OBJECTIVE To describe the outcome of young adults treated for hypoxemic respiratory failure with extracorporeal membrane oxygenation as neonates. DESIGN The study was designed as a multisite, cross sectional survey. SETTING The survey was completed electronically or on paper by subjects and stored in a secure data base. SUBJECTS Subjects were surviving neonatal extracorporeal membrane oxygenation patients from eight institutions who were18 years old or older. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS A questionnaire modified from the 2011 Behavioral Risk Factor Surveillance System and the 2011 National Health Interview Survey with additional unique questions was completed by subjects. Results were compared to age-matched national Behavioral Risk Factor Surveillance System and National Health Interview Survey data. One hundred and forty-six subjects participated (8.9% of eligible candidates). The age at questionnaire submission was 23.7 ± 2.89 years. Subjects differed statistically from national cohorts by being more satisfied with life (93% vs 84.2%); more educated (some college or degree; 80.1% vs 57.7%); more insured for healthcare (89.7% vs 72.3%); less frequent users of healthcare in the last 12 months (47.3% vs 58.2%); more limited because of physical, mental, and developmental problems (19.9% vs 10.9%); and having more medical complications. Furthermore, learning problems occurred in 29.5% of the study cohort. The congenital diaphragmatic hernia group was generally less healthy and less well educated, but equally satisfied with life. Perinatal variables contributed little to outcome prediction. CONCLUSIONS Most young adult survivors in this study cohort treated with extracorporeal membrane oxygenation as neonates are satisfied with their lives, working and/or in college, in good health and having families. These successes are occurring despite obstacles involving health issues such as asthma, attention deficit disorder, learning difficulties, and vision and hearing problems; this is especially evident in the congenital diaphragmatic hernia cohort. Selection bias inherent in such a long-term study may limit generalizability, and it is imperative to note that our sample may not be representative of the whole.

The aim of this analysis was to report a multidisciplinary series comparing choledochoceles to Todani Types I, II, IV, and V choledochal cysts.Choledochoceles have been classified as Todani Type III choledochal cysts. However, most surgical series of choledochal cysts have reported few choledochoceles because they are managed primarily by endoscopists.Surgical, endoscopic, and radiologic records were reviewed at the Riley Children's Hospital and the Indiana University Hospitals to identify patients with choledochal cysts. Patient demographics, presenting symptoms, radiologic studies, associated abnormalities, surgical and endoscopic procedures as well as outcomes were reviewed.A total of 146 patients with "choledochal cysts" including 45 children (31%) and 28 with choledochoceles (18%) were identified, which represents the largest Western series. Patients with choledochoceles were older (50.7 vs. 29.0 years, P0.05) and more likely to be male (43% vs. 19%, P0.05), to present with pancreatitis (48% vs. 24%, P0.05) rather than jaundice (11% vs. 30%, P0.05) or cholangitis (0% vs. 21%, P0.05), to have pancreas divisum (38% vs. 10%, P0.01), and to be managed with endoscopic therapy (79% vs. 17%, P0.01). Two patients with choledochoceles (7%) had pancreatic neoplasms.Patients with choledochoceles differ from patients with choledochal cysts with respect to age, gender, presentation, pancreatic ductal anatomy, and their management. The association between choledochoceles and pancreas divisum is a new observation. Therefore, we conclude that classifications of choledochal cysts should not include choledochoceles.

Objectives: The purpose of this report is to evaluate the efficacy of and complications observed after laparoscopic splenic procedures in children. Methods: Review of a prospective database at a single institution (1995-2006) identified 231 children (129 boys; 102 girls; average age 7.69 years) undergoing laparoscopic splenic procedures. Results: Two hundred twenty-three children underwent laparoscopic splenectomy (211 total; 12 partial) by the lateral approach. Indication for splenectomy was hereditary spherocytosis (111), immune thrombocytopenic purpura (36), sickle cell disease (SCD) (51), and other (25). Four (2%) required conversion to an open procedure. Eight additional laparoscopic splenic procedures were performed: splenic cystectomy for epithelial (4) or traumatic (2) cyst, and splenopexy for wandering spleen (2). Average length of stay was 1.5 days. Complications (11% overall, 22% in SCD patients) included ileus (5), bleeding (4), acute chest syndrome (5), pneumonia (2), portal vein thrombosis (1), priapism (1), hemolytic uremic syndrome (1), diaphragm perforation (2), colonic injury (1), missed accessory spleen (1), trocar site hernia (1), subsequent total splenectomy after an initial partial (1), and recurrent cyst (1). Subsequent operations were open in 3 (colon repair, hernia, and missed accessory spleen) and laparoscopic in 2 (completion splenectomy, and cyst excision). There were no deaths, wound infections, or instances of pancreatitis. Conclusions: Laparoscopic splenic procedures are safe and effective in children and are associated with low morbidity, higher complication rate in SCD, low conversion rate, zero mortality, and short length of stay. Laparoscopic splenectomy has become the procedure of choice for most children requiring a splenic procedure.

