ABSTRACT
OBJECTIVE@#To observe the effect of acupotomy on the fat infiltration degree of lumbar multifidus muscle (LMM) in patients with lumbar disc herniation after percutaneous transforaminal endoscopic discectomy (PTED).@*METHODS@#A total of 104 patients with lumbar disc herniation treated with PTED were randomly divided into an observation group (52 cases, 3 cases dropped off) and a control group (52 cases, 4 cases dropped off). Patients of both groups received rehabilitation training of two weeks 48 h after PTED treatment. The observation group was treated with acupotomy (L3-L5 Jiaji [EX-B 2]) once within 24 h after PTED. In the two groups, the fat infiltration cross sectional area (CSA) of LMM was compared before and 6 months after PTED, the visual analogue scale (VAS) score and Oswestry disability index (ODI) score were observed before and 1, 6 months after PTED. The correlation between fat infiltration CSA of LMM in each segment and VAS score was analyzed.@*RESULTS@#Six months after PTED, the fat infiltration CSA of LMM in L4/L5 and the total L3-S1 segments of the observation group was lower than that before PTED (P<0.05), and the fat infiltration CSA of LMM in L4/L5 of the observation group was lower than the control group (P<0.01). One month after PTED, the ODI and VAS scores of the two groups were lower than those before PTED (P<0.01), and those in the observation group were lower than the control group (P<0.05). Six months after PTED, the ODI and VAS scores of the two groups were lower than those before PTED and 1 month after PTED (P<0.01), and those in the observation group were lower than the control group (P<0.01). There was a positive correlation between the fat infiltration CSA of LMM in the total L3-S1 segments and VAS scores in the two groups before PTED (r = 0.64, P<0.01). Six months after PTED, there was no correlation between the fat infiltration CSA of LMM in each segment and VAS scores in the two groups (P>0.05).@*CONCLUSION@#Acupotomy can improve the fat infiltration degree of LMM, pain symptoms and activities of daily living in patients with lumbar disc herniation after PTED.

ABSTRACT Objective To analyze the results of the use of dexmedetomidine (D) in the treatment of patients with degenerative diseases of the lumbar spine using puncture techniques. Methods The study included 77 patients who underwent surgical puncture for degenerative diseases of the lumbar spine with the use of alpha-2-adrenomimetic D: percutaneous laser denervation of the facet joints (n = 46) and posterolateral transforaminal endoscopic discectomy (n = 31). We assessed: the level of sedation using the Ramsay Sedation Scale (RSS) and the Richmond Agitation Sedation Scale (RASS); intraoperative dynamics of the cardiovascular and respiratory system parameters; the level of pain syndrome according to VAS. Results A high intraoperative level of sedation was determined, with RASS -2, -3 and Ramsay III, IV; when transferring a patient to a department (in 90 minutes) this parameter was RASS 0 and Ramsay II. There were no significant changes in central hemodynamics and respiratory depression. The minimum level of pain was determined immediately after surgery, at 30 and 60 minutes after surgery, and before transfer to the department (90 minutes): 6 (4;9); 10 (8;12); 12 (9;13); 16 (13;19) respectively. The absence of the need for additional analgesia on the first postoperative day was verified. Conclusion The use of D significantly reduces the level of pain, while maintaining the necessary verbal contact with the patient, and provides the necessary neurovegetative protection without respiratory depression or lowered hemodynamic parameters during the perioperative period.

