Summary
Background: Lymphatic stasis and seroma formation are common complications of axillary lymphadenectomy in breast cancer surgery. The investigators aim is to test the hypothesis that the use of an ultrasonic knife for axillary dissection reduces the total amount and duration of persistent drainage and length of hospital stay. Method: The investigators have conducted a randomized trial on 94 patients (1 male, 93 females, mean age 64.7 years) who presented to the investigators unit with operable breast carcinoma. Patients in group A (38 cases) were operated on using exclusively the ultrasonic knife. Patients in group B (56 cases) were operated on using the conventional diathermy knife.
