Abstract
A 62-year-old woman consulted a local hospital after she was informed of an abnormality in the mediastinal shadow on her chest radiograph. Upper gastrointestinal series revealed no apparent abnormalities ; however, lower gastrointestinal series and CT scan revealed that the transverse colon had migrated into the mediastinum through the esophageal hiatus. Therefore, the patient was referred to our department for surgery. Subsequently, we performed laparoscopic surgery. We found that the transverse colon and the omentum did not contain ischemic-necrotic lesions and were incarcerated through the esophageal hiatus and that the gastroesophageal junction and the gastric fundus remained in their normal positions. We sutured the hernial orifice and performed a Toupet fundoplication. Neither complications nor recurrence has been reported during the first postoperative year.
