What is a colostomy?

A colostomy (referred to as stoma) is a piece of colon that is brought through the skin to provide the body with an alternative way to eliminate the waste of digestion.  Patients with medical conditions such as inflammatory bowel disease, colorectal cancer, or emergency bowel surgery can require colostomy as part of their treatment.  Its main purpose is to divert the fecal stream.  For some patients a colostomy is used as a permanent treatment but for some it is a temporary measure which is reversed at a later phase.  There are 2 types of colostomy: end colostomy [Figure 1] and loop colostomy [Figure 2].

Post-operative care

When a colostomy is in place, the stool comes out through it instead of the anus.  In most patients, the output from a colostomy is formed and similar in consistency to stool.  If a colostomy is created using the ascending or transverse colon, the output can be softer and more liquid in the early recovery period [Figure 3].  Ensuring a proper fit of the appliance to collect the waste is an important part of your care.  Failure to properly care for your stoma on a daily basis can lead to skin irritation.  While a colostomy is a life changing event, the majority of patients learn how to effectively manage their stoma and after a period of psychological and physical adaptation they can lead successful and productive lives.
