The splenic surface can be anatomically divided into the visceral surface connected to major blood vessels and the diaphragmatic surface attached to the diaphragm. This study aimed to investigate differences in future treatment and outcomes according to the anatomical location of splenic injuries following abdominal trauma. Patients who were treated at a single trauma center between January 2011 and April 2018 were included. The presence of lacerations or hematoma on the visceral surface was evaluated via computed tomography. Differences in the location of splenic surgery between a group that underwent surgical or radiologic intervention and a group that received conservative care only were analyzed. Of 355 patients with splenic injury analyzed, the total mortality rate was 15.2%. A total of 167 patients underwent surgery and angiographic embolization, and 168 received conservative care only. Splenic injuries involved the visceral surface in 127 and 105 patients in the respective groups. Significant differences in the incidence of splenic injuries involving the visceral surface were found between the two groups in the univariate and logistic regression analyses. The likelihood of needing surgery and treatments such as embolization was higher for cases of splenic injury involving the visceral surface than for splenic injuries that did not involve the visceral surface. Through additional research, it may become possible to analyze the location of a splenic injury to determine an effective and safe method of treatment and accurately predict a prognosis.
