Endolymphatic radiotherapy in malignant lymphomas. A clinical evaluation of 285 patients.

The authors report treatment of inguinal and retroperitoneal lymph nodes of 285 malignant lymphomas (143 Hodgkin's disease and 142 lymphoreticular sarcomas) with Lipiodol Fluide 131I (endolymphatic radiotherapy). From 1961 to 1966 the radioactive contrast material was injected in doses ranging from 0.2 to 2.5 mc/cc (10 cc each foot). Adequately opacified nodes responded promptly with marked and progressive reduction in size. When indicated, a second administration of Lipiodol 131I in a dose of 2.5 mc/cc was always feasible. Several factors prevented a homogeneous and satisfactory distribution of radioactive contrast material throughout the iliac and the para-aortic nodes in one third of the cases. Therefore, in many instances patients had to be treated with external radiation therapy. Histopathologic examination of lymph nodes removed at exploratory laparotomy (four cases) or at autopsy (ten cases) confirmed that Lipiodol 131I did not fill all the iliac and para-aortic nodes and that destruction of lymphomatous tissue was often incomplete. Recurrences were seen mostly in abnormal adequately filled nodes opacified with high doses of Lipiodol 131I. In Hodgkin's disease they occurred particularly in the para-aortic area and in lymphoreticular sarcomas in the inguinal and iliac chains. Side effects were minimal. They included amenorrhea, pulmonary insufficiency, hepatic failure and hemolytic anemia. Clinical and histologic signs of pulmonary and hepatic fibrosis were not seen. The authors conclude that endolymphatic radiotherapy should not be considered as a radical treatment for retroperitoneal adenopathies in malignant lymphomas and that its role as a prophylactic therapeutic tool deserves more extensive long-term studies.

Early hemodynamic changes following selective distal splenorenal shunt for portal hypertension: comparison of surgical techniques.

Ninety patients with cirrhosis undergoing elective distal splenorenal shunt (DSRS) for variceal bleeding between January, 1977 and September, 1988 comprised the study group. In 63 cases, the original technique of Warren was used and, in 15, the modified Britton procedure was employed. Twelve patients had a DSRS plus splenopancreatic disconnection. Thirty-four had alcoholic cirrhosis and 56 had nonalcoholic cirrhosis. Intraoperative portal pressure remained high after the shunt (29.4 cm H2O) even if its initial value was probably decreased by the loss of the splenic flow. Splenic pressure was reduced to 21 cm H2O. The hepatic artery diameter enlarged even after selective shunt (from 6.5 to 7.1 mm). The persistence of a high portal pressure allowed for the preservation of hepatopedal portal flow in 87% of cases. Disconnection between the high-pressure mesenteric area and the low-pressure splenic area seemed to be ideal in only 17% of cases. Fifty-five percent of cases had the early development of minimal or moderate portomesenteric gastrosplenic (PM-GS) collateral pathways. In 33%, the PM-GS collaterals were generally abundant and often allowed visualization of the splenic and caval veins during the venous phase of the superior mesenteric arteriograms. In this group, portal flow was generally highly reduced and even abolished. The incidence of portal thrombosis was 11%. Early angiographic checks after DSRS did not show a different hemodynamic behavior between alcoholics and nonalcoholics. Splenopancreatic disconnection seems to prevent the development of collaterals and the loss of portal perfusion after shunt surgery.
