A Novel Balloon-Inflatable Catheter for Percutaneous Epidural Adhesiolysis and Decompression

Epidural adhesions cause pain by interfering with the free movement of the spinal nerves and increasing neural sensitivity as a consequence of neural compression. To remove adhesions and deliver injected drugs to target sites, percutaneous epidural adhesiolysis (PEA) is performed in patients who are unresponsive to conservative treatments. We describe four patients who were treated with a newly developed inflatable balloon catheter for more effective PEA and relief of stenosis. In the present patients, treatments with repetitive epidural steroid injection and/or PEA with the Racz catheter or the NaviCath did not yield long-lasting effects or functional improvements. However, PEA and decompression with the inflatable balloon catheter led to maintenance of pain relief for more than seven months and improvements in the functional status with increases in the walking distance. The present case series suggests that the inflatable balloon catheter may be an effective alternative to performing PEA when conventional methods fail to remove adhesions or sufficiently relieve stenosis.

The Comparison of the Result of Epiduroscopic Laser Neural Decompression between FBSS or Not

BACKGROUND: Epiduroscopic laser neural decompression (ELND) has been performed as a treatment tool for chronic refractory low back pain and/or radicular pain. There are some studies about the usefulness of epiduroscopy for post lumbar surgery syndrome, however, few studies about the effectiveness of epiduroscopy for patients without back surgery. We compared the satisfaction of patients who underwent ELND for chronic low back pain and/or radicular pain after back surgery and for the same symptoms without surgery. METHODS: We compared the degree of satisfaction of patients after ELND between who had underwent the lumbar spine surgery and who had not retrospectively by chart reviewing. We divided 39 patients who had received ELND into two groups, one is the group of patients who got the lumbar surgery (group 1), and the other is the group of patients who did not (group 2). Their medical records including age, sex, previous treatment, duration of illness, degree of symptom relief were investigated. We compared each items between two groups. RESULTS: The number of patients in group 1 was 17, and group 2 was 22. In group 1, 16 patients (94.1%) showed more than 'Acceptable', and 19 patients (86.4%) showed more than 'Acceptable' in group 2. There is no significant differences statistically in percentage of patients who showed more than 'Acceptable' in the satisfaction after ELND between two groups. CONCLUSIONS: ELND provided satisfaction (more than 85%) for patients with chronic low back pain and/or leg pain regardless of previous back surgery history.
