A 78-year-old Japanese man who had been admitted to our hospital presented with sudden nausea, and upper abdominal pain. There was no abdominal surgical history. Abdominal CT revealed the dilatation of the small bowel and caliber change in the ileum. We diagnosed his condition as an intestinal obstruction in the ileum, and although we performed intestinal decompression using a transnasal ileus tube, it was not effective. Finally, we performed a laparotomy to resolve the intestinal obstruction. Intraoperative finding showed an intestinal obstruction entrapped between the mesodiverticular band (MB) of Meckel’s diverticulum and the ventral mesentery. We resolved the intestinal obstruction with the MB. Furthermore, we simultaneously resected Meckel’s diverticulum. There was no evidence of necrosis. The resected specimen of the MB histologically contained the remnant of the vitelline vessels. A case of ileus obstruction caused by the MB of Meckel’s diverticulum with histological confirmation is extremely rare. We therefore report herein on a case of MB-related intestinal obstruction with histological confirmation and share this case as important evidence for further embryological understanding.
