Clinical effects of transforaminal and interlaminar percutaneous endoscopic discectomy for lumbar disc herniation: A retrospective study.
MEDICINE(2018)
Abstract
The aim of this study is to observe the therapeutic effect of percutaneous endoscopic discectomy and its influencing factors for lumbar disc herniation and compare the advantages and disadvantages of transforaminal and interlaminar of percutaneous endoscopy. Data from 143 patients with lumbar disc herniation were respectively collected, including demographic and clinical data. Study population were divided into curative effect group and poor curative effect group, and logistic regression was used to explore the influencing factors of curative effect. The operation data and pre-and post-operation scores were compared to explore the effect of transforaminal and interlaminar approach on surgery efficacy. The rate of curative effect was 93.7%. 120 patients were classified as curative group and 23 patients were categorized as poor effective group. Univariate analysis found that the patients in the curative effect group tended to receive the interlaminar approach (58.3% vs 34.8%, P=.038). Multivariate logistic regression did not find operation approach was not related to curative effect of operation (transforaminal and interlaminar). But age >= 45 (odd risk (OR)=6.43, P=.016), course of disease > 12 month (OR=3.77, P=.003), back and leg pain (OR=3.46, P=.026), history of trauma (OR=3.88, P=.014), Pfirrmann level IV (OR=4.84, P=.004), and pre-Visual Analogue Scale (VAS)<5.3 (OR=3.63, P=.015)were associated with operation efficacy. Compared with transforaminal group, the interlaminar group has less operative time (P=.000), less fluoroscopy time (P=.000), less puncture time (P=.000), less blood loss (P=.011). The transforaminal or interlaminar did not affect the treatment efficacy of percutaneous endoscopic discectomy for lumbar disc herniation. The selection of surgery approach depended on anatomical structure and physiological characteristics. It should be noted that 45 years of age or older, in the course of more than 12 months, both lumbocrural pain and lumbar disc herniation with grade IV, with history of trauma, may have impact on the efficacy of surgery.
