Ladd bands

Ladd bands are the most commonly encountered form of peritoneal bands in disarrangement of intestines, e.g. intestinal malrotation.

Classically they extend from the abnormally positioned caecum to peritoneum and liver, crossing the duodenum in their course. Extension, however, can include further parts of the intestine.

Their relevance lies in predisposition to

  • intestinal obstruction by internal hernias or volvulus
  • intestinal infection within an extra compartment, e.g. fever of unknown origin

They are usually not visualized directly unless very extensive. Indirect visualization by small bowel pass through studies is possible. The intestinal malformation may be visualized by CT, pass through studies, US and MRI.

These "mesenteric attachments" were first described as a cause of congenital duodenal obstruction by American surgeon William E Ladd (1880-1967) in 1932 5. In this publication, he attributed disease to an embryologic failure of rotation. The surgical procedure for removal of these peritoneal bands is known as Ladd's procedure 4.

Ladd is considered a father of pediatric surgery, and co-founded the division of pediatric surgery at Boston Children's Hospital in 1910. Although most commonly remembered for his work investigating intestinal malrotation, Ladd also developed surgical treatment for pyloric stenosis and was the first to advocate use of contrast enema (originally bisthmus contrast) for diagnosis and treatment of intussusception 6.
