patients with or without early dumping. Patients at high suspicion of early dumping had higher levels of active glucagon-like peptide-1 and peptide YY.

Conclusion

The prevalence of complaints at high suspicion of early dumping in a random population of patients after RYGB is 26% in response to a mixed-meal tolerance test. Postprandial increases in both glucagon-like peptide-1 and peptide YY are associated with symptoms of early dumping, suggesting gut L-cell overactivity in this syndrome.  相似文献

BACKGROUND CONTEXT

Both open surgical resection (OSR) and radiofrequency ablation (RFA) have been reported for spinal osteoid osteoma (OO).

PURPOSE

To verify the clinical safety and efficiency of RFA with OSR in treating spinal OO.

STUDY DESIGN

Retrospective cohort study.

PATIENT SAMPLE

Twenty-eight consecutive patients with spinal OO who underwent either RFA or OSR in our institute between September 2006 and December 2016.

OUTCOME MEASURES

The age, gender, lesion distribution, surgical time, estimated blood loss, complications, local recurrence, visual analogue scale (VAS), and the modified Frankel grade were documented.

METHODS

We retrospectively reviewed 28 patients with spinal OO who had been treated in our hospital from September 2006 to December 2016. Patients were followed at 3, 6, 12, and 24 months after the index surgery. The minimum follow-up period was 12 months. This study was funded by Peking University Third Hospital (Y71508-01) (¥ 400,000).

RESULTS

Twelve and 16 patients were treated with CT-guided percutaneous RFA and OSR, respectively. Spinal OO locations were cervical in 4, thoracic in 4, lumbar in 3, and sacral vertebra in 1 in the RFA group and cervical in 12, thoracic in 1, and lumber in 3 in the OSR group. RFA showed shorter operating time, less blood loss, and less in-hospital stay than open surgery [105.0 ± 33.8 minutes vs. 186.4 ± 53.5 minutes (p < .001), 1 (0 to 5) ml vs. 125 (30–1200) ml (p < .001) and 1 (1–3) days vs. 6 (3–10) days (p < .001), respectively]. At last follow-up, one patient underwent a secondary RFA for recurrence. VAS improvement was 7.5 (3–10) and 6.5 (4–9) (p = .945) in the RFA and OSR groups, respectively. The overall complication rate was 8.3% (1/12) and 18.8% (3/16) in the RFA and OSR groups, respectively.

CONCLUSIONS

If there is sufficient cerebrospinal fluid between the spinal OO lesion and spinal cord/nerve root (more than 1 mm), RFA is effective and safe for treatment of well-selected spinal OO, showing reduced operating time, blood loss, in-hospital stay, and complications compared to OSR. However, OSR is still recommended in cases with spinal cord/nerve root compression.  相似文献

Background

Sleeve gastrectomy (SG) is currently the most commonly performed bariatric procedure in the United States; however, it can be associated with development of de novo gastroesophageal reflux (GERD) or worsening of existing GERD. Preoperative esophagogastroduodenoscopy (EGD) and findings of esophagitis are commonly used as screening tool, but the alternative use of preoperative objective measurement of acid reflux has not been studied.

Objective

The aim of this study was to evaluate if preoperative objective measurement of acid reflux by using wireless pH monitoring (WPHM) could have an impact on surgical planning and outcomes.

Setting

Academic Center of Excellence.

Methods

Retrospective review of a prospectively collected database of 43 adult obese patients with reflux symptoms who underwent outpatient EGD and WPHM between September 2011 and September 2017.

Results

Change in planned surgical management from SG to Roux-en-Y-gastric bypass with the use of WPHM occurred in 21.0% (n?=?9) of patients. Only 2.3% (n?=?1) developed de novo GERD after SG. Nonerosive reflux disease was the most common esophageal condition on preoperative EGD. EGD, as a single diagnostic tool, appeared insufficient to diagnose acid reflux and help with the decision planning in this patient population.

