Reduction en masse of inguinal hernia after self-reduction: a case report.

BACKGROUND

Reduction en mass (REM) is one of the rare complications of inguinal hernia reduction. Although REM can be detected on the basis of specific computed tomography (CT) scan findings, many radiologists are not familiar with its radiological appearance because of the scarcity of this complication, which may cause a delay in diagnosis.

CASE PRESENTATION: The patient reported in this article was a 50-year-old Persian man with a history of inguinal hernia, who had been referred with the periumbilical pain that radiated to the right lower quadrant and developed following hernia replacement by the patient himself. REM diagnosis was based on clinical examination and CT scan findings, and surgical treatment was performed by the Lichtenstein repair and mesh implantation.

CONCLUSIONS

Although REM usually occurs after reduction with compression in the inguinal hernia, this unique case report highlighted the possibility of REM after self-reduction. Surgeons and radiologists should consider REM in patients with a history of inguinal hernia presenting with intestinal obstruction symptoms, even without any apparent signs of hernia in the physical examination.
