PURPOSE: The purpose of this prospective clinical study was to assess quality of life (QOL) and impact of seizure status on QOL in patients with extratemporal epilepsy after surgery. PATIENTS AND METHODS: Twenty-three consecutive patients who had been operated due to extratemporal epilepsy were included in this study. Quality of Life Inventory in Epilepsy-10 (QOLIE-10) questionnaire was completed by all patients before 6 months and 2 years after surgery. Results obtained from short- and long-term follow-up were compared to baseline. Furthermore, patients who were seizure-free since surgery and those who had seizure were also compared in terms of outcome in QOL after surgery. RESULTS: All patients showed significantly improved QOL in both short- and long-term follow-ups compared to preoperative status regardless of seizure status (p<0.001). Seizure-free patients showed better QOL than those of patients who continued to have seizure during postoperative period. Furthermore, improved QOL was correlated with seizure status and shorter duration of epilepsy (p=0.001). CONCLUSION: Our findings showed that improved QOL is related to postoperative seizure status. However, future clinical studies including larger population of patients with extratemporal epilepsy are required to elucidate the role of other factors.  相似文献

PurposeWe analyzed the long-term postoperative outcome and possible predictive factors of the outcome in surgically treated patients with refractory extratemporal epilepsy.MethodsWe retrospectively analyzed 73 patients who had undergone resective surgery at the Epilepsy Center Brno between 1995 and 2010 and who had reached at least 1 year outcome after the surgery. The average age at surgery was 28.3 ± 11.4 years. Magnetic resonance imaging (MRI) did not reveal any lesion in 24 patients (32.9%). Surgical outcome was assessed annually using Engel's modified classification until 5 years after surgery and at the latest follow-up visit.ResultsFollowing the surgery, Engel Class I outcome was found in 52.1% of patients after 1 year, in 55.0% after 5 years, and in 50.7% at the last follow-up visit (average 6.15 ± 3.84 years). Of the patients who reached the 5-year follow-up visit (average of the last follow-up 9.23 years), 37.5% were classified as Engel IA at each follow-up visit. Tumorous etiology and lesions seen in preoperative MRI were associated with significantly better outcome (p = 0.035; p < 0.01). Postoperatively, 9.6% patients had permanent neurological deficits.ConclusionSurgical treatment of refractory extratemporal epilepsy is an effective procedure. The presence of a visible MRI-detected lesion and tumorous etiology is associated with significantly better outcome than the absence of MRI-detected lesion or other etiology.  相似文献

Purpose: The present study aims to describe the cognitive profile of children with medically refractory extratemporal epilepsies who undergo focal surgery and to identify determinants for preoperative and postoperative cognitive level. Methods: This is a retrospective cohort study. Children who underwent operations between 1997 and 2008 with a focal lesion in frontal, parietal, or occipital cortices and with a presurgical or postsurgical cognitive evaluation, were eligible for the study. Key Findings: Sixty‐six children (53% male) with a mean age of 9.3 ± 8.8 years were enrolled. The overall full‐scale IQ (FSIQ) at cognitive testing was 77.4 ± 44.4 before surgery. Children did not show any significant change in their FSIQ after surgery. Duration of presurgical epilepsy, age at epilepsy onset, etiology, and gender were found to be independently associated with lower FSIQ before surgery. Presurgical cognitive level was the only factor independently associated with postsurgical FSIQ. Overall, 51.5% of children who underwent surgery were seizure‐free; however, the good postsurgical epilepsy control did not seem to influence the cognitive outcome. Significance: Children with extratemporal lobe epilepsy are below the normal cognitive level range. Intellectual abilities of children undergoing surgery are determined independently by presurgical factors and surgery does not seem to affect the cognitive level in the postsurgical period, even for those who become free from clinical seizures.  相似文献

Objective

To assess the prognostic value of postoperative EEG in patients surgically treated for drug-resistant extra-temporal lobe (ET) epilepsy.

Methods

We studied 63 consecutive patients with ET epilepsy who underwent epilepsy surgery and were followed up for at least 2 years (mean duration of follow-up 6.2 ± 2.3 years, range 2–12). Follow-up evaluations were performed 2, 12, and 24 months after surgery, and included standard EEG (at 2 months) and long-term video-EEG monitoring during both wakefulness and sleep (at 12 and 24 months). Seizure outcome was determined at each follow-up evaluation, and then at yearly intervals. Patients who were in Engel Class I at the last contact were classified as having a good outcome.

