Performed under local anesthesia, TPED has been proven to be a safe and effective technique which has been also associated with shorter rehabilitation period, reduced blood loss, trauma, and scar tissue compared to conventional procedures. However, the procedure should be performed by a spine surgeon experienced in the specific technique and capable of recognizing or avoiding various challenging conditions. In this review, pitfalls that a novice surgeon has to be mindful of, are reported and analyzed.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

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

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

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
