阑尾黏液囊肿的肠镜及超声内镜诊断

Colonoscopic and endoscopic ultrasonography diagnosis of appendix mucocele

目的探讨阑尾黏液囊肿的肠镜与超声肠镜特征和临床意义。方法收集2008年1月至2015年3月间3所医疗机构肠镜及超声肠镜诊断的阑尾黏液囊肿患者，患者均行肠镜、超声肠镜检查，行外科手术治疗，并得到术后病理证实。回顾性分析患者的内镜及临床资料。结果共收集阑尾黏液囊肿患者22例，腔内病变隆起大小为0．6-4．5cm，平均（1．84±1．42）cm。内镜下表现为不同程度的阑尾开口部黏膜隆起，表面光滑，阑尾开口位于病变边缘呈新月形，过度充气阑尾腔无开放。超声内镜显示病变为囊壁光滑，囊内容物呈均匀略低回声8例，呈混杂不均匀等低回声14例。外科采用阑尾切除治疗11例，回盲部切除治疗11例。结论肠镜与超声肠镜在阑尾黏液囊肿诊断和治疗方面具有重要的临床应用价值。

Objective To investigate the features and clinical value of endoscopic ultrasonography and colonoscopy for appendix mucocele. Methods The patients with mucocele of appendix who were diagnosed by endoscopic uhrasonography and colonoscopy in three hospitals all underwent surgery from January 2008 to March 2015. Appendix mucocele in these patients was confirmed by postoperative pathology and clinical data were retrospectively analyzed. Results A total of 22 patients with appendix mucocele were analyzed retrospectively. The average size of intralumen mucocele was 1.84 ± 1.42 cm （0. 6-4. 5 cm）. The colonscopic finding of appendiceal mucocele showed submucosal protuberance at the appendiceal orifice with smooth surface. The appendiceal orifice was found at the edge of appendiceal mucocele. Endoscopic uhrasonogrphy showed low echo with smooth cyst wall in 8 patients, mixed equal echo and low echo in 14 cases. Appendicectomy was performed in 11 patients and resection of ileocecum in 11 others. Conclusion Endoscopic uhrasonography and colonoscopy are valuable for diagnosis and treatment in appendiceal mucocele.
