  • Title: Subcapsular hematoma as a predictor of delayed splenic rupture.
    Author: Black JJ, Sinow RM, Wilson SE, Williams RA.
    Journal: Am Surg; 1992 Dec; 58(12):732-5. PubMed ID: 1456595.
    Abstract:
    Over the past 46 months at a level I trauma center, 966 computed tomography (CT) scans were performed for blunt abdominal trauma. Eighty-three (8.6%) demonstrated splenic injury, and 31 (3.2%) of these showed a subcapsular hematoma with or without associated parenchymal damage. Of the 31 patients, 23 were managed conservatively, based initially upon surgeons' preference (14 patients) and after March 1990 to conform to the authors' splenic trauma protocol (nine patients). The eight patients operated upon were hemodynamically stable and all underwent splenectomy. Subcapsular hematoma, as diagnosed by preoperative CT scan, was confirmed in each of the eight celiotomies. Parenchymal involvement, which had also been identified in these eight patients by CT, was evident at operation in all, and hilar involvement occurred in three. None of the 23 observed patients developed delayed splenic rupture. All were discharged home with outpatient follow-up in surgical clinic to at least 1 month without further complication. The authors came to the following conclusions: 1) Subcapsular hematoma is neither a predictor for delayed splenic rupture, nor by itself an indication for operative management of the injured spleen in the hemodynamically stable patient; 2) Degree of parenchymal injury based on CT morphology, specifically hilar involvement, signifies the need for laparotomy with splenectomy; 3) Splenorrhaphy has a reduced role in splenic trauma because most injuries now operated upon are severe.
