Partial splenectomy: the preferred alternative for the treatment of splenic cysts.

We report six pediatric patients who had a partial splenectomy for splenic cysts and a seventh patient who had a total splenectomy. There were six epidermoid cysts and one traumatic cyst. All patients had benign postoperative courses. All patients who underwent partial splenectomy had a significant postoperative rise in platelet count that subsequently returned toward baseline. This rise implies a loss of splenic function, although the exact meaning of this is unclear. All patients had late postoperative liver-spleen scans that showed mean spleen size and function to be normal. We have described several methods of partial splenectomy used at Children's Hospital of Philadelphia. Recommendations for patients undergoing partial splenectomy include preoperative pneumococcus and Hemophilus influenzae vaccinations and prophylactic antibiotics postoperatively. The antibiotics are terminated if a liver-spleen scan and platelet count at the end of 3 months' time are normal.
