Umbilical transposition in TRAM flap: a simple horizontal translocation.

ABSTRACT

A simple method of umbilical repositioning by incising the anterior rectus sheath and rectus abdominis muscle is reported for cases of unilateral abdominal wall plication during the TRAM flap operation. This method keeps the umbilicus stable and nonstenotic, and it avoids hypertrophic scars, which result from other techniques such as direct suturing of the stalk to the skin. Although this method might weaken contralateral muscle activity, the patients we operated on maintained their ability to perform sit-ups, and no periumbilical weakening was noticed.
