Evaluation of Percutaneous Transforaminal Endoscopic Discectomy in the Treatment of Lumbar Disc Herniation: A Retrospective Study

摘要

Objective The objective of the present study was to evaluate the safety and efficacy of percutaneous transforaminal endoscopic discectomy (PTED) and open fenestration discectomy (OFD) in the treatment of lumbar disc herniation (LDH). Methods Patients in our hospital with LDH who received PTED ( n = 71) and OFD (n = 39) from 2013 to 2014 were retrospectively studied. Patient information, including age, gender, visual analogue scale (VAS) score for low back pain and leg pain, body weight, height, Oswestry disability index (ODI), Japanese Orthopedic Association (JOA), and recurrence, was collected. The patients in the two groups were followed up for an average of 63?months after surgery. Results A total of 136 patients completed the operation and 110 patients were followed up completely. There was no significant difference in baseline data between the two groups ( P ?0.05). The postoperative low back pain, leg pain, ODI, and JOA of the two groups were better than those preoperatively ( P ?0.05). At the end of the follow up, 89.7% (35/39) of patients in the OFD group had excellent improvement in the JOA score, and 88.7% (63/71) of patients in the PTED group had an excellent improvement. There was no significant difference between the two ( P ?0.05). There was also no significant difference in the recurrence rate between the two groups [(5/71) vs (3/39); P ?0.05]. [Correction added on 05 March 2021, after first online publication: “3/29” was amended to “3/39” in the preceding sentence.] Conclusion Both PTED and OFD can achieve good mid‐term efficacy in the treatment of LDH but PTED has certain advantages, including the small incision, a shorter hospital stay, and quicker, earlier recovery. However, prospective randomized controlled studies with a larger sample size are needed.
