Project description:BackgroundMicrodiscectomy is the most commonly performed spine surgery and the first transitioning for outpatient settings. However, this transition was never studied, in what comes to cost-utility assessment. Accordingly, this economic study aims to access the cost-effectiveness of outpatient lumbar microdiscectomy when compared with the inpatient procedure.MethodsThis is a cost utility study, adopting the hospital perspective. Direct medical costs were retrieved from the assessment of 20 patients undergoing outpatient lumbar microdiscectomy and 20 undergoing inpatient lumbar microdiscectomy Quality-adjusted life-years were calculated from Oswestry Disability Index values (ODI). ODI was prospectively assessed in outpatients in pre and 3- and 6-month post-operative evaluations. Inpatient ODI data were estimated from a meta-analysis. A probabilistic sensitivity analysis was performed and incremental cost-effectiveness ratio (ICER) calculated.ResultsOutpatient procedure was cost-saving in all models tested. At 3-month assessment ICER ranged from €135,753 to €345,755/QALY, higher than the predefined threshold of €60,000/QALY gained. At 6-month costs were lower and utilities were higher in outpatient, overpowering the inpatient procedure. Probabilistic sensitivity analysis showed that in 65% to 73% of simulations outpatient was the better option. The savings with outpatient were about 55% of inpatient values, with similar utility scores. No 30-day readmissions were recorded in either group.ConclusionThis is the first economic study on cost-effectiveness of outpatient lumbar microdiscectomy, showing a significant reduction in costs, with a similar clinical outcome, proving it cost-effective.

Project description:Background:Percutaneous endoscopic transforaminal discectomy (PETD) is regarded as a viable alternative option for upper lumbar disc herniation (LDH). However, few studies have evaluated PETD for upper LDH, and no study has compared the advantages of endoscopic procedures versus conventional surgery. The present study was aimed at comparing the surgical outcome and safety of PETD versus conventional open lumbar discectomy in the treatment of upper LDH. Methods:Data from 42 patients treated for upper LDH from July 2015 to July 2018 were retrospectively analyzed, including 21 patients treated with PETD (PETD group) and 21 patients treated with conventional posterior lumbar discectomy (open group). The two groups were compared regarding demographic information, physical examination, radiological evaluations, and perioperative indicators. The clinical outcomes were assessed in accordance with the Oswestry Disability Index (ODI), visual analog scale (VAS), and modified MacNab criteria. Results:The postoperative ODI and VAS scores were significantly improved in both groups compared with the preoperative baseline values (P < 0.001), and the satisfactory rate was 90.5% in both groups in accordance with the modified MacNab criteria. There were no significant differences between the two groups in the clinical outcomes and complication rate (P < 0.001), and the satisfactory rate was 90.5% in both groups in accordance with the modified MacNab criteria. There were no significant differences between the two groups in the clinical outcomes and complication rate (P < 0.001), and the satisfactory rate was 90.5% in both groups in accordance with the modified MacNab criteria. There were no significant differences between the two groups in the clinical outcomes and complication rate (. Conclusions:PETD has a similar outcome to the conventional surgical method for the treatment of upper LDH but provides the typical advantages of minimally invasive procedures such as reduced iatrogenic injury, minimal activity restrictions, and accelerated ambulation recovery postoperatively.

Project description:BackgroundFenestration discectomy, for symptomatic lumbar disc herniation, is the most common surgical procedure in spine surgery. It can be done by open or microscopic procedures. This study compared the results of fenestration microdiscectomy with open fenestration discectomy in the treatment of symptomatic lumbar disc herniation as a relation to the functional outcome, leg pain, back pain, hospital stay, returns to daily activity, cost, recurrence, reoperation and type of surgery for recurrent disc herniation.Methods60 patients age (29 - 50 years), with L4-L5 disc herniation, are divided randomly into group A- 30 patients underwent an open fenestration discectomy- and group B- 30 patients underwent fenestration microdiscectomy. All patients are assessed at 1 week, 3 months, 6 months, 12 months after surgery for Oswestry disability index and Visual analogue scale for back pain and leg pain and followed up for 4 years.ResultsIn both groups, all patients have minimal disability by Oswestry Disability Index after surgery. There were significant differences between means of post-operative Visual Analogue Scale for back pain between these two groups after 1 week (3.7 in group A versus 2.2 in group B) (t = 13.28, P = < 0.001*) and after 3 months (1.73 in group A versus 0.43 in group B) (t = 10.54, P = < 0.001*). There were no significant differences between two groups regarding post-operative VAS for leg pain, recurrence (5 patients in group A versus 4 patients in group B) and reoperation rate (2 patients in each group). There were significant differences between means of length of hospital stay (2.10 in group A versus 1.06 in group B) (P < 0.001), time of returning to daily activities (7.33 in group A versus 4.03 in group B) (P < 0.001) and cost of surgery (1996.66 in group A versus 3003.3 in group B) (P < 0.001).ConclusionUse of microscope in fenestration discectomy for treatment of symptomatic lumbar disc herniation can achieve the same goals of open fenestration regarding nerve root decompression and relief of leg pain with advantage of less back pain, less hospital staying and early return to daily activities with disadvantage of more cost with the use of microscope. With 4 years follow up, there was no significant deference in rate of recurrence and reoperation with the use of microscope but we found that type of surgery for recurrent cases may be less invasive if microscope was used in primary surgery.Trial registrationNCT, NCT04112485.

