Factors Associated With Outcomes in Endoscopic Submucosal Dissection of Gastric Cardia Tumors

Tumors of the gastric cardia are among the most technically difficult lesions to remove by endoscopic submucosal dissection (ESD). This study aimed to evaluate the therapeutic outcomes of ESD in gastric cardia tumors according to clinicopathologic characteristics, and to assess the predictive factors for incomplete resection. We conducted a retrospective observational study of 82 patients with adenomas and early cancers of the gastric cardia who...
