title: Is splenectomy after trauma an endangered species?
abstract: Nonoperative management of splenic trauma is now the most common treatment modality for splenic injuries and splenectomy has almost disappeared in some trauma centers. Splenectomy for cancer staging is infrequently performed suggesting that the indications for splenectomy continue to evolve. We evaluated a state database to assess a communitywide experience with splenic surgery. International Classification of Diseases, 9th Revision, Clinical Modification diagnosis codes were used to determine the indication for splenic surgery. Indications for splenic surgery were listed as trauma (injury codes), medical (hematological diseases, neoplasms, or procedures in which the spleen might be removed contiguously like distal pancreatectomy), or incidental (noncontiguous procedures). Splenectomies for medical indications (n = 607, 43%) were more common than splenectomies for trauma (n = 518, 37%) or incidental splenectomies (n = 276, 20%). Splenectomy for medical reasons was associated with hematologic disease in 56 per cent, neoplastic disease in 34 per cent, and other diagnoses in 10 per cent of cases. Incidental splenectomies were most commonly associated with operations on the esophagus/stomach (32%) and colon (30%). Mortality rate and length of stay were greatest for incidental (14.4 +/- 0.9 days, 10.9% mortality) compared with trauma (11.0 +/- 0.5 days, 7.7% mortality) or medical (9.7 +/- 0.4 days, 4.8% mortality) splenectomies (all P < 0.05 versus incidental). Our results suggest that in the era of nonoperative management of splenic injuries, medical indications now represent the most common reason for splenectomy. As laparoscopic techniques for elective splenectomy become more common, the changing indication for splenectomy has important ramifications for surgical education and training.
