Comparison of conventional fenestration discectomy with Transforaminal endoscopic lumbar discectomy for treating lumbar disc herniation:minimum 2-year long-term follow-up in 1100 patients Quanyi Li and Yongchun Zhou*
Abstract Purpose: To compare the efficacy of conventional interlaminar fenestration discectomy (IFD) with transforaminal endoscopic lumbar discectomy (TELD) for treating lumbar disc herniation (LDH). Methods: The clinical data of 1100 patients who had been diagnosed with LDH between January 2012 and December 2017 were retrospectively analysed. IFD was performed on 605 patients in Group A, whereas TELD was performed on 505 patients in Group B. The Oswestry Disability Index, Visual Analogue Scale for pain and modified MacNab criteria were used to evaluate the outcomes. The surgery duration, intraoperative blood loss, postoperative off-bed activity and postoperative length of hospital stay were recorded. Results: The follow-up period ranged from 24 to 60 months, with an average of 43 months. The excellent and good outcome rates were 93.5% in Group A and 92.6% in Group B. There was no significant difference in efficacy between the groups (P > 0.05). However, Group B had significantly less intraoperative blood loss and shorter bed rest duration and postoperative length of hospital stay than Group A (P < 0.05). There were two cases of postoperative recurrence in Group A and three in Group B. Conclusions: Although conventional IFD and TELD had similar levels of efficacy in treating LDH, TELD had several advantages. There was less intraoperative bleeding, shorter length of hospital stay and shorter bed rest duration. It can be considered a safe and effective surgical option for treating LDH.

Introduction Lumbar disc herniation (LDH) is a condition in which the spine deteriorates and herniation of the intervertebral disc occurs. It is commonly observed in orthopaedic clinics and can cause severe symptoms, including lower back pain and sciatica, which greatly * Correspondence: [email protected] Department of Orthopedic, Shaanxi Provincial People’s Hospital, 256# You-yi West Road, Xi’an 710068, Shaanxi, People’s Republic of China
impact patients’ daily lives. Most patients are admitted to hospital [1]. Conservative treatment is often preferred for LDH, but patients who fail to respond to this are treated with surgery [2]. Surgical treatment aims to remove the herniated nucleus pulposus to the largest extent possible to relieve nerve compression while minimising spinal instability [3]. Interlaminar fenestration discectomy (IFD) is the most commonly performed
