A review of non-operative treatment of splenic trauma

Conservative management of splenic injury in the tropics

We undertook this study in order to determine whether the conservative management of splenic injuries is a safe practice in a low-volume tropical hospital. We evaluated 69 consecutive patients with splenic injury prospectively. The outcome measures were morbidity and mortality rates, overall hospital stay and blood transfusion requirements. Spleen preservation was achieved in 85% (59) of cases. Of the 16 patients who underwent splenic surgery, six had splenorraphy (38%). The overall mortality was 4.3% (3) and the deaths were not related to the conservative management. Our findings suggest that not only is the conservative management of splenic injuries safe, but also that the repair of an enlarged spleen (splenorrhaphy) is safe and feasible in tropical hospital settings. The findings in this study provide further evidence that the conservative management of splenic injury in a tropical hospital without computed tomography scan is a safe practice.

Nonoperative management of the ruptured spleen: a revalidation of criteria

BACKGROUND

Our goal was to revalidate this institution's original criteria for safe nonoperative management of splenic injury.

METHODS

This was a prospective series between October 1991 and December 1995 entering all patients with splenic injury to a modified algorithm. Patients were taken to the operating room if hemodynamically unstable (systolic blood pressure less than 90 mm Hg; pulse greater than 110 beats per minute) after 2 liters of fluid resuscitation, positive abdominal examination findings, American Association for the Surgery of Trauma Organ Injury Scale Grade IV or V injuries by computed tomographic scan (unless younger than 15 years old), or associated severe head injuries (unless younger than 15 years old), or age greater than 55. The remainder of the patients were closely observed.

RESULTS

One hundred seventy-three patients were entered-six were excluded by death before operating room salvage, and one was excluded because of operation for a ruptured thoracic aorta. Therefore 166 patients were reviewed. Seventy splenectomies and 18 splenorrhaphies were performed, and 78 patients were treated nonoperatively (58% splenic salvage). Two failures occurred in the nonoperative group: a 16-year-old with a grade IV hilar injury was operated on on the eighth day after injury because of a continually falling hematocrit, and a 25-year-old with unresolved tachycardia was operated on at 6 hours (97% success rate). The patients in the operative group had a greater severity of injury as determined by mean Injury Severity Score of 32, 18 deaths, a mean transfusion requirement of 14 units of blood compared with mean injury severity score of 21, two deaths from brain injury, and no transfusions given in 58 of the 78 nonoperative cases.

CONCLUSIONS

Prospectively applied, these guidelines allow the safe nonoperative management of patients with blunt splenic injury.
