RESUMO
Objective To investigate the clinical efficacy and application value of submucosal tunneling endoscopic resection(STER)for upper gastrointestinal submucosal tumors(SMTs). Methods A retrospective analysis was performed on the endoscopic and clinical data of 44 cases with SMTs who received STER from January 2015 to June 2016 in Chinese PLA General Hospital. Results The rate of complete resection was 88.6%(39/44). The operating time was 60.1±30.6 min. The hospitalization time was 10.1± 3.3 days. The rate of complications was 6.8%(3/44). The diagnosis of SMTs by pathology and endoscopic ultrasonography(EUS),the size of SMTs measured by EUS and ruler after STER,and the growing direction judged by EUS and CT were consistent. Conclusion STER for SMTs has a higher complete resection rate, shorter operating time and hospitalization time, and fewer complications. EUS combined with CT is an effective method for preoperative evaluation.
