Pullthrough operation with delayed anastomosis for rectal cancer.

The technique of pullthrough resection with delayed anastomosis for carcinoma of the rectum as performed at the Cleveland Clinic is described. A series of 84 cases of rectal cancer treated in this way is reported. The average tumour diameter was 4.5 cm, the average margin of resection was 4.1 cm and the average distance of the tumour from the anus was 7.6 cm, The incidence of necrosis of the pullthrough was 1.2 per cent. The overall 5-year survival was 63 per cent with 100 per cent, 57 per cent and 53 per cent for Dukes' A, B and C tumours respectively. The quality of bowel function following surgery is described in detail. It is felt that this procedure has an important place in sphincter conservation in carcinoma of the middle third of the rectum.
