Clinically, incisional hernias present as a bulge or protrusion at or near the area of a surgical incision. Virtually any prior abdominal operation can develop an incisional hernia at the scar area (provided adequate healing does not occur due to infection), including large abdominal procedures such as intestinal or vascular surgery, and small incisions, such as appendix removal or abdominal ...
An umbilical hernia is a health condition where the abdominal wall behind the navel is damaged. It may cause the navel to bulge outwards—the bulge consisting of abdominal fat from the greater omentum or occasionally parts of the small intestine. The bulge can often be pressed back through the hole in the abdominal wall, and may "pop out" when ...

A Spigelian hernia is the type of ventral hernia that occurs through the Spigelian aponeurosis, which is the part of the aponeurosis of the transverse abdominal muscle bounded by the linea semilunaris (or Spigelian line) laterally and the lateral edge of the rectus abdominis muscle medially.

A paraumbilical (or umbilical) hernia is a hole in the connective tissue of the abdominal wall in the midline with close approximation to the umbilicus. If the hole is large enough there can be protrusion of the abdominal contents, including omental fat and/or bowel .
Double indirect hernia: an indirect inguinal hernia with two hernia sacs, without a concomitant direct hernia component (as seen in a pantaloon hernia). [26] Hiatus hernia: a hernia due to "short oesophagus" — insufficient elongation — stomach is displaced into the thorax; Littre's hernia: a hernia involving a Meckel's diverticulum.
Internal hernias occur when there is protrusion of an internal organ into a retroperitoneal fossa or a foramen (congenital or acquired) in the abdominal cavity.If a loop of bowel passes through the mesenteric defect, that loop is at risk for incarceration, strangulation, or for becoming the lead point of a small bowel obstruction.

An epigastric hernia is a type of hernia that causes fat to push through a weakened area in the walls of the abdomen. It may develop in the epigastrium (upper, central part of the abdomen ). Epigastric hernias are more common in adults and usually appear above the umbilical region of the abdomen.
