Parastomal hernia (PSH) is a type of incisional hernia defined as a protrusion of abdominal contents through a weakness in the abdominal wall. PSH is the most common and significant complication following enterostomy construction, with an incidence of 30–50%. The risk is higher in colostomies than in ileostomies. Diagnosis of PSH is based on clinical examination or imaging. Most patients with PSH are usually asymptomatic. On the other hand, PSHs may affect an individual’s physical function and decrease their quality of life. Surgical repair is indicated in 10–30% of patients with PSH. For repair, no single technique is superior to another. Therefore, several surgical methods have been developed and attempted, including primary repair, stoma relocation, and repair with different types of mesh either via the open or laparoscopic approach. However, high recurrence rates have been reported after repair. Because this is a difficult and problematic entity, the prevention of PSH occurrence is clearly the most appropriate management approach.
