 The patient was a 64-year-old woman with a history of appendectomy by laparotomy. She presented to our hospital with upper abdominal pain and vomiting. She was diagnosed as having an internal hernia from transverse mesocolon hernia on contrast-enhanced abdominal computed tomography (CT) ; emergency surgery was performed on the same day. On laparoscopic observation, the hernia orifice was seen in the transverse mesocolon to the left of ligament of Treitz. The jejunum was invaginated and it was pulled out of the hernia sac. The hernia orifice was cut open and the transverse mesocolon forming the hernia sac became flat. Since we considered that the intestinal invagination will no longer occur, suture closure was not performed. The patient's course was uneventful, and she was discharged from the hospital on postoperative day 7. We report a relatively rare case of transverse mesocolon hernia which was diagnosed preoperatively and was treated by laparoscopic surgery.
