The overview of the bile system NENs from 1986 to 2016. A From 1986 to 2016, the incidence of bile system NEN is rising. B From 1986 to 2016, a total of 233 NEN patients received surgery. Among them, 119 patients (51.07%) patients were gallbladder NENs, 82 patients were AOV NENs, and 32 patients were EBD NENs. C The postoperative overall survival of biliary tract neuroendocrine neoplasm has better overall survival than that of the gallbladder neuroendocrine neoplasm (Log-rank test, P < 0.0001), while no significant differences were observed between the AOV NENs and EBD NENs in overall survival
