Laparoscopic hernia repair has become popular due to its rapid recovery time, fewer postoperative complications, and less chronic pain compared with conventional approaches. Currently, laparoscopic hernia repair is also used for more complex pathogenesis, including extra-anatomic bypass surgery for femoral artery. To the best of our knowledge, cases of inguinal hernia after femoral arterial bypass are extremely rare. We report the case of a 77-year-old Japanese man who was diagnosed with inguinal hernia after a previous left external iliac artery-right common femoral artery bypass. We used a hybrid laparoscopic and anterior approach, and the procedure was completed successfully without perioperative complications. A laparoscopic approach is useful for the diagnosis and treatment of inguinal hernia after extra-anatomic bypass surgery for femoral artery. While complicated, the addition of anterior reinforcement should be considered in cases of insufficient preperitoneal repair using transabdominal preperitoneal patch plasty.
