Feb 4, 2025 · Internal hernias are characterized by internal organs, often intestinal bowel loops, protruding through the abdominal tissue wall. This is caused by a weakness of an abdominal structure, often as a result of either a birth defect, injury, inflammation, or surgery.

Jan 2, 2025 · Internal hernias (alternative plural: herniae) are protrusions of the viscera through the peritoneum or mesentery but remaining within the abdominal cavity. Internal hernias have a low incidence of <1% and represent a relatively small proportion, up to 5.8%, of presentations with small bowel obstruction 1.

An internal hernia (IH) is defined as the protrusion of abdominal viscera, most commonly small bowel loops, through a peritoneal or mesenteric aperture into a compartment in the abdominal and pelvic cavity (1-3).

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. [1]

Internal Hernias are protrusions of viscera through the peritoneum (a serous membrane that covers the walls of the abdominal cavity and surrounds every organ in that area) towards another section of the abdominal cavity.

Mar 1, 2006 · Internal hernias, including paraduodenal (traditionally the most common), pericecal, foramen of Winslow, and intersigmoid hernias, account for approximately 0.5-5.8% of all cases of intestinal obstruction and are associated with a high mortality rate, exceeding 50% in some series.

Internal hernias occur when organs or tissues within the abdominal cavity protrude through a defect or opening in the abdominal wall. The main causes of internal hernias include congenital defects, post-surgical complications, abdominal trauma, and anatomical variations.

We report a case of internal hernia in a 61-year-old male of Japanese ethnicity. The patient had advanced sigmoid colon cancer, early-stage transverse colon cancer, and multiple adenomatous polyposis, and underwent laparoscopically-assisted subtotal colectomy.

A hernia occurs when part of your insides bulges through an opening or weakness in the muscle or tissue that contains it. Most hernias involve one of your abdominal organs pushing through one of the walls of your abdominal cavity. Hernias can occur gradually as you get older and regular wear and tear on your muscles begins to add up.

We review the main mechanisms of internal abdominal herniations and the main radiologic findings on barium as well as CT studies. The classifications of internal abdominal herniations devised by Ghahremani [5] is now well accepted.
