Abstract

BACKGROUND:

Although recent guidelines for endoscopic submucosal dissection (ESD) as treatment for early gastric cancer (EGC) recommend noninterruption of low-dose aspirin (LDA) perioperatively, this strategy is controversial. It was our practice to interrupt LDA therapy 5-7 days before to ESD until December 2010, when we instituted the new guidelines and performed ESD without interrupting LDA therapy. Our purpose in this study was to confirm the validity of noninterrupted use of LDA in patients undergoing ESD for EGC.

METHODS:

We studied 78 consecutive patients with 94 EGCs who were routinely taking LDA and were treated by ESD at Hiroshima University Hospital between April 2005 and June 2012. The patients were of two groups: those in whom LDA was interrupted perioperatively (53 patients with 66 EGCs) and those in whom LDA was continued perioperatively (25 patients with 28 EGCs).

RESULTS:

The complete resection rate was 92.4 % (61/66) in the LDA-interrupted group and 100 % (28/28) in the LDA-continued group. Incidences of poor bleeding control during the procedure and bleeding after procedure were 10.6 % (7/66) and 4.8 % (3/66), respectively, in the LDA-interrupted group and 7.1 % (2/28) and 3.6 % (1/28) in the LDA-continued group. Two patients in the interrupted-LDA group suffered cerebrovascular infarction before ESD, and 2 patients in this group suffered acute myocardial infarction after ESD.

CONCLUSIONS:

Our data suggest that continued use of LDA does not increase the risk of bleeding during or after ESD for EGC and does decrease the risk of ischemic events.
