Laparoscopic splenectomy and lymph node biopsy for hematologic disorders

Abstract

Objective: The authors audit the introduction of laparoscopic splenectomy and laparoscopic intra-abdominal lymph node biopsy and compare outcomes with a parallel cohort of patients undergoing open splenectomy.

Summary background data: Laparoscopic splenectomy was first reported in 1992. It was introduced into clinical practice at the Royal Brisbane Hospital in 1991. Between June 1991 and March 1994, 24 patients have undergone laparoscopic splenectomies and 23 patients have had laparoscopic intra-abdominal lymph node biopsies.

Methods: Laparoscopic splenectomy was performed using a four- or five-port technique. The splenic hilum was secured using a linear stapler cutter, and the spleen was removed after placing it in a laparoscopic bag. Lymph node biopsy was performed using a three- or four-port technique, depending on the site and size of the lymphadenopathy.

Results: Laparoscopic splenectomy was completed in 22 patients (92%). Median hospital stay was 3 days (range 2-7 days) and morbidity occurred in two patients (8%). Lymph node biopsy was completed laparoscopically in 21 of 23 patients (91%), with morbidity in two cases (9%). Median hospital stay was 2 days (range 1-6 days), with a diagnostic accuracy of 90%. Comparison with open splenectomy revealed that the laparoscopic approach took significantly longer to perform (p = 0.0002), but resulted in a significantly shorter hospital stay (p = 0.0005).

Conclusions: Both laparoscopic splenectomy and laparoscopic lymph node biopsy currently are used as the treatments of choice for hematologic disease in our institution.
