Methods: Patients with single-segment lumbar disc herniation who were treated in Dazhou Central Hospital between May 2014 and February 2017 were selected as the research subjects, the history data were reviewed and the operation methods were referred to divide them into FD group and MED group who received fenestration discectomy and microendoscopic discectomy respectively. The conduction velocity of common peroneal nerve and tibial nerve were detected before operation and 4 weeks after operation;serum levels of nerve and muscle injury-related molecules as well as inflammation and stress-related molecules were detected before operation and 3 days after operation. Results: MNCV levels of common peroneal nerve and tibial nerve 4 weeks after operation as well as serum CRP, TNF-α, MDA and AOPP contents 3 d after operation of both groups of patients were significantly higher than those before operation, and the MNCV levels of common peroneal nerve and tibial nerve of MED group 4 weeks after operation were significantly higher than those of FD group while serum CRP, TNF-α, MDA and AOPP contents of MED group 3 d after operation were not significantly different from those of FD group;serum NSE, S100B, Tau, pNF-H, CPK, Myo and LDH contents of FD patients 3 d after operation were significantly higher than those before operation while serum NSE, S100B, Tau, pNF-H, CPK, Myo and LDH contents of MED group were not significantly different from those before operation. Conclusion: Microendoscopic discectomy for lumbar disc herniation can relieve the nerve and muscle injury, and is equivalent to fenestration discectomy in activating the systemic stress and inflammatory response.展开更多

Kambin and Gellmann in 1973 in the United States and Hijikata in Japanin 1977 individually preformed posterolateral percutaneous nucleotomy for the resection of the nucleus pulposus and release of compressed exiting nerve root, which is now spreading through the world and many surgeons are developing their skill but it needs experience and patience for successful outcomes. Along with advanced instruments now the surgery can be performed only giving a small skin incision of 8 - 10 mm and is as effective as the conventional method of surgery and open microdiscectomy surgery for the treatment of symptomatic lumbar disc herniation. In this review, we are explaining the technique of minimally invasive Percutaneous Transforaminal Endoscopic Discectomy surgery along its advantages and complications which can be encountered while performing this technique.展开更多

Methods: From August 2017 to June 2019, 42 patients with low lumbar single segment lumbar disc herniation were treated with percutaneous transforaminal endoscopic discectomy surgery in our hospital. The operation time, incision size, bleeding volume and hospitalization time were recorded respectively. The patients were evaluated before operation, 1 month and 6 months after operation. Visual analogue scale (VAS) and assessment were used to evaluate the lumbocrural pain. The JOA score and the Oswestry disability index (ODI) were used to evaluate the lumbar function, and the modified macnab score was used to evaluate the clinical effect in the last follow-up. Results: All the 42 patients successfully completed the operation without any other operation. There were no severe complications such as dural injury and nerve root injury. The operation time was (76.98 ± 8.58) min, the incision size was (8.45 ± 1.2) mm, the bleeding volume was (20.14 ± 2.93) ml, and the hospitalization time was (4.55 ± 1.13) d. One month and six months after the operation, the visual analogue scale (VAS), the evaluation of lumbar function (Oswestry) and the disability index (ODI) were significantly improved compared with those before the operation (P Conclusion: The treatment of low lumbar but segmental lumbar disc herniation with percutaneous intervertebral foramen, with small incision, less bleeding and quick recovery, can improve the pain and dysfunction of patients.展开更多

Patients in PTED group received percutaneous transforaminal endoscope discectomy, while control group received open fenestration discectomy. Serum levels of pain substances SP, NPY, PGE2 and NGF, inflammatory mediators IFN-γ, TNF-α, IL-17 and MMP3 as well as stress response substances Cor, NE, OH-, O2- and MDA of two groups of patients were determined the same day after surgery and 3 days after surgery.Results: The same day after surgery and 3 d after surgery, serum SP, NPY, PGE2, NGF, IFN-γ, TNF-α, IL-17, MMP3, Cor, NE, OH-, O2- and MDA levels of PTED group were significantly lower than those of control group. Conclusion: Percutaneous transforaminal endoscope discectomy for lumbar intervertebral disc herniation causes less postoperative pain and inflammatory stress than open fenestration discectomy.展开更多

