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2.

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3.

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4.

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5.

PURPOSE
To characterize the gross, histologic, and systemic changes caused by implantation of metal fragments commonly used in commercial bullets into the intervertebral disc.BACKGROUND CONTEXT
Long-term complications of retained bullet fragments in the spine have been documented in the literature; however, the impact of different metal projectiles on the intervertebral disc has not been described. This study was performed to assess the local effects of the metallic bullet fragments on the intervertebral disc and their systemic effects regarding metal ion concentrations in serum and solid organs.STUDY DESIGN
Animal Model Study.METHODS
Funding for this project was provided by the Cervical Spine Research Society in the amount of $10,000. Copper, lead, and aluminum alloys from commercially available bullets were surgically implanted into sequential intervertebral discs in the lumbar spine of six canines. Kirschner wire implantation and a sham operation were performed as controls. Radiographs were performed to confirm the location of the bullets. Animals were sacrificed at 4, 6, and 9 months postimplantation. Whole blood, plasma, cerebrospinal fluid, kidney tissue, and liver tissue samples were analyzed for copper and lead concentrations. Histologic and gross samples were examined at the time of sacrifice.RESULTS
Significant tissue reactions were noted in the discs exposed to copper and lead. Copper resulted in significantly more severe disc degeneration than either the lead or aluminum alloy. In the short interval follow-up of this study, no statistically significant trend was observed in whole blood, plasma, cerebrospinal fluid, and tissue levels.CONCLUSION
This study demonstrates that the canine intervertebral disc is differentially susceptible to metallic fragments depending on the composition. Trends were noted for increasing levels of lead and copper in liver tissue samples although statistical significance could not be reached due to short time interval and small sample size. The metallic composition of retained fragments can be a determining factor in deciding on surgical intervention. 相似文献6.

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7.

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8.

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9.

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10.
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11.

Background
Though intestinal failure (IF) after bariatric surgery (BS) is uncommon, its prevalence is increasing. However, data on the outcomes for these patients are limited.Objectives
To analyze the outcomes of treatment for patients with IF after BS.Setting
University hospital.Methods
A single-center analysis (1991–2016) of outcomes according to treatment arms established by a multidisciplinary team.Results
Twenty-five IF patients were identified (median age 45 yr). BS was 92% Roux-en-Y gastric bypass. The major cause of IF was volvulus/internal hernia (72%). Median time from BS to IF was 48 months. Treatment arms were intestinal rehabilitation (IR, n?=?15), transplantation (TXP, n?=?5), and parenteral nutrition (PN, n?=?5). For IR, median bowel length was 60 cm. Forty-six percent ultimately discontinued PN. Twenty-seven percent were partially weaned PN and 27% failed IR. Common surgical rehabilitation was Roux-en-Y gastric bypass reversal and restoration of gastrointestinal continuity. The 5-year overall survival was 74%. For TXP, 7 patients were listed for TXP (5 initially and 2 after failed IR). Three underwent TXP, 2 isolated intestine and 1 isolated liver. Three were delisted (1 improvement and 2 death). For PN, 6 patients required long-term PN (5 initially and 1 after failed IR). Four patients are alive currently.Conclusions
IF after BS is an increasing problem facing IR centers. Internal hernia is the major cause. Surgical IR is the first-line therapy and affords the best outcome. TXP is reserved for rescuing patients who failed IR or develop PN complications. Long-term PN is suitable for patients in whom IR or TXP is impractical. 相似文献12.

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13.

BACKGROUND AND CONTEXT
The impact of underlying liver disease on surgical outcomes has been recognized in a wide variety of surgical disciplines. However, less empiric data are available about the importance of liver disease in spinal surgery.PURPOSE
To measure the independent impact of underlying liver disease on 30-day outcomes following surgery for the degenerative cervical spine.STUDY DESIGN
Retrospective comparative study.PATIENT SAMPLE
A cohort of 21,207 patients undergoing elective surgery for degenerative disease of the cervical spine from the American College of Surgeons National Surgical Quality Improvement Program.OUTCOME MEASURES
Outcome measures included mortality, hospital length of stay, and postoperative complications within 30 days of surgery.METHODS
The NSQIP dataset was queried for patients undergoing surgery for degenerative disease of the cervical spine from 2006 to 2015. Assessment of underlying liver disease was based on aspartate aminotransferase-to-platelet ratio index and Model of End-Stage Liver Disease-Sodium scores, computed from preoperative laboratory data. The effect of liver disease on outcomes was assessed by bivariate and multivariate analyses, in comparison with 16 other preoperative and operative factors.RESULTS
Liver disease could be assessed in 21,207 patients based on preoperative laboratory values. Mild liver disease was identified in 2.2% of patients, and advanced liver disease was identified in 1.6% of patients. The 30-day mortality rates were 1.7% and 5.1% in mild and advanced liver diseases, respectively, compared with 0.6% in patients with healthy livers. The 30-day complication rates were 11.8% and 31.5% in these patients, respectively, compared with 8.8% in patients with healthy livers. In multivariate analysis, the presence of any liver disease (mild or advanced) was independently associated with an increased risk of mortality (OR=2.00, 95% CI=1.12–3.55, p=.019), morbidity (OR=1.35, 95% CI=1.07–1.70, p=.012), and length of hospital stay longer than 7 days (OR=1.73, 95% CI=1.40–2.13, p<.001), when compared with 18 other preoperative and operative factors. Liver disease was also independently associated with perioperative respiratory failure (OR=1.80, 95% CI=1.21–2.68, p=.004), bleeding requiring transfusion (OR=1.43, 95% CI=1.01–2.02, p=.044), wound disruption (OR=2.82, 95% CI=1.04–7.66, p=.042), and unplanned reoperation (OR=1.49, 95% CI=1.05–2.11, p=.025).Conclusions
Liver disease independently predicts poor perioperative outcome following surgery for degenerative disease of the cervical spine. Based on these findings, careful consideration of a patient's underlying liver function before surgery may prove valuable in surgical decision-making, preoperative patient counseling, and postoperative patient care. 相似文献14.

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
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17.

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18.

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19.

Background
Among the population of morbidly obese people, super-super-obese (SSO) individuals (body mass index >60 kg/m2) present a treatment challenge for bariatric surgeons.Objectives
To compare the long-term outcomes between laparoscopic sleeve gastrectomy (SG) and laparoscopic Roux-en-Y gastric bypass (RYGB) and to evaluate the efficacy of SG as a stand-alone bariatric procedure for SSO patients.Setting
University hospital, Paris, France.Methods
We retrospectively reviewed the data outcomes of 210 SSO patients who underwent SG or RYGB between January 2000 and December 2011. The 6-year follow-up data were analyzed and compared.Results
Follow-up data at 6 years were collected for 57.1% and 52.1% of patients in the SG group and RYGB groups, respectively. Both procedures were effective at promoting weight loss. Most weight loss was achieved at 24 months with both procedures. The average percent excess weight loss and change in body mass index of SG versus RYGB showed no significant differences at the 4-year follow-up. Except for sleep apnea, RYGB showed slightly better resolution of the evaluated co-morbidities. The composite endpoint of major short-term adverse events (<30 d) occurred in 11.7% of patients with RYGB and 6.4% of those with SG (P?=?.02). Postoperative complications were seen in 26% of RYGB patients and 16.1% of SG patients.Conclusions
SG as a primary procedure for SSO patients remains effective even though RYGB achieves better midterm outcomes. SG can be proposed as the primary-option p+rocedure. Further investigations are needed to identify the ideal procedure for patients with symptoms of gastroesophageal reflux disease. 相似文献20.
