Background: The donor site of abdominal flaps for breast reconstruction consists of a wide suprafascial cavity that poses a risk of seroma formation. The authors evaluated the efficacy of continuous progressive tension sutures (PTS) using unidirectional barbed absorbable sutures for decreasing the volume of fluid collection and the risk of seroma at the abdominal donor site.
Methods: Between March 2013 and February 2015, 37 consecutive patients underwent breast reconstruction using a deep inferior epigastric artery perforator flap. Two patients who underwent salvage operations were excluded. Ten patients underwent standard abdominal flap donor site closure without PTS. Seven received donor site closure with interrupted Vicryl PTS between the abdominal flap and abdominal muscle fascia. Eighteen patients underwent closure with continuous PTS using unilateral barbed absorbable sutures. Body mass index, the approximate flap area, the duration of drain maintenance, the total drained volume, and the incidence of seroma were compared across these 3 groups. The operative time and subjective difficulty perceived by the surgeon was compared between the 2 PTS groups.
Results: The total drained volume was lower and the duration of drain maintenance was shorter in both PTS groups than in the standard closure group. There were no cases of seroma in the PTS groups, and 2 that resolved with conservative care in the standard closure group. More time was required and the subjective difficulty score was significantly higher for interrupted PTS than for continuous PTS.
Conclusions: Continuous PTS effectively reduced the duration of drain insertion, the total volume of drained fluid, and was swifter and easier to perform than interrupted PTS.
