We report a case of a paraesophageal hernia, which was successfully treated with laparoscopic surgery after a natural history of eight years. Eight years before surgery only the fundus of the stomach was included in the hernia sac. At surgery, although the gastroesophageal junction and fundus were found in their normal positions, the distal half of the stomach and the omentum were pulled into the thorax, which demonstrated an organoaxial gastric volvulus. As the omentum tightly adhered to the top of the hernia sac and there was no tight adhesion between the stomach and hernia sac, the omentum could serve as the lead point for the gastric volvulus. This patient was successfully treated with laparoscopic surgery and is presently in good condition without any recurrence of the hernia.
