Experience with laparoscopic splenectomy

The laparoscopic splenectomy (LS) often is adopted to treat children affected by hematologic diseases. Many of the pitfalls of LS are related to the 2 steps-dissection and extraction. Although various methods have been adopted, the conversion rate still is too high during the learning curve period. The authors analyse their experience in 54 laparoscopic splenectomies performed by their teams in 3 European countries.

From 1995 to 1999, 54 children underwent laparoscopic splenectomy, 4 of whom also underwent a concomitant cholecystectomy. There were 29 girls and 25 boys with ages ranging between 4 and 19 years (median, 8.1 years). All patients underwent an elective laparoscopic splenectomy: Thirty children had hereditary spherocytosis, 13 had an idiopathic thrombocytopenic purpura, 10 were affected by a beta thalassemia, and 1 child had sickle cell disease.

Mean operating time was 140 minutes (range, 100 to 250 minutes). Hospital stay ranged from 2 to 6 days (median, 3 days). In 7 patients the spleen was removed through a 7-cm minilaparotomy; in another 46 cases the spleen was captured into an extraction bag, fragmented, and then removed through the umbilical or left orifice. There was one conversion to open surgery because of a camera failure during the operation.

On the basis of our experience we believe that the operating time of LS is still too long compared with open surgery, and the extraction phase still not simple enough. A perfect control of hemostasis is fundamental because severe complications can arise from even a slight bleeding episode. It also is very important to search for and remove any accessory spleens. In our series this occurred in 7 patients, one of whom had 3 accessory spleens. The laparoscopic approach is today a good alternative to open splenectomy.
