Lesions with extension into the AO are often challenging for EMR.
When the involvement is deep, surgery is usually the first recommendation, however
in some cases of deep involvement an endoscopic treatment can be performed.
We present the case of a lesion with deep extension into the AO resected by “underwater”
EMR (video).
UEMR was performed with a 15mm rounded snare.
To complete the resection of the deep component, suction of the water and the tissue
were performed.
Time of the procedure until specimen retrieval was 24 minutes. Patient was discharged
after 2 hours with no complications.Histology showed LGD adenoma.
