抄録 Introduction: The aim of this study was to evaluate the outcomes of combined endoscopic submucosal dissection (ESD) with sentinel node navigation surgery (ESN) or laparoscopic lymph node dissection (LLND) and endoscopic full-thickness resection (EFTGR) with laparoscopic regional lymph node dissection (hybrid natural orifice transluminal endoscopic surgery, hybrid NOTES) for early gastric cancer (EGC). Methods: This is a retrospective analysis using prospectively collected data at a single tertiary referral center. A total of 80 patients with EGC underwent combined ESD with ESN or LLND and hybrid NOTES between February 2007 and January 2013. Results: The curative resection rate was 86.3% (ESN 73.9% vs. ESD with LLND 100% vs. hybrid NOTES 79.2 %, respectively). Histologically, 33 were mucosal cancers, and 45 were submucosal cancers. There were 50 undifferentiated cancers. The median tumor size was 2.3 cm (range, 0.6-7 cm). Lymphovascular invasion was found in 27 with 3 lymph node metastasis. Incomplete resection was shown in 11 (8 lateral and 3 vertical tumor-positive margins). Eight patients underwent additional gastrectomy. During the median follow-up of 23 months (range, 3-73 months), none showed local recurrence or lymph node metastasis. Conclusion: ESN, combined ESD with LLND and hybrid NOTES showed favorable pathologic and clinical outcomes.
