    Author: Chen Y, Tang Y, Hu C, Chen S.
    Journal: J Comput Assist Tomogr; 2019; 43(2):220-227. PubMed ID: 30531229.
    Abstract:
    OBJECTIVE: The aim of this study was to evaluate the computed tomography enterography (CTE) characteristics of bleeding Meckel diverticulum. METHODS: The CTE images of 35 patients with Meckel diverticulum and gastrointestinal bleeding were retrospectively evaluated. RESULTS: Meckel diverticulum was visualized in 33 of 35 patients and located in the right lower abdomen (20/33), midline lower abdomen (8/33), left lower abdomen (3/33), or paramedially near the umbilicus (2/33). The Meckel diverticulum was visualized on the antimesenteric side of the ileum in 16 patients (48.5%) and pointed toward the umbilicus in 10 (30.3%). The diverticulum appeared as a blind-ended tubular (22/33 [66.7%]) or saccular (11/33 [33.3%]) bowel segment. Separated supplying vessel was identified in 15 patients (45.5%) and associated with diverticulum (P = 0.037). The ectopic tissue was pathologically confirmed in 11 (33.3%) of 33 patients and was associated with diverticular nodules (P = 0.002). CONCLUSIONS: Awareness of CTE features could aid in the preoperative assessment of bleeding Meckel diverticulum.
