Basic Facts About the Inguinal Canal

The inguinal canal of a human is a slanting passage that can be found at the lower anterior abdominal wall. Both males and females have this canal. Contents of inguinal canal are the testes of the men and the round and inguinal ligament of the uterus of women (to the labium majus). Aside from that, the canal is also the location of the ilioinguinal nerve. The inguinal canal can grow to about 1.5 inches in an adult human body. It runs from the deep inguinal canal ring, an oval fascia transversalis opening, toward a superficial inguinal canal ring, a triangular aponeurosis of the external oblique muscle, in a downward and medial fashion. The inguinal canal is located right above and parallel to the inguinal ligament.

Anatomy of the Inguinal Canal

Inguinal Canal

The boundaries of inguinal canal can be classified into four walls: the anterior, posterior, floor (or inferior wall), and roof (or superior). The anterior of the inguinal canal is formed by the aponeurosis of the external oblique muscle. The powered wall is formed by the whole length of the fascia transversalis. The floor is made up of the inguinal ligament, and the roof is formed by the combination of internal oblique fibers and transverses abdominal muscles.
Many people are not familiar with inguinal canal anatomy, although the condition “inguinal hernia” is one of the most common conditions that are treated by means of surgery. Inguinal pain is often an indication of inguinal hernia. There is an urgent need to correct hernia if it indeed occurs. To know more about this condition, read the next section.

What is an Inguinal Hernia?

Inguinal hernia occurs when contents of the abdomen or abdominal cavity passes through this canal. The condition is a common occurrence with a lifetime risk of 30% for men and 3% for women. Inguinal hernia treatment usually involves a surgical operation.

There are two types of hernia of the inguinal canal: direct inguinal hernia and indirect inguinal hernia. It is important to note that hernia more likely occurs in men because the inguinal canal in men has a larger opening and thus, a weaker wall where intestines can pass through, in comparison to the smaller inguinal canal of women.

If you notice any bumps in the lower part of your abdomen, any pain or discomfort that is associated with the bump, and/or tenderness in the area, you need to get yourself checked immediately to rule out hernia in your inguinal canal.

Noticeable Inguinal Hernia Symptoms

Inguinal hernia symptoms are a few of the things that people have to watch out for, especially in the case of adult men. Hernia occurs when any object within the abdominal cavity manages to enter the inguinal canal, causing a characteristic bulge on the lower abdominal area of the patient. Pain is not always a symptom that indicates hernia. However, these inguinal hernia symptoms are some things you need to watch out for:

• Bulges in the groin area that become more emphasized during straining, coughing, and standing erect.
• A bulge that disappears when you lie down
• Significant inguinal pain may suggest an indirect inguinal hernia caused by a strangulated bowel (Direct inguinal hernia occurs when an intestine manages to protrude into the inguinal canal).

Inguinal Hernia Symptoms

Apart from these symptoms, the following can also help conclude if the patient is suffering from hernia:

• Epididymitis
• Testicular torsion
• Hydrocele
• Varicocele
• Lipomas
• Inguinal adenopathy, among others.

Inguinal Hernia Symptoms and Treatment

Usage of the hernia truss was common in the late 80s and 90s, until hernia surgery became more efficient and convenient. Inguinal hernia surgery, or more commonly known as hernia repair, is an outpatient surgery intended to correct and/or alleviate the occurrence of hernia in a patient. It has numerous types, depending on the mode of entry, kind of anesthesia used, type of bilateral repair chosen, etc.

Inguinal Hernia Recovery

The most difficult part about recovering from an inguinal canal surgery is when a patient is confronted with the need to move bowels, strain, and even to cough, in fear that the sutures may be displaced. However, most surgical operations done to treat hernia actually require the patient to strain and cough to check if the corrective procedure is effective in keeping the unwanted objects out of the inguinal canal.

In the post-operative phase of hernia surgery, the patient should be able to manage coughing and straining properly. To aid in bowel movements (which can be aggravated by patient stress and constipation caused by side-effects), a high-fiber diet is encouraged.

Many people have a fear of checking if they experience inguinal hernia symptoms. However, what you should fear is the complications that hernia can bring if you decide to neglect any tell-tale signs of the medical condition. The inguinal canal is a very important and sensitive area in your groin that needs to be checked regularly. If you want to stay healthy and keep away from the operating table as much as possible, watch out for inguinal hernia symptoms so you can treat hernia more easily.
