Partial breast reconstruction for an inferomedial breast carcinoma using an omental flap

Various oncoplastic techniques are used for partial reconstruction after breast-conserving surgery (BCS), but treatment of an inferomedial breast carcinoma (IMBC) can be difficult, especially in a small breast. We review our experience with immediate partial breast reconstruction after BCS for an IMBC using a laparoscopically harvested omental flap (OF).

The subjects were 24 patients with an IMBC who underwent immediate partial breast reconstruction with the OF between April 2002 and June 2009. A wide excision (>20% of the breast tissue) was performed through a skin incision along the medial inframammary fold. The pedicled OF was harvested laparoscopically and used to fill the dead space in the inferomedial quadrant.

The mean follow-up period was 35 months. The mean tumor size was 3.2 cm. The mean volume of resected breast tissue was 180 g and the mean extent of resection was 40%. The complication rate was 12.5% and all were minor and treated conservatively. Laparoscopy-associated complications did not occur, except for one minor injury of the gastroepiploic artery. The surgical margin was positive in only 1 patient (4.2%) and neither local nor systemic recurrence has occurred to date in any patients. Cosmetic outcomes were mostly satisfactory, with minimal donor-site scars in the abdominal wall. Cosmetic failure occurred in 1 patient (4.2%) due to an inadequate OF volume.

Laparoscopic harvesting of the OF is a safe procedure with minimal donor-site morbidities and deformities. This approach is an option for immediate partial reconstruction after BCS for an IMBC.
