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2.
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3.

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4.

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5.
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6.

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7.
BACKGROUND CONTEXT
Fungal spinal epidural abscess (FSEA) is a rare entity with high morbidity and mortality. Reports describing the clinical features, diagnosis, treatment, and outcomes of FSEA are scarce in the literature.PURPOSE
This study aimed to describe the clinical features, diagnosis, treatment, and outcomes of FSEA.STUDY DESIGN
This study is designed as a retrospective clinical case series.PATIENT SAMPLE
A continuous series of patients with the diagnosis of FSEA who presented at our institution from 1993 to 2016.METHODS
We reviewed the electronic medical records of patients with SEA who were treated within our hospital system from 1993 to 2016. We only included SEA cases that were due to fungi. We also reviewed FSEA cases in the English language literature from 1952 to 2017 to analyze the features of FSEA.RESULTS
From a database of 1,053 SEA patients, we identified 9 patients with FSEA. Aspergillus fumigatus was isolated from 2 (22%) patients, and Candida species were isolated from 7 (78%). Focal spine pain, neurologic deficit, and fever were demonstrated in 89%, 50%, and 44% of FSEA cases, respectively. Five of nine cases involved the thoracic spine, and eight were located anterior to the thecal sac. Three cases had fungemia, six had long symptom duration (>2 weeks) prior to presentation, seven had concurrent immunosuppression, and eight had vertebral osteomyelitis. Additionally, one case had residual motor deficit at last follow-up, one had S1 sensory radicular symptoms, two suffered recurrent FSEA, two died within hospitalization, and two died within 90 days after discharge.CONCLUSIONS
In summary, the classic diagnostic triad (focal spine pain, neurologic deficit, and fever) is not of great clinical utility for FSEA. Biopsy, intraoperative tissue culture, and blood culture can be used to diagnose FSEA. The most common pathogens of FSEA are Aspergillus and Candida species. Therefore, empiric treatment for FSEA should cover these species while definitive identification is pending. FSEA is found in patients with poor baseline health status, which is the essential reason for its high mortality. 相似文献8.

BACKGROUND
In modern clinical research, the accepted minimum follow-up for patient-reported outcome measures (PROMs) after lumbar spine surgery is 24 months, particularly after fusion. Recently, this minimum requirement has been called into question.PURPOSE
We aim to quantify the concordance of 1- and 2-year PROMs to evaluate the importance of long-term follow-up after elective lumbar spine surgery.STUDY DESIGN
Retrospective analysis of data from a prospective registry.PATIENT SAMPLE
We identified all patients in our prospective institutional registry who underwent degenerative lumbar spine surgery with complete baseline, 12-month, and 24-month follow-up for ODI and numeric rating scales for back and leg pain (NRS-BP and NRS-LP).OUTCOME MEASURES
Oswestry Disability Index (ODI) and NRS-BP and NRS-LP at 1 year and at 2 years.METHODS
We evaluated concordance of 1- and 2-year change scores by means of Pearson's product-moment correlation and performed logistic regression to assess if achieving the minimum clinically important difference (MCID) at 12 months predicted 24-month MCID. Odds ratios (OR) and their 95% confidence intervals (CI), as well as model areas-under-the-curve were obtained.RESULTS
A total of 210 patients were included. We observed excellent correlation among 12- and 24-month ODI (r?=?0.88), NRS-LP (r?=?0.76) and NRS-BP (r?=?0.72, all p <.001). Equal results were obtained when stratifying for discectomy, decompression, or fusion. Patients achieving 12-month MCID were likely to achieve 24-month MCID for ODI (OR: 3.3, 95% CI: 2.4–4.1), NRS-LP (OR: 2.99, 95% CI: 2.2–4.2) and NRS-BP (OR: 3.4, 95% CI: 2.7–4.2, all p <.001) with excellent areas-under-the-curve values of 0.81, 0.77, and 0.84, respectively. Concordance rates between MCID at both follow-ups were 87.2%, 83.8%, and 84.2%. A post-hoc power analysis demonstrated sufficient statistical power.CONCLUSIONS
Irrespective of the surgical procedure, 12-month PROMs for functional disability and pain severity accurately reflect those at 24 months. In support of previous literature, our results suggest that 12 months of follow-up may be sufficient for evaluating spinal patient care in clinical practice as well as in research. 相似文献9.

