Laparoscopic Splenectomy for Splenic Tumors

ABSTRACT

PURPOSE: Laparoscopic splenectomy (LS) is the procedure of choice in treating hematologic diseases, however there are controversies concerning malignancy and splenomegaly. This study was performed in order to examine the safety and efficacy of LS and hand-assisted laparoscopic splenectomy (HALS) in the management of patients with various splenic tumors and splenomegaly. METHODS: Fifteen patients who had undergone laparoscopic splenectomy for suspected splenic tumors between May, 1998 and December, 2000 were evaluated. We conducted a review, recording previous abdominal surgery, diagnostic work up, size of spleen, accessory spleen, type of surgery, morbidity, mortality, and length of hospital stay. A retrograde analysis was conducted using the medical records of the patients. RESULTS: The average splenic length was 22.4 cm (range, 14~37 cm), and the average weight was 1,210 gm (range, 210~3,700 gm). There were two types of operations performed. LS was accomplished in 7 cases and HALS in 8 cases. All operations were completed without any conversion to open surgery. The average intraoperative blood loss was 153.5 ml (range, 45~830 ml). The average postoperative stay was 5.2 days (range, 3~9 days). Only one complication (subphrenic abscess) developed (7%), which was resolved by percutaneous drainage. No deaths occurred. The pathologic findings were lymphoma (4), hemangioma (4), islet cell tumor (2), lymphangioma (3), myelofibrosis (1), and hematoma (1). CONCLUSION: LS and HALS are safe and feasible procedures for the treatment of most neoplastic splenic diseases with splenomegaly. HALS is an alternative approach for overcoming the technical and oncological challenges that often accompany malignant splenic diseases such as splenomegaly, perisplenitis and hilar lymphadenopathy. As the indications for LS including HALS are expanded, the role of LS and HALS in various splenic tumors will become more clearly defined.
