Background/Aims: Evidence that general anesthesia (GA) reduces the operative time of esophageal endoscopic submucosal dissection(ESD) is currently insuffcient. This study aims to evaluate the effcacy and safety of esophageal ESD under GA. Methods: A total of 227 lesions from 198 consecutive patients with superficial esophageal neoplasms treated by ESD at 3 Japaneseinstitutions between April 2011 and September 2017 were included in this retrospective study. For ESD, GA and deep sedation (DS)were used in 102 (51.5%, GA group) and 96 patients (48.5%, DS group), respectively. Results: There were no statistically significant differences in age, sex, or comorbidities between the groups. In the GA group, the tumorsize was larger (21 [3–77] mm vs. 14 [3–63] mm, p<0.001), luminal circumference was larger (≥2/3; 13.9% vs. 5.4%, p=0.042), proceduretime was shorter (28 [5–202] min vs. 40 [8–249] min, p<0.001), and submucosal dissection speed was faster (25.2 [7.8–157.2] mm2 /minvs. 16.2 [2.4–41.3] mm2 /min, p<0.001). The rates of intraoperative perforation and aspiration pneumonia were lower in the GA group,but the difference did not achieve statistical significance (p=0.242 and p=0.242). Conclusions: GA shortens the procedure time of esophageal ESD.

There are many problems that used fishing lights in Japanese fisheries industry. It’s a particularly serious problem that is prolongation of new fisherman nature. Fishery skill acquirement that using fishing lights needs to get the feeling and experience of many time. This problem is cause of this thing. To solve this problem, we consider a LED underwater fishing lights automatic control system and development of underwater illuminance distribution simulator. This paper introduces about underwater illuminance distribution simulator of interface with the automatic brightness controllable LED underwater fishing lights in great detail. Interface of the automatic brightness controllable LED underwater fishing lights have to lead to dissipative modulus. We needed turbidity measurement. We measure coastal areas and, lend to dissipative modulus. From these results, we became possible to interface of turbidity information with automatic brightness controllable LED underwater fishing lights.