Project description:Study designSecondary analysis of data from a concurrent randomized trial and cohort study.ObjectiveThe aim of this study was to determine risks and predictors of recurrent pain following standard open discectomy for subacute/chronic symptomatic lumbar disc herniation (SLDH).Summary of background dataMost previous studies of recurrence after discectomy do not explicitly define pain resolution and recurrence, and do not account for variable durations of time at risk for recurrence.MethodsWe used survival analysis methods to examine predictors of leg pain recurrence. For individuals with initial resolution of leg pain, we defined recurrent leg pain as having leg pain, receiving lumbar epidural steroid injections, or undergoing lumbar surgery subsequent to initial leg pain resolution. We calculated cumulative risks of leg pain recurrence using Kaplan-Meier survival curves, and examined predictors of recurrence using Cox proportional hazards models. We used similar methods to examine LBP recurrence.ResultsOne- and three-year cumulative risks of leg pain recurrence were 20% and 45%, respectively. One- and three- year leg pain recurrence risks were substantially lower in participants with complete initial resolution of leg pain (17% and 41%, respectively) than in those without (27% and 54%, respectively). In multivariate analyses, complete leg pain resolution (adjusted hazard ratio [aHR] 0.69; 95% confidence interval [CI] 0.52-0.90), smoking (aHR 1.68 [95% CI 1.22-2.33]), and depression (aHR 1.74 [95% CI 1.18-2.56]) predicted leg pain recurrence. The 1- and 3-year risk of LBP recurrence was 29% and 65%, respectively. LBP recurrence risk at 3 years was substantially lower in participants with complete initial resolution of LBP than in those without, but not at 1 year.ConclusionRecurrence of leg pain and LBP is common after discectomy for SLDH. Cumulative risks of both leg pain and LBP recurrence were generally lower in participants achieving complete initial resolution of pain post-discectomy.Level of evidence2.

Project description:Incidental durotomy is an infrequent but well-recognized complication during lumbar disc surgery. The effect of a durotomy on long-term outcomes is, however, controversial. The authors sought to examine whether the occurrence of durotomy during surgery impacts long-term clinical outcome.Spine Patient Outcomes Research Trial (SPORT) participants who had a confirmed diagnosis of intervertebral disc herniation and were undergoing standard first-time open discectomy were followed up at 6 weeks and at 3, 6, and 12 months after surgery and annually thereafter at 13 spine clinics in 11 US states. Patient data from this prospectively gathered database were reviewed. As of May 2009, the mean (± SD) duration of follow-up among all of the intervertebral disc herniation patients whose data were analyzed was 41.5 ± 14.5 months (41.4 months in those with no durotomy vs 40.2 months in those with durotomy, p < 0.68). The median duration of follow-up among all of these patients was 47 months (range 1-95 months).A total of 799 patients underwent first-time lumbar discectomy. There was an incidental durotomy in 25 (3.1%) of these cases. There were no significant differences between the durotomy and no-durotomy groups with respect to age, sex, race, body mass index, herniation level or type, or the prevalence of smoking, diabetes, or hypertension. When outcome differences between the groups were analyzed, the durotomy group was found to have significantly increased operative duration, operative blood loss, and length of inpatient stay. However, there were no significant differences in incidence rates for nerve root injury, postoperative mortality, additional surgeries, or SF-36 scores for Bodily Pain or Physical Function, or Oswestry Disability Index scores at 1, 2, 3, or 4 years.Incidental durotomy during first-time lumbar discectomy does not appear to impact long-term outcome in affected patients.

