Up to 30% of women suffer from some benign breast diseases. It is a group of breast diseases which is troublesome to the patient but is not cancer. 1-3 Fibroadenoma, fibrocystic change, breast cysts, and breast ab- scesses account for most of these benign lesions. Triple assessment, which includes clinical examination, imaging, and histopathology, is the main method of approach in the diagnosis of these benign breast diseases. 5,6 Surgical excision is the definitive procedure performed for symp- tomatic benign breast tumors to alleviate anxiety regarding potential for growth or malignancy as well as physical discomfort. 7 Given the nonmalignant nature of these benign breast lesions, an important goal in treatment should be cosmesis. Currently, the accepted definitive treatment of surgical excision results in scar for- mation and potential for keloids, as well as breast volume loss and potential for nipple- areolar distortion or displacement. 8 The new minimally invasive techniques has advanced due to its appeal of low morbidity, early resumption of normal routine with promising outcomes and cosmesis.

An important goal in its treatment should be cosmesis, so a new minimally invasive technique has advanced. One of these techniques is the transaxillary endo- scopic resection. The aim of this study was to assess the feasibility, safety, operative time, postoperative pain, hospital stay, and cosmetic outcome of this transaxillary approach. Methods: This study was carried out on 40 female patients presented with benign breast tumors in the surgical oncology unit at the General Surgery Department, Tanta University Hospital during the period from January 2018 to January 2019. The patients included in the study aged ≥18 years, had solitary or multiple benign breast tumors, located at any breast quadrant. The patients subjected to transaxillary endo- scopic excision of the tumors. Results: The age of the patients ranged from 20 to 49 years with a mean age of 32 years. 60% of the lesions located in the upper half of the breast. Fibroadenoma was the most common finding in 80% of the patients, 60% of the patients had solitary tumor. The operative time ranged from 42 to 105 minutes with a mean of 61.4 min- utes. 88.8% of the patients considered the cosmetic outcome excellent. Conclusion: Endoscopic transaxillary excision of benign breast tumors is safe, feasi- ble and has excellent cosmetic outcomes with high patient's satisfaction.
