When it comes to hernia, I believe that many people should be unaware of it. The so-called hernia is actually a human disease that most of us do not know about, and many people still suffer from hernia in their lives. In addition, there are many types of hernias, and perineal hernia is one of them, and it is also one of the more common ones. This is something that is not clear to the general public. As perineal hernia is strictly a private disease of the human body, many patients and friends should be embarrassed to talk about the specific symptoms of perineal hernia because the affected area is a private part of the human body. However, in order to cure perineal hernia as soon as possible, it is necessary to know the symptoms of perineal hernia. In this regard, the following are the common symptoms of perineal hernia. A perineal hernia is a prolapse of an intra-abdominal organ from the perineum through the muscle and fascia gap at the bottom of the pelvic cavity. The perineum is the entire soft tissue structure below the pelvic diaphragm that closes the pelvic outlet. The line of the sciatic tuberosity on both sides divides the perineum into 2 triangles: the anterior one is called the urogenital triangle, which is closed by the urogenital diaphragm and has the urethra in men and the urethra and vagina in women; the posterior one is called the anal triangle, which is closed by the pelvic diaphragm and has the rectum passing through. There is a weak point between the iliococcygeus and pubococcygeus muscles at the pelvic floor, and most hernias pass through this gap. Symptoms are divided into anterior perineal hernia and posterior perineal hernia according to the relationship of the hernia to the transverse perineal muscle. Anterior perineal hernia: An anterior perineal hernia is a protrusion of the hernia sac through the levator ani muscle and out of the urogenital diaphragm in front of the transverse perineal muscle. This hernia is seen almost exclusively in women and can be classified as a vaginal hernia, vaginal hernia, or labial hernia depending on where the hernia appears. The contents of the hernia can be the small intestine or sigmoid colon and usually part of the bladder. Almost all of them can be repositioned. Posterior perineal hernia: Posterior perineal hernia can occur in both men and women, but is much more common in women than in men. The hernia sac descends from the rectum to the bladder and appears in the colorectal fossa or in the perineum immediately above the mid-suture. In women, the hernia prolapses from the levator muscle fissure or between the levator and caudalis muscles, may appear in the sciatic rectal fossa, and may continue to extend inferiorly and expand at the inferior border of the gluteus maximus muscle. Therefore, it should be differentiated from a sciatic hernia. As seen above, the symptoms of perineal hernia can generally be divided into those of anterior and posterior perineal hernia. The symptoms of anterior perineal hernia are generally seen almost exclusively in female patients, while posterior perineal hernia can generally be manifested in both men and women.