Results

Seizure outcome was good in 39 patients (62%). The presence of interictal epileptiform discharges (IED) in postoperative EEG at each time point was found to be associated with poor outcome. The strength of this association was greater for awake plus sleep recording as compared with awake recording alone. In a multiple regression model including all pre- and post-operative factors identified as predictors of outcome in univariate analysis, the presence of early (2 months after surgery) EEG epileptiform abnormalities was found to be independently associated with poor seizure outcome.

Conclusions

Postoperative IED may predict long-term outcome in patients undergoing resective surgery for ET epilepsy.

Significance

The increase in risk of unfavourable outcome associated with EEG epileptiform abnormalities detected as early as two months after surgery may have substantial practical importance. Serial postoperative EEGs including sleep recording may add further predictive power and help making decision about antiepileptic drug discontinuation.  相似文献

Improved quality of life (QoL) is an important outcome goal following epilepsy surgery. This study aims to quantify change in QoL for adults with drug-resistant epilepsy (DRE) who undergo epilepsy surgery, and to explore clinicodemographic factors associated with these changes. We conducted a systematic review and meta-analysis using Medline, Embase, and Cochrane Central Register of Controlled Trials. All studies reporting pre- and post-epilepsy surgery QoL scores in adults with DRE via validated instruments were included. Meta-analysis assessed the postsurgery change in QoL. Meta-regression assessed the effect of postoperative seizure outcomes on postoperative QoL as well as change in pre- and postoperative QoL scores. A total of 3774 titles and abstracts were reviewed, and ultimately 16 studies, comprising 1182 unique patients, were included. Quality of Life in Epilepsy Inventory–31 item (QOLIE-31) meta-analysis included six studies, and QOLIE-89 meta-analysis included four studies. Postoperative change in raw score was 20.5 for QOLIE-31 (95% confidence interval [CI] = 10.9–30.1, I2 = 95.5) and 12.1 for QOLIE-89 (95% CI = 8.0–16.1, I2 = 55.0%). This corresponds to clinically meaningful QOL improvements. Meta-regression demonstrated a higher postoperative QOLIE-31 score as well as change in pre- and postoperative QOLIE-31 score among studies of cohorts with higher proportions of patients with favorable seizure outcomes. At an individual study level, preoperative absence of mood disorders, better preoperative cognition, fewer trials of antiseizure medications before surgery, high levels of conscientiousness and openness to experience at the baseline, engagement in paid employment before and after surgery, and not being on antidepressants following surgery were associated with improved postoperative QoL. This study demonstrates the potential for epilepsy surgery to provide clinically meaningful improvements in QoL, as well as identifies clinicodemographic factors associated with this outcome. Limitations include substantial heterogeneity between individual studies and high risk of bias.  相似文献

PURPOSE: It is difficult to validly assess the long-term effect of epilepsy surgery. Here, this is attempted by comparing the outcome of surgically treated pharmacoresistant epilepsy patients to three different nonoperated comparison groups regarding seizure control, antiepilepsy drug (AED) usage, and health related quality of life (QOL). METHODS: One hundred thirty-one operated patients (group 1, mean follow-up since presurgical assessment 6.9 years), 105 patients awaiting presurgical assessment (group 2, mean follow-up after assignment to waiting list 0.8 years), 99 patients considered to be presurgical candidates who chose to withdraw from waiting for presurgical assessment (group 3, mean follow-up after assignment to waiting list 5.5 years), and 49 patients who were not deemed to be eligible for surgery after comprehensive assessment (group 4, mean follow-up since presurgical assessment 6.5 years) were studied. The patients completed a questionnaire on seizures, AED usage, and QOL (ESI-55). RESULTS: The surgical patients had a better outcome than all three comparison groups regarding seizure frequency, seizure freedom rate, and number of AEDs used. They scored higher than groups 2, 3, and 4 on 7/11, 6/11, and 3/11 ESI-55 domains, respectively. CONCLUSIONS: The superior long-term outcome of the operated patients was most marked if compared to the patients awaiting surgery. This is compatible with the assumption that patients present for presurgical candidacy selection and assessment at a "nadir" of their disease course. After several years, a regression to the mean occurs which reduces (but does not abolish) the differences between nonoperated and operated patients.  相似文献

