PURPOSE: A recently developed endoscopic mucosal resection (EMR) procedure, endoscopic submucosal dissection (ESD), makes en bloc resection possible for @entity1697 regardless of lesion size. ESD involves deeper and wider dissection of the gastric wall and may therefore increase the difficulty of subsequent totally laparoscopic gastrectomy (TLG) and the risk of complications. However, the influence of ESD on subsequent TLG has yet to be demonstrated. The purpose of the present study was to clarify the influence of ESD on subsequent TLG. METHODS: Between March 2006 and December 2013, we retrospectively collected data of 38 @entity1 undergoing TLG with ESD (ESD group) and propensity score-matched 38 @entity1 undergone TLG without ESD (non-ESD group) for treatment of @entity356 at Tonan Hospital and Hokkaido University Hospital. The covariates for propensity score matching were as follows: age, sex, American Society of Anesthesiologists score, body mass index, and type of surgery. Clinicopathologic characteristics and surgical outcomes were compared between the two groups. RESULTS: Operative times for TLG in ESD group and non-ESD group were 228.2        53.9 and 228.1        52.7  min (P   =   0.989), and @entity190 was 45.7        83.0 and 71.3        74.5  g, respectively (P   =   0.161). There were no significant differences between the groups of ESD and non-ESD in postoperative recovery and postoperative complications. In totally laparoscopic distal gastrectomy (TLDG), the @entity1 with ESD-resected specimens of more than 50  mm in diameter had significantly longer operative times (P   =   0.009). CONCLUSIONS: In this study, TLG is a feasible procedure treatment of @entity356 regardless of ESD. However, TLDG is more difficult in cases where the ESD-resected specimen is more than 50  mm in diameter.
