Abstract
PURPOSE Introducing a suture repair technology, endoscopic double line suture repair technique, for iatrogenic dural injury during Percutaneous Endoscopic Lumbar Discectomy (PELD) surgery. METHODS A patient with dural injury and cauda equina herniation during PELD surgery was treated with endoscopic double line suture repair technique. RESULTS A patient with dural injury and cauda equina nerve herniation during PELD surgery was successfully treated using double-line suture technique. After the repair, no obvious cerebrospinal fluid leakage and cauda equina nerve re-herniation was seen. During the postoperative observation period, the wound healed well and there were no complications related to cerebrospinal leakage. During the follow-up period (1 year), the patient reported significant symptom relief and no complications. CONCLUSION This novel dural repair technology is safe and effective and can be used to treat dural injuries during PELD surgery.

[PMID: 37625633 DOI: 10.1016/j.wneu.2023.08.075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 08/16/2023] [Indexed: 08/27/2023]
Abstract
BACKGROUND Cerebrospinal fluid (CSF) leakage is 1 of the common complications of spine surgery and is largely caused by intraoperative or postoperative dural tears. Associations of different factors with postoperative CSF leakage have not been consistent. In this study we aimed to identify demographic, disease-related, and surgical risk factors for CSF leakage after extradural spine surgery in a systematic review and meta-anlysis. METHODS The PubMed, EMBASE, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, Chinese Wanfang data, Chinese Weipu Database, and SinoMed databases were searched from inception until October 24, 2022. Fixed-effects or random-effects models were used to calculate odds ratios and 95% confidence intervals. The quality of observational studies was evaluated using the Newcastle-Ottawa scale instrument. RESULTS A total of 15 observational studies with 1,719,923 participants were included in this systematic review. All studies had a Newcastle-Ottawa scale score greater than or equal to 6. Age older than 70 years, smoking, ossification of the posterior longitudinal ligament, adhesion of spinal dura, spinal canal stenosis, cervical fracture, spondylolisthesis, revision surgery, and multiple surgical segments were all related to CSF leakage in the pooled analysis. Obesity and disease duration>1 year were not associated with the leakage of CSF. CONCLUSIONS This study will provide a reference for the identification of patients at high risk of developing CSF leakage, which suggests clinicians to strengthen the observation of drainage fluid in high-risk groups.

Abstract
Dural defects are common in spinal and cranial neurosurgery. A series of complications, such as cerebrospinal fluid leakage, occur after rupture of the dura. Therefore, treatment strategies are necessary to reduce or avoid complications. This review comprehensively summarizes the common causes, risk factors, clinical complications, and repair methods of dural defects. The latest research progress on dural repair methods and materials is summarized, including direct sutures, grafts, biomaterials, non-biomaterial materials, and composites formed by different materials. The characteristics and efficacy of these dural substitutes are reviewed, and these materials and methods are systematically evaluated. Finally, the best methods for dural repair and the challenges and future prospects of new dural repair materials are discussed.

Abstract
BACKGROUND The late presentation of dural tears (LPDT) has a low incidence rate and hidden symptoms and is easily ignored in clinical practice. If the disease is not treated in time, a series of complications may occur, including low intracranial pressure headache, infection, pseudodural cyst formation, and sinus formation. Here, we describe two cases of LPDT.
CASE SUMMARY Two patients had sudden fever 1 wk after lumbar surgery. Physical examination showed obvious tenderness in the operation area. The patients were confirmed as having LPDT by lumbar magnetic resonance imaging and surgical exploration. One case was caused by continuous negative pressure suction and malnutrition, and the other was caused by decreased dural ductility and low postoperative nutritional status. The first symptom of both patients was fever, with occasional headache. Both patients underwent secondary surgery to treat the LPDT. Dural defects were observed and dural sealants were used to seal the dural defects, then drainage tubes were retained for drainage. After the operation, the patients were treated with antibiotics and the patients’ surgical incisions healed well, without fever or incision tenderness. Both recovered and were discharged 1 wk after the operation.
CONCLUSION LPDT is a rare complication of spinal surgery or neurosurgery that has hidden symptoms and can easily be overlooked. Since it may cause a series of complications, LPDT needs to be actively addressed in clinical practice.

