Objective:To investigate the clinical value of new type (curved shears with pistol/scissor handle and hand control) ultrasonically activated scalpel (UAS) in radical resection of gastric carcinoma. Methods:Forty-nine cases undergoing radical resection of gastric carcinoma during April.2006 to March 2007 in the Department of General Surgery of Zhongshan Hospital of Fudan University were enrolled and their clinical data were analyzed．They were divided into two groups randomly before operation:26 cases in ultrasonically activated scalpel (UAS) group and 23 cases in conventional procedure group．Blood loss volume,operating time in lymphadenectomy，drainage volume of first 72 hours after operation,and the number of lymph node retrieval were recorded and compared between two groups. Results:Operating time，blood loss volume,drainage volume of first 72 hours in UAS group were significantly less than those in the conventional procedure group．However the number of lymph node retrieved had no obvious difference between the two groups. Conclusion:Using new type UAS in lymphadenectomy of gastric carcinoma radical resection is a safe and effective surgery procedure,and the new method has its superiority according to radical resection principle of malignant tumor．
