TL;DR: Although EGC lesions had poorer features in the surgery group than in the ESD group, ESD was comparable to surgery for EGCs that fulfilled the expanded indication of ESD, with lower rates of acute complication and comparable overall survival.

Incidence and impact of scheduled endoscopic surveillance on recurrence after curative endoscopic resection for early gastric cancer
Kyu Yeon Hahn,Jun Chul Park,Eun Hye Kim,Suji Shin,Chan Hyuk Park,Hyunsoo Chung,Sung Kwan Shin,Sang Kil Lee,Yong Chan Lee +8 more
TL;DR: Scheduled endoscopy surveillance is necessary for detecting recurrent lesions after endoscopic submucosal dissection and might help to detect recurrent lesions at a stage early enough for a curative resection.

Prediction model for non-curative resection of endoscopic submucosal dissection in patients with early gastric cancer
Eun Hye Kim,Jun Chul Park,In Ji Song,Yeong Jin Kim,Dong Hoo Joh,Kyu Yeon Hahn,Yong Kang Lee,Ha Yan Kim,Hyunsoo Chung,Sung Kwan Shin,Sang Kil Lee,Yong Chan Lee +11 more
TL;DR: A validated prediction model can be used to identify patients who will undergo non-curative resection of ESD and can provide useful information for making decisions about the treatment of EGC before performing ESD.

Long-term outcomes after noncurative endoscopic resection of early gastric cancer: the optimal time for additional endoscopic treatment.
TL;DR: In patients with noncurative ESD, additional surgery showed a better long-term outcome; moreover, when a positive lateral resection margin was the only nonCurative factor, additional endoscopic treatment within 3 months could be considered to improve disease-free survival.
