Retrospective review of prospectively collected data....
To describe the learning curve for percutaneous transforaminal endoscopic discectomy (PTED) and demonstrate its efficacy in treating lumbar disc herniation....
The learning curve for PTED has not yet been standardized in the literature....
Consecutive patients who underwent lumbar PTED by a single surgeon between December 2020 and 2022 were included. Cumulative sum analysis was applied to operative and fluoroscopy time to assess the lea...
Fifty-five patients were included. Cumulative sum analysis indicated that both operative and fluoroscopy time diminished rapidly after case 31, suggesting a learning curve of 31 cases (early phase: n ...
The PTED learning curve was found to be 31 cases and did not impact PROMs or complication rates. Although this learning curve reflects the experiences of a single surgeon and may not be broadly applic...
To explore the risk factors for residual symptoms following percutaneous endoscopic lumbar discectomy (PELD). A retrospective case-controlled study. From January 2015 to December 2020, consecutive pat...
Cervical conjoined nerve root is rare, and medical imaging, such as magnetic resonance imaging and computed tomography, cannot give an accurate preoperative diagnosis....
Evaluation of the impact of patients' participation on postoperative recovery and satisfaction who underwent the Percutaneous Endoscopic Interlaminar Discectomy(PEID)....
We collected data from sixty-nine patients who underwent PEID surgery at Chuzhou Chinese and Western Medicine Hospital between January 2020 and December 2022. All patients had L5/S1 lumbar disc hernia...
The communication group showed better pain control and functional recovery in the early postoperative period. The communication group had better VAS scores on the first day and month after surgery, as...
Preoperative surgical video viewing and intraoperative communication by PEID patients can alleviate pain, accelerate functional recovery, improve symptoms, and increase patients' satisfaction. We need...
This study aimed to evaluate the clinical efficacy and safety of percutaneous endoscopic interlaminar discectomy (PEID) for treating highly downward-migrated disc herniation....
We conducted a retrospective study on 39 patients with highly downward-migrated disc herniation who underwent PEID treatment between January 2015 and October 2020. The clinical outcomes, including the...
The mean operation time of PEID was 93.00(77.00,110.00) min, while that of PLIF was 169.00(157.00,183.00) min. Continued improvement in both PEID and PLIF was observed in the VAS and ODI scores immedi...
PEID has reliable efficacy and safety for treating highly downward-migrated disc herniation. And the long-term efficacy of PEID is comparable to PLIF. No severe complications occurred after surgery, a...
In recent years, with improved living standards, adolescent obesity has been increasingly studied. The incidence of lumbar disc herniation (LDH) in obese adolescents is increasing yearly. No clinical ...
This study aimed to evaluate the influence of herniation of cartilaginous endplates on postoperative pain and functional recovery in patients undergoing percutaneous endoscopic lumbar discectomy (PELD...
A retrospective analysis was conducted on 126 patients with LDH treated with PELD at the Third Hospital of Hebei Medical University from January 2021 to January 2022. Whether cartilaginous endplates h...
Patients with herniation of cartilaginous endplates experienced higher pain scores early postoperatively but showed significant improvement in pain and functional status over the long term. The back p...
Herniation of cartilaginous endplates significantly affect early postoperative pain and functional recovery in LDH patients undergoing PELD. These findings emphasize the need for clinical consideratio...
This study investigated the optimal concentration of ropivacaine epidural anesthesia for clinical use in percutaneous transforaminal endoscopic discectomy (PTED) by comparing the effects of different ...
Seventy patients scheduled for their first PTED procedure were enrolled in this randomized controlled trial. Patients were randomized to receive ropivacaine at varying concentrations (0.3% or 0.4%). P...
One patient withdrew due to severe postoperative complications. The remaining 69 patients were allocated to the 0.3% (n = 34) and 0.4% (n = 35) groups, respectively. Baseline characteristics showed no...
Although 0.4% ropivacaine (20 mL) impacts muscle strength, it does not impede PTED surgery. Given its effective analgesic properties and few postoperative complications, 0.4% ropivacaine can be consid...
This study was registered with the Chinese Clinical Trials Registry (Registration number: ChiCTR2200060364; Registration Date: 29/5/2022) and on chictr.org.cn ( https://www.chictr.org.cn/showproj.html...
Systematic Review....
To examine the impact of anesthesia type on patient-reported outcomes (PROs) and complications after percutaneous endoscopic lumbar discectomy (PELD)....
A significant advantage of PELD involves the option to use alternative sedation to general anesthesia (GA). Two options include local anesthesia (LA) and epidural anesthesia (EA). While EA is more inv...
A systematic review and meta-analysis of the PubMed, EMBASE, and SCOPUS databases examining PELD performed with LA or EA from inception to August 16, 2021 were conducted. All studies reported greater ...
Fifty-six studies consisting of 4465 patients (366 EA, 4099 LA) were included. Overall complication rate, durotomy rate, length of stay, recurrent disk herniation, and reoperation rates were similar b...
EA can be a safe and feasible alternative to LA, potentially minimizing patient discomfort during PELD. Conclusions are limited by a high level of study bias and heterogeneity. Further investigation i...
This study aimed to evaluate the effect of foraminoplasty using large-channel endoscopy during TESSYS on the biomechanics of the lumbar spine....
A complete lumbar spine model, M1, was built using 3D finite elements, and models M2 and M3 were constructed to simulate the intraoperative removal of the superior articular process of L5 using a trep...
Compared with the M1 model, the M2 and M3 models showed decreased stress at the L4-5 left FJ and a significant increase in stress at the right FJ in forward flexion. In the M2 and M3 models, the L4-5 ...
Foraminoplasty using large-channel endoscopy could increase the stress on the FJ and disc of the surgical segment, which suggested unnecessary and excessive resection should be avoided in PTED to mini...
