外傷性腹壁ヘルニアに対し腹腔鏡補助下ヘルニア修復術を施行した１例

Abstract

A 44-year-old man with no significant past medical history presented to the emergency department with a left-sided abdominal bulge that developed after he hit his abdomen against the blunt end of a bicycle motocross handlebar. Abdominal computed tomography showed a left abdominal wall hernia containing a loop of small intestine. The herniated intestine was easily reducible. We made the diagnosis of traumatic abdominal wall hernia ("handlebar" hernia) caused by direct blunt trauma, and performed laparoscopic-assisted herniorrhaphy. Laparoscopy revealed tears in the abdominal wall muscles (transverse abdominal, and internal and external oblique muscles) and bowel injury (Type Ⅰ a). The hernia defect was closed in 2 layers of muscle, along with mesh repair. The patient was discharged on postoperative day 5.Traumatic abdominal wall hernia (TAWH) caused by a handlebar is very rare, and we report our case herein, along with a review of the literature.
