IntroductionThe Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract present in approximately 1-4% of the population; the MD duplication is exceedingly rare with only a few reports of it. Here we present the firs case of a strangulated Littre's hernia with MD duplication.Presentation of caseA 30-year-old male presented to the emergency room with clinical signs of small bowel obstruction, at physical examination, a right incarcerated inguinal hernia with erythema was found. We did a laparotomy, and two MD were found, one in the sac with ischemia, and the other 90 cm from the Bahuińs valve. A diverticulectomy of the ischemic diverticulum was done, and the other MD was left in place; the inguinal region was repaired with a Lichtenstein technique.DiscussionThe complications of the MD are 3-4 times more frequent in men, been an intestinal obstruction, hemorrhage, diverticulitis, ulceration, and perforation. A Littrés hernia is when the MD is found in the sac; this is seen in the inguinal region in 50% of the cases. The management of a Littre's hernia is the resection of the MD; it could be done by an intestinal resection or by a diverticulectomy accordingly to the Park criteria.ConclusionAs to our knowledge, this is the first case of an incarcerated Littre's hernia with duplication of a Meckel's diverticulum.
