Although the advantages of endoscopic submucosal dissection (ESD) are well established, there are important limitations that relate to its higher cost and higher rate of complications compared with endoscopic mucosal resection. This study assessed the therapeutic safety and efficacy of ESD in the treatment of small gastric dysplasia and early gastric cancer (EGC) located within the antrum in an outpatient setting, and it compared the results with those from patients admitted to hospital for ESD treatment.
This study was a retrospective analysis of a prospectively maintained database. We reviewed consecutive patients with EGC or gastric dysplasia who underwent ESD between October 2007 and May 2008. The lesions were smaller than 2 cm and were located in the antrum. We analyzed 105 lesions in 105 patients. The patients were assigned to two groups according to each patient's preference.
The overall rates of complete resection were 98.1% in the inpatients group and 94.3% in the outpatients group. Immediate bleeding occurred in four inpatients, which included one patient in the outpatient group. Delayed bleeding occurred in one inpatient within 24 hours of the procedure. Macroperforations did not occur in either group. A microperforation was found in one outpatient.
The safety and efficacy of ESD used to treat small gastric tumors in the antrum in an outpatient setting appeared to be similar to the safety and efficacy of ESD used to treat patients who were admitted to the hospital.
