A hernia is the protrusion of an organ or the fascia of an organ through the wall of the cavity that normally contains it. A hiatal hernia occurs when the stomach protrudes into the mediastinum through the oesophageal opening in the diaphragm. This book presents topical research in the study of the types, symptoms and treatment of hernias. Topics discussed include minimally invasive repair of inguinal hernia in children; surgical approach to parastomal hernia and risk factors for incisional hernia after severe secondary peritonitis.
