Abstract
A 20-year-old man, who had been involved in a traffic accident while driving a scooter, was transferred to our facility. A computed tomography examination showed a 4 cm × 6 cm defect in the aponeurosis adjacent to the left rectus abdominis and a herniation of the small intestine below the subcutaneous tissue. We suspected a traumatic Spigelian herniation and operated immediately. There was a defect of approximately 7 cm in the aponeurosis of the external abdominal oblique muscle and transversus abdominis, along the rectus sheath. The final diagnosis was a traumatic Spigelian herniation. There was no other damage to the abdomen, and we performed a simple closure of the fascia. The patient was uneventfully discharged on postoperative day 7 and remained well, with no recurrence of herniation at the 21-month follow-up examination. Given that traumatic Spigelian herniation is rarely reported in our country, we have reported this case, along with a review of the literature.