OBJECTIVE: The authors evaluated the risk of necrotizing enterocolitis (NEC) in very low birth weight infants receiving indomethacin (INDO) to close patent ductus arteriosus (PDA). BACKGROUND DATA: Controversy exists regarding the best method of managing very low birth weight infants with PDA and whether to employ medical management using INDO or surgical ligation of the ductus. METHODS: Two hundred fifty-two premature infants with symptomatic PDA were given intravenously INDO 0.2 mg/kg every 12 hours x 3 in an attempt to close the ductus. Patients were evaluated for sex, birth weight, gestational age, ductus closure, occurrence of NEC, bowel perforation, and mortality. RESULTS: There were 135 boys and 117 girls. The PDA closed or became asymptomatic in 224 cases (89%), whereas 28 (11%) required surgical ligation. Ninety infants (35%) developed evidence of NEC after INDO therapy. Fifty-six were managed medically; surgical intervention was required in 34 of 90 cases (37.8%) or 13% of the entire PDA/INDO study group. Bowel perforation was noted in 27 cases (30%). Factors associated with the onset of NEC included gestational age < 28 weeks, birth weight < 1 kg, and prolonged ventilator support. The overall mortality rate was 25.5%, but was higher in infants with NEC versus those without. The highest mortality was noted in perforated NEC cases. The PDA/INDO patients were compared with a control group of 764 infants with similar sex distribution, birth weights, and gestational ages without PDA who did not receive INDO. Necrotizing enterocolitis occurred in 105 of 764 control patients (13.7%), including 13 (12.3%) with perforation. The overall mortality rate of controls was 25%, which was similar to the overall 25.5% mortality rate in the PDA/INDO study group. CONCLUSION: These data indicate that there is increased risk of NEC and bowel perforation in premature infants with PDA receiving INDO. Mortality was higher in the PDA/INDO group with NEC than those PDA/INDO infants without NEC.

Lymphoma arising in the liver is uncommon in adults and rare in children. A 12-year-old boy with hepatomegaly and jaundice had a calcified intrahepatic large-cell lymphoma of B-cell origin that expressed bcl-2 protein and had near-tetraploid chromosome number with a t(8;14) (q24;q32) and a homogeneously staining region (HSR). This tumor, only the fourth example of primary hepatic lymphoma in a child, has the rare finding of an HSR before treatment and is the first human lymphoma with t(8;14) that expresses bcl-2 protein. In addition, the demonstration of extensive calcification in the tumor by computed tomography scan is highly unusual for lymphoma. Lymphoma must be considered in the differential diagnosis of primary liver tumors in children and adults, especially if the serum alpha-fetoprotein level is normal.

