Abstract

Purpose:

The aim of this study was to compare the oncologic results of endoscopic submucosal dissection (ESD) for early gastric cancers (EGC) in remnant stomachs (RS) with results of ESD for EGC in normal stomachs (NS).

Methods:

From 2002 to 2013, ESD was performed for 583 EGC lesions. ESD of the RS was performed for 34 lesions.

Results:

Two patients with EGC in the NS and 1 patient with EGC in the RS died from these gastric cancers. In all patients, the ESD treatments were considered outside of indications according to the pathologic results. The 5-year cause-specific survival rate was 99.5% for EGC patients with NS and 96.2% for EGC patients with RS. The 5-year overall survival rates were 88.4% for patients with NS and 58.4% for patients with RS.

Conclusions:

On the basis of the favorable long-term oncologic outcomes, ESD for EGC in the RS can be considered feasible in clinical practice.
