Laparoscopic splenectomy for benign and malignant hematologic diseases: 35 consecutive cases

The feasibility and safety of laparoscopic splenectomy (LS) has been shown for a variety of diseases with small or moderately enlarged spleens. Immune thrombocytopenic purpura thus has become the typical indication for LS, although few data are available to demonstrate any superiority of the laparoscopic approach over conventional surgery for this indication. We retrospectively analyzed 35 cases of LS for benign (22 patients) or malignant (13 patients) hematologic disorders. LS was attempted irrespective of the volume of the spleen. The overall operative mortality rate was 2.9%, and complications occurred in 23% of all patients, The conversion rate was 9%, and accessory spleens were found in 17% of patients. Although the patients with malignant disease were significantly older, were higher operative risks (ASA score), had much larger spleens, and required longer operative times, more conversions to laparotomy, and more blood transfusions than patients with benign disease, their mortality and complication rates and the duration of their hospital stays were not significantly different front those with benign disease, They also compare Favorably with the results of conventional surgery for the same indications. Patient selection, operative technique, and outcome of laparoscopic and conventional splenectomy are discussed with regard to the literature, Although the experience with LS for these indications is still limited, the reported results indicate that LS may be as beneficial for patients with malignant as for those with benign hematologic conditions.
