Background And Study Aims:
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.
Patients And 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).
Conclusion:
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.
