Surgical implications of hepatic venocclusive disease following bone marrow transplantation.

Overview

Hepatic venocclusive disease occurs with a spectrum of severity in an estimated 21% of bone marrow transplant patients. Clinical features include severe right upper quadrant pain, ascites, weight gain and initially minimal derangement of liver function. In contrast to hepatic graft versus host disease, venocclusive disease usually occurs within the first three weeks of engraftment and in autologous grafts. Urgent surgical consultation is requested when these features are prominent enough to mimic common acute processes requiring laparotomy. This condition must be included in the differential diagnosis in order to avoid an unnecessary laparotomy in this select group of patients who are usually severely thrombocytopenic and leukopenic. Clinical diagnosis alone is very reliable.
