Management and survival of meconium ileus. A 30-year review.

Cystic fibrosis patients born with meconium ileus (MI) have had an improved outcome over the last three decades. The authors reviewed the impact of surgical management and long-term nutritional care on the survival of patients with MI. Of the 59 cases of MI seen from 1959 to 1989, 48 cases were managed operatively using either the Bishop-Koop ileostomy (BK), the Mikulicz ileostomy, primary resection and anastomosis (RA), or ileostomy. Six-month survival of MI has improved from 37% to 100%. Nonoperative cases (n = 11) had 100% long-term survival. The RA survivors required less late operative intervention (20%) as compared with other surgical patients (81%). A comparison of serial growth percentiles of CF patients with MI with those of their non-MI CF peers showed similar long-term decreases. These data confirm: (1) There is an improved survival for MI independent of the surgical procedure; (2) The BK ileostomy is an effective and time-tested MI treatment; (3) Primary resection and anastomosis in selected cases may have a lower surgical morbidity rate; and (4) Meconium ileus does not adversely affect the long-term nutritional outcome of CF patients.

Pancreatic adenomas in infants and children: current surgical management.

Islet cell adenomas are an important consideration in infants and children with hypoglycemia due to hyperinsulinism. Between 1965 and 1977, 32 patients with hyperinsulinism were seen at the Children's Hospital of Philadelphia. Sixteen of these patients underwent surgery. Eight patients had single pancreatic adenomas, 5 of whom were infants under 1 yr of age. In 3 infants an adenoma was recognized and removed at the time of surgery. In 4 patients a subtotal pancreatectomy was successful in removing the adenoma. One infant is whom the adenoma was not included in the subtotal pancreatectomy died postoperatively with intractable hypoglycemia. Of the 7 patients cured by surgery, 6 are normal and 1 has brain damage due to delay in treatment of hypoglycemia. One child has mild diabetes. A combined medical and surgical protocol has been developed that permits rapid diagnosis of hyperinsulinism and selection of candidates for surgery. Infants under 1 yr of age who fail to respond to diazoxide should be explored. In children whose hyperinsulinism appears beyond 1 yr of age, surgery is indicated, since an adenoma is likely.

The surgical treatment of Wilms' tumor: results of the National Wilms' Tumor Study.

Surgical data derived from the 606 patients in the National Wilms' Tumor Study have been analyzed to determine the effect of surgical technique on results of treatment. In addition to surgical excision of the tumor, patients were treated with chemotherapy and radiation therapy according to the study protocol. Under these controlled conditions, certain aspects of surgical technique which have traditionally been thought to be important for success appear to be irrelevant. Physical characteristics of the tumor, preoperative rupture and vascular invasion by tumor were not associated with higher relapse rates. Large tumors, those with capsular infiltrations, and tumors with spread to lymph nodes higher recurrence rate. Operative spill increased the chance of abdominal recurrence. There was no evidence that early ligation of the renal vein was of value in prevention of recurrence, nor was incomplete removal of tumor associated with an increase in relapse rate. Although several critical factors of surgical technique were not studied, it is clear that others are not significant and need not be continued.

Juvenile fibromatosis with invasion of the mandible: report of two cases.

Two cases of juvenile fibromatosis involving the mandible were found in children aged 1 1/2 and 2 1/2 years. The tumors, while histologically benign, were clinically aggressive, causing bone erosion and destruction and invading adjacent normal soft tissue structures with firm fibrous tumor extensions. In each instance, the lesion was completely removed by radical local surgery with no recurrence after a seven-year follow-up. The pertinent literature, consisting of six previously reported cases, has been reviewed.

Nonoperative treatment of duodenal hematomata in childhood.

Blunt abdominal trauma, often apparently trivial in nature, may produce intramural hematoma causing complete duodenal obstruction. A child with abdominal pain, persistent vomiting and upper abdominal tenderness should be carefully questioned for a history of trauma. Prompt upper gastrointestinal x-rays will allow early and definitive diagnosis. Previously recommended treatment varies from immediate surgical intervention to observation followed by exploratory laparotomy at a later date. We have treated nine patients with duodenal obstruction caused by intramural hematoma of which eight were successfully managed with nasogastric suction and parenteral fluid administration. One patient had the hematoma evacuated at surgery. This report reviews our experience.

Survival in bilateral Wilms' tumor--review of 30 National Wilms' Tumor Study cases.

Bilateral tumors were found in 33 patients or 5.4% of 606 children enrolled in the National Wilms' Tumor Study. Twenty six of 30 patients (87%) for whom detailed clinical information is available survived 2 yr after conservative surgery and radiation therapy. All patients were given one or more chemotherapeutic agents. A variety of surgical procedures were used including biopsy only, nephrectomy, and partial nephrectomies. Radiation therapy doses ranged widely, but between 1000 and 2000 rad apparently sufficed for local control in most cases. Recommendations regarding management by surgery, radiation therapy, and chemotherapy are given.

Report of a case of gross thymic hyperplasia in a child.

A large thoracic mass and a mediastinal lymph node were excised from an infant with a peripheral blood and bone marrow lymphocytosis. The 224-mass was composed of histologically normal thymus, and the lymph node architecture was partially effaced. Hypogammaglobulinemia was detected two years after thymectomy. The enormous thumus in this case fits the classic gross pathologic definition of hyperplasia. The possibility of associated thymic hyperfunction in this case is discussed.