BACKGROUND: Lumbar percutaneous transforaminal endoscopic discectomy can decompress nerve root compression caused by herniated lumbar disc. Postoperative rehabilitation not only includes the recovery of surgical trauma, but also the recovery of lumbar muscle damage accompanied by lumbar disc herniation and the recovery of pelvic-leg function imbalance. OBJECTIVE: To evaluate the effectiveness and feasibility of staged rehabilitation program of lumbar motor chain based on McKenzie’s technique after lumbar percutaneous transforaminal endoscopic discectomy. METHODS: Totally sixty-two patients with lumbar disc herniation who were treated in the Beijing Bo’ai Hospital of China Rehabilitation Research Center from January 2012 to December 2018 underwent percutaneous transforaminal endoscopic discectomy. The patients were randomly divided into experimental group and control group, 31 cases in each group. The experimental group performed remote staged rehabilitation guidance based on McKenzie’s technology according to pre-set rehabilitation program for postoperative rehabilitation of lumbar motion chain: 2-6 weeks after operation as the first stage, 7-12 weeks as the second stage and 13-24 weeks as the third stage. Control group received regular postoperative rehabilitation. Visual analogue scale score, Japanese Orthopaedic Association score, Oswestry Disability Index, and SF-36 score were assessed in both groups pre-rehabilitation and 6, 12, and 24 weeks post-rehabilitation. Cross sectional area of the multifidus of the lumbar spine was detected under MRI 12 weeks post-rehabilitation. Gait analysis was conducted 24 weeks post-rehabilitation by using three-dimensional motion acquisition and analysis system. This study was approved by the Ethics Committee of Beijing Bo’ai Hospital of China Rehabilitation Research Center (approval No. 2019-011-1). RESULTS AND CONCLUSION: (1) After rehabilitation, visual analogue scale score, Japanese Orthopaedic Association score, Oswestry Disability Index, and SF-36 score were improved to different degrees in both groups compared with those before rehabilitation. Visual analogue scale score and Oswestry Disability Index were lower in the experimental group than those in the control group at 6 and 12 weeks (P 0.05). (3) Gait analysis exhibited that the ratio of left to right in the supporting phase of the experimental group was higher than that of the control group at 24 weeks (P < 0.05). (4) Results suggest that the staged rehabilitation program after percutaneous transforaminal endoscopic discectomy for lumbar disc herniation is in line with the characteristics of postoperative recovery of lumbar disc herniation, and has good effectiveness and feasibility.
ABSTRACT
Objective::To observe the clinical efficacy of modified Buyang Huanwu Tang on patients with lumbar disc herniation (LDH) after percutaneous foramen endoscopy by the collateral disease theory, and its effect on inflammatory factors and pain-inducing mediators. Method::One hundred and forty-four patients were randomly divided into control group (72 cases) and observation group (72 cases) by random number table. Both groups’ patients were treated with percutaneous endoscopic lumbar discectomy(PELD), and symptomatic treatment dehydration and anti-inflammation were also given to those patients after the operation. Patients in observation group got modified Buyang Huanwu Tang, 1 dose/day. The course of treatment was 4 weeks, and a 12-week fellow-up was recorded. Before the operation and at the 3rd day, the 4th and 16th week after the operation, scores of visual analogue score of pain degree (VAS) were recorded. And before the operation and at the 1st, 4th and 16th week after the operation, scores of dysfunction index (ODI) of Oswestry were recorded. Failed back surgery syndrome of LDH was recorded during 16 weeks after the operation. And Japanese orthopaedic association (JOA) and Qi deficiency and blood stasis syndrome were scored. And the levels of prostaglandin E2 (PGE2), thromboxane B2 (TXB2), interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha) and serotonin (5-HT) were all detected, and the effect was assessed by improved Macnab. Result::At the 1st day and the 1st, 4th and 16th week after treatment, scores of VAS were all lower than those in control group (P<0.01). And at the 1st, 4th and 16th week after treatment, scores of ODI were lower than those in control group (P<0.01). The rate of incidence was 18.06%(13/72), which was lower than 37.5%(27/72) in control group (χ2=6.784, P<0.01). Scores of the total JOA and subjective symptoms, objective signs and daily activities were all higher than those in control group (P<0.01). And scores of symptom scores and total scores of deficiency and blood stasis syndrome were all lower than those in control group (P<0.01). After treatment, levels of TNF-α, IL-1β, PGE2, TXB2 and 5-HT were lower than those in control group (P<0.01). According to the rank sum test, the effect of modified Macnab was better than that in control group (Z=2.151, P<0.05). Conclusion::Based on Luobing theory, modified Buyang Huanwu Tang can alleviate pain and other symptoms, promote the recovery of lumbar vertebral function, inhibit the expressions of inflammatory factors and pain-causing mediators, alleviate the residual symptoms after recent operation, reduce the incidence of FBSS, promote the rehabilitation of patients after operation, and improve the efficacy.
