Effect of different fat purification methods on scar pain after breast surgery

  Objective  To treat scar-related pain with Autologous fat transplantation(AFG) through different methods of fat acquisition and fat purification, sum up the treatment experience of AFG in fat acquisition and purification.

  Methods  A total of 115 patients were randomly divided into treatment group (n=58) and control group (n=57), treatment group were further divided into groups A, B, C and D. The group A (n=16) received dry pumping and centrifugal method, the group B (n=13) received dry pumping and static method, the group C (n=14) received wet pumping and centrifugal method, and the group D (n=15) received wet pumping andstatic method. Patients in the control group(n=57) received no special treatment. The therapeutic effects of AFG in scar related pain were observed, the Visual Analog Scale (VAS) score before and after treatment and the satisfaction degree by survey after treatment were compared, and the therapeutic experience of AFG in fat acquisition and purification was summarized.

  Results  After treatment, VAS scores of groups A, B, C and D were lower than those before treatment and the control group (P < 0.001). The satisfaction scores of each group of the treatment group were higher than that of the control group (P < 0.001).

  Conclusion  AFG technique is effectivein scar pain after breast surgery. In the process of fat acquisition, injecting swelling fluid or not, centrifugal method or static method all have no influence on therapeutic effects.
