title: Posterior duodenal ulcer: acute free perforation into the lesser sac.
abstract: Perforation of a peptic ulcer located on the posterior wall of the duodenum is very rare. We present here three cases with acute and free perforation of a posterior duodenal ulcer with a fatal outcome. To the best of our knowledge such an acute free perforation has not been previously published.
