Abstract
Aims: to evaluate the results of an endoscopic follow-up assistance protocol for colorectal cancer (CRC) after curative surgery.

Patients and methods: between 1994 and 1996, 205 patients with CRC were submitted to curative surgery in our hospital.
An endoscopic follow-up was proposed to the patients based on an endoscopy six months following surgery, in the case they did not have a complete endoscopy prior to surgery, or one year
after surgery if they did, another one two years later, and a third endoscopy between the third and fifth year. We retrospectively analyzed the follow-up outcome and endoscopic findings.
Results: 155 patients were submitted to follow-up, of which 74,2% completed the protocol. Three synchronous tumours, 4 anastomosis relapses and 2 metachronous tumours were detected.
Curative surgery was performed on 100% of the synchronous tumours, 50% of the relapses and 50% of the metachronous tumours. 48.3 and 20.6% of the patients had synchronous and
metacrhonous polyps, respectively. 14.7% of the polyps were larger than 1 cm, 21.7 and 4.8% were tubulovillous and villous, respectively,
and 3.7% had severe dysplasia. Finally, patients with synchronous polyps had higher risk of developing metachronous polyps (RR 7.1, CI 95% 2.3; 22.2, p< 0.0001).
Conclusions: the rate of adenomatous polyps with high risk
of malignant degeneration, metachronous tumours or relapses detected
by colonoscopy is low in our series. On the other hand, the
detection of polyps during follow-up was related to the presence
of synchronous polyps.
