The medical condition in which a fatty tissue or organ squeezes through a weak spot in a muscle or connective tissue. There are various types of hernia, namely, inguinal, femoral, umbilical, incisional and hiatal. Hernias occur when pressure is applied through a weakened fascia or muscle. This abnormal pressure could be applied by diarrhea, coughing, constipation, sneezing or lifting heavy objects without supporting the muscles in the abdomen. The diagnosis of a hernia involves a physical examination as well as imaging techniques such as X-rays and ultrasound. The most common treatment for hernias is through a hernia-repair surgery. If left untreated, the hernia might become strangulated and cause serious complications. Different approaches, evaluations, methodologies and management strategies of hernia have been included in this book. Its aim is to present researches that have transformed the research on this medical condition and aided its advancement. The book is appropriate for students seeking detailed information in this area as well as for experts.
