Summary:Liver dysfunction is a common problem in BMT recipients and it is important to determine the etiology in order to institute appropriate therapy. The purpose of this study was to evaluate the possible causes of liver dysfunction during the first post-transplant year in BMT recipients and to identify a possible relationship between pre-existing liver dysfunction and viral hepatitis with prognosis after BMT. We reviewed liver status before and after BMT in 130 consecutive patients at the Catholic Hematopoietic Stem Cell Transplantation Center. Liver dysfunction during the first post-transplant year occurred in 85 out of 101 (84.2%) allogeneic BMT recipients and 13 out of 29 (44.8%) autologous BMT recipients. In allogeneic BMT, GVHD and drug hepatotoxicity were major causes. In autologous BMT, drug hepatotoxicity was the most common cause. Eighteen out of 130 patients (13.8%) had abnormal liver function tests before BMT. These patients did not have an increased risk of post-transplant liver dysfunction, GVHD, and death compared to patients who had normal liver function tests prior to BMT. Nine patients were hepatitis B antigen positive and three patients were anti-HCV positive prior to BMT. There was no significant increase in the incidence of post-transplant liver dysfunction, GVHD, and death in these patients. Bone Marrow Transplantation (2000) 26, 193-197.

Although there was no statistically significant difference between patients treated with or without a transparent cap, hemoclipping with the aid of the cap made it possible to clip a lesion too tangential to be clipped without it. However, this study did not compare conventional hemoclipping with hemoclipping using a cap because the cap was only used in cases in which conventional clipping had failed.
