Ultracision versus electrocautery in performing modified radical mastectomy and axillary lymph node dissection for breast cancer : a prospective randomized control trial . BACKGROUND Treatment for breast cancer has improved dramatically over the decades . Nevertheless , modified radical mastectomy with axillary dissection remains the standard treatment for most patients , especially those with big tumours . The conventional technology is to use diathermy to cut and coagulate blood vessels . The Ultracision dissector has been widely used in laparoscopic surgery and is documented to be safe and fast for cutting and coagulating tissue . The aim of this study is to compare ultracision to electrocautery , looking in terms of amount of post operative drainage , duration of drain days , seroma formation and other complications . METHODOLOGY This study was a prospective randomized control trial of modified radical mastectomy performed for breast cancer in Pusat Perubatan Universiti Kebangsaan Malaysia ( PPUKM ) between 1st June 2007 to 31st December 2008 . Patients were randomized in two groups : group A ( n = 20 ) underwent modified radical mastectomy using ultracision ( UC ) and group B ( n = 20 ) with the conventional electrocautery ( EC ) method . Main outcome measures were amount of drainage and duration of drain days . An unpaired 2-tailed Student 's t test and the χ2 test to compare the groups . RESULTS A total of 40 patients were involved in this study . The majority of patients were Malay ( 55 % ) followed by Chinese ( 35 % ) , Indian ( 5 % ) and others ( 5 % ) . The mean volume of drainage from the axilla in the EC group was significantly higher than UC group [ 489.5 versus 188.1 mls ( p < 0.001 ) ] . The mean volume of drainage from the breast and the total drainage from both the breast and axilla was also significantly higher in the EC group compared to UC [ 169.3 versus 58.8 mls ( p = 0.004 ) and 663.7 versus 247.0 mls ( p < 0.002 ) respectively ] . The drainage consequently showed significant reduction in terms of drain days in the axilla [ 6 days versus 3 days ( p < 0.002 ) ] and the breast [ 3 days versus 2 days ( p < 0.002 ) ] in the UC compared to the EC . There was no significant complication in both arms . In conclusion , the use of ultracision able to reduce the amount of drainage and the number of drain days after performing modified radical mastectomy . In doing so , the use of this technology enable us to discharge patients earlier without significant morbidities .
