Abdominal hernias are one of the most common surgical problems. By definition, a hernia is an abnormal protrusion from one anatomic space to another, with the protruded parts generally contained in a saclike structure formed by the membrane that naturally lines the cavity. They are a one of the leading causes of morbidity and can be lethal.
Presentation
The hernia presents as a protrusion that gets bigger with increased intraabdominal pressure such as during coughing. They patient may present in an emergency situation with a strangulated hernia, or it may be found on routine examination. The protrusion may be intermittent or constant.
If strangulated, there is pain, swelling and erythema at the hernia site. There may be associated symptoms of intestinal obstruction like abdominal pain, vomiting and nausea. There may be peritonitis if the bowel gets gangrenous and perforates [7].
Entire Body System
- Inflammation
A strangulated hernia is one in which the circulation of blood through the hernia is impeded by pinching at the narrowest part of the passage; congestion is followed by inflammation, infection, and gangrene. [britannica.com]
A strangulated hernia is a surgical emergency because part of the bowel may become necrotic (dead), resulting in life-threatening peritonitis (inflammation of the abdominal cavity) needing surgical removal of part of the bowel. [jamanetwork.com]
Reduction should be avoided if there are signs of inflammation or strangulation. Usually all inguinal hernias should be repaired. Umbilical hernia repair should be carried out in adults. [symptoma.com]
Avoid consuming alcohol as it can cause gastrointestinal pain, bloating and inflammation. If you are exercising, make sure you are not doing it on a full stomach. Try not to lie down or bend over soon after eating. [braceability.com]
Respiratoric
- Chronic Cough
A case of traumatic abdominal hernia is reported in a patient with a history of chronic cough. After a bout of coughing 3 months prior to her presentation, the patient developed a large herniation on the left lateral side of the abdomen. [ncbi.nlm.nih.gov]
Persistently raised intra-abdominal pressure (e.g., due to ascites, pregnancy, intra-abdominal tumors, chronic cough, etc.) increases the risk of developing an abdominal hernia. [amboss.com]
These include heavy lifting, pregnancy or chronic coughing but can also result from injury or surgery. Treatment for ventral hernias consists of one of two types of surgeries: herniorrhaphy (open hernia repair) or laparoscopy (minimally invasive). [hopkinsmedicine.org]

- Pneumonia
More serious problems include heart attack, stroke, pneumonia, and blood clots in the legs. Getting out of bed after surgery and moving as soon as the doctor allows will help reduce the risk of complications such as pneumonia and blood clots. [herniacenter.surgery.ucsf.edu]
Walking boosts blood flow and helps prevent pneumonia and constipation. If your doctor gives you an abdominal binder to wear, use it as directed. This is an elastic bandage that wraps around your belly and upper hips. [myhealth.alberta.ca]
Increased activity reduces the risk of blood clots, and improves breathing to prevent pneumonia. Avoid lifting more than 10 pounds for 4 weeks and excessive bending or twisting for 1-2 weeks following surgery. [augusta.edu]

Laboratory diagnosis
There are no specific laboratory studies specific for hernia, but they may help in toxic patients.
Imaging
CT scan, ultrasound and radiographs are not usually required but may be used to confirm the diagnosis if there is doubt. The bulk of the diagnosis is clinical. In acquired hernias, workup of the underlying cause will have to be searched for, for example ascites [8].

Treatment
In adults most hernias should be repaired to prevent complications. Reduction should be avoided if there are signs of inflammation or strangulation. Usually all inguinal hernias should be repaired. Umbilical hernia repair should be carried out in adults. In children most will close by the age of five, unless they are large. Elective repair is preferred to acute repair. There are number of methods that can be used, for example the use of meshes and special suturing techniques.
Prognosis
This is dependent on the type of hernia present and its size and location. The largest risk is strangulation of intestines and if not repaired in time, it may lead to mortality rates as high as 10%. Uncomplicated hernias have a good prognosis if repaired appropriately [6].
Etiology
The congenital hernias are caused by small defects that occur during embryogenesis. Acquired hernias are caused by an increase in the abdominal cavity pressure that may weaken the wall and cause the protrusion. Risk factors for this include ascites, weight lifting, coughing, peritoneal dialysis and obesity [2] [3].
Epidemiology
As many as 10 to 13% of people will have a hernia at one time in their life. The most common hernia being inguinal taking up about 75% of all hernias of which 50% are indirect, 14% are umbilical, 10% are ventral and 3 to 5% femoral [4]. Inguinal hernias are more common in males, with 25% of males having one in their life time.
Pathophysiology
- Groin hernias are the commonest hernias of the abdominal wall. The inguinal hernia is caused by weakened musculature that usually causes a shutter effect during straining. Repeated straining that increases the intraabdominal pressure causes protrusion. Direct inguinal hernia is caused by weakness in the transversalis fascia area of the Hesselbach triangle. An indirect hernia follows the tract of the inguinal canal and it is caused by a persistent processus vaginalis.
- Epigastric hernias are located in the midline between the umbilicus and the xiphoid process and are usually >1cm. The cause of this may be a combination of congenital and acquired factors such as muscle weakens or increased intraabdominal pressure. These are usually asymptomatic and bowel strangulation is rare.
- Flank hernias, even being outside the anatomical abdominal wall, are still classified as such. There are two types, the superior and inferior triangle hernias. These can be acquired; usually after surgeries such as nephrectomies.
- Umbilical hernias in adults are usually acquired and associated with obesity, ascites, and pregnancy. This may present with strangulation of intestinal contents [5].
Prevention
There is no prevention of congenital hernias. Avoidance of chronic increased intraabdominal pressure is key. Thus patients with the risk factors for this should be treated promptly and appropriately [9] [10].
Summary
There are a number of different abdominal hernias and they are classified by their anatomical locations:
- Groin hernia is a hernia that occurs in the lower part of the abdomen where the thigh and the hip meets. There can be inguinal and femoral hernias.
- Pelvic hernias are protrusions through the foramina of the pelvis.
- Flank hernias protrude through weakened areas of back muscles. Included in this are the inferior and superior lumbar triangle hernias.
- Ventral hernias occur anteriorly, such as umbilical and epigastric hernias.
The hernias may also be classified as congenital such as an indirect inguinal hernia or acquired [1].
Patient Information
Definition
The internal organs are held in a cavity with a wall (abdominal). Defects in the wall may cause protrusion of the contents of the cavity. This causes a visible bulge in the defect. There many different types of abdominal wall hernias. The most common being inguinal hernia, which are more common in men. These occur around the groin area.
Cause
They are two types; defects in the wall that you are born with, so when the pressure in the abdomen increases the contents are pushed through this defect. The second are caused by having conditions that weaken the abdominal wall and increase the pressure within, like a chronic cough, or chronic straining while urination.
Symptoms
These may present as a bulge in the trunk of the body that increases in size on coughing or straining. The protrusion may balloon out into a sac that may hold intestines. The intestines may get jammed up in the sac and swollen and compressed. This is an emergency and can be fatal.
Diagnosis
Hernias are diagnosed by your doctor just by examination, the doctor may order some scans, but this is not routinely done.
Treatment
Hernias are repaired by surgery. There are two ways this may be done. Open surgery and laparoscopic or keyhole surgery. This will depend on the size and location of the hernia. They may also use meshes to strengthen the defect in the wall to prevent it coming back again.
