	ABSTRACT: Laparoscopic harvested omentum flap in partial breast reconstruction Indication of breast-conserving surgery (BCS) has been increased due to various oncoplastic techniques. Generally, volume replacement technique is needed when the breast size is small or the resection volume is large. The medial quadrants are usually difficult for the autologous flap such as TDAP or ICAP flap to replace; however, it is an elated field for the omental flap (OF) because of its anatomical advantage. For the tumors in the lower quadrants, an inframammary fold incision (IMI) is preferred both for tumor excision and extraction of the OF. A pedicled OF can be complexly harvested laparoscopically. The right gastroepiploic artery and vein are preserved as a pedicle. A subcutaneous tunnel is created from the IMF incision towards the xyphoid process to communicate with the abdominal cavity. The pedicled OF is carefully pulled out. The OF is very good option for endoscopic breast surgery. Because the OF is very soft and pliable, it is very easy to fill the irregular shaped partial mastectomy defect through a small incision for endoscopy. The flap can freely change its shape without any difficulty. Fixation of the OF to the chest wall is unnecessary when residual breast tissue is well fixed with the original position on the pectoralis major muscle. There is a limit to the adaptable volume and careful patient selection is mandatory, but the OF is an attractive option in partial breast reconstruction after endoscopic performed BCS, especially for the medial and inferior quadrants.

Laparoscopic harvested omentum flap in partial breast reconstruction

Indication of breast-conserving surgery (BCS) has been increased due to various oncoplastic techniques. Generally, volume replacement technique is needed when the breast size is small or the resection volume is large. The medial quadrants are usually difficult for the autologous flap such as TDAP or ICAP flap to replace; however, it is an elated field for the omental flap (OF) because of its anatomical advantage.

For the tumors in the lower quadrants, an inframammary fold incision (IMI) is preferred both for tumor excision and extraction of the OF. A pedicled OF can be complexly harvested laparoscopically. The right gastroepiploic artery and vein are preserved as a pedicle. A subcutaneous tunnel is created from the IMF incision towards the xyphoid process to communicate with the abdominal cavity. The pedicled OF is carefully pulled out.

The OF is very good option for endoscopic breast surgery. Because the OF is very soft and pliable, it is very easy to fill the irregular shaped partial mastectomy defect through a small incision for endoscopy. The flap can freely change its shape without any difficulty. Fixation of the OF to the chest wall is unnecessary when residual breast tissue is well fixed with the original position on the pectoralis major muscle.

There is a limit to the adaptable volume and careful patient selection is mandatory, but the OF is an attractive option in partial breast reconstruction after endoscopic performed BCS, especially for the medial and inferior quadrants.
