摘要
目的 :探讨透明帽吸引法的适应证、操作技巧、诊治消化道扁平隆起病变的效果及安全性。方法 :粘膜下层注射肾上腺素盐水 ,使病灶明显隆起 ,镜端连接透明塑料帽 ,将病变组织吸入透明帽内 ,圈套器套取病变组织后高频电凝切除。切下组织全部收集送病理检查 ,术后定期随访。结果 :共切除 3 3个病灶 ,除 1例食管平滑肌瘤和 1例残胃Ⅱa +c型早期癌未完全切除外 ,另 3 1例均切除完全。全部病例未发生大出血或穿孔等严重并发症。内镜随访 1～ 12月 ,除前述的 1例残胃早期癌复发外 ,其余病例均未见复发。结论 :透明帽吸引法粘膜切除术对消化道扁平隆起病变是一种简便易行、适应证广、安全有效的切除方法 ,值得推广应用。
Purpose: Endoscopic mucosal resection(EMR) is increasingly used for the removal of small gastrointestinal tumors. Several different EMR procedures have been established. EMR using a transparent plastic cap is a new technique. We used the technique and evaluated its feasibility, efficacy and effectiveness. Methods: Epinephrine saline solution(1∶10 000) was locally injected into the submucosal layer under the target lesion to induced a protrusion of the tumor. The endoscopy tip was attached a transparent plastic cap. The lesion was sucked into the cap, snare closed slowly, and the lesion was extensively resected with high frequency cutting current. The resected tumor was withdrawn for the examination of histology. Results: A total of 33 lesions including esophageal, gastric, colonic and rectum tumors were resected. 31 lesions were resected completely and not recurrent were found after 1～12 months of follow up. One esophageal leiomyoma and one gastric Ⅱa+c early carcinoma can't be resected completely. Not serious complication (perforation or massive bleeding) occurred. Conclusion: The technique of EMR using a transparent plastic cap is a simple, safe and easy accessed procedure for the resecting small elevated lesions in every part of digestive tract.
