Clinical Research On Endoscopic Diagnosis And Treatment Value In Submucosal Tumors Of Upper Gastrointestinal Tract

[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 were65cases 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)75patients, male39, female36cases; located in the esophagus41cases,30cases of stomach, duodenum4cases; maximum diameter was about4.8cm and minimum diameter was0.5cm,the diameter of tumor2cm were so common, leiomyoma account for52%proportion, stromal tumors accounted for24%.(2) EUS and pathologic examination confirmed75cases,68cases had the pathological results, six cases of cysts and one cases of venous aneurysm did not taken pathological examination;6cases of lesions were misdiagnosed:two cases of leiomyoma, one case of leiomyosarcoma, one gastrointestinal stromal tumor(GIST). of75patients,9cases were taken surgery,65patients were taken endoscopic treatment,6cases of cysts line and create a drainage,52cases of endoscopic treatment were completely resected for once.5cases which did not treat the lesions complete one-time after EMR,1case did not resect the lesions completely one-time after ESD.8cases had mild retrosternal pain.4cases had elevated body temperature,5cases had postoperative nausea. All of the cases did not had perforation occurred, all cases had been taken follow-up ranging from6to24months, 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 effective.
