[Purpose] This study aimed to determine the characteristics of internal organ injuries in the abdomen and pelvis. [Subjects/Methods] The analysis included 27,877 patients who were registered in the Japan Trauma Data Bank between 2004 and 2019. All patients had abdominal and pelvic internal organ injuries with an abbreviated injury scale (AIS) severity score of ≥ 2. The number of patients, mechanism of injury, prognoses, and concurrent injuries are described. [Results] The majority of the cases involved parenchymal organ injuries due to blunt trauma such as vehicle crashes and falls. The proportion of younger patients was higher for parenchymal organ injuries than luminal organ injuries. The proportion of penetrating injuries was higher in luminal organ injuries than in parenchymal organ injuries. More than 100 cases involved major organ injuries. Patients with colon and rectal injuries had the highest in-hospital mortality rate, and patients with bladder injuries had the lowest in-hospital mortality rate. Concurrent injuries were observed in the neighboring body regions or organs. [Conclusion] This study documented specific characteristics and anatomical features of internal organ injuries in the abdomen and pelvis, which may provide useful cues for diagnosis and treatment planning.
