Strangulated inguinal hernia due to an omental band adhesion within the hernial sac: a case report.

INTRODUCTION

Strangulated Inguinal hernia is one of the most common surgical emergencies dealt with by surgeons worldwide. Usually the narrow internal inguinal ring or the external inguinal ring is the site of constriction of the viscus, which forms the content of the hernia resulting in strangulation. We report a rare case of strangulated inguinal hernia where the constricting element is not the internal or external inguinal ring, but an omental band adhesion causing closed loop small bowel obstruction and gangrene within the hernial sac in the inguinal canal.

CASE REPORT

A 56-year-old Caucasian gentleman presented to us with a 6 hours history of non-reducible tender lump in his right groin. His groin was explored urgently under general anaesthesia and was found to have an omental band adhesion causing closed loop small bowel obstruction with gangrene within the hernial sac in the inguinal canal with a wide internal inguinal ring. Gangrenous small bowel was resected and primary anastomosis was performed through the same inguinal incision.

CONCLUSION

Strangulation of the inguinal hernial content is usually due to the tight constriction at the level of internal inguinal ring or at external inguinal ring. Uncommonly strangulation of the contents can occur due to other causes like omental band adhesion. Anyone presenting with clinical features of strangulated inguinal hernia with small bowel obstruction mandates prompt exploration of the inguinal canal. Although it may not change the treatment approach, one should be aware about this special entity. Resection of the gangrenous small bowel and primary anastomosis can be safely performed through the same inguinal incision.
