    Author: Ma P, Cao Y, Gao F, Qiao Z.
    Journal: Rev Esp Enferm Dig; 2022 Oct; 114(10):624. PubMed ID: 35410482.
    Abstract:
    A 25-year-old woman visited our department due to intermittent defecation of black stool and periumbilical pain for 2 years. Abdominal physical examination showed no obvious abnormality. Laboratory examination showed positive fecal occult blood. Because bleeding lesions were not found by gastroscopy or colonoscopy, she underwent double-balloon enteroscopy examination. It was found that a diverticulum was formed in the terminal ileum, with blood exudation. After repeated washing, the blood disappeared. However, after a period of time, blood exudation could still be detected there. She was diagnosed as Meckel's diverticulum with hemorrhage. Considering the patient's repeated gastrointestinal bleeding, surgical treatment was performed. Surgical specimens showed a 2.5×2.3×1.5 cm3 intestinal diverticulum with a soft texture, and the mucosa was grayish white. Postoperative pathological showed ectopic gastric mucosa with chronic inflammatory cell infiltration. The diverticulum had been found to contain gastric fundus gland tissues which were mainly composed of parietal cells and main cells. The patient recovered well after operation.