Background
For a number of years the laparoscopic adjustable gastric band has been one of the leading bariatric procedures with good short-term outcomes. However, inadequate weight loss, weight regain, and other band-related complications in the long term led to an increase in revisional Roux-en-Y gastric bypass (RYGB) procedures. Lengthening the biliopancreatic limb, a relatively simple and safe adjustment of the standard technique, could improve the results of the revisional procedure.Objectives
The aim of this randomized controlled trial was to evaluate the effect of a long biliopancreatic limb RYGB (LBP-GB) and standard RYGB (S-GB) as revisional procedure after laparoscopic adjustable gastric band.Setting
General hospital specialized in bariatric surgeryMethods
One hundred forty-six patients were randomized in 2 groups; 73 patients underwent an S-GB (alimentary/biliopancreatic limb 150/75 cm), and 73 patients underwent LBP-GB (alimentary/biliopancreatic limb 75/150). Weight loss, remission of co-morbidities, quality of life, and complications were assessed during a period of 4 years.Results
Baseline characteristics between the groups were comparable. At 48 months the follow-up rate was 95%. Mean total weight loss after 24 months was 27% for LBP-GB versus 22% S-GB (P?=?.015); mean total weight loss after 48 months was 23% and 18%, respectively (P?=?.036). No significant differences in other parameters were found between the groups.Conclusions
A LBP-GB as revisional procedure after a failing laparoscopic adjustable gastric band improves short- and long-term total weight loss compared with an S-GB. Together with future modifications this technically simple adjustment of the RYGB could significantly improve disappointing results after revisional surgery. 相似文献10.

BACKGROUND CONTEXT
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11.

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12.

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13.

Objectives
To evaluate the feasibility and outcomes of a nonopioid (NOP) perioperative pain management protocol for patients undergoing robot-assisted radical cystectomy (RARC).Materials and Methods
We prospectively included 52 consecutive patients undergoing RARC at our institution for bladder cancer. Patients received a multimodal pain management protocol, including a combination of nonopioid pain medications and regional anesthesia. For comparison, we retrospectively included 41 consecutive patients who received the same procedure before implementation of the NOP protocol.Results
There was no significant difference in demographic and perioperative characteristics between the two groups. Patients included in the NOP protocol received a much lower dose of postoperative morphine milligram equivalents (2.5 [IQR: 0–23] vs. 44 [14.5–128], P < 0.001), with no difference in pain scores. In the NOP protocol, the median time to regular diet was significantly shorter (4days [IQR: 3–5] vs. 5days [IQR: 4–8], P?=?0.002) and the length of stay was 2days shorter compared to the control group (5days [IQR: 4–7] vs. 7days [IQR: 6–11], P < 0.001). When evaluating the direct costs within 30days after initial surgery, the NOP protocol was associated with an 8.6% reduction as compared to the control group (P?=?0.032). In multivariate analysis, the receipt of the NOP protocol was a significant predictor of a length of stay <7days after RARC (OR: 12.09; 95% CI: 1.70–140; P?=?0.023).Conclusions
The prospective implementation of a NOP protocol for patients undergoing RARC is feasible, allowing for minimal narcotic usage and provides benefits to patients, institutions, and population. 相似文献14.
Selective blocking laminoplasty in cervical laminectomy and fusion to prevent postoperative C5 palsy
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15.

