黏膜下隧道法内镜切除术治疗上消化道黏膜下肿瘤的临床疗效分析

Cfinical efficacy analysis of submucosal tunneling endoscopic resection for upper gastrointestinal submucosal tumors

目的探讨黏膜下隧道法内镜切除术（STER）治疗上消化道黏膜下肿瘤（SMTs）的疗效及临床应用价值。方法回顾性分析2015年1月至2016年6月在解放军总医院经STER治疗的44例上消化道SMTs患者的内镜及临床资料。结果肿瘤完整切除率为88．6％（39／44），手术时间为（60．1±30．6）min，平均住院时间为（10．1±3．3）d，并发症发生率为6．8％（3／44）。内镜超声检查（EUS）与病理诊断、EUS测量病灶大小与实际标本大小及EUS与CT判断SMT生长方向均具有一致性。结论STER治疗SMTs具有完整切除率高、手术及住院时间短及并发症少等特点，且EUS联合CT可作为术前评估手段。

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 rain. 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.
