Hernia, Abdominal
|
D046449 |
[A protrusion of abdominal structures through the retaining ABDOMINAL WALL. It involves two parts: an opening in the abdominal wall, and a hernia sac consisting of PERITONEUM and abdominal contents. Abdominal hernias include groin hernia (HERNIA, FEMORAL; HERNIA, INGUINAL) and VENTRAL HERNIA.

Hernia, Diaphragmatic
|
D006548 |
[Protrusion of abdominal structures into the THORAX as a result of congenital or traumatic defects in the respiratory DIAPHRAGM.

|
Hernia, Diaphragmatic, Traumatic
|
D006549 |
[The type of DIAPHRAGMATIC HERNIA caused by TRAUMA or injury, usually to the ABDOMEN.
] |
|
Hernia, Femoral
|
D006550 |
[A groin hernia occurring inferior to the inguinal ligament and medial to the FEMORAL VEIN and FEMORAL ARTERY. The femoral hernia sac has a small neck but may enlarge considerably when it enters the subcutaneous tissue of the thigh. It is caused by defects in the ABDOMINAL WALL.

|
Hernia, Hiatal
|
D006551 |
[The most common kind of HIATAL HERNIA in which the ESOPHAGOGASTRIC JUNCTION slides above the DIAPHRAGM into the THORAX.
, STOMACH herniation located at or near the diaphragmatic opening for the ESOPHAGUS, the esophageal hiatus.
, A HIATAL HERNIA in which the STOMACH herniation is located alongside the ESOPHAGUS and the ESOPHAGOGASTRIC JUNCTION is in its normal position below the DIAPHRAGM.

|
Hernia, Inguinal
|
D006552 |
[An abdominal hernia with an external bulge in the GROIN region. It can be classified by the location of herniation. Indirect inguinal hernias occur through the internal inguinal ring. Direct inguinal hernias occur through defects in the ABDOMINAL WALL (transversalis fascia) in Hesselbach's triangle. The former type is commonly seen in children and young adults; the latter in adults.

|
Hernia, Obturator
|
D006553 |
[A pelvic hernia through the obturator foramen, a large aperture in the hip bone normally covered by a membrane. Obturator hernia can lead to intestinal incarceration and INTESTINAL OBSTRUCTION.
] |
|
Hernia, Umbilical
|
D006554 |
[A HERNIA due to an imperfect closure or weakness of the umbilical ring. It appears as a skin-covered protrusion at the UMBILICUS during crying, coughing, or straining. The hernia generally consists of OMENTUM or SMALL INTESTINE. The vast majority of umbilical hernias are congenital but can be acquired due to severe abdominal distention.
, A congenital defect with major fissure in the ABDOMINAL WALL at the UMBILICUS resulting in the extrusion of VISCERA through the UMBILICUS. Unlike GASTROSCHISIS, omphalocele is covered with PERITONEUM but without overlying SKIN.

|
Hernia, Ventral
|
D006555 |
[A hernia caused by weakness of the anterior ABDOMINAL WALL due to midline defects, previous incisions, or increased intra-abdominal pressure. Ventral hernias include UMBILICAL HERNIA, incisional, epigastric, and spigelian hernias.
] |
|
Hernias, Diaphragmatic, Congenital
|
D065630 |
[Protrusion of abdominal structures into the THORAX as a result of embryologic defects in the DIAPHRAGM often present in the neonatal period. It can be isolated, syndromic, nonsyndromic or be a part of chromosome abnormality. Associated pulmonary hypoplasia and PULMONARY HYPERTENSION can further complicate stabilization and surgical intervention.

Herniorrhaphy
|
D059685 |
[Surgical procedures undertaken to repair abnormal openings through which tissue or parts of organs can protrude or are already protruding.

Herpes Simplex
|
D006561 |
[A group of acute infections caused by herpes simplex virus type 1 or type 2 that is characterized by the development of one or more small fluid-filled vesicles with a raised erythematous base on the skin or mucous membrane. It occurs as a primary infection or recurs due to a reactivation of a latent infection. (Dorland, 27th ed.)
