Changes in the diagnosis and treatment of traumatic splenic rupture: a retrospective analysis of 99 consecutive cases.

From January 1986 to January 1995, 99 consecutive cases with a ruptured spleen were analysed retrospectively. Diagnostic peritoneal lavage was replaced by abdominal ultrasound as a routine screening investigation in blunt abdominal trauma after 1991. An abdominal computed tomography scan carried out in stable circulatory conditions provided additional information in 80% of the cases. The choice of treatment was related to the extent of the splenic damage and associated injuries. Even in degree IV ruptures splenorrhaphy was carried out successfully in 38% (five out of 12). The Hospital Trauma Index-Injury Severity Score (HTI-ISS) was significantly lower (17.7; n = 43) in conservative treatment than in cases treated by splenorrhaphy (27.6; n = 25) or splenectomy (33.6; n = 31). Conservative treatment (n = 43) resulted in a secondary intervention in 19%, whereas primary splenorrhaphy (n = 25) failed once (4%). Clinical morbidity was 26%, with no significant differences between conservative treatment, splenorrhaphy and splenectomy. Early mortality (0-30 days post-trauma) reached 14%, and was related to extensive injuries in all cases. The mean HTI-ISS in patients with a fatal outcome was 50.5. Overall, 62% of the injured spleens were saved, with the rate of splenic preservation improving throughout the study period. A conservative policy was increasingly treatment of first choice in patients with stable circulatory parameters with major concomitant injuries.
