This is a survey of 234 pediatric patients in whom staging laparotomy/splenectomy was carried out (1975 to 1981) in the course of the Intergroup Hodgkin's Disease in Childhood Study (IHDCS). Relapse has occurred in 44 of these patients, and 12 have died, 7 secondary to extension of lymphoma, 2 with herpes or pneumocystis infections, 2 with leukemia, and 1 from an unrelated accident. During the period of surveillance (mean 5.5 yr), five episodes of bacterial sepsis (positive blood cultures) have occurred, including two due to Streptococcus pneumoniae; and three, to Hemophilus influenzae. The former occurred in the small group of patients in this series who had not received the prescribed pneumococcal vaccination. No fatalities were associated with these septic episodes. Intestinal obstruction secondary to adhesions (benign) occurred in eight patients and was managed without intestinal resection or mortality. One patient required operative release of an obstructed ureter following laparotomy, and one, oophorectomy for an infarcted (transposed) ovary.
