Prognosis and Inlfuencing Factor of Hematoma Complicated from Ultrasonography-guided EnCor Vacuum-assisted Breast Biopsy System in Minimally Invasive Surgery for Breast Lesions / 中国医学影像学杂志

ABSTRACT

Purpose To investigate the prognosis and influencing factor of hematoma complicated from ultrasonography-guided EnCor vacuum-assisted breast biopsy system in minimally invasive surgery for breast lesions, and to provide reference for clinical treatment. Materials and Methods 280 female patients with 486 benign breast lesions underwent minimally invasive excision using a ultrasonography-guided EnCor vacuum-assisted device, occurrence and the inlfuence factors of hematoma complicated from the operation was observed. Results All the 486 lesions were completely excised with EnCor system, hematoma (≥1cm) were found in 47 cases after 24 hours and almost disappeared in 6 months. After analysis of the occurrence of hematoma, it was found that the following situations would lead to a higher incidence of hematoma, which included lumps ≥ 2.5 cm, more than two lesions removed at one time, lumps locating deep inside the areola or the edge of breasts, bigger and less dense breasts, operation in menstrual period, pressure bandaging after operation less than 12 hours and operation without using adrenaline (P<0.05 or P<0.01). Conclusion Benign lesions breast can be effectively excised using ultrasonography-guided EnCor vacuum device, and the factors listed below could affect the occurance of hematoma complicated from the surgery, including the size, location and number of the resected nodules, breast shape, surgery during menstrual period, postoperative pressure bandaging and the use of hemostatics.
