This disease will develop from an infection that will be found in the crypto glandular epithelium that will line up with the anal canal. As a barrier for infection will serve the internal anal sphincter, never allowing any kind of parasites to pass on, from the gut lumen up to the deep perirectal tissues. This type of barrier can be passed with the help of the crypts of Morgagni that will penetrate the internal sphincter into the intersphicteric space.
If any type of infection will reach the intersphicteric space, it will have easy access to the all adjacent perirectal spaces. The extension of the infection will solely depend on its severity and type and at the very same time if can involve ischiorectal space or even the elevated space.
This kind of disease can have its peak in the forth decade of life, men being more affected than women having a predominance of 2:1 and 3:1. Almost 40% of the patients that will suffer from anorectal abscesses will have it their medical history similar abscesses that can be linked to some surgical interventions or in some cases to spontaneous apparition.
Also studies have shown that there is a higher incidence within the spring and summer seasons in comparison with the fall and winter seasons, some claiming that it can be linked with several specific severe allergies. While scientist cleared the demographics, they cannot put a mental map on this type of disease, being common in any types of the world and having no specific background on environment or weather conditions.
There is a direct link between the formation of the anorectal abscesses and the bowel habits but at the same time no proof has been made between the poor personal hygiene and the development of such a condition. In infants the occurrence of such a disease is most uncommon although there have been cases where the child contracted it due to a very unhealthy eating habit but fortunately in children, this condition will be in the majority of cases proven to be benign and rarely will require some operative intervention.
There are two types of treatment for perianal abscess and it will solely depend on the gravity and the stage of the condition will present itself. Some adjuvant medical therapy will be in the form of antibiotics and other types of drugs due to the non responsive outcome of the patient when they also suffer from diabetes for example.
The second type of treatment will be surgical therapy that will include surgical drainage of all the purulent collection if primary antibiotic therapy proves to be ineffective.
