Endoscopic esophageal submucosal tunnel resection of gastric fundus-cardiac tumors originating from muscularis propria

Objective To investigate the clinical value of endoscopic esophageal submucosal tunnel resection of gastric fundus-cardiac tumors originating from muscularis propria. Methods Clinical date of 18 patients with gastric fundus-cardiac submucosal tumors originating from muscularis propria who underwent endoscopic esophageal submucosal tunnel resection from January 2011 to December 2011 were retrospectively collected and analyzed. Results All lesions were successfully and completely resected in 18 patients, with sizes ranging from 0. 7 cm to 7. 2 cm, mean （2. 43 ± 1.91 ） em. Pneumoretroperitoneum, pneumomediastinum and pneumohypoderma occured during the procedure in 2 cases, but spontaneously resolved in 3 days. Fever with increased WBC within 24 h after the procedure occurred in one patient, and was cured in two days with antibiotics. There were no severe complications including bleeding, perforation or death. All patients could have liquid diet 3 days later after the operation. Follow-up endoscopy at 1 week after the operation showed a healing of esophageal incision. Conclusion Endoscopic esophageal submucosal tunnel resection is a safe and effective method for gastric fundus-cardiac submucosal tumors originating from the muscularis propria, lessening the difficuhy of traditional endoscopic resection.
