Donor-site morbidity of the segmental rectus abdominis muscle flap

The donor-site morbidity of the segmental rectus abdominis muscle flap was evaluated in 20 patients with an average follow-up time of 47 months. Our c riteria were based on static and dynamic functional results including relax ation and hernia of the abdominal wall, aesthetic outcome and patient satis faction. The dynamic functional tests of the abdominal wall showed good results corr esponding to the reported minimal impairment of quality of life. There was one abdominal hernia after wound infection and secondary healing. There was no evidence of abdominal wall instability in any of the other patients. Th e aesthetic outcome was excellent when a transverse lower abdominal incisio n, asymmetrically elongated to the donor site, was used and moderate in the case of a paramedian vertical incision. Ninety-five per cent of the patien ts were completely satisfied or satisfied with the result at the donor site . In the segmental use of the free rectus abdominis flap a high degree of sub jective patient satisfaction reflects the favourable outcome of our examina tions. On the other hand there is a clinically significant functional donor -site defect of this flap. As this procedure is still widely used, and as i ts indication is closely linked to its absolute and relative donor-site def ect, comparisons with the alternatives, e.g. the partial latissimus dorsi m uscle flap, the extended gracilis muscle flap or the serratus anterior musc le flap will have to be made.
