Values are mean ± SD or n (%) of patients. aAntiplatelet agents include aspirin, nonsteroidal anti-inflammatory drugs, and plavix. These medications were discontinued in all patients prior to endoscopic submucosal dissection. SD: standard deviation; M: sedation with midazolam; MP: sedation with midazolam plus intermittent propofol injection; ASA: American Society of Anesthesiologists.
