Background: The patients with early gastric cancer who have undergone incomplete endoscopic resection (ER) generally need additional surgery because of the possibility of lymph node metastasis. The aim of study was to evaluate the optimal time interval from ER to additive surgery by evaluating the effect of time interval on the surgical and oncological outcomes. Methods: We analyzed 154 patients who underwent additive gastrectomy after incomplete ER at Severance and Gangnam Severance Hospitals. The time interval point, at which operative time and estimated intraoperative blood loss (EBL) of the earlier operation group and the later operation group showed the greatest disparities, was evaluated. The patients were divided into 2 groups according to the time interval point, as the earlier operation group (group A) and the later operation group (group B). We retrospectively evaluated the clinicopathological characteristics and surgical and oncological outcomes. Results: The greatest difference between operative time and EBL was in the groups who underwent operation before and after 29 days. Of the 154 patients, 78 were in group A (≤29 days) and 76 in group B (>29 days). There were no differences in the clinicopathological characteristics and oncological outcomes except for tumor size. The operative time and EBL were significantly longer and more in group A compared with group B. Conclusions: The time interval between ER and additive surgery is associated with surgical outcomes. Additive surgery at about 1 month after ER may be optimal for better surgical outcomes without affecting the oncological outcomes.
