Don't want your butt to suffer, here are some types of butt abscess you should know about

In fact, for us, the most troubled part is our feet, followed by the buttocks. We sit on them every day, so we must take good care of them. So what are the common types of buttock abscesses?

1. Perianal subcutaneous abscess

It is the most superficial abscess, distributed under the skin of the anus, mostly on the posterior and bilateral sides. The infection route is the anal sinus and the skin of the anus. The lesions are mostly localized and rarely spread to the surrounding area. The internal opening is at the tooth line corresponding to the lesion. There is localized redness and swelling, obvious pain, but rarely fever.

2. Subfascial abscess

Located in front of the anus, mainly in men, it will extend to the base of the scrotum. The abscess in this area is divided into two layers, deep and shallow. The infection route is the anal sinus at the tooth line in front of the anus and the lacerated anal canal skin, so the inner opening is generally located here. If it is not treated in time after the onset of the disease, it will often spread to the scrotum. The clinical manifestations are the same as subcutaneous abscesses.

3. Abscess in the posterior anal space

Located behind the anus, it is divided into two layers, deep and shallow. The shallow layer is connected to the perianal subcutaneous space. The deep layer leads to the ischiorectal pouches on both sides. The infection route is the anal sinus behind the tooth line and the fissure behind the anus. The internal opening is mostly at the posterior median tooth line. After the disease occurs, it is easy to spread to both sides. The pain is obvious, with or without fever, and obvious local redness and swelling.

4. Abscess of the sciatic rectal fossa

This is the largest abscess around the anus, one on each side, and connected through the deep space behind the anal canal. The infection route is basically the anal sinus, and there are two possible locations for the internal opening, one is the position corresponding to the lesion, and the other is the posterior median. The abscess on one side will spread to the opposite side, forming a horseshoe or semi-horseshoe-shaped abscess. The vast majority of complex anal fistulas originate from abscesses in this area. Redness, swelling, heat and pain are all obvious. The patient is restless and cannot eat, and is in great pain.

5. Abscess of the intersphincteric space

It refers to the area between the internal and external sphincters, and is the primary site of many perianal infections. As mentioned earlier, the anal sinus is the main entrance for bacteria to invade the anus, but the real entry into the anus depends on the anal glands, and most of the anal glands are located between the sphincters. Bacteria often infect here first, and then spread to other spaces. There is no definite location for its internal opening, but it is mostly located at the midline of the teeth, and the direction of spread is also uncertain. The pain is obvious, and the redness and swelling are not obvious in the early stage. The anus can be relaxed, and there is widespread tenderness.

6. Rectal submucosal abscess

It is a high-position abscess under the mucosa of the lower rectum, both front and back, left and right. The bacterial invasion route is the anal sinus. The lesions are mostly localized and rarely spread to the surrounding area. The internal opening and the lesions are in the same position. Fever is rare, and the main manifestations are distension and the feeling of defecation. The soft bulge at the lower end of the rectum can be felt by finger diagnosis.

7. Abscess of the retrorectal space

Located at the posterior side of the rectum, it is the highest position among all abscesses. The bacterial infection route is the anal sinus, and the internal opening is at the posterior median tooth line. After the disease occurs, it may spread to the pelvic rectal space on both sides, forming high-positioned horseshoe abscess and anal fistula, which is difficult to treat clinically. The pain is obvious or not obvious, bloating, urge to defecate, fever, a hard bulge can be felt at the posterior side of the rectum, and scar-like changes in the anal rectal ring.

8. Pelvic rectal fossa abscess

Located on both sides of the lower end of the rectum, one on each side, above the pelvic floor, below the peritoneum, and below the corresponding ischiorectal space, it is a high-position abscess. The infection route is the anal sinus, and the internal opening is mostly located at the posterior median tooth line. After the onset of the disease, it may spread to the opposite side through the posterior rectal space, or it may spread downward to the ischiorectal space. The manifestation is the same as the posterior rectal abscess, and a hard bulge can be felt on both sides of the lower end of the rectum.
