Endoscopic minimally invasive therapy for submucosal tumors of the esophagus: clinical and pathological studies / 医学研究生学报

ABSTRACT

Objective:To evaluate the effectiveness of endoscopic minimally invasive treatment for submucosal tumors of the esophagus.Methods:Included in the study were 33 patients with esophageal submucosal tumors,male 23 and female 10 cases,aged 34-85 years(average 51.2).The lesions were removed by means of endoscopic mucosal resection(EMR),or stripping-resection method,i.e.,first stripped by a needle knife and followed by "injection and cut".Results:All the lesions were resected completely by endoscopic minimally invasive methods.Of 33 lesions,15 cases were undertook EMR,and 18 cases were treated by stripping-resection method.Except 5 cases of treatable bleeding,and 6 cases of post-operative substernal pain,no other complications were found.Pathological exam and immunohistochemical study showed that 25 cases were esophageal leiomyoma,3 cases of stromal tumor,2 cases of lipoma,2 cases of haemangioma and 1 case of submucoal cyst.No recurrence was found during the follow-up of 2-30 months. Conclusion:Endoscopic minimally invasive therapy is effective and safe for the treatment of esophageal submucosal tumors.