Background
Numerous studies have shown that Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) differently affect metabolic disorders associated with obesity. While bariatric surgery has been shown to improve nonalcoholic fatty liver disease, very few studies have compared liver parameters after both procedures.Objectives
To compare the evolution of liver parameters after SG and RYGB and their relationships with improvement of metabolic disorders.Methods
Metabolic parameters and abdominal ultrasonography were recorded before and 1 year after bariatric surgery in all patients who underwent SG or RYGB between 2004 and 2016 in our institution.Setting
University hospital, Colombes, France.Results
Five hundred thirty-three patients (15% men, age 43 ± 11 yr) were analyzed, including 326 who underwent RYGB and 207 who underwent SG. Before surgery, body mass index (44.7 ± 5.7 versus 44.4 ± 7.4 kg/m²) and metabolic parameters were not significantly different. One year after surgery, RYGB induced greater weight loss (31.9 ± 7.7 versus 28.6 ± 8.3 %, P < .001). Metabolic parameters improved in both groups, but fasting insulin, low-density lipoprotein cholesterol, C-reactive protein, and ferritin were lower after RYGB (P < .001). In contrast, transaminases were higher after RYGB compared with SG (alanine aminotransferase: 31.6 ± 18.7 versus 22.6 ± 7.7 IU/L; P < .001). The persistence of alanine aminotransferase >34 IU/L (27% versus 7% of patients, P < .001) was independent of the persistence of steatosis on ultrasonography (39% versus 37% of patients) 1 year after RYGB and SG, respectively.Conclusion
Despite a greater improvement of metabolic disorders, RYGB has less beneficial effect on liver parameters compared with SG. Further studies are required to define the mechanisms explaining these differences between both procedures. 相似文献16.

Background
Biliopancreatic diversion with duodenal switch (DS) is known to be superior in weight loss to other bariatric procedures, but with the disadvantage of increased complication rates. Single-anastomosis duodenal-ileal bypass (SADI-S) is reported to have similar weight loss with lower complication rates compared with traditional DS.Objectives
The aim of this study was to compare weight loss and complication rate between SADI-S and double-anastomosis DS at a single institution.Setting
Academic hospital, United States.Methods
A retrospective chart review was performed on 185 patients who underwent laparoscopic or robot-assisted laparoscopic DS between March 1, 2015 and December 10, 2017. A total of 111 patients had SADI-S, and 74 patients underwent double-anastomosis DS.Results
Baseline patient characteristics were comparable between the 2 groups. The mean preoperative body mass index was 56.3 kg/m2 and 54.4 kg/m2 in SADI-S and double-anastomosis DS patients, respectively. Thirteen (11.7%) and 4 (5.4%) patients were readmitted within 30 days after SADI-S and double-anastomosis DS, respectively (P?=?.16). Percentage of total weight loss was 22.0%, 38.5%, and 44.2% in the SADI-S group and 20.2%, 38.0%, and 48.4% in the double-anastomosis DS group at 6, 12, and 24 months, respectively. The majority of patients had vitamin A and E levels in the normal range. However, 40% to 60% of the patients had low levels of vitamin D after the procedure.Conclusions
SADI-S and double-anastomosis DS are comparable in terms of weight loss and complication rate. However, close nutritional follow-up is warranted for both procedures. 相似文献17.

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18.

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19.

Background
The repair of retracted flexor tendons is a challenging problem for hand surgeons. The tendon stump should be handled in an atraumatic manner because any microtrauma to the sheath and tendon can lead to poor functional outcomes.Methods
Twenty-three patients with flexor zone 2 injuries and intraoperative finding of retracted tendons were randomly divided into two groups: endoscopic retrieval group and proximal incision group. A flexible endoscope and a flexible grasping forceps were used for endoscopic retrieval of the retracted flexor tendons. The groups were compared in terms of infection rate, neurovascular complications, regional pain, total range of active motion (TAM) and functional outcomes.Results
Age, gender, average preoperative pain and general pain perception scores were similar between the two groups. We found a significantly shorter duration of operation and better pain scores at 1–2 weeks in the endoscopic group than in the other group (p?=?0.002 and p?=?0.020, respectively). A significant difference in TAM was demonstrated between the groups at 3 to 5 weeks (p?=?0.003).Conclusion
The surgical procedure presented here has the advantages of direct visibility of the proximal tendon end and retrieval in an atraumatic manner, with better results and decreased morbidity. It is a promising approach and can be used as a routine procedure in retracted tendon cases. 相似文献20.
