[Cancer of the rectum and sigmoid. Our experience].

The paper reports the Authors' experience during the period 1989-91 and refers to 80 operated cases of rectum-sigma cancer. Given that data reported in the literature affirm that the limit of oncological safety is 1.5-2 centimetres distal from the tumour, and owing to their use of mechanical staplers, the Authors were able to use the preferred anterior section followed by low or very low colo-rectal anastomosis in 96% of cases. Miles' technique for abdomino-perineal amputation was only resorted to in 4% of cases. Tumours parameters, short- and medium-term complications and the results of a short-term follow-up are all discussed. The Authors compare their experience with that of other researchers reported in the literature.
