结直肠侧向发育型肿瘤的诊疗研究进展

Advances in Diagnosis and Treatment of Colorectal Laterally Spreading Tumors

结直肠侧向发育型肿瘤是一类起源于大肠黏膜的表浅型肿瘤,这类病变通常直径大于10 mm,沿肠壁黏膜呈侧向扩展或环肠壁生长,很少垂直浸润生长,具有较高的发病率及癌变率。随着近年来内镜技术的更新及各种辅助技术的发展,结直肠侧向发育型肿瘤的漏诊率及癌变率也有效降低,本文就结直肠侧向发育型肿瘤的诊断及治疗研究进展作一综述。

Colorectal laterally spreading tumors are superficial tumors originating from the mucosa of intes-tine with high incidence and canceration rate. These lesions are usually defined as 10 mm or great-er in diameter, and extend laterally along the luminal wall or grow around the intestinal wall, with little vertical invasion. With the update of endoscopic technology and the development of various assistive technologies in recent years, the missed diagnosis rate and canceration rate of colorectal laterally spreading tumors have also been effectively reduced. This study reviews the research progress in diagnosis and treatment of colorectal laterally spreading tumors.
