Predisposing conditions in adults include ascites and prior abdominal surgery. The size of the defect determines the symptomatology and incidence of incarceration, with smaller defects resulting in more pronounced symptoms and an increased incidence of incarceration. Pain is located in the area of the fascial defect. Contents of the hernia may be palpable and tender. Symptoms of obstruction (nausea, vomiting, and abdominal distention) may be present. If the hernia becomes strangulated, erythema of the overlying skin with fever and hypotension may occur.
