Plain radiographs of an 88-year-old woman who had experienced vomiting and abdominal distention for 3 days revealed a severely obstructed ileus, and abdominopelvic computed tomography revealed an incarcerated Morgagni hernia. The endoscope was passed through the constrictions from the diaphragmatic indentations and a thin catheter was placed for decompression. The obstructive ileus regressed markedly after the procedure; the patient underwent elective laparoscopic repair of the hernia 1 week later. This is believed to be the first case of endoscopic preoperative decompression for an incarcerated Morgagni hernia.
