We report a rare complication of iatrogenic spinal intradural following minimally invasive extradural endoscopic procedues in the lumbo-sacral spines. To our knowledge, intradural cyst following epiduroscopy has not been reported in the literature. A 65-year-old woman with back pain related with previous lumbar disc surgery underwent endoscopic epidural neuroplasty and nerve block, but her back pain much aggravated after this procedure. Postoperative magnetic resonance imaging revealed a large intradural cyst from S1-2 to L2-3 displacing the nerve roots anteriorly. On T1 and T2-weighted image, the signal within the cyst had the same intensity as cerebrospinal fluid. The patient underwent partial laminectomy of L5 and intradural exploration, and fenestration of the cystic wall was accomplished. During operation, the communication between the cyst and subarachnoid space was not identified, and the content of the cyst was the same as that of cerebrospinal fluid. Postoperatively, the pain attenuated immediately. Incidental durotomy which occurred during advancing the endoscope through epidural space may be the cause of formation of the intradural cyst. Intrdural cyst should be considered, if a patient complains of new symptoms such as aggravation of back pain after epiduroscopy. Surgical treatment, simple fenestration of the cyst may lead to improved outcome. All the procedures using epiduroscopy should be performed with caution.

Background: Neuroplasty using a Racz catheter or epiduroscope and percutaneous endoscopic laser discectomy are performed as treatment for chronic refractory low back and/or lower extremity pain, but they are limited in that they cannot completely remove the causing pathology. Lately, epiduroscopic laser neural decompression (ELND) has been receiving attention as an alternative treatment, but there are insufficient reports of results. Hence we aimed to investigate and report the data in our hospital. Methods: Seventy-seven patients were selected who had received ELND via the anterior and posterior epidural approach through the pain clinic in our hospital from March 2011 to July 2012. Their medical records including age, diagnosis, epiduroscopic findings and degree of symptom relief were investigated. The degree of symptom relief following the procedure was categorized into 5 stages of very good (5), good (4), no change (3), bad (2), and very bad (1) at 2 weeks and 1 month after the procedure. Results: The subjects were 30 males and 47 females. Mean age was 54.6 for males and 59.6 for females, so the overall mean age was 58.1 years old, with the youngest being 23 and the oldest 88 years old. In epiduroscopic images of all patients, more than one situation of herniated disc, fibrous tissue and adhesion, or inflammation was observed. Sixty-seven patients (87.0%) showed symptom relief 2 weeks after the procedure and 63 patients (81.8%) showed relief after 1 month. Conclusions: ELND is considered to be an effective treatment alternative for chronic refractory low back and/or lower extremity pain, including lumbar disc herniation, lumbar spinal stenosis, and failed back surgery syndrome which cannot be alleviated with existing non-invasive conservative treatment.

이 연구에서는 경막바깥신경성형술 시행에 있어서 중요한 엉치뼈틈새에서 경막주머니종말부 및 척수원뿔 사이의 거리를 자기공명영상에서 계측하여 한국인의 생체 연구에 대한 기초 자료를 제공하고자 한다. 허리통증으로 자기공명영상을 촬영한 환자 중 척추압박골절이나 척추전방전위증 그리고 기형 등이 없는 환자 200명(남자 88명, 여자 112명)을 대상으로 하였으며, 평균 연령은 54.3세(20~84세), 평균 신장은 161.3 cm(135~187 cm)이었다. T2강조 자기공명영상을 이용하여 엉치뼈틈새에서 경막주머니종말부 그리고 척수원뿔 사이 거리를 계측하여 성별 및 신장에 따른 상관관계를 분석하였다. 엉치뼈틈새꼭지에서 경막주머니종말부까지 거리는 $62.8{\pm}9.4mm$, 엉치뼈틈새꼭지에서 척수원뿔까지 거리는 $232.2{\pm}21.8mm$, 엉치뼈틈새꼭지에서 경막주머니종말부 사이 최소 거리는 34.8 mm, 최대 거리는 93.9 mm, 엉치뼈틈새꼭지에서 척수원뿔 사이 최소 거리는 155.0 mm, 최대 거리는 284.0 mm이었다. 엉치뼈틈새꼭지에서 경막주머니종말부까지, 그리고 엉치뼈틈새꼭지에서 척수원뿔까지 거리는 모두 여성이 남성보다 짧게 나타났고(p<0.05), 엉치뼈틈새꼭지에서 경막 종말부 및 척수원뿔 사이 거리는 신장에 대해 유의한 상관관계를 보였다(p<0.01). 이 연구의 결과는 한국 성인의 엉치뼈틈새에서 경막주머니종말부 및 척수원뿔 사이 거리에 대한 생체 계측 자료를 제공하며, 경막바깥공간에 대한 임상적 시술의 안전성 확보와 한국인의 체형에 맞는 카테터 개발에 도움이 될 것이라 생각한다.
