Q&A Inguinal hernia(rupture)
What’s Inguinal hernia?
Inguinal hernia is what has been referred to as rupture. And the boundary part of abdomen and thighs is called Inguinal region.
In case of men, blood vessel and fascicle of seminal ducts connecting to the testis(testicle) are connected from inside the stomach to its outside through a gap in muscle of inguinal region. And in case of women, the ligament which supports the womb passes through the gap.

When the membrane(membranes of the abdomen) covering the inward organs is popped out into the gap in muscle of inguinal region, just like a finger cot, it is called Inguinal hernia and into where, bowels and greater omentum (like lumps of fat inside the stomach) pop out. There are cases where crural hernia is developed in women who have delivered many babies.
What causes Inguinal hernia?
Please imagine a water-filled balloon in a pot. If there is a hole on the bottom of the pot, a part of balloon comes out through it.
It may become easier to grasp the image of Inguinal hernia if you think the hard pot is muscle, the balloon is membranes of the abdomen, and the water inside the balloon is inward organs.
There are 2 kinds of Inguinal hernia; “external inguinal hernia” which membranes of the abdomen pop out through the spermatic cord and “internal inguinal hernia” which is developed in the region more inside and downward than the former.
What would happen if Inguinal hernia were left untreated?
If inguinal hernia were left untreated, internal organ would be squeezed by muscle making it unable to return to where it was originally positioned. This is called incarcerated hernia. The risk of the development is said to be roughly 10% of total.
Once the bowels have developed incarcerated hernia, it blocks food from flowing into the bowels, leading to intestinal blockage.
It can be life-threatening too, as blood stops flowing into squeezed bowels, it eventually kills the tissues of bowels(necrosis) and leads to blood poisoning.
This incarcerated hernia can happen anytime and no one can predict it coming. When it is developed, there is a need for emergency surgery. When necrosis of the bowels is developed, it may require resection and there is even a case where creation of an artificial anus becomes necessary.
What treatment approaches are there for Inguinal hernia?
We have no choice but to perform surgery in case of Inguinal hernia. It can’t be cured by drug treatment, truss, or muscle training. It puts least burden on patients financially and physically and also safe, to receive treatment before Inguinal hernia develops.
What kind of surgery is required?
What kind of surgery is required? In the past, the surgery was performed to pull up the gap between the muscles and stitched them. This method required a long rest after the surgery as there was postoperative pain and had a 10% of relapse rate. However, There were still people who experienced recurrence. Today, a surgery which fulfills the gap between the muscles with mesh made of synthetic fiber(polypropylene) is performed. The feature of this method is that, there is less pain and the relapse rate is extremely low.
There are various kinds of surgical procedures but in our hospital, we perform surgery following Lichtenstein/ Kugel methods.
As for hernia in children, tying the hernia sac at its root(high ligation) is enough as their muscles develop as they grow older.

Surgery(inguinal hernia) is left untreated, internal organ becomes squeezed by muscle, making it unable to return to where it was originally positioned. This is called incarcerated hernia. The risk of developing it is said to be roughly 10% of total. Once incarcerated hernia has developed in the bowls, it blocks food from flowing into the bowels, leading to intestinal blockage. It can be life-threatening too, as blood stops flowing into squeezed bowels, it eventually kills the tissues of bowels(necrosis) and leads to blood poisoning.
This incarcerated hernia can happen anytime and no one can predict it coming. When it is developed, there is a need for emergency surgery. When necrosis of the bowels is developed, it may require resection and there is even a case where creation of an artificial anus becomes necessary.
