BACKGROUND: Laparoscopic splenectomy (LS) has rapidly become the preferred surgical treatment for idiopathic thrombocytopenic purpura (ITP), but its long-term efficacy for this disorder is unproved. This report documents the author's 5-year experience with, and long-term follow-up of, LS for ITP.
METHODS: Between September 1992 and September 1997, 30 patients with clinical ITP and intractable thrombocytopenia were referred as surgical candidates. Two of them (7%) were converted to open, and the other 28 underwent successful LS. The operative approach evolved from a supine lithotomy to right lateral decubitus position, and the harmonic scalpel became the primary dissection tool in the later part of the study.
RESULTS: The 28 successful LS patients constituted the study group. Accessory spleens were identified and resected in six patients (21%). Surgical times and blood loss averaged 2.4 h and 170 cc, respectively. The typical hospital stay was 2 days. Initial reversal of thrombocytopenia and ultimate cessation of oral steroids was achieved in 25 of 28 patients (89%). There were no deaths, but two patients had major complications (bleeding and pneumonia). All but two patients experienced a return to full activity and/or employment by 3 weeks post-LS. In the three cases that failed LS, none had residual splenic tissue on subsequent radionuclide scan. Long-term follow-up (2-60 months) was obtained in 22 of 28 patients (79%). The only death (at 13 months) resulted from oncologic disease. Twenty-one patients had lasting clinical remission of ITP. A positive preoperative response to oral steroids was the best predictor of success.
CONCLUSIONS: This 5-year experience with LS supports its use for the surgical treatment of ITP. The procedure is safe and efficacious, resulting in brief hospitalization, minimal recovery time, and excellent long-term results.
