In 1952, Lortat-Jacob and Robert reported in the French literature on a method of controlled right hepatic lobectomy (7), and at about the same time Quattlebaum in this country described a similar technic (15). At the present time lobectomies are commonly performed for liver fracture, primary or secondary tumors, and cysts (2, 5, 11). Extensive hepatic resection is possible because of the liver's remarkable regenerative ability. The purpose of this paper is to report 3 cases from the Los Angeles County General Hospital, Los Angeles, Calif., in which hepatic resections and follow-up studies, including liver scans, were performed. Case Reports Case I: H. W., a 20-year-old Negro female, was admitted to the hospital on April 10, 1964, with blunt abdominal trauma following an automobile accident. The abdomen was distended, tender, and silent, and the patient was in shock. At laparotomy she was under anesthesia for seven hours and twenty minutes. Lacerations of the spleen and the right lobe of the liver were disclosed, and an 80 per cent right hepatic lobectomy and splenectomy were carried out. Two episodes of cardiac arrest on the table were managed by open heart massage. Twenty-two units of whole blood and 8 liters of miscellaneous fluids were required during surgery. The postoperative course was stormy, with pneumothorax, hypotension, low-grade fever, electrolyte imbalance, traumatic pancreatitis, wound infection, and bleeding tendency. The patient was treated with antibiotics, vitamin K, fibrinogen, blood, plasma, and intravenous fluids. Liver function tests were abnormal in the immediate postoperative period, but returned to normal or near normal in four to six weeks. Liver scans were obtained two and a half months, nine months, and eighteen months after hepatectomy (Figs. 1–3), using 150–170 microcuries of gold 198 and a 3-inch-crystal photoscanner. At the time of her last scan, the patient was clinically well, and the findings on her laboratory tests were normal. Case II: M. C, a 35-year-old Caucasian female, was admitted to the hospital Nov. 12, 1965, after suffering blunt abdominal trauma in an automobile accident. She was in mild shock, and the abdomen was silent and tender. At laparotomy a fracture of the hepatic right lobe was found, and 80 per cent of it was resected. The patient was under anesthesia for three hours and fifteen minutes. Postoperatively, she went into shock and required re-exploration and splenectomy for bleeding. Liver function tests returned to normal by three weeks, and recovery was fairly smooth. The liver scans in Figures 4 and 5 were obtained two months after hepatectomy. When the patient, was last seen in March 1966, liver function tests including Bromsulphalein retention were normal, and she felt well. Case III: Y. K., a 72-year-old Japanese male, underwent a 75 per cent gastrectomy for carcinoma in 1958.
