Laparoscopic splenectomy.
OBJECTIVE
To study the safety and efficacy of laparoscopic splenectomy (LS) in patients with hematologic disorders requiring surgical intervention.


METHODS
A series of 103 consecutive adult patients underwent LS between 1992 and 1997 at our teaching hospital. Data were collected prospectively. The indications for splenectomy included idiopathic thrombocytopenic purpura (ITP), hereditary spherocytosis, autoimmune hemolytic anemia, and thrombotic thrombocytopenic purpura.


RESULTS
The mean spleen size was 14 cm (range 8.5-24 cm) and the mean weight was 263 g (range 40-210 g). Accessory spleens were detected in 12 patients with ITP and 17 patients in the study overall. In 12 patients, LS was combined with a laparoscopic cholecystectomy for gallstones. There were four conversions to open splenectomy, all for hemorrhage and all occurred in the first 50 patients. We have not converted a single patient in the last 2 years. The mean operative time was 161 minutes and was greater in the first 10 cases than the last 10. There were no deaths. Postoperative complications occurred in six patients, one necessitating a second procedure for a small-bowel obstruction. The average length of stay in the hospital was 2.5 days. After surgery, thrombocytopenia resolved in 84% of patients with ITP and anemia resolved in 92% of the patients with hereditary spherocytosis. After a mean follow-up of 38 months (range 2-565 months), four patients (6%) showed a relapse of ITP, three within 12 months of surgery.


CONCLUSIONS
Laparoscopic splenectomy can be performed safely and effectively in a teaching institution. LS in comparison with open surgery offers the same efficacy in the control of hematologic disease with the additional benefits of a minimally invasive approach. Laparoscopic splenectomy should therefore be considered the technique of choice and should prompt earlier consideration of surgery for patients with selected hematologic disorders.