Incidental Durotomy After Posterior Lumbar Decompression Surgery Associated With Increased Risk for Venous Thromboembolism. J Am Acad Orthop Surg 2023; 31:e445-e450. [PMID: 36727948 DOI: 10.5435/jaaos-d-22-00917] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Accepted: 12/12/2022] [Indexed: 02/03/2023] Open
Abstract
INTRODUCTION Incidental durotomies can occur during posterior lumbar decompression surgery. Not only can this slow patient recovery but many surgeons recommend a period of bed rest in these situations, which can further slow mobilization. This immobility might be associated with increased risk of venous thromboembolism (VTE) after spinal surgery. This study aims to determine whether incidental durotomies are associated with increased risk of VTE in patients undergoing lumbar decompression surgery. METHODS Adult patients undergoing laminectomy or laminotomy (excluding any with concomitant fusion procedures) for degenerative etiologies and with a minimum of 90-day follow-up were identified from the MSpine Pearldiver dataset. Incidental durotomies were identified based on hospital administrative coding, and patient demographics, comorbidities, and the occurrence and timing of VTE (deep vein thrombosis [DVT] and/or pulmonary embolism) were defined. Univariate and multivariate analyses were performed. RESULTS Of 156,488 lumbar decompression patients included in the study, incidental durotomies was noted for 2,036 (1.3%). Markedly more VTEs were observed in the first five days in the incidental durotomies group (P < 0.001) but not incrementally any day after (P > 0.05). On univariate analyses, a significant increased risk of VTE, DVT, and PE was observed (P < 0.001 for each). On multivariate analyses controlling for age, sex, and comorbidities, odds were significantly increased for VTE (Odds ratios = 1.75, P < 0.001) and DVT (OR = 1.70, P < 0.001) but not independently significant for pulmonary embolism. DISCUSSION Patients who have incidental durotomies during lumbar laminectomy or laminotomy surgery were found to have increased odds of VTE, primarily in the first five days. Although not all factors associated with this could be directly determined, slower mobilization would seem to be a likely contributing factor. Increasing mobilization and/or adjusting chemoprophylaxis in this group would seem appropriately considered.

Abstract
Objective To review the research on the reasons of unplanned reoperation (URP) for degenerative lumbar spine diseases, and to provide new ideas for improving the quality of surgery for degenerative lumbar spine diseases. Methods The literature about the URP of degenerative lumbar spine diseases at home and abroad in recent years was reviewed and analyzed. Results At present, the reasons for URP include surgical site infection (SSI), hematoma formation, cerebrospinal fluid leakage (CSFL), poor results of surgery, and implant complications. SSI and hematoma formation are the most common causes of URP, which happen in a short time after surgery; CSFL also occurs shortly after surgery but is relatively rare. Poor surgical results and implant complications occurred for a long time after surgery. Factors such as primary disease and surgical procedures have an important impact on the incidence of URP. Conclusion The main reasons for URP are different in various periods after lumbar spine surgery. Interventions should be given to patients with high-risk URP, which thus can reduce the incidence of URP and improve the surgery quality and patients' satisfaction.

