| description | Abstract Background This study aimed to evaluate the clinical efficacy and learning curve of percutaneous endoscopic cervical discectomy (PECD) in treating patients with symptomatic cervical spondylotic radiculopathy (CSR). Methods A total of 105 patients with single-segment symptomatic CSR treated between January 2020 and January 2022 were retrospectively analyzed and divided into PECD and ACDF groups based on the surgical approach. Patient demographics, operation time, estimated intraoperative blood loss, complications, postoperative hospital stay, total hospitalization cost, neck dysfunction index (NDI), arm and neck visual analog scale (VAS) scores were compared and analyzed. The learning curve of the PECD group was assessed using cumulative sum (CUSUM) analysis. Results There was no statistically significant difference in baseline data between the two groups (P > 0.05). The PECD group had shorter operative time, smaller incision length, less estimated intraoperative bleeding, lower total hospitalization costs, and shorter postoperative hospital stays compared to the ACDF group (P < 0.05). Postoperative NDI, arm VAS, and neck VAS scores improved significantly in both groups compared to preoperative values (P < 0.05). However, no significant difference was found between the two groups during the same period (P > 0.05). There were also no significant differences between the PECD and ACDF groups in the number of intraoperative fluoroscopies, complications, or surgical success rates (P > 0.05). As more cases accumulated, a trend toward shorter operative times was observed in the PECD group. When grouped according to the learning curve, with the 23rd case as the cutoff point, there was no significant difference in clinical outcomes between the learning phase and proficient phase groups (P > 0.05). Conclusions PECD is a safe and effective procedure for treating single-segment CSR, offering clinical outcomes comparable to ACDF. PECD has a notable learning curve, requiring beginners to perform 23 cases to reach proficiency. However, longer operative times do not negatively impact preclinical outcomes. Trial registration Retrospectively registered. |
