Abstract
A 73-year-old man underwent colonoscopy because of the positive fecal occult blood test, and was pointed out having a type 2 tumor in the sigmoid colon. The result of biopsy was well differentiated adenocarcinoma, and he was referred to our department for the purpose of operation. Abdominal plain X-ray showed calcifications in the right lateral region of abdomen. These calcifications were suspected to be stones in a Meckel's diverticulum by abdominal computed tomography. At the operation, we found a diverticulum projecting from the antimesenteric side which was located at 140cm proximal to the terminal ileum. We diagnosed it as Meckel's diverticulum with stones and performed sigmoidectomy and diverticulectomy at the same time. It contained multiple black enteroliths, 3 cm in diameter for each, and an analysis of them revealed to be composed of calcium oxalate.
Meckel's diverticulum with enterolith is rare, often presents with acute abdomen due to diverticulitis or perforation, and demands emergency operation. We report this rare case of silent Meckel's diverticulum with enterolith, with some discussion of the literature.
