Laparoscopic splenectomy is a safe and effective option for patients with hematologic malignancy (HM), offering comparable outcomes to those with benign disease (BD). Larger spleens in HM patients may require longer operative times but do not preclude successful minimally invasive surgery.

Area of Science:

  • Surgical Oncology
  • Minimally Invasive Surgery
  • Hematology

Background:

  • Patients with hematologic malignancy (HM) often present with splenomegaly.
  • Splenectomy is a common procedure for managing conditions associated with enlarged spleens.

Purpose of the Study:

  • To compare the surgical outcomes of laparoscopic splenectomy in patients with hematologic malignancy (HM) versus those with benign disease (BD).

Main Methods:

  • A retrospective review of 64 consecutive laparoscopic splenectomies performed between March 1992 and August 1997.
  • Data collected prospectively included patient demographics, spleen size, operative details, and postoperative complications.

Main Results:

  • Patients with HM had significantly larger spleens and required longer operative times compared to patients with BD.

  • Conversion rates to open surgery were 21% for HM and 6% for BD.
  • Postoperative complication rates were similar (18% for HM vs. 11% for BD), with one death in the HM group.
  • Splenic size exceeding 27 cm necessitated conversion to open surgery.

    • Conclusions:

    • Laparoscopic splenectomy provides equivalent surgical outcomes for patients with HM and BD, despite larger spleens and longer operative times in the HM group.
    • The laparoscopic approach is recommended for HM patients, with splenic size >27 cm being a potential limitation.
    • Minimally invasive splenectomy is a viable option for managing splenomegaly in hematologic malignancies.
