[Explorative laparotomy with splenectomy in malignant lymphomas (author's transl)]

Area of Science:

• Oncology
• Surgical Pathology
• Diagnostic Procedures

Context:

• Malignant lymphomas, including Hodgkin lymphoma, require accurate staging for effective treatment planning.
• Preoperative clinical staging may not always reflect the true extent of intra-abdominal disease.
• Exploratory laparotomy offers a direct method for assessing abdominal involvement in lymphomas.

Purpose:

• To evaluate the impact of exploratory laparotomy on the clinical staging of malignant lymphomas.
• To assess the diagnostic yield and safety of exploratory laparotomy in lymphoma staging.
• To determine if exploratory laparotomy improves the definition of lymphoma extension, particularly in the abdomen.

Summary:

• A study involving 31 patients with malignant lymphoma (Hodgkin or non-Hodgkin) between 1971 and 1974 utilized exploratory laparotomy for staging.
• The procedure involved a median incision for multiple lymph node, liver, and spleen biopsies.
• Exploratory laparotomy changed the preoperative clinical stage in 17 out of 31 patients (54%), with shifts from lower to higher stages in untreated cases and vice versa in treated cases.
• Postoperative mortality was nil, and morbidity was 16% (5 out of 31 patients).

Impact:

• Exploratory laparotomy provides a more precise definition of lymphoma extent, especially intra-abdominal disease, leading to optimized treatment strategies.
• The study supports the recommendation of exploratory laparotomy with splenectomy for staging most malignant lymphomas, excluding Stage IV disease with proven biopsy.
• This surgical staging approach enhances therapeutic decision-making and patient management in malignant lymphoma cases.
