Endoscopic Assisted Latissimus Dorsi Musculocutaneous Flap for Breast Reconstruction
Endoscopic Assisted Latissimus Dorsi Musculocutaneous Flap for Breast Reconstruction
This prospective single-arm case series evaluates the feasibility, safety, and clinical outcomes of endoscopic-assisted latissimus dorsi musculocutaneous flap harvest for breast reconstruction. The study includes women with post-oncologic or post-burn breast deformities requiring autologous tissue reconstruction with a skin paddle measuring 6 cm or less in its greatest dimension.
The primary objective is to assess the feasibility of minimally invasive flap harvest while preserving reconstructive effectiveness. Secondary outcomes include flap viability, operative time, postoperative pain, drain duration, donor-site morbidity, scar quality, complications, and patient satisfaction. Patients are followed for one year after surgery, with clinical assessment and patient-reported outcome measures used to evaluate reconstructive and aesthetic results.
The latissimus dorsi (LD) musculocutaneous flap is a well-established option for breast reconstruction because of its reliable vascular anatomy and versatility. However, conventional flap harvest requires a long dorsal incision that may result in visible scarring, postoperative pain, seroma formation, and donor-site morbidity. Endoscopic-assisted harvest has been developed to minimize donor-site scarring while preserving the advantages of the conventional technique. Although endoscopic harvest of the muscle-only flap has been increasingly reported, evidence regarding endoscopic-assisted harvest of the musculocutaneous latissimus dorsi flap remains limited because inclusion of a skin paddle presents additional technical challenges.
This prospective case series was conducted at Kasr Al Ainy Hospital, Cairo University, to evaluate the feasibility, safety, and clinical outcomes of endoscopic-assisted latissimus dorsi musculocutaneous flap harvest in women requiring breast reconstruction following breast cancer treatment or burn deformity. Eligible patients required autologous reconstruction using a musculocutaneous flap with a skin paddle measuring no more than 6 cm in its greatest dimension and had an intact latissimus dorsi muscle and thoracodorsal vascular pedicle.
All procedures were performed under general anesthesia using an endoscopic-assisted technique through a limited donor-site incision. The flap was harvested under endoscopic visualization while preserving the thoracodorsal vascular pedicle, followed by transfer of the flap to the breast defect. Standard postoperative management and follow-up were performed for one year.
Outcome measures include flap viability, operative time, postoperative pain, drain output and duration, donor-site and recipient-site complications, scar quality assessed using the Vancouver Scar Scale, and patient-reported satisfaction measured using the BREAST-Q questionnaire. The study aims to determine whether endoscopic-assisted harvest of the latissimus dorsi musculocutaneous flap provides reliable breast reconstruction with reduced donor-site morbidity and improved cosmetic outcomes compared with those historically reported for conventional open harvest.
