- less time to close the incision as there is no tying
- multiple layers (subcutaneous and dermis) can be closed together with one continuous suture
- less suture "spitting" as no knots to be dissolved
- less or no strangulation of tissue as there are no knots tied
- no need for an assistant to "follow" the suture
QuillTM SRS contains bidirectionally oriented barbs to anchor tissues and does not require knots to approximate opposing edges of a wound. Tying of knots with QuillTM SRS will damage the barbs and potentially reduce their effectiveness. For the bidirectional forces to be created and for the device to function properly, both sides of the QuillTM SRS must be engaged in the tissue. Additionally, when completing placement, an additional J-stitch or bite of tissue lateral to the end of the incision is required to lock the device in place.Avoid contacting the QuillTM SRS with other materials (e.g. surgical gauze, drapes, etc.) in the surgical field to prevent ensnaring on the barbs. If the barbs catch, carefully pull the material in the opposite direction of the needle to disengage it from the barbs.When using QuillTM SRS subcutaneously, the device should be placed as deeply as possible in order to minimize erythema and induration normally associated with absorption.Care should be taken to avoid damage when handling. Avoid crushing or crimping the suture material with surgical instruments, such as needle holders and forceps. Do not pull the QuillTM SRS out of the package by the needles as this can cause the barbs to catch on one another. Do not attempt to remove memory in the polymer by running fingers down the suture material as this can damage the barbs.
I would think that some down sides to using barbed sutures might be:
- need to "never" redo a stitch placement as you can't "back" the suture out
- ability to "feel" the barb if placed to superficial
- can patient's "feel" the barb if to near the muscle layer?
