In order to evaluate the incidence of soft tissue changes after automated lumbar nucleotomy, a prospective cohort study was performed with follow-up CT within four to six hours after treatment of 97 discs in 88 patients. The CT scans were normal at 47 levels and abnormal at 50. At 11 levels traces of blood were seen along the trajectory, of which nine were located in the subcutaneous fat, one in the extensor and one in the psoas muscle. Small gas collections were observed at 42 levels. Twenty-one of them were located in the extensor and two in the psoas muscle, seven in the subcutaneous fat, two in the epidural space and ten in multiple locations. The abnormal scans were not associated with clinical symptoms different from those with normal scans. The results support previous reports indicating that this procedure is associated with low morbidity and complication rates.
为了评估自动腰椎间盘切除术术后软组织变化的发生率，我们进行了一项前瞻性队列研究，对88例患者的97个椎间盘进行治疗后4至6小时内进行随访CT检查。CT扫描结果显示，47个层面正常，50个层面异常。在11个层面的手术路径上可见血迹，其中9个位于皮下脂肪层，1个位于伸肌，1个位于腰大肌。在42个层面观察到小的气体聚集。其中21个位于伸肌，2个位于腰大肌，7个位于皮下脂肪层，2个位于硬膜外间隙，10个位于多个部位。异常扫描结果与正常扫描结果相比，并未出现不同的临床症状。这些结果支持了先前的报告，表明该手术的发病率和并发症发生率较低。
