    Background/PurposeThe choice of endoscopic submucosal dissection (ESD) as first line treatment for selected early gastric cancer (EGC) patients was proved as effective as surgical treatment in studies over many countries. Yet there is no such cohort comparison in Taiwan. This study is aimed to describe our experience in ESD treated EGC and to compare the outcomes with those underwent surgical treatment.MethodsThis was a retrospective cohort study reviewing the patients with EGC underwent ESD and surgical treatments in a single tertiary referral center in Taiwan. The primary endpoint was disease specific survival. Recurrence free survival and length of hospital stay were also compared.ResultsThe disease specific survival between indicated ESD and surgery showed no significant difference (cumulative survival 100% vs. 97.03%, p = 0.39), so as the recurrence free survival (cumulative survival 92.31% vs. 94.06%, p = 0.60). In subgroup analyses of ESD treated patients, a non-significant recurrence rate difference between indicated and non-indicated ESD was found (cumulative recurrence 7.69% vs. 20%, p = 0.39) and a higher recurrence rate in patients with non-R0 resection compared with R0 resection (cumulative recurrence 0% vs. 40%, p < 0.01). However, the shorter duration of hospital stay in ESD group was noted in comparison to surgery (mean 5.67 days vs. 15.75 days, p < 0.01). The ESD patients have minor complications including bleeding, perforation and fever than surgery.ConclusionESD is a reasonable first line treatment in selected early gastric cancer in additional to surgery. Pre-treatment evaluation and post-ESD review of curability is crucial to further surveillance program or definite therapy including surgery.Copyright © 2020 Formosan Medical Association.
