Endoscopic submucosal dissection for gastric tumors in various types of remnant stomach.
OBJECTIVE
The aim of this study was to examine the clinical outcomes of endoscopic submucosal dissection (ESD) for gastric tumors in various types of remnant stomach.


METHODS
Between January 2002 and March 2013, ESD was performed for 750 gastric tumors. Of these lesions, 49 were in a remnant stomach, and were included in the study.


RESULTS
The en bloc resection rate was 100 %. The curative resection rate was 82 %. The rate of perforation was high in patients with gastric conduits (28.6 %). Perforation was significantly more common in patients with lesions located on the suture line (4.9 % vs. 50.0 %; P = 0.0043).


CONCLUSIONS
ESD for gastric tumors in the remnant stomach can be considered feasible and safe in clinical practice. However, the procedure is technically more difficult in patients with a gastric conduit, due to the increased risk of perforation at the suture line.