Project description:Symptomatic lumbar disc herniation (LDH) is widely treated using percutaneous endoscopic lumbar discectomy (PELD). In the present PELD surgery, performing decompression under endoscope still takes a long time to explore the rupture site of annulus fibrosus, resulting in prolonged operation time and over-invasion of the undegenerated annulus fibrosus. A wide range of intraoperative exploration also induces an iatrogenic injury of the normal annulus fibrosus, even aggravating intervertebral disc degeneration, which may lead to early postoperative recurrence in severe case. Hence, it is important to seek a precise decompression in PELD surgery. Under this kind of realization, more spinal surgeons possibly choose a disc staining before performing decompression. However, the classical disc staining technique still has its shortcomings. First of all, an appropriate dose of staining cannot be accurately mastered, even induces unqualified staining effect. Second, the duration of surgery and the times of fluoroscopy will be increased. Finally, what surgeons see under the endoscope is the staining result but not the staining process. Hence, this is accomplished more effectively by designing procedures that perform fully visible disc staining under spinal endoscope. There is no specific research to discuss the technique note of endoscopic staining in PELD surgery. We have come up with a new original technology of endoscopic staining with methylene blue injection in PELD for treatment of LDH.

Project description:BackgroundOpen discectomy (OD) and microdiscectomy (MD) are routine procedures for the treatment of lumbar disc herniation. Minimally invasive surgery (MIS), such as micro-endoscopic discectomy (MED) and full endoscopic discectomy (FED), offers potential advantages (less pain, less bleeding, shorter hospitalisation and earlier return to work), but their complications have not yet been fully evaluated. The aim of this paper was to identify the frequency of these complications with a focus on MIS in comparison to OD/MD.MethodsThe authors conducted a Medline database search for randomised controlled and prospective cohort studies reporting complications associated with MIS and MD/OD from 1997 to February 2020. Included studies were assessed for bias using the Newcastle-Ottawa Quality assessment form. Mean complication rates for each technique were calculated by dividing the total number of each complication by the total number of patients included in the studies which reported that specific complication.ResultsOf the 1,095 articles retrieved from Medline, 35 met the inclusion criteria. OD, MD, MED and FED were associated with: recurrent lumbar disc hernias in 4.1%, 5.1%, 3.9% and 3.5% respectively; re-operations in 5.2%, 7.5%, 4.9% and 4% respectively; wound complications in 3.5%, 3.5%, 1.2% and 2% respectively; durotomy in 6.6%, 2.3%, 4.4% and 1.1% respectively; neurological complications in 1.8%, 2.8%, 4.5% and 4.9% respectively. Nerve root injury was reported in 0.3% for MD, 0.8% for MED and 1.2% for FED.DiscussionThis up-to-date systematic review of complications after various techniques of lumbar discectomy (including a large pool of patients who had MIS) confirms previous findings of low and comparable rates. However variable levels of bias were reported amongst included studies, which reported complications with varying levels of clinical detail.

Project description:BackgroundTransforaminal endoscopic lumbar discectomy (TELD) has well-recognized advantages and disadvantages in the literature. Some of the mentioned disadvantages are insufficient discectomy, higher recurrence rate and long learning curve (LC). The objective of this study is to describe the LC and analyze the survival rate of patients operated through TELD.MethodsRetrospective study of 41 cases operated through TELD by the same surgeon from June 2013 to January 2020, with a minimum follow-up of 6 months. Demographic data and information on operative time (OT), complications, hospital stay, hernia recurrence and reoperations were collected. LC of the TELD was analyzed using a cumulative sum (CUSUM) test for parameter stability for linear regression coefficients, using the CUSUM from recursive residuals.ResultsThirty-nine patients, 24 men (61.54%) and 15 women (38.46%), were included in the present cohort, and a total of 41 TELD were performed. The average OT was 96 minutes (SD =30) and the CUSUM of the recursive residuals shows learning of the TELD in the case 20. The mean OT in the first 20 cases was 114 minutes (SD =30) versus 80 minutes (SD =17) in the last 21 cases (P=0.0001). The rates of recurrent Dh were 17%, and 12% need reoperation.ConclusionsWe consider that the LC of TELD requires operating 20 cases to perform the procedure with a significant reduction in OT, with minimal rates of reoperation and complications.
