Abstract: 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 ultrasonography 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 ultrasonogrphy 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 ultrasonography and colonoscopy are valuable for diagnosis and treatment in appendiceal mucocele.
