Obstructive ileus caused by a swallowed foreign body (a "press-through" package) and preexisting adhesions.

A "press-through" package (PTP), because it is large and square-shaped, tends to be caught in the esophagus when swallowed. A rare case of obstructive ileus induced by a PTP that was swallowed by 54-year-old man with a history of diabetes mellitus and acute appendectomy is reported. The PTP was 19 mm x 18 mm and was lodged in the cecum, which was stenosed because of preexisting intestinal adhesions; consequently, the PTP obstructed the ileus. The PTP was surgically removed.