Spine J 2021; 21:2010-2018. [PMID: 34144204 DOI: 10.1016/j.spinee.2021.06.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Revised: 05/18/2021] [Accepted: 06/11/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Incidental durotomy during elective spine surgery is relatively common. While usually benign and self-limited, it can be associated with morbidity, increased cost, and medicolegal ramifications. Dural repair typically involves performing a primary closure using a suture or dural staple; repairs are then frequently augmented with a sealant, patch, or fat/fascial graft. Although primary repair of an incidental durotomy is standard practice, the ideal secondary sealant or augment choice remains unclear. A wide variety of commercially available dural sealant options exist, and while none have demonstrated consistent superiority, all are associated with single-use costs in the hundreds to thousands of dollars and have concerns regarding swelling, local inflammation, or short-lived dural adherence. PURPOSE The goal of this study is to compare the results of dural repair augmentation using an open intraoperative epidural blood patch to a hydrogel technique. STUDY DESIGN/SETTING Retrospective comparative cohort study at an academic referral center PATIENT SAMPLE: Adult patients undergoing lumbar spine surgery from March 2017 to January 2021 who sustained an incidental durotomy. Patients undergoing surgery for infection were excluded. OUTCOME MEASURES The primary outcome was failure of the repair as determined by a return to the operating room for re-exploration of a persistent cerebrospinal fluid (CSF) leak within 30 days of the index procedure. A secondary outcome was the incidence of a postoperative positional headache, and if present, the method used to obtain resolution. The primary predictor was use of a suture and hydrogel technique ("hydrogel" group), or the use of an epidural blood patch ("EBP" group). METHODS The method for applying an open epidural blood patch is presented in detail and involves primarily repairing the durotomy followed by allowing whole blood to pool and clot in the operative field until the durotomy is completely covered. This was compared with a group of patients undergoing secondary augmentation with commercially available hydrogel. In both groups, mechanical resistance to CSF leakage was confirmed with direct visualization and a Valsalva maneuver, respectively. Patients were instructed to remain flat until the morning after surgery. Chart review was used for data abstraction on preoperative, demographic, perioperative, and postoperative clinical factors. To compare between the hydrogel and EBP group, Wilcoxon rank-sum testing was used to test for non-parametric comparisons of means, and chi-square testing between binomial data. RESULTS Of 732 patients during the study period, forty-eight patients met study criteria. Twenty-five patients were in the hydrogel group and 23 in the EBP group. Mean age was 69.3 years (standard error 1.3 years). Patients were predominantly female (n = 31, 64.6%) with a mean BMI of 29.5 (SE 0.8), with no significant baseline differences between the hydrogel and EBP groups. Two patients in the hydrogel group (8.0%) and two in the EBP group (8.7%) had mild positional headaches postoperatively that resolved without intervention within 24 hours. One (4.3%) patient in the EBP group had positional headaches following an initial headache-free period; this patient was returned to the operating room and no evidence of a persistent CSF leak was found despite meticulous exploration. CONCLUSIONS An open, intraoperatively placed epidural blood patch may be an efficacious and cost-effective way to manage an incidental durotomy. This method merits further study as an allergy-free, no swell, cost-neutral method of dural repair augmentation.

Dural Tear Does not Increase the Rate of Venous Thromboembolic Disease in Patients Undergoing Elective Lumbar Decompression with Instrumented Fusion. World Neurosurg 2021; 154:e649-e655. [PMID: 34332152 DOI: 10.1016/j.wneu.2021.07.107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Revised: 07/21/2021] [Accepted: 07/22/2021] [Indexed: 11/22/2022]
Abstract
OBJECTIVE Evaluate if dural tears (DTs) are an indirect risk factor for venous thromboembolic disease through increased recumbency in patients undergoing elective lumbar decompression and instrumented fusion. METHODS This was a retrospective cohort study of consecutive patients undergoing elective lumbar decompression and instrumented fusion at a single institution between 2016 and 2019. Patients were divided into cohorts: those who sustained a dural tear and those who did not. The cohorts were compared using Student's t-test or Wilcoxon Rank Sum for continuous variables and Fisher exact or chi-squared test for nominal variables. RESULTS Six-hundred and eleven patients met inclusion criteria, among which 144 patients (23.6%) sustained a DT. The DT cohort tended to be older (63.6 vs. 60.6 years, P = 0.0052) and have more comorbidities (Charlson Comorbidity Index 2.75 vs. 2.35, P = 0.0056). There was no significant difference in the rate of symptomatic deep vein thrombosis (2.1% vs. 2.6%, P = 1.0) or pulmonary embolus (1.4% vs. 1.50%, P = 1.0). Intraoperatively, DT was associated with increased blood loss (754 mL vs. 512 mL, P < 0.0001), operative time (224 vs. 195 minutes, P < 0.0001), and rate of transfusion (19.4% vs. 9.4%, P = 0.0018). Postoperatively, DT was associated with increased time to ambulation (2.6 vs. 1.4 days, P < 0.0001), length of stay (5.8 vs. 4.0 days, P < 0.0001), and rate of discharge to rehab (38.9 vs. 25.3%, P = 0.0021). CONCLUSIONS While DTs during elective lumbar decompression and instrumentation led to later ambulation and longer hospital stays, the increased recumbency did not significantly increase the rate of symptomatic venous thromboembolic disease.

