Joe Y1 - 2019 N1 - T2 - Maingot's Abdominal Operations, 13e AB - The term hernia is used to describe a weakness or defect of the abdominal wall, through which abdominal contents can protrude. It is important to note the distinction between the hernia defect and hernia contents, as surgical repair is generally more concerned with the former, with a few exceptions. Abdominal wall defects arise at areas of weakness in the abdominal wall. These areas include sites of previous surgery, the umbilicus, as well as areas of weakened abdominal and/or flank musculature such as in lumbar hernias.1 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/20 UR - accesssurgery.mhmedical.com/content.aspx?aid=1160038215 ER -