Three hundred two infants with necrotizing enterocolitis (NEC) were treated from 1972 to 1990. One hundred eighteen were treated medically while 184 infants required operation. Comparisons were made between two treatment periods, 1972 to 1982 (n = 176) and 1983 to 1990 (n = 126). Infants in the more recent era were of lower birth weight (1505 +/- 853 g versus 1645 +/- 836 g), earlier gestational age (30.4 +/- 4.7 weeks versus 32.4.5 weeks; [p less than 0.01]), had symptom onset at an older age (15.7 +/- 13.9 days versus 10.0 +/- 10.8 days; [p less than 0.001]), and a lower incidence of hyaline membrane disease (p less than 0.001). Fewer patients in the 1983 to 1990 group had acidosis (p less than 0.001) and severe oliguria (p less than 0.001). Operation was performed sooner after diagnosis in the second group (2.6 versus 3.8 days; [p less than 0.001]). Survival was unaffected by sex, maternal complications, or whether infants were inborn or transferred from other facilities. Improved survival (1983 to 1990) was observed in those infants between 24 to 27 weeks gestation (p less than 0.002) and those weighing less than 1000 g (p less than 0.001). Since 1983 portal vein air (PVA) on abdominal radiographs was used as an indicator for operation. Survival in infants with PVA has improved from 29% to 64% (p less than 0.02). Despite patients being more immature and weighing less, the overall survival rate improved from 58% (1972 to 1982) to 82% (1983 to 1990) (p less than 0.001). Operative survival rate improved from 51% to 75% (p less than 0.002). Long-term survival was 75% overall and 65% for surgical infants in the 1983 to 1990 group (p less than 0.05).

The increased use of child safety seats and seat belt restraints has significantly reduced the incidence of severe head injuries associated with motor vehicular accidents. However, an increase in the number of both acutely recognized intestinal perforations and delayed obstructions due to ischemic strictures has been noted. This report describes two children with delayed onset of intestinal obstruction related to the "seat belt syndrome" who presented with bilious emesis 3 to 6 weeks following an unrecognized lap belt injury. At laparotomy, a volvulus around an omental band adherent to a resolving traumatic mesenteric hematoma was the basis of the obstruction in both cases. The volvulus resulted in a stricture in each instance that required resection and end-to-end anastomosis. The diagnosis of posttraumatic intestinal obstruction should be suspected in children who develop nausea and bilious emesis following motor vehicular accidents in which they were wearing lap belts.

Forty-two infants and children with retroperitoneal solid tumors underwent second operative procedures. Twenty-three children had stage III (4) or stage IV (19) neuroblastoma and 19 had Wilms' tumor. This report suggests that second-look procedures are quite beneficial in selected cases. In children with Wilms' tumor, second procedures are most useful in those patients inadequately staged with flank operations, in cases of bilateral tumors, and in children with initially unresectable tumors following cytoreduction. Patients with significant tumor spill at a previous procedure may also benefit from early reoperation. Late recurrence of tumor, especially in children with unfavorable histology and/or hematogenous liver metastases, carries an ominous prognosis. Ten of the 19 patients with Wilms' tumor are long-term survivors (52.6%). Patients with initially unresectable (stage III) neuroblastoma occurring in the pelvis respond well to second-look resection. Children with primary tumors surrounding the celiac axis eventually died despite subsequent resection. Although the efficacy of primary tumor resection in cases of metastatic neuroblastoma remains controversial, stage IV patients with tumor resection had a longer duration of survival. Our only long-term survivors had their primary tumors resected. Second-look or delayed abdominal operations in metastatic cases may be useful in assessing the effectiveness of treatment and for sampling of retroperitoneal lymph nodes as a prognostic indicator.

Nineteen of 74 children with Wilms' tumor underwent second-look laparotomy. Transperitoneal operation was done in five cases referred after flank operation elsewhere. Four had a change in stage from I to II or III, while one considered "inoperable" was resected (4/5 survived). Reoperation was done in two late referrals after operations with tumor spill. One had recurrent flank disease; the other had a flank mass with unrecognized diaphragmatic and intracaval extension (1/2 survived). Three children with giant tumors initially considered unresectable were successfully resected after cytoreduction with chemotherapy (3/3 survived). Two of three patients with bilateral Wilms' tumor survived reoperative procedures (partial or total nephrectomy). Five children with late intraabdominal recurrence (3 liver: 2 flank) eventually died despite reoperation and adjunctive therapy. All five had unfavorable histology. One child with en bloc hepatic resection had successful reoperation for suprahepatic vena caval obstruction due to regeneration of liver, but subsequently died. Ten of the 19 patients survived (52.6%) following reoperation and adjunctive therapy. Second-look laparotomy is quite useful in patients inadequately staged with flank operations, in cases of bilateral Wilms' tumor, and in children with initially unresectable tumors following cytoreduction. Patients with extensive tumor spill at a previous procedure may benefit from early reoperation. Late recurrence of tumor (especially with unfavorable histology) and/or liver metastases carried an ominous prognosis.
