Abstract: Objective: We present a case of small intestinal perforation within an inguinal hernia following low-energy indirect trauma.Patient: A 55-year-old man with a known right inguinal hernia which had no prior indication for surgery developed acute right groin pain after sudden braking caused his scooter handlebar to strike his right thigh.Results: Physical examination and computed tomography (CT) scan of the abdomen and pelvis revealed multiple pockets of extraluminal air within the hernia sac, as well as gas bubbles in the surrounding intestinal contents. Based on these findings, we made a diagnosis of small intestinal perforation within the inguinal hernia.Conclusion: Small intestinal perforation within an inguinal hernia is an uncommon but potentially life-threatening complication requiring emergent surgical intervention. Delays in diagnosis and management can lead to peritonitis, abscess formation, sepsis, and prolonged hospitalization. Therefore, clinicians should maintain a high index of suspicion for intestinal perforation in patients with inguinal hernias, even in the absence of direct trauma or subsequent low-energy injuries.