Conclusions

Based on objective data obtained by measurement of GERD, using preoperative WPHM compared with preoperative EGD alone aids in a better patient selection for either SG or Roux-en-Y-gastric bypass. Our cohort with preoperative WPHM required no surgical conversions or revisions.  相似文献

BACKGROUND CONTEXT

Cervical laminectomy and fusion (CLF) is a common surgical option for multilevel cord compression. Postoperative C5 palsy occurrence after CLF has been a vexing problem for spine physicians. The posterior shift of the cord following laminectomy has been implicated as a major factor for postoperative C5 palsy, but attempts by spine surgeons to mitigate excessive shift while providing sufficient decompression have not been well reported.

PURPOSE

To compare the incidence of postoperative C5 palsy after performing selective blocking laminoplasty concurrently with CLF to those of conventional CLF.

STUDY DESIGN

A retrospective comparative study of prospectively collected data.

PATIENT SAMPLE

Of 116 cervical myelopathy patients with degenerative cervical myelopathy, ossification of the posterior longitudinal ligament, and multilevel disc herniation, 93 patients (69 in group A [CLF group] and 24 in group B [selective blocking laminoplasty with CLF, CLF-S group]) were included in the study.

OUTCOME MEASURES

The primary outcome measure was the occurrence of postoperative C5 palsy. Secondary end points included (1) clinical outcomes based on pain intensity, neck disability index (NDI), Japanese Orthopaedic Association (JOA) score, (2) radiologic outcomes including cervical alignment and fusion rate at 1 year and hardware complications, and (3) perioperative data (hospital stay, blood loss, and operative times).

METHODS

We compared the occurrence of postoperative C5 palsy, as well as clinical, radiologic, and surgical outcomes, between the two groups at 1-year follow-up.

RESULTS

The patients in both groups were statistically similar between the groups with respect to demographic characteristics such as age, sex, smoking status, body mass index, preoperative pathology, surgical segments, and the degree of the cervical lordosis. Postoperative C5 palsy developed in 9 of 61 patients (14%) in group A and in 0 of 24 patients (0%) in group B (CLF-S group) (p=.03). Postoperative neck pain, NDI, and JOA improvement were not significantly different between the two groups (p=.93, 0.90, and 0.79, respectively). Perioperative data did not differ significantly between the two groups.

CONCLUSIONS

This study showed that performing selective blocking laminoplasty might lead to reducing the incidence of postoperative C5 palsy in CLF surgery.  相似文献

Health literacy, defined as “the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions,” has been demonstrated to affect access to care and appropriate healthcare utilization.

PURPOSE

To determine the impact of health literacy in the evaluation and management of patients with chronic low back pain.

STUDY DESIGN

Cross sectional.

PATIENT SAMPLE

Patients seen at a multisurgeon spine specialty clinic.

OUTCOME MEASURES

Oswestry Disability Index, EQ-5D, and Numeric Rating Scales (0–10) for back and leg pain.

METHODS

The Newest Vital Sign (NVS) and Health Literacy Survey, Oswestry Disability Index, EQ-5D and pain scales were administered to patients undergoing evaluation and treatment for lumbar degenerative disease in the outpatient setting. Patients were surveyed regarding their use of medication, therapy, and pain management modalities.

RESULTS

Of 201 patients approached for participation, 186 completed the health literacy surveys. Thirty (17%) were assessed as having limited literacy, 52 (28%) as possibly having limited literacy and 104 (56%) having adequate literacy based on their NVS scores. The cohort with low NVS scores also had low Health Literacy Survey Scores. Patients with limited literacy had worse back and leg pain scores compared with patients with possibly limited literacy and adequate literacy. Patients with adequate health literacy were more likely to use medications (80% vs. 53%, p?=?.017) and were more likely to see a specialist (34% vs. 17%) compared with those with limited literacy. Patients with limited health literacy were not more likely to see a chiropractor (7% vs. 7%), but reported more visits (19 vs. 8).

