The right margin of the caudate lobe is obscure. Therefore, a part of the caudate lobe (a part of the right side of the paracaval portion) seems almost always to remain with the right lobe graft during the standard harvesting procedure. We reviewed the intraoperative findings and the postoperative courses of donors and recipients of 11 consecutive living donor liver transplantations using right lobe grafts. Further, we used computed tomography during the postoperative course to investigate whether the remaining caudate lobe was present in the right lobe graft and whether it produced serious complications. Four recipients displayed an intraoperative bile leak from a remaining part of the caudate lobe after the completion of biliary reconstruction. With the exception of one case who developed repeated bile leakage from the same origin which eventually healed during a long-term postoperative course, Most recipients showed no postoperative biliary complications. Although a remaining caudate lobe was detected on postoperative computed tomography in all recipients, it produced no serious complications. In conclusion, a part of the right side of the paracaval portion of the caudate lobe almost always remains with a right lobe graft during the standard harvesting procedure. However, the implications of this phenomenon seem to be benign.
