ASPN Abstract: Single-Center Comparison of Streamlined Technique Safety for mild® Procedure

Author— Navdeep Singh Jassal, MD and Christine Christensen, MSN, APRN Published July 22, 2021

The following study, “Single-Center Comparison of Streamlined Technique Safety for mild® Procedure: Measuring Incidence of Postoperative Complications Compared to Standard Approach,” evaluates the safety of the Streamlined Technique in patients treated consecutively by a single center. As the mild® Procedure has become more widespread in clinical practice, there has been an evolution from the Standard Approach to the Streamlined Technique, a less invasive procedural approach. Dr. Navdeep Jassal and Christine Christensen, MSN, APRN, of the Spine & Pain Institute of Florida, evaluated 78 mild® patients treated using either the Streamlined Technique or the Standard Approach and measured the occurrence of postoperative complications. View the abstract poster below to discover the results of this study, and learn why the mild® Procedure should be considered the first-line intervention for patients with lumbar spinal stenosis after conservative treatments have been exhausted.

Hello, my name is Navdeep, Dr. Navdeep Jassal from the Spine Institute of Florida in Lakeland, Florida. I’m here to discuss a little bit about a study that is very meaningful to myself and especially my patients in my practice. We’re going to talk a little bit about the Streamlined Approach for the minimally invasive lumbar decompression or the mild® Procedure, and how that’s really changed the way I’ve practiced. We’re going to talk specifically about the safety profile for this particular technique and its comparison to the standard or the classical approach that we’ve used for years.

So what we did was we did a retrospective chart review on our patients and we just wanted to measure the incidence of postoperative complications of the Streamlined Technique compared to the Standard Approach. And we know that the Standard Approach is a very safe as well as an efficacious procedure, and we’ve seen this really time and time again, but classically we’ve seen this from the RCT from the MiDAS ENCORE study, which showed the approach of the Standard Approach, comparing the epidural steroid injection, which is the standard procedure that you do for patients with lumbar spinal stenosis with neurogenic claudication. And then comparing that with the mild® or the minimally invasive lumbar decompression procedure.

I wanted to take this a step further and I wanted to make sure that the complication rate was pretty much the same, which was extremely rare, comparing the Streamlined Approach with the Standard Approach and that’s simply what we did in this retrospective chart review in our practice. I’m going to turn it over to Christine Christensen, who is going to talk a little bit about the data and dive really further into the data because I think it’s just quite interesting.

Hi, I’m Christine Christenson. I’m the Nurse Practitioner that works with Dr. Jassal here in Lakeland, Florida. As part of my practice here, Dr. Jassal was able to include me in generating data and analyzing that data for our research study here looking at the efficacy and safety of the Streamlined Technique. Now, data collection for this study consisted of reviewing charts on 78 patients that had the mild® Procedure performed for them. Dr. Jassal started doing the Streamlined Technique after certain dates.

So we looked at the date and the operative notes for those patients to verify that they did get the Streamlined Technique in the operating room. Of those patients, 100% had confirmed central spinal stenosis on MRI. They also had ligamentum flavum hypertrophy, degenerative disc disease with disc bulges, and facet arthropathy. Of the 78 patients, 97% had concurrent foraminal stenosis. So when we broke that down to the patients who had the Streamlined Technique after Dr. Jassal was trained in proper performance of the technique, we had 44 “streamlined” patients and then 34 patients who had the Standard Approach for the mild® Procedure.

So we took the 44 patients with the Streamlined Technique and the 34 Standard Approach patients and compared occurrence of postoperative complications, including reoperation, device- and procedure-related AEs, serious AEs, and lumbar spine fractures. We also did include removal of hardware, although we do know a big pro of the mild® Procedure is that there is no hardware placed into the patient, really maximizing patient benefit and minimizing risks for patients. This study did show that the Streamlined Technique did not have any increase in risk for patients versus the Standard Approach.

Navdeep Jassal, MD (04:13):

So in conclusion with our study, the Streamlined Technique is a more minimally invasive procedural approach for the mild® Procedure and it’s even comparable in terms of safety profile to the Standard Technique or the Standard Approach. There’s really no increased risk of serious postoperative complications to the patients. And we know that it’s comparable to the data that was shown in the ENCORE study or the RCT in the past.

Also, the mild® Procedure should be considered first-line intervention for patients with lumbar spinal stenosis, with neurogenic claudication symptoms, in a state where they know that they have at least 2.5 millimeters of ligamentum flavum on an MRI exam or a CAT scan study. So really they should be considered first-line intervention after conservative therapy is tried and even after the first epidural steroid injection is completed for your patient.
