Evaluation of splenorrhaphy: a grading system for splenic trauma

Since April 1977, we have used splenorrhaphy as the procedure of choice for splenic trauma. To evaluate the efficacy of this procedure, we graded splenic injury based upon the extent of splenic repair in 77 patients with blunt abdominal trauma. This grading system is as follows: Grade 1-capsular treatment (five patients); Grade 2-capsular or parenchymal injuries requiring topical hemostatic agents (13 patients); Grade 3-parenchymal injuries requiring suture repair (nine patients); Grade 4-parenchymal injuries requiring partial splenic resection (seven patients); Grade 5-total splenic devascularization or uncontrollable bleeding from the splenic pedicle requiring splenectomy (43 patients). Twenty-nine patients had associated orthopedic injuries, and 42 patients had associated intra-abdominal or thoracic injuries. Mean operative time was 130 +/- 10 minutes. Operative time increased with severity of associated intra-abdominal injuries. Mean operative transfusion requirement was 500 +/- 100 cc of packed red blood cells. Transfusion requirements were not related to the severity of splenic injury. Twenty-three patients developed complications. Pancreatitis occurred in three patients, atelectasis of pneumonitis in eight patients, ten developed wound infections, and two patients required reoperation for small-bowel obstruction. Complication rates were not related to the degree of splenic injury. The grading system described herein provides a framework for sound clinical judgment and comparison of results in the management of splenic injuries.
