This article explores some of the innovations that already have been incorporated into endoscopes as well as imagines the kinds of advances that could transform endoscopes from passive tools into more active participants. It will be up to the planners and engineers and ultimately the marketplace to determine what is not only achievable but also useful.
BACKGROUND: En bloc EMR is performed in Japan as a curative treatment for early stage gastric cancer. However, current methods of EMR are technically difficult and require proficiency in determining the extent of the cancer. This study assessed the feasibility of a new method to obviate these problems and to facilitate en bloc EMR. METHODS: The new method uses two types of endoscopes: a magnifying endoscope with a narrow band imaging system to enhance the definition of mucosal and microcirculatory structure, and an endoscope with multibending tip deflection to maintain orientation during EMR. Forty-two consecutive cases of mucosal gastric cancer treated by EMR were reviewed retrospectively. In 12 of these patients, 12 lesions that fulfilled guideline criteria for EMR were treated by the modified, en bloc EMR method of circumferential incision and snare resection by using the two endoscopes. RESULTS: The rate of complete en bloc resection with the new method of EMR was 91.7%, (11/12). There was no major complication. CONCLUSIONS: The new en bloc resection method for EMR with two endoscopes described here is feasible and may be a safe and a reliable technique for curative treatment of mucosal gastric cancer.
