SUMMARY
Barrett’s esophagus (BE) is associated with an increased risk of
developing adenocarcinoma. Cancer development is preceded by dysplastic changes.
Management strategies for BE are based on a patient’s dysplasia status. Advances
in endoscopic treatment make early malignancies, for which surgical resection is
the only accepted therapy, amenable for minimally invasive endoscopic treatment.
Endoscopic mucosal resection (EMR) is a minimally invasive endoscopic technique
that can be used in patients with circumscribed mucosal carcinomas. The
technique is also useful as a diagnostic procedure by obtaining a full-thickness
mucosal specimen for histologic examination. Photodynamic therapy (PDT) using
the prodrug 5-aminolevulinic acid, is an ablative therapy that destroys the
esophageal mucosa leaving the deeper layers of the esophageal wall intact. Cell
damage is achieved by the action of light on the photosensitizing agent
protoporphyrin IX in the mucosa, with skin photosensitivity of less than 48
hours. Such mucosal ablation, however, can also be accomplished with more common
thermal techniques like Argon plasma coagulation (APC). In all these ablative
procedures, squamous regeneratin is obtained by rigorous antacid therapy.
In selected patients these endoscopic ablation methods, although still
experimental, might already offer an alternative to esophagectomy. The need for
further improvement in conjunction with the lack of long-term follow-up data,
however, limits the use of these techniques to expert centers.
