Objective  To investigate the benefits and drawbacks of breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap for breast cancer and treatment experience of postoperative operation-related complications. Methods  A retrospective analysis was performed on clinical data of 26 female patients with breast cancer who met the selection criteria between September 2021 and March 2023 aging 48.7 years (range, 26-69 years). All tumors were unilateral, with 17 on the left side and 9 on the right side. The tumor size ranged from 1.0 to 7.0 cm, with an average of 2.7 cm. The pathological staging included T1 in 11 cases, T2 in 14 cases, and T3 in 1 case; N0 in 10 cases, N1 in 11 cases, N2 in 2 cases, and N3 in 3 cases; no distant metastasis (M0) occurred when first diagnosed. Among them, 10 cases underwent breast conserving surgery, and 16 cases underwent nipple-sparing mastectomy. All patients underwent breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap. The operation time, incision length, and postoperative drainage volume in 3 days were recorded. Breast-Q “Satisfaction with back” scale was conducted to evaluate patients’ satisfaction with back at 6 months after operation. Results  The operation time was 280-480 minutes (mean, 376.7 minutes), the incision length was 10-15 cm (mean, 12.2 cm), the postoperative drainage volume in 3 days was 500-1 600 mL (mean, 930.2 mL). There were 4 cases of postoperative seroma, 1 case of incision rupture, 1 case of paresthesia of the thoracic wall, and 1 case of edema of the ipsilateral upper limb. All patients were followed up 12-30 months (mean, 20.1 months). No latissimus dorsi muscle flap necrosis, latissimus dorsi muscle atrophy, or shoulder joint dysfunction occurred during follow-up; 2 patients had recurrence of lymph nodes in the ipsilateral axilla after operation, but no distant metastasis occurred. Breast-Q score at 6 months after operation was 64-100 (mean, 79.5). The average score was 78.6 (range, 64-100) in patients underwent nipple-sparing mastectomy and 81.0 (range, 78-100) in patients underwent breast conserving surgery. Conclusion  Breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap for breast cancer is proven to be a surgical approach with safety and cosmetic effects with mild postoperative operation-related complications and considerable patient satisfaction.
