[Endoscopic complication: unsuspected impact of gastroscope into the oesophagus in a patient with a large hiatal hernia].

Gastroscopy is used world-wide and it is considered as a safe procedure. In a case study we describe an impaction of a gastroscope into the oesophagus. A gastroscopy in full narcosis was performed on a patient with a large size hiatal hernia. During the procedure the gastroscope recurved into the oesophagus. With the assistance of another gastroscope and fluoroscopic guidance the gastroscope was removed successfully. This complication may occur more often than described in literature.
