RESUMO
INTRODUCTION AND IMPORTANCE: Traumatic abdominal wall hernia (TAWH) is an injury that occurs after an abdominal wall blunt trauma consisting of fasciomuscular rupture and does not present skin penetration. Documenting unique and rare clinical cases, such as traumatic hernia without skin penetration, enriches the medical literature and provides valuable information to identify innovative and optimised approaches for the treatment of similar cases in the future. CASE PRESENTATION: 48-year-old female with no significant medical history presented to the emergency room after being directly hit by a 1200 kg vehicle while standing in the street. Clinical examination revealed a TAWH with total elevation and total loss of insertion of all abdominal wall muscles on the right side, and no involvement of the overlying skin secondary to the mechanism of trauma. The patient agreed to surgical management after being thoroughly informed about the procedure. Surgical exploration was performed with the patient in a lateral position, and the incision was made over the hernia sac. A monopolar electrocautery was used to expose the iliac crest and fully visualize the defect before drilling through the iliac crest. Soft macroporous polypropylene mesh repair was guided through the iliac crest and abdominal wall using a suture and secured with knots. The patient showed a satisfactory and favorable progress. DISCUSSION AND CONCLUSIONS: The present surgical technique is recommended for atypical cases of high-strength TAWH.