Methods Eighty-two cases of lumbar disc herniation, from February 1996 to May 1999, were retrospectively studied. All patients were treated with simple fenestrated discectomy. The average follow-up time was 8 years and 7 months （from 7 years tolO years and 3months）. There were 13, 38 and 31 cases at 13 - L4, L4 - L5 and L5 - S1 level, respectively. Results The average scales before operation were as following ： Japanes Orthopaedics Association （ JOA ） scale 6. 5 （ 5 - 9 ） , visual analysis scale （ VAS） of low back pain4.8 （0-8）. and VAS of sciatica 7.2 （4-10）. At the final follow-up, the above parameters were 13.2 （ 10 - 14 ）, 1.8 （0 - 10） and 1.2 （0 - 7）, respectively. The average increase ratio of JOA scale was 78. 8%. The average disc-vertebra height ratio （ Mochida method） was 80.2%. At the final follow-up, 7 cases reoccurred disc herniation. The final clinical satisfaction rate was 80% （ modified Macnab method ）. Conclusion With appropriate surgical indications, the successfid long-term outcomes could be expected with fenestrated discectomy. Discectomy improves sciatica to a greater extent than low back pain. The occurrence of low back pain is related to intervertebral disc height, segment stability, disc degeneration, and lumbar muscle disability.展开更多

When conservative treatments are ineffective, then it is treated by surgeries, more recently with minimal invasive percutaneous endoscopic lumbar surgery (PELS). One of the mostly accepted PELS by spinal surgeons is percutaneous transforaminal endoscopic lumbar discectomy, which can be performed for any age. The main aim of this review was to evaluate clinical outcome and safety based on the Oswestry Disable Index (ODI), Visual Analog Scale (VAS) and MacNab criteria and complications of PELS surgery and its advantages in clinical basis.展开更多

We evaluated the effectiveness and safety of lumbar MED at stages of spinal surgeons＇ learning curve. Methods Fifty patients receiving MED from June 2002 to February 2003 were divided into chronological groups of ten each： A-E. The control group F was ten MED patients treated later by the same medical team （September-October 2006）. All operations were performed by the same team of spinal surgeons with no MED experience before June 2002. We compared groups by operation time, blood loss, complications and need for open surgery after MED failure. Results Operation times by group were： A, （107±14） minutes; B, （85±13） minutes; C, （55±19） minutes; D, （52±12） minutes; E, （51±13） minutes; and F, （49±15） minutes. Blood loss were： A, （131±73） ml; B, （75±20） ml; C, （48±16） ml; D, （44±17） ml; E, （45±18） ml; and F, （45±16） ml. Both operation time and blood loss in groups C, D, E and F were smaller and more stable compared with groups A and B. Japanese Orthopedic Association assessment （JOA） score of each group in improvement rate immediately and one year after operation were as follows （in percentage）： A, （79.8±8.8）/（89.8±7.7）; B, （78.6±8.5）/（88.5±7.8）; C, （80.8±11.3）/（90.8±6.7）; D, （77.7±11.4）/（88.9±9.3）; E, （84.0±8.7）/（89.6±9.0）; and F, （77.8±11.6）/ （86.9±8.4）. Groups showed no statistical difference in improvement rates. Complications developed in three patients in group A, two in group B, and none in the other groups. Conclusions Spinal surgeons performing MED become proficient after 10-20 operations, when their skill becomes fairly sophisticated. Patients＇ improvement rate is the same regardless of surgeons＇ phase of learning curve.展开更多
文摘Objective: To study the difference of nerve conduction and injury degree in patients with lumbar disc herniation after microendoscopic discectomy and fenestration discectomy. Methods: Patients with single-segment lumbar disc herniation who were treated in Dazhou Central Hospital between May 2014 and February 2017 were selected as the research subjects, the history data were reviewed and the operation methods were referred to divide them into FD group and MED group who received fenestration discectomy and microendoscopic discectomy respectively. The conduction velocity of common peroneal nerve and tibial nerve were detected before operation and 4 weeks after operation;serum levels of nerve and muscle injury-related molecules as well as inflammation and stress-related molecules were detected before operation and 3 days after operation. Results: MNCV levels of common peroneal nerve and tibial nerve 4 weeks after operation as well as serum CRP, TNF-α, MDA and AOPP contents 3 d after operation of both groups of patients were significantly higher than those before operation, and the MNCV levels of common peroneal nerve and tibial nerve of MED group 4 weeks after operation were significantly higher than those of FD group while serum CRP, TNF-α, MDA and AOPP contents of MED group 3 d after operation were not significantly different from those of FD group;serum NSE, S100B, Tau, pNF-H, CPK, Myo and LDH contents of FD patients 3 d after operation were significantly higher than those before operation while serum NSE, S100B, Tau, pNF-H, CPK, Myo and LDH contents of MED group were not significantly different from those before operation. Conclusion: Microendoscopic discectomy for lumbar disc herniation can relieve the nerve and muscle injury, and is equivalent to fenestration discectomy in activating the systemic stress and inflammatory response.

