经胃镜保留浆膜层切除上消化道固有肌层起源肿瘤技术初探

目的 探讨经内镜浆膜下肿瘤切除术（ESSD）对上消化道黏膜下肿瘤切除的安全性及有效性。方法 收集2016年10月至2017年2月在南京鼓楼医院接受ESSD的6例黏膜下肿瘤患者资料，分析手术时间、手术成功率、术后病理、并发症等。结果 纳入的6例患者均完整切除肿瘤，其中1例患者发生浆膜面穿孔。肿瘤平均大小（27.5±10.0）mm，手术平均耗时（49±18）min。术后病理均提示为低危险度间质瘤。6例患者均顺利出院，未发生严重并发症。结论 ESSD作为一种新兴的内镜下治疗方法，对固有肌层起源肿瘤安全可靠。

Value of endoscopic resection technique of serous preservation for upper gastrointestinal tumor originated from muscularis propria

Objective To investigate the safety and efficacy of endoscopic subserosal dissection (ESSD) for patients with upper gastrointestinal submucosal tumors. Methods A retrospective study was performed on the data of 6 patients with submucosal tumor undergoing ESSD in Nanjing Drum Tower Hospital from October 2016 to February 2017. The surgery time, surgical success rate, postoperative pathology and complications were analyzed. Results All patients were successfully completed surgery. One patient had serosal perforation. The mean diameter of tumor was 27.5±10.0 mm. The mean surgery time was 49±18 min. The postoperative pathology of lesions was very low risk stromal tumor. No serious complications occurred. Conclusion ESSD is safe and reliable for patients with tumor originated from muscularis propria.
