目的:探讨水下内镜下黏膜切除术(UEMR)治疗十二指肠平坦型病变的效果。方法:回顾性分析青岛大学附属医院消化内科收治的1例十二指肠降部平坦型息肉病例的临床、内镜特点及其内镜治疗结果。结果:60岁女性因常规查体行胃镜检查,白光内镜十二指肠降部见约10 × 8 mm低平隆起,NBI结合放大胃镜显示病变边界清晰,微血管及微结构欠规则。行UEMR完整切除病变,术后病理为管状腺瘤,无并发症发生。结论:UEMR操作简单,完整切除率高,术后并发症少,复发率低,可作为内镜下切除十二指肠平坦型病变简单、安全、有效的方法进行临床推广。Objective: To evaluate the therapeutic efficacy of underwater endoscopic mucosal resection (UEMR) in the management of duodenal flat lesions. Methods: We present a case study involving a patient with a flat polyp in the descending duodenum who was admitted to the Gastroenterology Department of the Affiliated Hospital of Qingdao University. A retrospective analysis was conducted to examine the patient’s clinical presentation, endoscopic characteristics, and outcomes following endoscopic treatment. Results: A 60-year-old woman underwent gastroscopy due to routine checkup, and about 10 × 8 mm low flat bulge was seen in the descending part of duodenum under white light endoscopy, and NBI combined with magnified gastroscopy showed that the lesion had clear boundaries, and microvessels and microstructures were under-regularized. UEMR was performed for complete resection of the lesion, and the postoperative pathology was tubular adenoma without complications. Conclusion: UEMR is simple to operate, with a high rate of complete resection, few postoperative complications, and a low recurrence rate, and can be clinically promoted as a simple, safe, and effective method for endoscopic resection of duodenal flat lesions.
