源于固有肌层的胃间质瘤行内镜下切除闭合术的可行性研究

目的 评价对来源于固有肌层的非腔内生长型胃间质瘤施行内镜下切除闭合术治疗的可行性.方法 46例患者经胃镜和超声内镜检查诊断为起源于固有肌层的非腔内生长型胃黏膜下肿瘤,采用内镜下切除闭合术切除肿瘤,行常规病理及免疫组化检查后证实为间质瘤.术后内镜随访,观察治疗效果及有无并发症.结果 46例非腔内生长型胃间质瘤经内镜下切除闭合术治疗后均完全切除,切除后2例保留完整的浆膜层,44例术中遗留切口,切口最大径1.5 cm,行钛夹夹闭切口,予抑酸、胃肠减压、静脉应用抗生素等辅助治疗.病理报告全层切除46例,肿瘤直径为0.5～3.7 cm.44例患者术后48～72 h后进食,未见明显不适;2例术后出现气腹、局限性腹膜炎,其中1例切口1.5 cm患者术后第2天切口裂开,再次钛夹夹闭裂开切口,辅助治疗10～12 d,该2例患者痊愈出院.术后6个月随访,所有患者切口均形成白色溃疡瘢痕.结论 对于非腔内生长型胃间质瘤,内镜下切除闭合术是一种安全、经济、创伤小的治疗方式,值得临床推广.

Feasibility of endoscopic resection-closure for non-intraluminal gastric stromal tumors originating from the muscularis propria layer

Objective To evaluate the feasibility of endoscopic resection and closure for non-intraluminal gastric stromal tumors originating from the muscularis propria layer.Methods Included in the study were 46 patients with gastric submucosal lesions originating from the muscularis propria layer, detected by gastroscopy and endoscopic ultrasonography.The lesions were removed by endoscopic resection and closure, which were further diagnosed as stromal tumor by means of pathologic and immunohistochemical examinations.The patients were followed up with endoscopy for evaluation of therapeutic effect and complications.Results All lesions were successfully removed, with serosa layer remained in 2 cases and full layer resection in other 44, which were all closed by endoscopic clips.Combination managements of acid suppression,gastrointestinal decompression and intravenous antibiotics were applied in all patients.Pathology reports confirmed complete resection of all lesions, with 0.5 to 3.7 cm in diameter.Normal diet was restored in 44 patients 48 ～ 72 h after the procedure.Pneumoperitoneum and focal peritonitis occurred in 2 cases, one of which underwent rupture and was clamped again.The 2 patients recovered after 10-12 days of conservative treatments.Follow-up endoscopy revealed white ulcerous scar in all cases.Conclusion Endoscopic resection and closure therapy is a safe, economic and less invasive treatment for non-intraluminal gastric stromal tumors originating from the muscularis propria layer.
