A laparoscopic approach to partial splenectomy for children with hereditary spherocytosis

Background: Partial splenectomy is sometimes used for children with hereditary spherocytosis (HS) to reduce hemolysis while retaining some splenic immune function. Previous reports have described a partial splenic resection through a laparotomy incision. Whereas laparoscopic total splenectomy for HS is well-established, laparoscopic partial splenectomy (LPS) has not been described. The authors have developed a novel LPS technique that combines the benefits of partial splenectomy with those of a laparoscopic approach. Methods: A chart review was conducted for three children with HS who underwent LPS, with approximately one-fourth of the spleen left on the basis of the short gastric arterial supply. Results: The mean preoperative spleen size was 17.6 cm. The mean preoperative hemoglobin count was 100 g/l, and the postoperative hemoglobin count was 133 g/l. All three patients reported reduced malaise and increased energy levels. There was no recurrent anemia at the 1- to 2-year follow-up evaluation. Conclusion: The LPS procedure is a safe and effective approach to HS that resolves anemia, potentially retains some splenic immunity, and confers the benefits of a minimal access technique.
