The aim of this study is to evaluate the clinical benefits of using plasmakinetic cautery in abdominal free flap dissection for breast reconstruction. Methods: Forty women undergoing abdominal-based microsurgical breast reconstruction (DIEP/MS-TRAM) were randomized to plasmakinetic cautery (n=20) or conventional electrocautery (n=20) for dissection of the abdominal free flap. Total abdominal wound drainage volume/duration, operation time and complications such as seroma and haematoma were examined. Results: Age, body mass index, type of reconstruction and abdominal flap weight were similar in both groups. Mean abdominal drainage volume was (279±262) mL in conventional electrocautery group and (294±265) mL in plasmakinetic cautery group (P=0.853). Plasmakinetic cautery group mean drainage duration (4.3±2.2 days) was no difference compared to conventional diathermy group (3.8±2.0 days, P=0.501). Mean operation time in the conventional electrocautery group and plasmakinetic cautery group was 157±50 vs . 174±70 min respectively (P=0.195). There was more seroma detected in the conventional electrocautery group compared to plasmakinetic cautery group at days 7, 14 and 42 post-operation, but this was not statically significant. 2 haematomas in conventional diathermy group and 1 haematoms in the plasmakinetic cautery group required evacuation. Conclusions: This study demonstrates that there are no significant differences between the use of plasmakinetic cautery and conventional electrocautery for abdominal free flap dissection.
