Clinical Experience of Small Incision-Assisted Encor System in Resection of Large Breast Tumors

1. Abstract
1.1. Objective: to investigate the application value of small incision-assisted EnCor vacuum-assisted breast biopsy (VAB) system under the guidance of ultrasound in minimally invasive resection of large benign breast tumors. Method: from November 2012 to July 2021, minimally invasive atherectomy with small incision-assisted ultrasound-guided EnCor system was conducted on 59 large benign breast tumors out of 51 cases. Among these resectioned tumors, there were 23 tumors with the largest diameter of 30-39mm, 17 tumors with 40-49mm, 10 tumors with 50-59mm, and 9 tumors with 60-100mm. Results: from November 2012 to July 2021, minimally invasive atherectomy with small incision-assisted ultrasound-guided EnCor system was conducted on 51 out of 59 cases with large benign breast tumors. Among these resectioned tumors, there were 23 tumors with the largest diameter of 30-39mm, 17 tumors with 40-49mm, 10 tumors with 50-59mm, and 9 tumors with 60-100mm.
