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。
OBJECTIVE: To investigate the indications, operation skills and the effect and safety of the transparent cap-inducing method in the diagnosis and treatment of flat elevated lesions of the digestive tract. Methods: Adrenalin saline was injected into the submucosa to make the lesions bulge obviously. A transparent plastic cap was attached to the mirror end and the diseased tissue was aspirated into the transparent cap. All the tissues were collected and sent for pathological examination, followed up regularly. Results: A total of 3 3 lesions were resected, except for 1 case of esophageal leiomyoma and 1 case of residual gastric cancer Ⅱa + c. The other 31 cases were completely resected. No major bleeding or perforation and other serious complications in all cases. Endoscopic follow-up from January to December, in addition to the aforementioned 1 cases of residual gastric cancer recurrence, the rest of the cases were no recurrence. Conclusions: Transparent cap suction mucosal resection is a simple, feasible and safe method for removal of flat elevated digestive tract lesions. It is worth popularizing and applying.
