Abstract

Aim: To compare the efficacy and safety of endoscopic resection (ER) and surgery for the treatment of early gastric cancer and precancerous lesions. Methods: Databases, such as PubMed, EMBASE, Cochrane Library, and Science Citation Index, from 2000 to 2016, were searched for eligible articles. In this meta-analysis, the main outcome measurements were local recurrence, complications, metachronous lesions, hospital stay, and 5-year overall survival. Results: Nine trials were identified and a total of 2748 patients were included. The rate of complication was higher in the surgery group compared with the ER group (OR 0.41; 95 % CI 0.30–0.55). The rates of local recurrence and metachronous lesions were lower in the surgery group (OR 0.03; 95 % CI 0.00–0.06; OR 8.76; 95 % CI 4.17–18.41). The hospital stay was shorter in the ER group (mean difference −6.96; 95 % CI −7.94 to −5.99). The 5-year overall survival rate did not significantly differ between the two groups (OR 1.23; 95 % CI 1.03–1.47). Conclusions: We provided evidence that, ER was comparable to surgery in terms of the 5-year overall survival. In addition, ER had a lower rate of complications and shorter hospital stay, but a higher rate of local recurrence and metachronous lesions for the treatment of early gastric cancer and precancerous lesions.
