An inguinal hernia or groin hernia is a hernia (protrusion) of abdominal cavity contents through the inguinal canal. Symptoms, which may include pain or discomfort especially with or following coughing, exercise, or bowel movements , are absent in about a third of patients.
Although women account for roughly 70% of femoral hernia repairs, indirect inguinal hernias are still the most common subtype of groin hernia in both males and females. [14] Inguinal hernia surgery is also one of the most common surgical procedures, with an estimated incidence of 0.8-2% and increasing up to 20% in preterm children. [15] [16]
An indirect inguinal hernia and a direct inguinal hernia can be distinguished by their positioning in relation to the inferior epigastric vessels. An indirect hernia is situated laterally to these vessels, whereas a direct hernia is positioned medially to them. Inguinal hernias are the most common type of hernia in both men and women.
Post herniorrhaphy pain syndrome, or inguinodynia is pain or discomfort lasting greater than 3 months after surgery of inguinal hernia. Randomized trials of laparoscopic vs open inguinal hernia repair have demonstrated similar recurrence rates with the use of mesh and have identified that chronic groin pain (>10%) surpasses recurrence (<2%) and is an important measure of success.
Internal hernias occur when there is protrusion of an internal organ into a retroperitoneal fossa or a foramen (congenital or acquired) in the abdominal cavity. If a loop of bowel passes through the mesenteric defect, that loop is at risk for incarceration , strangulation , or for becoming the lead point of a small bowel obstruction . [ 1 ]
Left and right inguinal regions shown in lower part of diagram. In human anatomy, the groin, also known as the inguinal region or iliac region, [1] is the junctional area between the torso and the thigh. [2] The groin is at the front of the body on either side of the pubic tubercle, where the lower part of the abdominal wall meets the thigh.
A hernia that exits the abdominal cavity directly through the deep layers of the abdominal wall, thereby bypassing the inguinal canal, is known as a direct inguinal hernia. In males with strong presentation of the cremasteric reflex , the testes can—during supine sexual activity or manual manipulation—partially or fully retract into the ...
A Richter's hernia can result in strangulation and necrosis in the absence of intestinal obstruction. It is a relatively rare but dangerous type of hernia. [1] Richter's hernia have also been noted in laparoscopic port-sites, usually when the fascia is not closed for ports larger than 10mm.