Introduction This review summarizes some patterns of pre-surgical evaluation and surgical treatment of extratemporal epilepsy in pediatric patients with medically refractory seizures, whose ictal behavior is variable. The most effective treatment for intractable partial epilepsy is a focal cortical resection with excision of the epileptogenic zone (the area of ictal onset and initial seizure propagation). This might be risky, though, in the case of a widespread lesion, sometimes encroaching one or more lobes, given the risk to the functional cerebral cortex. An anterior temporal lobectomy might prove more effective then in preventing seizures with fewer potential complications. If partial extratemporal epilepsy is associated with pharmaco-resistant seizures, the preoperative evaluation and operative strategy are determined according to the epileptogenic zone and to the relationship between a substrate-directed disorder and eloquent areas. The pediatric treatment of extratemporal epilepsy is aimed at controlling the seizures, avoiding morbidity, and improving the patient’s quality of life through psychosocial integration. Since the immature brain is more plastic than when mature, the recovery of functions after surgery is greater in children than in adults.Recommendation Early surgery is recommended for children with intractable epilepsy, and is now accepted as an important therapeutic modality also for children with chronic epilepsy.Conclusion Technological advances in the last two decades, mainly in neuroimaging, have led many medical centers to consider surgical treatment of epilepsy, accuracy being granted by MRI-based neuronavigation systems—an interface between the lesion seen in the preoperative magnetic resonance imaging (MRI) and the operative field, often invisible to the surgeon.  相似文献

PurposeResection of the seizure focus leads to sustained seizure-freedom in intractable focal epilepsy in up to 80% of selected populations. However, surgery fails to help in a considerable proportion of patients. Reevaluation and reoperation may be considered in a selected group of patients with an unfavorable postsurgical outcome. Here, we reviewed 15 case series on reoperation after failed resective epilepsy surgery in adults in order to identify factors associated with a good chance of benefitting from a second operation.MethodsLiterature review of case series describing the outcome of epilepsy surgical re-operations.ResultsOverall, 3.8–14% of all patients who had resective epilepsy surgery underwent a second operation. A total of 402 reoperated patients were included. Reoperation was performed in average between 2 and 5.5 years after the first surgery. 36.6% of all patients were seizure-free with a minimal follow-up of 6 months to 4 years after the second operation. Postsurgical complications were observed in 13.5% and mainly consisted of visual field defects and, less frequently, of hemiparesis. The causes of failed first epilepsy surgery were heterogeneous and included incorrect localization or incomplete resection of the seizure focus, presence of additional seizure foci or progression of the underlying disease. Some features appear to indicate successful reoperation, such as concordance of postsurgical imaging and electroclinical findings as well as absence of brain trauma and cerebral infection prior to epilepsy onset.ConclusionReoperation after thorough assessment of all available clinical, imaging and EEG findings can be an efficacious and reasonably safe treatment option which can achieve sustained seizure control after failed resective epilepsy surgery.  相似文献

PURPOSE: To examine long-term seizure and quality-of-life outcome in a homogeneous group of patients after temporal lobectomy with pathologically proven hippocampal sclerosis (HS). Previous research has had limited follow-up (generally <2 years) and has grouped patients across multiple pathologies. METHODS: Fifty consecutive patients were identified as having had a temporal lobectomy for the treatment of temporal lobe epilepsy at Royal Melbourne Hospital with pathologically proven HS and >or=2 years' follow-up. All patients were sent a postal survey concerning seizure activity, quality of life (QOLIE-89), and antiepileptic drug (AED) use. The mean follow-up was 5.8 years (range, 2-9.2). RESULTS: The rate of complete postoperative seizure freedom was 82% at 12 months, 76% at 24 months, and 64% at 63 months (no further seizure recurrences observed after this time). A class I seizure outcome was achieved by 83.3% of patients. Patients with better seizure outcome had significantly better quality of life (Kendall's tau =-234, p < 0.01). Seizure recurrence was associated with a reduction in AED intake or absorption in five (29%) of 17 cases, including three of the five patients with a first seizure recurrence after 24 months after surgery. CONCLUSIONS: Temporal lobectomy provides continued long-term seizure control in the majority of patients with HS. However, patients remain at risk of seizure recurrence >or=2 years after surgery. Long-term quality of life is dependent on seizure outcome.  相似文献

