A hernia is a protrusion, bulge, or projection of an organ or part of an organ through the body wall that normally contains it, such as the abdominal wall. They are typically classified by etiology and location. Most abdominal wall hernias should be repaired when identified; however, there are exceptions (eg, parastomal hernia). The nature of the repair depends upon the size of the hernia and the location on the abdominal wall in which it has occurred.
An overview of the classification, clinical features, and treatment options for most abdominal wall hernias will be reviewed here. More in-depth information for incisional hernias, inguinal and femoral hernias, parastomal hernias, and hernias related to peritoneal dialysis are discussed separately.
