Technique of Percutaneous Transforaminal Endoscopic Discectomy for the Treatment of Lumbar Disc Herniation

Percutaneous Transforaminal Endoscopic Discectomy is a minimally invasive surgery with little pain, less blood loss, less hospital stay and the surgery can be done in local anesthesia, which was started during late 20th century. 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.

Comparison of microendoscopic discectomy and open discectomy for single-segment lumbar disc herniation

BACKGROUND Lumbar disc herniation is a common disease.Endoscopic treatment may have more advantages than traditional surgery.AIM To compare the clinical efficacy and safety of microendoscopic discectomy(MED)and open discectomy with lamina nucleus enucleation in the treatment of singlesegment lumbar intervertebral disc herniation.METHODS Ninety-six patients who were operated at our hospital were selected for this study.Patients with single-segment lumbar disc herniation were admitted to the hospital from March 2018 to March 2019 and were randomly divided into the observation group and the control group with 48 cases in each group.The former group underwent lumbar discectomy and the latter underwent laparotomy and nucleus pulpectomy.Surgical effects were compared between the two groups.RESULTS In terms of surgical indicators,the observation group had a longer operation time,shorter postoperative bedtime and hospital stay,less intraoperative blood loss,and smaller incision length than the control group(P<0.05).The excellent recovery rate did not differ significantly between the observation group(93.75%)and the control group(91.67%).Visual analogue scale pain scores were significantly lower in the observation group than in the control group at 1 d,3 d,1 mo,and 6 mo after surgery(P<0.05).The incidence of complications was significantly lower in the observation group than in the control group(6.25%vs 22.92%,P<0.05).CONCLUSION Both MED and open discectomy can effectively improve single-segment lumbar disc herniation,but MED is associated with less trauma,less bleeding,and a lower incidence of complications.

Two-level percutaneous endoscopic lumbar discectomy for highly migrated upper lumbar disc herniation: A case report

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.

The Clinical Effect of Percutaneous Transforaminal Endoscopic Discectomy in the Treatment of Low Lumbar Single Segment Disc Herniation

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. 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.

Microendoscopic discectomy for treatment of lumbar disc herniation

A lumbar microendoscopic discectomy(MED)is a minimally invasive surgical technique performed through a tubular device which is designed for the pain relieve caused by herniated discs pressing the nerve roots.In 1997,a new minimally invasive surgical approach for the management of symptomatic lumbar disc herniation,MED was introduced.This technique uses a tubular retractor system and a microendoscope for visualization rather than the operating microscope.However,recent literature suggests that MED is an effective microendoscopic system which has a fine long-term outcome in treating lumbar disc herniation.This article describes the operative techniques and outcomes reported in the literature for MED.

Comparison of nerve conduction and injury degree in patients with lumbar disc herniation after microendoscopic discectomy and fenestration discectomy

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.

Clinical Outcome of Percutaneous Endoscopic Lumbar Surgery (PELS) in Treatment of Lumbar Disc Herniation

Lumbar disc herniation is a spinal problem seen in both young and old people causing pain in the back with pain and numbness in lower extremity leading to disability limiting daily activities. 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.

Early efficacy of endoscopic translaminar and intervertebral foraminal approaches in the treatment of lumbar disc herniation

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.

Ultrasound guidance for transforaminal percutaneous endoscopic lumbar discectomy may prevent radiation exposure: A case report

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.

LONG-TERM OUTCOMES OF FENESTRATED DISCECTOMY FOR LUMBAR DISC

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.
