ASPN Abstract: Evaluation of Safety and Efficacy of the Streamlined Technique vs the Standard Technique

Author— Dawood Sayed, MD Published July 22, 2021

The following study, “Evaluation of Safety and Efficacy of the Streamlined Technique vs the Standard Technique for Accessing Decompression Treatment Zones for the PILD Procedure,” investigates the safety and efficacy of the Streamlined Technique compared to the Standard Technique. While the PILD, or mild® Procedure, may be performed using both methods, the Streamlined Technique enables a single midline incision to access multiple treatment zones whereas the Standard Technique uses one incision per treatment zone. The study involved 243 patients that underwent the mild® Procedure using either technique and tracked their outcomes. The authors concluded that the Streamlined Technique does not compromise the safety or efficacy of the mild® Procedure. View the abstract poster below to learn why the Streamlined Technique is an innovative approach to consider.

Watch Dr. Dawood Sayed present his abstract from the American Society of Pain and Neuroscience’s (ASPN) Third Annual Conference, where he discusses how the study found that adopting the Streamlined Technique allowed for efficient and effective decompression of multiple treatment zones, without compromising the safety or efficacy of the mild® Procedure.

Hello, I’m Dr. Dawood Sayed and I’m a Professor of Anesthesiology and Pain Medicine at the University of Kansas. Today on behalf of my co-investigators, I’m gonna be presenting our abstract, an “Evaluation of the Safety and Efficacy of the Streamlined Technique vs the Standard Technique for Accessing Decompression Treatment Zones for the Percutaneous Interlaminar Lumbar Decompression (PILD) Procedure.” Our objectives were to investigate the safety and efficacy of the Streamlined Technique compared to the Standard Technique for the percutaneous image guided lumbar decompressive procedure. In summary, the Streamlined Technique is a single midline incision to access multiple treatment zones versus the more traditional standard techniques, in which multiple incisions are made to access multiple treatments zones. It was the hypothesis of the investigators, that using the Streamlined Technique, that we would be able to perform the procedure in an equal satisfactory manner with the same efficacy, but also performing the procedure in a much less invasive manner for the patient.

(01:03) So our methods were 243 patients with a baseline visual analog score of greater than five. These patients underwent the PILD Procedure at 1 or 2 treatment levels using either the Streamlined Technique which is about 136 patients, or the Standard Technique, which was about 107 patients. If you look at the table here, you can see that most of the patients were treated at either the L-3, L-4 or the L-4, L-5 levels. And again, the Streamlined Technique is a decompression performed using a single midline incision. The technique involves pulling back the portal to the subcutaneous tissue, and triggering tissue to change the level or side of treatment, to access and decompress multiple treatment zones through a single incision. When we look at our results, you can see the average pain level was around an 8 on a VAS mean score. When you look at the immediate pain relief and efficacy at around 2 weeks, you can see that the difference between the results and efficacy between the Standard Technique and the Streamlined Technique was almost identical. When you look at these patients a little further out at 1 to 3 months, again, you can see no difference in the outcomes in pain scores, as well as complication rates between the two arms when comparing the Streamlined and Standard Technique. So in conclusion, the Streamlined Technique does not compromise safety or efficacy of the PILD Procedure. We look forward to evaluating this in a more prospective, rigorous manner, to evaluate it as a true change in the way we do this procedure. Thank you.
