The most effective dissection technique for raising the flap in abdominoplasty is still controversial, particularly in high-risk massive-weight-loss patients. LigaSure ImpactPatients underwent primary abdominoplasty after massive weight loss at a single center from 1 January 2008 to 31 May 2015 and were retrospectively reviewed. A total of 94 patients eligible for the study were divided into two groups on basis of the dissection technique: LigaSure Impact group (29 patients) and the conventional technique group (65 patients). Total intraoperative blood loss was the primary endpoint. Duration of the operation, perioperative complications and re-operation were recorded as secondary endpoints.Baseline characteristics were well balanced between the groups. Significant differences were found in intraoperative blood loss favoring LigaSure Impact group (259.6 ± 198.8 mL vs 377.9 ± 190.0 mL, p = 0.004) and blood transfusion rates (13.8% vs 35.4%, p = 0.047). In contrast, operative time was significantly longer in LigaSure Impact group (168.6 ± 121.2 vs 179.7 ± 57.6 min, p = 0.005), while a tendency to shorter hospital stay was found in LigaSure Impact group (3.6 ± 1.1 days vs 4.6 ± 3.2 days, p = 0.081). Overall complications occurrence, Clavien-Dindo grade II (24.1% vs 55.4%) and grade III (13.8% vs 30.8%) complications were significantly lower in LigaSure Impact group (respectively, p = 0.005, p = 0.007, p = 0.016). Late (30 days) re-operation rate was significantly lower in the LigaSure Impact group (6.9% vs 27.70%, p = 0.0028). Specific wound complications showed no significant difference.LigaSure Impact vessel-sealing system may be beneficial in improving abdominoplasty outcomes in massive-weight-loss patients because it might reduce blood loss, need for transfusions, complications, and re-operations. |
