UNDERWATER ENDOSCOPIC MUCOSAL RESECTION (EMR) FOR TREATING GASTRIC NEOPLASMS

Aims Underwater endoscopic mucosal resection (UEMR) has been developed and widely used in the colon. Its application in the stomach has been reported few. This study aimed to evaluate the efficacy and the safety of UEMR in the stomach (G-UEMR).

Methods From January 2014 to June 2021, 32 consecutive patients who had or had been suspected gastric neoplasms were enrolled in this retrospective uncontrolled study. They were resected using G-UEMR. Short term outcomes were assessed using a database from the medical records.

Results Among 32 lesions, 22 were neoplastic lesions including adenoma and adenocarcinoma, 5 were hyperplastic polyps, 2 were submucosal lesions. 3 were without tumor though the neoplasm was suspected in prior endoscopy. Mean size was 12.7mm, mean procedure time was 5.5min. R0 resections were obtained in all included early gastric cancer (n=15). There were no immediate complications but an aspiration pneumonia occurred in one patient.

Conclusions G-UEMR appears to be a safe, easy, and effective for treating small gastric lesions including neoplasms.
