Minimizing Variance in Gastroschisis Management Leads to Earlier Full Feeds in Delayed Closure.

BACKGROUND: Limited guidance exists regarding appropriate timing for feed initiation and advancement in gastroschisis. We hypothesized that implementation of a gastroschisis management protocol would allow for standardization of antibiotic and nutritional treatment for these patients. METHODS: We conducted a retrospective comparison of patients with simple gastroschisis at two pediatric hospitals before and after initiation of our gastroschisis care protocol. Complicated gastroschisis and early mortality were excluded. The control group extended from January 2012 to January 2014 and the protocol group from July 2014 to July 2016. Variables of interest included time to feed initiation, time to goal feeds, length of stay, and National Surgical Quality Improvement Program-defined complications. We performed a subgroup analysis for primary versus delayed gastroschisis closure. Statistical analyses, including F-tests for variance, were conducted in Prism. RESULTS: Forty-seven patients with simple gastroschisis were included (control = 22, protocol = 25). Protocol compliance was 76% with no increase in complication rates. There was no difference in length of stay or time from initiation to full feeds overall between the control and protocol groups. However, neonates who underwent delayed closure reached full feeds significantly earlier, averaging 9 d versus 15 d previously (P = 0.04). CONCLUSIONS: For infants undergoing delayed closure, the time to full feeds in this group now appears to match that of patients undergoing primary closure, indicating that delayed closure should not be a reason for slower advancement. Additional studies are needed to assess the impact of earlier full enteral nutrition on rare complications and rates of necrotizing enterocolitis.

Minimizing variance in Care of Pediatric Blunt Solid Organ Injury through Utilization of a hemodynamic-driven protocol: a multi-institution study.

BACKGROUND: An expedited recovery protocol for management of pediatric blunt solid organ injury (spleen, liver, and kidney) was instituted across two Level 1 Trauma Centers, managed by nine pediatric surgeons within three hospital systems. METHODS: Data were collected for 18months on consecutive patients after protocol implementation. Patient demographics (including grade of injury), surgeon compliance, National Surgical Quality Improvement Program (NSQIP) complications, direct hospital cost, length of stay, time in the ICU, phlebotomy, and re-admission were compared to an 18-month control period immediately preceding study initiation. RESULTS: A total of 106 patients were treated (control=55, protocol=51). Demographics were similar among groups, and compliance was 78%. Hospital stay (4.6 vs. 3.5days, p=0.04), ICU stay (1.9 vs. 1.0days, p=0.02), and total phlebotomy (7.7 vs. 5.3 draws, p=0.007) were significantly less in the protocol group. A decrease in direct hospital costs was also observed ($11,965 vs. $8795, p=0.09). Complication rates (1.8% vs. 3.9%, p=0.86, no deaths) were similar. CONCLUSIONS: An expedited, hemodynamic-driven, pediatric solid organ injury protocol is achievable across hospital systems and surgeons. Through implementation we maintained quality while impacting length of stay, ICU utilization, phlebotomy, and cost. Future protocols should work to further limit resource utilization. TYPE OF STUDY: Retrospective cohort study. LEVEL OF EVIDENCE: Level II.

Congenital diaphragmatic hernia: treatment and outcomes.

Congenital diaphragmatic hernia (CDH) is a congenital defect in the diaphragm that allows herniation of abdominal contents into the fetal chest and leads to varying degrees of pulmonary hypoplasia and pulmonary hypertension. Advances in prenatal diagnosis and the institution of standardized delivery and postnatal care protocols have led to improved survival. Fetal endoscopic tracheal occlusion shows early promise for patients with the most severe CDH, but prospective randomized data is still required. CDH survivors have a variety of associated morbidities that require long-term follow-up and early intervention strategies for optimal care.

Chest tube placement in children during extracorporeal membrane oxygenation (ECMO).

BACKGROUND: Pleural collections of air and fluid are frequent in infants and children treated with extracorporeal membrane oxygenation (ECMO). In this anticoagulated population, chest tube placement is potentially hazardous, and catastrophic hemorrhage has been reported. We sought to define the risks associated with chest tube placement in a large population of children managed with ECMO. METHODS: The records of 189 consecutive children managed with ECMO at two children's hospitals were reviewed. Demographics, indications for ECMO, and ECMO courses were reviewed. In particular, the occurrence of pleural collections and the frequency and technique of chest tube placement were evaluated. The incidence of complications and mortality were determined. RESULTS: The median age of the subjects was 2days. The overall mortality was 26.5%. A pneumothorax was found in 19 (10.1%), a pleural effusion in 26 (13.8%), and a hemothorax in 2 (1.0%). A chest tube was placed in 27 (19 by a needle-guide wire technique and 8 by cut-down). Major bleeding complications occurred in 6 subjects (22%). CONCLUSIONS: There was a significant incidence of major bleeding complications and death in subjects in whom chest tubes were placed. The placement of a chest tube during ECMO should be done only if it is likely to improve pump flow or promote weaning of support.

A multicenter evaluation of the role of mechanical bowel preparation in pediatric colostomy takedown.

