腹腔鏡下胃全摘術後に2度のPetersen’s hernia修復術を要した1例

Petersen’s hernia is a type of internal hernia that may occur after Roux-en-Y reconstruction. Some surgeons suture Petersen’s defect for prevention of Petersen’s hernia. We report a case of recurrent Petersen’s hernia. A fifty-something man underwent laparoscopic-assisted total gastrectomy with antecolic Roux-en-Y reconstruction for gastric cancer. Petersen’s hernia occurred ６ months later. We closed Petersen’s defect by absorbable suture. However, he experienced recurrence２months later. The defect had not been successfully closed and there was no adhesion ; thus, we sutured Petersen’s defect again, more tightly than before. Additionally, we investigated different approaches for closing Petersen’s defect due to our experience of recurrent Petersen’s hernia.