Abstract
STUDY DESIGN Technical note. OBJECTIVES Management of postoperative cerebrospinal fluid (CSF) leaks is a challenge. Reexploration increases the morbidity risks. The main objective was to evaluate the outcomes of noninvasive zipper-like system (Zip surgical skin closure system, ZipLine Medical, Inc, Campbell, CA, USA) as a bailout technique for postoperative CSF leaks. METHODS Retrospective case series. Consecutive patients with postoperative CSF leaks that occurred secondary to spinal surgeries performed between January 2017 and September 2018 were part of the study. All these patients were managed conservatively by reinforcement with zipper ratcheting straps over the sutured surgical wound. Successful clinical outcomes included cessation of CSF leaks and adequate wound healing in the postoperative period and at follow-up. RESULTS Ten patients underwent the application of zipper ratcheting straps. The mean follow-up was 6 months (range 6 months to 1 year). In 7 cases, the dural tears were recognized postoperatively and in 3 cases, the tears were noted intraoperatively and repaired and reinforced with fibrin sealants. None of the patients developed wound soakage or subsequent CSF leak from the wound after the application of zipper ratcheting straps. CONCLUSIONS Zipper ratcheting straps as augmentation to sewing of the wound seem to be a good alternative and bailout in treating patients with postoperative CSF leaks. The ease of its application, the ability in minimizing the complications associated with CSF leaks, and negating the need of surgical reexploration makes it a worthy option.

Abstract
Adult spinal deformity (ASD) is a challenging problem for spine surgeons given the high risk of complications, both medical and surgical.
Surgeons should have a high index of suspicion for medical complications, including cardiac, pulmonary, thromboembolic, genitourinary and gastrointestinal, renal, cognitive and psychiatric, and skin conditions, in the perioperative period and have a low threshold for involving specialists.
Surgical complications, including neurologic injuries, vascular injuries, proximal junctional kyphosis, durotomy, and pseudarthrosis and rod fracture, can be devastating for the patient and costly to the health-care system. Mortality rates have been reported to be between 1.0% and 3.5% following ASD surgery. With the increasing rate of ASD surgery, surgeons should properly counsel patients about these risks and have a high index of suspicion for complications in the perioperative period.

Abstract
STUDY DESIGN Retrospective database analysis. OBJECTIVE The aim of this study was to match risk factors for complications in patients who did and did not sustain a dural tear while undergoing posterior lumbar spine surgery and compare local and systemic complications. SUMMARY OF BACKGROUND DATA Current data do not adequately define whether the event of sustaining an isolated dural tear increases the risk for postoperative complications while controlling for other confounding risk factors. METHODS The PearlDiver Database was queried for patients who underwent posterior lumbar spine decompression and/or fusion for degenerative pathology. Patients with and without dural tears were 1:2 matched based on demographic variables and comorbidities. Complications, cost, length of stay (LOS), and readmission rates were analyzed. RESULTS The 1:2 matched cohort included 9038 patients with a dural tear and 17,340 patients without a dural tear. All complications assessed were significantly higher in the dural tear group (P < 0.03). Venothromboembolic (VTE) events occurred in 1.3% of patients with a dural tear and 0.9% of patients without a dural tear (odds ratio [OR] 1.46, P < 0.0001). Meningitis occurred in 25 patients (0.3%) with a dural tear and eight patients (<0.1%) without a dural tear (OR 6.0, P < 0.0001). Patients with a dural tear had 120% higher medical costs, 200% greater LOS, and were two times more likely to be readmitted (P < 0.0001). CONCLUSION Sustaining a dural tear while undergoing posterior lumbar spinal decompression and/or fusion for degenerative pathology significantly increased the risk of complications and increased length of stay, risk of readmission, and overall 90-day hospital cost. Dural tears specifically increased the risk of a VTE complication by 1.46 times and meningitis by six times; these are important complications to have a high degree of suspicion for in the setting of durotomy, as they can lead to significant morbidity for the patient.

Abstract
BACKGROUND Symptoms and evidence of cerebrospinal fluid (CSF) leak after an uneventful intraoperative and immediate postoperative course are a rare entity in spine surgery. The literature is sparse on the description of such late presenting dural tears (LPDTs). They may need further admissions, wound management, and additional surgical procedures that add to the morbidity of the patient. METHODS A retrospective review of spine surgeries done at our institute for degenerative spinal conditions between January 2017 and January 2018 was conducted. A mini meta-analysis was performed on studies comparing conservative and surgical management of LPDTs. RESULTS Among 1929 patients, 6 cases (5 lumbar and 1 cervical) had an LPDT. Five of them had a CSF fistula and 1 patient had a pseudomeningocele. Two patients with CSF fistula were complicated by superficial surgical site infection (SSI). There was additional evidence of pneumocephalus and pneumorachis in 1 case. The SSI was managed by bedside debridement, regular dressing, and culture-sensitive antibiotics. CSF fistulas were managed by deep suturing, and pseudomeningocele was managed by excision of the sac and plication of the neck. All the patients had a good to an excellent outcome at the end of a 1-year follow-up. CONCLUSIONS One should be aware of the possibility of LPDTs. A combination of history, clinical examination, and imaging may aid in the diagnosis. It can be associated with complications like CSF fistula, pseudomeningocele, SSI, pneumocephalus, or pneumorachis. Conservative trial can have good to excellent outcomes in the management of such cases though there is insufficient evidence to establish it.

