Gastric schwannoma after Nissen fundoplication. A rare complication?

Surgical repair of an hiatal hernia results in changes in the local anatomy of the cardia and fundus that may be difficult to interpret by radiological examination. Endoscopy can clarify the radiological changes resulting from surgery, such as pseudodiverticula and pseudotumors, and, when conducted as part of the routine follow-up program, may reveal uncommon complications.
