The excision of right hemicolonic carcinoma with anterograde clearance to lymph nodes

To investigate the essentials of operation and the postoperative effect of right hemicolonic carcinoma with anterograde clearance of lymph nodes. One hundred and thirty-five patients with right hemicolonic infiltrated carcinoma, who were eligible for radical excision (D(3)), were divided into 2 groups. Among them, the anterograde clearance of lymph nodes was performed on 56 cases; the retrograde clearance was performed on 79 cases. Both groups showed no significant difference in age, sex, Dukes' staging and pathological type. The average time of operation: the anterograde group was (180 +/- 40) min; the retrograde group was (180 +/- 20) min. The average amount of bleeding: the anterograde group was (200 +/- 80) ml; the retrograde group was (200 +/- 30) ml. The cleared number of lymph nodes: the anterograde group were 6.3 +/- 4.2, 2.6 +/- 3.1, 1.5 +/- 2.3 in paracolon, middle and radicel of vasorum respectively, the total number was 11.4 +/- 8.6; the retrograde group were 6.4 +/- 2.2, 2.8 +/- 2.1, 1.1 +/- 1.1