Abstract
Aims The aim of this study was to explore risk factors for complications associated with dural tear (DT), including the types of DT, and the intra- and postoperative management of DT. Patients and Methods Between 2012 and 2017, 12 171 patients with degenerative lumbar diseases underwent primary lumbar spine surgery. We investigated five categories of potential predictors: patient factors (sex, age, body mass index, and primary disease), surgical factors (surgical procedures, operative time, and estimated blood loss), types of DT (inaccessible for suturing/clipping and the presence of cauda equina/nerve root herniation), repair techniques (suturing, clipping, fibrin glue, polyethylene glycol (PEG) hydrogel, and polyglycolic acid sheet), and postoperative management (drainage duration). Postoperative complications were evaluated in terms of dural leak, prolonged bed rest, headache, nausea/vomiting, delayed wound healing, postoperative neurological deficit, surgical site infection (SSI), and reoperation for DT. We performed multivariable regression analyses to evaluate the predictors of postoperative complications associated with DT. Results In total, 429/12 171 patients (3.5%) had a DT. Multivariable analysis revealed that PEG hydrogel significantly reduced the incidence of dural leak and prolonged bed rest, and that patients treated with sealants (fibrin glue and PEG hydrogel) significantly less frequently suffered from headache. A longer drainage duration significantly increased the incidence of headache, nausea/vomiting, and delayed wound healing. Headache and nausea/vomiting were significantly more prevalent in younger female patients. Postoperative neurological deficit and reoperation for DT significantly depended on the presence of cauda equina/nerve root herniation. A longer operative time was the sole independent risk factor for SSI and was also a risk factor for dural leak, prolonged bed rest, and nausea/vomiting. Conclusion Sealants, particularly PEG hydrogel, may be useful in reducing symptoms related to cerebrospinal fluid leakage, whereas prolonged drainage may be unnecessary. Younger female patients should be carefully treated when DT occurs. Cite this article: Bone Joint J 2019;101-B:1115–1121.

Reporting Methodology of Neurosurgical Studies Utilizing the American College of Surgeons-National Surgical Quality Improvement Program Database: A Systematic Review and Critical Appraisal. Neurosurgery 2019; 86:46-60.

Abstract
AbstractBACKGROUNDUse of large databases such as the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) has become increasingly common in neurosurgical research.OBJECTIVETo perform a critical appraisal and evaluation of the methodological reporting for studies in neurosurgical literature that utilize the ACS-NSQIP database.METHODSWe queried Ovid MEDLINE, EMBASE, and PubMed databases for all neurosurgical studies utilizing the ACS-NSQIP. We assessed each study according to number of criteria fulfilled with respect to Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement, REporting of studies Conducted using Observational Routinely-collected Health Data (RECORD) Statement, and Journal of American Medical Association–Surgical Section (JAMA-Surgery) Checklist. A separate analysis was conducted among papers published in core and noncore journals in neurosurgery according to Bradford's law.RESULTSA total of 117 studies were included. Median (interquartile range [IQR]) scores for number of fulfilled criteria for STROBE Statement, RECORD Statement, and JAMA-Surgery Checklist were 20 (IQR:19-21), 9 (IQR:8-9), and 6 (IQR:5-6), respectively. For STROBE Statement, RECORD Statement, and JAMA-Surgery Checklist, item 9 (potential sources of bias), item 13 (supplemental information), and item 9 (missing data/sensitivity analysis) had the highest number of studies with no fulfillment among all studies (56, 68, 50%), respectively. When comparing core journals vs noncore journals, no significant difference was found (STROBE, P = .94; RECORD, P = .24; JAMA-Surgery checklist, P = .60).CONCLUSIONWhile we observed an overall satisfactory reporting of methodology, most studies lacked mention of potential sources of bias, data cleaning methods, supplemental information, and external validity. Given the pervasive role of national databases and registries for research and health care policy, the surgical community needs to ensure the credibility and quality of such studies that ultimately aim to improve the value of surgical care delivery to patients.
