I would like to thank Dr. Jo for his interest and concerns regarding the transforaminal epiduroscopic laser annuloplasty (TELA)
It is very well known that that provocative discography is a very useful diagnostic tool for confirming the pathologic level for discogenic low back pain. In cases of multilevel annular tear lesions on magnetic resonance imaging, provocative discography was performed. Occasionally, in cases where a lesion was at one level and could be clearly seen, we skipped discography. Also, disc herniation was excluded, and internal disc disruption was included in our study.
TELA and percutaneous endoscopic lumbar discectomy (PELD) are completely different. The main focus of PELD is the removal or decompression of the herniated disc. On the other hand, TELA refers to equipment that is used to perform an annuloplasty. A TELA working sheath cannot be inserted into the disc to observe its interior like an endoscope. The intradiscal procedure (granulation tissue removal) of TELA is performed under the C-arm. The PELD working sheath is placed half intradiscally and half epidurally. Both the intradiscal and extradiscal procedure are fully performed under endoscopic guidance. In addition, TELA uses a small working channel (outer diameter, 3.5 mm) compared with the PELD working sheath (more than 5 mm). Studies using percutaneous endoscopic annuloplasty (modified PELD) have been published [2,3]. This procedure is performed on the disc. A comparative study of the two procedure (TELA
Normally, IDRA is performed under the C-arm. However, in our hospital, we have a LASE® kit (Clarus Medical LLC, Minneapolis, MN). So, we performed it under the C-arm and LASE® kit. Sometimes, we have used the epiduroscope.
The terminology is believed to require further discussion.
