Adult intussusception associated with mesenteric Meckel’s diverticulum and antimesenteric ileal polyp

Abstract

Meckel’s diverticulum is the most common congenital abnormality affecting the gastrointestinal tract, affecting 4% of the general population. It is classically located on the antimesenteric border of the ileum within 100 cm of the ileocaecal valve. Complications may include haemorrhage, bowel obstruction, diverticulitis, perforation and malignancy. This report explores the case of intussusception in an adult, in association with a mesenteric Meckel’s diverticulum and adjacent benign polyp. A 40-year-old man presented with acute abdominal pain, affecting the central abdomen and both flanks. CT imaging revealed small bowel intussusception, with either a Meckel’s diverticulum or polyp acting as a lead point. Intraoperatively, the intussusception had already resolved; however, an inflamed outpouching was identified on the mesenteric border of the ileum, with a firm mass palpable within the bowel lumen. A 70 mm small bowel resection and primary anastomosis were performed. Histopathological analysis confirmed an inflamed Meckel’s diverticulum as well as an adjacent diverticulum comprising a benign polyp.

Intestinal intussusception of Meckel’s diverticulum, a case report and literature review of the last five years

“…Two patients were less than 6 months of age, ( 6 , 10 ) three between 1 and 6 years of age, ( 14 , 16 , 17 ) five between 15 and 30 years of age ( 5 , 7 , 13 , 18 , 19 ) and five between 40 and 50 years of age. ( 8 , 9 , 11 , 12 , 15 )…”

“…From a geographical perspective, we observed that 15 publications came from five continents. One was from America (United States), (5) four from Europe (Italy, (6) France, (7) Spain (8) and the United Kingdom), (9) one from Africa (Tunisia), (10) seven from Asia (Japan, (11)(12)(13)(14) South Korea, (15) China (16) and Syria) (17) and two from Oceania (Australia). (18,19) Regarding the age of the patients included in this sample, there was a range from newborns to 49 years of age.…”

Torsed gangrenous Meckel’s diverticulum presenting as acute abdomen

“…It was first described by John Fredrich Meckel in 1809, hence given the name Meckel's diverticulum. [3] The possible common complications associated with it include hemorrhage, obstruction, diverticulitis, hernia, and inflammation. [4] Rarely, Meckel's diverticulum can also cause intussusception.…”
