BACKGROUND: Although extragastric recurrence after endoscopic resection of early @entity356 is rare, it is important because of its potentially fatal outcomes. We investigated the patterns of extragastric recurrence after endoscopic resection and evaluated the role of abdominal computed tomography in surveillance. METHODS: Between July 1994 and June 2014, 4915 @entity1 underwent endoscopic resection of early @entity356 . Because of follow-up periods of less than 6  months and consecutive surgery within 1  year, 810 @entity1 were excluded. Thus, 4105 @entity1 were retrospectively reviewed. RESULTS: The median follow-up period was 37  months  (interquartile range 20-59.6  months). The overall incidence of extragastric recurrence was 0.37% (n  =  15). In @entity1 who underwent curative resection, the incidence was 0.14% (n  =  5). There were three recurrences in the absolute indication group, six in the expanded indication group, and six in the beyond expanded indication group. The median time to extragastric recurrence was 17  months  (interquartile range 16.5-43.2  months). Of the 15 extragastric recurrences, 11 were in the regional lymph nodes and 4 were in the liver, adrenal gland, and peritoneum. Sixty percent (9/15) of the extragastric recurrences occurred without @entity75 . Eleven recurrences were detected by abdominal computed tomography, and eight @entity1 underwent curative surgery. CONCLUSIONS: After endoscopic resection of early @entity356 , regional lymph node recurrence is the predominant extragastric recurrence pattern, which can be detected via abdominal computed tomography and cured by rescue surgery. Abdominal computed tomography should be considered as a surveillance method, especially in @entity1 with an expanded indication.
