title: Laparoscopic splenectomy in patients with hereditary spherocytosis: report on 12 consecutive cases.
abstract: Hereditary spherocytosis is an inherited hemolytic anemia caused by a deficiency in erythrocyte membrane proteins. Removal of the spleen may reduce the intra-splenic hemolytic process of the disease and, therefore, may correct the anemia. Furthermore, it seems to decrease the levels of serum bilirubin, thus reducing the formation of gallbladder stones. Indications and timing of splenectomy, however, are still debated. Twelve patients with severe hereditary spherocytosis operated on with laparoscopic splenectomy were retrospectively reviewed. Median age at diagnosis was 13.8 years (range 8-25 years). Male to female ratio was 5/7. Indications for laparoscopic removal of the spleen included anemia unresponsive to iron supplementation in eight patients (66.6 %) with increase need for red cells transfusions, and jaundice with symptoms related to cholelitiasis in four patients (33.3 %). Laparoscopic splenectomy was associated in four cases to laparoscopic cholecystectomy. Mean operative time was 50 min (range 40-75 min) with no conversion to open surgery. Mean hospital stay ranged from 3 to 7 days. In a 16-month follow-up, no complications were recorded and a persistent correction of anemia was observed. With the advent of laparoscopic surgery, splenectomy has been performed by this mini-invasive approach in referral centers. Laparoscopic splenectomy is an effective technique, when performed in patients with hereditary spherocytosis. Low complication rate and persistent correction of the hematologic disorders can be expected after the laparoscopic splenectomy, provided that a proper technique is performed and an experienced surgical team is available.
