Endoscopic resection for XXXX with long-term outcomes.

@entity1 @entity808 @entity5 @entity3 @entity356
BACKGROUND: @entity356 is not so recognized by clinicians as its counterparts. The efficacy of endoscopic resection has not been described yet. Our aim was to assess the efficacy and safety of endoscopic resection in the management of @entity356 . METHODS: Retrospective data were reviewed from January 2008 to December 2013 in our center. Fourteen @entity1 who had endoscopic resection with the final pathology result of @entity356 were included in the study. RESULTS: Of the 14 @entity1 , there were 12 females and two males. The median age was 59  years (range 32-83). Thirteen @entity5 (92.9  %) were from the muscularis propria and one located in the submucosa. Endoscopic en bloc resection was achieved in 12 @entity1 (12/14, 85.7  %), including seven cases of endoscopic full-thickness resection (EFTR). The mean resected @entity5 size was 1.73      1.10  cm (range 0.3-4.0  cm). In one case, endoscopic resection was suspended due to the limited experience of EFTR during the early period of the study. In another case, due to the difficult @entity5 location (gastric angle) and extraluminal growth pattern, the @entity1 was referred to laparoscopic surgery. In the 12 successful endoscopic resection cases, during the median follow-up time of 4  years (range 17-77  months, one @entity1 lost), no @entity5 residue, recurrence or @entity3 was found. CONCLUSIONS: Endoscopic resection is safe and effective in treating @entity356 with excellent long-term outcomes. However, it should be performed with caution because @entity808 is mainly located in the deep muscular layer, which leads to the full-thickness resection of gastric wall.
