目的 探讨十二指肠乳头内镜下切除术（EP）治疗十二指肠乳头腺瘤（AA）的临床应用价值.方法 回顾分析长海医院消化内镜中心EP治疗AA成功率、并发症发生率、术后残留率及局部复发率等.结果 2005年7月至2009年7月EP治疗经内镜及病理确诊的从19例：散发AA18例（94.7%）,其中十二指肠多发腺瘤合并AA 1例;家族性腺瘤性息肉病并AA 1例（5.3%）.EP治疗一次性整块切除11例（57.9%）,分片切除8例（42.1%）.平均随访24.5个月（7～48个月）,首次EP后残留4例（21.1%）,EP治疗成功率为89.5%（17/19）.近期并发症：出血3例,轻症急性胰腺炎3例,急性胆管炎2例;远期并发症：胆管下端开口狭窄合并急性胆管炎1例,长期胆管支架置入后合并胆总管多发结石及急性胆管炎各1例.未发生穿孔等严重并发症以及EP术中转手术或死亡.结论 EP是治疗AA及其早期癌变的一种安全、有效的方法.

Endoscopic papillectomy for ampullary adenomas

Objective To evaluate the endoscopic papillectomy (EP) for ampullary adenoma (AA). Methods The resection rate, complications, local residual rate and local recurrence of EP for AA at endoscopy center of Changhai Hospital were retrospectively reviewed. Results From July 2005 to July 2009, a total of 19 patients with endoscopically diagnosed and pathologically confirmed AA underwent EP, in which 18 cases were scattered AA (94. 7%) including 1 case of multiple adenomas in duodenum, and 1 (5.3%) was familial adenomatous polyposis (FAP). The lesion was resected en bloc in 11 cases (57.9%) , and piecemeal in 8 (42. 1%). All patients were followed up at a mean period of 24. 5 months (range 7-48 months). The residual rate after first EP was 21. 1% (4/19), and the total success rate was 89.5% (17/19). Short-term complications after EP included 3 cases of bleeding, 3 cases of mild acute pancreatitis and 2 cases of acute cholangitis. Long-term complications were 1 case of stenosis of the common bile duct (CBD) orifice accompanied with acute cholangitis, 1 case of CBD stone and 1 case of acute cholangitis after stent placement. No such severe complications as perforation or procedure-related death was observed.Conclusion EP is a safe and effective modality for ampullary adenoma.
