Endoscopic Submucocal Dissection (ESD)

Picture
Endoscopic submucosal dissection (ESD) is a technique pioneered in Japan in the early 1990s for the resection of early gastric cancers en block regardless of size. Since then, its use has expanded to pharyngeal, esophageal, duodenal and colorectal lesions. Currently in North America, the technique for removing large superficial lesions in the GI tract is primarily limited to endoscopic mucosal resection (EMR). The main drawbacks of EMR is that these lesions are removed in multiple pieces which can limit the accuracy of pathological assessment and increases risk of recurrence. Contrary to EMR, the performance of an ESD allows for an en bloc (one complete piece) resection. This facilitates accurate pathological assessment and has the lowest risk of recurrence.

Unfortunately, the main deterrent in the performance of ESD in Canada is its technical complexity, lack of clinical experience and standardized training domestically.