ABSTRACT
The lumbar disc herniation is a common and recurrent disease in the department of orthopedics. At present, the treatment means mainly include conservative treatment and surgical treatment. Compared with traditional open surgery, percutaneous transforaminal endoscopic discectomy (PTED) is safe, effective, economical and minimally invasive. It is widely used in minimally invasive treatment of lumbar disc herniation. However, the clinical reports of the failure of PTED are also common. According to the research reports of domestic and foreign scholars, there are varieties of risk factors for surgical failures, including the selections of patients, indications, surgical approaches and anesthesia methods preoperative. Occurrences of surgical complications including infection or left pains, and reasonable rehabilitation exercise after the operation are related to failures. There is no unified conclusion at present. In this paper, we reviewed the literatures about failed PTED, and try to make an overview about the general situation of failed operation in clinical practice, the risk factors for failures and the countermeasures.

ABSTRACT
Objective To explore clinical efficacy of percutaneous tiansforaminal endoscopic discectomy on postoperative complications of patients with the protrusion of lumbar intervertebral disc.Methods Sixty cases of lumbar protrusion of the intervertebral disc were selected as our subjects from Nov.2012 to Nov.2013 who were hospitalized in the Seven People's Hospital of Zibo.Of which,30 cases were preformed lumbar protrusion of the intervertebral disc through transforaminal endoscopic treatment.Another 30 case were with small incision fenestration laminectomy discectomy.The information of hospitalized periods,bleeding volume,operation incision length and periods within the bed were collected.Visual analogue scale (VAS) was performed at postoperative 24,48 h.The Oswestry disability index (ODI) was applied to evaluated the daily life ability assessment of patients before surgery,1 month and 6 months after surgery.Results The incision length,intraoperative bleeding volume,postoperative bed and hospitalization periods in patients with transforaminal endoscopic treatment were ((0.7 ± 0.2) cm,(11.6 ± 2.2) ml,(27.5 ± 8.2) d,(3.3 ± 1.1) d respectively,less than that in patients with small incision fenestration laminectomy discectomy ((4.9 ± 0.2) cm,(102.9 ±16.3) ml,(94.1 ±19.7) d,(8.3 ±2.1) d).The differences were significant (t =81.332,30.403,17.095 and 11.552;P＜0.05).VAS in patients with transforaminal endoscopic treatment and in patients with small incision fenestration laminectomy discectomy were (3.7 ± 1.2) and (6.8 ± 1.9),(2.1 ± 1.1) and (5.3 ±1.6),(1.4 ±0.9) and (4.4 ± 1.5) respectively,and the differences were significant(t =7.555,9.026,9.393 ; P ＜ 0.05).The ODI in patients with transforaminal endoscopic treatment at 1 and 6 months after surgery were 12.1 ± 4.7 and 18.6 ± 3.6,higher than that in patients with small incision fenestration laminectomy discectomy(5.4 ± 2.3,13.2 ± 2.7),and the differences were significant (t =6.013,12.045 ; P ＜ 0.05).Conclusion Lumbar percutaneous transforaminal endoscopic discectomy is with obvious superiority than the method of small incision fenestration laminectomy discectomy in terms of the operation incision,intraoperative bleeding volume,postoperative bed and hospitalization time.Meanwhile,it shows the less damage to the spinal stability structure,and quick recovery.
