It is estimated that about 1 in 4 adults with Crohns disease will develop an abscess or fistula during their lifetime. An abscess is a tender mass that is caused by a collection of pus that has accumulated in a cavity formed by tissue. For people with Crohn's Disease, the terminal ileum is the most likely area for abscesses and occurs in 1520% of patients.[1]



Abdominal pain and tenderness
Abdominal mass
Leukocytosis (elevated white blood cell count)
Pain when defecating, walking, or sitting when the abscess is around the anus.

Perianal Abscesses

A perianal abscess is an abscess located near the anus. The pain may be worsened when defecating, walking, or sitting and it is not uncommon for these abscesses to turn into fistulae. Sitz baths can be very beneficial.


Various tests used to diagnose abscesses include Computed Tomography (CT Scan), barium enema, and ultrasonography.


As a general rule the only way to effectively treat an abscess is to have it drained. This is either done percutaneously with a needle inserted through the skin, which is guided to the correct location with the help of a CT scanner, ultrasound, or surgically. A broad spectrum antibiotic is often given as well. At times, resection of the affected portion of the intestine is necessary.

Sometimes your physician will suggest Sitz Bath with certain salt additives. *Consult your physician before starting any treatment or therapy including Sitz Baths
