Laparoscopic port Littre's hernia: a rare complication of Meckel's diverticulum.

Meckel’s diverticulum is a remnant of the proximal portion of the omphalo-mesenteric duct, which links the embryonic intestine with the umbilical bladder until the fifth week of gestation. The incidence of Meckel’s diverticulum is 2-3% and normally it is not symptomatic. Only 4-6% of cases will produce symptoms (more frequent during infancy), the principal manifestation being rectal bleeding, sometimes massive, due to the presence of gastric mucosa. Obstruction, intussusception and, more rarely, diverticulum to bladder fistulae and tumours may occur. Littré’s hernia is caused by the protrusion of Meckel’s diverticulum through an orifice in the abdominal wall. The incidence of Littré’s hernia is very rare and not many cases are found in the literature.
