Core Tip

Core tip: Sleep deprivation affects brain activation, and therefore disturbs cognitive ability and reduces work efficiency. In the clinical field, night duty (ND) might affect surgical outcomes and the number of medical errors. In this study, we examined the influence of ND on endoscopic therapy for biliary duct stones. The procedure was significantly longer when performed by endoscopists after they had been on ND. The time required for endoscopic therapy for bile duct stones might be influenced by ND.
