A long-term follow up of the laparoscopically harvested free omental flap for breast reconstruction

Abstract

Background: There are different types of reconstruction after mastectomy and breast-conserving surgery. Autologous reconstructions are nowadays more often preferred over implant-based reconstructions for many reasons. A more natural looking breast with a durable long-term result is one of the advantages. The greater omentum is frequently used in the general field of reconstructive surgery but has not been widely adopted in breast surgery. This report is the first larger series of patients who underwent a breast reconstruction using the laparoscopically harvested omental free flap (LHOFF). The aim of this report is to provide information about indication, surgical technique, short- and long-term complications, and patient satisfaction with aesthetic outcomes and health-related quality of life (HR-QoL).

Methods: Patients underwent a breast reconstruction with the LHOFF from 2014 to 2021 in Máxima Medical Center, Veldhoven, the Netherlands. All patients underwent a diagnostic laparoscopy prior to the reconstruction to examine whether the volume of omentum was deemed sufficient. Outcome measures included the Breast-Q for HR-QoL, patient satisfaction, short- and long-term complications, and abdominal complaints related to the transplanted omentum. Surgical data were retrieved retrospectively.

Results: Twenty-six patients were included in this article. Patients were 40 to 71 years old with a mean BMI of 21.5 (range 17.0-25.0). Mean weight of the omental free flap was 228 g (range 112-395). Four out of 26 cases underwent surgery due to venous congestion. There was one case of flap failure due to venous thrombosis. Mean time of follow-up was 54 months (range 8-179). Secondary corrections include a nipple reconstruction (n = 11), lipofilling (n = 11), a contralateral breast reduction (n = 3) or a breast implant (n = 2). Patients reported improvement in HR-QoL and good satisfaction with aesthetic outcomes. No abdominal complications were reported during the follow-up period.

Conclusion: The LHOFF is an autologous breast reconstruction technique that results in a soft, small breast with natural ptosis and minimal donor site morbidities. Patients report satisfactory aesthetic outcomes and good quality of life. The main limitation of this technique is the limited amount of volume of the omentum and the possible need for secondary corrections. No abdominal complications were reported. In the future, larger prospective studies are required to support implementation of the LHOFF reconstruction on a broader scale.