文摘BACKGROUND The technique of percutaneous endoscopic lumbar discectomy(PELD)as a transforaminal approach has been used to treat highly migrated lower lumbar disc herniations.However,due to the different anatomic characteristics of the upper lumbar spine,conventional transforaminal PELD may fail to remove the highly migrated upper lumbar disc nucleus pulposus.Therefore,the purpose of this study was to describe a novel surgical technique,two-level PELD,for the treatment of highly migrated upper lumbar disc herniations and to report its related clinical outcomes.CASE SUMMARY A 60-year-old male presented with a complaint of pain at his lower back and right lower limb.The patient received 3 mo of conservative treatments but the symptoms were not alleviated.Physical examination revealed a positive femoral nerve stretch test and a negative straight leg raise test for the right leg,and preoperative visual analog scale(VAS)score for the lower back was 6 points and for the right leg was 8 points.Magnetic resonance imaging(MRI)demonstrated L2-L3 disc herniation on the right side and the herniated nucleus pulposus migrated to the upper margin of L2 vertebral body.According to physical examination and imaging findings,surgery was the primary consideration.Therefore,the patient underwent surgical treatment with two-level PELD.The pain symptom was relieved and the VAS score for back and thigh pain was one point postoperatively.The patient was asymptomatic and follow-up MRI scan 1 year after operation revealed no residual nucleus pulposus.CONCLUSION Two-level PELD as a transforaminal approach can be a safe and effective procedure for highly migrated upper lumbar disc herniation.
文摘Objective: To observe the clinical effect percutaneous transforaminal endoscopic discectomy (PTED) in the treatment of single lumbar disc herniation. Methods: From August 2017 to June 2019, 42 patients with low lumbar single segment lumbar disc herniation were treated with percutaneous transforaminal endoscopic discectomy surgery in our hospital. The operation time, incision size, bleeding volume and hospitalization time were recorded respectively. The patients were evaluated before operation, 1 month and 6 months after operation. Visual analogue scale (VAS) and assessment were used to evaluate the lumbocrural pain.

文摘BACKGROUND Percutaneous endoscopic lumbar discectomy(PELD)has become a mature and mainstream minimally invasive surgical technique for treating lumbar disc herniation(LDH).Repeated fluoroscopy,with more than 30 shots on average,is inevitable to ensure its accuracy and safety.However,exposure to X-rays may pose a threat to human health.We herein report a case of ultrasound(US)-assisted PELD in two levels of LDH to explore a new possibility that can reduce the radiation dose during puncture and cannulation in PELD.CASE SUMMARY A 38-year-old man with low back pain and left leg pain for more than 7 years came to our clinic,his symptoms had aggravated for 1 month,and he was diagnosed with L3-4 and L4-5 disc herniations.He received US-guided PELD with good results:His straight leg elevation increased from 40 to 90 degrees after PELD,and his visual analog scale(VAS)and Oswestry Disability Index scores both significantly decreased immediately and 6 mo after PELD.With the guidance of US,he received only two shots of fluoroscopy(fluoroscopic time:4.4 s;radiation dose:3.98 mGy).To our knowledge,this is the first case of US-guided puncture and cannulation of PELD for LDH at two levels.CONCLUSION US could be used to guide PELD and has the potential to largely reduce radiation than traditional X-ray guidance.
文摘Objective:To study the differences in pain and inflammatory stress after percutaneous transforaminal endoscope discectomy and open fenestration discectomy.Methods: Patients with lumbar intervertebral disc herniation who underwent surgical treatment in our hospital between January 2013 and January 2017 were selected and randomly divided into two groups: Percutaneous transforaminal endoscope discectomy (PTED) group and control group. Patients in PTED group received percutaneous transforaminal endoscope discectomy, while control group received open fenestration discectomy. Serum levels of pain substances SP, NPY, PGE2 and NGF, inflammatory mediators IFN-γ, TNF-α, IL-17 and MMP3 as well as stress response substances Cor, NE, OH-, O2- and MDA of two groups of patients were determined the same day after surgery and 3 days after surgery.Results: The same day after surgery and 3 d after surgery, serum SP, NPY, PGE2, NGF, IFN-γ, TNF-α, IL-17, MMP3, Cor, NE, OH-, O2- and MDA levels of PTED group were significantly lower than those of control group. Conclusion: Percutaneous transforaminal endoscope discectomy for lumbar intervertebral disc herniation causes less postoperative pain and inflammatory stress than open fenestration discectomy.
文摘Objective To evaluate the long-term outcomes of fenestrated discectomy for lumbar disc herniation and analyze the correlative influence factors. Methods Eighty-two cases of lumbar disc herniation, from February 1996 to May 1999, were retrospectively studied. All patients were treated with simple fenestrated discectomy. The average follow-up time was 8 years and 7 months （from 7 years tolO years and 3months）. There were 13, 38 and 31 cases at 13 - L4, L4 - L5 and L5 - S1 level, respectively. Results The average scales before operation were as following ： Japanes Orthopaedics Association （ JOA ） scale 6. 5 （ 5 - 9 ） , visual analysis scale （ VAS） of low back pain4.8 （0-8）. and VAS of sciatica 7.2 （4-10）. At the final follow-up, the above parameters were 13.2 （ 10 - 14 ）, 1.8 （0 - 10） and 1.2 （0 - 7）, respectively. The average increase ratio of JOA scale was 78. 8%. The average disc-vertebra height ratio （ Mochida method） was 80.2%. At the final follow-up, 7 cases reoccurred disc herniation. The final clinical satisfaction rate was 80% （ modified Macnab method ）. Conclusion With appropriate surgical indications, the successfid long-term outcomes could be expected with fenestrated discectomy. Discectomy improves sciatica to a greater extent than low back pain. The occurrence of low back pain is related to intervertebral disc height, segment stability, disc degeneration, and lumbar muscle disability.

