Acute gastroesophageal intussusception in a patient with pneumomediastinum, pneumoperitoneum, and extensive subcutaneous emphysema resulting from iatrogenic colonic perforation.

Acute gastroesophageal intussusception is a rare condition in which the stomach invaginates into the adjacent esophagus. We report a case of acute gastroesophageal intussusception with massive pneumomediastinum, pneumoperitoneum, and subcutaneous emphysema, effectively treated with conservative management.
