Background: Despite extensive work‐up to establish the cause of splenomegaly, splenectomy may be required for diagnosis in certain situations. The aim of this study was to find out the role of diagnostic splenectomy in the current era.Methods: Between January 1989 and June 2004, 211 patients underwent splenectomy for indications other than trauma. In 41 (19%) patients, splenectomy was carried out for diagnostic purposes. Retrospective analysis of these patients was done for the purpose of the study.Results: All patients who underwent diagnostic splenectomy had a complete haemogram, biochemical tests for liver and renal function, bone marrow biopsy and abdominal ultrasonography before splenectomy. There were 28 (68%) men and 13 (32%) women with median age of 37 years (range, 6–62 years). The median duration of symptoms was 12 months (range, 1–180 months). Common presentations were fever (n = 27; 66%), malaise (n = 26; 63%), pallor (n = 33; 80%) and gross splenomegaly (n = 27; 66%). Thirty‐two (78%) patients had hypersplenism. Splenic lesions were shown in 14 (34%) patients on ultrasonogram and in 16 (39%) patients on contrast‐enhanced computed tomography scan of the abdomen. Open splenectomy was carried out in all patients. Seventeen (41%) patients had postoperative complications. Among these, three (7%) patients had postoperative bleeding. One patient died because of acute respiratory distress syndrome. Final histopathology of the spleen showed lymphoma in 15 (37%), tuberculosis in five (12%) and other lesions in five (12%) patients. Sixteen (39%) patients had only congestive splenomegaly.Conclusion: A high proportion of patients presenting with idiopathic splenomegaly will have underlying haematological malignancies even in tropical countries. The clinical presentation, laboratory profile and imaging findings were not helpful in differentiating between patients with haematological malignancies and non‐malignant conditions. Splenectomy still has an important role in establishing the pathology in patients presenting with idiopathic splenomegaly.
