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. There were no other complications observed except for 2 and 3 cases of subcutaneous congestion and local depression respectively. All patients were followed up for 3 to 56 months with regular ultrasound examination, and no local recurrence was observed. Conclusion: using the EnCor vacuum-assisted breast biopsy (VAB) system in the minimally invasive resection of large benign breast tumors, the lesions can be completely removed with smaller scars and few complications. The simplicity and effectiveness make it easy to popularize.
