A considerable interest in autologous tissue breast reconstructions ha
s developed recently, especially since Food and Drug Administration (F
DA) experts have raised the polemic on silicone implants. Although suc
h enthusiasm for the transverse rectus abdominis musculocutaneous (TRA
M) flap is justified in what concerns the final cosmetic result of the
reconstructed breast, the risk of abdominal sequelae should be explai
ned to the patient. Abdominal scarring, parietal weakness, strength lo
ss, and back pain have been recorded in a series of pedicled TRAM flap
reconstructions performed at the Institut Gustave-Roussy before 1991.
Cosmetic results of the abdomen were tested by three independent judg
es on the photographs taken of 132 patients. The global appearance of
the abdomen was rated as ''natural'' in 70 percent of the patients. Th
e umbilical scar was unacceptable in 25 percent and very good or not v
isible in 21 percent. The lower abdominal scar was rated as ''not acce
ptable'' in 35 percent. Abdominal strength was tested among the 38 pat
ients who underwent both preoperative and postoperative muscular testi
ng, of whom 18 had single-pedicled and 20 had bipedicled TRAM flap rec
onstructions. In the first group, the physiotherapist observed an impa
irment of function of the upper portion of the rectus abdominis and of
the oblique muscle in almost 50 percent. In the second group, the sam
e muscles were more severely impaired (in 60 percent), as well as the
function of the lower portion of the rectus (in 15 percent). The perce
ntage of patients complaining of ''light back pain'' in the 6-month po
stoperative period was 55 percent in the single-pedicle group and 30 p
ercent in the double-pedicle group. However, 20 percent of the bipedic
led patients complained of ''severe'' back pain, while there was none
in the single-pedicled group. In conclusion, abdominal sequelae after
TRAM flap breast reconstruction should not be underestimated and const
itute,ne of the drawbacks of the technique when it is compared with re
construction with a prosthesis.
