Brief summary
Endoscopic mucosal resection (EMR) of large (=20 mm) laterally spreading colonic lesions
(LSL) is safe, effective and superior to surgery. This 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 this efficiency. No prospective data exist on the optimal selection of
analgesics, the necessary recovery period or the triggers that should alert the practitioner
to a more serious trajectory and the need for escalation of care.

We aimed to characterise potential predictors for persistent (>5 minutes) post-procedural
pain (PP) and develop a simple and effective management algorithm for patients with PP based
on the need for analgesics in recovery.

Data on consecutive patients with a LSL referred for EMR at a single, tertiary referral
centre were included. Patient and lesion characteristics and peri-procedural data were
prospectively collected. Standard post EMR care included 2 hours in first stage recovery
followed by 1 hour in 2nd stage recovery where clear fluids were given and discharge after if
the patients were well. PP was graded from 0 to 10 using a Visual Analogue Scale (VAS). If PP
occurred >5 minutes, 1 gram of paracetamol was administered parenterally and outcomes were
monitored. If pain settled the patient was transferred to second stage recovery after medical
review. PP >30 minutes lead to clinical review and upgrade of analgesics to fentanyl, with a
starting dose of 25 micrograms (mcg) up to a maximum of 100 mcg. Investigations, admission
and interventions for PP are recorded.
