METHODS: A retrospective analysis was performed of Paris IIa colonic lesions resected utilising a C-EMR technique over a 3.5 year period at our center.
RESULTS: C-EMR was performed for 242 lesions in 151 patients. Lesion size ranged between 10mm to 50mm, with median size of 20mm. Ninety-five polyps were adenomatous, with 147 sessile serrated lesions (SSLs). At six month surveillance colonoscopy, the combined recurrence rate was 6.2%. Adenomas ≥20mm demonstrated a higher rate of recurrence (16.1%) compared to large SSLs (4.1%), medium adenomas (3.0%), and medium SSLs (1.4%). There were no adverse events reported following C-EMR.
CONCLUSIONS: C-EMR seems to be less effective for the resection of large adenomas when compared to medium adenomas or large SSLs. C-EMR is equally safe for all lesion size and histology.
方法:在我们中心3.5年期间,对采用C-EMR技术切除的ParisIIa结肠病变进行了回顾性分析。
结果:对151例患者的242个病灶进行了C-EMR。病变大小在10mm到50mm之间,中值尺寸为20mm。95个息肉是腺瘤,147个无柄锯齿状病变(SSLs)。在六个月的结肠镜检查时,合并复发率为6.2%.与大SSLs(4.1%)相比,≥20mm的腺瘤显示出更高的复发率(16.1%),中度腺瘤(3.0%),和中等SSL(1.4%)。C-EMR后未报告不良事件。
结论:与中型腺瘤或大型SSLs相比,C-EMR似乎对大型腺瘤的切除效果较差。C-EMR对于所有病变大小和组织学同样安全。