ABSTRACT
Objective To investigate the value of percutaneous transforaminal endoscopic spine system (TESSYS) in lumbar discectomy for disc herniation. Methods Thirty one patients with lumbar disc herniation were treated with TES-SYS and followed up 6-12 months. The involved levels of vertebral segment included L34 (2 cases), L45 (21 cases) and L5S1 (8 cases). The targeted puncture was performed under local anesthesia and fluoroscopic guidance. The foramen of involved level of vertebral segment was enlarged gradually with four trephinations, and the working cannula was inserted transforaminal in-to the canal. Then the herniation was exposed and removed with full endoscopic technique, including the loosen nucleus pulposus. The nerve root and dural sac were exposed and released adequately. Results The procedure was evenly carried out in 27 cases. After discectomy, the nerve roots were complete released, and not exposed in the first case of far lateral herni-ation and the second case of central herniation. The third case and eleventh case converted to microendoscopic discectomy, due to large herniation and intraoperative pain, respectively. The patients could walk in the same day, 1 or 2 days after opera-tion, with obvious relief of leg pain. One case of recurrence was found at 2 weeks after operation, who was treated conserva-tively. At the final follow-up, the visual analogue scale of leg pain decreased from 8.1±1.9 to 1.1±0.9, and the Oswestry dis-ability index (ODI) decreased from 31.1±8.3 to 3.4±3.3. According to MacNab scale, there were excellent results in 25 cases and good results in 6 cases. Conclusion The percutaneous endoscopic TESSYS is a good minimal invasive technique for lumbar discectomy, with good results and a learning curve.
ABSTRACT
STUDY DESIGN: A retrospective study. PURPOSE: To determine the feasibility and effectiveness of revisional percutaneous full endoscopic discectomy for recurrent herniation after conventional open disc surgery. OVERVIEW OF THE LITERATURE: Repeated open discectomy with or without fusion has been the most common procedure for recurrent lumbar disc herniation. Percutaneous endoscopic lumbar discectomy for recurrent herniation has been thought of as an impossible procedure. Despite good results with open revisional surgery, major problems may be caused by injuries to the posterior stabilized structures. Our team did revisional full endoscopic lumbar disc surgery on the basis of our experience doing primary full endoscopic disc surgery. METHODS: Between February 2004 and August 2009 a total of 41 patients in our hospital underwent revisional percutaneous endoscopic lumbar discectomy using a YESS endoscopic system and a micro-osteotome (designed by the authors). Indications for surgery were recurrent disc herniation following conventional open discectomy; with compression of the nerve root revealed by Gadolinium-enhanced magnetic resonance imaging; corresponding radiating pain which was not alleviated after conservative management over 6 weeks. Patients with severe neurologic deficits and isolated back pain were excluded. RESULTS: The mean follow-up period was 16 months (range, 13 to 42 months). The visual analog scale for pain in the leg and back showed significant post-treatment improvement (p < 0.001). Based on a modified version of MacNab's criteria, 90.2% showed excellent or good outcomes. There was no measurable blood loss. There were two cases of recurrence of and four cases with complications. CONCLUSIONS: Percutaneous full-endoscopic revisional disc surgery without additional structural damage is feasible and effective in terms of there being less chance of fusion and bleeding. This technique can be an alternative to conventional repeated discectomy.

OBJECTIVE: The objectives of this study were to determine the frequency of symptomatic postdiscectomy pseudocyst (PP) after endoscopic discectomy and to compare the results of surgical and conservative management of them. METHODS: Initial study participants were 1,503 cases (1,406 patients) receiving endoscopic lumbar discectomy by 23-member board of neurosurgeons from March 2003 to October 2008. All patients' postoperative magnetic resonance imaging (MRI) scans were evaluated. On the postoperative MRI, cystic lesion of T2W high and T1W low at discectomy site was regarded as PP. Reviews of medical records and radiological findings were done. The PP patients were divided into two groups, surgical and conservative management by treatment modality after PP detection. We compared the results of the two groups using the visual analogue scale (VAS) for low back pain (LBP), VAS for leg pain (LP) and the Oswestry disability index (ODI). RESULTS: Among 1,503 cases of all male soldiers, the MRIs showed that pseudocysts formed in 15 patients, about 1.0% of the initial cases. The mean postoperative interval from surgery to PP detection was 53.7 days. Interlaminar approach was correlated with PP formation compared with transforaminal approach (p=0.001). The mean VAS for LBP and LP in the surgical group improved from 6.5 and 4.8 to 2.0 and 2.3, respectively. The mean VAS for LBP and LP in the conservative group improved from 4.4 and 4.4 to 3.9 and 2.3, respectively. There was no difference in treatment outcome between surgical and conservative management of symptomatic PP. CONCLUSION: Although this study was done in limited environment, symptomatic PP was detected at two months' postoperative period in about 1% of cases. Interlaminar approach seems to be more related with PP compared with transforaminal approach.

