| Other Abstract | [Objective] (1) To investigate the general characteristics of the upper gastrointestinal submucosal tumor; (2) To explore the diagnostic and therapeutic value of the endoscopy and endoscopic ultrasound (EUS), the efficacy and safety of endoscopic resection ways of upper gastrointestinal submucosal tumor.
[Method]SMT was diagnosis by ordinary endoscopy, endoscopic ultrasound (EUS), with the consent of the patients and their families, there were 65 cases of patients who willing to treat the tumor with endoscopic, respectively patient with needle-knife resection, direct snare resection, endoscopic mucosal resection ( EMR), endoscopic submucosal dissection (ESD), After that， routine pathological examination of the resected specimens and regular endoscopic follow-up was taken，venous aneurysm were not within endoscopic treatment.
[Results] (1) 75 patients, male 39, female 36 cases; located in the esophagus 41 cases, 30 cases of stomach, duodenum 4 cases; maximum diameter was about 4.8cm and minimum diameter was 0.5cm,the diameter of tumor 2cm were so common, leiomyoma account for 52% proportion, stromal tumors accounted for 24%. (2) EUS and pathologic examination confirmed 75 cases , 68 cases had the pathological results, six cases of cysts and one cases of venous aneurysm did not taken pathological examination; 6 cases of lesions were misdiagnosed: two cases of leiomyoma, one case of leiomyosarcoma, one gastrointestinal stromal tumor(GIST), of 75 patients, 9 cases were taken surgery, 65 patients were taken endoscopic treatment ,6 cases of cysts line and create a drainage, 52cases of endoscopic treatment were completely resected for once. 5 cases which did not treat the lesions complete one-time after EMR, 1 case did not resect the lesions completely one-time after ESD. 8 cases had mild retrosternal pain, 4 cases had elevated body temperature, 5 cases had postoperative nausea. All of the cases did not had perforation occurred. all cases had been taken follow-up ranging from 6 to 24 months, and there was no long-term complications or recurrence.
[Conclusion](1) Gastrointestinal submucosal tumor is most common in esophageal,
Male patients and female incidence is no significant difference; the tumor’s clinical symptom is not obvious. Have difficulty swallowing, esophageal tuberculosis should be considered.(2) Endoscopic ultrasonography for upper gastrointestinal submucosal tumor has high diagnostic value.（3）Endoscopic treatment of SMT is safe and effect... |
