[Anastomotic leakage in hepato-pancreato-biliary surgery]

Severe complications following hepato-pancreato-biliary surgery are frequently due to leakage of anastomoses. Local intraoperative and systematic measures can reduce the incidence of leaks and leak-related sequelae. The early identification of leak-related sequelae, such as hemorrhage is pivotal to reduce the mortality risk. Therefore, perioperative risk stratification incorporating surgical and patient risk factors is crucial. The management of anastomotic leaks is complex and an interdisciplinary treatment is therefore recommended. The treatment depends on the institutional expertise, localization, characteristic features of the anastomosis and the onset of insufficiency. This article describes the different concepts of the diagnostics, prevention, consequences and management of anastomotic leakage in hepato-pancreato-biliary surgery in more detail.
