Petersen’s hernia often develops early after Roux-en-Y (RY) reconstruction. We experienced Petersen’s herniathat developed 7 years and 6 months after laparotomic gastrectomy. A 77-year-old man was transferred to ourhospital presenting with abdominal pain. He had a history of gastric cancer at 7 years and 6 months previouslyand underwent distal gastrectomy with RY reconstruction. He was diagnosed with internal hernia and underwentemergency surgery. The operative findings revealed an internal jejunal hernia through the space between the mesentery of the Roux limb and the transverse mesocolon (Petersen’s defect). We repaired the incarcerated intestinaltract and closed Petersen’s defect. Petersen’s hernia often occurs in the first or second year due to weight loss aftergastrectomy. However, it can occur even after 5 years postoperatively, when gastric cancer surveillance has beencompleted. Thus, Petersen’s defect should be properly closed at the initial surgery.
