Although most solid tumors are principally removed via single block resection without incising the mass, disruption of the lesion is unavoidable in traditional TUR. Furthermore, pathological diagnosis is often difficult due to heat-related denaturation of tissues in TUR. Although transurethral en-bloc resection is useful for judging tumor invasion, it is associated with a prolonged operative duration. We attempted to show the safety and usefulness of combined endoscopic mucosal resection (EMR) and en-bloc resection in NMIBC patients. Methods: We investigated 39 patients with clinical NMIBC who were treated using our original EMR?+?en-bloc resection technique, which involved removal of the tumor mass that protruded from the mucosa, using a polypectomy snare similar to that used for EMR. The residual lesion was removed using en-bloc resection. The operative period, duration of hospitalization, and recurrence rates were compared with those of conventional TUR (n?=?31). Results: The mean (standard deviation, range) time interval for EMR and total operative duration were 1.6 (1.1, 1?5) min and 18.3 (10.5, 3?48) min, respectively. The total operative duration was comparable to that of TUR (17.3?min, p?=?0.691). The mean duration of catheterization in the EMR?+?en-bloc resection group (4.2?days) was also similar to that in the TUR group (3.7?days; p?=?0.285). No severe complications were observed with EMR?+?en-bloc resection. The pathologists were able to determine tumor invasiveness with considerable certainty in all specimens obtained via the EMR?+?en-bloc procedure than via TUR, and the difference in the ease of diagnosis was statistically significant (p?=?0.016). Recurrence rates were comparable (p?=?0.662) between the EMR?+?en-bloc (15.4%) and TUR groups (19.4%). Conclusions: Our results demonstrated that the EMR?+?en-bloc resection technique is feasible, safe, and useful for treating patients with NMIBC. Furthermore, this technique helps provide a more accurate pathological diagnosis.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"BMC Urology, 19(1), art.no.56; 2019","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"BioMed Central Ltd."}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1186/s12894-019-0486-0","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2019 The Author(s).