BACKGROUND: In response to studies in adults that have failed to demonstrate a benefit for mechanical bowel preparation in colonic surgery, we sought to evaluate the utility of mechanical bowel preparation in a multicenter, retrospective study of children who underwent colostomy takedown. METHODS: The records of 272 children who underwent colostomy takedown at 3 large children's hospitals were reviewed, and the utilization of mechanical bowel preparation and perioperative antibiotics was noted. Length of stay and the incidences of wound, anastomotic, and other complications were compared. RESULTS: A polyethylene glycol bowel prep was administered to 187 children. All subjects received perioperative, intravenous antibiotics, and 52% of those with bowel preps received preoperative oral antibiotics. Subjects in the bowel prep group had a significantly higher incidence of wound infection (P = .04) and longer length of stay (P = .05). Oral antibiotics did not affect outcome. CONCLUSIONS: The use of a mechanical bowel preparation in children before colostomy takedown was associated with a greater risk for wound infection, no protection from other complications, and a longer length of stay. This suggests that bowel preparation may be safely omitted in many children who undergo colonic surgery, thereby reducing cost and discomfort.

Thyroid Nodules in Children: A Single Institution's Experience.

Thyroid nodules in children are uncommon but often present an increased risk of malignancy in comparison to their adult counterpart. Multiple diagnostic modalities are frequently employed to characterize these nodules including ultrasound, radionuclide scans, fine needle aspiration (FNA), thyroid function tests, and evaluation of patient demographics. We chose to evaluate if any of these modalities influence treatment or signify a tendency for a nodule to represent a malignant lesion. A retrospective review of patients <21 years of age who underwent partial or total thyroidectomy from 2004 to 2009 was performed (IRB no. 4695). Other than an FNA indicating a malignancy, there does not appear to be any value to extensive preoperative imaging, nor can patient risk be stratified based upon age. We conclude that there is minimal utility in an extensive preoperative workup in a child with a thyroid nodule.

Survival in congenital diaphragmatic hernia: use of predictive equations in the ECMO population.

BACKGROUND: Equations have been proposed by the Wilford Hall/Santa Rosa (WHSR) and Congenital Diaphragmatic Hernia Study Group (CDHSG) for predicting survival in patients with CDH. The CDHSG stratifies risk based on a logistic regression equation incorporating birth weight and 5-min Apgar score, while the WHSR group uses the difference between maximum pO(2) and maximum pCO(2) as an index of risk. These models have not been applied specifically to the CDH ECMO (extracorporeal membrane oxygenation) population, a group at highest mortality risk. OBJECTIVES: To evaluate the WHSR and CDHSG predictive equations when applied to a population of patients with CDH requiring ECMO life support. METHODS: A single-center retrospective review was conducted on infants with CDH treated with ECMO between 1993 and 2007. Predicted and actual outcomes were compared using receiver operating curve (ROC) analyses in which an area under the curve (AUC) of 1 denotes 100% agreement between predicted and actual outcomes. Kaplan-Meier analyses were also used to compare survival of patients who were risk-categorized according to each prediction model. Minimum pre-ECMO pCO(2) was likewise evaluated as a predictor of survival. RESULTS: Overall survival was 50% in 62 CDH patients treated with ECMO during the study period. The CDHSG equation did not discriminate between survivors and nonsurvivors (AUC 0.55, p = 0.499). The modified WHSR formula showed better discrimination of survival (AUC 0.71, p = 0.004). Lowest achievable pre-ECMO pCO(2) had the highest AUC (0.723, p = 0.003). Patients with minimum pre-ECMO pCO(2) <50 mm Hg had 56% survival, while those with >70 mm Hg had 0% survival. CONCLUSIONS: Equations proposed to predict survival in CDH patients may not discriminate survivors from nonsurvivors in the ECMO population. In this highest risk group, factors such as birth weight and Apgar score are less critical in estimating mortality risk than indicators of ventilation and oxygenation that reflect the degree of pulmonary hypoplasia.

Parathyroid carcinoma in a child: an unusual case of an ectopically located malignant parathyroid gland with tumor invading the thymus.

Parathyroid carcinoma is exceptionally rare in children. Parathyroid carcinoma in the pediatric population most typically presents with significant hypercalcemia and a palpable neck mass. The authors report the seventh case of parathyroid carcinoma diagnosed in a child younger than 16 years. To our knowledge, this case is the first documented case, in the pediatric population, of parathyroid carcinoma in an ectopically located parathyroid gland with tumor invading the thymus.

An unusual cause of small bowel obstruction: herniation through a defect in the falciform ligament.

Small bowel obstruction in children is most frequently seen secondary to postsurgical adhesions. In rare circumstances, obstruction may be the result of an internal hernia through or around the falciform ligament. We report the first case of a strangulated internal hernia around the falciform ligament in a young girl.

Seminars: controversies in the management of pediatric thyroid malignancy.

Thyroid cancer in children is a rare malignancy with unusual biological behavior. It often presents at advanced stages, yet behaves in a benign manner, when compared to its adult counterpart. Surgeons have debated the risks and benefits of aggressive surgical procedures for over a decade. A consensus treatment plan for childhood thyroid cancer has not been achieved, however radical surgical procedures have, in general, fallen out of favor. The best operative and adjuvant strategy for these children can only be determined when a better understanding of the tumor cell biology and genetics of this cancer is known. This review discusses the current controversies in the management of differentiated childhood thyroid malignancy.
