Endoscopic submucosal dissection is a challenging technique that enables en-bloc resection for large colorectal tumors, as laterally spreading tumors, particularly difficult, if the ileocecal valve and terminal ileum is involved. Herein, we report on one of 4 cases. The procedures, using a bipolar needle knife (B-Knife) to reduce the perforation risk and carbon dioxide instead of conventional air insufflation for patient comfort, achieved curative resections without any complications.
内镜黏膜下剥离术是一种具有挑战性的技术,它能够为大肠侧向发育型肿瘤等大型结直肠肿瘤进行整块切除,如果涉及回盲瓣和末端回肠则尤其困难。本文报告了其中的 1 例。该手术采用双极针形切开刀(B-Knife)以降低穿孔风险,并用二氧化碳代替常规的空气注入以提高患者舒适度,在没有任何并发症的情况下实现了治愈性切除。
