Splenectomy in hematologic disorders. The ever-changing indications.

Area of Science:

• Surgical Oncology
• Hematology
• Clinical Outcomes Research

Background:

• Splenectomy practices for hematologic disorders have evolved over time.
• Changes in surgical indications and diagnostic techniques influence procedure frequency.
• Understanding historical trends in splenectomy is crucial for current clinical practice.

Purpose of the Study:

• To compare splenectomy procedures performed for hematologic disorders across two distinct time periods (1946-1962 and 1963-1982).
• To identify factors contributing to observed changes in splenectomy incidence and indications.
• To evaluate the impact of these changes on patient mortality rates.

Main Methods:

• Retrospective analysis of splenectomy cases performed at the University of Virginia Medical Center.
• Comparison of data from two series: 1946-1962 (Series I) and 1963-1982 (Series II).
• Analysis of procedure indications, patient outcomes, and associated mortality.

Main Results:

• Splenectomy rates increased substantially in Series II (20/year) compared to Series I (5.5/year).
• The evolution of staging laparotomy for lymphomas, particularly Hodgkin's disease, was a major driver of increased splenectomy rates.
• Mortality rates decreased from 6.3% in Series I to 4.0% in Series II, with no deaths recorded after 1979.

Conclusions:

• The incidence of splenectomy for hematologic disorders has significantly changed over the decades.
• Shifting diagnostic and therapeutic strategies, especially for lymphomas, have altered splenectomy indications.
• Improved surgical techniques and patient management have led to reduced mortality associated with splenectomy.
