Efficacy evaluation of different conservative treatments for blunt spleen rupture

This study aimed to provide a reference for the clinical treatment of patients with spleen ruptures by analyzing and discussing the clinical effects of the conservative treatment.

The clinical data of 93 patients with blunt spleen rupture treated in the First Affiliated Hospital of University of Science and Technology of China from April 2015 to April 2018 were retrospectively analyzed. Among them, 84 cases were treated conservatively and 9 cases were treated surgically. The general information of conservative treatment and surgical treatment were compared. The relationship between different conservative treatment methods and CT classification of spleen rupture and the changes of abdominal drainage were analyzed.

The CT classification grade and trauma score of patients with spleen rupture in surgical treatment were higher than those in conservative treatment group (P<0.05). A total of 90.3% patients were treated conservatively. Among them, 7.1% (83.4% were in CT classification of spleen injury grade 1-2) were from the observation group, 14.3% (83.3% were in CT classification of spleen injury grade 1-2) were from abdominal drainage group, 3.6% were from splenic artery embolization group, and 75% (9.5% were in CT classification of spleen injury grade 2, 77.8% in grade 3 and 12.7% in grade 4) were from splenic artery embolization plus abdominal drainage group. There was no significant difference in the total amount of abdominal drainage on day 1, day 2 and day 3, and the CT classification of spleen rupture (P>0.05). However, there significant differences on the amount of abdominal drainage among day 1, day 2 and day 3 (P<0.05). Meanwhile, 2 complications occurred in the splenic artery embolization plus abdominal drainage group.

Conservative treatment is feasible in blunt spleen rupture patients of CT classification grade of 1-4 with stable hemodynamical. Splenic rupture patients of CT classification grade 4-5 with instable hemodynamical should be treated surgically.
