A Trial Compares Loop Drainage to Traditional Incision and Drainage:

Another clinical trial is providing strong evidence in favor of the “loop drain” method for abscess treatment as opposed to traditional incision and drainage. The article, “A Randomized Controlled Trial of Novel Loop Drainage Technique Versus Standard Incision and Drainage in the Treatment of Skin Abscesses”, based on a prospective randomized controlled trial with 217 subjects, concludes the following:

“The LOOP and packing techniques had similar failure rates for treatment of subcutaneous abscesses in adults, but the LOOP technique had significantly fewer failures in children. Overall, pain and patient satisfaction were significantly better in patients treated using the LOOP technique.”

A previous trial that Mar-Med featured (see link here), entitled “Loop Drainage Is Noninferior to Traditional Incision and Drainage of Cutaneous Abscesses in the Emergency Department”, also concluded evidence in favor of the loop drainage method:

“Our study provides evidence that LD is noninferior to I&D in achieving complete abscess resolution at 14 days and is associated with fewer return ED visits and fewer complications. This makes it an attractive alternative treatment option for abscesses.”

Mar-Med designed our Derma-Stent to improve upon the “loop drain” improvised method, where clinicians tie elastic materials into a loop through two holes of an abscess. Mar-Med’s Derma-Stent can be used in 1 or 2 incisions and does not require tying a knot to stay in place.

Changing clinical practice can be a lengthy process and requires convincing evidence. Many clinicians have adopted the loop drain method over traditional I&D believing it is more comfortable, efficacious and easier for the patient to self-manage. But data on this topic has been limited by small sample sizes and predominantly retrospective study designs. With the help of these recent trials more convincing evidence is now available.
