Abstract
BACKGROUND: The most prevalent method of treating splenic injury is by splenectomy. This method is followed by postoperative complications. Therefore, less invasive procedures such as splenic angioembolization are introduced. This technique needs appropriate training, a high-tech setting and could be followed by complications. Thus, not all surgeons agree to do this procedure. Splenic hilar ligation of main vessels is a non-invasive procedure which has similarities to a splenectomy with unknown results.
OBJECTIVES: We aim to evaluate and compare splenectomy and hilar ligation.
METHODS: Thirty rats were divided into splenectomy and splenic hilar ligation groups. An identical grade 3-spleen injury was performed on all rats. After 6 weeks blood samples were obtained and hematologic and immunologic aspects were measured in their serum. Giemsa stained peripheral blood smears were obtained from the ligation group.
RESULTS: Comparing the above-mentioned variables before and after the surgery in each groups showed statistical significance in all aspects except IgM, C4 and platelets levels in ligation group (P value: 0.213, 0.059 and 0.649 respectively). Analysis revealed significant deference in postoperative WBC, IgM and C4 levels between splenectomy and ligation group (P value: < 0.001, < 0.001 and 0.026 respectively).
CONCLUSION: Splenic hilar ligation of main vessels is an easy way of treating splenic injury in hemodynamically stable patients with less postoperative complications. Therefore, it can be performed by all surgeons in all kind of medical centers. Spleen remains viable and continues its role although some aspects of its function become interrupted.
