CASE STUDY

CONSULTANT

AND PROCEDURE

DR JASON DUNN –

CONSULTANT GASTROENTEROLOGIST

An 82-year-old woman presented with worsening heartburn

symptoms,with a past history of hypertension, atrial

brillation and osteoarthritis.An endoscopy performed

locally revealed a nodule arising in a segment of Barrett’s

Oesophagus. The biopsy demonstrated high grade dysplasia

and she was referred to Dr Jason Dunn for further evaluation.

The nodular area was characterised using Narrow Band Imaging,

an optical enhancement technique. The lesion was then removed

by EMR in one section and con rmed as high grade dysplasia,

but no invasive cancer. This was undertaken as a day case under

conscious sedation.

The remaining Barrett’s segment was then successfully treated

with RFA in two sessions, two months apart, also under sedation.

The patient had minimal chest discomfort after the rst session,

was treated with Paracetamol, and returned to normal eating after

48 hours. Six months after referral, the patient has no residual

Barrett’s Oesophagus on follow-up biopsy.
