A Case of Inguinal Interparietal Hernia Preoperatively Diagnosed and Laparoscopically Repaired

Abstract

An 86-year-old man presented with a fist-sized bulge in the right inguinal region that had appeared in a standing position for 10 years. A right inguinal hernia was noted during follow-up at the urology department of our hospital for urinary retention, and the patient was referred to our department for examination and treatment. The results of abdominal computed tomography revealed a hernia orifice in the right groin. The hernia sac containing the cecum and terminal ileum progressed to the inguinal canal and cephalad on the ventral side of the external abdominal oblique muscle. Thus, the patient was diagnosed with interparietal hernia, and laparoscopic inguinal hernia repair was performed. The surgical findings included a 3 cm hernia orifice in the right groin, with the cecum aberrantly inserted into the hernia sac. The hernia sac progressed from the internal inguinal ring toward the inguinal canal and cephalad, and the patient was diagnosed with right groin interparietal hernia. The postoperative course was uneventful, and the patient was discharged the day after the surgery. We report a case of inguinal interparietal hernia that was preoperatively diagnosed and laparoscopically repaired.
