Amyand's hernia

Related people

An inguinal hernia with an appendix involved. In 1735 Amyand described the presence of a perforated appendix within the hernial sac of an 11-year-old boy who had undergone successful appendicectomy. The operation was performed on December 6, 1735, at St. george’s Hospital in London. The organ was perforated by a pin the boy had apparently swallowed. The patient, Hanvil Andersen, made a spectacular recovery and was discharged a month later.
