Treatment of benign esophageal tumors by endoscopic techniques.
Gastrointestinal endoscopy has changed in recent years from a largely diagnostic to a highly therapeutic procedure. Technical advances in endoscopic ultrasound as well as new devices designed for endoscopic mucosal resection (EMR) have opened the field to many therapeutic possibilities. Endoscopic resection is technically challenging, and while our colleagues in the Far East have been using such techniques for over a decade, EMR in the West is still in its infancy. The decision to resect a benign esophageal tumor must take several factors into account including whether the patient is symptomatic; characteristics of the particular tumor (including the potential for malignant transformation, risk of bleeding, and obstruction); and the available therapeutic options. Endoscopic resection of benign esophageal tumors is an attractive option as it is a safe and minimally invasive procedure. Its use is limited, however, to smaller tumors arising from the mucosal or submucosal layers. In this article we examine the techniques used in endoscopic mucosal resection and review the literature on this subject.
