Abstract
Endoscopic transanal resection (ETAR) of rectal tumours is a simple and inexpensive procedure, well tolerated in elderly patients or those undergoing palliation. We have performed 137 ETARs in 81 patients with a 30-day mortality rate of 11·1 per cent and a postoperative complication rate of 15·3 per cent. Thirty-one patients (38 per cent) had ETAR for palliation: in this group rectal bleeding was abolished or improved in 66 per cent of patients, altered bowel habit (diarrhoea) corrected in 77 per cent of patients, faecal incontinence improved in 50 per cent of patients and rectal pain (including tenesmus) improved in 50 per cent of patients. Twenty-three patients (28 per cent) were treated for large benign rectal polyps: in this group symptoms were universally abolished. The technique is particularly suited to the management of these patients. Twenty-seven elderly patients with theoretically ‘curable’ rectal cancer underwent ETAR with a 78 per cent crude survival rate at 1 year. While long-term results remain to be assessed, ETAR appears a useful technique for treating selected patients with rectal tumours.
