Efficacy and safety of endoscopic submucosal dissection for gastric epithelial neoplasia in elderly patients aged 80 years and older

Endoscopic submucosal dissection (ESD) has been widely used in gastric tumor as a minimally invasive treatment. The efficacy and safety of ESD is still unclear in the elderly who have high frequency comorbidities. The aim of this study is to evaluate the efficacy and safety of ESD for gastric epithelial neoplasia in patients aged 80 years and older.
Between March 2013 and July 2017, a total of 438 gastric epithelial neoplasia patients treated with ESD were analyzed. Clinical outcomes including en bloc and complete resection rates, adverse events (AE) related procedure and sedation were compared between the elderly group and the non-elderly group.
Sex, Body Mass Index, medication history and American Society of Anesthesiologists physical status did not differ between the two groups. Tumor characteristics except size of resected specimen (elderly vs. non-elderly; 36.5 ± 10.5 vs. 32.3 ± 8.7 mm, p < 0.011) did not differ. There were no significant differences in AE-related sedation. En bloc resection (elderly vs. non-elderly; 100% vs. 98.3%, p = 0.454), and complete resection rate (elderly vs. non-elderly; 93.8% vs. 96.3%, p = 0.471) did not differ significantly between the two groups. Procedure time, hospital stay, AE-related procedure and delayed bleeding were also similar between the two groups. However, procedure time of preventive hemostasis (elderly vs. non-elderly; 10.4 ± 7.7 vs. 7.4 ± 5.2 min, p = 0.040) was significantly higher in the elderly group.
ESD for gastric epithelial neoplasia is effective and safe in elderly patients ≥ 80 years as in non-elderly patients.
