Persistent pain after colonic endoscopic mucosal resection : predictors, a management algorithm and outcomes

Introduction: Endoscopic mucosal resection (EMR) of large (_20 mm) laterally spreading colonic lesions (LSL) is safe, effective and superior to surgery. The advantage is based on a day stay model of care however the most common adverse event is abdominal pain and this is a major impediment to its efficiency. No prospective data exist on the optimal selection of analgesics, necessary recovery period or triggers that should alert the practitioner to a more serious trajectory and the need for escalation of care.
