Endoscopic mucosal resection is a safe resection tool for selected flat, sessile and lateral spreading tumours of the colon. Transanal microsurgical resection of select rectal neoplastic lesions is another accepted modality. Recent data suggests transanal microsurgery may have high complication rates. We conducted a prospective clinicopathological evaluation of an extended endoscopic mucosal resection technique for highly selected lesions of the rectum and assessed outcome data over a maximal 24‐month period. Patients and methods Eighty‐three patients with known rectal neoplastic lesions underwent chromoscopic colonoscopy and on‐table staging using a high‐frequency (12.5 MHz) mini‐probe EUS by a single endoscopist. Patients with T2 or node positive disease were referred for surgery. Following extended endoscopic mucosal resection patients were followed‐up at 3, 6, 12 and 24 months post ‘index’ resection with chromoscopic endoscopy and EUS. Procedural complications, recurrence rates and outcome data were collected. Results Sixty‐two patients fulfilled inclusion criteria. Median procedure time was 48 mins (range32–126). Lateral spreading tumours (median diameter 30 mm; range 18–42 mm) and sessile lesions (median diameter 38 mm; range 25–86 mm) accounted for 19% and 81% of lesions, respectively. Ninety‐seven percent of patients undergoing EMR were discharged within 6‐h of procedure. Thirty‐day re‐admission and death rate was 0%. Bleeding complications occurred in 5/62 (8%) of patients with all achieving complete haemostasis using endo clips. None required transfusion. There were no procedural related complications or perforations. Overall ‘cure’ rate at a median follow‐up of 16 months was 98%. Conclusions Extended endoscopic mucosal resection for rectal neoplastic lesions can achieve superior results to those of per‐anal excision and trans‐anal microsurgery with regard to complications and recurrence rates. Extended endoscopic mucosal resection may be an alternative therapeutic modality in selected patients.
