The detectability of small daughter nodules of hepatocellular carcinoma by computed tomography after hepatic arterial infusion of Lipiodol (iodized oil) and by infusion hepatic angiography was studied in 102 cases. The Lipiodol was selectively accumulated by the tumor. Tumors and small daughter nodules appeared as high-density areas on computed tomography. In 24 cases daughter nodules were identified only by computed tomography. In 50 cases computed tomography demonstrated superior ability to detect the daughter nodules when compared with infusion hepatic angiography. In 21 cases the daughter nodules were detected for the first time in areas other than the main site of the primary tumor. Lipiodol-computed tomography is very effective in the diagnosis of daughter nodules of hepatocellular carcinoma.

リピオドール併用肝動脈塞栓術 (以下Lp-TAE) が非腫瘍部のエネルギー代謝に及ぼす影響を検討するために, Lp-TAEを施行した13症例を対象として, 肝硬変 (以下LC) の有無により2群に分け検討した. 一般肝機能は, LC (-), LC (+) 群ともにLp-TAE後4週以内に前値に回復した. ICGR15, ICGK値は, LC (-), LC (+) 群ともにLp-TAE後有意の変動を示さなかった. Lipid emulsion testからみたphagocytic indexは, LC (-), LC (+) 群ともにLp-TAE後高値を示すが, 2週目には前値に復しその後漸減して4週目でも低値を示す傾向にあった. 動脈血中ケトン体比は, LC (-) 群では, Lp-TAE後一過性の低下を示すが4週目には前値に復しているのに対し, LC (+) 群では4週目でも有意の低値を示し, 肝エネルギー代謝面での影響の残存が示唆された.

腫瘍径が5cm以下の肝癌11切除例の臨床的検討結果を報告するとともに, これら症例の腫瘍の浸潤の状態, 腫瘍の組織型, 非腫瘍部の病変を教室でこれまでに経験した腫瘍径5cm以上の肝癌と腫瘍径別に病理組織学的に対比検討した. 腫瘍径別の組織像は径3~5cm, 3cm以下では全例に被膜形成があるも門脈内腫瘍塞栓は腫瘍径と関係なく75~93%に認めた. 被膜への浸潤の程度も腫瘍径と関係なく50%以上の症例に認めた. 腫瘍部の組織型は3cm以下では高分化型のものが多く, 肝硬変の合併は5cm以上の60%に比べて, 5cm以下では88~100%と高率にみられた. 腫瘍径が3cm以下の肝癌でも早期癌といえる所見ではなく, さらに小型の肝癌を発見し検討する必要がある.
