頸椎間盤(pán)突出的雙通道脊柱內(nèi)鏡手術(shù)技術(shù)要點(diǎn)和初步報(bào)告
Abstract：
Biportal endoscopic spine surgery (BESS) for cervical disk herniation (CDH) has been rarely reported. The aim of the article is to describe a novel BESS as a posterior approach for CDH and report the preliminary outcomes and complications. This singlecentered retrospective chart review included 109 consecutive patients who underwent BESS for symptomatic single-level CDH. Working and viewing portals were created in each unilateral paravertebral area at the target disk level. Endoscopic exploration allowed for effective and minimally invasive decompression via safe access to the medial foramen with minimal laminectomy and facetectomy. Clinical outcomes, including the visual analog scale, neck disability index, Macnab criteria, and the motor function of the involved arm, were evaluated at 4, 8, 12, and 24 postoperative weeks. Visual analog scale and neck disability index improved significantly at 24 weeks postoperatively (P < .01). According to the Macnab criteria, "excellent," "good," and "fair" results were obtained for 55.9%, 30.3%, and 13.8% of patients, respectively. The post 24-week distribution of the involved upper extremity strength grade was significantly improved compared to the initial value (P = .02). One patient had a motor weakness with a decreased grade over 4 weeks from excessive irrigation. The posterior approach of BESS was efficient and feasible for the treatment of CDH.
摘 要：
雙通道脊柱內(nèi)鏡手術(shù)(BESS)治療頸椎間盤(pán)突出(CDH)少有報(bào)道。這篇文章的目的是描述一種新的BESS雙通道脊柱內(nèi)鏡技術(shù)作為頸椎椎間盤(pán)突出的后入路，并報(bào)告初步結(jié)果和并發(fā)癥。這一單點(diǎn)入組的回顧性圖表回顧包括了109例因癥狀性單水平CDH而接受BESS的患者。在目標(biāo)椎間盤(pán)水平的每個(gè)單側(cè)椎旁區(qū)域建立工作和觀察入口。內(nèi)鏡探查允許通過(guò)安全進(jìn)入內(nèi)側(cè)孔進(jìn)行有效的微創(chuàng)減壓，并進(jìn)行最小椎板切除術(shù)和關(guān)節(jié)突切除術(shù)。在術(shù)后4、8、12和24周評(píng)估臨床結(jié)果，包括視覺(jué)模擬評(píng)分、頸部殘疾指數(shù)、Macnab標(biāo)準(zhǔn)和患者手臂的運(yùn)動(dòng)功能。術(shù)后24周，視覺(jué)模擬評(píng)分和頸部殘疾指數(shù)顯著改善(P <. 01)。根據(jù)Macnab標(biāo)準(zhǔn)，“優(yōu)秀”、“良好”和“一般”的結(jié)果分別為55.9%、30.3%和13.8%。24周后受累上肢強(qiáng)度等級(jí)分布較初始值有顯著改善(P = 0.02)。1例患者因過(guò)度沖洗4周后出現(xiàn)運(yùn)動(dòng)無(wú)力，且程度下降。BESS后入路是治療頸椎間盤(pán)突出癥有效可行的方法。
