Amyand hernia
Updates to Article Attributes
Amyand hernia is a rare form of an inguinal hernia in which the vermiform appendix is located within the hernial sac. It is seen in less than 1% of inguinal hernia.
It should not be confused with an appendix-containing femoral hernia, known as De Garengeot hernia.
Terminology
The term applies to inguinal hernia containing appendix regardless of whether there are complications such as appendicitis5.
Clinical presentation
ClinicallyThe appendix may remain in an inguinal hernia without symptoms. If complications develop, an atypical presentation of acute appendicitis is expected, and the clinical presentationwhich may mimic incarcerated inguinal hernia.
Radiographic features
CT
- blind-ending tubular structure arising from caecum and extending into inguinal sac
- dilated lumen, wall enhancement and thickening, peri-appendiceal fat stranding are suggestive of acute appendicitis
Ultrasound
- extension of the appendix into the inguinal sac
- if acutely inflamed, the appendix is dilated, non-compressible, thickened and hypervascular
History and etymology
Claudius Amyand, was a French surgeon who performed the first successful appendectomy in 1735, on an 11-year-old boy who presented with an inflamed, perforated appendix in his inguinal hernia sac.
