[Routine second look endoscopy after bleeding ulcers].

Treatment of peptic duodenal and gastric ulcers has improved in efficiency and become less invasive. There is still a considerable risk of re-bleeding (15-20%) and the mortality remains high (5-14%). A Danish study from 2000 showed that scheduled second look endoscopy (SLE) the day after the primary intervention decreased the re-bleeding rate. Studies have questioned this and suggest that SLE decreases the risk of re-bleeding, but do not reduce mortality. Since SLE is debated and a recent national survey found a variable practice, the evidence has been reviewed critically.
