ABSTRACT
OBJECTIVE@#To investigate the clinical significance and related factors of drainage tube after percutaneous endoscopic lumbar discectomy(PELD).@*METHODS@#The clinical data of 151 patients with lumbar disc herniation who underwent PELD from January 2019 to September 2019 was retrospectively analyzed. According to whether the drainage tube was used after operation, the patients were divided into drainage tube group and non drainage tube group. The placement time and total drainage volume were recorded. The characteristics of patients, such as age, gender, body mass index, lumbar disc herniation segment, smoking history, basic diseases and whether taking anticoagulants, were analyzed by single factor and multiple factor.@*RESULTS@#Drainage tubes were used in 32 patients after PELD. There were statistical differences in visual analogue scale(VAS) and Japanese Orthopaedic Assiciation(JOA) scores between postoperative and preoperative of that in two groups(P<0.05). There were statistical differences in VAS and JOA scores at discharge between two groups(P<0.05), while there were no statistical differences at other time points(P>0.05). Univariate analysis showed that age, basic diseases and whether taking anticoagulants were related to the use of drainage tube, but gender, body mass index, lumbar disc herniation segment and smoking history were not significantly related to the use of drainage tube. Multivariate analysis showed that elderly patients, complicated with hypertension and diabetes, taking anticoagulants were related to the use of drainage tube.@*CONCLUSION@#The use of drainage tube after percutaneous endoscopic lumbar discectomy can improve the symptoms of lumbar and leg pain in early stage. For elderly patients with hypertension, diabetes and taking anticoagulants drugs, drainage tube can be considered after transforaminal endoscopy.

OBJECTIVES: To make a retrospective analysis and evaluate a clinical response to the control of disc degeneration related pain of 396 patients submitted to percutaneous lumbar nucleoplasty; and to make a record of visual analogical scale (VAS) up to a three-year follow-up after the surgical procedure. METHODS: Analysis of VAS score in 396 patients with lumbar disc degeneration related pain, according to anamnesis, clinical examination and magnetic resonance imaging (MRI), without improvement of previous clinical treatment, submitted to percutaneous nucleoplasty. RESULTS: A total of 26% of the patients presented 100% remission of pain or paresthesia, of whom 75% showed at least 50% of pain improvement. The median VAS pain improvement was about 67%. CONCLUSIONS: The median VAS improvement in inferior disc levels was higher than four points. The VAS showed improvement of the pain and paresthesia up to a three-year follow up after the surgical procedure.
OBJETIVOS: Analisar retrospectivamente a resposta clínica no controle da dor relacionada à degeneração discal em 396 pacientes submetidos à nucleoplastia percutânea lombar; e fazer um registro da escala analógica visual (EAV) com seguimento de três anos após a cirurgia. MÉTODOS: Análise da EAV de 396 pacientes com diagnóstico de hérnia de disco, de acordo com anamnese, exame clínico e imagens por meio de ressonância magnética (RM), sendo que nenhum deles apresentou melhora com tratamento clínico prévio. Estes pacientes foram submetidos à nucleoplastia percutânea. O estudo utilizou, para avaliação, o registro de escala analógica visual (EAV) durante seguimento de até três anos após o procedimento cirúrgico. RESULTADOS: Um total de 26% apresentou 100% de remissão da dor ou parestesia; 75% apresentaram pelo menos 50% de melhora da dor. A mediana da EAV de melhora da dor foi de aproximadamente 67%. CONCLUSÕES: Houve melhora da EAV, com mediana maior do que quatro pontos nos pacientes com acometimento nos níveis discais inferiores. A EAV mostrou melhora da dor e parestesia num período de seguimento de até três anos após o procedimento cirúrgico.