Aim The aim of the study was evaluation of surgical treatment of epilepsy measured by changes in quality of life (QOL) and in seizure frequency and severity.Materials and methods Examined group consists of 24 boys and 9 girls. We performed corpus callosotomy, lesionectomy, vagal nerve stimulation, temporal lobectomy and multiple subpial transections. Age at surgery ranged from 5 months to 19 years, with mean follow-up of 11.9 months. QOL was evaluated on the basis of the questionnaire created by us, in which parents were asked to assess the following variables before and after the surgical procedure: communication, socialization, daily living skills, movement abilities and behavioural problems. The seizure frequency was assessed with the Engel’s scale, the modified Engel’s scale and the Seizure Scoring System. Clinical state of all the patients was evaluated as well.Results There were no patients with stable and worsening QOL status. In the whole group treated with callosotomy, the considerable improvement in QOL concerned 36.4% of cases. In more than 95% of cases, the reduction in seizures frequency is greater than 75%. In more than 43% of patients, there are no seizures after surgery.Conclusions Surgical treatment of intractable epilepsy is an effective method in terms of both seizure control and QOL improvement. Our results indicate the improvement in QOL of all operated patients. The improvement in QOL was accompanied by decrease in frequency and ‘positive’ changes in morphology of seizures. Improvement in QOL, as equivalent to seizure reduction rate, may influence further differentiation of qualification methods and surgical procedures of epilepsy.  相似文献

Purpose: The short‐term efficacy and safety of epilepsy surgery relative to medical therapy has been established, but it remains underutilized. There is a lack of data regarding the long‐term seizure‐control rates and quality of life outcomes after epilepsy surgery. This study represents the longest follow‐up study to date, with a mean follow‐up duration of 26 years. Methods: We studied the seizure and health‐related quality of life outcomes of patients who underwent epilepsy surgery by Dr. Sidney Goldring from 1967 to 1990. Retrospective clinical chart reviews gathered perioperative data and surveys obtained follow‐up data. Seizure outcome was evaluated using the Engel classification system. Key Findings: Of 361 patients, 117 (32.4%) completed follow‐up interviews. Fifty‐six patients (48%) were Engel class I. Mean overall Quality of Life in Epilepsy (QOLIE‐31) questionnaire score for the cohort was 68.2 ± 16. Eighty percent of patients reported their overall quality of life now as being better than before surgery. Seizure freedom was associated with better quality of life. We did not observe a statistically significant association between postoperative complications and long‐term outcome. Patients who underwent temporal lobe resection achieved better seizure outcomes than those who underwent other types of procedures. Astatic seizures and bilateral surgery were associated with a worse Engel class outcome. Significance: Our study demonstrates that the beneficial effects of epilepsy surgery are sustained over decades, and that these beneficial effects are correlated with an improved quality of life. The confirmation of its durability makes us optimistic that the outcomes from modern epilepsy surgery will be even better and that our present enthusiasm for this treatment modality is not misplaced.  相似文献

Purpose: Both neurobiologic and psychosocial factors have been proposed to account for the high prevalence of depression surrounding epilepsy surgery. Using a prospective longitudinal approach, this study aimed to profile the evolution of depression after epilepsy surgery at multiple time points, including early and longer‐term follow‐up. We also sought to identify neurobiologic and psychosocial predictors of depression before and after surgery, including whether patients undergoing mesial temporal lobe resection (MTR) were at greater risk of depression than patients undergoing nonmesial temporal lobe resection (NMTR). Methods: Sixty patients undergoing epilepsy surgery (38 MTR, 22 NMTR) for the treatment of medically intractable seizures were assessed preoperatively and at 1, 3, 6, and 12 months postoperatively in the Comprehensive Epilepsy Program of Austin Health. The diagnosis of depression was based on DSM‐IV criteria for major depressive disorder, as assessed from a mental state examination. The Austin CEP Interview was used to obtain a detailed psychosocial assessment of each patient and family members. Key Findings: Before surgery, 43% of patients had a lifetime prevalence of depression, with no difference between the proportion of patients in the MTR (40%) and NMTR groups (50%). Predictive factors included a family history of psychiatric illness (p = 0.015) and financial dependence of either family members or government income benefits (p = 0.024). Discriminant function analysis indicated that these factors classified 69% of cases correctly (p = 0.006, partial η2 = 0.06). In the 12 months following surgery, 37% of MTR and 27% of NMTR patients experienced major depression, with no significant difference between the two groups. The majority of depressed patients (70%) were diagnosed in the first 3 months and in 65% of diagnosed cases, the depression persisted for at least 6 months within the follow‐up period. The pattern of recurrent and de novo depression differed significantly between the groups, with 13% of MTR patients developing de novo major depression in comparison to no NMTR patients (p = 0.05). A preoperative history of depression (p = 0.003) and poor postoperative family dynamics (1 month, p < 0.001; 3 months, p = 0.007; 6 months, p = 0.021; 12 months, p = 0.097) were predictive of depression after surgery. These factors correctly classified 78% of cases (p = 0.000, partial η2 = 0.19). Significance: The findings of this study confirm high rates of major depression before and after epilepsy surgery, the etiology of which is multifactorial. They highlight the need for thorough assessment and diagnosis before surgery, as well as the provision of routine follow‐up and psychological support, particularly early after surgery. When estimating level of risk for depression, patients should be counseled about the role of both neurobiologic and psychosocial factors. Before surgery, these include a family history of psychiatric illness and financial dependence, whereas poor family adjustment to life after surgery and a patient preoperative history of depression were risk factors for postoperative depression. Finally, disruption to mesial temporal structures known to play a role in mood via MTR may place patients at increased risk of new‐onset depression after surgery.  相似文献

