Abstract
Endoscopic mucosal resection (EMR) is established as the primary approach for large/complex dysplastic lesions. However, submucosal fibrosis caused by previous attempts at removal, biopsy, inflammation, or tattoo can cause a benign "negative lift sign" and create difficulty for EMR. Here, we present the use of distal-cap assisted EMR (EMR-DC) specifically for the use of resecting dysplastic colon lesions when submucosal fibrosis is present in IBD patients. 16 IBD patients were retrospectively evaluated from two high volume centers. The patient demographics, lesion pathology and classification, outcomes including time and success of resection, SAEs within 30 days of the procedure, and efficacy were measured. 75% of patients treated with EMR-DC achieved complete resection with 0 serious adverse events within 30 days of the procedure. EMR-DC represents an attractive option for the resection of adherent dysplastic lesions in chronic IBD which is effective, safe, and inexpensive.
