中文摘要：

目的探讨胃部纤维钙化性肿瘤的内镜诊疗价值。方法回顾性分析4例内镜下治疗的胃部纤维钙化性肿瘤患者的病例资料，总结内镜治疗情况、并发症发生情况以及随访结果。结果4例患者共4处病灶，位于胃体3例、胃窦1例，术前内镜超声提示均起源于固有肌层，最大直径1．0—2．5em。2例向腔内生长为主的行内镜黏膜下挖除术（ESE）治疗，2例向腔外生长为主的行内镜全层切除术（EFR）治疗。4处病灶均整块完整切除，手术时间12—120min，中位时间62．5min，无一例严重并发症发生，术后病理均证实为纤维钙化性肿瘤。随访21—34个月，胃镜复查未见复发病例。结论内镜下行ESE和EFR治疗来源于胃部固有肌层的纤维钙化性肿瘤是安全和有效的，并可提供完整的病理学诊断资料，为胃部纤维钙化性肿瘤的诊疗提供了新的选择。

英文摘要：

Objective To study the value of the endoscopic treatment for the gastric calcifying fi- brous tumor. Methods From April 2010 to May 2011,4 patients with gastric calcifying fibrous tumor were treated with endoscopic treatment in endoscopy center of Zhongshan hospital. Effects and safety were then e- valuated. Results In 4 cases, diameter was 1.0-2. 5 era. AU the cases originated from the muscularis prop- ria. Two cases, which grew mainly in the lumen, were treated by ESE ; and other two cases, which grew out- side the cavity, were treated by EFR. No serious complication occurred during or after the ESE/EFR proce- dure （median, 62.5 min; range 12-120 min）. A definite diagnosis was confirmed by the postoperative pa- thology. No recurrence was found during the follow-up （median, 27 months; range 21-34 months）. Conclusion ESE/EFR appears to be a safe, feasible, and effective procedure for providing accurate his- topathologie evaluations and curative treatments for the gastric calcifying fibrous tumor originating from the museularis propria layer.
