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

Diagnosis of both Lumbar Disc Herniation and Lumbar Spine Stenosis depends on clinical findings as well as radiological investigations. Treatment of choice of these conditions is on the basis of the patient conditions. Surgical treatment is the option only when the conservative treatment does not improve the patient’s clinical condition. Advancement and improvement of the technology have resulted in the traditional open surgical treatment into minimal invasive surgery. Intervention of the different surgical instruments with expert spinal surgeons had made percutaneous endoscopic lumbar Spine surgery as one of the preferred choices of surgery for treating Lumbar Disc Herniation and Lumbar Spine Stenosis. The concept of percutaneous endoscopic surgery for lumbar region is to provide surgical options without producing iatrogenic morbidity associated with the open surgical procedures. Conventionally, there are different approaches/techniques for Percutaneous Endoscopic Lumbar Spine Surgery, but in this review we are mainly focusing on the Transforaminal Technique. Regarding the Lumbar Disc Herniation treatment with transforaminal approach, a number of articles have been published due to which we mainly focused on those articles which were published after 2009 onwards. While fewer articles related to Lumbar Spine Stenosis treatment with Transforaminal approach were found, we tried to brief out all those articles. On the basis of comparative study of different surgeries done for Lumbar Disc Herniation and Lumbar Spine Stenosis, Percutaneous Transforaminal endoscopic Lumbar Surgery provides a substantial benefit. Transforaminal approach for treating Lumbar Disc Herniation and Lumbar Spine Stenosis is safe and effective. The Percutaneous Transforaminal Endoscopic Lumbar Surgery has advantage as it is performed under local anesthesia with shorter length of hospitalization and early return to normal life. The clinical outcome of the patient that underwent Percutaneous Transforaminal Endoscopic Lumbar Surgery for Lumbar Disc Herniation and Lumbar Spine Stenosis is quite good in regard of its fewer complication and more benefits.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

Methods:80 patients with protrusion of lumbar intervertebral disc treated in our hospital between March 2013 and December 2015 were collected and divided into observation group and control group (n=40) according to randomized parallel contrast. Control group received traditional fenestration operation and observation group received percutaneous transforaminal endoscopic discectomy. Before operation and 1 week after operation, fluorescence spectrophotometry was used to determine serum pain medium levels;ELISA was used to determine pro-inflammatory factor and anti-inflammatory factor levels. Results:Before operation, differences in serum pain medium and inflammatory factor levels were not statistically significant between two groups (P>0.05). 1 week after operation, serum pain media norepinephrine (NE), dopamine (DA), 5-hydroxytryptamine (5-HT), prostaglandin E2 (PGE2) and substance P (SP) levels as well as pro-inflammatory factors interleukin-1β(IL-1β), interleukin-6 (IL-6), interleukin-18 (IL-18) and tumor necrosis factor alpha (TNF-α) levels of observation group were lower than those of control group (P<0.05) while serum anti-inflammatory factors interleukin-4 (IL-4), interleukin 10 (IL-10), soluble tumor necrosis factor receptor I (sTNF-RI) levels were higher than those of control group (P<0.05). Conclusions:Percutaneous transforaminal endoscopic discectomy can effectively treat protrusion of lumbar intervertebral disc and is more advantageous in alleviating patients’ perception of pain and reducing inflammation.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

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.
