BACKGROUND/AIMS: We encountered a case of posthepatectomy splenic enlargement and hypersplenism followed by disseminated intravascular coagulopathy with airway hemorrhage causing death.
METHODOLOGY: We, therefore, retrospectively investigated postoperative splenic enlargement, hypersplenism and disseminated intravascular coagulopathy by computed tomography and laboratory data in 57 hepatectomized patients with a malignant or benign disease in the postoperative period.
RESULTS: Of 32 patients with hepatocellular carcinoma or biliary tract carcinoma (group A), 12 with metastatic hepatic lesions (group B), and 13 with benign liver disease (group C); remarkable (20%) splenic enlargement was noted in 8 patients in group A, 2 in group B, and 2 in group C. Seven of the 12 patients were associated with liver cirrhosis, 5 with preoperative splenomegaly, and 8 had undergone major hepatectomy. Postoperative hypersplenism developed in 5 patients in group A, and one patient in group C. All of them were associated with liver cirrhosis or chronic hepatitis and preoperative splenomegaly, and five had undergone hepatic lobectomy or more extensive resections. All except for the disseminated intravascular coagulopathy case recovered. Statistically, splenic enlargement was significantly related to the extent of hepatectomy; lobectomy versus segmentectomy = 28.3 +/- 28.5% (n = 14) versus 12.4 +/- 13.8% (n = 20), (unpaired Student's t test, P = 0.037). Platelet counts of the patients with liver cirrhosis or chronic hepatitis is lower than those without the diseases, both pre- and postoperatively (14.0 +/- 6.0 x 10(4)/mm3 vs. 21.5 +/- 6.2 x 10(4)/mm3, P = 0.0001).
CONCLUSIONS: Postoperative hypersplenism was noted only in the patients with liver cirrhosis or chronic hepatitis and preoperative splenomegaly, and developed more frequently after larger hepatectomies than after smaller hepatectomies; 5 (45%) of 11 versus 1 (7%) of 14, chi 2 test, P = 0.026).
