Objective Transanal endoscopic microsurgery (TEM) is a safe and effective treatment for the excision of benign rectal adenomas. In recent years it has been used for the excision of malignant lesions, although its use in this context remains controversial. The aim of this study was to investigate the local recurrence of rectal cancers following local excision by TEM. Method Forty‐two patients with rectal cancer were treated by TEM between 1998 and 2005. However, six patients went on to have immediate radical surgery and are excluded from the study. Of the remaining 36 the treatment intention was for cure in 16 (38.1%), compromise in 17 patients unfit for radical surgery (40.5%), and palliation in three (7.1%). Results The mean age of patients was 75 years (range 41–90). The mean lesion area was 15 cm 2 (range 0.8–42) and mean distance from the dentate line was 6.6 cm (range 0–11). The mean follow up was 34 months (range 4–94). During the follow‐up period there have been eight local recurrences (22%). The recurrence rates were 26% (6/23) for pT1, 22% (2/9) for pT2 and 0% (0/4) for pT3 lesions. The mean time to recurrence was 18.3 months (range 5–42). Conclusion Transanal endoscopic microsurgery is a safe procedure with obvious advantages over radical procedures. However, in this study the local recurrence rate is high. The recurrence rate may be an acceptable compromise in elderly or medically unfit patients but is hard to justify for curative intent.
