Participant Flow

First subject was consented 12Aug2009 and last subject final follow up visit 15May2011. 241 subjects were enrolled from 9 sites in the USA and Europe. Of those, 229 were consented, randomized and treated. All subjects were volunteers scheduled for individual or combined abdominoplasty, mastopexy or reduction mammaplasty.

Measure
V-loc and Monocryl
Each subject served as their own control and was randomized as to which side of the body received the test procedure. On the test closure side, the investigator could elect not to close the deep dermal layer, but if the deep dermal layer was closed, interrupted 3-0 Monocryl(TM) sutures were required to be placed no more than 5cm apart. Following optional closure of deep dermal layer, the intradermal layer was closed with running V-Loc(TM)90 or 180 device. The study was initiated with V-Loc(TM)180 as the only test device and V-Loc(TM)90 was added via protocol amendment 13Apr2010.

PRIMARY outcome

Timeframe: At time of surgery

Population: Includes only those subjects where a deep dermal layer was closed.

In calculating the total dermal closure time, only the intradermal closure time is used for those subjects that did not have the deep dermal layer closed.

V-Loc 180 / 90 Wound Closure Device
n=229 Participants
Each subject served as their own control and was randomized as to which side of the body received the test procedure. On the test closure side, the investigator could elect not to close the deep dermal layer, but if the deep dermal layer was closed, interrupted 3-0 Monocryl(TM) sutures were required to be placed no more than 5cm apart. Following optional closure of deep dermal layer, the intradermal layer was closed with running V-Loc(TM)90 or 180 device. The study was initiated with V-Loc(TM)180 as the only test device and V-Loc(TM)90 was added via protocol amendment 13Apr2010.
3-0 Monocryl Sutures
n=229 Participants
Each Subject served as their own control and was randomized to which side of the body received the control sutures. The control side included mandatory closure of the deep dermal layer with interrupted 3-0 Monocryl(TM)sutures, spaced no further than 2cm apart, followed by closure of the intradermal layer with running 3-0 Monocryl(TM) sutures.

SECONDARY outcome

Timeframe: 12 weeks

Population: Subjects who did not return for the 12 week follow-up visit were excluded from the analysis.

Photographs of scars were obtained at 12 week visit and reviewed by a independent blinded plastic surgeon. The blinded assessor scored four elements of scar appearance on a scale of 1 to 5 each, including color match, width, borders and edges, and contour and distortion. On this scale, 1 = worst, 2= poor, 3= average, 4=good and 5=excellent. For the purpose of analysis, all scores for a patient were summed into a single composite score (4-20).

Measure
V-Loc 180 / 90
n=229 participants at risk
Within-patient study. Each patient received either V-Loc 180 or 90 on one side and the control suture (3-0 Monocryl)on the other side.
Control - Monocryl 3-0
n=229 participants at risk
Within-patient study. Each patient received either V-Loc 180 or 90 on one side and the control suture (3-0 Monocryl)on the other side.
Midline
n=229 participants at risk
Within-patient study. Each patient received either V-Loc 180 or 90 on one side and the control suture (3-0 Monocryl)on the other side. Events in this group occurred at midline incision and therefore not assigned to a treatment arm.
Non-protocol Incision or Systemic Events
n=229 participants at risk
Within-patient study. Each patient received either V-Loc 180 or 90 on one side and the control suture (3-0 Monocryl)on the other side. Events in this group occurred at either a non-protocol incision or were systemic in nature.
