Handlebar Trauma Causing Small Bowel Hernia with Jejunal Perforation

An 11-year-old boy was admitted to emergency department with abdominal pain, bilious vomiting and rectal bleeding one day after falling from bicycle. He stated that he landed directly onto the handlebar through his left lower quadrant of the abdomen. Physical examination revealed a soft tissue bulge, tenderness and defense in the left lower quadrant without any head or skeletal injury. His abdomen was soft with no evidence of peritoneal irritation. The patient’s vital signs, radiographs and blood tests (hemoglobin, 14.4 g/dl; hematocrit, 43.0%; wight blood cell count, 6x103/mm3; C-reactive protein, 10 mg/ dl; Sodium (Na), 130 mmol/L) were within normal limits. Ultrasound demonstrated intra-abdominal fluid and herniation of a small bowel loop through the abdominal wall at left lower quadrant. Computed tomography (CT) of the abdomen revealed the herniation of jejunal loop through a defect in the left lower abdominal wall just lateral to the rectus muscle, segmental ileus due to the herniated bowel segment, intraperitoneal fluid and pneumoperitoneum (Figure).
