[Laparoscopic splenectomy as an alternative to open surgery in the treatment of autoimmune thrombocytopenia].
BACKGROUND
Several studies have shown the potential advantages laparoscopic splenectomy (LS) over open surgery. The aim of this study has been to evaluate the advantages of LS over open surgery in the treatment of autoimmune thrombocytopenia.


METHODS
54 consecutive patients splenectomized for the treatment of idiopathic thrombocytopenic purpura (ITP) or HIV-related thrombocytopenia were analyzed. Operative features (operative time, conversion to open surgery, accessory spleens), immediate (stay, analgesia and blood transfusion requirements) and late postoperative features (platelet count), as well as splenectomy-related complications in both surgical procedures were compared.


RESULTS
Between February 1990 and February 1997, 54 splenctomies were performed for the treatment of autoimmune thrombocytopenia (ITP, n = 47, and HIV-related thrombocytopenia, n = 7). Eighteen were performed through an open approach, and 36 by laparoscopy. Both groups were comparable with regard to age, sex, platelet count, disease duration and body mass index. LS was completed in 34 cases (conversion to open surgery: 5.5%). The incidence of accessory spleens was 11% in the LS group and 5.5% in the open surgery group. Postoperative morbidity (16% vs 28%) and blood requirements (25% vs 33%) were lower after LS, but the differences did not reach statistical significance. Analgesia requirements (7 [SD 3] vs 11 [6]; p < 0.01) and postoperative stay (3.8 [2.6] vs 7.4 [3] days; p < 0.01) were significantly shorter after LS. Following splenectomy, the platelet counts became normal in 72% of patients submitted to LS and 78% of patients in the open surgery group. After 20 and 63 months mean follow-up, one patient in each group developed late complications.


CONCLUSIONS
As compared to open surgery, LS offers a better immediate clinical outcome, with similar long-term results.