CONCLUSIONS

Patients with lower health literacy reported worse back and leg pain scores, indicating either more severe disease or a fundamental difference in their responses to standard health-related quality of life measures. This study also suggests that patients with limited health literacy may underutilize some resources and overutilize other resources. Further study is needed to clarify these patterns, and to examine their impact on health status and clinical outcomes.  相似文献

BACKGROUND CONTEXT

Degenerative lumbar scoliosis (DLS) is an increasingly common spinal disorder of which current management is characterized by a substantial variety in treatment advice. To improve evidence-based clinical decision-making and increase uniformity and transparency of care, the Scoliosis Research Society established appropriateness criteria for surgery for DLS. In these criteria, however, the patient perspective was not formally incorporated. Since patient perspective is an increasingly important consideration in informed decision-making, embedding patient-reported outcome measures (PROMs) in the appropriateness criteria would allow for an objective and transparent patient-centered approach.

PURPOSE

To evaluate the extent that patient perspective is integrated into the appropriateness criteria of surgery for DLS.

STUDY DESIGN

Single center, retrospective, cohort study.

PATIENT SAMPLE

150 patients with symptomatic degenerative lumbar scoliosis.

Outcome Measures

The association between appropriateness for surgery and various PROMs [Visual Analogue Scale for pain, Short Form 36 (SF-36), Pain Catastrophizing Scale (PCS), Hospital Anxiety Depression Scale (HADS), and Oswestry Disability Index (ODI)].

METHODS

Medical records of all patients with symptomatic DLS were reviewed and scored according to the appropriateness criteria. To assess the association between the appropriateness criteria and the validated PROMs, analysis of variance was used to test for differences in PROMS for each of the three categories resulting from the appropriateness criteria. To assess how well PROMs can discriminate between appropriate and inappropriate, we used a logistic regression analysis. Discriminative ability was subsequently determined by computing the area under the curve (AUC), resulting from the logistic regression analysis. Spearman rank analysis was used to establish a correlation pattern between the PROMs used and the appropriateness criteria.

RESULTS

There was a significant association between the appropriateness of surgery and the PROMs. The discriminative ability for appropriateness of surgery for PROMs as a group was strong (AUC of 0.83). However, when considered in isolation, the predictive power of any individual PROMs was poor. The different categories of the appropriateness criteria significantly coincided with the PROMs used.

CONCLUSION

There is a statistically significant association between the appropriateness criteria of surgery for DLS and PROMs. Implementation of PROMs into the appropriateness criteria may lead to more transparent, quantifiable and uniform clinical decision making for DLS.  相似文献

Background

In bariatric surgery, preoperative very low-calorie diets (VLCD) may better meet the technical demands of surgery by shrinking the liver. However, diets may affect tissue healing and influence bowel anastomosis in an as-yet-undefined manner.

Objective

This randomized controlled trial aimed to examine the effect on collagen deposition in wounds in patients on a 4-week VLCD before laparoscopic gastric bypass.

Setting

University hospital.

Methods

The trial was undertaken in patients undergoing laparoscopic Roux-en-Y gastric bypass, with a control group (n?=?10) on normal diet and an intervention group (n?=?10) on VLCD (800 kcal) for 4 weeks. The primary outcome measured was expression of collagen I and III in skin wounds, with biopsies taken before and after the diet and 7 days postoperatively as a surrogate of anastomotic healing. Secondary outcome measures included liver volume and fibrosis score, body composition, operating time, blood loss, hospital stay, and complications.

Results

Patients in both groups were similar in age, sex, body mass index (53.4 versus 52.8 kg/m2), co-morbidities, liver volume, and body composition. Expression of mature collagen type I was significantly decreased in diet patients compared with controls after 4 weeks of diet and 7 days after surgery. This was significant decrease in liver volume (23% versus 2%, P?=?.03) but no difference in operating times (129 versus 139 min, P?=?.16), blood loss, length of stay, or incidence of complications.

Conclusions

Preoperative diets shrink liver volume and decrease expression of mature collagen in wounds after surgery. Whether the latter has a detrimental effect on clinical outcomes requires further evaluation.  相似文献
