A strangulated femoral hernia occurs when a constriction of the hernia limits or completely obstructs blood supply to part of the bowel involved in the hernia. Strangulation can occur in all hernias, but is more common in femoral and inguinal hernias due to their narrow "weaknesses" in the abdominal wall.
Groin hernias are most commonly inguinal hernias but may also be femoral hernias. [1] Other types of hernias include hiatus, incisional, and umbilical hernias. [6] Symptoms are present in about 66% of people with groin hernias. [1] This may include pain or discomfort in the lower abdomen, especially with coughing, exercise, or urinating or ...
Inguinal hernias, in turn, belong to groin hernias, which also includes femoral hernias. A femoral hernia is not via the inguinal canal, but via the femoral canal, which normally allows passage of the common femoral artery and vein from the pelvis to the leg. In Amyand's hernia, the content of the hernial sac is the appendix.
A Richter's hernia occurs when the antimesenteric wall of the intestine protrudes through a defect in the abdominal wall. This is distinct from other types of abdominal hernias in that only one intestinal wall protrudes through the defect, such that the lumen of the intestine is incompletely contained in the defect, while the rest remains in the peritoneal cavity.
An obturator hernia is a rare type of hernia, encompassing 0.07-1% of all hernias, [2] of the pelvic floor in which pelvic or abdominal contents protrudes through the obturator foramen. The obturator foramen is formed by a branch of the ischial (lower and back hip bone) as well as the pubic bone.
It can also pass medial to the femoral ring along the margin of the lacunar ligament (Figure B). In either case it would be at risk of injury during the operation to repair a femoral hernia, whether the hernia is reducible, incarcerated or strangulated. When the obturator artery travels along the lacunar ligament, it nearly encircles the ...
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 ]
The entrance to the femoral canal is the femoral ring, through which bowel can sometimes enter, causing a femoral hernia.Though femoral hernias are rare, their passage through the inflexible femoral ring puts them at particular risk of strangulation, giving them surgical priority.
