Amyand's hernia is a rare form of an inguinal hernia (less than 1% of inguinal hernias) [2] which occurs when the appendix is included in the hernial sac and becomes incarcerated. The condition is an eponymous disease named after a French surgeon , Claudius Amyand (1660–1740), [ 3 ] who performed the first successful appendectomy in 1735.
De Garengeot's hernia is a rare subtype of an incarcerated femoral hernia. This eponym may be used to describe the incarceration of the vermiform appendix within a femoral hernia . [ 1 ] This mechanism is contrasted with the Amyand hernia, in which the appendix protrudes through an inguinal hernia.
[5] "Incarcerated hernia is a hernia that cannot be reduced. These may lead to bowel obstruction but are not associated with vascular compromise." [6] A hernia can be described as reducible if the contents within the sac can be pushed back through the defect into the peritoneal cavity, whereas with an incarcerated hernia, the contents are stuck ...
Ultrasound showing an indirect inguinal hernia [18] Incarcerated inguinal hernia [19] An indirect inguinal hernia results from the failure of embryonic closure of the deep inguinal ring. In the male it can occur after the testicle has passed through the deep inguinal ring. It is the most common cause of groin hernia.
Groin hernia includes femoral, obturator, and inguinal. [1] Inguinal hernia is the most common type of hernia and consist of about 75% of all hernia surgery cases in the US. Inguinal hernia, which results from lower abdominal wall weakness or defect, [2] is more common among men with about 90% of total cases.
It is more often seen in men, and predominantly on the right side. Maydl's hernia should be suspected in patients with large incarcerated herniae and in patients with evidence of intra-abdominal strangulation or peritonitis. Postural or manual reduction of the hernia is contra-indicated as it may result in non-viable bowel being missed. [2]
By far the most common hernias (up to 75% of all abdominal hernias) are inguinal hernias, which are further divided into the more common indirect inguinal hernia (2/3, depicted here), in which the inguinal canal is entered via a congenital weakness at its entrance (the internal inguinal ring), and the direct inguinal hernia type (1/3), where ...
The inguinal ligament (/ ˈ ɪ ŋ ɡ w ɪ n ə l / [1] [2]), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop.
