Postoperative course is reported in 52 children with malignant tumors (
neuroblastoma
, Wilms-tumor, non-Hodgkin-lymphoma, osteosarcoma etc.) who were operated on between 1979 and 1987. 26 children received chemotherapy prior to surgery, whereas 26 children were operated on without preceding chemotherapy (control group). Most children were under six years of age. 15 Children (57.7%) with preoperative chemotherapy developed early postoperative complications, such as sepsis, pneumonia, suture dehiscence, woundhealing disturbances and ileus, whereas this was the case in only 5 children (19.2%) without preoperative chemotherapy (P 0.0005). Four of the children with preoperative chemotherapy (15.4%) sustained late complications, such as local recurrence or mechanical
bowel obstruction
, whereas none of the control children did so. Lethality rate from underlying disease did not differ in both groups during follow-up (5 = 19.2% vs. 5 = 19.2%). This demonstrates that the surgeon must carefully be aware of an increased possibility of early and late complications in children who have to undergo surgery for malignant tumors following preoperative chemotherapy.

Intestinal obstruction
is a common postoperative complication and is usually related to peritoneal adhesion formation. A less well-recognized cause is postoperative intussusception (POI). Thirty-six instances of POI in children (aged 1 month to 18 years) were treated between 1970 and 1987. POI followed Nissen fundoplication in 9 patients,
neuroblastoma
resection in 5, small-bowel procedures in 4, inguinal herniorrhaphy in 3, pull-through procedures in 3, ureterostomy in 2, thoracic procedures in 2, ventral hernia in 1, nephrectomy in 1, hepatic resection in 1, Heller myotomy in 1, ventriculo-atrial shunt in 1, and gastrocystoplasty in 1. Initial symptoms included bilious vomiting or increased nasogastric drainage (after initial return of gut function) in 26 patients, abdominal distension in 24, irritability in 10, intermittent pain in 7, palpable abdominal mass in 2, rectal bleeding in 2, and lethargy in 1. The symptoms occurred 1 to 24 days (mean, 8 days) after the initial surgery. Plain abdominal radiographs revealed multiple air-fluid levels in 31 and an "adynamic ileus" in five patients. Barium contrast techniques could successfully reduce two ileocolic and one distal ileo-ileal lesions. The remainder necessitated operative management. Manual reduction was possible in 29 cases, and four children with diagnostic delay required bowel resection and an anastomosis for intestinal necrosis. The site of intussusception was ileo-ileal in 23 patients, jejunojejunal in 6, ileocolic in 5, and jejuno-ileal in 2. The diagnosis of POI should be considered in children with signs of bowel dysfunction in the early postoperative period. Contrast studies are of limited value, since most cases are confined to the small bowel. A high index of suspicion and prompt laparotomy will usually allow manual reduction of the lesion. Diagnostic delay may result in bowel necrosis.

A primary neoplasm of the right adrenal gland in a 4-year-old boy was discovered after the patient developed
bowel obstruction
following an appendectomy. Until the histologic examination, the tumor was thought to be a
neuroblastoma
. However, the intra-adrenal tumor was composed of blastematous nodules, primitive tubules, and glomeruloid structures whose overall composition resembled a Wilms' tumor. Other than a single focus of mucinous glands, the tumor lacked the range of somatic tissue types of a teratoma. Approximately 50 cases of putative extrarenal Wilms' tumor have been reported. The retroperitoneum is one of the more common primary sites, yet our case is the first documented example of a neoplasm with features of a Wilms' tumor arising in the adrenal. Based on the embryologic and anatomic relationship between the adrenal gland and kidney, it is somewhat surprising that other instances of similar appearing tumors have not been described before the present case. Our patient was managed on a Wilms' tumor protocol and remains tumor free 15 months after surgery.
