RESUMO
ObjectiveTo investigate the clinical effect of the double stapling technique for anus-preserved (Dixon) and Miles procedure of rectal carcinoma. MethodsFifty-eight cases were divided into 29 cases as control group and 29 cases as observation group by digital table method. The distance of their carcinoma was 4-7 cm to anus. The control group was treated with Miles procedure of rectal carcinoma, the observation group was treated with double stapling technique for Dixon. ResultsThe operation time of observation group was ( 180 ± 56) min, the control group was (240 ± 73)min(P ＜ 0.05). Five-year survival rate of observation group was 77.9％, the control group was 79.3％ (P ＞0.05);the recurrence rate of observation group was 6.9％(2/29),the control group was 6.9％(2/29) (P ＞ 0.05). In the observation group,nobody suffered encopresis after 1 year,postoperative stool frequency was ≤5 times/d,while the control group occurred encopresis gradually. ConclusionIf the distance of carcinoma is 4-7 cm to anus, the way of the double stapling technique for Dixon can get the similar short term effect with the way of Miles, and can get more ability to control it.
