Parastomal Hernias and Others-Incidence
An incisional hernia may develop after any surgical procedure requiring surgical “incisions”. A parastomal hernia surfaces around the stoma and may follow any surgery for colostomy, ileostomy, or urinary diversion. There is debate concerning the incidence of parastomal and incisional hernias, but it is supposed to range between 20-30% of total interventions. The success rate for surgical repair in both types of hernia is quite low as the recurrence rate stands close to 50%.
Regarding solely parastomal hernias, studies show that they are a rather common occurrence during the first years subsequent to ileostomy or colostomy surgery. The incidence of parastomal herniation is approximately up to 48% on end-colostomies, 31% on loop-colostomies, 40% on ileostomies, and 28% on loop-ileostomies.
What may cause a Parastomal or an Incisional Hernia?
There are some situations that make a person susceptible to developing a hernia: surgeries that take intestine around and not through the rectus abdominus muscle (which helps to hold the stoma); instances that weaken the abdominal wall such as obesity, malnutrition, corticosteroid use, wound infection, and age; undue intra-abdominal pressure from lifting objects or chronic coughing; and presence of conditions such as diabetes, and lung disease.
How to prevent a Parastomal or an Incisional Hernia?
In general, optimal surgical approach (you need a good surgeon!), good physical condition, orderly life, and wearing an ostomy support or hernia belt are major factors preempting incisional and parastomal hernias.
