- after abdominal surgery, the site of repair will always be structurally weaker. Sometimes, the intestines can push through the closed incision, causing a hernia. This occurs after 2-10% of all abdominal surgeries, although people with Diabetes are more at risk. After surgical repair, incisional hernias have a high rate of returning (20-45%).
This rare hernia occurs along the edge of a midline muscle called the rectus abdominus. The bulge is seen several inches to the side of the middle of the abdomen.
This extremely rare abdominal hernia happens mostly in women. This hernia protrudes from the pelvic cavity through an opening in the pelvic bone (Obturator foramen). This will not show any bulge but can cause bowel obstruction Epigastric hernia:
Occurring between the navel and the lower part of the rib cage in the midline of the abdomen, epigastric hernias are composed usually of fatty tissue and rarely contain intestine. Formed in an area of relative weakness of the abdominal wall, these hernias are often painless.