文摘Objective:To investigate the early efficacy of two approaches for lumbar disc herniation under spinal endoscopy.Methods:45 cases of lumbar disc herniation were divided into interlaminar approach(27 cases)and intervertebral foramen approach(18 cases)according to different surgical approaches.Postoperative pain visual analogue scale(VAS)was used.Japanese Orthopaedic Association(JOA)lumbar spine score(JOA)and modified Macnab criteria were used to evaluate the postoperative outcome.Results:(1)VAS score.There is no interaction effect between the access mode and the time factor(F=0.620,P=0.603).There were statistically significant differences in pain VAS scores between preoperative and postoperative time points,that is,there was a time effect(F=2157.488,P=0.000).The overall VAS scores of the two groups were compared,and the difference was not statistically significant,that is,there was no grouping effect(F=2.610,P=0.114).The VAS score of pain in both groups decreased with time,and the differences between the two groups were not statistically significant before surgery,at discharge,1 month after surgery and 3 months after surgery(t=0.067,P=0.947;t=1.415,P=0.164;t=0.564,P=0.575;t=0.442,P=0.660);JOA score.There is no interaction effect between the access mode and the time factor(F=1.296,P=0.280).The difference of JOA score between preoperative and postoperative time points was statistically significant,that is,there was a time effect(F=1464.830,P=0.000).JOA scores of the two groups showed an increasing trend with time,and the differences between the two groups were not statistically significant before surgery,at discharge,1 month after surgery and 3 months after surgery(t=0.067,P=0.947;t=1.415,P=0.164;t=0.564,P=0.575;t=0.442,P=0.660);(2)The improved Macnab standard was used to evaluate the excellent and good rate at 3 months after surgery.In the interlaminar group,12 cases were excellent,13 cases were good and 2 cases were fair.The excellent and good rate was 92.6%.In the intervertebral foramen group,7 cases were excellent,10 cases were good and 1 case was fair.The excellent and good rate was 94.4%.The overall excellent and good rate of the two groups was 93.3%.Conclusion:Both approaches can achieve satisfactory efficacy in the treatment of lumbar intervertebral disc herniation,which is worthy of clinical application.However,for beginners,l5-s1 lumbar disc herniation is more suitable for intervertebral disc approach,so as to achieve satisfactory efficacy.
文摘Background Microendoscopic discectomy （MED） is a minimally invasive operation that allows rapid recovery from surgery for lumbar disc herniation, but has replaced traditional open surgery in few hospitals because most surgeons avoid its long learning curve. We evaluated the effectiveness and safety of lumbar MED at stages of spinal surgeons＇ learning curve. Methods Fifty patients receiving MED from June 2002 to February 2003 were divided into chronological groups of ten each： A-E. The control group F was ten MED patients treated later by the same medical team （September-October 2006）. All operations were performed by the same team of spinal surgeons with no MED experience before June 2002. We compared groups by operation time, blood loss, complications and need for open surgery after MED failure. Results Operation times by group were： A, （107±14） minutes; B, （85±13） minutes; C, （55±19） minutes; D, （52±12） minutes; E, （51±13） minutes; and F, （49±15） minutes. Blood loss were： A, （131±73） ml; B, （75±20） ml; C, （48±16） ml; D, （44±17） ml; E, （45±18） ml; and F, （45±16） ml. Both operation time and blood loss in groups C, D, E and F were smaller and more stable compared with groups A and B. Japanese Orthopedic Association assessment （JOA） score of each group in improvement rate immediately and one year after operation were as follows （in percentage）： A, （79.8±8.8）/（89.8±7.7）; B, （78.6±8.5）/（88.5±7.8）; C, （80.8±11.3）/（90.8±6.7）; D, （77.7±11.4）/（88.9±9.3）; E, （84.0±8.7）/（89.6±9.0）; and F, （77.8±11.6）/ （86.9±8.4）. Groups showed no statistical difference in improvement rates. Complications developed in three patients in group A, two in group B, and none in the other groups. Conclusions Spinal surgeons performing MED become proficient after 10-20 operations, when their skill becomes fairly sophisticated. Patients＇ improvement rate is the same regardless of surgeons＇ phase of learning curve.
