For one-piece resection the conventional technique of endoscopic mucosal resection (EMR) is limited to gastric mucosal tumors of 10 mm or less in size. In this retrospective study, we investigated the efficacy and complications associated with a new EMR method, using an insulated-tip diathermic knife (IT-EMR).
In a total of 41 patients gastric mucosal tumors were resected using IT-EMR.
One-piece resection rates were 82% (14/17) for lesions of 10 mm or less, 75% (12/16) for those between 11 and 20 mm, and 14% (1/7) for those of over 20 mm. Complication rates for severe bleeding and perforation were 22% and 5%, respectively. With a median follow-up period of 32 months, no recurrence was observed after these procedures.
Compared with conventional EMR, this new method may have significant benefits, particularly regarding one-piece resection of lesions between 11 and 20 mm in size, and may also have a lower recurrence rate.
对于整块切除，传统的内镜黏膜切除术（EMR）仅限于大小在10毫米及以下的胃黏膜肿瘤。在这项回顾性研究中，我们调查了一种使用绝缘头电刀（IT-EMR）的新型EMR方法的疗效及相关并发症。
共有41例患者的胃黏膜肿瘤采用IT-EMR进行切除。
10毫米及以下病变的整块切除率为82%（14/17），11至20毫米病变的整块切除率为75%（12/16），20毫米以上病变的整块切除率为14%（1/7）。严重出血和穿孔的并发症发生率分别为22%和5%。中位随访期为32个月，这些手术之后未观察到复发情况。
与传统EMR相比，这种新方法可能具有显著优势，尤其是对于11至20毫米大小病变的整块切除，并且复发率可能也更低。
