Introduction There is limited experience of endoscopic submucosal dissection (ESD) for resection of colorectal lesions in the West and outcome data tends to be worse than that reported from Japanese centres. We report the outcomes of ESD in a single, tertiary UK referral centre. Methods A prospective database was analysed including 165 consecutive patients (mean age: 64.6±12.6 years, 62.4% males) with 173 colorectal neoplasms resected by ESD between 3/2012 and 12/2017. Two experienced colonoscopists performed all procedures. Results The median (IQR) lesion size was 3.5 cm (2–5), and 140 (80.9%) were located in the rectum. Overall, 49.7% were granular-type laterally spreading tumours (LST), 19.7% were non-granular LST, and 30.6% were polypoid lesions. In 29 (16.7%) cases a flexible endosurgical platform was used to assist ESD of complex rectal polyps [median(IQR) size: 6 cm (5–8)] by dynamic trans-anal retraction (Trans-Anal Submucosal Endoscopic Resection; TASER). Histology showed low-grade adenoma/dysplasia in 83 (47.9%), high-grade adenoma/dysplasia in 52 (30%), T1 cancer ( Conclusions The current study demonstrates favourable clinical outcomes of selected colorectal ESD in a Western endoscopy setting. Further studies addressing the cost-effectiveness of ESD and comparing its long-term outcome with endoscopic mucosal resection in the West are needed.