OBJECTIVES: To evaluate the significance of exclusively unifocal, unilateral, interictal epileptiform patterns on scalp electroencephalography (EEG) in surgical candidates with medically intractable extratemporal epilepsy. METHODS: We reviewed 126 patients with refractory extratemporal partial seizures who underwent epilepsy surgery at our center. All were followed for at least 2 years after resections. Surgery was based on ictal EEG recordings. We examined ictal onsets and surgical outcome in subjects whose preoperative, interictal scalp EEGs during long-term monitoring (LTM) demonstrated only unilateral, well-defined focal discharges, and outcome in patients whose interictal EEGs during LTM showed bilateral, non-localized, or multifocal epileptiform patterns. RESULTS: We found that 26 subjects exhibited only unilateral, unifocal, interictal epileptiform patterns. In all 26 cases (100%) clinical seizures arose from the regions expected by the interictal findings (P<0.0001, Sign test). At last follow-up 77% (20/26) of these patients were seizure-free, while 23% (6/26) had >75% reduction in seizures. This compares to the remaining patients, of whom 34% (34/100) were seizure-free, 41% (41/100) had >75% reduction in seizures, and 25% (25/100) had <75% reduction in seizures (P=0.0001, Fisher's Exact test). CONCLUSIONS: Strictly unifocal, interictal epileptiform patterns on scalp EEG, though seen in a minority of subjects, may be an important, independent factor in evaluating subjects with intractable extratemporal, localization-related epilepsy for surgical therapy. This finding is highly predictive of both ictal onsets and successful postsurgical outcome.  相似文献

PURPOSE: Patients with intractable epilepsy, operated for extratemporal epileptogenic foci, have often been found to have poorer surgical outcome compared with those with temporal lobe foci. The objective of this study is to assess the surgical outcome in patients with extratemporal foci, operated at the All India Institute of Medical Sciences (AIIMS), New Delhi. METHODS: Patients of intractable epilepsy with extratemporal foci on detailed investigation constituted the study group. They were evaluated by the 'Comprehensive Epilepsy Care Team' at the AIIMS with detailed clinical assessment, interictal EEGs, video-EEG studies, magnetic resonance imaging (MRI) with special sequences tailored for evaluation of the temporal lobes and for cortical dysplasias and single photon emission computerised tomography (SPECT) studies. Intraoperative electrocorticography was obtained in some patients. Outcome was assessed on follow-up, and graded according to Modified Engel's Grading System. RESULTS: Twenty-five patients (18 males, 7 females) with a mean age of 19.7 years (age range 7-45 years) were operated and assessed during the study period, for surgical outcome with a mean follow-up of 16.8 months (range 3 months to 6.5 years). Twenty patients (87%) were found to have a good outcome (Modified Engel's grades I and II), while three had poor outcome, one died and one was lost to follow-up. CONCLUSION: We found a good seizure outcome in patients who underwent resection of extratemporal epileptogenic foci, one of the reasons being presence of a lesion in all patients. Careful patient selection even with non-invasive investigations can aid in obtaining a good outcome in this group of patients.  相似文献