The percutaneous endoscopic lumbar discectomy (PELD) is already being applied to treat almost all types of lumbar disc herniations, ranging from soft contained disc herniation, to migrated disc herniation, and eventually to foraminal and extraforaminal disc herniations. Its concept has already shifted from an indirect central decompression to a direct epidural targeted fragmentectomy with its clinical outcomes comparable to those of conventional open surgery. However, despite the good surgical outcomes reported for this endoscopic procedure for various lumbar spinal pathologies, its procedure still appears to be somewhat complicated for most spine surgeons. This phenomenon might be attributable to the fact that, apart from the technical aspect of the procedure, the surgeons are not familiar with the proper selection of patients. In this article, we have dealt with the basic principle and technique for various surgical conditions. Although these descriptions are totally based on our experiences and therefore have not been statistically analyzed.

STUDY DESIGN: Retrospective study OBJECTIVES: This study examined the post-operative results of interlaminar percutaneous endoscopic lumbar discectomy (PELD) with or without endoscopic laminotomy in lumbar disc herniation. SUMMARY OF LITERATURE REVIEW: In addition to the technical feasibility, the indications of PELD surgery are usually the same as those for open discectomy. MATERIALS AND METHODS: From January 2005 to August 2006, 62 cases treated with PELD using an interlaminar approach due to lumbar disc herniation were examined. The mean age of the subjects was 40.1 years (18-70) and the mean follow up period was 32.6 months (24-44). Thirty-four and 28 herniated discs were extracted from L4-L5 and L5-S1, respectively. The clinical results were evaluated using MacNab's criteria. RESULTS: The herniated discs were accessible in all cases. Excellent and good results were obtained in 85% (53 cases) of patients but 15% of patients (9 cases) showed unsatisfactory results or needed revision. There were 4 cases of incomplete removal, 2 cases of recurrence and 4 cases of persistent low back pain due to associated degenerative pathologies. Additional surgery was required in 7 cases which were open discectomy in 5 cases (3 cases of 4 incomplete removal and 2 of recurrence). There was one case of PLIF and 1 additional decompression. Cauda equina syndrome occurred in one case who underwent subsequent wide decompression and open discectomy. CONCLUSIONS: interlaminar PELD using endoscopic laminotomy is an effective method for treating lumbar disc herniation with moderate up and down migration. The clinical success rate can be improved by selecting patients with accessible discs and excluding those with an associated pathology.

STUDY DESIGN: A retrospective study. OBJECTIVES: We report the efficacy of the entry point and approach angle of a working cannula using preoperative prone abdominal computer tomography (PACT). SUMMARY OF LITERATURE REVIEW: To date, there are no reports on the entry point and approach angle of a working cannula when performing transforaminal percutaneous endoscopic lumbar discectomy (TPELD) with consideration of the individual anatomic variations and characteristics of herniated disc and surgical instruments. MATERIALS AND METHODS: Cases of herniated intervertebral discs from L4-5, who have previously undergone PACT before TPELD, were included. A total of 25 patients were observed over a 1 year period. The entry point and approaching angle of the working cannula with PACT were calculated, and the results were applied to the TPELD. The clinical results were assessed 1 month after surgery using the VAS, ODI and MacNab criteria, and were confirmed by a radiology and MRI examination. RESULTS: The preoperative measured data using PACT showed that the mean approaching distance and mean approaching angle of the working cannula were 12.4 cm and 75.4 degree, respectively. The VAS improved from a mean of 8.1 preoperatively to a mean of 2.3 12 months after surgery. The ODI improved from a mean of 59 preoperatively to a mean of 24 at 12 months after surgery. According to the MacNab criteria, all patients were classified as either excellent and good during the follow up periods. The extruded disc of all patients had been well removed according to the MRI scan performed 1 month after surgery. CONCLUSIONS: The scientific approach method using PACT based on the characteristics of patients and surgical instruments can be performed easily and accurately, and access and decompress the extruded disc directly.
